Black Holes

have black holes actually been proven to exist? when i was a kid i was all into astronomy and recently i've been looking into it again, and after reading several articles on the subject im still kinda in the dark. if you say wiki black holes there's tons of inferential information about them existing but no references to actual known black holes. also I just read some random post on /b/ (lol, reliable information) saying "as science has proven a blackhole is impossible (NASA news 2006) " <- anyone know wtf article he's referring to.

so tl;dr, blackholes: definately out there or an interesting theory?

let me explain this
black holes means they are black>means you cant see them
we can see the effect of them on the surounding space so we know theyre there
but unless your gona let me throw you into the core of the black hole and you can take a picture of it(not likley) we cant definetly prove they exist
option 2 wait for a big enouth star to supernova and then wach the fireworks as it colapses into a black hole
