Physics informs and challenges our deepest assumptions about time, shaping principles of quantum mechanics and the structure of the cosmos. While some argue time is an essential part of the physical world, others suggest it may not exist at all. In this conversation on Physical Time Professor Tamara Davis and Associate Professor Sam Baron trace the tension between the time we measure and the time we experience, attempting to reconcile both.

Set against Sydney Observatory’s timeless backdrop, On Time is a Powerhouse series exploring the philosophy of time. Across four conversations journalist Rachael Hocking engages with leading thinkers to examine how time governs our world by measuring moments, defining cycles and shaping our deepest sense of self.
