multiverse

The multiverse is a concept suggesting that our universe is just one of many, possibly infinite, universes that exist simultaneously. Each universe might have different laws of physics, dimensions, or histories. This idea arises from various theories in cosmology, quantum mechanics, and string theory, suggesting that our universe is part of a larger "multiverse" system. While the multiverse is still a speculative idea without direct evidence, it raises fascinating questions about the nature of reality and existence beyond what we can observe.
