There is an inherent flaw with physics nowadays. It seems that the
great idea that Einstein contributed was the idea that an observer may
be transported at the speed of light along a path- and there may be a
"sense" that deals with mankind.

There is no such thing as an observer travelling at the speed of light
in Relativity. Especially not in the twin paradox.

xxein: That's a little vague as a question (even though not a
question).

Define your exact problem in another way. A real example? Narrow it
to twins? Can we measure the one-way speed of light directly? What
can we measure about light?

The short answer is that all measurement is relative because we can't
find the absolute. But we can derive c out of it. It's a nice trick
but nobody understands the reality of it.

MM, P-R, twins, Pioneer? It all has a real solution if you
investigate it logically for maybe 30 years or so.

I deal with relativity and cosmology. A little with double-slit,
quantum, and dismiss parallel universes and made up stuff like that.
And although I can realize the idea of a curved space-time, it's
thought genesis and description is far from being right. It's like
watching a clown take the costume and all the make-up off and seeing
him on the street with his wife and kids.

Do you want to know how Einstein was both right and wrong about the
bending of light in gravity? Ask me. But for right now, I need to go
to bed and sleep with my family of pit bulls.

I've got answers that would have made even Einstein want to find out
about.

No. If you want to use SR, then use SR, not some made-up-in-your-mind
theory that you think is SR.
The math of SR specifically excludes any matter from attaining a speed
of c.

Einstein never said what you just said. SR includes the fact that an observer CAN'T be transported at the speed of light along a path. Einstein couldn't have contributed the idea of an observer can move at the speed of light because he said the exact opposite.
Obviously, an observer moving at the speed of light is not inherent in SR, flaw or not. SR is inconsistent with an observer moving at the speed of light or faster along a path.
Einstein also did not deal with extrasensory phenomenon. The psychologist Jung believed that humans were connected by some mystical "sense". However, Einstein did not hypothesize any senses that couldn't be simulated with some sort of electromagnetic or chemical technology.

No. The twin separates from his sibling and travels at a speed less than the speed of light. The assumption in the twin paradox is that the traveling twin can be accelerated to any speed relative to the earth twin that is less than the speed of light.
In most presentations, the traveling twin moves at a maximum speed that is slightly less than the speed of light. However, one twin CAN NOT travel at the speed of light relative to the other twin. Furthermore, one twin CAN NOT travel faster than the speed of light relative to the other twin.
Please go back to whatever reference you used and read it again. You have the twin conundrum very wrong.

John : All experiments thus far which have revealed the twin paradox,
have only required the twins to be in any different state of motion.
So far these experiments have been done with Jet planes etc...

It is possible to conceive of the experiment in terms of light though,
using a light clock, but this so far is an imaginary device.

There is a thought experiment similar to this if we're looking at the
Lorentz time dilation equation. But again, that's using a light clock.

Correct, just as predicted by SR.

But observers are regularly sent *near* the speed of light (and
return) to make comparisons with their "twin".
The observed results are in agreement with SR.

You do know what "observers" mean, right?

Invoking the Lorentz transform, the observed time dilation gives the notion of relative simultaneity and also a symmetric mutual time dilation. The manifestation is so obvious, but there have come scores of alMathematicians (those who can do rudimentary mathematics in a mechanical way without the capability of understanding the actual physics involved) who would fudge this and fudge that until someone discovered a way to resolve the twins’ paradox through the very Lorentz transform. <shrug>

What is a transformation? A transformation including the Galilean, the Voigt, Larmor’s, the Lorentz, and Lorentz’s infinite transformations each involves two observers and one observed. The transformation describes the relationship between how each of these observers observes the observed. Basically in an application, you need to introduce as many transformations as there are to the observed. A transformation with its reciprocal is still the same transformation. It is just that simple. <shrug>

In the scenario of the twins’ paradox, there are two observers and two observed where each observer is observing the other one. An engineer would immediately identify that you need two transformations to complete the analysis, and the result is the very real paradox glaring back at you. On the other hand, an almathematician would use just one transformation and its reciprocal to fudge the result. It turns out that in the case of the Lorentz transformation, one can indeed show a non-existence of the twins’ paradox using the same transformation and its reciprocal. In doing so, this demonstrates how ignorant of the ones doing that of not even understanding the basics of physics. They are clueless as what the Galilean transform is. The sad part is that the self-styled physicists have bought into this nonsense in that past 100 years. Fvcking sad, no? <shrug>

The following link shows exactly how the mathemaGic trick is played out through this misapplication of the Lorentz transform.

An observer is any entity that can measure, compare.
The particles in accelerators near the speed of light are observers
since they are used to compare time intervals, decay rates etc.

Yes. I agree that was a high-ranking story, in terms of scientific interest. But
it now appears that the initial measurement was in error. More measurements will
be made, by the OPERA group and by other groups; few (if any) physicists would
bet on another FTL result.

Well I, for one, say that is a rather gross misrepresentation. Yes, in later
years Einstein referenced his schoolboy gedanken of "riding on a light beam",
and the fact that Maxwell's equations simply do not make sense for such an
observer. This certainly influenced Einstein's thinking on the subject. But it
is a VERY BIG STRETCH to go from that to saying SR was "rooted" in it -- so big
it is tantamount to being wrong [#].

[#] For the simple fact is that in SR it is impossible for any
observer to "travel alongside a beam of light". Such an
impossibility is a VERY IMPLAUSIBLE "root" of a theory.

It simply is not possible to "demonstrate truths" about the world we inhabit.
The human condition prevents it. The best we can do is create models of the
world around us, and demonstrate the VALIDITY of those models. SR has been shown
to be an incredibly accurate and valid model of the world, throughout a rather
large domain of applicability.

Yes. SR meets this condition as well as any other well-established theory, such
as the atomic theory of matter, or the theory of evolution of life on earth.

I have no idea what you mean or where you go this (it is unrelated to this
thread). Yes, many analyses of the "twin paradox" are superficial and contain
either errors or misconceptions. But the basic idea is solid, and has been
experimentally demonstrated -- there is no doubt whatsoever that in the world we
inhabit the elapsed proper time of a clock depends on its path through
spacetime; two identical clocks that start together, separate, and then rejoin
can indeed display different elapsed times between those two meetings.

Global warming modeling has been incredibly accurate in predicting
drought and flood,heatwaves and severe cold snaps and basically every
weather condition imaginable.The theory is so successful that
observational evidence of the same location demonstrate how accurate
predictions of floods/drought are -

Global warming is related to relativity in that there are such people
as science fiction deniers ,some more and some less,who recognize a
science fiction on an industrial scale with all the same sky blue
confidence of groupthink.Relativity is not even an issue,merely a
symptom of a bigger issue.

There are people who treat relativists and opponents like house

Yes but practically we cannot get "two identical clocks" to reach the
speed of light like the twin paradox example. The fact that when we
separate clocks in the real world and rejoin them to find that their
individual measures differ has nothing to do with the twin paradox.

Are you dense, John? As it has been said to you numerous times in this

Time dilation and length contraction don't occur until you near c.
That's why Newton's equations hold good in the real world of the
unaided eye. If you have a jet who fly's a clock at high speeds and
at great speeds around the world and return that clock to find that it
has slowed- this can only be the cause of gravitational influences on
the clock and not a twin paradox.

It _is_ the 'twin paradox'!

Here is a simulation of the 'twin paradox':

http://www.gethome.no/paulba/twins.html

A more real life variant of the 'twin paradox'
can be found here:

http://www.gethome.no/paulba/Satellites.html

Select the scenario "Twin scenario - kind of"
and you will see the two satellites meet at
regular intervals. You can see what the clocks
will be reading. The green satellite will age
15.6 microseconds more than the red satellite
between each time they meet.

They sure do, it's just a question of being able to
measure it, which we can with atomic clocks.

Why isn't this the twin paradox?
The 'twin paradox' is that the proper time of two clocks
travelling between the same two events along different paths
in space-time, may be different. It doesn't matter if
space-time is flat or curved, it is still the 'twin paradox'.

Hafele & Keating did the experiment you describe:

http://www.gethome.no/paulba/pdf/Hafele.pdf

An idealised experiment to show how the calculations
are done can be found here:

http://www.gethome.no/paulba/pdf/H&K_like.pdf

If you compare the clocks of the two aeroplanes,
you will see that the west going aeroplane aged 415 ns
more than the east going aeroplane.
Both planes were all the time at the same altitude,
so the difference can only be caused by their different
speeds in the non rotating frame, the gravitational
effect will be the same for both.
The east going plane move faster and ages less.

The "twin paradox" has no clock "reaching the speed of light". All that is
needed is that the clocks move fast enough so the difference between their
elapsed proper times is large compared to their resolution. For instance, for
the best atomic clocks, driving at highway speeds for a few hours is sufficient,
and an airplane trip round the world is more than sufficient.

Muons are unstable particles that implicitly contain a "clock" that governs
their decay (statistically). They have been used to construct an instance of the
"twin paradox" with speed ~ 0.9994 c.

This is merely a statement about your PERSONAL ignorance: the clocks you know
about are insufficiently precise to display the effect. But there are clocks
that are VASTLY more accurate, and in the real world one MUST account for this
effect if one has sufficiently high speeds and sufficiently good resolution.

This depends IN DETAIL on the construction of the clock. A clock that is broken
is no longer a clock, but merely a pile of junk.

We KNOW that the internal clock that governs the decay of muons is unaffected by
accelerations of ~ 10^18 gee (1 gee = 9.8 m/s^2). That is a truly ENORMOUS
acceleration.

See the FAQ, the experiment of Bailey et al.

Yes, such as the following misapplication of the Lorentz transform

The mistake is definitively pointed out in the following.

The twins’ paradox is a manifestation of the Lorentz transform. It
can easily be shown so and done for you in the above link. So, we
have no idea what you are talking about what this basic idea is. You
mean the stuff you have BELIVED IN? <shrug>

> and has been experimentally demonstrated

What do you mean “experimentally demonstrated”? Do you mean no
experimental observations of the twins’ paradox? Of course, we can
tell you that. It does not require an experiment to tell you that
flying pigs just don’t exist. You don’t have to spend a lot of money,
effort, and energy to look for a paradox. We don’t think you know
what you are talking about. <shrug>

What type of bullshit is that? If you are telling us that the flow
rate of time between two frames of references can be different, we
accept that. So, there is the flow rate of time of the observer, and
there is the flow rate of time of the observed which can be called the
local time. There is no proper time unless you are desperately trying
to spin more mysticism to perpetuate your religion of SR and GR.
<shrug>

Given the Lorentz transform below,

** dx” = (dx – v dt) / sqrt(1 – v^2 / c^2)
** dy” = dy
** dz” = dz
** dt” = ( dt – v dx / c^2) / sqrt(1 – v^2 / c^2)

You can write down the following from the four equations above.

** c^2 dt”^2 – dx”^2 – dy”^2 – dz”2 = c^2 dt^2 – dx^2 – dy^2 – dz^2

Then, you can certainly write down the following.

** c^2 dt”^2 = c^2 dt^2 – dx^2 – dy^2 – dz^2

In this case, dt” is the flow rate of time of “ frame or local time.
So, where is the proper time? It does not exist. <shrug>

Yes, and this proves SR piece of shit since SR is incapable of
predicting such a case without invoking a gross misapplication of the
Lorentz transform. <shrug>

it's called, "conservation of angular momentum,"
or clockworkspiel, at relativistical velocities,
such as that in atoms.

let's see what Nienstein999 says about the "paradox,"
Neinstein998; that's at least N guys,

thus:
deforestation (e.g.) causes much, much
more climate change (as well as CO2) than the incredibly skinny
absorptive
spectrum of CO2, compared to the swampcooler's (water).

but, why is that, given the similar shape of the molecules?... all
that
I can come-up with, later.

thus:
the primary such datum is the total difference
of insolation from equator to pole(s),
one to zero as a first approx., high noon on the equinox.;
hence, the total absurdity of the "hole" in the ozonosphere,
esp. considering that there are so mnay of them,
at any given time.

thus:
it's called that, by the Newtonians, of course. anyway,
it's amazing what you can do with that, or at any rate
with Kepler's three orbital constraints, and a lotta math,
even though the 3-body problem is not generally solved;
there was a conspicuous advance, though,
with the 4-body problem!

atoms have angular momentum,
as do astronauts.

thus:
special relativity, implicitly if not explicity,
relies upon the relativistic effect of trying
to impose the "velocity" of light upon quanta
which are themselves relativisic internally,
viz angular momentum,
as developed by Dirac.

not that I comprehend his math;
it isn't really necessary to do that, since
the "twin paradox" and so on are merely quadratic exercises.

> True that both are magic.

thus:
there's an old paper in *Nature*,
"Rapid collapse of the Eemian interglacial, *sensu strictu*,"
G. Woillard's study of a peatbog in France;
that was the interglacial before "this one,"
the Holocene, if it isn't already over.

of course, a lot of folks just use the term,
Pleistocene, and forget about it.

thus:
you don't get it (and neither do most Einsteinmaniacs)
that there is no absolute vacuum or "void,"
through which light is unable to refract, although
even such a putative void would conform to Snell's law,
its index of refraction being 1.0000.... like, wow,
that space is really flat; and, guess, What?
air's is, like, 1.00000004, because of the "curvature
of spacetime," y'think?

Blaise Pascal thought, y'know, and
he verified this by experiment.

there is tons of mainstream crappola about "zero point energy"
and the vacuum, because of this silly pretense
about an absolute void, which has no substance to it;
no-one has ever found or created one, and
it is strictly impossible.

Maybe it is you misrepresenting the meaning of the words, "travel alongside."
The observer traveling alongside a light beam doesn't have to be traveling at
the speed of light, since the beam isn't moving at all. The wave fronts in the
light beam are moving at the speed of light. However, they are passing the
observer by.
It is like saying someone is walking alongside the train tracks. The
train itself can pass by that person. The person can't move at the same speed
as the train.
The word "alongside" here specifies a direction of motion, not a speed.
The tracks don't move any more than a beam of light moves. However, the train moves very fast, very much like the wave fronts in a beam of light are moving fast.
The observer can't go at the speed of light. Einstein said it again and
again. Therefore, there is sufficient context in his articles to say that
alongside refers to a direction not a speed.
Yes, Einstein and the other physicists of his time all knew about wave
fronts in light. The wave fronts in the light beam move at the speed of light n all reference frames. The "beam of light" is more like a track than the train.
