comment Is it possible to have a black hole in empty space?
Isn't that what I'm doing though? Where does the continuum end and the matter of fact begin in this theory? Take, for instance, a black hole that had a large gap between two ends of its mass, and that gap was held apart by metal bars (unobtainium bars :). Would that no longer be a black hole, even though its center of mass was between the two?

What makes a black hole gain physical properties? It's not just one thing, but rather a concept derived from the center of mass of its constituent particles, no?

Isn't a center of mass meaningful? After all, isn't that what a black hole is comprised of, non-contiguous particles with a center of mass?

Mass so great that light cannot escape.

@RobJeffries the actual star. In other words, Earth would be slamming into the star in this scenario.

@HDE226868 If it doesn't matter who does an experiment, why don't I personally do an experiment in my kitchen sink to prove whether or not motor oil is made of oxygen and gold. I'll publish my results just for you.

Thanks so much for all the info, Floris!
