Reply to comment by majorpickle01 in has the speed of light always been constant? by 2bornnot2b

My level of physics is limited to what I understand on the side because of my math major, but I have a question:

If speed of causality changes, would we even be able to measure that? Or what the change in causality cancel in all of our measurement instruments to give the same result again?

from the very limited reading I've seen into the subject the idea is it would be detectable in the CMB - something along the lines is it would affect the distributions of bands or something like that.

If you do some digging for papers on it there's are suggestions on how to test for it / physical consequences
