- Neutrino - Wikipedia
A neutrino ( njuːˈtriːnoʊ new-TREE-noh; denoted by the Greek letter ν) is an elementary particle that interacts via the weak interaction and gravity [2][3] The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero

Neutrinos are therefore the most penetrating of subatomic particles, capable of passing through an enormous number of atoms without causing any reaction Only 1 in 10 billion of these particles, traveling through matter for a distance equal to Earth’s diameter, reacts with a proton or a neutron

Neutrinos are denoted by the Greek symbol ν, or nu (pronounced “new”) But not all neutrinos are the same They come in different types and can be thought of in terms of flavors, masses, and energies Some are antimatter versions There may even be some yet undiscovered kinds of neutrinos!

Neutrinos are tiny subatomic particles, often called 'ghost particles' because they barely interact with anything else Neutrinos are, however, the most common particle in the universe

Neutrinos are the most abundant particles that have mass in the universe Every time atomic nuclei come together (like in the sun) or break apart (like in a fission reactor or particle accelerator), they produce neutrinos

In 1930, physicist Wolfgang Pauli proposed the existence of neutrinos to explain the energies of electrons emitted in radioactive decays In those decays, called beta decays, one nucleus converts
