Quantum Immortality

More about Quantum Immortality

It is well known in the quantum physics community that there are several models for the progression of the wave function. One of these is the Many Worlds or Parallel Universes model, whereby whenever a wave function collapse (branch point, or measurement) occurs, then both outcomes occur in otherwise similar universes, as if an extra thread had been spawned. These parallel universes do not interact with each other, as if their quantum force fields are mutually exclusive. When your body dies in one, your consciousness instantaneously "teleports" to an equivalent instance of you, in another world, as if you had "changed trains mid-journey".
Note that at first you may think that if you die of old age, you would be swapped into another body of the same age, and hence would be no better off than you already were. However, given a potentially infinite domain of parallel universes, you must already exist at all your past ages, so it is far more probable that you would "awaken" in a body much younger than your previous body. This is similar to the doctrine of Reincarnation. For example, if I were to die in the next ten years, it would be nice to awaken into say 1960, then I could "live my life again" maybe making different choices and fewer mistakes :)
