“Some ultra-high-energy neutrinos detected at IceCube have roughly 10 billion times the energy of a typical neutrino from the sun. One detected by a similar experiment has an energy 200 times higher than that. We don't really know where that neutrino came from,”

Fuller noted that some ultra-high-energy neutrinos detected at IceCube have roughly 10 billion times the energy of a typical solar neutrino.

“Because the interaction is so weak, neutrinos can get through almost anything,”

Fuller explained that because the weak interaction is so weak, neutrinos can pass through almost anything.

“The fact that it got here at all may be saying something profound about the universe. In that sense, Halzen really is at the frontier of experimental fundamental particle physics.”

Fuller stated that the arrival of an ultra-high-energy neutrino may say something profound about the universe and that Halzen is at the frontier of experimental fundamental particle physics.

“Neutrinos are truly ghostlike particles,”

Fuller described neutrinos as ghostlike particles that are hard to stop or catch.

“Halzen's work, and the work of those he inspired with his vision, was foundational in giving humanity a new window on the universe and on the mysterious and notoriously slippery neutrino,”

Fuller stated that Halzen's work was foundational in giving humanity a new window on the universe and on neutrinos.

“It's hard to stop them. It's hard to catch them. How do we even know they exist or where they are?”

Fuller remarked on the difficulty of stopping or catching neutrinos and how we know they exist.

“Light-years of lead—depending on their energy, they would go right through it.”

Fuller noted that depending on their energy, neutrinos could go right through light-years of lead.
