This also brings up two more questions about these black holes that the shows on TV do not talk about?So what are the chances of one of these black holes slipping through the cracks so to speak, and ending up much closer to us than we might expect? Please tell me we have this covered, because I know that some employees at NASA have one job and one job only. That is to monitor any object like an asteroid that is headed in our direction.
1) Do these black holes actually move? And if so, what propels them? Is it their own gravity somehow?
2) Is a black hole a perfect and complete sphere? Or is it just a flat circle like they appear on TV. The recent artistic examples of how they appear are interesting. They look like the pupil of an eye with all of that warping imagery moving around it.
