ScienceDaily (Oct. 6, 1999) — A University of Toronto professor believes that one of the most sacrosanct rules of 20th-century science — that the speed of light has always been the same - is wrong. Ever since Einstein proposed his special theory of relativity in 1905, physicists have accepted as fundamental principle that the speed of light — 300 million metres per second — is a constant and that nothing has, or can, travel faster. John Moffat of the physics department disagrees - light once travelled much faster than it does today, he believes.

Recent theory and observations about the origins of the universe would appear to back up his belief. For instance, theories of the origin of the universe — the “Big Bang”- suggest that very early in the universe's development, its edges were farther apart than light, moving at a constant speed, could possibly have travelled in that time. To explain this, scientists have focused on strange, unknown and as-yet-undiscovered forms of matter that produce gravity that repulses objects.

Moffat’s theory - that the speed of light at the beginning of time was much faster than it is now - provides an answer to some of these cosmology problems. “It is easier for me to question Einstein's theory than it is to assume there is some kind of strange, exotic matter around me in my kitchen.” His theory could also help explain astronomers’ discovery last year that the universe's expansion is accelerating. Moffat’s paper, co-authored with former U of T researcher Michael Clayton, appeared in a recent edition of the journal Physics Letters.

Of course, it's all theory and I don't even qualify as an amateur physicist.

Same here. I wonder though if “old” light may be tired, but fresh “new light” has plenty of get up and go. And does “old light” get a boost if you shoot it full of “new light.”

And, the Big Bang thing has always bothered me. It’s like science has to keep adding new things to support it, like dark matter, dark energy, and mass transit.
