take this for your trouble friend

So I was talking to a friend and an idea came up that was absolutely fascinating to me. It was the idea of a cyclic closed universe that seemed like an open universe. It was described by putting a 2d universe on a 3d sphere. The "suppose that" was that the amount of matter existant on the outmost surface of the sphere was directly correlated to the density of matter necessary to form a black hole. As the universe continued to expand, black holes would eventually come into existence and matter would begin to fall in towards the center of the sphere. Eventually matter would become more and more sparse and less and less existent on the outmost surface of the sphere that it would come down to the last particle which according to the "suppose that" would satisfy the density requirements and form its own black hole, beginning it's fall inward to the center of the universe. At this point no more matter would exist and as such the requirement for forming a black hole would be zero, causing the universe to collapse, driving all the matter falling into the universe to a single point like a massively powered atom smasher causing the matter to annihilate into energy and restart the universe. I'm curious if such an idea could be a viable theory about the universe or not.

Good day to you, sci. I just have one question before I get going with my math homework. I've been trying to figure it out myself for a while and I have a few theories, but fuck that.


What happens when a black hole "collides" with another black hole?
