Why does time only move in one direction?
In short: We experience time as a steady flow, but physicists find this perception deeply mysterious. Sean Carroll explores why the 'arrow of time' exists and the fundamental questions that unite classical and modern physics.
While Newton and Einstein represent different eras of physics, they both grapple with the underlying nature of time. Carroll examines the transition from our intuitive perception of linear time to the complex reality of physics, where the directionality of time remains one of the most significant unsolved problems.
The discussion centers on the 'arrow of time'—the reason we experience the past as gone and the future as yet to come. Carroll connects these concepts to foundational questions in quantum mechanics and statistical mechanics, specifically looking at entropy, causation, and the emergence of space and time.
