Where Do We Come From? The 13.7 Billion Year Journey of an Atom

Every single atom in your body—the calcium in your bones, the iron in your blood, and the carbon in your DNA—was not made on Earth. It was forged billions of years ago inside the nuclear furnaces of ancient stars and scattered across space through violent supernova explosions. In this cinematic documentary, Brian Cox traces our ultimate creation story back 13.7 billion years to the dawn of time.
