Again, I’d say you’re misunderstanding the point. The branches aren’t a real thing in quantum mechanics. They’re just a particular way of looking at the wave function of the universe. In the evolution of the wave function, it sometimes will ‘split’ into two parts that are essentially independent of each other and may have different amplitudes associated with them. These amplitudes may be shown to correspond to the (square root of the) probability of finding yourself in one branch or another. However, if you knew about the entire wavefunction as an outside godly observer to the universe might, then there’d be no point in speaking of ‘branches’.
