See? That's the trouble with you kids. They spotted something with telescopes, and decided they were going to call them black holes. The fact is, they don't really know what they spotted.
ROFL. You really dont have a clue, do you? Here is what really happened: einsteins equations of special relativity
predicted there would be black holes, even though that seemed insane at the time. It took years to figure that out and understand and decades more to actually find evidence that proved their existence. Thats how science works: you formulate a theory, then figure out ways to prove or disprove the theory. If you can not prove or disprove it, its not science. BTW by now the evidence is overwhelming, from lensing effects to the gravitational pull they exert on nearby stars and entire galaxies. No one sane doubt they exist.
BTW bis, you cant see a black hole with a telescope. Duh.
