Room-sized “atom waves” could help probe the quantum realm

Researchers are preparing to scrutinize nature at tiny scales by stretching supercooled atoms into room-length waves as they drop them down a 100-meter vacuum tube. By exploiting the atoms’ wavelike properties, the experiment will look for ripples in the bizarre quantum realm: potential fingerprints of missing dark matter and, in future iterations, new frequencies of gravitational waves.
