An international team, spearheaded by Prof. Luciano Rezzolla at the Goethe-Universität, has invented a novel approach to ...

Black holes, regions of spacetime in which gravity is so strong that nothing can escape, are intriguing and extensively ...

The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

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

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

Albert Einstein changed science forever with special and general relativity, redefining space, time, and gravity. Yet after his greatest triumphs, he became obsessed with something even bigger — a ...

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 ...

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 ...

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

The project involved observing a massive, fast-spinning star called a pulsar, and its companion white dwarf - a smaller but very dense star that is dying, having lost most of its outer layers - doing ...

A mathematical model suggests that when a pair of black holes gets quantum entangled, this can give rise to a lumpy ...
