c is an invariant quantity. It is however not absolute to all
frames, for all paths that light can take. Only to local frames
is it invariant. Alpha serves to similarly tie down the other
big "invariant quantities".

Absolutes available then appear to be: death, taxes, and trolls
on sci.physics.relativity.
