Einstein said that light was constant for all observervers, and that this explained experiments such as Michelson-Morley and Airy's Failure (Funny how there are motionless earth experiments that need to be explained). However, his explanation was directly contradicted by experiments showing that light does change velocity to different observers when motion is involved, including velocities faster than c!

https://wiki.tfes.org/Sagnac_Experiment#Wang_Experiment

Yet, despite the explanation being directly contradicted by experiment, with the admission by mainstream sources that it does contradict relativity, the RE still cling to the belief of terrestrial motion!

There is no motion faster than the speed of light. And light appears to travel at the speed of light for every observer.

What you just claim is incorrect.

Also, the referenced paper in the link you shown does not mention any speed >c at all. Just check yourself.

Incorrect. That experiment was to determine if the aether is a background medium of space which light flows through.

Kindly read the article. The experiment is merely measuring the velocity of light. Aether is just a medium for light like ripples in water.

Quote
Morley wrote to his father that the purpose of the experiment was “to see if light travels with the same velocity in all directions.”

Michelson–Morley experiment is best yet

  “ Physicists in Germany have performed the most precise Michelson-Morley experiment to date, confirming that the speed of light is the same in all directions. The experiment, which involves rotating two optical cavities, is about 10 times more precise than previous experiments – and a hundred million times more precise than Michelson and Morley’s 1887 measurement. ”

The purpose is to measure the speed of light in different directions.

MMX was more than just about measuring the velocity of light.

Dorothy Michelson Livingston, Michelson's daughter, describes the experiment in The Master of Light (University of Chicago Press, 1979), her biography of her father. The following is excerpted from her book:

"In April 1887, Morely wrote his father that he and Michelson had begun a new experiment, the purpose of which was "to see if light travels with the same velocity in all directions." They also hoped to learn from the experiment the speed of the Earth in orbit and in movement with the solar system; whether the ether was moving or stationary; and, most important to Michelson, some clear proof of the ether's actual existence, with which to confront skeptics.”

From:

On the Relative Motion of the Earth and the Luminiferous Ether  (1887)

"On the undulatory theory, according to Fresnel, first, the ether is supposed to be at rest except in the interior of transparent media, in which secondly, it is supposed to move with a velocity less than the velocity of the medium in the ratio, where n is the index of refraction. These two hypotheses give a complete and satisfactory explanation of aberration. The second hypothesis, notwithstanding its seeming improbability, must be considered as fully proved, first, by the celebrated experiment of Fizeau,[2] and secondly, by the ample confirmation of our own work.[3] The experimental trial of the first hypothesis forms the subject of the present paper."

Learning about the motion of the earth and whether aether was stationary or not would have been derived from studying the velocity of light. There were no alternative theories at the time which held that light would not change velocity.

It was assumed that light would change velocities on a moving platform, like a bullet would hit you from a higher velocity if fired from a moving train that was approaching you. This was a correct assumption. It can and does, to even velocities greater than c. The error is assuming that the earth was an object in (horizontal) motion.

Einstein said that light was constant for all observervers, and that this explained experiments such as Michelson-Morley and Airy's Failure (Funny how there are motionless earth experiments that need to be explained).

My mistake. Your post said something about light speeds faster than c, so I wrongly assumed you meant Lijun Wang's experiments.

So I went through the Dr. R.Wang's paper from your link  and I couldn't find the part about the speeds of light faster than c, so now I'm not sure where are you getting this idea from.

I also don't see where Dr. R.Wang is mentioning that his experiment contradicts relativity.

It seems to me none of those experiments are really proving your point, you are just drawing unfounded conclusions. Your argument sounds like this:
1. If aether exists it means the earth must be flat
2. Relativity is killing my best attempts to prove that aether exists
3. If I can prove that relativity is wrong then aether exists

The first problem is, proving relativity wrong doesn't automatically prove the existence of aether. That is a propositional fallacy.

The second problem is you can't really prove relativity wrong. All you have is a pseudoscience paper from a person called "Robert Bennett" who seem to be one of the authors of the book "Galileo Was Wrong The Church Was Right", is that the same person?

That's the same person. Dr. Bennett holds a Ph.D. in Physics and agrees that the experimental evidence for Heliocentrism is insufficient.

I would submit that scientists follow the experiments to their conclusions, and that pseudoscientists do not, however.

Still, since his prediction lead to velocities greater than c and consequently are against relativity which claims that the maximal possible velocity is c this raised a large amount of arguing.

Its highly unlikely that something can move faster than 'c'.

But still, absolutely independent of that, earth is not flat!

So based on an article  written by physicist talking about the experiments done by another physicist we can conclude that an experiment done by a third physicist over a 100 years ago proves that ether exists and thus the earth is flat, is that it? It looks very far fetched.

I will concede that relativity is not perfect and there are things it can't properly explain. That doesn't make it a false or debunked theory and certainly doesn't make the world flat.

Dr. Croca concludes that under certain circumstances speed of light would theoretically (might) be faster than c  as an argument to show that relativity doesn't work in that case. He is not saying that it has been observed to  move faster than c.
"What giants?" said Sancho Panza.

"Those thou seest there," answered his master, "with the long arms, and some have them nearly two leagues long."

"Look, your worship," said Sancho; "what we see there are not giants but windmills, and what seem to be their arms are the sails that turned by the wind make the millstone go."

It says that light 'may' travel faster than c because, depending on which direction things are moving it 'may' also travel slower than c. The Sagnac-type devices show that the speed of light is c +/- velocity.

On the topic of Sagnac from Al Kelly's book:

https://books.google.com/books?id=XVLmihZnsvUC&lpg=PA64&dq=%22Sagnac%22%20%22faster%20than%20c%22&pg=PA64#v=onepage&q&f=false



See the last sentence.

Dr. Gezari in his "Experimental Basis for Special Relativity in the Photon Sector" shows us that Special Relativity is a theory of limited experimental validity and casts doubt on the invariance of c postulate (the same light consistency postulate used to justify the MM and AF experiments).

https://arxiv.org/abs/0912.3818

Quote
ABSTRACT

A search of the literature reveals that none of the five new optical effects predicted by the special
theory of relativity have ever been observed to occur in nature. In particular, the speed of light (0)
has never been measured directly with a moving detector to validate the invariance of c to motion of
the observer, a necessary condition for the Lorentz invariance of c.
The invariance of c can now
only be inferred from indirect experimental evidence. It is also not Widely recognized that essentially
all of the experimental support for special relativity in the photon sector consists of null results.
The experimental basis for special relativity in the photon sector is summarized, and concerns about
the completeness, integrity and interpretation of the present body of experimental evidence are
discussed.

1. INTRODUCTION

One of the most reassuring things we know about modern physics is that the special theory
of relativity has faced a century of experimental challenges, and passed every test. This is
generally understood to mean that every aspect of special relativity has been tested and
validated, beyond any doubt. But all it really means is that every aspect of special
relativity that has been tested has passed the test. This prompts the question, what has
been tested and what has not?

Contrary to the popular view, a search of the literature reveals that the experimental basis
for the special theory of relativity in the photon sector is not robust.

....

2.1. Invariance of c.

There are two necessary conditions for the local Lorentz invariance of c: invariance to
motion of the source and invariance to motion of the observer. Satisfaction of these two
conditions is both necessary and sufficient to validate the invariance of c. Invariance to
motion of the emitting source — Einstein’s second postulate has been convincingly
validated experimentally (Section 3.1). But conspicuously absent from the experimental
record is any published attempt to directly measure the speed of light with a moving
detector to test the invariance of c to motion of the observer.

The experimental validation of the invariance of c is plagued by misconceptions and errors
of interpretation. There is a common misconception that Einstein’s second postulate says
that c is invariant to ‘motion of the source and motion of the observer" and it is
incorrectly presented this way in most textbooks. But the second postulate says nothing
about the observer: “Light is propagated in empty space with a definite velocity 0 which
is independent of the state of motion of the emitting body” (Einstein 1905). The second
postulate was not a new idea in 1905 and it is not unique to special relativity (recall that
the classical wave theory of light also holds that c is invariant to motion of the emitting
source). So observations of moving sources cannot discriminate between special relativity
and the old ether hypothesis, and do not favor one over the other. Of course, it could be
argued that experiments with moving sources and moving observers should be equivalent
and indistinguishable, so the second postulate would apply to the observer as well as to
the source. But in other phenomena involving propagating light (e.g., the Doppler effect
in an optical medium, stellar aberration) motion of the source and motion of the observer
have entirely independent consequences. To claim that source and observer motions are
equivalent without experimental confirmation would be invoking the theory to validate
itself.
Observations of moving sources certainly cannot validate the universal Lorentz
invariance of 0 without observations with moving detectors, or at least experimental
validation of the equivalence of source and observer motions for propagating light, and
these things have not yet been accomplished.

...

It would seem that elements of the classical Sagnac effect conflict directly with special
relativity, however, the prevailing view is that the rotating instrument is a non—inertial
system to which special relativity does not apply (as first argued by Langevin 1921). The
argument goes further to say that an observer viewing the rotating experiment from any
inertial frame would be permitted under the rules of special relativity to measure relative
speeds that differed from c, so the apparent speeds c + v and c - V of the counter—
propagating beams in the instrument frame would still be consistent with special relativity.
However, recently Wang et a1. (2003, 2004) demonstrated the Sagnac effect in a non-
rotating, inertial reference frame using a fiber optic linear motion sensor (FOLMS)
interferometer. They showed that the light travel time in a straight optical fiber in inertial
motion has a first—order dependence on the fiber speed in the local stationary frame, just as
the light travel time in a rotating Sagnac effect fiber optic gyro has a first-order
dependence on the tangential rotation speed of the fiber. The effect was obtained using
both solid and hollow (air core) fibers. If the Sagnac effect can be produced by inertial
motion then the rules of special relativity would have to be applied after all, and the linear
Sagnac experiment would violate special relativity.

...

5. CONCLUSION

Considering the weakness of the present experimental support for the invariance of c — the
fact that observations of moving sources cannot discriminate between special relativity and
the old ether hypothesis, the absence of speed-of-light measurements with moving detectors,
the lack of experimental validation of the equivalence of source and observer motions,
doubts about the interpretation of the classical ether-drift experiments, concerns about the
applicability of the modern isotropy experiments, and the fact that all of the unambiguous
tests of special relativity in the photon sector have produced null results — it cannot yet be
claimed that the local Lorentz invariance of c has been convincingly validated by
observation or experiment.

Gezari appears to agree that Wang's linear Sagnac experiment violates SR and also tells us that SR has never been validated with a moving detector in a laboratory.

So he's not saying relativity is falsified. He's saying it isn't the last theory on the matter. Who wouldn't agree with that? Literally no one.

It sounds like he gave up and is admitting that SR cannot explain why some of its defining postulates are violated in experiment.

He is somehow suggesting that SR only applies to the 'proper scale' of explaining the Michelson-Morley, Airy's Failure, and other motionless earth experiments, but does not apply to the laboratory experiments which show that the speed of light is c +/- v.

Back to the drawing board!

That's quite the interpretation on your part that he "gave up". I don't think you're in a position to make such a claim.

What laboratory experiments show that the speed of light is c +/- v? I'm not seeing that in Wang's 2004 Generalized Sagnac Effect paper.

@Tom

You are grasping at straws. Some lab experiments might put relativity in question. It's scientists' job to question things, but no lab experiment is going to prove that the earth is not rotating or flat.

"What giants?" said Sancho Panza.

"Those thou seest there," answered his master, "with the long arms, and some have them nearly two leagues long."

"Look, your worship," said Sancho; "what we see there are not giants but windmills, and what seem to be their arms are the sails that turned by the wind make the millstone go."

Exactly. No lab experiment would ever claim to have proved or disproved anything for certain. Ironically I guess you could say that scientists spend most of their careers trying to prove themselves wrong in some ways. Once a theory is devised it is put up against more and more stringent testing in search for holes in it. Some theories, such as both GR and SR have stood the test of time rather well but that does not make them perfect.

Many experiments being carried out now - such as those at the LHC for example use equipment and facilities that are well beyond anything an individual could manage on their own. Also the experiments are far too complex in their nature for me or most people to fully understand how those experiments are either derived or carried out. Does that give us (as some FE believers seem to insist) reason to dismiss those experiments?  Of course it doesn't.

Mind you if I do one day see a version of the LHC that is made available on the consumer market to purchase then I might join the queue be one of its buyers.

Why should anything need to keep the fixed stars spinning? If there is microgravity in space then the system or 'firmament' can be kept rotating for the same reason that a fidget spinner would spin essentially forever in space.

Now thats funny Tom, I guess your spinner has some superpower bearings that have zero friction?
