Multiverse

The multiverse is a hypothetical group of multiple universes including the universe in which we live. Together, these universes comprise everything  that exists: the entirety of space, time, matter, energy, the physical laws and the constants that describe them.

The different universes within the multiverse are called "parallel universes", "other universes", or "alternative universes"

 Multiple universes have been hypothesized in cosmology, physics, astronomy, religion, philosophy, 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", "parallel realities", "quantum realities", "alternate realities", "alternate timelines", "alternate dimensions" and "dimensional planes". 

The physics community has debated the various multiverse theories over time. Prominent physicists are divided about whether any other universes exist outside of our own.

Some physicists say the multiverse is not a legitimate topic of scientific inquiry. Concerns have been raised about whether attempts to exempt the multiverse from experimental verification could erode public confidence in science and ultimately damage the study of fundamental physics.Some have argued that the multiverse is a philosophical rather than a scientific hypothesis because it cannot  be falsified. The ability to disprove a theory by means of scientific experiment has always been part of the accepted scientific method. Paul Steinhardt has famously argued that no experiment can rule out a theory if the theory provides for all possible outcomes.

 

Around 2010, scientists such as Stephen M. Feeney analyzed Wilkinson Microwave Anisotropy Probe (WMAP) data and claimed to find evidence suggesting that our universe collided with other (parallel) universes in the distant past
