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 ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

String theory unifies all the forces of nature. Forces that seem very different, such as gravity and electricity, are deeply ...

Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, ...

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

In Interstellar, Miller’s planet orbits close to the black hole Gargantua, where gravity is so strong that time runs much slower. This is gravitational time dilation, a prediction of Einstein’s ...
