It's defenitely the human perceptive. I guess we humans are just trying to

Now what if all the matter in the universe accumulated into one tiny
conglomerate from which no light escapes. As the matter cools, it contracts
to a point. There is no light outside that point and therefore no space.
That is because so many aspects of space are dependent on light that it
couldn't be described without light. or gravity, for that matter.

How does a negative temperature body emit "blackbody" radiation if it
does at all? I am thinking of the neighborhood of metastable states
where the entropy is a decreasing function of increasing internal
energy.
Read the scholarly reference, then tell that physics group they didn't
do the experiment and publish the results. Am I surrounded by morons?
It's in the refereed literature. It happened. Do you think you can
sacrifice a goat, read its entrails, and belch wisdom?
Negative kelvin temps are real world interesting if you can get rid of
the inert positive temp matrix. Optical hole burning only populates
one excited state. The rest of the stuff is just stuff.
Do you think a working laser rod or a withered crone being MRI'd at
Medicare expense does anything out of the ordinary blackbody
radiation-wise? A population inversion doesn't affect species not
participating. If you invert aligned nuclear spin states the
electrons don't much care. If you try something like EPR or adiabatic
demagnization of paramagnetic salts for cooling, the electrons whose
spins are not aligned and population inverted don't much care about
what is happening to their confreres, ditto the nuclei.
If you took cryogenic atomic ortho-hydrogen in a hellacious flat
magnetic field to align both nuclei and electrons (and prevent
recombination to molecules), then inverted both spins against the
field... I doubt anything would seem amiss in the macroscopic view. I
could be wrong here and would enjoy seeing the math offered in
counterpoint (respecting First and Second Law thermodyanmics
limitiations). Note that even 20-tesla fields don't give you
percentage nuclear alignments vs ambient thermal noise. Your basic 60
MHz proton NMR at ambient temp had a population inversion around 15
protons net out of every million. 300 MHz proton NMR doesn't do a
whole lot better - run the math for kT vs the energy of a 300 MHz
photon and stick it in the population equilibrium equation.

Nope... pretty up to date in fact... When you detect a photon
you detect it at a specific point in time... If you sample it over
a period of time it collapses to a wave function...
Now read all the "new" stuff you can and make a logical argument
that a photon that can only be observed at a point in time travels
at all....You cannot sample one at point a then at point b and say
its the same one.... The only time a photon exist to be observed
is during Zero motion time specific point... Observe it with any
time function and its a EM wave....

No problem with the velocity of a propagated wave traversing non zero
space at c... But no one has observed a photon anywhere other than
at the time specific point of observation... Add time ( or distance) and
you speak only of an EM wave...
There is no validation that a photon moves at all...
The EM wave that is observed as a photon at a point specific
time is a energy signature we detect and decipher to give us
a little ball of stuff understanding... But if I pick up 101.1 FM
Rock on my radio I understand it as sound.. The EM wave
is not what I observer... I observed the data in a way, converted
by a device, that I can comprehend. The act of observing the
photon effects the observation of it, and it can only be observed
or comprehended as a photon at a specific point in time..
Add time or distance to the observation and you observe only
the EM wave...Such is the way of duality...

linear.

when it waves up and down and left and right...

they all wave at once around the one waving
like they were stuck with ......electrons <G>
thier is motion.
just not such that it moves more than it's frequency rate back and forth or
spin.
etc...
. (the more of them we make do it.. the more that surround it will
respond the same..)
.
so it does not shoot across the sky like a ball at all,
but it waves all the little balls that are surrounding it..,
it' picks up vibration of all around it and transfers that vibration
to all electrons it touches.
vibrate and spin and all that fun stuff gives us sound and light and things we
can't see..
and motion of them is electric to me...<G>

I don't know which Tom you are referring to, but he is wrong. The

Uncle Al is quite obviously another geo wanker.
The absense of *light* and quantum/relativity dorks has nothing to with the

Interesting statement!
Now .. I have read some of your replies and I understand
what you are trying to say.
You can detect the photon only once. Therefore you cannot
measure its speed. But ... you forget that you can emit
it once and then detect it once. Then you can measure
its speed.
You also say that it is a particle only when detected.
When travelling, it is an EM wave. But ... when emitted it
is a particle and when detected it is a particle.
So, of course you can define the speed of the photon in
any way you want. I chose to define it as the distance
between the emitter and the detector divided by the time it
takes from emitter to detector. Then it has speed.

No you cannot... There is no method to emit a photon as
a discrete particle... We can only emit a beam of light
,a flash of light, a pulse of light ect... In all cases where
we detect a "photon" it is as a discreet energy signature
of a pulsed or continuous EM wave at the freq. we are
observing... at a zero time frame... Add time , any time
.... and the "photon" collapses to is EM wave..
Such is the way of duality.... It never is a particle in
the sense that it occupies 3d space.. It only seems
to be a particle because of the method of observation
and interpretation. In the same way we observe and
interpret ,using your radio, the EM wave of your

No .. I said it is not and will never be a particle... It is a
EM wave that we detect at Zero time and we perceive
it as a physical particle because of the method of observation..

This is almost reasonable. You cannot define a distance with
a single photon, but only because the information is in correlations,
not because you can't detect the photons.

No... you are only observing zero time slice of the Pulse. And yes
of course it would meet a predicted number of seemingly physical
particles because the device used to "count" photons is observing
the wave in discreet zero time slices at intervals... An we interpret
the data in a way that seems to be a physical particle.

There are lots of processes that emit single photons.
There are also processes that emit dual photons. If
you detect one of the photons nearby and the other
say 1 kilometre away you can measure the speed of
the photon. I see no problems with that.

If it is a particle or not is a matter of definition.
How do you define a particle? If you say that you must be
able to stop it and put it in a box, then it is not a
particle. Because as soon as you stop it disappears.
But, as you say .. when it is detected it is "perceived"
as a particle. Is this not enough to call it a particle?
BTW. I am in rather deep water right now. I don't really
know what I am talking about :)

Point me to a ref for a working process that can be
verified as producing a single or dual photon... Not
theoretical... but that produces a single verified photon..
You may detect a photon if you use a device that is
designed to detect a EM wave at a point in time but
that is not the same as producing a single photon..
In other words.. We ain't done it yet...
If you turn on your radio and get a signal
that is decoded by the device so you hear your
music... The music is not what was observed..
Same concept for all EM waves... If you
sample an EM wave , whether it be Rf, or laser

No I disagree... A particle to be a physical particle must
have physical properties the most important one is
it must occupy a volume of 3d space.. There are more
but that one sets the bar for a physical particle.

Yup it does... because it was never a real little ball of
stuff in the first place.. It was a EM wave measured
with zero time reference.. Take a sine wave and
look at any point along it but at Zero time.. It is at
that specific time a energy "pop" it has no physical
properties just a energy signature.. If I build a device
that can sample that discrete point and get a measurement
it would seem to be a single "particle" but add any
time at all and its a sign wave....

I think it is the best way to do calculations and predictions
but the question was does a photon travel at c... I said
there is no way to validate that it indeed moves at all..

Absolutely... The only reason I keep twistin nipples.. I just want
to get to the point that the data collected by a device is the
extrapolation of the event being observed and is intrinsically
linked to the observer. So sure a photon or any other particle
can be used as a model but there is no way to determine a
particle that has the aspect of duality is in fact a real ball of stuff...

If you detect a photon it will be a zero time slice.. No time .. No velocity..
Add time (any time) mix well and poof.. EM wave....
Any beta-gamma coincidence experiment and in general, gamma
spectroscopy. For experimental information, look under any of the
following: gammasphere, yrast, beta gamma coincidence (e.g, Phys. Rev. C
53 96 (1996)), pair production, pair anihilation, quantum cryptography,
quantum teleportation, single-photon detection. The list is endless.

I agree. Your mumbo-jumbo doesn't require my approval to be mumbo-jumbo.
I wouldn't presume to take credit for the mumbo-jumbo you've created. The
fact that I can't find any real physics beneath the lacadasically crafted
subterfuges and brazen sophistry is merely an indicator of degree not an
attempt to deprive you of any derision by upgrading your conjectures to

And so are you. There are lots of processes
that generates a controllable number of photons.
I suggest that you look at nuclear and particle

There are no links. I just woke up with the idea one morning. These things
happen.
The point is, according to SR in particular, the FORM of space is really
defined by the way in which an observer uses light for communication. Space
changes for different observers because of the way the SEE it, using EM.
How could space exist if there were no light with which to determine its
'shape'?

>How could space exist if there were no light with which to determine its

Well, if there were no signals and no fields whatsoever in a region of
space (and no gravitaitonal field), then it could be argued that the
region of space in question actually has no physical existence.
If there are no gravitational fieldlines that enter the "region", then
there are no lines that you can point along in space to say
"there it is!".
Einstein once wrote that if you take away the gravitational field
parameters, you don't have "empty" space --- you don't _even_ have
space.
If you could take a region containing an object and divert all
external fieldlines so that they all somehow "miss" the object and its
region, then what you've effectively done is to take the object and
its region and blobbed it off from normal spacetime into its own baby
universe.

Paul, the whole of SR is based on an unproven postulate. There is no
logical reason why that postulate should be correct. In fact it is quite
obviously wrong and based on the misconception that OWLS is constant
because TWLS has always measured as constant to within only about 1 part in
10^9 - which is not good enough.
My demonstartions have shown WHY the postulate and its consequences are
wrong.
You agree that nothing *physically* changes with velocity yet you insist
that muons live longer when they travel near c towards earth.
All the so called supporting evidence comes from either null results, fast
moving charged particles or other highly suspect experiments and
interpretations.
Why should I not treat SR as a joke?

Nearly.
I think you are generally right about the basic philosophical
principle, that one should not be able to make physical measurements
of a quantity of "nothing" ("how does reality remember what distance
is supposed to exist between two surfaces, if the distance is truly
empty?"), but you were on more dodgy territory when you brought in
special relativity.
There /are/ arguments in print that, under SR, Minkowski's description
suggests that causal reality is maintained by the way that lightcones
mesh together, and that could suggest to the reader that perhaps
reality might be undermined if those lightcones were blocked, but
under special relativity the geometry is supposed to be fixed and
absolute, irrespective of whether there are really any lightsignals or
observers in the region or not.
This is actually one of the main gripes that I personally have with
the special theory, that its relativistic geometrical description of
the physics of observers exchanging signals does not disappear when
those observers and their signals and fields are taken away. Special
relativity declares that an absolute medium is unnecessary, but it
replaces it with a different entity that still has some worryingly
"absolute" characteristics, and which dictates the form of the
physical interactions without itself being affected ("external
causation").
Under GR-type theories, an explicit medium emerges once again, but
it's no longer an "added" feature (it is the total field that's
already there), and it (hopefully!) no longer has the same "absolute"
properties, it conditions the behaviour of masses, fields and signals,
but they also condition it back -- to pick up an old theme, space
becomes an extension of bodies, and bodies become condensations of
space.
Here's a short chunk from Einstein's "Relativity and the Problem of
Space" ('Relativity' book, Appendix V, pp.150-151) ::
:: " This rigid four-dimensional space of the special theory
:: of relativity is to some extent a four-dimensional analogue
:: of H.A. Lorentz's rigid three-dimensional aether. For
:: this theory also the following statement is valid: The
:: description of physical states postulates space as being
:: initially given and as existing independently. Thus even
:: this theory does not dispel Descartes' uneasiness concerning
:: the independent, or indeed, the /a priori/ existence
:: of "empty space". The real aim of the elementary
:: discussion given here is to show to what extent these
:: doubts are overcome by the general theory of relativity. "
:: ...
So ...
... IMO you did correctly identify a slightly awkward area of SR, but
saying that SR's "spacetime" depends for its existence on the
existence of signals would seem to be wrong ... SR's spacetime
supposes a particular structure that was devised using arguments that
involve the exchange of signals between observers, but under SR, that
structure is supposed to still be there even if the observers and
their fields and signals aren't <ick>.

>It would leave an empty hole in space.
But if no external fieldlines pointed into that hole, we'd be back to
the situation where there was no direction that one could point in to
say "there's a hole over there!" It might be difficult or impossible
for a newcomer to the region to know that anything had been removed.
If we create a repulsive field component shell around a payload region
of space and increase the strength of the component so that the
payload region becomes progressively less connected to the outside
universe, and eventually the shielding effect becomes total, with the
payload region completely disconnected and curved back on itself, then
we effectively have a time-aligned wormhole mouth between our universe
and the future offspring universe that the payload region forms.
Once the separation becomes complete, the connection has closed, the
mouth has healed over again, and any wierd field components associated
with the mouth have been allowed to dissipate, we could be left with a
completely normal-looking region of spacetime.
(OK, ok, so the usual "fieldline" idea probably isn't legal in
situations where connectivity varies with time, but that's another
issue)

But again, if those time coordinates did not relate to anything that
we had any hope of observing ...
If we blob off a baby universe that becomes completely disconnected,
then local time coordinates do exist in that universe branch, but they
don't neccessarily relate to anything in our own universe after the
branchpoint, except indirectly.
You could try to define a sort of arbitrary super-spacetime that
normal spacetime is embedded in, and that might allow you to assign a
superspace volume to a "region" that appears to us as a point, and
assign notional "time" coordinates to layers through that volume, but
that might look like just a clever exercise (unless there was some
clear objective in mind, such as assigning a volume to a region
"behind" a point-particle, outside normal space, as a way of
explaining the particle's properties) .
<BACK TO SCHRODINGER'S CAT>
[CLEFTS AND ENTROPIC FURNACES]
On the other hand, if the Schrodinger shielding is not quite absolute,
and the payload (cat-containing) region stays connected by a small
umbilical, then what we have is a "fold" or "cleft" rather than a
wormhole, there's no illegal geometry-change, and the payload region
can either evaporate into normal space through the cleft, or reenter
with a vengeance when we switch off the shielding.
This /might/ be rather disastrous.
Since the payload region is largely isolated from normal space, its
rate of timeflow might be an awful lot faster than ours (since it
doesn't see most of "our" background gravitation), and when the thing
reenters, a cosmological amount of local time might have elapsed
within the folded region. The cat's fundamental particles might have
decayed, leaving us with E=[cat]c^2 of radiant energy (wiping out your
lab's city centre), or, if the payload region has taken up that energy
by expanding, with a nasty reentry shockwave (again, a bit of a
disaster).
If we want to avoid having ourselves a cat-bomb with 100% mass-energy
conversion, we'd probably need to bleed energy out of the region and
let it evaporate in a (hopefully!) controlled way.
Might be a useful energy-source, but you'd probably want to put in
legislation saying that it could only be used off-planet, just in case
Something Went Wrong
(depending on the reentry characteristics, and what happens when you
reassociate two regions whose physics might have diverged, the
subsequent shockwave might make a conventional fission detonation look
a bit wimpy)

Sure. 4D spacetime is "absolute" in the sense taht every
event is unique, and does not depend in any way of frames
of reference.
So what?
That does not mean that "time" is absolute.
It does not mean that "space" is absolute.
It does not mean that "velocity" is absolute.

Or "days of travel" which has been used for millenniums.
So what? It is utterly irrelevant to the question of whether
or not time and space is related in any way.
In SR, they sure are connected.
The spacetime interval between two events is invariant.
You might say that the spacetime interval is "absolute",
independent of frames of reference.
But the spatial and temporal componens of the interval
(distance and time) depend on the frame of reference.
And SR is as you know a valid theory, very well
confirmed by a lot of experiments and falsified by none.

The wonderful introductory book "Spacetime Physics" (by Taylor and
Wheeler) contains the following analogy: In a kingdom, distances in
the east-west direction are measured in miles, but distances in the
"holy" north-south direction are measured in kilometers. Nobody thinks
much about it, any place is maked by a mile-number and a
kilometer-number and the fact that there is a simple constant that
could relate the two numbers never really occurs to anybody, becayse
clearly east-west and north-south are entirely unrelated, the one
being holy and the other only being a direction.
Until someone realizes that two teams of geometers have used different
references to establish north: one team uses geaographic north, while
the other uses magnetic north. And so two types of maps exists, where
the coordinates of things are slightly different from each other,
while describing the same things and the same relationships between
the things. And the attempt to figure out the conversion form the one
type of map to the other type of map (a rotation, really) leads to the
insight that there's nothing "holy" about the north-south direction
after all and that you can easily convert from one reference frame to
the other by means of some simple trig functions.
I'm not going to give away the ending, of course. Read the book
yourself.

This all comes about because of the assumption that information travels at
light speed and not instantaneously.
I have said before, if an event occurs here now, it occurs everywhere
'now', instantly. Its presence will not be registered however.

Real life experiments are preferable to computer simulations.
Computer simulations by one Henry Wilson are highly likely to be
rubbish. Why should anybody pay any attention to them at all? If the
are soundly based on SR principles and properly executed, they will
confirm the results of real observations. If the do not, they will be
either examples of flawed compuer programming or of an incorrect
application of SR principles.

experiments in the real world. A computer is after all infallible
and thus proves how nature works.

there are NO known experiments which directly support SR.

Paul, the event of your snapping fingers occured at the same instant in
your frame and in mine. Information about that event took a certain time to
reach me.
If we know that delay, we can establish an 'instantaneous' time frame.

My favourite "coordinate system" tale is to do with the ancient
Egyptians. The Nile was critical to their civilisation, their
agriculture depended on it, and it was also their main commerce route,
traders would sail up the Nile in their boats with their sails up,
then drop the sails to drift downstream again with the river flow.
Consequently, "South" became synonymous with "upstream"
(shared hieroglyph = "boat with sails up")
and "North" with "downstream"
(shared hieroglyph = "boat with sails down")
Unfortunately, they later came across another river somewhere north of
Egypt that emptied into the Mediterranean in the "wrong" direction,
and apparently their their naming system couldn't cope.
In desperation, the scribes ended up calling the river something like
"where North is South".

If energy can be neither created or destroyed and the passage of time
creates information and it takes energy to store information, then
information is being destroyed by the passage of time, so the thread
of time is being woven out of strands pulled from what has already
been woven. So the thread of time is not immortal, therefore not
absolute. Like a circle, it simply has no beginning or end.

The passage of time does no such thing,
It does not "create" information,
Information creates itself and time is not needed as a thing
It's only needed as an ABSTRACT.
.
only mass is a thing and time is
just an abstract of a mass (thing)like a Ball moving a distance.(thing) like a
stick
funny,
the first known pendulum looked like a ball on the end of a stick to me too!
<LOL>
so.
time is not REAL at all so it does nothing.
but, the mass and the distance the mass moved
is the ONLY thing that does ANYTHING
in this Universe and probably others too.
:)
Time is supposed to be an absolute to the person that
wants any REAL thing to work.
Don't think clocks measure time for they don't truly measure days..
they measure a mass moving a distance.
and that is not what Time is supposed to be.

Were you not ignorant of physics, you would know that Olaus Roemer
measured OWLS in 1675, which was in fact the VERY FIRST succesful
attempt to measure the speed of light. He got a very good value for
it, too. His main source of error was a very poor value for the
orbital radius of the Earth, rather than a poor time measurement.

Positions are determined by GEOMETRY. Orbits are determined by
looking at how the geometry changes with time. Since there isn'y any
time-based effects from the light source, nothing comes up with the
pretended light beam from the observer that you desperately want to
insert into Roemer's observations nearly 3 centuries before anyone had
technology to do such a thing.
