I was watching a DVD recently in which a Christian physicist was discusing red shift. Red shift is typically used by astronomers to give the distance of a star or galaxy from the earth. Everything was supposed to have originated from a big bang, and spread out from the centre of the explosion. It was believed red shift confirmed this assumption. An astronomer by the name of Arp has found big differences in red shift of stars in the same galaxies. If correct, the findings will destroy one of the foundational assumptions of the Big Bang Theory.
