Actually… not necessarily true. If the quantum multiverse is real there may be a version of you that lives forever.Hosted by Matt O'DowdWritten by Matt O'DowdGraphics by Leonardo Scholzer, Yago Ballarini, and Pedro OsinskiDirected by: Andrew KornhaberExecutive Producers: Eric Brown and Andrew KornhaberEnd Credits Music by J.R.S. Schattenberg: https://www.youtube.com/channel/UCRl6-nb4iOnsij-vnpAjp0QIf we can’t ever peer into these other realities that are used to explain quantum mechanics, how do we know they exist? In order to understand what happens to those different branches, and to understand why we find ourselves in one of them, we need to embrace one of the interpretations of quantum mechanics. For example the Copenhagen interpretation, which says that the wavefunction branches that we don’t observe somehow vanish at the moment of measurement. Or the Many Worlds interpretation, which states that those other branches are just as valid as ours - implying that reality may split and multiply in all possible ways. In that case we only see one branch because we live in that branch, and the others are rendered inaccessible by decoherence. But today I’m going to offer a test. Admittedly NOT a very useful one - but one that’s fun to think about. We’ll call this test quantum immortality. It’s based on the famous Schrodinger’s cat thought experiment.
