Neutrino detectors don’t grow on trees. Or do they? Forests could one day be used to spot ultra-high-energy neutrinos, a physicist proposes.
Trees could act as natural antennas that pick up radio waves produced by certain interactions of the difficult-to-detect subatomic particles, astroparticle physicist Steven Prohira proposes in a paper submitted January 25 at arXiv.org.
“It is a very exciting idea,” says physicist Amy Connolly of the Ohio State University in Columbus, who was not involved with the study. “This could be … a natural solution that may have been sitting there under our noses.”
