what is quantum immortality?
it's the logical conclusion from quantum physics
and not just from the many worlds theory

even without many worlds, quantum immortality is real
>how?
the delayed choice quantum eraser experiment
>what's that?
it's proof that if a measurement is destroyed,
then the previously collapsed (real/actual) fact is rewritten
such that it's as if it's always been in a state of superposition
>what does this have to do with quantum immortality?
if you ever die, your measurement is destroyed
and your mortal life is rewritten as if it's always been in superposition
ie, not in any collapsed or "real" or "actual" state.

you don't need to invoke many worlds theory
for quantum immortality to be true
