I've been watching too much science channel specials on black holes and need a few things cleared up heh On the TV show they said that a black hole is actually not only eating near by stars and gas but actually consuming space time its self. My question is, if space time is being sucked into it at speeds faster then light, how is the graviton force particle able to escape. Do gravitons move faster then light? Another question I have is about super-massive black holes. Some black-holes like the ones in the center of galaxies are billions of solar masses while others are only 10. On TV they said that the singularity is infinitely small and infinitely dense but if this is the case is one infinity is bigger then the other one?
