Give me a short bulleted list of the key points about the parallel universes in this passage.

Context: The multiverse is a hypothetical group of multiple universes. Together, these universes are presumed to comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called "parallel universes", "other universes", "alternate universes", or "many worlds". One common assumption is that the multiverse is a "patchwork quilt of separate universes all bound by the same laws of physics." The concept of multiple universes, or a multiverse, has been discussed throughout history, with origins in ancient Greek philosophy. It has evolved over time and has been debated in various fields, including cosmology, physics, and philosophy. Some physicists argue that the multiverse is a philosophical notion rather than a scientific hypothesis, as it cannot be empirically falsified. In recent years, there have been proponents and skeptics of multiverse theories within the physics community. Although some scientists have analyzed data in search of evidence for other universes, no statistically significant evidence has been found. Critics argue that the multiverse concept lacks testability and falsifiability, which are essential for scientific inquiry, and that it raises unresolved metaphysical issues.

Answer: Here are a short bulleted list of the key points about the "parallel universes" (the "multiverse", "other universes", "alternate universes", or "many worlds"):

- It is a hypothetical group of multiple universes which together are presumed to comprise  the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them.

- It has been the subject of debates in cosmology, physics, and philosophy.

- Some argue that the "parallel universes" concept lacks testability and falsifiability, and so it is a more of a philosophical notion rather than a scientific hypothesis.
