variable c
	Pardon me...I should have reported the variable G statement as 
conjecture rather than fact.  Dirac suggested it, and there has been some
recent (circa december 1980) evidence in favour of it.  I have seen these
results in several places, but unfortuantely th only one that I can remember
is in Expanded Universe, which (all due respect to RAH) is not a definitive
source.  Sorry.
	As for the conjecture of a variable c, it was suggested here that
c is some function of the curvature of spacetime, which, agreed, implies
preferred reference frames.  A correspondent at pur-ee!purdue!pur-ph wrote
privately to say that in fact it was a well-known result of general relativity
that light speeds up in the near neighbourhood of a star - which (I think)
is precisely what I suggested might be the case.  Of course, I might
have missed the point entirely.
	Comments?
