    you have a 1 in 4 chance of being struck by a neutrino during your lifetime. this will cause you absolutely no harm, and you will not notice it, but it's pretty neat regardless.

      Only 1 in 4 of it ever happening to you? I thought it would more common than that.

        About yeah. The interaction rate of neutrinos is incredibly low for the garden variety the sun is constantly hitting you with. You can actually take a photo of the sun through the earth with neutrinos because of how little the interact. The superkamiokande experiment did it most recently I think. On average, an electron neutrino will go a light-year through lead before interacting.

          Oh so it’s still passing through you, just not hitting any of your matter? Somehow that makes both more sense and less.

            No don't misunderstand, there's a 1 in 4 chance it will hit your matter in your lifetime. There's millions of them constantly passing through you all the time.

              Yeah, the latter is what I was thinking initially, so it makes more since that they are passing through you like I thought. But at the same time being bombarded with millions of particles and none of them actually hitting your matter is pretty insane.
