Some scientists apparently un-ironically speculate that we may live *inside* a black hole. Well, that would explain a thing or two, I suppose...
Note what Sabine is saying here: there are several competing theories about black holes, each mathematically "correct". Yet, only one of them can be true - or none of them are. So naaah, you can´t just "shut up and do the math", as some midwits are trying to tell us.
Shut up *and do the empirical research* is the bottom line here. Note also that many scientists themselves suspect that the simplest explanation (a black hole is a singularity) simply can´t be true...and so the speculations continue.
I actually see that as a singularly good thing!
