For instancr like neutron decaying into proton electron and antineutrino. I read it in a book that says that according to Fermi, each of these particles are vibrations in different quantum fields and that each field exerted a tiny influence on the others. Because of quantum mechanics, we cant percieve the gradual transfer; we observe the neutrons and we either see it as a neutron, or we see that its decayed with some probability that can be calculated. Is this the reason? If is so, I dont really get what it means.
