If it is not about the complex rules of quantum physics, we will not have formed neutral atoms “only” ~ 380,000 years after the big explosion.
To exist, a lot of things should have occurred. The planet Earth needed to appear, while completing the organic ingredients from which life can arise. In order to obtain these ingredients, we need many previous generations of stars that lived and feeding, with the recycling of the elements that were formed inside them to the middle between the stars. In order for these stars to live, large quantities of neutral molecular gas had to collect in one place, and it collapsed under its weight to a part of the shrapnel and the formation of the stars in the first place. But in order to make those stars – even the first stars – we first need the universe to create stable and neutral atoms.
In the universe that begins with a large hot blow, this is not necessarily easy! A few minutes after the big hot explosion, our world was full of protons, a small number of more complex atomic cores, an equal number of electrons to the total number of protons, a large number of neutrons that do not interact with any of them, and about 1.4 billion photons per proton or present. (There is also a dark matter …
