"The true scientist must have faith and believe
in the scientific method of testing theories, and
not in the theories themselves.

It isn't a faith it is a dicipline.

It isn't a dicipline, it's a discipline.

Good post, but does a relativist take the position
that "absolute quantities cannot be defined"?
Doesn't any invariant quantity qualify as an absolute quantity?

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.
