Why we are made of stardust?

When stars get to the end of their lives, they swell up and fall together again, throwing off their outer layers. If a star is heavy enough, it will explode in a supernova. So most of the material that we’re made of comes out of dying stars, or stars that died in explosions. And those stellar explosions continue.

What does we are made of stardust mean?

The outer layers collapse onto the core at nearly half the speed of light. The star then explodes outward as a supernova. This supernova explosion creates all the elements heavier than iron. And, these particles were all forged in the nuclear fusion fires of stars. We truly are made of star dust.

What is the human made of?

The human body is approximately 99% comprised of just six elements: Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. Another five elements make up about 0.85% of the remaining mass: sulfur, potassium, sodium, chlorine, and magnesium. All of these 11 elements are essential elements.
