C is a constant. I promise it is a constant. If it weren’t constant, the energy bands would be different in distant spectra. c has been measured to be constant for at least 13 billion years.

Very true… I kind of get it..Thought experiment..
Let say I’m light at the first moment in time..The Big freaking big bang…
Light’s speed is zero.. So now everything expands… As the universe expanded did light slowly speed up with the expansion? or at just at a certain point was it able to escape mass as a c constant?
That math interests me…I’d like to learn more…
But if light escaped at the speed of c that means we will never be able to see the expansion period with telescopes..There was no light to seen..But if there was a variable speed of light in the beginning to obtain c..( Like a race car speeding up from the pits to a final speed) Then there is hope to see some light during the expansion period looking back in the future…
What do you think Lud?
