A wave signal from space validates Hawking’s prediction that the area of an event horizon should never decrease.
One of Stephen Hawking’s most important predictions about black holes has finally been observationally confirmed by ripples in the fabric of spacetime, reports a new study. The milestone not only validates the theories of the influential physicist, who died in 2018, it also provides a new means to test some of our most fundamental assumptions about the universe.
Black holes are famous for extremely strange behaviors, such as the capacity to trap anything, including light, inside the event horizon that marks their borders. Hawking added to this list of black hole oddities in 1971 by predicting that the surface area of the event horizon should never shrink over time, which is now known as the area theorem.
The idea echoes the second law of thermodynamics, which states that entropy can only ever increase in a closed system, providing yet another hint that black holes are important windows into broader laws of the universe.
A team led by Maximiliano Isi, a NASA Einstein Postdoctoral Fellow in MIT’s Kavli Institute for Astrophysics and Space Research, now presents the first “observational confirmation of Hawking’s black-hole area theorem” with a confidence of 95 percent, according to a study published on Thursday in Physical Review Letters. The researchers achieved this feat by closely examining the first gravitational waves ever captured on Earth, which were created by the collision of two black holes some 1.3 billion years ago.

I think that what was meant in the article is that the area of the event horizon of a black hole can’t shrink unless mass is lost. The theory is that mass can be lost through Hawking Radiation which would reduce mass over long periods of time. This while a black hole is probably gaining mass through attracting matter into the event horizon.

Scientists Confirm Stephen Hawking’s 50-Year-Old Theory About Black Holes>>>>>>>>>>>>>>
He was writing about Barack Obama.
I wonder how much guess work and wild unproven theories are involved in their “confirmation”.
Can we resurrect Hawking and give him the Nobel Prize?
Black holes are RACIST!!
Haven't you heard?
“I wonder how much guess work and wild unproven theories are involved in their “confirmation”.
If you dispute the finding present your calculations. They did.
Actually he was writing about Moochelle.
He’s too busy beyond the grave reconsidering his denial of the existence of God.
They completely ignore the most interesting implication, at least for me, which is that it’s possible for information to escape from the event horizon.
I wanna go surfing on the bitchen 1000 ft. waves of aqueous planets within the event horizon for 2 minutes to wait out Commiela’s term.
I believe such revelations from black holes will lead us to the ability to travel faster than the speed of light when man finds the earth no longer habitable.
Well, heck, Earth doesn’t do too badly on truly big waves, just not very often. Luckily.
Then there are the human assisted waves: One could ride an 820 ft. wave over a 860 ft. high dam and together slam into the valley below, taking out an estimated 2000 people with you.

We have two conflicting "Laws" from Steven Hawking. One says that black hole event horizons can only increase, the other that says they will decrease. That's not unusual in theories about things we don't fully understand, but it at least deserves a bit more discussion in an article that headlines the fact that only increases can occur.
Does taking a shortcut actually increase rate of travel?
With a lot of energy it is theorized that one could be capable of arranging the structure of space–time in the form of a soliton – a robust singular wave. This soliton would act like a “warp bubble’”, contracting space in front of it and expanding space behind. Unlike objects within space–time, space–time itself can bend, expand or warp at any speed. Therefore, a spacecraft contained in a hyperfast bubble could arrive at its destination faster than light would in normal space without breaking any physical laws— even Einstein’s cosmic speed limit. Going though a black hole might be that warp bubble and the key to greater than light travel. Men might see that in future discovery.
