I'm not sure if this has been theorized before by anyone but this is what I came up with as a theory as to how universes are formed and how "big bangs" occurr. I'm only in high school and haven't taken physics but I don't see how this can be ruled out all together. Basically this is about black holes and rips in the fabric of a universe. Here's a few (poorly drawn) images to explain this visually a bit: So in simple terms, when a black hole gets powerful enough, it rips a hole in the fabric of the universe and thus creates a new universe for it to throw all of the matter it's collected. What brings me to believe this may be a good theory is that I've heard from physicists that no theory man has thought up can explain how the big bang happened and my theory simply says all that happened when the universe was created is a bunch of matter from a much larger universe was sucked into ours by a black hole's gravity and the rip in the universe. One thing this DOESN'T explain is how the first particle of matter... the first electron or atom or whatever... was created and I don't intend it to. All this really explains is possibly how the big bang occurred and other universes. I'm also not exactly sure how a universe would "heal" it's rip or if it even would (this could mean multi-universal travel I suppose). So is my theory completely stupid or is there a possibility in there some where?
