[00:00:00]You are literally made of dead stars.

[00:00:02]No, seriously, this isn't just a metaphor. Every single atom in your body, the calcium in your bones, the iron in your blood, the oxygen you're breathing right now, was forged inside a massive star billions of years ago.

[00:00:17]When that star ran out of fuel, it exploded in a supernova, scattering those atoms across the galaxy. Over millions of years, they drifted together, formed our solar system, our planet, and eventually, you. Think about that. The iron pumping through your heart right now came from a star that died before our sun even existed. You're not just from Earth, you're from the universe itself.

[00:00:42]Carl Sagan said it best, "We are a way for the cosmos to know itself." If that just blew your mind even a little, like the video, subscribe for more facts that'll make you question everything, and drop a star in the comments if you feel a little more cosmic right now.
