Two-year observing run detects 250 gravitational-wave mergers, confirms Hawking prediction
The world's gravitational-wave observatories completed a two‑year run capturing 250 new black‑hole and neutron‑star mergers — over two‑thirds of all detections to date. The dataset provides the first direct evidence for Hawking’s 1971 black‑hole area theorem, reveals second‑generation black holes and the most massive merger observed.
