IF ALIENS have built a massive collider to smash particles together, a new detector could soon pick up the signs.
Most searches for ET focus on radio signals. But Zurab Silagadze at the Budker Institute of Nuclear Physics in Novosibirsk, Russia, points out that we could pick up signs of neutrinos created by our alien neighbours’ science experiments. Here on Earth physicists are pondering building accelerators that could reach higher energies by smashing together muon particles. “If we have thought about developing muon colliders, aliens – if they exist – could have too,” says Silagadze.
Such muon colliders would create an…
