Massive stars forge elements through nuclear fusion over millions of years, creating hydrogen, helium, carbon, oxygen, and eventually iron; when an iron core forms, fusion stops, gravity causes rapid core collapse, and the resulting supernova explosion scatters these elements throughout the universe, meaning the oxygen we breathe and calcium in our bones were created inside dying stars.

Your Bones Were Forged Inside a Dying Star追加:
The universe is tearing itself apart right now.
And you are made of the wreckage.
Here is the truth most people never hear.
A massive star does [music] not simply die.
It spends millions of years forging [music] elements inside itself.
Layer by layer.
Like a cosmic kitchen.
Hydrogen becomes helium.
Helium becomes carbon.
Carbon becomes oxygen.
Each [music] step builds something new.
And then comes iron.
Iron [music] cannot burn.
It only absorbs energy.
The moment [music] an iron core grows at the heart of a star, everything stops.
Gravity [music] wins.
The core collapses in less than 1 second.
>> [music] >> The explosion that follows seeds the universe with everything [music] that star built.
The oxygen you are breathing right [music] now was forged inside a dying star.
The calcium holding your bones together.
The iron at the center of this planet generating [music] the magnetic field that keeps life possible on the surface.
You are not separate [music] from the universe.
You are what the universe made from its own wreckage.
Every [music] breath is proof that a star gave >> [music] >> everything it had.
