On Wednesday, a team of researchers announced that they were very lucky. The team is building a detector on the floor of the Mediterranean Sea that can identify those rare occasions when a neutrino happens to interact with the seawater nearby. And although the detector was only 10 percent of the size it will complete, he managed to pick up the most energetic neutrino that has ever been detected.
For the context, the most powerful particle acceleration on Earth, the great Hadron Collider, accelerates protons into an energy of 7 Tera-Electronvolts (TEV). The detected neutrino had an energy of at least 60 PETA electron volts, possibly 230 pev. That also blew away the previous records, which were near 10 PEV.
Attempts to trace the Neutrino to a source make it clear that it originated outside our Milky Way, although there are a number of sources of candidate in Lake Far Universe.
Looking for Neutrinos
Neutrinos are, as far as they are famous, famous because they don't want to communicate with anything. They rarely encourage regular matter that it is estimated that you need about a light year to completely block a clear source of it. Each of us has dozens of trillions of neutrinos that go through us every second, but less than five of them actually interact with the matter in our body in our entire life.
The only reason why we can detect them is that they are produced in miraculous quantities by nuclear reactions, such as the merger that takes place in the sun or a nuclear power plant. We also pile up the deck by ensuring that our detectors have a lot of matter available for the neutrinos to communicate with.
One of the more successful implementations of the “Much Matter” approach is the Icecube detector in Antarctica. It trusts the fact that neutrinos that come out of space will create many particles and light when they hit the Antarctic ice cream. So a team drilled in the ice and set series detectors to pick up the light, so that the arrival of neutrinos can be reconstructed.
