"Albert Einstein’s postulate "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" [1] is one of the pillars of modern
physics. Modification of this postulate would have far-reaching
consequences for our understanding of nature, it is therefore
important
to constantly improve the verification of its validity. Particularly
in the past few decades, a possible energy dependence of the speed of
light has been predicted in the framework of quantum gravity models
[2, 3, 4] and effective field theory [5], leading to deviations from
this postulate (for reviews see [6, 7, 8])."

The "far-reaching consequences":

Albert Einstein: "If the speed of light is the least bit affected by
the speed of the light source, then my whole theory of relativity and
theory of gravity is false."

Albert Einstein: "I consider it entirely possible that physics cannot
be based upon the field concept, that is on continuous structures.
Then nothing will remain of my whole castle in the air, including the
theory of gravitation, but also nothing of the rest of contemporary
physics."

Einsteiniana' hypnotists trying to both camouflage the problem and
calm the panic (note the conversion of the dangerous "frequency-
dependent speed of light" into the toothless "time-dependent speed of
light":

Joao Magueijo: "In spite of the strong reactions they elicit [8–10],
VSL theories may be nothing more offensive than non-trivial
realizations of the Lorentz group......The cosmological redshift acts
to convert a frequency-dependent speed of light into a time-dependent
speed of light. This idea was already recognized in [21], in a
different guise. If the speed of massless particles increases with
energy, then the fact that the 'average particle' has a higher energy
in the early universe means that the 'ambient' speed of light is also
higher."
