Hi, Callisto! Belated Happy Birthday!!!
Hi 3rdworld! Welcome to UT! About blackholes, well, I guess, relevant facts were already given here. There rest are, at the most, intelligent guesses based on scant info about blackholes. Where does something that is sucked in a blackhole go? Nobody has evidence that it leads to somewhere else but we have proof that it emits something like jetstream of particles. It could be that what is sucked became a part of it. You're young. I hope your curiosity about blackholes remains as you grow old.
