What does air come from?
That’s a great question….Hehehe.. therefore!!!
First of all, we need to take a closer look at the composition….Here on Earth we have the following composition.
All values slightly rounded:
Nitrogen N2 78.08%
Oxygen O2 20.95%
Argon AR 0.93%
Carbon dioxide CO2 0.04%
Neon Ne 0.001818 %
Helium He 0.000524 %
Methane CH4 0.00018 %
Krypton Kr 0.000114%
Hydrogen H2 0.000055 %
That would answer the question.But where do all these substances come from?
All these substances are incubated in stars.
After the Big Bang, there was essentially hydrogen and helium, and only as nuclei.Shortly after the Big Bang, the universe was far too hot for any electrons to somehow feel compelled to bind to an atomic nucleus. As they are, the young people… Constantly on the zwutsch.
The universe continued to expand and cool down. At some point, protons and electrons found their way into the safe haven of marriage, people I cried….
Incredible amounts of hydrogen and some helium converge into incredibly large stars.
When large stars are formed, they have a lot of mass and a lot of mass means a lot of gravity and that means that the pressure inside such stars is incredibly high.
Through this pressure, hydrogen atoms now merge into helium atoms.Imagine that the pressure must be so great that the repulsion of two protons, i.e. particles with the same charge, is overcome. The two atomic nuclei are literally baked together.
At some point, the hydrogen has completely become helium and the star now switches up a stage.Helium burning occurs. Now the burning phases are getting shorter and shorter. Helium produces carbon, then neon, then oxygen, then silicon, and then iron burning at the end. Once the star has reached the iron, it can no longer gain energy. The process has arrived after the iron at the end. This does not all happen evenly, but in shells. While a hot iron ball is already formed inside, shells still hang outside in previous firing stages. This will continue to burn as long as the radiation pressure can still preserve the shells. If the radiation pressure coincides, all shell residues fall on the inside heavy iron core and then…

At the moment of a supernova, all atoms are produced that are heavier than iron.
So what comes to mind right away. Titanium, gold, silver, molybdenum, Meitnerium, Darmstadtium, up to the Livermorium, to name but the most famous.
750,000 years before the accretion disk of our solar system formed, such a supernova took place here and ensured that today we can get all the raw materials out of the ground.And almost all the atoms needed for this have been created in a single bang.
The air, everything we exhale in and out every day, was once part of a star and then a supernova.
Otherwise we wouldn’t be.
