Prof. David Kaiser and graduate student Alexandra Klipfel speak with New York Times reporter Dennis Overbye about their theory that a neutrino detected zipping through the Mediterranean Sea in February 2023 may have come from an exploding primordial black hole. “Dr. Kaiser and Ms. Klipfel concluded that if primordial black holes were the explanation for long-sought dark matter, scientists should expect about 40 black-hole explosions to occur each year in every cubic light-year near the Milky Way,” Overbye notes. “You’ll never, ever hope to see Hawking radiation if the only black holes ever were ones that formed from dead stars,” says Kaiser. Primordial black holes have different masses and different lifetimes, he noted: “Some go bang right now.”
