Astronomers have proposed that gravitational lensing — the warping of light and other signals by massive objects — may explain why GW231123 appeared to involve unusually large black holes. The signal was detected in November 2023 [livescience.com][gandul.ro]. GW231123 was described as the most massive black hole merger detected to date, but the apparent masses of its component black holes were difficult to reconcile with existing expectations for black hole formation. The lensing proposal could account for the unusual measurement but raises a separate question about a previously unobserved type of spacetime distortion [livescience.com][google.com].
