   Why do people always think I’m crazy? There is? no proof of Black Holes. It’s not a theory. I’m not on drugs, you’re on drugs, you can’t spell ‘off’

   Actually, there is evidence. There is not concrete proof. There is evidence of atomic structure, and gravity and the like. A real scientist knows that we base decisions on the best evidence. We had evidence of holes in the periodic table that allowed us to guess elements we had not found yet. The same applies to our theory of black holes. Thank you mr. hawking.

    There actually is proof of black holes James. search google for “Detecting Black Holes” and as for the video? Excellent! Very well done! I enjoyed it!

    There isn’t proof of black holes, there is proof of EVIDENCE OF black holes. You cannot prove the existence of black holes because of the very nature of them. We can only define what we think may be a black hole by its surroundings and how they operate.

    if there arent black holes how do some of these things happen?

    We don’t know, which is why the THEORY of black holes is a plausable one. See how that works?

    majority of theories scientists come up with are bullshit because they have no other way or better explanation for most things so they come up with something that is totally false but somehow is vague so no one can argue with it. it is all bs
