You are still acting as if humans know everything in the universe

No, but seriously, we don't know exactly what black holes are exactly cuz no-one can get close enough to find out. Technically, if black holes are what you think they are, you wouldn't be ably to see them because no light reflects from them. So if they are what we think they are, then we shouldn't know of their existance.

But who knows? There might be such a thing as antimatter, and there might not. Black holes might or might not be what they are thought to be. We can only guess, and observe, and laugh at our predictions because we only post cuz we're bored.
