Erik Curiel explains the challenges in making assessments of probability by making assumptions about the space of universes--or cosmological models--that our theories allow.

Erik Curiel (Munich Center for Mathematical Philosophy) explains the difficulty of making various concepts of and relating to probability precise, rigorous and physically significant when attempting to apply them in reasoning about objects (e.g., spacetimes) living in infinite-dimensional spaces, working through several examples from cosmology. He concludes that most standard forms of argument used in cosmology to estimate the likelihood of the occurrence of various properties or behaviors of spacetimes have serious mathematical, physical and conceptual problems. This lecture was conducted at the Lindeman Lecture Theatre, Clarendon Laboratory, Oxford, on October 6, 2016.

How fragile is our world? What physics led to the existence of life, and how likely --or unlikely-- were these conditions to come about? In this video series we assemble top researchers and approach this question for all angles, with a strong focus on the physics involved. Our talks accessibly discuss how the laws of physics, the initial conditions of the universe, and features of our local world work together to produce the sort of medium-scale world we live in, and assess how likely this...
