Neutrino very unusual or first index of the mysterious dark matter? An event detected by a “neutrino detector” in 2023, and initially attributed to an “impossible” neutrino, could have been something much more intriguing.
The particle in question, detected by a machine called KM3NET, was an energy level so high – 35 times more than the most powerful neutrinos ever detected – that it was difficult to classify as a neutrino. But it was the only plausible explanation two years ago.
In addition, this new machine, located at the bottom of the Mediterranean near the Italian coast, and which is not even fully operational yet, is specifically designed to detect high -energy neutrinos (km3net means Cubic Kilometre Neutrino Telescope).
But now, physicists suggest that it could not have been a neutrino, but a particle of dark matter, that is to say a type of particle which is still completely unknown to us.
Underestimable mass
We know that the dark matter exists because a part of the total mass of the universe is still undetectable to us, but a possibility to explain the fact that it is undetectable to us could be that it is hidden at energy levels which are still out of the reach of our technologies.
