Neutrino Signals Detected at Large Hadron Collider
Neutrinos are fundamental particles of the universe, meaning that they are not made up of any smaller components as far as we know. Scientists have been hunting neutrinos for years, and special detectors have confirmed their presence before. It's thought that if physicists can learn more about them, they can answer some of the most pressing questions in physics—such as why we live in a universe of matter and not antimatter. But neutrinos are notoriously elusive. This is in part because they are incredibly small and light, with a mass hundreds of thousands of times less than that of an electron—which itself is hardly gigantic. This means that they pass through almost everything they encounter. It's thought that trillions of them are passing through our bodies and out the other side every single second. We know that some neutrinos are created in the heart of the sun, and others should also be created when the LHC smashes particles together. But to date, sc...
