At the South Pole, 5,160 glass sensors sit up to two and a half kilometres beneath the ice, waiting for particles that have crossed billions of light-years. This is the story of IceCube, an idea that almost nobody believed would work, and the discovery that won the 2026 Nobel Prize in Physics.
We follow Francis Halzen’s “unreasonable” idea from Pauli’s ghost particle in 1930, through the near-failure of AMANDA, to the first high-energy cosmic neutrinos in 2013 and the blazar TXS 0506+056 on 22 September 2017. Along the way: why a muon outruns light in ice, and how a detector made of ice reads direction and energy.
