"Out-Einsteining Einstein. General relativity is one of the great
triumphs of 20th-century physics. So why does this physicist want to
fiddle with it?....John Moffat is not crazy. It's important to mention
this, because many of those who claim to have improved on Einstein's
theory of gravity, known as general relativity, probably are. Or if
not crazy, at least misguided. Their error-riddled and often
incoherent papers land regularly on the desks of physics journal
editors (where they are promptly discarded or filed under "cranks")
and clog certain corners of the Internet. But Moffat is, in fact, a
respected physicist. Born in Denmark, he earned his PhD from Cambridge
and taught at the University of Toronto for more than three decades
before moving on to his current position at the Perimeter Institute
for Theoretical Physics in Waterloo, Ont."

Absolutely correct. Nowadays crazy and misguided Einsteinians are all
looking for Lorentz violations and if it were not for Moffat's (and
Magueijo's) sanity they would have found some:

Joao Magueijo and John W. Moffat: "The question is then: If Lorentz
invariance is broken, what happens to the speed of light? Given that
Lorentz invariance follows from two postulates -- (1) relativity of
observers in inertial frames of reference and (2) constancy of the
speed of light--it is clear that either or both of those principles
must be violated."
