Iamon_lyme: Singularities (as the scientists say are not bound by large scale physics but quantum level physics.
......Art's point of.... "which I can't explain but then neither can physics." ... is false.

Einstein's physics do not work at the quantum level, but he was ok with that and so are the scientists today. If quantum level physics does not work they.. we couldn't be here. Electrons move by quantum rules.. Plants in their daily photosynthesis use quantum level physics to be ultra efficient in the absorption and utilisation of sunlight.

As to things being infinite..... I'm not sure it is... relatively.

"but I don't think it's because of some crack leaking gravity from another dimension into ours."

It's not a crack.. a fold, a bend, a rotation.. but not a crack... and it's still in one of our dimensions just one of the many our eyes were not designed to see.

"Scientists should stop screwing around with fancy and imaginative theories, and go back to finding simple and common sense anwsers."

.... why? It is our curiosity at the majesty of the universe that lets us understand how wonderful it is. We still are learning about our Universe, seeing as less then a hundred years ago we did not know there was one... just a galaxy as far as Earth knew!!
