Speaking of neutrinos.....
I know they interact weakly with ordinary matter....
But every once in a while one does interact.
A couple months ago one "interacted" with one of my nuts.....oh dang
that hurt !
I yelled out "Neutrino sum bitch !" and shook my fist toward the Sun
Oh sure they have almost no mass......but traveling at almost light
speed....yeah, it'll get your attention.
I now wrap my bag with aluminum foil because I'm pretty sure it'll
block neutrinos
and other signals.
