Three Ways Physicists Think Reality Works – Quantum Reality with Jim Al-Khalili

Описание: What if the universe really is made of parallel worlds? What if particles are riding the trajectory of a hidden wave? What if quantum wavefunctions collapse spontaneously due to real physical processes? In episode two of our series on quantum realism, Jim Al-Khalili talks to three experts who each champion different interpretations of quantum mechanics – the Many Worlds Interpretation, Pilot Wave Theory and Objective Collapse.

They are three fascinating ideas and this is one of the deepest debates in modern physics. Each one attempts to rescue reality by offering an alternative to the traditional Copenhagen interpretation of quantum mechanics, and giving explanations to the measurement problem. We touch on determinism, Schrödinger's Cat, the double-slit experiment and when quantum probability becomes reality.

Which theory do you find most compelling?
