  I read this in the voice of Todd from Project Farm

  Any idea of what they are looking into? I always thought neutron detectors were for detection of nuclear activity.

    Here are some neat neutrino facts:

    • Neutrinos are incredibly difficult to detect.
    • There are many neutrino sources, although supernovae may be the most prevalent with 99% of energy released as neutrinos vs 1% as visible light.
    • Our sun radiates about 2% of its energy as neutrinos.
    • They travel at the speed of light and rarely interact with normal matter. So rarely, in fact, that 99.99% of neutrinos would pass through a 10km-thick slab of lead.
    • Most neutrinos pass through the entire earth without hitting a thing.
    • 10^21^ nuetrinos pass through each 1" x 1" area of your body per second and, on average, you have a 25% lifetime chance of interaction with a neutrino particle.

    Who knows what will be discovered!

      That’s exciting!

      Iirc there are some unsettled theoretical questions about the nature of reality and the cosmos that would possibly be answered by studying the behavior of neutrinos, but I forget what.

      I can feel all those neutrinos on my body

    These are neutrino detectors, not neutron, so they won’t be looking for nuclear activity with it, right?

      Nuclear reactions do involve neutrinos and antineutrinos but they aren’t super important for fission so I am assuming the decade long detector would be for something else

    No sorry, I have to wait for the video. 👍
