What is multiverse? How many multiverse are there ? Is god exists in multiverse

The concept of a "multiverse" refers to the idea that there may be multiple universes in addition to our own. The idea of a multiverse comes from several different branches of physics, including cosmology and quantum mechanics.

In cosmology, the concept of a multiverse is suggested by the theory of cosmic inflation, which proposes that the observable universe is just a small part of a much larger, inflating region that gives rise to an infinite number of pocket universes.

In quantum mechanics, the concept of a multiverse is suggested by the many-worlds interpretation, which proposes that every time a quantum system can take multiple paths, the universe splits into multiple "worlds," each corresponding to a different path.

It's not a scientific hypothesis but rather a concept of interpretation rather than a scientific hypothesis that has been proven, so it is uncertain how many multiverse are there or their nature.

As far as God is concerned, the concept of multiverse is a physical hypothesis, and the question of whether or not a god or gods exist is a matter of religious or philosophical belief rather than one that can be answered by science. Therefore, the question of whether or not a god or gods exist in a multiverse is a matter of personal belief rather than one that can be answered by science.
