In the traditional view of fundamental physics time is an illusion: it emerges as we coarse grain, it’s not a fundamental quantity of nature. The evident time-asymmetry of nature is held to be an accident, due to improbable choice of initial conditions. In collaboration with Lee Smolin we proposed the diametrically opposed view: the hypothesis that, in the quantum gravitational regime, time is both fundamental and irreversible, as opposed to reversible and emergent. We describe a new class of models of quantum space-time in which space-time itself, as well as aspects of quantum theory, emerge under natural conditions. The framework is based on arXiv:1307.6167 and subsequent papers.
