A Major Prediction Stephen Hawking Made About Black Holes Has Finally Been Observed


A Major Prediction Stephen Hawking Made About Black Holes Has Finally Been Observed
observational confirmation of one of Stephen Hawking s predictions about black holes.
An analysis of the very first gravitational wave detection made back in 2015, GW150914, has confirmed Hawking s area theorem. It states that, under classical physics, the area of the event horizon of a black hole can only grow larger - never smaller.
 
The work gives us a new tool for probing these mysterious objects, and testing the limits of our understanding of the Universe.
It is possible that there s a zoo of different compact objects, and while some of them are the black holes that follow Einstein and Hawking s laws, others may be slightly different beasts, said astrophysicist Maximiliano Isi of MIT s Kavli Institute for Astrophysics and Space Research. ....

Physicists observationally confirm Hawking's black hole theorem for first time


Massachusetts Institute of Technology
There are certain rules that even the most extreme objects in the universe must obey. A central law for black holes predicts that the area of their event horizons – the boundary beyond which nothing can ever escape – should never shrink. This law is Hawking’s area theorem, named after physicist Stephen Hawking, who derived the theorem in 1971.
Fifty years later, physicists at MIT and elsewhere have now confirmed Hawking’s area theorem for the first time, using observations of gravitational waves. Their results appear today in Physical Review Letters.
In the study, the researchers take a closer look at GW150914, the first gravitational wave signal detected by the Laser Interferometer Gravitational-wave Observatory (LIGO), in 2015. The signal was a product of two inspiraling black holes that generated a new black hole, along with a huge amount of energy that rippled across space-time as gravitational waves. ....
