"Research on 'relativity violations' is reaching fever pitch, with the
number of manuscripts on the subject up ten-fold from a decade ago,
physicists heard at the American Association for the Advancement ...

Falling at light speed is the very problem of extreme gravity.
Some wish to avoid it by rationalizing that it doesn't happen.
It does happen in black holes. There is no way of avoiding it.
Try as you might.

Experimentalists are allowed to publish information about superluminal
signals if and only if they also admit that no superluminal signal, not
even those four times faster that the speed of light, can damage
Einstein's theory:

Modern astronomy is based on the assumption that all starlight in the universe
travels to little planet Earth at precisely 'c'.
I wonder what magical power arranged for this to happen since in many cses,
Earth wasn't even in existence when the light left its source.

Magnetism:
1.EM Radio(photons) waves don't cancel each other out, the momentum
remains.

Albert Einstein, "Relativity", Chapter 22 :
"In the second place our result shows that, according to the general
theory of relativity, the law of the constancy of the velocity of light

1 Ptolemee considered, that reference frame connected with the Earth
is absolute.
2. Copernicus proved, that reference frame connected with the Sun
 is absolute.

relativity is doomed kaput for good now
take this paradox i dicovered five minutes ago
if ether is not needed by anything as thay says,
than empty space cannot be curved, becus in

okay, geodesic paths are bery nice,
but whay are thay circular, whay
is tha eart revolving and rotating
whay is tha moon not rotating

Einstein derived the concept of Relativity of Simultaneity (RoS) using the
train gedanken. He  said that the track observer sees the lightning strikes
to be simultaneous because he is not moving wrt the light fronts from the
strikes and that the train observer sees the strikes to be ...

Are you one of these physicists Smolin is referring to? What do
you say about it.
Lee Smolin has this to say about GR:
"As it happened, general relativity already existed, but - and this

I haven't been able to understand how this is explained from the point
of view of a moving observer.  I asked a similar question before but
did not get a clear answer.
Here's the problem.

In 1919 Karl Popper found it suitable to start worshipping at the
portrait of Albert Einstein because, unlike Marxism and psychoanalysis,
the theory of relativity produced unambiguous results that could be
tested experimentally. I suspect Popper was particularly impressed by

It is interesting to note what Einstein himself said about an ether:
