Where did we come from? Where will we go?

Professor Brian Cox tries to answer the questions - what are we? And where do we come from? In this video, he reveals how our origins are entwined with the life cycle of the stars. But he begins his journey here on Earth, in Nepal where he observes a Hindu cremation. Hindu philosophy is based on an eternal cycle of creation and destruction, where the physical elements of the body are recycled on to the next stage. Brian draws a parallel with the life cycle of the stars that led to our own creation.
