YouTube Description
as posted by the channelIn this episode, Neil deGrasse Tyson and Chuck Nice speak with physicist Sean Carroll about whether entropy actually creates time. Sean explains that entropy does not generate time itself, but it gives time an arrow—a direction from past to future. Even if the universe were to stop expanding and begin collapsing, entropy would still increase. The key distinction is between time (which can exist without direction) and the arrow of time, which entropy provides through statistical mechanics and phase space dynamics.
