Jan 27, 2022 at 18:10 comment added WarpPrime The protons end up colliding, forming helium-2, which almost instantly decays into deuterium. It's not random smashing of protons making one of them turn into a neutron. It is very hard for loose protons to come together and stick, they tend to just dissociate instead of stick and decay into deuterium
