In quantum mechanics, besides the Copenhagen interpretation where the wave function collapses upon observation to yield a single measurement value, there is the many-worlds interpretation initiated by Everett. If this many-worlds interpretation is correct, it implies that the real world splits into many, leading to the existence of so-called branching universes (parallel universes). Traditionally, it has been considered impossible to prove this existence, but I have discovered that it can logically be demonstrated by conducting experiments like the ones outlined below. Therefore, in order to deepen our understanding of the universe, I would like to have individuals with the necessary technology and knowledge carry out this experiment to prove the existence of branching universes.
