Do you feel that the Big Bang really happened…? Yes.
…or is there another explanation as to how our universe began? Maybe.
Will we ever be able to determine the exact shape of our universe…? Yes.
…[is it] finite or infinite? Yes.
Will science be able to answer the question of whether there is a God or not? No.
I just like the large-busted, half-undressed women on the covers.
What? Oh, that’s Cosmopolitan. Crap.
Anyway:
I think the last three or four decades of astrophysics, incuding the discovery and measurement of the cosmic background radiation and increasingly accurate redshift measurements leave little doubt that the Big Bang or something very much like it occurred. As to where it came from, I’ll leave to the big thinkers.
I think so.
Assuming that it is interacting physically with our universe, yes. Assuming it works only by magical powers, no.
