The Many-Worlds Interpretation of quantum mechanics holds that every time a quantum experiment with different possible outcomes is performed, all outcomes are obtained, each in a different newly created world, even if we are only aware of the world with the outcome we have seen. It declares that there are many worlds which exist in parallel at the same space and time as our own.[1]

There are multiple versions of you.[1]

Your actions can split the universe since you are made up of quantum particles.[1] [2]
