Does Quantum Immortality Save Schrödinger's Cat?
Summary
PBS Space Time explores the quantum measurement problem, arguing that decoherence alone doesn't explain why we observe a single reality. The host introduces the "quantum immortality" thought experiment to test the Many Worlds interpretation against Copenhagen. The episode also answers a doomsday argument challenge regarding humanity's survival odds and addresses listener questions on observer consistency and quantum erasers.
