The video mentions that this image was taken during the night time. If the neutrinos do not interact with the entire Earth on their way through, then how do they interact with the sensor?
Thanks. I watched half the video, but couldn't finish it. Now that I've finished it I see that the neutrinos interact with water in the tank.
Thirty interactions on average per day, that's crazy - earlier in the video the host mentions that the cross section of a thumbnail has a billion neutrinos flowing through every second!
