Hi all, this is my first thread so be nice.
Ok, so I remember reading something which said that if an astronaut falls into the event horizon, his vantage point of time will slow down (due to the massive gravitational field) and will eventually halt at the event horizon. He will therefore see the fate of the universe--if he lives through this of course. My problem is the following: this seems to imply that matter will never ever fall into the event horizon (which i know is not true), and if not, how do black holes consume matter and increase in size (such as the ones in the center of the galaxy). Since that can not be the case, what have i misinterpreted here? Please help.
Another problem, sorry for the length! I seem to be suffering from the same confusion as this poor man: http://superstringtheory.com/forum/basicboard/messages3/63.html His point is, how do blackbodies radiate a continuous sprectrum of energy when matter, when excited, radiates only spectral bands peculiar to the matter. What is the mechanism of blackbody radiation?-- as opposed to the mechanism of emmission (electron excitation).
