The physicists of the MIT confirm observationally the theorem of the region of Stephen Hawking

Back in 1971, Stephen Hawking proposed to make the theorem of the region with black holes. The theorem of the Hawking area predicted that the total area of ​​the black hole event horizon should never decrease. MIT physicists have now observed observationally that the theorem for the first time. The study shows evidence on the basis of gravitational waves to show that the total area of ​​a black hole event horizon can never decrease. 

Although many on black holes is a mystery, central law predicted that black holes should never be able to reduce the area of ​​their event horizon. The event horizon is the limit beyond which nothing can escape the gravitational traction of the black hole. The law is described as the theorem of the Hawking area, and five decades after Hawking proposed the theorem, it has now been confirmed for the first time.

In the study, the researchers at the MIT and elsewhere watched the GW150914, which is the first gravitational wave signal detected by the 2015 laser interferometer gravitational wave observatory. The signal was produced by a pair inspiring black holes that have generated a new black hole and a massive amount of energy. The researchers say that if the theorem of the Hawking area holds, the Horizon area of ​​the new black hole should not be less than the total horizon area of ​​the parent nero holes.

In the study, the signal was reanalyzed before and after the cosmic collision and physicists found that the total event horizon area did not decrease after the merger. The team says they have 95% of confidence in their conclusions. The results marked the first confirmation of direct observation of the Theorem of the Hawking region, which had already been proven mathematically but never observed in nature.

The project researchers intend to test future gravitational wave signals to see if they also confirm Hawking’s theorem. Isi Maximiliano researcher says it’s not something you’re trying once, and it’s over. Test once is only the beginning.
