Left panel: Frequency and decay time (half-life) of the different ringdown tones measured in GW250114. The black markers indicate the values predicted for a Kerr black hole. Right panel: gravitational ...
The “Golden Age” of Black Hole Physics It’s generally agreed that the so-called “Golden Age” of black hole theoretical physics spans from Roy Kerr’s 1963 discovery of the solution describing a ...
A decade ago, scientists first detected ripples in the fabric of space-time, called gravitational waves, from the collision of two black holes. Now, thanks to improved technology and a bit of luck, a ...
A remarkably clean gravitational-wave detection has confirmed long-standing predictions about black holes, including Hawking’s area theorem and Einstein’s ringdown behavior. The findings also provide ...
A few days ago, I wrote about non-singular black hole models, specifically one known as the Hayward model. Since its introduction in 2006, several variations of the Hayward model have been introduced, ...
