Black holes have a lot of evidence in favor of them but there is still debate as to their possibility. The evidence in favor is called Einstein rings. This shows that space itself can bend and bend the path light takes, the rings being light from a way distant galaxy say 10 billion light years away but exactly between it and us is another galaxy, say at 5 billion ly away.
So being half way like that, the light from the distant galaxy is magnified, bent around the intervening galaxy and comes to us way distorted like a ring or an arc and astronomers can gain information about that distant galaxy that we couldn't have gotten if the intervening galaxy had not been there.
That closer galaxy becomes like a giant telescope lens and it is the gravitational field of the entire galaxy as a whole that bends space enough for us to see that even further galaxy.
What that means is if the mass of a collapsing star condenses enough, it more or less makes a hole in our space-time continuum and like a cockroach hotel, you can check in but you can't check out, not even light can escape, since the escape velocity would be greater than the speed of light so even photons are trapped.
They have images that have been analyzed that suggests there is no other explanation for what they are seeing.
The LHC in Cern is thought to be powerful enough to eventually create a tiny tiny black hole and one of the theories about black holes is the smaller they are the shorter they live before they uncollapse and make a reverse black hole, a white hole which spews out all the energy that was sucked in when it was made.
So the ones at LHC if they succeed, would be so tiny they would blow up in microseconds or less and the particles that come out would be proof black holes exist, solid scientific proof. As of now they have observations that supports the black hole idea but of course we have none in the vicinity to send a probe to so it is still open to debate. All that debate would stop cease and desist if LHC actually makes one. It is proven the lesser bending of space actually exists because of Einstein, he predicted them and they were found. Dramatic photo's of rings. I'll try to find a link.
Here is one, a black and white image from Hubble showing not one but a double ring!
Here is a bit on black holes:
