Secrets of space, the stars, and the origin of everything.
The calcium in your bones, the iron in your blood, the carbon in your DNA — all forged in the hearts of stars that lived and died billions of years ago. 97% of a human's atoms are the same as the galaxy's.
reflection — Every atom in us was born in the heart of a star that died billions of years ago. The star fades, but its light walks in everything alive. We are the universe's memory, walking on two feet.
If the universe were infinite and full of stars, the whole sky would blaze. But it's dark — because the universe has a beginning (13.8 billion years), so light from the most distant stars hasn't reached us, and cosmic expansion shifts their light out of our sight.
reflection — If the universe were eternal and infinite, an unquenchable light would burn us. The darkness of night itself is proof that the universe was born and is expanding. Even the dark speaks, if we listen.
