What if time isn’t fundamental at all? Physicist Carlo Rovelli reveals how modern physics, from relativity to quantum gravity, has gradually erased time from its equations. In its place, we find change, entropy, and the deep connection between the universe's evolution and our own perception of its flow. Featuring Rovelli's thermal time hypothesis, this video explores how our sense of past and future arises from the physics of heat.
