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 indefinitely. 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 always experience the life of a “you” that survives, no matter how unlikely such a continuity becomes.
