Aspects of time
LeoK
Place a super slow hourglass and a atomic clock on our moon
after syncronizing these with two similar types of clocks
on our earth.
When reading the changes of the two hourglasses and the
two atomic clocks. You will find that the hourglass on
the moon of course is slower than the hourglass on earth.
And the atomic clock on the moon is faster than the
corresponding atomic clock on earth. (Proof: GPS NAVSTAR.)
(Indirectly proven.)
Means time according to a hourglass is slower on the moon.
And time according to a atomic clock is faster on the moon.
And both types of clocks compared with earth time clocks.
So "my" question is: Is time faster or slower on our moon
compared to time on earth?
What should Einstein say about these SR/GR effects?
And don't say a hourglass isn't a clock. It is actually a clock.
Does this mean that SR/GR effects only is given by atomic clocks?
And SR/GR effects can't be showed with hourglasses. Why so, really?
I know that the precision of a hourglass is not the best of clocks,
but I think we can take the formal question here with this note
in mind.
What is time really and can we trust in time?

Bzzzt--the rate of time flow changes due to the different
gravitational potential and atomic clocks are excellent
devices to measure the flow of time.
Atomic clocks work in free fall (Proof: GPS NAVSTAR.)...
Hour glasses do not! The are designed to work only within a
range of gravitational potential. They aren't even accurate
to one percent... obviously not capable of measuring
relativistic effects.

Bullshit. If so, you are using the hourglass as a gravimeter and not
as a clock.

Faster for not being in so deep a gravitational well, slower for being
on the moving platform vs. the surface of the Earth. You'd better do
the calculations to find out. Looks to Uncle Al that the balance of
GR vs. SR at the lunar surface is not a slam dunk as it is for a GPS
satellite in free fall.

Not really. Most atomic clocks have totaly lousy close in precision due to
the high noise characteristics of the circuitry - dance for joy if your
atomic clock has even -65 DbC close in phase noise. A double oven, SC cut
quartz crystal oscillator can have -120 Dbc phase noise with dome effort and
a lot of money. It all depends on what you want to measure...time is much
smoother for quartz than it is for cesium.

No, it is not in the generality in which you are claiming here: An
hourglass that is lying on its side, for example, is not a clock. The
reason for this is that he hourglass is designed to work in a certain
particular environment in which there is a certain particular
grevitational field in a certain particular direction. Operative term:
"direction".
Imagine that you ensure that your hourglasses always point in the same
direction. If the one on the moon is fixed with respect to the
surface, then the one on earth will have to be turned from upright to
sideways to upside-down to sideways back to upright over the course of
a month. During this time it will show all kinds of sand-flow
(including "backwards") and in the whole average will have measured no
time passing at all.
An hourglass is not a clock. Period. An houglass *in a gravitational
field of a given strength and direction* is a (reasonable
approximation to a) clock.
In the exact same vein, your atomic clock requirs a certain operating
environment -- for example it requires electricity to run and the
atomic clock on the moon will in fact register no passing of time at
all because there's no electrical outlet there to plug it into. You
may think that this is a trivial concern, but it is as much a matter
of ensuring the appropriate environment as providing the hourglass
with 1g of gravity in the right direction.
There are many ways to build clocks, and any new idea you have will
have to agree with all the other clocks in measuring every time
interval in every coordinate system or otherwise you have violated its
operating environment somewhere.

It is found by any observer who employs a clock -- not a "stopped
clock", a "rigged clock", a "backwards running clock" or any such
thing.

Until Einstein, everybody imagined that they knew what time was and
that it was generally agreed upon what it was. It took an Einstein to
note (and point out) that "time" is by no means something that
everybody necessarily agrees upon, unless some procedure can be
established by which everybody can measure time by themselves for
themselves.
So for practical purposes he took time to be "whatever a clock
measures" because he figured that it was universally agreed upon what
a *clock* is. I doubt he imagined someone would claim that an
hourglass that is lying on its side or freely falling (or otherwise in
a different gravitational field from the one it was calibrated in)
would constitute a valid clock.
Old Man
LeoK spews mundane nonsense. The post Newton GTR / SR
effects on hour glass and atomic clock are identical, but the
equivalence principle tells you that, in gravitational free fall, an
hour glass cannot function as a clock. The are no land slides
or water falls in free space. [Old Man]
Carlos L
Hi LeoK
Very suggestive your thoughts and questions about 'time'.
Here is *my* point of view:
(Note: I'm trying myself to understand the issue; so forgive me if I
profit the occasion to analyse some details and I result a bit
boring).
First, I agree with you that we must "take the formal question". The
precision of atomic clocks is contingent and is not the fundamental
issue to choose them or not as time standards for the description of
Physics. For example we can imagine a civilization that has developed
a sophisticated technique to extract high time resolution out of
pendulum clocks but doesn't know how to handle atoms to make precise
clocks out of them.
Next, nobody can claim that the rate of ticking of atomic clocks is a
phenomenon *completely* understood for which all possible physical
influences are known (and can be accounted/corrected for). For example
it can not be ascertained that 'when two identical atomic clocks (at
rest relative to each other and under identical gravitation conditions
but not too close in space to one another) are synchronized and
checked to remain so during a small time interval, they will remain
"indefinitely" in sync'. Because we must always admit the possibility
that yet unknown phenomena or uncontrollable physical influences (e.g.
different local vacuum energy?, different showers of neutrinos?,...)
can desynchronise them. (I am of course not referring to the *random*
de-synchronization that is expected to occur due to the accumulation
of quantum fluctuations that would manifest itself macroscopically in
a measurable way after long periods of observation. Such random
de-sync would not be the problem since it could be averaged out).
Therefore there is *in theory* nothing fundamental that imposes the
necessity in Physics to choose atomic clocks as time standards. We
could *in theory* use quartz clocks, spring watches or, why not,
vacuum sealed pendulum clocks or hourglasses to define the time unit
and standard. (Well, of course, under free fall these last clocks
wouldn't work unless we fix a massive basement to them). But these
pendulum or hourglass clocks are not practical not only because they
are not accurate enough for many experiments but because they are too
much affected by known external conditions and/or local conditions
(e.g. by gravitation). But in theory that should not disqualify them
as alternative time standards because we know the precise laws of the
significant phenomena that affect their rate (e.g.
gravity/acceleration, temperature, etc,...) and we could either (1)
correct their readings for those known influences and obtain time
readings that would (except for accuracy) be similar in all
environments to those of atomic clocks, or (2) forget about all
corrections and redefine our physical laws accommodating them to the
new time standard of a pendulum clock and the "relativity of
position". Doing so we would of course obtain very complicated
physical laws for most phenomena, (some sort of epicycles), but we
could build an internally consistent "physics" that makes correct
predictions. Actually quite a few of today's positivist physicists,
that defend that Physics must only be concerned with making good
predictions and not with interpretations, would be delighted to be the
gurus of this new mathematically sophisticated "physics" in which for
example the duration of an Earth's astronomical day would depend on
the position of observation, being significantly shorter (less number
of pendulum periods) if you are on the top of a mountain (with your
clock by your side) instead of at sea level. *For practical purposes*
this is not the case in mainstream Physics that has adopted a time
standard based on caesium clocks that are affected only in a very
small proportion by gravitation gradients as small as those of our
mountains. But strictly speaking, if we give credit to some physicists
that dare pronounce themselves on the subject, it is correct to
interpret the gravitational red shift as a consequence of the "fact"
that atomic clocks run relatively faster on the mountain than at sea
level (or in other words, it could be experimentally proven that our
astronomical day is slightly longer for the mountain observer).
Considering your first question, "Is time faster or slower on our moon
compared to time on earth?" I would answer:
Strictly speaking, your question has no meaning because, for
mainstream Physics, 'time' is only what an official clock (next to you
and at rest) reads. But if we rephrase your question like this: "Is
the duration of all physical phenomena (after correcting for known
physical influences affecting their rate) the same when measured from
the moon as when measured from the earth ? my guess is that *it is
not* due to the influence of gravitation also on atomic clocks as said
above.
Your second question: "Does this mean that SR/GR effects only is given
by atomic clocks? And SR/GR effects can't be showed with hourglasses.
Why so, really?".
Well, since the time variable that enters our physical laws
corresponds by definition to the readings either of official (atomic)
clocks or of other clock mechanisms that have been synchronized with a
standard clock (and known to remain in sync with it under the
pertinent experimental circumstances), then it is trivial that an
hourglass in sync with an official clock will also show the
relativistic effects. If we instead had defined as our time standard
the readings of some other apparatus that are not always (and/or not
everywhere) proportional to the readings of an atomic clock then we
would obtain different expressions for the laws of that "physics" for
which perhaps the word "relativistic" would never had been coined, but
the underlying reality (i.e. its consequences in our world and our
bodies) would of course be the same whether we describe it one way or
another.
And referent to your million $ question: "What is time really and can
we trust in time?" here are my two cents:
First I think that the concept of "time" in Physics needs some
clarification. For me, 'time is an ordering of events'. By "ordering"
I understand creating a list of all the pertinent events of a system
in which a unique number is assigned (or "assignable" at least in
principle, perhaps giving some functions) to every event so that we
can know if its number is bigger or smaller than that of any other
event of the set. We now need a definition of 'event' that is
consistent with such concept of time. My idea of a basic type of event
is: 'a given set of the space positions of *all* the material entities
of the system under consideration in which to each material entity
corresponds only one position'. For example: a set of the positions of
all the elementary particles together with a map of the radiation
(field) that constitute the physical system. (A similarity can be
found with a frame of a movie-film that also contains space-location
information). I also think that it is possible and useful to allow for
different types of events and use the type that adapts better to the
physical description under consideration. For example, an alternative
type of event to be used in other contexts could perhaps be 'a set of
all the temperatures of all the material constituents of a physical
system (i.e. something like a field of temperatures).
It seems important that the concept of "event" that is agreed, does
not contain any connotations related with movement in space or with
physical change because otherwise the definition would be circular
since the concept of 'time' that we are trying to define is itself a
concept that pretends to describe change and movement. But I see no
problem, in theory, to remove from the concept of event any
association with change since it is just a matter of increasing our
number of "film frames" until we are satisfied that all the pertinent
information of our system is included in static frames (e.g. if there
is some information related with change in what we intend to single
out as a *single event*, we just "divide" that multi-pseudo-event in
two or more actual events, and so on).
In this scenario it must be clear that 'no two events have the same
associated number and therefore no two events can be called
simultaneous'. That concept of event is therefore equivalent to the
intuitive concept that we call "instant". Simultaneity is a concept
that must be applied only to sub-events. A "sub-event" can be defined
as 'a given set of the space positions of *some* (but not all) of the
material entities of the system under consideration'. Two sub-events
are simultaneous if they both appear as subsets of the same given
event.
To complete the 'timing' of a physical system and make it operative
for Physics, not only its events must be singled out, but a unique
number must be associated to each event. This is done by adding a
clock to the physical entities that constitute our system and
assigning to each event some characteristic quantity (reading) of the
sub-event "clock" of each event.
The assertion "Time is absolute" made by Newton and assumed explicitly
or intuitively by everybody until the paradigm shift of special
relativity (SR) can here be understood as the belief that any event of
the system "Universe" can be ordered adequately in relation to any
other event in such a way that a consistent description of all the
physical world can be made without violating causality. Causality is
not violated if any physical phenomena (e.g. some information of
contiguous events) can be fully deduced from the knowledge of events
of *only lower order* in the ordered sequence of events.
I myself, and many others, think that "Time is absolute" and that SR
has made a mess of Physics, (but this post is already too long and I'm
tired so I will argue that, when possible, in another post).

To Carlos,
The problem relativists created is that they contend that when a clock runs
slow, that the rate at which time flows in the clock's immediate vicinity
will be slowed down . When you think about it, the two phenomena have
nothing to do with each other since they do not obey
"the law of cause and effect", i.e. one doesn't follow from the other.
I recently bought an antique barometer and wanted to adjust it so it showed
the correct barometric pressure. To this end I went to a store that sold
barometers to record what they showed the local barometric pressure to be.
To my dismay I found that no two store barometers showed the same reading.
I concluded from this, not that the barometric pressure was different at
various locations in the store, but that the store barometers were
inaccurate.
Since there is no such thing as perfection in this world, it follows that no
clock will keep perfect time. Consequently, even the best of clocks will
lose or gain a few seconds in a million years. Next if you shake these
clocks, change their velocity, temperature, humidity, atmospheric pressure
(vacuum), atmospheric gas mixture and gravitational field and vibration in
which they operate, these same clocks will become even less accurate.
The flow of time on the other hand is constant no matter what, since by
definition we do not allow for short or long seconds. That is to say, a
second is a second is a second! Not only that, but the flow of time is
constant and the same throughout the universe, whether there is a person to
observe it or not.
To a child peek-a-boo is reality, not a game. Grown-ups on the other hand
know,
that just because you can no longer see a person, that doesn't mean that
he/she ceased to exist.
Since relativistic physics is built on a fallacy it leads to all kinds of
silly notions, conclusions and observations. Similarly, you can't count to
ten if you believe that the number 7 doesn't exist or only exists some of
the time, no matter how hard you try.
That is why I maintain that relativistic physics is a religion rather than a
science, because it not only is unscientific and illogical, but also
because it is based on faith instead of reality.
And we all know that you can't argue about a man's faith, because it is
based on the way he feels rather than reason. (We all have a rational AND
an emotional half, which cause us to think and behave the way we do.)
Enjoy, Len.

Ho ho. Attach one end of a rope to an end of the hourglass, the other
end to a pivot. Set hourglass in circular motion. A clock!
Tom Potter
Considering the
" supermassive black hole stretching, tearing apart and partially gobbling
up a star...",
recently reported in the news,
it appears that there are "land slides"
" in free space", or else one has to
be much more specific about what "free space" is.
The fact of the matter is
that times in the sense of change
are exponential changes in populations,
and these changes are quantized using the
dimensionally correct time of the
time periods associated with some body (A clock).
In other words,
the exponential decay of a pendulum
is quantized by a periods count of the pendulum.
The decal of the pendulum is time in
the sense of aging, whereas the pendulum period
is the dimensional time of physics.
The clocks that use the time period
of some oscillating system as its' unit
must in the end, be mapped against
long term exponential changes that occur
such as black holes eating stars,
and the heat death of the universe.
The master (Exponential) clocks end up eating
all of the time period clocks.
Furthermore, time periods are bidirectional,
and it is the exponential clocks
that dictate the direction of time.
Time period clocks are easier to count (Quantize)
but they do not provide time direction,
and thus all of the time data.
Note that the count and direction of
exponentials clock can by quantized
if the unit populations that are changing
are counted, and furthermore
if the steps are not exactly exponential,
when mapped against time period time,
that time period time could be bumpy,
or that factors affecting the population environment
are variable.

Interesting thought Len. I agree with you only in part. From one point
of view, I think that the SR logic is internally consistent when it
contends what you say. After all, the SRists believe (1st postulate)
that all the laws of Physics are the same in whatever inertial frame
and therefore when, to account for the constancy of the speed of
light, they assume that the clocks of a moving inertial frame run
slower than ours they must also admit that all their local (to the
"moving" frame) physical processes (e.g. the aging of the travelling
twin, the baking time of their cakes,...) do also run slower according
to our clocks. Otherwise doing the numbers we would conclude that in
the "moving" reference frame they must be finding laws of physics
different from ours.
Parenthesis: The SRists must (and do) admit that it can not in good
logic be just "an appearance" but "a reality" that when our clocks
read 30' the moving cake is insufficiently baked compared to the ones
we also started to bake at the 'synchronization epoch' t = t' = 0.
But according to what most of us expect from Physics, SR has a feeble
point there, because it gives no clue about "why" all the physical
processes of the "moving" frame slow down at the same rate. They at
most say vague things like "the relativity of time is an intrinsic
property of nature that is not the duty of Physics to comprehend.
Physics is concerned with predictions and not with explanations". I
think that the SRists are not completely stupid and they realize that
if they attempt to give *physical* reasons (e.g. of cause and effect)
to explain why the physical processes of the moving frame slow down at
the same rate, they must invoke objective physical properties of space
affecting all the phenomena. They would next have to admit that the
(real) relativistic effects affecting the moving systems are due to
the specific way in which that physical space acts on bodies that move
relative to it. That would be admitting "absolute space" and therefore
they would have to admit that if the clocks of S' go slower than those
of S it must happen that the clocks of S go faster than those of S'
(and not also slower as they pretend to convince us with the peculiar
logic of "relativism"). But then the trick of setting ad hoc the
clocks to explain the constancy of the speed of light would work only
for one moving inertial frame but not for all and so all their card
castle would fall down.

Agreed that there are no perfect clocks if by this we mean that 'no
two "identical" physical clocks will keep in sync for ever'.

Hmmm, I don't subscribe those words (although perhaps we are both
defending the same basic idea of "absolute time" except for
secondary-importance attributes). I think that the best meaning that
we can give to "the flow of time" is: 'what a given physical clock
(our standard) reads' In that respect I can agree that it is
"constant". But, as I see it, the important attribute of "absolute
time" is just the possibility to synchronize all the clocks of any
physical system in such a way that any event is assigned the same
number (time) by all the clocks (independently of their location and
state of movement). (By "the same number" we can actually understand
numbers whose spread is less than the error bar of our clocks). But as
long as the numbering (and therefore the order) of the events is the
same for all observers we can change our minds about the most adequate
time standard and change all our previous clocks (that gave a sequence
of numbers t) by another type of clocks that (compared to the first
set) read for example Log[t] instead of t.

Agreed. For example the "*relative* time dilation between
relatively-moving clocks" can not be considered to have been
satisfactorily confirmed by experiments. The Hafele-Keating experiment
is very controversial. The Ives & Stilwell experiment can probably be
interpreted as a *real* slow down of the clocks (or atom-oscillations)
when they move at very high speeds relative to the physical space
(aether, vacuum, or whatever name), or more precisely when the
absolute speeds of the emitter and the observer are very different.

Continuing with what I was trying to clarify (mainly to myself) in my
first post in this thread, I am convinced that Physics admits a
consistent description based on "absolute Time". In other words, I
think that all the "reality" of our physical Universe can in principle
be thought as an ordered sequence of events (i.e. some sort of 3D film
frames, each with all the physical entities of the Universe) in such a
way that all observers (whatever their location and/or movement) can
have a local clock that assigns to the events the same number (and
therefore the same order) as do all other observers. That implies
that all observers will agree about which events (or which sub-events)
come first and which after, and about which sub-events are
simultaneous. It is actually that what is meant in general with the
assertion "causality is not violated" (and that is what I want to
subscribe by the moment and not the stronger assertion that I made in
my earlier post).
But even assuming that the physical Universe can be modelled by a "3D
movie-film" (i.e. with absolute time), when we set forth to its
description, we have to face the problem that "we" (its observers)
form part of it and can not just view it "from outside" and simply
proceed to assign increasing numbers to each of the frames (events) of
the 3D movie. Nevertheless, to visualize which kind of clocks must
possess the various observers so that they agree about the timing
(numbering) of the (common by definition) events, it can help to
"imagine" that there actually exists a privileged external observer EO
that has no problems with the description (because he can visualize
all the information in each film-frame and the correct order of the
frames) and guarantees that a consistent description (for all our
local observers) is possible if we are wise enough to set our clocks
to time the events in the right way. (That is just a mental exercise
recommended to some veteran relativists that no longer feel free to
think of Space and Time from the good old conceptual mathematical
point of view but only as measurable quantities of a real observer,
forgetting that a theory is after all a model written in a paper using
well defined mathematical constructs, like Space and Time, that don't
care about SR and can be thought classically).
If the premises of the model are valid (i.e. if a description based on
such concept of absolute Time is possible) then, in principle, to
simplify the problem of synchronization, the best solution would be to
have a *single clock* in the whole physical Universe. That single
clock could be anywhere in space and could have any type of movement
(for the EO it would appear in all the film-frames but not necessarily
always in the same place). The single clock could in principle be any
physical mechanism that outputs in a tape ever increasing rational
numbers. The more numbers per day the better. If the numbers being
output are proportional to some *basic physical quantity* of a basic
phenomenon of nature "measured" automatically by the clock there will
be more chances that the final description (i.e. the laws of Physics)
is simple. (E.g. that "basic" physical quantity could perhaps be the
accumulated number of beats output by *a given* caesium clock, or the
accumulated number of radians of some cyclic adequate astronomical
observation related with the Earth rotation on its axis, etc,...).
The next problem in this scenario of a single Universal clock is to
provide the time readings to any observer whatever his movement and
his place in the "Universe". And this is the delicate point that will
make the description (based on absolute time) succeed or fail. And I
am not referring to the technical difficulties of linking the
Universal clock with signals (e.g. light signals, space ship
messengers, particles, or whatever) to every post of observation, but
to the theoretical problem. The only chance to succeed is to make the
one and only correct prediction about the exact delay that must be
attributed to the signals of each link. That implies *guessing* the
good theories of Physics that describe correctly the velocity of the
pertinent signals in every media that the signals will cross. The "one
way" delay of the signal is the one that has to be correctly deduced
from the theory (Measuring the "two way" delay and dividing it by two
can not be trusted a priori).
Alternately, to provide the time readings to all the observers,
instead of sending signals we could, in the vicinity of the Universal
clock, synchronize other identical clocks with it and then transport
these to the other posts of observation. In this case, the only chance
to succeed with the "Absolute Time description" is to make the good
corrections in the transported clocks to compensate for the physical
perturbations (e.g. speed, gravitational fields,...) that have
affected their basic "mechanism" during their journeys.
The problem in both alternatives is that the exact influences
affecting the signals or the transported clocks must be *guessed* and
implemented into a good operative theory. (The theory need not be a
TOE but a it has to be a correct theory of the pertinent phenomena
related with those signals or clock transports). The *guess* of the
theory will of course be suggested by experimental observations made
with yet non-guaranteed clocks but we must be aware that it can not a
priori be assumed that a physical law describing crude experiments
made with non-guaranteed/non-compensated clocks can directly be as
such incorporated into the sought "correct" theory. It would be
circular reasoning to do that.
Now, my thesis is that SR 'hasn't got right' the issue of
synchronization of relatively moving clocks and is therefore very far
from visualizing the possibility to reincorporate absolute time to
Physics. The wrong track was taken when, to reconcile the experimental
facts (1) light speed is independent is independent of the velocity of
the source, with (2) we measure the same "lab-speed of light" in
vacuum whatever the velocity of our lab relative to the stars, it was
believed that the *only* possible solution was the imaginative theory
(SR) of Einstein in spite of its controversial logic. Unfortunately
some of the predictions made by SR (like those related with the
collision of high speed particles) happened to be much more accurate
than those of Newton's mechanics, and the rest of the story is (also)
well known: an endless 100-year discussion between the defenders of
positivism (SRists) and the defenders of traditional logic and
physical causes. But I am convinced that there is at least another
possible way to reconcile both experimental facts (1) and (2) without
resorting to the "relativity of time": It is always given for granted
that a very brief emission of light once it leaves the emitter
(whether we think of it as a bunch of photons or as a classical
disturbance of the medium) can be characterised as a "body of stuff"
that remains basically together and therefore remains well localized
in space during all its journey to the detector. (I am aware that,
even in vacuum, the mainstream theories actually allow for a
"relatively small" gradual widening of the wave packet due to
statistical indeterminacy considerations, but that is not the widening
that I will refer to). According therefore to mainstream theories if
the supposedly localized light-stuff reaches and triggers a detector
that is at rest in the lab at lab time t, it will happen that, if we
have a second detector moving fast in the lab but passing at time t
next to the first detector, we will observe that it is also triggered
by the light stuff when the lab clock reads t (i.e. at the "3 bodies
space coincidence event" (2 detectors + 1 small "body" of light)).
But then, to account for the constancy of the velocity of light, SR
needs to assume that, in the reference frame of the moving detector, a
clock fixed to this detector, when it passes next to the lab
rest-detector (at the "3 bodies space coincidence event") it will not
show a reading t but a different reading t' (related with t in the
well known ad hoc way such that it can be observed that in both
reference frames the speed of light is c).
If instead (as I have defended many times with no success), it is
assumed: (a) that the light pulse once it leaves the emitter spreads
"completely", like the fragments of an explosion, into bits of a great
plurality of speeds; (b) that each bit (or better, each group of bits
of a given speed) carries with it (i.e. implements in it) at its
specific speed, all the information of the emission (frequency,
polarization, intensity,...), (c) that the physical detectors are only
triggered by "bits" whose speed relative to them is c, then it will
happen that the moving detector is not triggered during the "3 bodies
space coincidence event" but earlier or later (depending of whether it
is moving away or towards the emitter) and it can now be supposed that
the clock of the moving detector is also reading t when it passes
next to the first detector (safeguarding therefore the possibility of
a classical description based on absolute time) . In addition, the
constancy of the velocity of light is also preserved but now it must
be understood as asserting that "the speed of light is always c
relative to the physical detectors, and therefore every inertial
reference frame will measure a speed of light in vacuum equal to c *as
long as its detectors are at rest in such frame*" (I think that it is
only that what the experiments have yet shown. I am not aware that any
light *lab-timing arrival* experiment has been yet made with detectors
of big lab speed).

This is not true if the events are separated in space also. If two stars
go nova, different observers will possibly see the sequence in a different
order, or even simultaneous.
There is no evidence of absolute time in this Universe, with the tools at
hand.

You seem to think space and time "really" have a Galilean character, and
that any apparant deviation from that character is something that must be
explained, while Galileo's invariance of length and universality of time
under transformations is something to just be accepted as a matter of
faith, with no explanation needed. Have you never wondered why separated
clocks in different states of motion *should* stay synchronized?
A *physical* explanation would not be an explanation, but rather a
recasting of the problem in terms of postulates that you don't feel a need
to question, and perhaps that it never occurred to you could be
questioned. But what is the foundation for the assumption of a universal
time? Experimental? "I don't care what the data looks like, that's just
the way things are"?

Have you ever wondered why they should not, and more to the point, can you
show they do not?
It is intuitive that they should.

I certainly do question Enstein's second postulate, and his conclusion
derived from it : "Thence we conclude that a balance-clock [or ceasium
clock] at the equator must go more slowly, by a very small amount, than a
precisely similar clock situated at one of the poles under otherwise
identical conditions. "
Ergo you have not proved time is anything other than absolute.
Do not claim GPS clocks are in any way "under otherwise identical
conditions", they are passing through the Earth's magnetic field.

Black was right.
Space and time REALLY have a Galilean character, the clock at the pole
doesn't tick at a different rate to one at the equator, and relativity is an
imagination.

Please give me references of having been told the answer just one
single time. I actually never had realised before that "SR has a
feeble point in giving no clue about why all the physical processes of
the moving frame slow down at the
same rate" until Len Gaaseenbeck suggested that to me. I have never
posted any opinion before on that specific issue.

When I look at a tree I look at something mother nature created without any
input from me.
When I consider "the flow of time" it is a concept man invented without any
help from mother nature.
The problem is that some people look upon a concept as if it was a real
thing like a tree.
But just because I can think of a thing, that doesn't make it so. Or, to
put it differently, a concept is just in my mind, whereas a tree is
something that is actually there for everyone to look at.
The concept of time was invented and defined by man to keep track of events.
It allows one to meet a friend tomorrow, at noon, at the local pub. It
tells people when to go to work and when to go home etc. But when all is
said and done, the concept of time was originated and defined by man to give
order to his life, that's all.
This being the case, once you agree on its definition, time is invariant for
it to work for all at all times. This makes the concept of time dilation
unreasonable and unworkable because it contradicts the very concept of time
as defined by man for use by man.
As far as mother nature is concerned, not only does the concept of time mean
nothing to her since it was invented by man, but the concept of man-made
time doesn't affect her master plan in any way shape or form because it
isn't part of the REAL world.
One day I talked to a Chinese friend about retirement. We were both looking
forward to it. I mentioned that I would have to watch my weight, if I was
within reach of the refrigerator all day, instead of just at night. She
looked at me and said: you look fine to me, what are you worried about?
It suddenly dawned on me that traditionally in China only the affluent
people were fat since they could afford to eat more than they needed to
survive. Consequently, to be fat was a status symbol which people looked up
to. (This is why Chinese Buddha's are fat as compared to Indian or Japanese
Buddha's et al.)
So I smiled and replied: you are right, it is all in the way you look at it.
My problem is not that I am fat, but that I was born in the wrong country.
Now here we have an example of an actual body which looks the same to all
observers in real terms. Yet conceptually I look unhealthy to a Canadian
but healthy and affluent to a Chinese.
So here we have an example of two different concepts for one reality.
Now we all agree that the way I look remains the same no matter who looks at
me.
Relativists on the other hand maintain that the way you look at things makes
them the way they are. For example, depending on how you look at light, an
observer can turn it into a string of moving light particles or into a
light-wave.
Similarly, relativists agree that fast travelling people don't age more
slowly, as measured by their own clock, than the stationary observer who
stayed at home. Yet relativists also maintain that after the travellers get
back, they will have aged less than the people who stayed home.
So there it is; in reality an object is either white or black. Relativists
on the other hand maintain that a body can be both white and/or black,
depending on who is looking at it.

What is the significance of "it is intuitive"? Do you mean that you
knowingly select an arbitrary set of postulates that you feel comfortable

it should work? What makes "it is intuitive" proof or evidence or

You're more than 100 years out of date. Lorentz assumed that space and
time really have a Galilean character, but in 1904, to make theory match
experiment he had to propose an aether that interacted with matter in a
way that changes the lengths and times that we measure, and does so in a
way that results in a principle of relativity and a speed of light that
will be measured as the same in all inertial frames even if we say it
really isn't the same. If space and time REALLY have a Galilean
character, we'd have to say they really have a Galilean character even if
they don't act like it.
So do you have something more besides "it is intuitive"? Or should we
just take your word for it?

So far that's all you've given. I rely on only one postulate, not two.

I'm not guessing. I'm asking you for proof. You are the one making
assertions.
You are just trying to steer away from the issue, sputtering about
'experiments show', but you have no experiments, do you?
"Thence we conclude that a balance-clock [or ceasium clock] at the equator

Lorentz was trying to prop up the aether theory, and MMX killed it.
MMX is entirely compatible with the velocity of light being source
dependent.
Hence time and space is Galilean.

Take Michelson's word for it. It was his experiment, after all. Don't take
Einstein's word, unless you want to visit Antarctica with a ceasium clock

Good points; but probably I didn't express myself clearly and
thoroughly enough and I think that you are misunderstanding me.
I am not sure what you mean by Galilean "character" but: I do not
believe in a Galilean invariance of physical laws (i.e. in Galilean
relativity) because I believe in a preferred reference frame (in which
the aether can be considered at rest), but I do believe in the
Galilean addition of velocities because I believe that a description
based on the "universality of time" (as you call it) is possible. I of
course believe in experiments and particularly in those of collisions
between high speed particles that disprove Newtonian mechanics (at
those speeds). I believe that the properties of space (aether)
determine the behaviour of physical clocks and all other processes
related with change and movement in some (logically) related way. I
admit the possibility that clocks that move relative to the local
aether or that are located in different gravitational potentials
(different aether parameters) get out of sync with those in other
states (of movement and gravitation). Therefore I do not think that
the "universality of time under transformations is something to just
be accepted as a matter of faith, with no explanation needed". What I
believe is that if we make the right compensations for those local
influences in the rate of the pertinent clocks we can obtain a
description based on absolute time (in which all the observers agree
in the order of all the events).

Yes. Their local aether would have the same parameters.

A physical explanation is a description in terms of simpler and more
fundamental postulated laws or/and entities. I don't care about the
"reality" of those basic entities but just about the power and
simplicity of the new description. Science has progressed mainly
thanks to "explanations". (Dalton's atomic theory and (Bernoulli,
Maxwell, Boltzmann,...)'s kinetic theory of gases are within my
favourites).

The question that your request immediately brings to mind is, how can you
be so confident of your position when it's obvious that you've never
gotten your butt to a library to see if any data supports it? Let me see

Which postulate is that?
My assertions, in themselves, aren't a rationale for selecting one set of
postulates over another. I'm telling you why *you* don't have a rationale
for selecting your set of postulates over others. You're demanding
explanations for postulates when you don't even realize that you don't

I haven't studied the GPS system in detail, I don't know the design of the
clocks or the effects of magnetic fields on them. But it does seem a bit
of a stretch to suggest the magnetic effects accidently coincide with
theoretical predictions.
Is gravitational redshifting also due to the effects of the Earth's
magnetic field?

The only reason MMX killed the Maxwellian aether is because it
contradicted expectations from earlier experiments. The MMX does not
stand alone in that analysis.
MMX is compatible with the velocity of light being source dependent, but
it's also compatible with relativity. And it's not the only experiment
ever done that concerns these issues.

Well, Lorentz's aether theory matches the relevant data. I have other
reasons for preferring relativity, I suppose you could call them
aesthetic. To wit: Lorentz's aether has a hypothetical rest frame that
drops out of calculations of electrodynamics; it's surplus metaphysics.
The unification of electrical and magnetic forces and the requirement of
electromagnetic radiation -- it's not just an accident that an
accelerated electron will radiate, if the principle of relativity
were true then it would be unthinkable that it should not radiate.
Lorentz's theory is a theory of electromagnetism while relativity concerns
all forces, and the strong and weak nuclear forces seem to accord with it.
I know people say general relativity is well supported by the data, but I
don't actually know if the data would select GR versus a
Galilean-covariant Newtonian gravity with a finite speed of gravity. I
don't know if anyone has even studied it, and it's sort of beyond me at
the moment to develop predictions from that model for comparison. Biswas
has produce special relativistic Newtonian gravity, but not Galilean that
I know of. But it would be interesting to be able to compare theory and
predictions and say yes, gravity is definitely relativistic, we've ruled
out Galilean space and time.

Well, I hope I've given some idea above of why special relativity can be
considered "power and simplicity". Aether theories always seem sort of ad
hoc to me, but Maxwell's equations can be derived just from Coulomb's law
and special relativity.

Really?
t =1/(nu), therefore
tau = 1/(nu')
tau = (x-vt)*beta (beta = 1/sqrt(1-v^2/c^2)
and
nu' = nu [ 1-cos(phi).v/c * beta ]
Transverse, you said. So phi = pi/2, cos (pi/2) = 0,
nu' = (nu) v/c * beta
tau = 1 / [(nu) v/c * beta ]
tau = 1 / [(1/t) v/c * beta ] = (x-vt)*beta
t / [ v/c ] = (x-vt) ?

Not at all, YOU don't even realize that all you are doing is making is
assertion after assertion. Waving a list of titles isn't any kind of
evidence or making assertions isn't evidence. Copy and paste the experiment
you like the best and we'll analyze it.
That has nothing to do with time. A rock thrown in the air slows and falls
back, unless it achieves escape velocity. I asked you for evidence of time
dilation.

It's Einstein's. I thought you were an avid library fan. I have a paper copy
of
"Electrodynamics" at home, but since it is evident you've never read
anything about how relativity came into being, you can find it at that web

Sure, and there are other observations that clearly show light is source
dependent.

Uh... those don't look right to me. I'm not even sure which observables
you're describing there.
Galilean Doppler shifting is given by
w' = w (1 - (v/c) cos(theta))
Relativistic Doppler shifting is given by
w' = w(1 - (v/c) cos(theta))/sqrt(1-v^2/c^2)
with w being radians per second. So transverse Doppler shifting, with
theta=pi/2 as you said, would be
w'/w = 1/sqrt(1-v^2/c^2)
The only difference between the two is the factor 1/sqrt(1-v^2/c^2), and
that factor comes from the time dilation effect on the frequency of a
moving source.

Some how I have the feeling that the details of any particular experiment

Oh, he doesn't change it. It's just not enough by itself. Galilean
relativity also has the postulate of a uniform time that's invariant under
transformations. Or equivalently, that lengths are invariant under
transformations.

Can't read everything, can't remember random quotes from everything I have
read, and physics doesn't have sacred scripture.
I see now, from the context, that he's talking about the time dilation of
a moving clock due to the rotation of the Earth, and not about weird
gravitational effects.
So, uh... what point were you trying to make?

If time is passing at a different rate on the mountain, than the
earth's center (due to gravitational difference), then the mountains
will "fly away" eh!!
Both are travelling the same orbit, so if time is different for both,
then they MUST part company. As I have yet to observe this phenomenon,

If I understand you correctly you are interpreting that for SR the
speed of any object, in whatever frame of reference, is "given" by its
proper time and that therefore the mountains and the Earth's centre
have a different speed (e.g. along the Earth's orbit) and they should
fly apart. Fortunately SR does not go so far to say that and it also
assumes that the speed of any object in a given reference frame is
"given" by the clocks of that frame (and not of the objects).
On the other hand, when (like all pre-SR physicists) I think that
"Time is absolute" I'm *not* meaning that we can find some *natural*
mechanism that always (in whatever location or movement) oscillates at
the same rate (compared to an identical mechanism) and say: "eh!!
There it is, the Absolute time!!". I instead think that *any* given
process can change its rate when occurring in other locations (or in
general under other physical influences). I see no problem with that.
I only say that we can in theory (if we are wise enough) always
compensate for those physical perturbations (e.g. speed, gravitational
fields,...) of our clocks and synchronize them ad hoc so that any
observer assigns the same order to any event. I agree here with Len
Gaasenbeek's point of view that ‘the flow of time' (including absolute
time), is a man invented concept.

SR (or rather it's creator, Einstein himself) says
" Thence we conclude that a balance-clock at the equator must go more
slowly, by a very small amount, than a precisely similar clock situated at
one of the poles under otherwise identical conditions. "
Note carefully that this is a measure of time, not of a case of a slow
clock. (There is a footnote that precludes pendulum clocks, and the clocks
are 'precisely' similar. )
This would mean that over a few million years the poles would be leading the
equator by six months and we'd have to go to the opposite side of the sun to
visit Antarctica, and about as far as the rovers "Spirit" and "Opportunity"
are right now to cross the Atlantic. Fortunately airline pilots still use
Galilean calculations or the Earth would look like the rings of Saturn,
which happen to be flat. Relativists need to join the Flat Earth Society,
they have a lot in common.
Of course they have a cop-out, GR cancels the SR effect and we are back to a
Galilean world with Newtonian Mechanics operating as they always have.

Yeah, right. The days don't have sunrise and sunset in that order, because
if it were reversed they'd be nights, and its all in our imagination anyway.
I only imagine that I'm hungry when its 'time' for dinner, I only imagine
I'm tired when its 'time' to sleep'. All of existence is in my imagination,
you are a figment of my imagination, I've never seen you and it is the
computer that produces the words I see on the screen with your name under
them.
Len's imagination isn't balanced by logic, he thinks clocks represent time,
not just measure it.

Comment on time "position fix"???
At exactly midnight, as close as we can agree now using atomic or
whatever, take an angle on the position of a VERY distant galaxy. 6
"hours" later (90degrees of rotation), select another..... (or
several, but they must be at largest possible view). Over time, if the
rotation or orbit of the earth alters (or our galaxy/group) the
direction of these selected targets shouldn't alter, with their
angles/directions compared. Our "clocks" here, could then be
corrected....????????????? This work, or have I f* up?

Careful... If you do this 18 days time we'll be at the equinox, the sun will
be peaking over the horizon everywhere, and it will be hard to spot the
galaxies.
Then consider the Earth will advance in its orbit by 1/4 of a day, which is
close to 1/4 of a degree. Maybe you need a radio galaxy.

I'm afraid they will. The Earth's orbit is elliptical, roughly 91,000,000
miles from the sun at perihelion and 94,000,000 at aphelion. So you'll see
(if you had instruments accurate enough) a slight change in the enclosed
angle between two galaxies. Not only that, but the Earth and the Moon both
revolve about a common centre, so the Earth wobbles around a point that is
just below the surface - then there is precession, the tilt of the Earth
changes just like a gyroscope that is slowing down, and also nutation, which
is a wobble on that too. The precession seem to be about 25,000 years per
cycle. This is the most probable cause of the onset of ice ages, which have
positive feedback. The more snow that falls, the higher the albedo of the
Earth, the more sunlight is reflect back into space, the cooler it gets and
more snow falls. That is somewhat counterbalanced by plant life (including
plankton) which doesn't do as well, less CO2 is taken out of the
atmosphere to be converted to wood or peat bogs, and the CO2 helps trap the
heat (greenhouse effect). Burning the world's coal and oil reduces the total
oxygen, increases the total CO2, that traps the heat, the ice will melt, sea
levels will rise and Florida will do an Atlantis on us and sink beneath the
waves.

Our clocks don't control time. In one sense, some units of time are the work
of man, and this probably what confuses Len. The week, the hour, the minute
and the second are all human divisions. Time itself is measured by the year,
that is the important standard. Leap seconds can be added to the year, along
with leap days (we've just had one), and the position of the earth in its
orbit, relative to the frame of reference the constellations provide, is the
measure of time. That is why I said that if anything so absurd as time at
the pole advancing beyond time at the equator were to occur, such that
100,000,000 years passed at the equator while 100,000,000.5 years passed at
the poles, then the poles would be half the Earth's orbit ahead of the
equator. So Einstein was spouting nonsense, as usual.
Anyway, we can use caesium clocks at the pole and the equator right now, and
he was just plain wrong. There are some bozos that think he was right
because he could pull mathematical stunts on them that they don't
understand.

Einstien has motion,and gravity changing the flow of time. Time
slows to how strong the gravity. Times slows how fast an object is
moving. This shows gravity and speed are equivalent. Bert

Great post. Very entertaining image. Use a Styrofoam Earth with Velcro
on our shoes to keep us from flying off (due to lack of gravity from
nearly massless Styrofoam), and you can cancel the GR "fix", too.
But ...
Have you considered the possibility that folks at the equator might
_measure_ their speed as being somewhat faster than folks at the pole
measure it?
In other words, just because the time base is different, why do you
conclude they must be moving at a different velocity, relative to the
poles?

To have a velocity, they'd have to have an instantaneous velocity.
According to Newton and Liebnitz,
dy/dx = [f(x+h) - f(x)] /h as h tends to zero, where y = f(x)
This maybe something Einstein agrees with, too. He certainly used it.
Now, since we have two frames, we have two velocities betwen them, as
measured from each frame.
These are v = dx/dt and omega = d(xi)/d(tau)
Einstein tell us
xi = (x-vt)/sqrt(1-v^2/c^2),
and Andersen tells us
quote
That is, we can reverse the directions of the frames which is the same as
interchanging the frames,
which - as I have told you a LOT of times, OBVIOUSLY will lead to the
transform:
t = (tau-xi*v/c^2)/sqrt(1-v^2/c^2)
x = (xi - v*tau)/sqrt(1-v^2/c^2)
unquote
But I would prefer to use omega here, even if it has the same value.
x = (xi - omega*tau)/sqrt(1-omega^2/c^2)
We can leave c alone, that is the same in all inertial frames of reference,
otherwise I'd be calling it gamma and that might clarify some confused
people, or confuse some people that are enjoying their clear claret.
So...
xi = (x-vt)/sqrt(1-v^2/c^2), and v = dx/dt.
Since v is constant, the time to travel from 0 to x is t.
This has something to do with integration and the Calculus, I'm not sure
what it is, but as we know, it will take two hours to travel 100 miles if
you drive at 100 mph, with a 1 hour break at the 50 mile marker for the cop
to write up your speeding ticket.
So...
t = x/v.
Therefore
xi = (x- vx/v) /sqrt(1-v^2/c^2)
= (x-x) /sqrt(1-v^2/c^2)
= 0 /sqrt(1-v^2/c^2)
= 0.
Applying this to Andersen's Theorem, which is OBVIOUS,
x = (xi - omega*tau)/sqrt(1-omega^2/c^2)
and we need to determine omega.
omega = xi/tau (which is OBVIOUS),
and
x = (xi - tau*xi/tau)/sqrt(1-omega^2/c^2)
= 0.
Since x = 0 and xi = 0,
The change in x as a function of time is
( Remember [f(0+h)-f(0)]/h = 0 )
so dx/dt = 0 and d(xi)/d(tau) = 0
Hence v = omega. Voila!
So, I have considered the possibility that folks at the equator might
measure their speed as being somewhat faster than folks at the pole
and found them to be the same.
Hence the Earth is flat, like the rings of Saturn, according to the genius
Einstein.

muttering under his breath "and v = 0, but don't tell anyone. Galileo was

Ah ha! An excellent suggestion sir.. but how can we determine those
local properties to make the compensations? And what will be the new
Greenwich England (a certain quantum vacuum, at a certain epoch of the
universe, to which we can sychronize our new smart clocks)? We
haven't even proved the existence of a dependence on a relative speed
yet, or explained mass. And of course nobody will be willing to
abandon the electromagnetic second, its quite nice to be able to tell
time without knowing your local velocity relative to the quantum
vacuum or position in a gravitational well.. Such a temporal ordering
system as you propose will likely only be necessary for future
technologies. I would call it "subtime", and its spatial counterpart
"subspace".

"those basic entities".. I am reading you as meaning the very atoms of
space-time (as trumpeted by a recent Scientific American cover). And
your short paragraph sounds like a good albeit spineless answer to
Mach's critique of Boltzmann: "your atoms don't exist".
I am afraid these ideas will meet similar resistance today. In fact,
many have still not accepted atomism of gases, modern fluid mechanics
texts often ignore this approach entirely, deriving momentum and
energy conservation laws without even mentioning a statistical
distribution of atoms.

I agree. However observers can agree a priori to use one particular
inertial frame, as long as they keep track of their motion with
respect to it. In some sense any inertial frame is a cantidate for
such "absolute time". This is used in the "3+1" calculations of GR.

Ok, and in consideration to your constructive comments I will also
use, in this post, the name "quantum vacuum" instead of the word
"A-----" that gives rise to so many passions and miscommunication.

It remains speculation because no experiments are being done today to
try to detect a preferred reference frame (e.g. the one in which the
quantum vacuum can be considered at rest). No experiments are being
done because SR has been so successful making impressive predictions
that, in practice, it is considered unfalsifiable. (Perhaps not only
"in practice" considering that the length standard (meter) was defined
about 20 years ago as the distance travelled in vacuo by light in 0.xx
seconds).
The M-M experiment was a nice attempt to detect a preferred frame but
from my point of view it can exist a preferred frame and nevertheless
not affect the speed of light (that would still be c relative to any
detector). In respect to light, my guess is that it is the intensity
of light rather than its speed the quantity that is affected by
*absolute* motion. (I underlined *absolute* because I am not referring
to the trivial and evident influence of the *relative* velocity
between the source and detector in the intensity of the detected
light. I am rather proposing to measure the intensity received by a
detector of a given velocity relative to the source when both detector
and source are given different velocities relative to the "quantum
vacuum". Probably the effect would be proportional to only 1-(V/c)^2
where I have called V the *absolute* speed of the light source, and
therefore would be very difficult to detect experimentally). But ok,
I'm only speculating and I'm aware that, as long as mainstream Physics
feels comfortable with its present stuff, no one will dare undertake
nor fund any expensive experiment suggested by speculations of SR
opponents. So probably, until an accidental observation happens to
question SR, what we can do is try to make mainstream Physics feel
uncomfortable with its SR-stuff. (That is why I'm often a bit acid and
sarcastic in my posts, trying to be corrosive for SR, but I must add
that I feel the maximum respect for mainstream physicists, for their
knowledge and for their hard and difficult work). To facilitate the
jump from speculations to experiments, it should also help to work (as
I think you are yourself doing) in theories or models that shine some
light on the inconsistencies of SR and/or show that an alternative to
SR is reasonable and possible. I am more optimistic than you and
believe that earlier than "in the next decade or so" experiments will
show that SR must be honourably (why not) placed together with
"Phlogiston" and "Epicycles" in the shelves of the theories that were
once important and useful in the History of Science.

We need a good theory of "quantum vacuum" that describes consistently
the experimental rate-changes suffered by specific types of clocks
(e.g. atomic) when (1) they move (e.g. relative to the CMBR whose
anisotropy gives a good start for an absolute frame) and/or (2) when
they are located in different gravitation fields. GR is not (for me)
the good theory because it rests on SR and because I am convinced that
when "moving clocks change their rate" it is due to *absolute effects*
for which if clock A tics slower than clock B, then, clock B tics
faster than clock A (and not also slower than A, as SR asserts with
insufficient experimental evidence).

It can be expected that choosing as time standard the rate of a clock
that is at rest relative to the CMBR and in a location of zero net
gravitation forces, "the good theory" of quantum vacuum will give the
simpler recipes for manipulating the clocks of other absolute
velocities and gravitational conditions so that they maintain
synchrony with the first. But in principle any clock of well defined
absolute velocity and gravitation could be chosen as the standard
(just as the Earth was chosen as the standard of absolute rest in the
Ptolemaic description). I agree with you that a reference epoch of the
universe must also be given to nail down the time standard because it
is plausible that the parameters of the "quantum vacuum" (and
therefore some physical "constants") might be slowly changing. But
here I think that any epoch (e.g. 2005 anniversary of SR) can be
chosen with equal rights and expected simplicity.

Agreed, but I would enjoy showing my friends my electromagnetic watch
synchronized to the universal time. The watch, as you suggest, would
have to track both my velocity relative to the quantum vacuum and my
local gravitational parameters. I see some technical problems here:
My absolute velocity should not be (tracked) integrated by inertial
systems that AFAIK would confuse inertial accelerations with
gravitation forces (due to the Equivalence principle of GR). I guess
that it would be good enough to include in my watch an accurate CMBR
analyser. Furthermore my watch's 組ravitational tracking system'
should not be fouled by my inertial accelerations. But if we trust the
Equivalence Principle of GR, the same corrections would be needed in
my watch whether my acceleration is inertial or gravitational; so no
problem with gravitation, my watch could just include for this a
gyro-laser or an inertial platform. But to be sure that the computer
of my watch makes the adequate corrections (to keep in synch with the
standard) I would prefer to add to it a full 倉uantum vacuum
parameters analyser'.

Very interesting Luke your paper "Spin Waves as Metric in a Kinetic
Space-Time" http://www.arxiv.org/abs/gr-qc/0304063 although with my
limited knowledge I have only been able to follow the general ideas in
it but not the details.
I have a question somehow suggested by your paper and the discussions
of this thread. I am aware that there is an increasing interest in
describing the 宋acuum' and its real experimental properties. Your
article is a good example. At the same time I find many articles
describing the properties of 壮pace' (or space-time if they prefer)
from the point of view of General Relativity. My impression is that
both groups of theorists are describing the same stuff (that I
call...you know...) but with completely different paradigms and
languages. The question would be "is it correct and orthodox to say
that GR studies the macroscopic (and cosmological) behaviour of space
while quantum vacuum physicists are interested in the microscopic
properties of space?" I ask this because above when I was
"speculating" about what properties of space might affect the clocks
I was doubting whether to say "gravitational parameters" (e.g. the
components of the local stress-energy tensor) or "quantum vacuum
parameters". Could we draw an analogy between thermodynamics ("GR

("Quantum Vacuum type" description)? Is that one of the things that

Sorry to nose in, but who needs a clock to test light speed source
dependency?
To see which swimmer is faster, all you need is a pool and a starting
gun- then see who hits the wall first. Do it to light, and the
constancy of light will be shown to be a false premise-- and easily
done!
From a distant satellite stationary rel earth, emit a flash of
monochromatic light. At that instant have a fast rocket passing close
to satellite (towards or away from earth), which simultaneously emits
a flash of same frequency. (use same type of emitter). Compare
arrivals of flashes- I predict that they will NOT arrive together!
(distance doesn't need to be known / length of pool)
(time of light travel doesn't need to be known / just do they hit the
wall together). I don't even care if we can't tell which flash
originated where- the fact that the two arrive at different times is
enough to prove without fear of contradiction, light source
dependency.
(the agreement on the simultaneous emissions are by signal between
rocket and satellite, not from earth, and delays can be tested before
launch)
Not a lot of money involved by NASA standards-- will they do it?
Apparently not if those who "depend" upon Relativity theory can avoid
it!

THE TWELVE COMMANDMENTS OF FLAMING
1. Make things up about your opponent: It's important to make your lies
sound true. Preface your argument with the word "clearly." "Clearly, Brian
Hillis is a racist, and a dirtball to boot."
2. Be an armchair psychologist: You're a smart person. You've heard of
Freud. You took a psychology course in college. Clearly, you're qualified to
psychoanalyze your opponent. "Peach Pshawski (God Bless You!), by using the
word 'zucchini' in her posting, shows she has a bad case of .........."
3. Cross-post your flames: Everyone on the net is just waiting for the next
literary masterpiece to leave your terminal. From OPINION to EZ-READER to
PETS to CHIT-CHAT, they're all holding their breaths until your next flame.
Therefore, post everywhere.
4. Conspiracies abound: If everyone's against you, the reason can't
*possibly* be that you're a #anatomypart@. There's obviously a conspiracy
against you, and you will be doing the entire net a favor by exposing it.
5. Lawsuit threats: This is the reverse of Rule #4 (sort of like the Yin &
Yang of flaming). Threatening a lawsuit is always considered to be in good
form. "By saying that I've posted to the wrong group, Didley has libelled
me, slandered me, and sodomized me. See you in court, Didley."
6. Force them to document their claims: Even if Ralph Gagliano states
outright that he likes tomato sauce on his pasta, you should demand
documentation. If Newsweek hasn't written an article on Ralph's pasta
preferences, then Ralph's obviously lying.
7. Use foreign phrases: French is good, but Latin is the lingua franca of
flaming. You should use the words "ad hominem" at least three times per
article. Other favorite Latin phrases are "ad nauseum", "vini, vidi, vici",
"fetuccini alfredo".
8. Tell 'em how smart you are: Why use intelligent arguments to convince
them you're smart when all you have to do is tell them? State that you're a
member of Mensa or Mega or Dorks of America. Tell them the scores you
received on every exam since high school. "I got an 800 on my SATs, LSATs,
GREs, MCATs, and I can also spell the word 'premeiotic'".
9. Accuse your opponent of censorship. It is your right as an American
citizen to post whatever the hell you want to the net (as guaranteed by the
37th Amendment, I think). Anyone who tries to limit your cross-posting or
move a flame war to Netusers is either a communist, a fascist, or both.
10. Doubt their existence: You've never actually seen your opponent, have
you? And since you're the center of the universe, you should have seen them
by now, shouldn't you? Therefore, THEY DON'T EXIST! This is the beauty of
flamers' logic.
11. Lie, cheat, steal, leave the toilet seat up.
12. When in doubt, insult: If you forget the other 11 rules, remember this
one. At some point during your wonderful career as a flamer you will
undoubtedly end up in a flame war with someone who is better than you. This
person will expose your lies, tear apart your arguments, make you look
generally like a bozo. At this point, there's only one thing to do: insult
the dirtbag!!! "Oh yeah? Well, your mother does strange things with
..........."
The Golden Rule of Flaming:
My flames will be witty, insulting, interesting, funny, caustic, or
sarcastic, but never, ever, will they be boring.
Androcles
Aldrin put it there in 1969), and the ISS will soon be carrying experimental
lasers. It won't be much longer before someone points one at the moon and
flame to'discover' the speed of light is source dependent. Then this ng will
be moved to sci.religion.flaming.morons.

Now, he just changed frames _and_ reversed the velocity, which means ...

v isn't constant, it's rotating. Believe it, man, it's true -- the Earth
goes around, it doesn't just translate.
If you think the rotation doesn't make any difference try solving the
counter-revolving twin para ... er, problem. The rotation makes a
b-i-i-i-g difference.

Only in flat space, with flat coordinates, and a flat Earth. With a round
Earth and some rotation thrown in you must restrict yourself to what are
quaintly called "infinitesimal displacements", which negates the value of
the term "OBVIOUS".

That's the correct magnitude, of course, so in this context it must be
wrong. Perhaps the fact that you've switched the signs is where the
confusion creeps in.

No it's not, it's curved, because _everything_ is curved. Einstein said
so, in part II of the Relativity Story.
It's only flat if the partials of the Christoffel symbols are all zero and
they're not. Otherwise he'd have had nothing to write about after SR was
published.

According to what I read Galileo didn't get in trouble for saying the
Earth moved. Lots of church honchos already knew that. He got in trouble
for not crediting God with the motion in his published works. In other
words, he stepped on the toes of the Big Boss.
So his trial was really about politics, not science.

Perhaps true, however people love to falsify things considered
unfalsifiable. The difference with relativity is that it is partially
axiomatic, as you point out. How do you disprove a definition?

I agree. So did Michelson and Morley, Lorentz, Fitzgerald, and
others. With the modern definition of the meter, you are guaranteed
to measure the speed of light as C. If you don't, it means you made
an error in calculating the length of your apparatus. This does not
mean there is no anisotropy of space-time, as you are choosing units
that would transform it away.

The importance of the speed of light, and of Oxygen to living things,

We can't assume the local space-time is at rest with respect to the
CMBR (it isn't). The Earth is not moving through the quantum vacuum
at 300 km/s (about CMBR rest frame speed), nor is it moving through
the quantum vacuum at 30 km/s (earth orbital speed). The local
interstellar cloud, heliospheric magnetic field, and magnetosphere,
all could represent more local space-time flows.

Well, I would certainly say GR is a good theory, though perhaps not
"the" good theory. I agree with you in that I am still not at peace
with the twin paradox, and I think the motion of clock with respect to
the quantum vacuum is the cause of time dilation.

This won't work (see CMBR discussion above). Electromagnetic forces
are everywhere and cause (are) local space-time flows. These will all

Yes, that's what I'm suggesting! I'm afraid I don't have most of the
answers, but I think that paper is a good step forward in that it
represents a model of light in that framework. It is remarkable how
much our physics depends on light, in QM and GR. Also there is a
proposal for a modified version of time dilation that should answer
your questions about the twin paradox.. at least I am going out on a
limb enough to make an experimentally verifiable prediction.
You astutely point out "increasing interest" in this area. I have
been following this closely. A recent cover of scientific american
said "Atoms of Space" (it was about quantum loop gravity). A recent
cover of Science et Vie said "Le Vide et Plein D'Energie", about zero
point energies. It looks to me like these ideas are converging
quickly, people are tearing down all the walls to come up with a
consistent theory. Keep up the good work everyone!
I have been reading your "EVE model" as well Carlos.
http://personales.ya.com/carlosla/model/
I think you are attacking some extremely interesting and important
problems! Or perhaps we are only each other's "audience of one"..
velocity distributions of aetherinos in superspace.. a rather esoteric

But experiments have already been done (confirming the light speed
source
*independency*) where "the distance doesn't need to be known and where
the
time of light travel doesn't need to be known". So they are in that
respect equivalent to your proposed experiment.
For example here is the Abstract of an often cited experiment:
------------
"Is the Speed of Light Independent of the Velocity of the Source?",
Phys. Rev. Lett. 39 1051-1054, 1236(E) (1977).
Kenneth Brecher
Department of Physics and Center for Space Research, Massachusetts
Institute of Technology, Cambridge, Massachusetts 02139
Recent observations of regularly pulsating x-ray sources in binary
star systems are analyzed in the framework of the "emission" theory of
light. Assuming that light emitted by a source moving at velocity v
with respect to an observer has a speed c'=c+kv in the observer's rest
frame, we find that the arrival time of pulses from the binary x-ray
sources implies k<2 x 10-9. This appears to be the most direct and
sensitive demonstration that the speed of light is independent of the
velocity of the source.
------------
> Not a lot of money involved by NASA standards-- will they do it?
Your proposed experiment seems "cheap" as long as the rocket passing
by the satellite uses standard technology but then it would be a very
slow rocket. But many observations (mainly astronomical) have already
confirmed that for those small differences of source speeds no light
speed dependence is observed.
Actually there is no need to chase flies with cannon balls; other type
of experiments can be done and have been done like the famous of
Alvager et al, Physics Letters 12, 260 (1964) that in the lab
"Measured the speed of gamma rays from the decay of fast pi0 (~0.99975
c) to be c with a resolution of 400 parts per million", Well, in this
experiment there are actually measurements of distances and clock
timings involved but AFAIK in a non suspicious and non controversial
way.
> Not a lot of money involved by NASA standards-- will they do it?
> ... Apparently not if those who "depend" upon Relativity theory can avoid

I don't agree. I think that very few physicists depend in a strong way
on the success of Relativity theory. Perhaps some teachers of the
theory... Instead, a great majority of the professional physicists
that depend on experimental funding should be glad to have good
arguments to start a new series of experiments to revise Relativity.
And if it happened that some experiment falsified Relativity a new
revolution of Physics would begin, bringing funds and interesting work
for everybody (theorists and experimentalists).
But don't misunderstand me Jim. We are somehow in the same submarine
(trying to torpedo SR) because although I do trust the evidence that
the velocity of the source does not affect the speed of light relative
to the observer, I instead believe that the velocity of the *detector*
does affect the speed of light relative the observer. As I've said
many times I believe that the speed of light in vacuo is c relative to
the *material detector*. But if the detector is moving relative to the
reference frame of the observer (i.e. to the frame that puts the
clocks and the meter sticks to reference the measurement) then the
observer will assign to light a speed different from c (obtainable
from the detector's velocity by simple Galilean addition of
velocities). And here, I think instead that there is no experimental
evidence discarding this possibility (that would explain many
experimental facts without the need to assume the relativity of
simultaneity, etc...).

I am sure you did not mean what you said, because it is self contradictory.
Measuring the speed of light *relative to the observer* means that the
observer has a detector in his own hands with which to measure thae speed of
light. By definition, then, the speed of the detector *has* to be zero with
respect to the observer. So what exactly is this moving detector measuring?
Surely the speed of light relative to *it*. And then it is once again a
measurement relative to a stationary observer, namely an observer sitting on
this moving detector.
You clearly have your knickers in a twist on this issue.
May I give you some sound advice: Don't ever frame jump. Frame jumping is
unhealthy. Decide which frame you are going to sit and observe from, and
hold all your instruments in your hand while doing so. Any other procedure
is simply courting a logical disaster.

Of course. Didn't you know relativists believe the Earth is flat? That's

A DC9 sits 1/2 a degree nose down on the ground. In the simulation game, as
the nose comes up it passes through zero, and sine of the angle went to -1
because someone didn't know that. The view over the glare shield was of the
runway leaving, upside down. One bit later, the image righted itself.
10000000 - 1 = 00000000 so -0 - 1 = 0 wrong

00000000 - 1 = 11111111 so 0-1 = -1, correct

Non suspicious?
Where does the fast pi0 come from and what is its half life?
I'll tell you, in case you don't know. You bombard a block of beryllium with
protons, that smashes the pions out of the nucleus of the beryllium, the
pions decay and release the gamma photons, still inside the block, its
halflife is too short to escape! So you have a stationary block of beryllium
emitting photons at c. Whoopee, that proves c to a resolution of 400 parts
per million, and says not a damned thing about v.

As for myself, there is ample evidence of c+v right here.

You've been mislead.
Light speed is most definitely controlled by the medium it is in, refraction
is ample evidence of that, but in the absence of any medium it is source
dependent.

Of course it does.

No no. That's relativity. Consider.
"The speed of light is c for all observers."
It seemeth impossible for it to be, for if I walk away from a candle set by
the wall and you walk toward the same candle, we then have some motion
between us. If we then divide that motion equally between us, and impart it
to the candle such that it appeareth to be at rest upon the floor upon which
we walk, how then doth the light divide it's motion between us, that we may
both observe it to be the same?
And if I place another candle on the other side of us beside the opposing
wall, such that it is at rest with respect to the first candle, how then
shall I determine the light I approach and the light I recede from, that
they be of equal motion to me?
And yet one more candle, be it placed between us in the room, at centre,
that we may both recede from it and still determine that the motion of light
from all candles be the same?
I am but a simple man, and sorely perplexed by these deliberations, for it
is truly astounding that these assertions be true. Explain this wondrous
concept any sensible way you can, but gently, for it shall surely confound
me and cause my head to ache.

Don't get to complicated, Carlos.
MMX is evidence of source dependency, but unfortunately inadequate. Source,
medium (air) and detector are all relatively at rest.

I mean exactly what I said. It is not contradictory once you
understand what I am saying. It is very simple once you recognize that
the "observer" (reference frame with the meter sticks and the clocks
at rest in it) is not synonymous of the "detector" (physical apparatus
that is triggered by light). You have actually understood it perfectly
when in defence of SR you argue:

So please answer me this:
Suppose that in a lab we have an emitter E and a detector D. Suppose
for simplicity that at all times E and D are somewhere along the axis
x of the lab. Suppose that D is moving at a very big speed v relative
to the lab in the +x direction. Suppose that the emitter E emits a
short pulse of light when it is (moving or not, it doesn't matter) at
x=0. The lab clock at x=0 reads t=0 when E emits its pulse. Suppose
that the detector is triggered when it is passing the coordinate x=d
and the lab clock at that position reads T.
Question (1): What new definition of speed has recently been
internationally agreed that says that d/T is not the speed of that
light pulse relative to the lab?
Question (2): is d/T = c ?
My answers:
(1) none
(2) d/T = c+v

Then, I suggest that we should explicitly add to SR a 3rd postulate
(that is being implicitly used many times hidden under the euphemism
of "no frame jumping"):
"Any experimental arrangement that contradicts any of the two first
postulates is strictly forbidden".

I am (within my limited influence and skills). There are others with
good credentials. e.g. Ronald R. Hatch http://www.egtphysics.net/

No, Einstein was not an opened Newtonian-physics opponent. I agree
that most of the times in the history of science the new theory "can
be considered" a generalization of the old one to a wider domain of
applicability. The old theory can still be considered valid in its
limited domain of applicability. But that has not always been so
clearly so. E.g. I would not say that Bohr's theory of the Hydrogen
atom is correct according to the wider range and more successful
quantum mechanics that considers that the electron does not follow
classical orbits. But perhaps we have a semantic issue here that would
lead us nowhere.

Perhaps you have here some experimental information about the quantum
vacuum that I'm not aware of. If you assert that so strongly it must
be that there is some really "fundamental" parameter of the quantum
vacuum that is less isotropic in the reference frame of the CMBR than
in some specific frame that I ignore.

Hmmm... Perhaps you mean: that there are other stronger disturbances
that contribute more to the anisotropy of our local quantum vacuum
than our movement relative to the CMBR. But if we want to characterize
the essential of the quantum vacuum we must subtract those contingent
(occasional) external influences (e.g. electromagnetic fields) and see
what is left. On the other hand I don't think that the CMBR is an
external contingent influence but is an unavoidable universal and
constant influence characterizing the quantum vacuum. (Actually I
believe more than that: I believe that the CMBR is just the noise of
the aether and not the remnant of a Big Bang; but please forget this
belief that I can not defend at this stage).

Not only for a mean galactic time. As "explained" above I think that
once the specific external influences (mainly electromagnetic and
gravitational) are removed from the quantum vacuum we are left with a
stuff that will only be isotropic in the frame in which the CMBR can
be considered at rest. It is also my guess that clocks of different
speeds relative to the CMBR will have different ticking rates.
Therefore knowing our speed relative to such CMBR frame will allow us
to correct the clocks for it so that they can keep a good
synchronization with the universal time in which I believe. But its
main interest would be, ok, in outer solar travelling.

Not so! Without exception, frequency is the criteria on which the

Is 300km/sec a realistic goal? The satellite at altitude 300,000km
would give am arrival time difference for flash of 1/1000 sec.
Actually more likely to need the satellite at Mars, giving a better
chance for rocket to achieve speed, and more time for the velocity
difference (time taken back here) to be apparent.

Wrong again! I will be wind-surfing while this light travels. But I
will have a moving photographic plate (or similar situation)
chronicling the events (flash arrivals). If only one spot appears on
the film when I look at it later, indicating both flashes arrived

On the contrary; it is Relativity which is screwed by insummountable
contradictions. That is WHY it REQUIRES "frames of reference". They
are the device through which logic and comparisons are avoided. I
don't "frame jump", for the obvious reason that one cannot "jump" to
that which doesn't exist! If a math problem involving multiple orbits,
accellerations, gravities etc comes up, using a system of multiple
reference frames may help to (say) position a satellite, but it NEVER
proves a REALITY. So you can go jump in your "frame of reference" but
you are in for a dissappointment if you expect to land anywhere but in
the ONLY ONE.

So the flashes will change speed as they encounter different
atmospheric conditions: but will they change TO the same speed, or BY
the same amount?????????/ This is a very important issue (to me), but
will not ruin my experiment, as one certainly will not slow more than
the other, in order to arrive together.

Well those aiming the flash at the mirror had better not be DHRs. As
they don't believe in source dependency, they won't add-in the
velocity (vector) of the ISS, and will miss the mirror. Apart from
that, as the signal will exhibit frequency shift if emission and
target are in motion relative to each other, the age old
frequency/velocity arguement will go round/round/round........

There is not one solitary contradiction in SR. NOT ONE. There are only
misunderstandings by pretentious outsiders like yourself. SR has produced
*no* predictions which have been negated by experiment.
It has produced hundreds of thousands of predictions which have been
verified by experiment. I do mean hundreds of thousands. All the way up to
relativistic gamma factors of 600,000
That is WHY it REQUIRES "frames of reference".
Bollocks. Every physics measurement requires a frame of reference. Even

Well, obviously it needs to be a fair fight.
DHRs have to be balanced by Reasonably Sane Engineers (RSEs).
I wasn't thinking frequency, though.
I was thinking computers that used the GPS for the ISS position and caesium
clocks,
and repeating the pulses to the moon and back constantly.
As the ISS approaches the moon it will emit a pulse that will travel a
distance D at either c or c+v, then it will return at either -c or -(c+v)
and during this interval the ISS will have moved to D-vt. So if c+v, then t
will be less than if c. But...we don't know D yet, because that can only be
found by assuming c and measuring t (which is currently being done).
However, some 45 minutes later the ISS will be receding from the Moon, so it
will either signal c-v or c, and the return will be to D+ut. Now we can
compute
D+ut - (D-vt) = (u+v).t and we have eliminated D.
If c is constant, (u+v)/2 will equal u (and v).
Otherwise it will not.
It should be trivial to hook up a laser, a telescope detector, the GPS, a
caesium clock and an ordinary 2.8 GHz PC into one system and run the
experiment automatically, plotting the results on a monitor as they come in.
It will either be a straight line or a sinusoid that corresponds to the
orbit of the ISS with a chunk missing as the Earth occults the Moon.
Bill Gates could write the software, its trivial, IBM could supply the
hardware, any GPS receiver manufacturer can do their bit along with anyone
else that wants to promote their product.
The ISS is international, so there should be competition between them to do
the supplying, and voila, off we go. We could even get "Marlborough" and
"Coca Cola" on the monitor so that other companies could chip in, and the
press would have a field day.

Particles exceeding c enter the Earth's atmosphere constantly, and produce
Cerenkov radiation. That phenomenon is well known. Here's some pix

Bullshit.
The air has a refractive index of more than 1. The speed of light in air is
therefore less than c. A large fraction of the incident cosmic ray
particles are so energetic that they have speeds higher than the speeed of
light in the atmosphere.
I don't suppose you know that the cone angle of the Cerenkov light is in
fact used to determine the particle speeds.

What a clever little detector! Since it "knew" neither the distance

"There is not one solitary contradiction in SR. NOT ONE."
Proof by assertion, I suppose.
If we place x'=x-vt, it is clear that a point at rest in the system k must
have a system of values x', y, z, independent of time, and if we place
x'=x+vt, it is bloody obvious that we'd have contradiction,
tau = (t+vx/c^2)/sqrt(1-v^2/c^2) <> (t-vx/c^2)/sqrt(1-v^2/c^2)

Bollocks.
Newton predicts that the opening angle between the outgoing particles when
two identical particles colliide elastically will always be 90 deg. (Lab.
coordinates, with the target particle initially at rest)
SR predicts that this opening angle will have a reduction factor of gamma
included, and that the actual value will not be the same for all scattering
angles.
At 200 GeV this implies a shrinkage factor in the opening angle of 200 in
the case of an interaction in which two protons emerge at equal angles to
the incident direction. That is an opening angle of about 15 milliradians
instead of the Newtonian value of 90 deg. Please note carefully that SR and
Newtonian mechanics differ by a factor of 200 in the prediction for this
opening angle. I have participated in a series
of experiments in which this elastic scattering process was studies in great
detail. We found hundreds of thousands of such elastic events in which the
opening
angles were as predicted by SR and none in which the opening angles were
what Newtonian mechanics predicted. We did not use relativity to check
relativity. We used very ordinary wire proportional chamber hodoscopes to
measure positions and hence deduce angles.
I would gladly produce as much more evidence as you can swallow.

On my moving photographic plate, which spot caused by the photons
being compared is in a "different frame of reference, and WHY??
Why cannot the two spots be looked at, and a decision be made, as to
whether the photons arrived simultaneously, or not??????

Perhaps those spaces were in an unsuitable frame of reference for you,
and therefore you were unable to commit yourself-----figures!
As for my math, I know enough to realise that (-1) is an imaginary
concept, and that Relativity employs the arbitrary use of -/+ for
velocity, depending on direction and position, which produces the
"imaginary" scenarios predicted by
AE (see the Lorentz equations for contraction: reverse the
direction of a photon- now it is going at less than 0 speed. Tell me
Franz; have you ever been struck by something travelling at negative
(less than zero) velocity??)
Now YOU may think that (-1)meters +(+1)meters = 0 , but Relativity
involves coordinates, and here your "math" falls down! (-1)->(+1)=2 on
the x axis
Now have another look at Lorentz contractions , and see the arbitrary
application of signage which has caused error in the measurement of
the distance between a moving pair of coordinates.

You are straying very close to the realm of out-right lies! ALL I have
to record the result of my experiment, is a piece of moving film- not
even colour film! If this rates as a detector, a machine which
measures the speed of light, you are a lay-down messire for Dirk's
list! Have another look at the previous, and DON'T get caught out in
such false statements again!

Well smell this!
If my two flashes are emitted from spacecraft 1km apart, what is the
chance of those photons colliding before they reach earth????
...and then this (!)......

Usual handy and informative links, Sam!
Now, if you can just give me the coordinates of this wonderous laser,
with a beam diameter of 1km, I will put this info to use (LOL)
