text: what really is the universe? can it be just part of something even bigger? stephen hawking said the universe is shaped like a pear with the singularity or big bang at the bottom and the curves in space time. however their is also the fecund universe theory. this states that when one universe has a black hole, time does not end inside a black hole but initiates a quantum bounce. this creates a singularity on the other side creating a baby universe. each new universe the laws of physics are the same but their may be slight variations. the beliefe of our universe being the way it is, is because ours is how universes typicaly develope. this is basicaly the anthropic principle, which states, if our universe was not the way it was we would not be here. richard feynman states that a particle will take every single path through space time available. meaning each universe could be another possible outcome of reality. a final note on one of the particles that exist in the universe (or perhaps multiverses) is the electron. all electrons are the same one curve. also electrons move backwards in time while positrons move forward. so the electron is a curve on a atomic scale that moves backwards in time. this is all highly theoretical. however i hope my answer was helpful.
