What the Most Massive Black Hole Merger Reveals About Cosmic Limits

What occurs when the universe plays a cosmic curveball, breaking down long-standing assumptions about how black holes form? On 23 November 2023, the LIGO-Virgo-KAGRA Collaboration observed a gravitational wave signal GW231123 that would become an instant classic in the field of astrophysics.

Gravitational shockwave: LIGO catches a 225-solar-mass black-hole smash-up

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123. The record-setting blast strains both the sensitivity of LIGO-Virgo-KAGRA and the boundaries of stellar-evolution theory,

What LIGO's Second Gravitational Wave Discovery Means For Science

And LIGO’s second gravitational wave event, GW151226, is great for both! Essentially, on the pessimist’s side, GW151226 makes it all-but-certain that LIGO is picking up genuine gravitational ...
