i dont need more copy-pastes from google, and there is nothing more to say about black holes since they cant be explained with our laws of physics.
Real black holes are not visible by human eye except some cases.
Black hole is only visible via gravitation results.
two different statements in a single text? and no there isnt a way to see a black hole, you can only spot it, obviously you need to find a better source next time :)
enough from me.
