proton magnetism and repulsion

Question

I am reading that it is proton magnetism that keeps us from falling through a bed if we land on it- That is to say that the proton magnetism in the bed repulses the protons in us, our clothes etc. If proton magnetism rejects nearby protons due to their magnetism why don't all of our proton rich cells simply fly apart?

Answer 1

In everyday matter around us, individual protons are fixed inside the nuclei of the constituent atoms. They cannot do free streaming inside everyday materials. There are two fundamental interactions that keep our nuclei stable: electromagnetic interaction (keeping electrons inside their orbits around nucleus) and strong interaction (keeping nucleons from disintegration). But the first one is many orders of magnitude smaller than the second one. In small scale, We need both of them to survive.

Again, the use of everyday is crucial here as you want to break the matter apart; first you can remove electrons by low-energy ionization and then separate individual protons by high-energy collisions. But, no matter what is the amount of energy, you will never have energy enough to break protons into their constituent particles (gluons and quarks) for a considerable time duration due to confinement. However, we believe that this was easily achieved in early Universe where it is thought infinite amount of energy was somehow reached for a very very very small fraction of time.
