The universe, cooled enough to let quarks form protons, neutrons and let electrons go in tracks round the nucleus.
But what kind of atoms where there atm. Mostly there where Hydrogen the easiest of them all. 1 proton and 1 electron obiting its nucleus. A tiny bit of Helium and a little less some lithium.
These where the first 3 elements which existed all there before suns even existed.
But now, there are 3 forces which describes the nucleus and how Electromagnetics work. The 4th Force is gravitiy which lets 2 masses attract each other. Yes i know Einstein did a kind of new theory of gravity but that doesnt work on atomic level.
Real big masses of gases will attract each other or forming Spheres, you may ask why spheres we live in 3 Dimensions plus the time and the easiest contribution of a force in a 3 dimensional room is a sphere, if we would have instead of spheres cubes, some parts of the cubes wouldnt be attract with the same force than right in the middle of a side.
Real big masses of Gas seem to form big globes of matter. Which is kind of awesome if you think twice about it.
Now there is a little problem, we know from Electromagnetic rules that the same charges wont attract each other, so what does that mean for our spheres full of hydrogen for example.
At a tiny level, the nucleus would repel from other nucleuses. You cant do anything against it, the funny thing is, since something like a nucleus has matter, it also has energy and if you go for the Potential pot (linearer Potential Topf ger), youre able to see that even behind the bars there is a little possibility for the nucleus to be outside its own pot, and there must be kind of neighbor pot where sits another proton, sice we got to deal with only hydrogen ^^, they might to get in contact with eachother then the weak nuclear force gets in action and holds the 2 protons together.
We now had a quanttunneling effect for the hydrogen nucleus. And we formed 2 Hydrogennucleuses into a Deuterium Isotope, it has the twice amount of masse because of these 2 protons in the nucleus but should have only 1 electron.
Now go further this tunneleffect happens again and we get into Tritium another isotope. But what can also happen, the nucleus could let one Proton turn into a neutron which is slightly lighter, and releases the restmass in form of elemtparticles neutrinos positrons etc ...
If we repeat the procces for example 1 H + 1 H = 2H ( Deuterium) 2H + 1H =3H Tritium
3H + 3 H = 4 He + 1H + 1H, its just an example but from 2 Tritium we got 1 Helium atom with 2 Hydrogen nucleuses, and that is what makes Nucleusfusion, all the stars are doing it and our Sun aswell. That happens because of Gravitiy force on the atoms and the atoms which do fusion like radiate energy from them in terms of thermoenergy, they radiate heat like a piece of burning wood.
from 3 He nucleuses we can get one C atom which is kind of a Basement atom of life, after Carbon there can be N-atom and afterwards an O-atom which is our air we breathe and in the end make up water an so on. The last Element which can be fused like this is Fe, thats Iron and The earliest Stars have like no Iron in them at all, why, it didint existed before them. Now we got Like Hydrogen atoms, Lithium ,Helium, Carbon, Nitrogen, Oxygen, Silicon and Iron.
All the other elements which are heavier than Iron, made afterwards, when the earliest Suns have died and spread all their fused atoms and a few nucleuses which didnt made into fusion processes, in german terms its called Neutroneneinfan- prozess.
With the Infos about the first stars we now can say, since were made out of carbon and hydrogen based molecules, were stardust or atomic sun trash ^^.
With these words we will go tomorrow to the next episode of all our history.
