I'm still highly confused about the weak force. Every time I read about it I get something along the lines of it is responsible for beta decay which to my understanding is when a proton or a neutron exits from the atom's nucleus. One thing I have trouble understanding is that if the strong force is pulling protons and neutrons together what stops them from being totally next to each other unable to move closer together due to the Pauli Exclusion Principle? Is it because the strong force pulls protons and neutrons together, while the weak force pulls them apart, creating an equilibrium? I sort of doubt that given that the strong force is 40 orders of magnitude stronger than gravity and the weak force is only 25 order of magnitude stronger than gravity. So getting back to the weak force, what would happen if it did not exist? It doesn't seem to be that important. I'm pretty sure the Sun's energy is caused by the weak force but I'm not exactly sure how. I've also heard that magma bursting up through the Earth's fault lines has something to do with the weak force.
