multiverse hypothesis

The multiverse hypothesis suggests that our universe is just one of many, potentially infinite universes existing simultaneously. Each universe may have different physical laws, constants, and histories. This idea arises from various theories in physics, including quantum mechanics and cosmic inflation. It offers explanations for some puzzling aspects of our universe, like its fine-tuning for life. While the multiverse is a fascinating concept, it remains speculative; we have no direct evidence of other universes, and it challenges our understanding of reality and what constitutes a universe.
