Trillions of ‘ghost particles’ move through your body every second – but you would never know it.
Known as neutrinos, they are one of the fundamental particles that make up the universe.
They are also some of the least understood as they interact very weakly with everything else, so detecting them is difficult.
But now researchers have observed the mysterious particles changing into different states, and hope their discovery will help answer fundamental questions about our universe.
New measurements, collected at the IceCube Neutrino Observatory at the South Pole, have shed light on outstanding questions regarding properties of the mysterious neutrinos.
Reseachers at Michigan State University presented their results today at the American Physical Society Meeting in Washington.
