Time‘s Arrow and the Big Bang

Time marches on. But we’re not exactly sure why. under the quantum laws that govern the subatomic world, time could flow in either direction. The famous second law of thermo- dynamics – i.e. over time, entropy (disorder) increases – argues for a direction of flow, but this doesn’t hold up against our observations of a highly ordered universe. Julian Barbour will discuss these problems and talk about his latest work on gravity and the arrow of time. 

Dr. Julian Barbour is
a British theoretical physicist wand visiting professor at the uni- versity of Oxford, and one of the leading international thinkers
on the topic of quantum gravity. His 1999 book The End of Time advanced the radical notion of timeless physics: Time is an emergent property of the universe.
