What is time? From atmospheric phenomena to the mechanisms of the human body, this documentary with breathtaking images explores the most recent scientific theories.


1. Journey to the sources of time

Hurricanes, like the one pictured here sweeping across Florida, are the result of a long-lasting chain of causes. The circulation of cold ocean currents contributes, over months and years, to their formation. But these currents themselves depend on what is called in English the great ocean conveyor, or "ocean conveyor belt", which obeys a cycle of a thousand years. The chemical composition of the seas changes very slowly, with successive ice ages. To solve these puzzles, scientists must try to trace the origins of the universe, spanning some 13 billion years.
