The Multiverse is very huge. Our local Multiverse has 10^10^118 universes, although a multiverse can contain anywhere from only 2 universes to omega universes. Our universe lasts long, most of them only live for xonoseconds and pop. The diameter of our Multiverse is on the order of 10^10^118 light years across! A multiverse is a self-contained group or larger bubble filled with a finite or infinite number of universes. In many cases, the term is used to define, a larger bubble filled with a finite or infinite number of universes. In many cases, the term is used to define the hypothetical set of every single possible universe, including the universe in which we live.

## Formation

A googolplex years ago, there was a huge crash against two multiverses, forming our Multiverse, and each fragment is a Fragmentverse.

## Types of Multiverses

### Extention Multiverse

It is an infinte universe collection. The universes in this type of multiverse should be refreshing itself and should have a starting and extention. It results with infinite amount universe that all has the same physical laws but different starting and extention. So matter configurations are also different. Universal distance should be 10^10^115 lightyears.

### Physical Multiverse

Universes should be multi-dimensional (at least 1D) and should be refreshing itself and streching forever. These type of multiverses may contain Mini-Multiverse. Physical laws of universes should be different.

### Quantum Multiverse

In a quantum multiverse, each possible state of the universe is a different basis vector in a Hilbert space, and the overall state of the universe is a vector in this Hilbert space; this state is called the universal wavefunction. =

Systems that are separated out from their environment can be factored out of this vector, and when they interact with the environment ("are measured"), each possible state of the system leads to a different world.

For example, suppose there is an isolated two-state system with equally likely states $|\psi_1\rangle$ and $|\psi_2\rangle$, and the rest of the universe with the state $|\Psi\rangle$ such that the universal wavefunction can approximately be written as $(|\psi_1\rangle + |\psi_2\rangle)|\Psi\rangle$; if this system interacts with the rest of the world, then it may no longer be possible to factor out, and the universal wavefunction becomes $|\psi_1\rangle|\Psi_1\rangle + |\psi_2|\Psi_2\rangle$, now containing two different worlds.

### Mathematical Multiverse

In a mathematical multiverse, all mathematical structures are real, and each mathematical structure corresponds to a different universe.

?!!?!!?!!?

## User Multiverse Types

These are custom multiverse types made by users that are a bit different than the main types of multiverses.

### VoidSansXD's Proposal

VoidSansXD proposes that all types of Parallel Universes with the same universal properties (AKA laws) are all put into one set of parallel universes, and other sets of parallel universes contain Universes with different universal properties/laws. For example, all universes where the 4 fundamental forces and all subsets of it are the same as ours would be 1 set, and another set could have a different size for the Planck Length. They could also have different probabilities for things to happen, meaning that quantum physics/entanglement being different in different universes/objects could also put universes into different sets. Basically, this proposal is a mix of the mathematical multiverse and the extention multiverse.
