  As black holes don’t let any light escape, there is no way for us to see what’s inside them.

  A black floor?

  I’m pretty sure no-one knows but I know that one has recently been imaged. Please correct me if I’m wrong but I was under the impression that a black hole is a region of space which is unimaginably dense? If that is the case, does that necessarily constitute a “hole”? If not a hole then there would be no “bottom”? Complex stuff, I’ll stick to forensics! 😉
