Synopsis

US Customers Only. Do we really know what time it is? CERN physicist Professor Brian Cox (and author of E=mc2) unlocks the secrets of time in this entertaining and informative program. His journey starts with the Sun, our historical dictator of time, but Brian discovers that the world doesn’t always spin like clockwork – in fact, it flutters, like an irregular heartbeat. In his search for a more reliable way to tell the time, he experiences the physical definition of a second with a cesium atomic clock, then jets across the Atlantic to discover that time can speed up or slow down depending on how near an object is to a strong gravitational field. Still looking for answers, he consults modern ideas like string theory and quantum mechanics that are pointing the way to future breakthroughs. Time dictates what we do, when and for how long. In What Time Is It?, Brian Cox deepens our understanding of time while stirring the depths of our imagination.
