: : Such as ?

: : One question which I've been thinking about : recently is, assuming there was an initial 'big : bang' (and that's a topic in itself), then how : long did it last. I can put forward an argument : for two, it lasted time zero, this idea : has alot going for it and fits in with a 'cosmic : switch' theory that I have. The second idea is : that it lasted a small undefined amount of time, : which directly relates to the amount of matter in : the universe and lends itself to a finite universe : theory.

: I'd be interested to discuss this, I've never seen : any mainstream data on this, presumably because : no one knows yet.

I've recently heard Neil Turok (who works closely with Stephen Hawking) state that he believes the universe began from a tiny particle that spont- aneously expanded and evolved into what we know as the universe. This is expected to have happened in a very short time frame.
