: : : : 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?
