Hi
I am in a debate with some creationists. They are claiming that the speed of light changes in strong gravitational fields and can be slower or faster.
My view is there can be time dilation effects. For example light towards the centre ( a black hole ) will be red shifted, and away from the centre will be blue shifted. But the speed of light is unchanged.
The time dilation would make things appear slower, or faster. A satelite falling into a black hole would seem to take forever.
I have tried googling but I cannot find any good links to that. The closest was
http://arxiv.org/ftp/physics/papers/0611/0611294.pdf
But I feel that is somewhat ambiguous, as in one place it is saying it constant, whilst saying that there is a theoretical case where it may change
What are people's thoughts?
Thanks in advance
George
