Scientists send encoded message through rock via neutrino beam
Humankind is constantly inventing new ways to stay in touch. But in some situations it’s difficult to keep the lines of communication open. A space shuttle’s radio falls silent when the craft slips behind a neighboring planet. A submarine loses contact when deep water blocks signals from the surface.
Scientists recently proved possible a new way to converse when radio waves won’t do. For the first time, physicists and engineers have successfully transmitted a message using neutrinos.
Scientists have for decades contemplated communicating across long distances in a kind of Morse code via neutrinos, ghostly particles that interact so rarely that they can sail through the entire Earth.
“It’s beginning to look more feasible,” said electrical engineer Dan Stancil of North Carolina State University, who proposed the recent neutrino communication test as a side experiment at Fermilab’s MINERvA neutrino detector.
In the early 1980s, Stancil, who was then at Carnegie Mellon University, was intrigued by the idea of using rarely interacting particles for communication. But he was focused on axions, still undiscovered particles predicted by some theories related to dark matter. In 2009, Carnegie Mellon Ph.D. student Jim Downey contacted Stancil, his former professor, to tell him about MINERvA.

Maybe SETI should look into this. I doubt advanced alien civilizations use old fashion radio waves.
