In their study, scientists propose using fingerprints of atmospheric neutrinos in so-called
Every moment the Earth is bombardedcosmic rays. Most of them consist of light nuclei and protons. And when these rays pass through the atmosphere, some of them collide with atoms, breaking them into pieces and leading to the formation of neutrinos. As a result, they “rain” on the planet. Astrophysicists believe that studying the history of this bombardment will provide more data about the sources of cosmic rays. In this new study, scientists suggest that rocks deep below the Earth's surface may contain such "recordings." Scientists plan to extract part of this rock for study.
The team conducted experiments to find outwhether traces of collisions of neutrinos with cosmic rays can be found in various types of rocks. Using computer simulations, scientists have found that these tracks are between 50 and 100 micrometers in size. Accurate data on the range of trace sizes will allow you to examine the samples you need. However, researchers warn that mining them will take some effort. Traditional excavation methods can damage specimens.
