Quantum Suicide and Immortality

Quantum suicide and immortality is a mind-bending thought experiment stemming from the many-worlds interpretation of quantum mechanics. It suggests that in a universe with infinite parallel realities, a person undergoing a life-or-death quantum experiment (like a gun triggered by a random particle decay) would subjectively always survive. While the observer sees multiple outcomes across branches, their consciousness only follows timelines where they continue existing. This controversial theory implies a form of immortality through quantum branching, though it remains untestable and philosophically debated about whether it truly describes reality or merely illustrates quantum weirdness.
