Free · In‑App Purchases
The iron in your blood came from a dead star. Trace 13.8 billion years to you.
The iron in your blood came from a star that exploded long, long ago.
BIG BANG TO US is an interactive science app that lets you trace the history of the universe with your fingertips, from the Big Bang 13.8 billion years ago to the moment stars were born, died, and forged the very elements that make up your body.
And at the end of that journey, you find... us.
"A natural journey that begins with the Big Bang and leads to the story of how we are descendants of the stars. A wonderful piece of interactive science content that students and adults alike can deeply connect with and enjoy."
Sunkyung Park (Astronomer, science communicator Ujutoon @uju_toon)
