The Big Bang Vs. the Big Rumble
WBUR radio in Boston hosts a talk with two physicists, Alan Guth and Neil Turok, who represent, respectively, the consensus theory of the inflationary Big Bang and an upstart theory of the initiation of the universe in the collision of two three-dimensional "branes." Turok and Paul Steinhardt developed their "Ekpyrotic proposal" out of the mathematics behind string theory. In the audio the two physicists are perhaps more respectful of one another's views than the host wishes them to be. If you ignore the "let's you and him fight" framing of the debate, you will hear some interesting physics elucidated.
You see theoretical scientists (you know the ones that have been working on stuff for decades and still don't have a single experimental piece of evidence) like to make up terminology and throw around big scary formulas to justify wasting time and money working on stuff that cannot even be proven experimentally. Sorry for the bitterness, but I wouldn't even call these people scientists. They might as well say that a giant spaghetti monster flies around and his noodly appendages form tiny knots and those knots are the elementary particles....BUT...OMG! the appendages are so thin that we cannot experimentally detect their presence...but they are there, trust us, here is a big hairy formula (don't worry about the solutions for know) it proves everything -- Give us another PhD!
Actually nothing has been 'proven' with regards to the beginning of the Universe. Everything is still theory, and while significant holes have been blown in the ekpyrotic model, I've no doubt that the 'real truth' if ever found will probably look significantly different from either the Big Bang or the Ekpyrotic model.
