My claim that SR was the next, logical, easy to take baby step can be
supported with a direct quote from Einstein written at the end of his
life in a letter to Carl Seelig:
"There is no doubt, if we look back to the development of the
Relativity theory, special Relativity was about to be discovered in
1905."
Shubee
Certainly that is historically false. However it seems to be you,
Eugene who had the misconception--Folks know that many of the ideas
did *not* originate with Einstein.
What was uniquely Einstein's was he realized that time and space where
not rigid and fixed, but that they where malleable. Nobody else was
thinking that way.
Adapted from "The Mechanical Universe"
Episode 43: Velocity and Time
In the 1800s Michael Faraday discovered, or I should say
formalized, electromagnetic induction. Given a coil of
wire and a bar magnet...
F = qE + qv x B
Holding the coil stationary and moving the bar magnet
produced an electric current in the coil. Similarly
holding the bar magnet stationary and moving the coil
also produced an electric current in the coil.
But in the language of electrodynamics of the day the two
cases were distinct independent phenomena that had
completely different explanations.
When Albert Einstein saw that, he said "Look guys, you've
just got to be kidding--Any yo-yo can see that these are
the same thing".
So it was this little experiment that was really the
start of relativity, not the Michelson-Morley
Experiment--not some exotic experiment to detect the
motion of the earth through the aether.
With this simple little phenomenon, that of course
everybody knew about, disturbed nobody else, but Albert
Einstein.
This led him to write a paper that landed on the desks of
Annalen der Physik on 30 June, and would go on to
completely overhaul our understanding of space and time.
Some 30 pages long and containing no references, his
fourth 1905 paper was titled "On the electrodynamics of
moving bodies" (Ann. Phys., Lpz 17 891-921).
In the 200 or so years before 1905, physics had been
built on Newton's laws of motion, which were known to
hold equally well in stationary reference frames and in
frames moving at a constant velocity in a straight line.
Provided the correct "Galilean" rules were applied, one
could therefore transform the laws of physics so that
they did not depend on the frame of reference.
However, the theory of electrodynamics developed by
Maxwell in the late 19th century posed a fundamental
problem to this "principle of relativity" because it
suggested that electromagnetic waves always travel at the
same speed.
Either electrodynamics was wrong or there had to be some
kind of stationary "ether" through which the waves could
propagate.

Eugene, re-read the first two paragraphs of Einsteins 4th 1905 paper...
ON THE ELECTRODYNAMICS OF MOVING BODIES
By A. Einstein
June 30, 1905
It is known that Maxwell's electrodynamics--as usually
understood at the present time--when applied to moving
bodies, leads to asymmetries which do not appear to be
inherent in the phenomena.
Take, for example, the reciprocal electrodynamic action
of a magnet and a conductor. The observable phenomenon
here depends only on the relative motion of the conductor
and the magnet, whereas the customary view draws a sharp
distinction between the two cases in which either the one
or the other of these bodies is in motion. For if the
magnet is in motion and the conductor at rest, there
arises in the neighborhood of the magnet an electric
field with a certain definite energy, producing a current
at the places where parts of the conductor are situated.
But if the magnet is stationary and the conductor in
motion, no electric field arises in the neighborhood of
the magnet. In the conductor, however, we find an
electromotive force, to which in itself there is no
corresponding energy, but which gives rise--assuming
equality of relative motion in the two cases
discussed--to electric currents of the same path and
intensity as those produced by the electric forces in the
former case.
Examples of this sort, together with the unsuccessful
attempts to discover any motion of the earth relatively
to the "light medium," suggest that the phenomena of
electrodynamics as well as of mechanics possess no
properties corresponding to the idea of absolute rest.
They suggest rather that, as has already been shown to (1)
the first order of small quantities, the same laws of
electrodynamics and optics will be valid for all frames
of reference for which the equations of mechanics hold
good. We will raise this conjecture (the purport of which
will hereafter be called the ``Principle of Relativity'')
to the status of a postulate,
and also introduce another postulate, which is only (2)
apparently irreconcilable with the former, namely, that
light is always propagated in empty space with a definite
velocity c which is independent of the state of motion of
the emitting body.
These two postulates suffice for the attainment of a
simple and consistent theory of the electrodynamics of
moving bodies based on Maxwell's theory for stationary
bodies.
The introduction of a "luminiferous ether" will prove
to be superfluous inasmuch as the view here to be
developed will not require an "absolutely stationary
space" provided with special properties, nor assign a
velocity-vector to a point of the empty space in which
electromagnetic processes take place.
And, of course the paper goes on to develop the ideas
and make his case...

Adapted from "Five papers that shook the world"
by Matthew Chalmers
January 2005
True to style, Einstein
swept away the concept of the ether (which, in any case,
had not been detected experimentally) in one audacious
step. He postulated that no matter how fast you are
moving, light will always appear to travel at the same
velocity: the speed of light is a fundamental constant of
nature that cannot be exceeded.
Combined with the requirement that the laws of physics
are the identical in all "inertial" (i.e.
non-accelerating) frames, Einstein built a completely new
theory of motion that revealed Newtonian mechanics to be
an approximation that only holds at low, everyday
speeds.
The theory later became known as the special theory of
relativity - special because it applies only to
non-accelerating frames - and led to the realization that
space and time are intimately linked to one another.
In order that the two postulates of special relativity
are respected, strange things have to happen to space and
time, which, unbeknown to Einstein, had been predicted by
Lorentz and others the previous year.
For instance, the length of an object becomes shorter
when it travels at a constant velocity, and a moving
clock runs slower than a stationary clock.
Effects like these have been verified in countless
experiments over the last 100 years, but in 1905 the most
famous prediction of Einstein's theory was still to come.
After a short family holiday in Serbia, Einstein
submitted his fifth and final paper of 1905 on 27
September. Just three pages long and titled "Does the
inertia of a body depend on its energy content?", this
paper presented an "afterthought" on the consequences of
special relativity, which culminated in a simple equation
that is now known as E = mc^2 (Ann. Phys., Lpz 18
639-641).
This equation, which was to become the most famous in all
of science, was the icing on the cake.
"The special theory of relativity, culminating in the
prediction that mass and energy can be converted into one
another, is one of the greatest achievements in physics -
or anything else for that matter," says Wilczek.
"Einstein's work on Brownian motion would have merited a
sound Nobel prize, the photoelectric effect a strong
Nobel prize, but special relativity and E = mc^2 were
worth a super-strong Nobel prize."
However, while not doubting the scale of Einstein's
achievements, many physicists also think that his 1905
discoveries would have eventually been made by others.
"If Einstein had not lived, people would have stumbled on
for a number of years, maybe a decade or so, before
getting a clear conception of special relativity," says
Ed Witten of the Institute for Advanced Study in
Princeton.
't Hooft agrees. "The more natural course of events would
have been that Einstein's 1905 discoveries were made by
different people, not by one and the same person," he
says. However, most think that it would have taken much
longer - perhaps a few decades - for Einstein's general
theory of relativity to emerge.
Indeed, Wilczek points out that one consequence of
general relativity being so far ahead of its time was
that the subject languished for many years afterwards.
The aftermath
By the end of 1905 Einstein was starting to make a name
for himself in the physics community, with Planck and
Philipp Lenard - who won the Nobel prize that year -
among his most famous supporters. Indeed, Planck was a
member of the editorial board of Annalen der Physik at
the time.
Einstein was finally given the title of Herr Doktor from
the University of Zurich in January 1906, but he remained
at the patent office for a further two and a half years
before taking up his first academic position at Zurich.
By this time his statistical interpretation of Brownian
motion and his bold postulates of special relativity were
becoming part of the fabric of physics, although it would
take several more years for his paper on light quanta to
gain wide acceptance.
1905 was undoubtedly a great year for physics, and for
Einstein. "You have to go back to quasi-mythical figures
like Galileo or especially Newton to find good
analogues," says Wilczek.
"The closest in modern times might be Dirac, who, if
magnetic monopoles had been discovered, would have given
Einstein some real competition!" But we should not forget
that 1905 was just the beginning of Einstein's legacy.
His crowning achievement - the general theory of
relativity - was still to come.

Let's not be too dogmatic here. It could be a realization. And it
could be a mathematical fantasy.

I've attended worship services in Christian churches and physics
classes on relativity. My strongest recollections are that I've seen
greater and more worshipful devotions expressed for Einstein in
physics than Christians confess for Jesus Christ.
Attributing Poincaré's principle of relativity to Einstein, for

A realization it was... It was that simple little phenomenon, the coil
and the bar magnet, that of course everybody knew about, disturbed nobody
else, but Albert Einstein.
Just because many appreciate what Einstein achieved, doesn't mean they
are blind followers. Einstein's work has been tested for over a hundred
years and not found to be wrong. The data tells the story. There has not
been a prediction of relativity that has been contradicted by an observation.
When there is, relativity will be wrong. But there has not been one! Doubt
is at the heart of science. Relativity survives.

I'm not surprised. Jesus had many teaching--religion would benefit
by concentrating on those teaching. Einstein, on the other hand, gave
us testable theories that have been remarkable tools in furthering
our understanding of nature.
By what right do you feel you understand what most physicists believe?
Your undergraduate education wasn't in physics. You never completed
your graduate studies - not even a Masters.
After 20 years or so, your only accomplishment is a derivation of the
x,t Lorentz transformations. Which I can do in a much more cleaner and
mathematically precise fashion with ten minutes of work.

Every great religion was founded upon words of wisdom spoken by someone
that said something to the effect 'follow none blindly, you must find your
own path to truth'.
Every powerful religion has been based on ignoring most of those words of
wisdom and finding ways of interpreting those words not ignored so as to
enhance the power of those in power.
Science has its share of 'priests', but science is based upon TESTING
ideas, so even the priests must give advise that -- if followed -- would
lead to their downfall as priests, if the theories they espouse are wrong.
Each year there is a fresh crop of rabble rousers that question everything,
and that is how science advances.
It does NOT advance by trying to PROVE a favorite theory, as many of the
would-be 'religious reformers' that hang around here try to do.
If you have information about an experiment, a reproducable experimentm
that falsifies any part of SR or GR, by all means publicize that fact.
Not a proposed experiment, one that you and others have run.
If you just have a different way of explaining results that are already
well explained, then you are wasting our time and yours until you have DATA
that the current theories can not explain.
On the other hand, if you are one of the potty mouthed 'pseudo scientists'
that hang around here and make scientists _look_bad_ by how you act, then
you are worse than those you denegrate.

The implicit assumption is that no model that fails to explain all known
data AND to be mathematically and logically consistent would be 'accepted'
for long.

I hope you don't pretend that your claim that "time and space where
malleable" is physics. And it certainly isn't contained in
Einstein-1905. However, a new VIEW of space and time was indeed
preached years later, by Einstein's mathematics teacher Minkowski.
Minkowski pretended:
"The views of space and time which I wish to lay before you have
sprung from the soil of experimental physics, and therein lies their
strength. They are radical. Henceforth space by itself, and time by
itself, are doomed to fade away into mere shadows, and only a kind of
union of the two will preserve an independent reality."
Harald
You are so out of touch with the history of mathematics that it's
sad. You should educate yourself:
Ryskamp, John Henry, "Paradox, Natural Mathematics, Relativity and
Twentieth-Century Ideas" (May 19, 2007). Available at SSRN:
http://ssrn.com/abstract=897085
He later showed that there is no asymmetry with respect
to Maxwell's electrodynamics. See the Einstein-de Haas
effect, and also the Barnett effect, which are practically
never referenced.
It relates the triple orthogonal electro-magnetic-motion
relation of electromagnetic energy.
I wrote this little piece to refocus attention on these effects
http://www.wbabin.net/science/michaud3.pdf
The issue hinges on the fact that the loose electrons in
the conductor are held captive by the bar magnet due
to forced reverse alignment of the spins of these electrons,
so when the coil is moved, the electrons tend to remain
stationary with respect to the bar magnet, which causes
them to circulate in the coil if the coil is moved.
the reverse process has the very same cause, if you move
the bar magnet inside the coil, then the electrons will
circulate for the same reason, in this case, they simply
follow the magnet.

The absurdity of your view is very plain from your abstract: "our

Little children know intuitively that a tiny arrow that moves steadily

have no understanding of relativity and that children have a better

I don't know where you got that idea. I wasn't taught that. Nor did I
teach my students that. If you were subject to a mistake on that
score, that's a pity, but by no means should you assume the mistake is
widespread.
What Einstein did is synthesize a number of existing ideas, and he
furthermore carried them further than the others with the preceding
ideas were willing to take them. It is the *latter* that Einstein is
most noted for, not for the pure originality of his ideas. And THAT is
historical fact.
Then you were in the wrong place. Pity. Perhaps you should have

Ah, but Einstein had always denied this and many physicists still
believe Einstein.
Consider this reference:
Einstein has always denied to have known Poincaré publications. It's
hard to believe as his friends Maurice Solovine and Carl Seelig,
report Einstein had read the Poincaré book " La Science et
l'hypothèse" (no absolute time, no absolute space, no ether ... )
around 1902-1904. This book was commented at their reading commitee «
Académie Olympia » during several weeks (ref. 8, pages 129 et 139 ;
ref. 9, page VIII and ref. 17, page 30) His position at the Swiss
office patent in charge of "electromagnetism" implied that part of his
job was to read and summarize the main publications on this topic ( he
summarized several papers from the French "Academie des sciences").
At the end of his life, Einstein wrote in 1955 in a letter to Carl
Seelig:
«There is no doubt, if we look back to the development of the
Relativity theory, special Relativity was about to be discovered in
1905. Lorentz already noticed that the transformations ( named Lorentz
transformations) were essential in the Maxwell theory and Poincaré had
gone even further.
At that time I only knew Lorentz work of 1895, but I knew neither
Lorentz nor Poincaré further work.
This why I can say that my work of 1905 was independent » (ref 8, page
11).

Your presentation of the facts is actually not far away from
dishonesty. Einstein never denied to have read "La Science et
la l'hypothèse". Do you have read this book yourself? Does it
suggest special relativity? And are you sure that noone before
Poincaré ever had the idea that the best way to synchronize
distant clocks is by means of light signals from the center?
The case Einstein-Poincaré is quite similar to the case Einstein-
Hilbert. There is a confusion between

Supérieure des Postes et des Télégraphes. Mars 1913, A. Dumas

Even if Einstein had known 1) it would not have helped him a lot
(see appendix below). Five years ago I wrote on this subject:
_______________________________________________________________________
Anyway, a Lorentzian ether is inconsistent with a consistent
generalization of the so-called Galilean relativity principle
to the whole of physics. Such a relativity principle had been
consistently advocated by e.g. Ockham (1290-1348), Nicolaus
Cusanus (1401-1464) and later also by Immanuel Kant (1724-1804).
So "Lorentzian relativity" is at best a misnomer and at worst a
contradiction.
The classical relativity principle presupposes the inertia
principle (often attributed to Galilei but) advocated at the
latest by Ibn Sina (Avicenna) a millennium ago. Relevant
quotations from Avicenna can be found in:
http://groups.google.com/group/sci.skeptic/msg/0c7a6e19aec6ace0
According to the classical relativity principle as conceived
by e.g. Ockham, Cusanus and Kant, all inertial movements are
equivalent. According to the theory of Lorentz and Poincaré
however, that is obviously not the case. Still in June 1905
Poicaré wrote (translated by me):

So the reproach that Einstein plagiarized somehow a "relativity
principle" from Poincaré does not even make sense. (The question
however, whether Poincaré profited from Einstein's relativity
paper without attribution when publishing his own "relativity
theory" in 1906 could still be open.)

This question is still open:
"D'un autre côté, même si Poincaré n'était pas homme à se mettre
sur le devant de la scène, on se demande encore pourquoi la
communication à l'Académie des sciences de Paris du 5 juin 1905,
«Sur la dynamique de l'électron», reçue en juillet 1905, n'a
finalement été publiée qu'en janvier 1906 dans le Circolo

Think about it, Einstein had a regular work and a family. It was
impossible for him to study all the papers and books that were
published in those days. And how could he have known that the
best candidates for plagiarism would be just Poincaré and Lorentz?

APPENDIX:
Translated extracts from Poincaré, June 1905:
"... It seems that this impossibility of determining the absolute
motion is a general law of nature.
An explanation has been proposed by Lorentz who introduced the
hypothesis of a contraction of all objects in direction of the
motion; ... Lorentz tried to complete and modify his hypothesis
in order to make it consistent with the postulate of the full
impossibility of determining the absolute motion. ...
The essential point, established by Lorentz, is that the equations
of the e.m. field do not change under a certain transformation
(which I'll call Lorentz transformation) and ...
... These transformations, ..., must form a group; however, for
this to be so, it is necessary that l = 1; hence we are led to
assume that l = 1 and this is a consequence which Lorentz had
found by a different way. ...
Lorentz was also led to assume that the moving electron takes the
form of a compressed ellipsoid; ...
... and at the same time [one gets] a possible explanation of the
electron contraction, in assuming that the electron, deformable
and compressible, is subject to a kind of exterior constant
pressure whose effect [travail] is proportional to the variations
in volume. ...
But that is not enough: Lorentz considered it necessary to
complete his hypothesis by assuming that all forces, of any
origin, are affected in the same way by a translation as the e.m.
forces and that therefore the effect of a Lorentz transformation
is once again defined by the equations (4)."
The originals of the translated extracts:
"... Il semble que cette impossibilité de démontrer le mouvement
absolu soit une loi générale de la nature.
Une explication a été proposée par Lorentz, qui a introduit
l'hypothèse d'une contraction de tous les corps dans le sens du
mouvement terrestre; ... Lorentz a cherché à compléter et à
modifier son hypothèse de facon à la mettre en concordance avec
le postulat de l'impossibilité complète de la détermination du
mouvement absolu. ...
Le point essentiel, établi par Lorentz, c'est que les équations
du champs électromagnétique ne sont pas altérées par une certaine
transformation (que j'appelerai du nom de Lorentz) et ...
... L'ensemble de toutes ces transformations, ... , doit former
groupe; mais, pour qu'il en soit ainsi, if faut que l = 1; on est
donc conduit à supposer l = 1 et c'est là une conséquence que
Lorentz avait obtenue par une autre voie. ...
Lorentz est amené également à supposer que l'électron en mouvement
prends la forme d'un ellipsoide aplati; ...
Mais avec l'hypothèse de Lorentz, l'accord entre les formules
ne se fait pas tout seul; on l'obtient, et en même temps une
explication possible de la contraction de l'électron, en supposant
que l'électron, déformable et compressible, est soumis à une sorte
de pression constante extérieure dont le travail est proportionnel
aux variations du volume.
Mais ce n'est pas tout: Lorentz, dans l'Ouvrage cité, a jugé
nécessaire de compléter son hypothèse en supposant que toutes les
forces, quelle qu'en soit l'origine, soient affectées, par une
translation, de la même manière que les forces électromagnétiques,
et que, par conséquent, l'effet produit sur leurs composantes
par la transformation de Lorentz est encore défini par les
équations (4)."

In the case of Einstein-Poincare, the constancy in the speed of light
was already proposed by Voigt a few months before MMX of 1887. In
doing so, Voigt came up with the Voigt transform to adequately explain
the null results of Michelson's 1881 experiment and then MMX itself.
Noticing the Voigt transform fails the principle of relativity, Larmor
modified it to become the Lorentz transform. Lorentz, Poincare, and
Einstein can only contribute interpretations to the Lorentz
transform. Since all the interpretations are based on the Lorentz
transform, there is absolutely no way to show how each interpretation
is more correct or how different from the others. <shrug>
In the case of Einstein-Hilbert, in 1908 after Minkowski had proposed
the concept of spacetime, Klein, Hilbert, Schwarzschild, and Minkowski
himself (the Goettingen group) had started investigating the curvature
of spacetime as the cause of gravitation. Minkowksi died early.
Schwarzschild left for some observatory. The work did not go any
where and was abandoned until 1915.
In the meantime, Einstein being a little bit more challenged mentally
was still struggling to understand Newton's law of gravity. Given him
credit for understanding it, he rediscovered the principle of
equivalence from Newton's law of gravity. The nitwit was almost 300
hundred years too late, for Galileo had beaten Einstein to it.
Einstein never realized Newton's law of gravity is based on the
principle equivalence. After the nitwit Einstein heard about the
Goettingen group's work, he enlisted his classmate Grossmann to apply
the principle of equivalence to the curvature business of spacetime.
Gravity can only be characterized by someone observing how an object
behaves under gravitational effect. Newton did so by observing that
falling apple. Einstein tried to picture himself as the falling
apple. Not surprising, the result was a dead end. Not a single
reference to the field equations is the application of the principle
of equivalence.
After dumping Grossmann and complaining about Grossmann's lack of
progress, the nitwit due to his superb lecture skill or salesman-like
pitch was able to convince the Goettingen group to restart the
research into the physics on the curvature of spacetime. Only after
Einstein had bragged about deriving Mercury's orbital advance after
studying how Gerber did it, Hilbert pulled out the Lagrangian, which
does not even qualify as a Lagrangian, out of his *ss. By taking the
partial derivative with respect to each element of the transpose of
the matrix represented by the metric, the set of field equations is
derived. There is no other way.
Einstein had no influence over the field equations except acting as a
catalyst to force Hilbert to cough them up. I suspect Hilbert had
this all along but was struggling to find the validity of doing so.
Therefore, once again, the nitwit Einstein took no part in
formulations of SR and GR. <shrug>
I agree with Shubee about space and time. That was where Einstein made
his mistake. Everything else is fine: the principle of relativity, the
light
postulate, the explanation of the magnetic force, time dilation and
length
contraction and the transformation equations. When, however, Einstein
interpreted or accepted time dilation and the relativity of
simultaneity to
mean that space and time themselves were not the same for all
observers,
he made a mistake from which physics has never recovered. Indeed, it
has got even worse, by transferring the whole theory, including the
derivation
of the transformation equations themselves, away from Einstein's
original
dynamical basis to the mistaken, static spacetime basis that we see is
preferred today.
This will continue to cause endless trouble for physics, and we may
see
physicists possibly wasting entire careers wrestling, for example,
with the
problem of how to reconcile Minkowski spacetime with the instantaneity
of
quantum nonlocality, until someone discovers that the solution to any
such
problem is to finally recognise and abandon what will turn out to have
been one of the great conceptual errors in the history of science.

That's hard for a lot of people--accepting that space and time are not
absolute but malleable. However, one can't ignore the effects in GPS,
particle accelerators, astrophysical observation such as slowing of
radioactive decay rates and the like.
Fuckin' lunatic.
*plonk*
I wouldn't put forward an argument that suggests they should
be ignored. In other words, the abandonment of Minkowski
spacetime will not involve the denial of any established
experimental results. All that is required is an alternative
explanation that satisfies the experimental results. I believe
such an explanation is possible, and will more easily reconcile
SR with QM nonlocality etc.

I guess you have your sights set on me now?
If I am correct, you are convinced that the Sagnac
effect disproves SR. But I am not convinced that it
does.
Alen
It is hardly ever the case that a theory is unseated by an alternative
theory that has *identical* predictive power, no matter how appealing
it may be in the mind of the proposer.
This little criterion is one that hobbyists on this group routinely
overlook, or when it is pointed out to them, don't care for.
PD
That argument is ok, all things being equal. In the case of
Minkowski spacetime, however, which is illustrated by the
corresponding spacetime diagram, the specification that
length contraction exists, whatever the method used to
measure a moving length, can be disproved. The reality is
that length contraction exists only when a moving length
is measured by sending a light ray along it, and not otherwise.
The spacetime rotation model for inertial frames cannot specify
this restriction. This means that the Minkowski spacetime
model cannot be correct, and this is what necessitates an
alternative explanation.
Alen
That is experimentally incorrect. You need to take a look at rapidity
distributions of particles in fixed-target and collider experiments,
where there is no light sent anywhere.
Familiarity with experimental evidence is so crucial to physical
understanding that a lack of the former prevents the latter.

The "history makers" have gone to great length to promote a nitwit
(Einstein) into the greatest mind through out the entire human
history. However, for the first time, yours truly has pioneered this
field of forensic research through mathematics. Sorting through
pieces of actual historical accounts and applied with appropriate
mathematics to cross check the validity involved, it allows yours
truly to straighten out what exactly happened in this particular event
in history involving Einstein the super nitwit. <shrug>
Just imagine how other historical accounts are also distorted, made
up, and lies. Most of them cannot be cross-checked by mathematics.
Actual history making seems to be what modern history is all about.
It can easily be covered up with peer pressure, over self-esteem,
stupidity, and lack of rationality. <sigh>
I am already aware of that, and have been given that answer
before. The length contraction of charged particles does not
make what I have said to be experimentally incorrect.
The possible working of photons within the fields of charged
particles cannot be positively excluded from the length contraction
effect in the case of high velocity particles. They cannot
therefore be taken as experimental evidence against what
I said. Even in the case of neutral particles, if any such
evidence exists for neutral particles, lightspeed bosons in
their gravitational fields could be working in the same way
as photons.
The argument I have put forward against length contraction
in the absence of light is incontrovertible, and will not be
contradicted by any experimental evidence.
