    We May Finally Have a Way to Detect Hawking Radiation Leaking From Black Holes

    The article goes into Hawking radiation from black holes.

    Score one for Stephen Hawking! We may have just discovered a quantum gravity observation. I'm hoping that this physics discovery will help us along with the quantum study of gravitation.

    I have been following news about black holes since about 2014. It was January 2014 that Hawking came out with a paper entitled "Information Preservation and Weather Forecasting for Black Holes" and you can view that here: https://arxiv.org/abs/1401.5761

    Then, in the following years, Hawking, and others, came up with the idea that black holes have soft hair. Black Hole Entropy and Soft Hair: https://arxiv.org/abs/1810.01847

    Also, some time in between Hawking was headline news that there are no black holes. What he really meant was that there is no event horizon in black holes, just an apparent horizon (https://en.wikipedia.org/wiki/Apparent_horizon).

    So, that was what Stephen Hawking was working on before his death in 2018.

    Now, a new team, Niayesh Afshordi, an astrophysicist at the Perimeter Institute and the University of Waterloo, thinks he has discovered Hawking radiation (https://www.vice.com/en_us/article/...black-holes-could-soon-change-physics-forever). If this can be verified it would be the smoking gun that Hawking radiation is real and black holes dissolve over time. That black holes are quantum in nature. And, even, that escape from any point in a black hole is possible.
