Subquantum physics: nonlocality, pilot-waves & breaking the Born rule with Prof Antony Valentini

Quantum theory appears to allow some kind of connection between entangled particles, but not enough to send messages. Antony Valentini argues this is a conspiracy: there must be something deeper than quantum, where nonlocality can actually be used to send messages, but it is hidden from view in standard quantum experiments. In this episode of the Quantum Foundations Podcast, Valentini uses Pilot-wave theory to explain the physics of the nonlocal subquantum world. He discusses various ways that the theory could be experimentally tested, by looking for signatures of violations of the Born rule in extreme environments, such as the early universe. He also discusses the radical technological implications of subquantum physics, if we were able to harness it.   Valentini recently released a book for a general audience explaining these ideas, "Beyond the Quantum: A Quest for the Origin and Hidden Meaning of Quantum Mechanics".
