Harvard astrophysicist who wrote in 2026 that cosmic rays already surpass collider black-hole scenarios.
“Earth survived these numerous impacts throughout its 4.5-billion-year history, implying that we should not fear a black hole doomsday ... If any microscopic black holes had been produced by cosmic-ray impacts on Earth, these black holes must have evaporated rapidly without causing any harm to our environment.”
