There is a new(?) theory that the speed of light was faster at the dawn of the universe.

That's a pretty old theory and except for a few people who resurrect it once in a while, I thought it died a slow death. It was first looked at in 1937. Here's a reference....

"Vacuum" simply means absence of AIR. So pretty much any transparent medium can slow down the velocity of light........glass, water etc, which in fact is nothing more than change in the direction of light!!!!!!!!
And the theory that the speed of light was faster "at the dawn of the universe", is there an explanation to this theory?

If something is in a vacuum to slow light, it isn't a vacuum any more....

Only something with an index of refraction can slow light. A black hole can suck it in, but that's not really slowing it.

New theory....The speed of light is constant. It is infinite. It is the speed of our senses that "slows it down".

Not.
This is impossible
