The Physics and Philosophy of Time
Centre de Physique Théorique, Aix-Marseille University
Explains why a single universal 'now' vanishes in general relativity and loop quantum gravity, and how thermal coarse-graining gives rise to macroscopic time.
From Boltzmann to quantum theory, from Einstein to loop quantum gravity, our understanding of time has been undergoing radical transformations. Carlo Rovelli brings together physics, philosophy and art to unravel the mystery of time.
