If this should be in the cosmological section, then i don't mind to see it moved, but since it appears to be an abandoned theory, i'm posting this in the classic physics section. I was talking to a religious person, and he was claiming that the big bang theory was.... wrong, that it had been "debunked", and that the steady state theory was probably correct. Now, i'm a master student of physics, and i can't remember learning more about the steady state model than it being mentioned as a footnote of a theory that turned out to be incorrect during the 60's. Since then i looked it up at Wikipedia: http://en.wikipedia.org/wiki/Steady_state_model But can anyone give me additional information on it? I've never actually met a physicist who uses this model to-day. Mind you, the guy i'm talking about is of the level of high school education, and only knew about it because it was more compatible with the Bible.
