Quantumist:

Thats just not true guy.. The universe is expanding ..and its expanding at an ever increasing rate. The more it expands the faster its expanding..

There is a view that at some point the total mass will hit a point where the expansion stops and it starts to compress but there is absolutely no evidence that that is happening. This view is based on the observed mass and a model that says that at some point the total gravitational effect across the universe will stay the same but the energy converted into kinetic (and other forms) at the time of the BB will decrease untill the gravity overall over powers the energy imparted to expand...

But the existing body of evidence shows a ever faster expansion rate. Goggle the COBI observations to get a bit of insight on the present understanding of the construct.
The evidence shows there's not enough mass for recontraction.
natureisawesome Reviewed by natureisawesome on . wtf happened before the big bang? i was high one day and was thinking about the big bang and stuff. and thought what happened before the big bang? scientist always talk about the big bang and everything that happened after that, but none talk about before the big bang?
