Multiverse

The Multiverse is a collective of an infinite ($$\aleph_0$$) amount of Universes all in one place. This is possible because there are 4 spacial dimensions while Universes are only three Dimensional. There are also an infinite number of Multiverses which have varying laws of physics giving each Multiverse its own unique tone, but since there are infinite Multiverses there will be an infinite number of copies of a Multiverse.

Universe Creation
Since each Universe is created differently varying things can happen to the shape, matter to anti-matter and dark matter amount in each Universe.

Multiverse Creation
Multiverse creation spontaneously happens when an infinite amount of Universes start at the same time, then the Universes are all transported into the Multiverse (before they are in nothing) and start drifting around. As the Multiverse is contained by the Hyperverse there are also an infinite amount of Multiverses inside the Hyperverse. This is how there can be an infinite amount of Universes being created at once.
