Quantum immortality is the assertion that the Many-worlds interpretation of quantum mechanics and pattern identity theory imply immortality or, more aptly, that one should expect one’s subjective experience to persist indefinably. The basics of the argument is as follows: No matter how likely you are to die in a given situation, there is always a greater-than-zero percentage of worlds in which you survive. As one can’t experience nonexistence, you will only ever experience the life of a “you” that continues, no matter how unlikely such a continuity is objectively.
