Into the Impossible With Brian Keating Searching for a Theory of Everything with Max Tegmark, James Beacham & Stephon Alexander (2020)
Oct 23, 2024
Max Tegmark, a physicist at MIT known for his work on multiverse theories, joins experimental particle physicist James Beacham from CERN and theoretical physicist Stephon Alexander to discuss the quest for a unified theory of everything. They dissect the challenges of merging quantum mechanics with general relativity and explore concepts like the multiverse and mathematical beauty. The trio also highlights the role of experimental evidence in shaping theories, debates on consciousness, and innovative perspectives on dark matter, all while engaging the audience with their passion for physics.

Episode notes
Theory of Everything
- A Theory of Everything aims to unify quantum field theory and general relativity.
- These theories describe the universe at smallest and largest scales, respectively, but clash when combined.
Quantum Gravity Approaches
- String theory posits strings as fundamental, generating gravity and supersymmetry from quantum mechanics.
- Loop quantum gravity quantizes general relativity directly, but both approaches have limitations.
Expanding Physics
- Physics has expanded its scope over time, addressing questions previously deemed outside its realm.
- A true Theory of Everything should also explain consciousness and intelligence as information processing.
