Multiverse

"There are hundreds and thousands of multiverses dear, not just a single one. Just like how there's countless continuities, within each of these continuities are countless multiverses, and within each multiverse are countless universe of its own,"

- Raziel.

A Multiverse is an overall massive collection of universes and timelines.

Overview
A multiverse consists of a very large number of universes, millions of which have been cataloged as universal streams. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, and the physical laws and constants that describe them. Between these streams, outside of time and space, exists the inter-dimensional void of transwarp. On a cosmic scale, travel between universes is comparatively rare, but there exist certain groups and individuals dedicated to monitoring, moving between, and/or protecting the many worlds of a multiverse.

The structure of a multiverse, the nature of each universe within it, and the relationships among these universes differ from one multiverse hypothesis to another. Multiple universes have been hypothesized in cosmology, physics, astronomy, religion, philosophy, transpersonal psychology, and literature, particularly in science fiction and fantasy. In these contexts, parallel universes are also called "alternate universes", "quantum universes", "interpenetrating dimensions", "parallel dimensions", "parallel worlds", "alternate realities", "alternate timelines", and "dimensional planes".

Description
A multiverse is based on the supposition that what we have to this point considered to be “the universe” is but a small component of a vast, possibly infinite, assemblage of universes. A multiverse principle is an attempt to evade evidence for the apparent fine-tuning of cosmic laws, values and constants such that the universe would be conducive to bio-habitability. The core thesis of a multiverse concept attempts to expand one’s probabilistic resources beyond that which is available in the observable universe such that the likelihood of attaining a single bio-habitable universe by chance is rendered more plausible.

There are several fundamental problems with this proposition, the key problem being that it is both unnecessary and ad hoc. There is no good scientific reason to think that we reside in one universe within a multitude of parallel universes. There is also no reason to think that there should be a mechanism for generating such universes, each with its own fundamental constants and values.

The proposition thus only succeeds in throwing the paradox back one step, as one could then easily ask who built the generator to give rise to this cosmic lottery. A second difficulty with this hypothesis is that a universe which is in a state of continuous expansion cannot be eternal. It stands to reason, therefore, that it is possible only a finite number of universes could have been generated, and there is no guarantee that a finely tuned bio-habitable universe would have emerged. However, a multiverse is quite small compared to the Omniverse.

Religious Texts
The concept of multiverses appear many times in Hindu texts:
 * "Because You are unlimited, neither the lords of heaven nor even You Yourself can ever reach the end of Your glories. The countless universes, each enveloped in its shell, are compelled by the wheel of time to wander within You, like particles of dust blowing about in the sky. The śrutis, following their method of eliminating everything separate from the Supreme, become successful by revealing You as their final conclusion." - Bhagavata Purana 10.87.41.


 * "Of those countless universes, O Rama, in some there are only plants; some have Brahma, Vishnu, Rudra and others as the presiding deities, and some have none at all; in some there are only animals and birds; in some there is only an ocean; some are solid rocks; some are inhabited only by worms; some are pervaded by dense darkness; in some gods dwell; some are forever illumined. Some seem to be heading towards dissolution; some seem to be falling in space towards destruction." - Section III. Utpatti Prakaranam - chapter 29-30.

Infinite other universes are mentioned in Buddhist texts such as the Apannaka Jataka:
 * "'Disciples,' the Buddha said 'nowhere between the lowest of hells below and the highest heaven above, nowhere in all the infinite worlds that stretch right and left, is there the equal, much less the superior, of a Buddha. Incalculable is the excellence which springs from obeying the Precepts and from other virtuous conduct.'" - Apannaka Jataka.

Baha'i Faith holy texts and scriptures teach about infinite universes created by God.
 * "Know thou of a truth that the worlds of God are countless in their number, and infinite in their range. None can reckon or comprehend them except God, the All-Knowing, the All-Wise." - Suriy-i-Vafa.


 * "There are infinite Manifestations of God in the infinite worlds of God." - ALawh-i-Aflákiyyih: Tablet of the Universe.

Quotes

 * "To one such as I the Multiverse is akin to those of paintings lined up within a museum that stretches infinitely. But for a mortal such as you...it is a concept of which you know frighteningly little." - Remph.


 * "Good and evil exist as two sides of the same coin. It is through them that I give logic to all things. There are infinite possibilities in the world, each possibility is a different version of each story written by me of each event that occurred in the universe. For example, in this universe, you are suffering, however, in another, you are living a life full of glory and happiness." - God talking about a Multiverse.
 * "Are you telling me that in one world I am suffering from aches and boils, while in another I am blessed and glorified?" - Job's reply.
 * "Exactly, Job." - God.
 * "That doesn't make any sense." - Job.

Trivia

 * Some beings, like God, Arbeshk, Yog-Sothoth, and others are known to exist beyond a multiverse, the Arcuthas could also technically exist outside a multiverse, as God created the realm they live in before the Big Bang, but this is uncertain.
