This question already has an answer here:
So, I have been reading about connection of particle physics and thermodynamics of early universe. Like after big bang, and quark - gluon plasma etc..
Anyway, after 1 second after big bang, the ratio of proton and neutron was around 7; which means there were a lot of more protons, rather then neutrons.
And this is also a reason which helped later nucleosynthesis. So, my question is what are the reasons here why there was a bigger number of protons, from neutrons.
Should I watch it here from the perspective are protons and neutrons stable? Is the same like radioactive decays?
