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. From the breaking of primordial symmetries in the first seconds of the Big Bang to the cosmic cycle of stellar death and rebirth, we explore how physics and cosmology reveal a profound truth: our story is the story of the universe. Discover the jaw-dropping cosmic connection between the limestone peaks of the Himalayas, the gold in a wedding ring, and the very fabric of human life.
