Superposition, Entanglement, and the Many-Worlds Interpretation

From StarTalk.

Neil deGrasse Tyson, joined by astrophysicist Charles Liu, along with Chuck Nice and Gary O’Reilly, dive into the fundamentals of quantum mechanics—superposition, wave–particle duality, entanglement, qubits, and the collapse of the wavefunction—using pop-culture references like Doctor Manhattan from Watchmen to make these abstract ideas more accessible. The discussion builds toward a critical examination of the Many-Worlds Interpretation, debating whether it offers a genuine explanation of quantum uncertainty or simply sidesteps unresolved questions about how and why wavefunctions collapse.
