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 …

Jan 23, 2026 · 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 …

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. …

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 …

Sep 21, 2022 · 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.

Sep 7, 1999 · Neutrinos are one of the most abundant particles in the universe. Because they have very little interaction with matter, however, they are incredibly difficult to detect.

Jan 21, 2026 · 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 …

Apr 2, 2025 · Neutrinos are elementary particles that belong to the family of leptons, which also includes electrons, muons, and taus. Unlike other particles, neutrinos have no electric charge and interact …

Jul 13, 2022 · Neutrinos travel at speeds approaching the speed of light. A neutrino only reacts to gravity and the weak nuclear force (weak interaction). Because of this, it very rarely interacts with matter. …

Furthering our understanding of neutrinos and their properties could provide tremendous insight into the fundamental makeup of our universe. Researchers working at the frontiers of physics are making …
