    Brian Keating: Cosmology, Astrophysics, Aliens & Losing the Nobel Prize | Lex Fridman Podcast #257

    Brian Keating, Lex Fridman

    Experimental radio astronomer Brian Keating discusses how telescopes serve as time machines that fundamentally altered human civilization, while detailing his critical examination of cosmological models like Conformal Cyclic Cosmology and the multiverse. He reflects on the 2014 BICEP2 controversy, the subsequent retraction of claimed primordial gravitational wave detections due to interstellar dust, and critiques the competitive nature of the Nobel Prize system. Keating concludes by outlining his "Assayer Project" to rigorously evaluate competing theories of everything through Bayesian reasoning and shares his pessimistic outlook on the likelihood of finding technological extraterrestrial life.
