[QUOTE="Umbran, post: 5311169, member: 177"] You should be able to actually say: if it has significant spin, the event horizon will not be perfectly spherical. Like planets, it should be be slightly "oblate" - a little pressed in at the poles of spin and fatter at the equator. At least so says the math. The density. The asymptotic slowing of clocks as you approach the event horizon. Classically speaking: If you're out here in the rest of the fairly normal universe, it takes "forever". If you're the one falling, it takes as long as it would take you to fall, like you were falling anywhere else. Quantum mechanically speaking: As above, but there might be a chance for you to "tunnel" through the event horizon at some point. The chance of you tunneling through should increase the closer you are to the horizon - and there's never certainty that you will pop across the barrier. So, maybe forever, maybe some absurdly long time. Given that we've only ever observed these things at great distances, and don't have an adequate theory of how gravity and quantum mechanics work together, we cannot say with absolute surety. We can only speak by way of current understanding. Actually, it does. If it isn't infinitely dense, if there is some force that does keep it from complete and utter collapse, you don't get an event horizon. Existence of such a force would imply the existence of something that can escape the grip of the object's gravity, and the hole is no longer "black". This is why we often say, "until the end of time" - whatever end that might be. Mind you, brane theory is not tested (and so far is untestable) and not widely accepted - and depending what version you're talking about, our universe and our brane are not equivalent. [/QUOTE]
