Many-worlds interpretation

The Many-Worlds Interpretation (MWI) of quantum mechanics suggests that every possible outcome of a quantum event actually occurs, but in separate, parallel universes. Instead of collapsing into a single state when observed, particles can exist in multiple states simultaneously. Thus, when a decision is made or an event occurs, the universe splits into different branches, each representing a different outcome. This means there are countless versions of reality coexisting, each with its own unique history based on different choices or events, expanding our understanding of the universe beyond a single, linear timeline.
