The Emergent Multiverse - Quantum Mechanics & The Many Worlds Interpretation
The Many Worlds Interpretation (MWI) of quantum mechanics holds that quantum theory - our best current theory of physics - is correctly understood as claiming that there are many worlds that exist in parallel to our own and which branch constantly off our own. The existence of the other worlds makes it possible to make sense of physics without action-at-a-distance, objective randomness, or any strange role for "observer" or "consciousness". These lectures discuss this interpretation of quantum mechanics and what would follow from its being the correct one.
This series is from Oxford University.
The Emergent Multiverse: The Plurality of Worlds - Quantum Mechanics 53:30 David Wallace examines the justification for interpreting the superposition states as multiplicities. This is the first talk on the Many Worlds Interpretation (MWI) of quantum mechanics. The MWI holds that quantum theory - our best current theory of physics - is correctly understood as claiming that there are many worlds that exist in parallel to our own and which branch constantly off our own. The existence of the other worlds makes it possible to make sense of physics without action-at-a-distance, objective randomness, or any strange role for "observer" or "consciousness". These lectures discuss this interpretation of quantum mechanics and what would follow from its being the correct one.
