Elusive ‘Geoneutrinos’ Are Building a New Map of Earth’s Volatile Interior
“Splashdown,” Depatie says over a radio as he steps into an inflatable raft waiting below.Normally, the cavern is one of the darkest places on Earth, but today it is lit up for maintenance, offering us a rare chance to see inside. I peer through the hatch at Depatie as he paddles over to examine the submerged experiment. He’s inspecting a house-sized detector built to catch some of the most elusive particles known to physics: neutrinos.This is the SNO+ neutrino experiment, buried deep within the Creighton mine at Snolab, an underground physics laboratory in Sudbury, Canada.
