It ends up right there, in the black hole. It gets compressed down until it's so ridiculously small and dense that, even if you could somehow get it out of the black hole, you'd never be able to figure out what it was before it got sucked in. It becomes part of the black hole, which isn't really a hole but a collapsed star whose gravity is so intense that it sucks up everything including light.
