: 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? |
