Time asymmetric extensions of general relativity

Lee Smolin (Perimeter Institute) // February 8, 2016


Abstract: I describe two ways to extend general relativity to a time asymmetric theory and discuss some possible observational consequences of them. These are motivated by Penrose’s hypothesis that the specialness of the cosmological initial conditions needed to explain the arrows of time can in turn be explained as a consequence of a time asymmetric fundamental theory governing the very early universe.
