"every one can relax, Gambit has returned"

no pointless replies. i understand that c is the symbol for the speed of light. my question is:

Is c, the speed of light in vacuum, constant?

this is such a complicated matter. not my field.

i am doing research and would like to hear from "scientific" minds on this subject. don't waste my time. post only if you have supporting facts.

They sped up light in a Vacume, and slowed it down. So light is not constant in a vacume.

There is a theory that in the early universe, the speed of light was different. Get this book if you're interested:
