Neutrinos

• Neutrinos – what are they like?

  • ALMOST NEVER interact with matter
    • 100s of trillions of neutrinos pass through you every second!
    • An inch of lead stops an X-ray, but you need a slab of lead more than a light-year thick to stop a neutrino
  • Pass almost DIRECTLY out of Sun!
  • IF we could detect them, they would tell us about the conditions at the CENTER of the SUN!

• Detecting Neutrinos:

  • RARELY: Chlorine + neutrino  Argon
