Perhaps new aetherists and old relativists have decided to elaborate
on the silliest text in the history of science - Chapter 7 in
Einstein's "Relativity":

http://www.bartleby.com/173/7.html
Albert Einstein: "For, like every other general law of nature, the law
of the transmission of light in vacuo must, according to the principle
of relativity, be the same for the railway carriage as reference-body
as when the rails are the body of reference. But, from our above
consideration, this would appear to be impossible. If every ray of
light is propagated relative to the embankment with the velocity c,
then for this reason it would appear that another law of propagation
of light must necessarily hold with respect to the carriage - a result
contradictory to the principle of relativity. In view of this dilemma
THERE APPEARS TO BE NOTHING ELSE FOR IT THAN TO ABANDON EITHER THE
PRINCIPLE OF RELATIVITY OR THE SIMPLE LAW OF THE PROPAGATION OF LIGHT
IN VACUO. Those of you who have carefully followed the preceding
discussion are almost sure to expect that we should retain the
principle of relativity, which appeals so convincingly to the
intellect because it is so natural and simple. The law of the
propagation of light in vacuo would then have to be replaced by a more
complicated law conformable to the principle of relativity. The
development of theoretical physics shows, however, that we cannot
pursue this course. The epoch-making theoretical investigations of H.
A. Lorentz on the electrodynamical and optical phenomena connected
with moving bodies show that experience in this domain leads
conclusively to a theory of electromagnetic phenomena, of which the
law of the constancy of the velocity of light in vacuo is a necessary
consequence. PROMINENT THEORETICAL PHYSICISTS WERE THEREFORE MORE
INCLINED TO REJECT THE PRINCIPLE OF RELATIVITY, in spite of the fact
that no empirical data had been found which were contradictory to this
principle. At this juncture the theory of relativity entered the
arena. As a result of an analysis of the physical conceptions of time
and space, it became evident that in reality there is not the least
incompatibility between the principle of relativity and the law of
propagation of light, and that by systematically holding fast to both
these laws a logically rigid theory could be arrived at."

So Einstein saved the principle of relativity prominent but silly
theoretical physicists wanted to reject, resolved the deep crisis
physics was in and built the miraculous modern physics we enjoy today.
However now that the miraculous modern physics is in a deep crisis, it
may prove profitable to reject the principle of relativity after all.
One thing is su THE SIMPLE LAW OF THE PROPAGATION OF LIGHT IN
VACUO:

http://www.fourmilab.ch/etexts/einstein/specrel/www/ "...light is
always propagated in empty space with a definite velocity c which is
independent of the state of motion of the emitting body."

should NEVER be rejected, no matter whether it is false or not. Both
new aetherists and old relativists feel that, without this simple law,
their money-spinner will be irreversibly destroyed.
