So a friend of mine and me were speculating about black holes. He theorized that black holes led to a 4th dimension. From that i started to question what black holes really are and how they "work". So heres my question:
From what i have learned my whole life, black holes form from stars or other masses that have so much mass and gravity at 1 point that they cave in on themselves and create a hole that will suck in everything around it which will never be seen again including light. Could it be similar to taking a piece of paper, laying it out straight in mid air, and pushing a pencil in the top until the paper bends down further and further and eventually rips making a hole? Perhaps the universe is a "plane" and nothing can escape because anything that travels over it falls through, meaning that light traveling across would also drop down? perhaps dimensions are laying ontop of eachother and this amount of bend in space connects the 2 dimensions through the hole that is created, which would mean in the 4th dimensions universe the opposite of a black hole is happening where instead of everything being pulled in, its being pushed away explaining why light goes in but dosnt come out.?
Thats just a few speculations i had and was wondering if any of them were moderately right/possible or maybe someone could tell me how it really works, i would appreciate it.
