so far as i can tell from reading about it, the theory involving the brane (string theory) did not discard the big bang, just it points to how it occured.

if you have any referece to where people are saying that the big bang did not happen, please post them. the one i read said that it was a reoccuring event, happening every so often (if i remember correctly, something on the order of 100 billion years or more). that theory did not destroy the big bang theory, merely changed a bit.

the more man learns, the more he realises, he really does not know anything.
