When we 'look' at blackholes, we see matter being sucked into it and compressed to an infinitely dense point, a singularity. Our universe was a singularity with temperature and density (maybe infinitely small volume is the correct phrase) going to infinity. Why is the theory that our universe itself came from a blackhole in another universe so easily dismissed? Or that our universe is eternal and soon enough a blackhole will get so large it will create another big bang, spitting out all the matter it swallowed. I'm not sure if I'm getting this right but blackholes eventually disperse, but the matter that it swallowed up is nowhere to be seen. Is it stupid to suggest that maybe our universe was created when the matter from another universe was sucked into it? If not can you please explain why this theory either doesn't work or is proven to be false? Thanks.
