What can we learn from neutrinos?
Neutrinos are by far the most abundant particles in the universe. Neutrinos also provide a tool to study the structure of nucleons (protons and neutrinos), to learn how matter evolved from simple particles into more complex composites of particles, creating everything around us.
What is one of the key goals of the dune experiment?
Fermilab will shoot the world’s most intense beams of neutrinos and antimatter neutrinos through both detectors to better understand a fascinating behaviour called neutrino oscillation. One of the key goals is to see if neutrinos and antimatter neutrinos oscillate identically.
Do photons and neutrinos interact?
Since neutrinos do not carry electric charge, they don’t interact, directly, with photons. Neutrinos do carry weak charge-that’s how they interact directly with other particles and, thus, with photons. An electron-neutrino, for example, can emit a virtual electron and a virtual W boson.
Can neutrinos be used as a medium for communication?
The answer is, technically, yes, there is no physical law preventing the use of neutrinos as a communication medium. It has been demonstrated that we can cause the emission and detection of neutrinos. For example, neutrino emissions have been detected from a nuclear reactor at a distance of 1 km in this paper.
Why is a neutrino-based computer impossible?
There are several reasons why a neutrino-based computer is impossible. Neutrinos interact very weakly with matter. Billions of them fly through your body every single second without any interaction. This makes it difficult to detect or guide them along a desired path (like a wire).
Can we detect neutrinos here on Earth?
Although neutrino-based systems have been proposed here on Earth since the 1970s, they have all come up against the same problem: how to detect the neutrinos at the receiving end when the vast majority of the particles will pass straight through any detector.
How do submarines detect neutrinos?
Submarines therefore have to float a wire antenna to the surface, which restricts their speed and depth, making them easier to detect. For ease of transmission through any material including seawater, nothing beats the neutrino. The ghostly particle is affected only by the weak nuclear force and, very faintly, by gravity.
