The Arrow of Time feat. Sean Carroll

The video explores the concept of time, highlighting the differences between the past and future. It explains that while time seems directional, the fundamental laws of physics do not distinguish between past and future. The increase in entropy, or disorder, is a key factor in this perceived directionality, as described by the Second Law of Thermodynamics. The video also delves into cosmology, questioning why the universe began in a highly ordered, low-entropy state, and how understanding this can clarify the arrow of time.
