The Ghost Particles Streaming Through You Right Now

Because neutrinos possess no electrical charge and negligible mass, they rarely collide with atoms, earning them their spectral reputation. While light from the Sun struggles to escape its dense core, neutrinos exit almost instantaneously, carrying unadulterated data about their origins. Physics professor Michael Pravica of the University of Nevada notes that their ability to ignore obstacles makes them unique messengers from the deep cosmos.

First theorized in 1930 and finally detected 26 years later, these particles remain notoriously difficult to trap. Current research, supported by the US Department of Energy, focuses on fundamental questions: determining their precise mass and identifying whether a neutrino acts as its own antiparticle. Solving these puzzles could explain why the universe is composed of matter rather than antimatter, potentially revealing why the anti-matter produced during the Big Bang vanished entirely.
