The many-worlds interpretation is a particle physics idea that attempts to explain what’s really happening when something is in superposition. It’s more of a guide on how to interpret particle-wave duality. It doesn’t really have much meaning at the macroscopic level, that is not the purpose.

The Short Answer

The many-worlds interpretation is a particle physics idea that attempts to explain what’s really happening when something is in superposition. It’s more of a guide on how to interpret particle-wave duality. It doesn’t really have much meaning at the macroscopic level, that is not the purpose. Edit: multiverses are a completely separate idea relating to how we explain why our universe’s constants have the value they do
