Or in other words, a black hole is something that light never escapes from, and the universe is also something that light never escapes from. Ignoring hawking radiation of course... ... unless the cosmic microwave background is the equivalent of the hawking radiation given off by black holes (note: for the picky, before you object, consider that hawking radiation consists of when one part of a short lived mutually annihilating pair of particles falls into the event horizon and the other falls out (hence gets radiated away) and thus from the point of view of those inside the black hole it would appear as those there was a constant rain of particles falling in... which I'm equating here to the microwave background noise), which would imply that our universe is shrinking... ...unless it implies that our universe is getting bigger, maybe if our universe is a black hole with hawking 'radiation' then on the other side of the 'universal event horizon' things work a bit differently and it is matter which is more likely to fall in, not anti-matter... ... which would explain why baryonic matter in this universe has an overwhelming tendency towards matter instead of anti-matter, which is one of those really big still outstanding questions in science...
