Can we address mysteries of quantum mechanics by supposing that properties of objects long considered to have an independent existence are actually determined solely in relation to other objects or observers? This program is part of the Big Ideas series, supported by the John Templeton Foundation. Participants: Carlo Rovelli Moderator: Brian Greene 00:00 - Introduction 03:06 - Beginning of the Main discussion 03:50 - How does Carlo Rovelli view the Quantum Measurement problem and Many Worlds theory? 12:47 - Relational quantum mechanics 17:27 - Does this approach apply to relativistic quantum mechanics 24:01 - What is needed to fully understand Quantum Mechanics? 28:30 - Summary Part 1 | Can Particles be Quantum Entangled Across Time? - Part 2 | Does Quantum Mechanics Imply Multiple Universes? - WSF Landing Page: - SUBSCRIBE to our YouTube Channel and "ring the bell" for all the latest videos from WSF - VISIT our Website: - LIKE us on Facebook: - FOLLOW us on Twitter: #worldsciencefestival #quantummechanics #briangreene #carlorovelli #physics
