What are Neutrinos?

Oct. 1, 2024

Researchers exploring neutrinos in dense environments like supernovae and neutron star mergers discovered that these “ghost particles” can become entangled, sharing quantum states and evolving chaotically.

About 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. 
  • Approximately 100 trillion neutrinos pass completely harmlessly through your body every second.
  • Their tendency not to interact very often with other particles makes detecting neutrinos very difficult.
  • Neutrinos have no charge; they are neutral, as their name implies.
  • They belong to the family of particles calledleptons, which are not subject to the strong force. 
  • Neutrinos don't interact at all with the strong nuclear force that binds atomic nuclei together, but they do interact with the weak forcethat controls radioactive decay. 
  • Neutrinos come from all kinds of different sources and are often the product of heavy particles turning into lighter ones, a process called “decay.”
  • Neutrinos are created by various radioactive decay, such as during a supernova, by cosmic rays striking atoms, etc.
