By the way,
here's the parent page for the one where I think you got your quotes about red shift.
Two things scare me about that:
1) This is a page put together by a professor at the University of North Carolina. Even if he is writing outside of his field (no education in biology, physics, or cosmology) it is pretty bad.
2) This is a Web page owned by a professor of
computer science. Hopefully the fact that it was apparently coded in 1994 isn't indicative of the currency of his teaching.
