In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and ...

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 ...

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

Albert Einstein is famous for his contributions to physics, even predicting this strange and fascinating gravitational effect ...

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 ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window ...

In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their ...

A research team proposes utilizing numerical relativity, a computational technique for solving Einstein's equations in high-gravity environments, to investigate the universe's origin. The approach ...
