Q:
Do you think it is possible that light may be slowing down over a period of millions of years? Recently I read an article with a scientist in Australia was working to prove this.

A:
A change in the speed of light would make the laws of physics more
complicated. Most physicsits don't think that it's very likely, but no
one knows for sure. Some recent astronomical evidence has been alleged
to support the idea that the speed of light is changing, but the
evidence so far is very weak.
