That was definitely written by computer. Disjointed, repetitive, and switches topics.

There is nothing special about the gravitational pull of a black hole. It has pull according to its mass, just like every other object. If you have a black hole that is the mass of the earth, then about 4000 miles away from it, you'll feel a 1G pull.

If the sun was suddenly replaced by a black hole, we'd continue to orbit. We just wouldn't get any sunlight, and of course that would be an extinction event, but that's beside the point

This is like that episode of The Office, waiting for the screensaver on the DVD player to hit the corner.
