What If You Followed the Atoms in Your Hand Back 13.8 Billion Years?

Every atom in your hand is older than the Earth. Some are as old as the universe itself. Follow four of them — a hydrogen, a carbon, an iron and a gold atom — from the first trillionth of a second after the Big Bang, through dying giants, exploding stars and colliding neutron stars, into the cloud that made the Sun, the young Earth, 4 billion years of oceans and life, a wheat field in Anatolia, a loaf of bread… and your hand. Then: where they go next. Everything in this video really happens. Numbers are real; uncertain science is said as uncertain. One continuous shot. No narration. 4K, 60 fps.
