No person cares about any neutrinos, one who is not a physique does not even know what they are, but I like to put them in conversations every now and then. Think, for example, that each of your centimeters of skin is crossed every second by billions of neutrinos, who cross you and the entire planet as if there was nothing. You will say well, so what? They interact very little with the subject, for this reason it is so difficult to reveal them. They almost have no mass, “almost” but not zero like a photon.
But the secrets of the universe, of the infinitely large, move from the study of the infinitely small, from the elementary particles. In short, I wanted to inform you that the scientists caught the most energetic neutrino ever “seen”, 220 billion of electronvolt, which being a writer and not a physique I would not know how to quantify you.
Know that it is a very powerful neutrino. It had been revealed in 2023 by the Arca detector of the submarine telescope for neutrinos Km3net and the results of the analyzes of the event called KM3-230213 ° (I know, these names always seem passwords) have finally been published on Nature). The km3net telescope (still under construction) is huge, at 3450 meters deep off the coast of Portopalo di Capo Passero, in Sicily.
The neutrinos, I said, are messengers of important information from the most remote places in the universe and with the most extreme phenomena such as supernove explosions, flashes of gamma rays, the growth of supermaxicci black holes in the center of the galaxies. From this neutrino, and from others that will be detected, we will find other answers to many questions.
Don’t worry, nothing reassuring. Although I always fall asleep by listening to conferences on black holes: no time, no space, collapsed matter, they are fascinating. Among other things, I have always used elementary particles as a healthy alibi for my misanthropy, so as not to leave the house: they come from space, and the space is carcinogenic.
Only in the Marvel comics do you become superhero with gamma rays.
I know, the physicists assure you that we are protected from the earth’s magnetic field, and the atmosphere, and in any case it is not a roof on the head that would protect me, even if I lived in a lead bunker. But now I have a new excuse: hey, guys, have you heard of high energy neutrino? I don’t want to go out.
