@33Ohms you cant directly see a black hole, they are invisable. And yes you a correct, due to their intense gravitational field strengh nothing can escape them not even light and debatably not even time, but the way that an astronomer can view a black hole is by looking into the night sky and searching for a distorted patch of sky. The distortion is caused by a black hole's gravity trapping any and all of the energy and matter in its way.
@Devonmeister
Kinda right but kinda wrong in the same sense...you WOULD be able to see the jets of matter and light form around the accretion disc...which makes black holes somewhat visible in the light spectrum...however...if nothing has gotten caught in the tidal forces of a black hole then yes you are correct...you would not be able to see it...
