"I Thought It Would Fail!" Francis Halzen: Winner of the 2026 Nobel Prize In Physics [Reupload from 2022]

The physicist who turned a cubic kilometer of Antarctic ice into a telescope says the most exciting moment of his career was not the discovery. It was the first atmospheric neutrino. Before that, he was deep in debt to NSF and his own university with no neutrino to show for it.

Francis Halzen is principal investigator of the IceCube Neutrino Observatory at the South Pole and Hilldale and Gregory Breit Distinguished Professor of Physics at the University of Wisconsin-Madison.

We cover: why ice under the South Pole is clearer than anything a lab can make, the 2,600 TeV event that dwarfs the LHC, why IceCube sees more energy in cosmic neutrinos than in gamma rays, how neutrinos crossing the universe test quantum gravity, and the quark he refused to believe in.

Physics is a miserable career unless you are obsessed by it.

Recorded in 2022, before IceCube detected neutrinos from our own galaxy.
