The LIGO-Virgo-KAGRA collaboration has released 161 new gravitational wave detections, bringing the total confirmed signals to 390 and more than quadrupling the count from before the fourth observing run. The catalog includes evidence for second-generation black holes, the sharpest gravitational wave signal ever recorded, and an independent measurement of the Hubble constant — while debate intensifies over whether next-generation detectors will render current infrastructure obsolete within a decade.
