Could 'Star Trek: Discovery' Be Right About Parallel Universes? Vaulting Ambition

The idea of parallel Universes has been around for over 60 years now, giving a theoretically physical existence to all the possible outcomes of our reality, including the ones that didn't occur. In our current reality, once a quantum decision is made, or an observation constrains the possible remaining outcomes, these other Universes must split off irrevocably from the one we inhabit. In Star Trek: Discovery, however, there remains a connection between the Universe where the original crew is from, and the mirror Universe, which split off from the original timeline some 200 years ago. As we learn more about the two different Universes, we find commonalities: people, relationships, even wars and betrayals. After an incredible plot twist, we finally discover why, but the question of how to make this possible lingers.
