The speed of light also appears to slow down, as one approaches the Big Bang in a recent study of black holes.

Huh?

[MacDorcha]

ill take a stab at the long hand of it for ya.

light is something that travels and is measured in relation to other things. the universe, in the big bang theory, is always expanding, and slowing down as it does so. light, being part of the universe must also be slowing down, as the limits of this plane are reached at lower speeds, since the universe cannot sustain constant expansion (hence, the big crunch theory, which even while some in here support it, neglect that aspect of the arguement) everything in it must slow down before coming together again. get it?

I misspoke. The spped of light speeds up as one approaches the Big Bang. The implication of this is that our calculations of the Big Bang having occured 13 billion years ago may be an illusion.

"Australian theoretical physicist, Professor Paul Davies, has proposed that one of the so-called “constants” of the universe – the speed of light – has in fact slowed over time, a revelation that will cause a rethink of many of our accepted laws of physics as well as our “understanding” of the beginning of the universe. Davies’ paper, Black holes constrain varying constants, is published in the August 8, 2002 edition of leading science journal, Nature."
