How can they distinguish between relic, sun made and man made neutrinos? I guess our nuclear power plants also create a lot of them. (Sorry if this question is stupid or explained in the article.)mfb said:PTOLEMY is a proposed experiment to detect the cosmic neutrino background, together with a highly accurate mass measurement. Clustering is also mentioned there.
They only mention clustering in passing and cite the study I linked to, which is focused on gravitational clustering.mfb said:PTOLEMY is a proposed experiment to detect the cosmic neutrino background, together with a highly accurate mass measurement. Clustering is also mentioned there.
All of these have very different energy ranges and/or concentration depending on the placement of your detector.fresh_42 said:How can they distinguish between relic, sun made and man made neutrinos?

And type. Fission-related neutrinos are antineutrinos which don't induce tritium decay. All other sources of man-made neutrinos are irrelevant unless you build your detector deliberately in a neutrino beam (like OPERA for example) - but those have GeV energies, compared to the meV energies of cosmic background neutrinos.Orodruin said:All of these have very different energy ranges and/or concentration depending on the placement of your detector.
Neutrinos are tiny, electrically neutral particles that have a very small mass. They are one of the fundamental particles that make up the universe and are a key component of the Standard Model of particle physics.
Neutrinos are created in a variety of astrophysical processes, such as nuclear reactions in stars, supernovae explosions, and high-energy collisions between cosmic rays and atoms in the upper atmosphere.
Neutrinos are distributed throughout the universe in a process known as cosmic homogeneity. This means that they are evenly distributed on a large scale, with a density of about 300 neutrinos per cubic centimeter.
Neutrinos are difficult to detect because they interact very weakly with matter. They can pass through most materials, including the Earth, without interacting at all. This makes them challenging to detect and study.
Studying the distribution of neutrinos can provide valuable insights into the origins and evolution of the universe. It can also help us understand the properties of neutrinos, such as their mass and oscillation patterns, which can have implications for our understanding of particle physics and the laws of nature.
