I’m sticking this under philosophy because I don’t trust my background in physics enough to thing this is completely accurate, but I thought of something today while watching a documentary on Steven Hawking, and thought I should write it down.
Black holes are singularities — essentially the atomic roach motel (matter checks in, but it doesn’t check out). The big bang that started the whole shebang was also a singularity. I know gravity messes with the localized passage of time, so is it possible that our entire universe is merely the inside of a black hole? In which case, where do our black holes go?
If anybody has any input in this, feel free to leave a comment, even if it’s just on the philosophical nature of the topic and not the physics side.
