Physicists wowed by record-shattering neutrino detection

It was the biggest shot with the smallest ammunition.Somewhere far beyond our galaxy, something endowed a single neutrino – a tiny subatomic particle – with 10,000 times the energy achievable in the most powerful particle accelerator on Earth. After crossing millions of light years of intergalactic space, the neutrino smacked into our planet, jettisoned a second particle and rang one the world’s largest experiments like a carnival strongman wielding a sledgehammer.
