Black holes are not real. They are a mathematical absurdity that should have been taken as a demonstration of a flaw in the theory, or a flaw in translating the mathematics into actual physical reality.
Actual physical things don’t deal in infinities, as black holes do.
Black holes don’t really deal in infinities. That’s only where our knowledge of mathematics indicates that our knowledge of physics falls short.
There’s a picture. They are very much real.
Black holes are real. Maybe you missed the news from a couple weeks ago, but scientists have directly imaged one now.
