Gravitational wave detector confirms theories of Einstein and Hawking
"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout."
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is celebrating 10 years of cutting-edge gravitational wave science by confirming predictions made by physics luminaries Albert Einstein, Stephen Hawking and Roy Kerr — and potentially revealing a path toward a theory of quantum gravity. "This gave us an unprecedented opportunity to put Einstein's theories through some of the most rigorous tests possible — validating one of Stephen Hawking's pioneering predictions that when black holes merge, the combined area of their event horizons can only grow, never shrink." "The detection of a black hole binary with parameters similar to those of GW150914, but three times louder, only a decade after the breakthrough discovery, is owed to the tremendous technological improvements of our instruments, paving the path for precision astronomy with gravitational waves," said LIGO-Virgo-KAGRA collaboration team member Patricia Schmidt, Associate Professor at the University of Birmingham.
