That's an insane amount of energy. If your are knowledgeable about this do you know why some neutrinos have more energy than others? surely it is just a relationship with it's s…

Neutrinos are very weakly interacting and hence you need a massive amount of some matter through which they can pass so as to have a decent probability of getting an interaction…

Huh? Here are all the headlines currently above the fold on the homepage. Don't see anything about a drag queen below the fold either. Maybe something autocorrected in your addr…

Since neutrinos don’t interact with much of anything, its path doesn’t deviate from its origin. Different origins emit neutrinos with different levels of energy. When a neutrino…

A neutrino is an elementary particle that interacts via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero. The rest mass of the neutrino is much smaller than that of the other known elementary particles . The weak force has a very short range, the gravitational interaction is extremely weak due to the very small mass of the neutrino, and neutrinos do not participate in the electromagnetic interaction or the strong interaction. Consequently, neutrinos typically pass through normal matter unimpeded and with no detectable effect. Read more on Wikipedia
