does anyone know anything more on this. I dont know much about anything, so its hard for me to grasp.
Was the scientific creation of black holes a guess based on what we know about physics, and we happend to be correct? Or are you suggesting that we created them?
I have an open opinion either way, and im curious about other views.

After Einstein came out with his theory of General Relativity, a man named Karl Swartzchild realized that it predicted the existence of a yet undiscovered object (the term "black hole" would be coined years later).
He realized that, because light is affected by gravity, it would be possible for an object to have so much gravity that light would not be able to escape it. He also realized that, because the gravitational force of an object is in some ways dependant on it's density, any object could become a black hole if sufficiently compressed. The radius at which an object will become a black hole is called the "Swartzchild radius".
He sent all this to Einstein who said that, although it was an interesting interpretation of his theory, he didn't think such an object could actually exist. There was some debate as to whether a collapsing star could collapse so far as to become a black hole. For quite a few decades most people thought that black holes were just a theoretical oddity.
Then eventually we started to see actual evidence of black holes.
So it's not that the theory "created" black holes - just that the theory predicted their existence long before most people could accept their existence.

Once, men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them.
