Quantum Immortality is an unproven, hypothesis in the realm of quantum mechanics and consciousness. It stems from the "Quantum Suicide" thought experiment and suggests that consciousness somehow continues indefinitely, even through death, according to the principles of the Many-Worlds Interpretation.

'''Many-Worlds Interpretation'''

Proposes that every quantum event creates a new branch of reality, each with a definite outcome.

'''Quantum Immortality Hypothesis'''

Quantum Immortality postulates that your consciousness somehow "attaches" to the branch where you survive.
You never experience the branch where you die, only the branches where you continue living, regardless of how unlikely your survival might be.
Essentially, you experience repeated "resurrections" across multiple universes, creating the illusion of everlasting existence.
