i have a bit of an interest in particle physics, however im by no means smart or uni educated. so try to keep your answers in laymans terms. im curious about something. as human knowledge progresses, we learned about the atom, and then electron proton neutron. and then photons. however im assuming beyond that is theoretical? lets say if god or ghosts exist, would they have to consist of something? meaning as humans learn, can we eventually know and prove the smallest building blocks so the we essentially know or become god? so if string theory eventually becomes common knowledge for us, and this turns out to be the universes absolute smallest building block, would that mean that we would have the knowledge to prove or disprove god, or know what a ghost is. would it be that no knowledge is beyond us? or are the smallest building blocks so small that we could never ever know whet they are?
