Gravitational Lensing May Turn GW231123 into an Ordinary Black-Hole Merger

A new study suggests GW231123's 'impossible' mass may be due to gravitational lensing, which would mask a final black hole of about 140 solar masses as about 225 solar masses. If true, the event would fit existing black-hole formation models and avoid the pair-instability mass gap, but the lensing explanation is not yet proven and remains a caveat rather than a confirmed cause. Gravitational-wave lensing could become a valuable tool for future discoveries.

Cosmic Lens Could Rewrite a Massive Black-Hole Merger

A Space.com report notes researchers modeling the GW231123 gravitational-wave event suggest the unusually high inferred masses of the merging black holes could be an illusion caused by gravitational lensing. If a foreground object (roughly 190–850 solar masses) or a globular cluster lenses the signal, the true masses could be around 140 and 100 solar masses, avoiding the need for extreme spins. The lens’s exact nature remains unknown, and confirming lensing in future events will require more sensitive detectors; the team published their findings in Astrophysical Journal Letters.
