multi-universe theory

The multiverse theory suggests that our universe is just one of many, each with its own distinct laws of physics, constants, and properties. These multiple universes, or "parallel worlds," could exist in a vast cosmic landscape, possibly arising from variations in the Big Bang or quantum processes. While our universe appears unique, the multiverse hypothesis implies that countless other universes may exist beyond our observational reach. This idea helps explain some scientific questions about fine-tuning and cosmic origins, though it remains a theoretical framework without direct empirical evidence.
