What a Neutrino Actually Is, According to Quantum Physics

#neutrino #quantumphysics #particlephysics Right now, hundreds of trillions of tiny particles are flying through your body. Every second. They left the heart of the Sun about eight minutes ago, and they will keep going, straight through the Earth beneath your feet. They are called neutrinos. For decades, physicists believed they weighed nothing at all. However, quantum physics tells a far stranger story. A single neutrino carries three different masses at the same time, and it changes identity as it flies. Today we chase these ghosts. We climb into a gold mine hiding a giant tank of cleaning fluid, stare into a buried cube of Antarctic ice, catch one particle carrying the energy of a falling ping pong ball, and hunt a sea of ancient ghosts left over from the first second of the universe. If this kind of journey is your thing, tap like and subscribe, so you never miss the next one. Take a breath. We begin.
