The new experiment could help to find neutrinos using radar echoes, One of the great mysteries of astrophysics today is small subatomic particles called neutrinos, which are so small that they can enter the atmosphere, our bodies and the earth itself without matter being discovered.
For decades, physicists around the world have been trying to find neutrinos that are constantly bombarding our planet and which are lighter than other known subatomic particles.
Scientists hope that by capturing neutrinos, they can learn them and hopefully understand where they come from and what they do.
However, existing experiments are often expensive and skip entire high-energy neutrino classes from some outer space.
These neutrinos are elementary particles that we don’t understand. And very high-energy neutrinos can tell us about a large part of the universe that we cannot access.
This study is based on a phenomenon known as a cascade. Scientists estimate that they move neutral across the earth at nearly the same speed of light. Billions of them now occur when you read this. The new experiment could help to find neutrinos using radar echoes.
Higher-energy neutrinos tend to collide with atoms. This collision creates a cascade of charged particles like giant sprays. And the cascade is important: if researchers find the cascade, they can detect neutrinos.
High-energy neutrinos are so rare that scientists have so far been unable to find them.
Scientists have found that the best neutrino detection location is in the large ice sheets: the longest running and most successful neutrino experiment conducted in Antarctica.
Radio waves are the cheapest known neutrino detection technology, researchers say, which is part of the reason why it is so interesting. Radio waves have been used in the search for the highest-energy neutrinos for around 20 years. The new experiment could help to find neutrinos using radar echoes.
This radar technology could be another tool in the radio wave box for scientists who want to study neutrinos with very high energy.
A better understanding of neutrinos can help us understand more about our galaxy and the entire universe.
Neutrinos are the only particles that are known to move along straight lines that directly penetrate objects, say researchers.
No other particle does this: light is blocked. Other charged particles are deflected into a magnetic field.
When neutrinos are made anywhere in the universe, they continue to move in a straight line. Researchers say: This points back to what was produced. So this is a way to identify this very energetic process in the universe and learn more about it.
