Firing a high-energy neutrino beam into a Cepheid could heat its core and brighten the star early -- "just as an electric pulse to the heart can make it skip a beat," Learned says.
The neutrinos could be made by blasting a proton beam at a target -- sapphire, carbon or tungsten would work, says Learned. The target produces subatomic particles, mostly pions, which decay to produce neutrinos.
The normal and shortened pulses could be used to encode data, to form what the researchers call a 'galactic Internet' in a paper posted to the arXiv preprint server.
