Pairs of black holes have been detected in the past through their gravitational effects, but until now, scientists have never ...

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

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 ...

A black hole can feel like the most distant and unreal object you could ever think about, yet the way its darkness bends ...

Black holes are considered cosmic gluttons, from which not even light can escape. That is also why the images of black holes ...

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 ...

Back on planet Earth, and deep inside a pitch-black, sulfuric cave on the Albanian-Greek border, we reported on a study that ...

Physicists have taken a new approach to whether all black holes conform to Einstein’s theory of general relativity or if ...

Interstellar object 3I/ATLAS has seemingly confirmed Einstein's general relativity by exhibiting gravitational lensing as it neared the Sun. However, the observed light bending exceeded predictions by ...

Physicists have developed a method to test Einstein's general relativity using black hole shadow images, potentially revealing different types of black holes.
