The Event Horizon Telescope only recently gave us the first images of the environment immediately surrounding a black hole.

The EHT captured a surprising polarization reversal around M87*, pointing to rapidly changing magnetic fields near the black ...

The historic first image of the Messier 87 (M87) supermassive black hole, captured using the Event Horizon Telescope, has ...

"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

New data reveals black hole jets can accelerate at speeds defying all physical laws, leaving astronomers without a clear ...

In 2017, the EHT collaboration yielded the first-ever image of a supermassive black hole at the center of the Messier 87 ...

Physicists developed a method to test Einstein’s general relativity precisely where black hole shadow images reveal potential differences under alternative gravity theories. This simulation explores ...

At the center of a galaxy 10 billion light-years away, a supermassive black hole is the new record holder for brightest flare ...

Black hole images may test competing gravity theories. A new method uses simulations to check if they follow Einstein or alternatives with future sharper telescopes.

Researchers are using black hole “shadow” images to test whether Einstein’s relativity remains unshakable. With next-generation telescopes, they hope to spot telltale signs of alternative physics ...
