Physicists have successfully developed a new instrument that significantly reduces quantum-level noise that has thus far limited experiments’ ability to spot gravitational waves. Collisions between massive black holes and stars are thought to generate these ripples in space-time that were first detected in 2015. In all, about 11 detections have been fully confirmed so far.
