Do You Know What Time It Is

Do You Know What Time It Is

Particle physicist Professor Brian Cox asks, ‘What time is it?’ It’s a simple question and it sounds like it has a simple answer. But do we really know what it is that we’re asking? Brian visits the ancient Mayan pyramids in Mexico where the Maya built temples to time. He finds out that a day is never 24 hours and meets Earth’s very own Director of Time.

He journeys to the beginning of time, and goes beyond within the realms of string theory, and explores the very limit of time. He discovers that we not only travel through time at the speed of light, but the experience we feel as the passing of time could be an illusion.
