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 world was to come about.
