Francis Halzen has been awarded the Nobel Prize in Physics for proving that elusive “ghost particles” from space really exist.
- Halzen’s team built a massive detector buried deep in Antarctic ice, turning the continent into a giant neutrino observatory.
- The instrument captures faint flashes of light produced when high‑energy neutrinos interact with the ice.
- These observations confirm that neutrinos travel across the universe, opening a new window on cosmic events.
The breakthrough turns a wild idea into a powerful tool for exploring the hidden universe.
