Many-Worlds Quantum Theory

The Many-Worlds Quantum Theory suggests that every time a quantum event occurs—like a particle changing state—all possible outcomes happen, but in separate, branching universes. Instead of one outcome happening and the others being "discarded," all possibilities are realized simultaneously in different realities. This means our universe is just one of countless others, each with its own version of events. The theory aims to solve traditional quantum puzzles by removing the need for wavefunction collapse, implying that all outcomes are valid and coexist in a vast multiverse.
