Default DO RELATIVITY ZOMBIES UNDERSTAND RELATIVITY HYPNOTISTS?

The "Lorentzian form of relativity", reduced to its essentials, is:

One can easily show mathematically that A+B imply C.

Hang on .. let me see

If we have three objects at rest in three inertial FoR A,B,C and we have
(say) that A is at rest relative to the 'ether' FoR, B is moving at
velocity v relative to A, and C is moving at 2v relative to A. So
according to premise A) and B) above, an object A has no length
contraction or time dilation (because it is stationary in the ether
frame), object B has some, and object C has more. So an observer in FoR
B would see objects in A as expanded and objects in C as contracted.

This is not true, basically because "length contraction" and "time
dilation" are not the entire story, and there is also "relativity of
simultaneity", and all 3 interrelate with each other.


I understand all that in terms of Lorentz transforms as part of SR ..


You don't. Consider carefully Master Tom Roberts' wisdom:

http://groups.google.com/group/sci.p...2471a17131c4b?
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)."


Curiously Tom Roberts' theory (plagiarized from Jean-Marc Levy-Leblond
and possibly other relativity hypnotists) according to which if light
in vacuum does not travel at the invariant speed of the Lorentz
transform, special relativity would be unaffected, does not seem to be
very popular in Einstein criminal cult. Perhaps cleverer hypnotists
feel that Tom Roberts' theory is too silly to be used as camouflage.
