Stars in the observable universe — about 10²⁴ (roughly a septillion)

Atoms in your body — about 7 × 10²⁷
That means you alone contain 7,000 times more atoms than all the stars in all the galaxies we could ever see.

And it gets weirder.

Almost every atom inside you — except hydrogen — was once part of a star. The carbon in your cells, the calcium in your bones, the iron in your blood, the oxygen in your lungs — all of it was forged inside stars that exploded long before our Sun was born.

You are a walking collection of stardust. Assembled so precisely that it can think, love, and read this post on @science.
