Default SPECIAL RELATIVITY WITHOUT THE LIGHT POSTULATE

Tom did not discover that - it is a simple consequence of the fact light can
be modelled by, for example, the Proca equations, with a very small mass
instead of the usual one, and be in agreement with all current evidence,
provided the mass is taken as small enough.

Tom Roberts: "if it is ultimately discovered that the photon has a
nonzero mass (i.e. light in vacuum does not travel at the invariant
speed of the Lorentz transform), SR would be unaffected but both
Maxwell's equations and QED would be refuted (or rather, their domains
of applicability would be reduced)."


I thought initially Jean-Marc Levy-Leblond discovered that, even if
"light in vacuum does not travel at the invariant speed of the Lorentz
transform", "SR would be unaffected":

Jean-Marc Levy-Leblond: "The evidence of the nonzero mass of the
photon would not, as such, shake in any way the validity of the
special relalivity. It would, however, nullify all its derivations
which are based on the invariance of the photon velocity."

Are time dilation and length contraction "derivations which are based
on the invariance of the photon velocity"? More questions could be
asked but neither Tom Roberts nor Jean-Marc Levy-Leblond nor any other
hypnotist in Einstein criminal cult would ever answer. Only bellicose
zombies will continue to defend "special relativity based on the light
postulate", "special relativity without the light postulate" and, if
necessary, "special relativity both with and without the light
postulate".

If all that surrounded you suddenly was in motion through time at a
much slower rate, then you may see a baseball passing by you at an
incredibly slow speed. If you try to alter its path of motion, it
will take a large amount of energy to do so. It will give the
appearance as though the baseball's mass is much larger than expected.

If a baseball was in motion across space at a high velocity, it would
also be in motion across time at a slower rate since clocks a ticking
at a slower pace in its new frame. Here to if one tried to alter its
path of motion it would seem as though its mass had increased due to
its slow motion across time.

All matter is constantly in motion in Space-Time. The only change that
can occur is the change of direction of travel in Space-Time.

If a meson is at rest in space, then its constant motion is now
confined to being across Time only. If the meson then breaks down and
splits into two photons, then these photons will fly apart from each
other, and each will travel across space at the speed of light.
However, since the meson was in motion across the dimension of Time,
the photons too are also still flying across the dimension of Time
even though they also are in motion across space.

As the result of this, there is no simulation of an increase in mass
of each of these photons even though they travel across space at the
speed of light.
