These backward-moving radiation are called "advanced waves" whereas the ordinary radiations are called "retarded waves."
Do any of you physics people know anything about this? Is it really possible that stars can absorb their own light if the universe ever begins to contract?
I think the finding that the universe is not only expanding, but that said expansion is accelerating makes the contraction hypothesis problematic, at best.

"In short, Meyer has shown that his first disastrous book was not a fluke: he is capable of going into any field in which he has no training or research experience and botching it just as badly as he did molecular biology. As I've written before, if you are a complete amateur and don't understand a subject, don't demonstrate the Dunning-Kruger effect by writing a book about it and proving your ignorance to everyone else!
