Whats the deal with God/Ghost particles?
Usually when people talk about “ghost particles” or “ghostly particles” they mean neutrinos. But that’s just a name. Let’s come up with some operational definitions. Particle: if you can spray them, they’re particles. Electrons are the classic example. You can spray electrons from a wire just by making it hot enough; if your hot wire is in a strong electric field, all the electrons get sprayed one way. This is how the big heavy cathode-ray tube TVs work: they spray electrons at the screen, and steer them with magnets. For fun sometime, wave a refrigerator magnet near a blue-screened CRT display. The extra magnetic field will steer the electron beam from the blue to the red and green pixels. Electrons interact “electromagnetically.” If you have a beam of electrons and you put some stuff in the way, after some thickness of stuff all your electrons have stopped. There are other sorts of particles — protons, neutrons, alphas, nuclei — that interact “more strongly” than electrons. If yo
