Everett's Many-Worlds Theory

Everett's Many-Worlds Theory posits that all possible outcomes of a quantum event actually occur, but in separate, branching worlds. When a quantum system changes state, the universe splits into multiple versions, each reflecting a different result. Instead of collapsing into a single outcome, these multiple worlds coexist simultaneously, evolving independently. This idea removes the need for mysterious wavefunction collapse, suggesting that our universe is just one branch among countless others, each representing different possibilities, all existing in a vast, interconnected multiverse.
