New observations of a merger of two black holes confirm decades-old predictions by Albert Einstein, Stephen Hawking and Roy Kerr. The findings emerged from analyses led by Flatiron Institute astrophysicists using the clearest measurements to date of a black hole merger taken by the Laser Interferometer Gravitational-Wave Observatory (LIGO).
In a new study published in Physical Review Letters, the LIGO–Virgo–KAGRA Collaboration has used the sharpest to date gravitational wave signal from two merging black holes to precisely test Hawking’s area theorem and the remnant black hole’s nature.
Ten years after detecting the first gravitational wave, the detection of GW250114 – a ripple in spacetime which offers unprecedented insights into the nature of black holes and the fundamental laws of physics.
