Neutrinos, the near-massless particles zipping through your body by the trillions every second, have long held secrets that could reshape our understanding of physics. The 2015 breakthrough in neutrino oscillation measurements has cracked open a door to new discoveries.

Experiments like T2K, NOvA, and Super-Kamiokande precisely tracked neutrinos as they changed their identity in flight, a phenomenon known as oscillation. This revelation is revolutionary because it challenges the Standard Model, our current understanding of particle physics.

The Standard Model predicted neutrinos were massless, but oscillation requires mass. This discrepancy indicates the Standard Model is incomplete, pointing to new physics beyond its boundaries. The implications are profound:

– Neutrinos may hold clues to why matter exists in the universe.

– They could shed light on the early universe’s asymmetry, a fundamental puzzle.

– The discovery of neutrino mass opens doors to new theories and discoveries.

The legacy of neutrino research is poised to solve one of physics’ greatest mysteries: why the universe contains matter at all. As scientists continue to unravel neutrino secrets, we’re on the cusp of rewriting the rules of physics, unlocking new understanding of the universe and its fundamental laws.
