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.

1999年9月7日 · A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero.

2011年1月25日 · Neutrinos are teeny, tiny, nearly massless particles that travel at near lightspeeds. Born from violent astrophysical events like exploding stars and gamma ray bursts, they are fantastically...

2022年9月21日 · Neutrinos are tiny subatomic particles, often called 'ghost particles' because they barely interact with anything else. Neutrinos are, however, the most common particle in …

2025年3月1日 · neutrino, elementary subatomic particle with no electric charge, very little mass, and 1/2 unit of spin. Neutrinos belong to the family of particles called leptons, which are not subject to the strong force.

2022年7月13日 · A neutrino is a subatomic particle and also an elementary or fundamental particle. In other words, it is smaller than an atom and does not consist of smaller subunits. It …

The neutrino is perhaps the best-named particle in the Standard Model of Particle Physics: it is tiny, neutral, and weighs so little that no one has been able to measure its mass. Neutrinos are the most abundant particles that have mass in the universe.

2022年6月15日 · Of all the elementary particles in the universe, neutrinos may be the strangest. Sometimes known as “ghost particles,” these mysterious little packets of energy have no electrical charge, have...

3 天之前 · In the vast and complex realm of physics, few particles have captured the imagination of scientists and laypeople alike like neutrinos. These elusive, nearly massless subatomic particles travel through space…

A neutrino is a particle! It’s one of the so-called fundamental particles, which means it isn’t made of any smaller pieces, at least that we know of. Neutrinos are members of the same group as the most famous fundamental particle, the electron (which is …
