: : Nothing escapes from a black hole. Conditions prior : : to the big bang were, by all accounts, an extreme case : : of black hole. So how could the big bang result in : : expansion?

: I just started doing some calculations on the size : of a black hole containing all the matter in the : universe. I made very low estimates of average : mass of a star, number of stars in a galaxy etc : and didn't add the black matter. My first result : was an event horizon over 10^7 light years radius.

: What bothers me is, the gravitational force froze : out long before the universe was this big, so how : could it have expanded?
