"In retrospect, the most amazing thing is that we got funded for this project." – Francis Halzen recalls greeting each milestone in the creation of the massive IceCube neutrino detector under the South Pole not with pride, but with surprise. In this conversation with the Nobel Prize's Adam Smith, recorded just after Halzen had learnt of his 2026 Nobel Prize in Physics, he speaks about the fruitful collaboration with the technical teams that built the detector. He also speculates on how neutrino astronomy promises to open up new, quite unexpected insights into super high energy processes occurring far away in space, and far back in time.
