General relativity is an astonishingly beautiful theory, and grappling with why it disagrees with quantum mechanics is a joy, ...

A tiny but radical twist in the fabric of the cosmos could offer a breakthrough in one of astronomy’s most persistent ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

Einstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research shows ...

Offers new possibilities to control light across the spectrum and insight into light–matter interactions. The device, reported in Advanced Photonics, functions as an optical black hole or optical ...

Quantum theory and general relativity in fact don’t get along at all. The two theories generally work at very different scales, so that’s not a huge problem. But it prevents us from ...

In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending ...

A team of physicists have discovered a new approach that redefines the conception of a black hole by mapping out their detailed structure, as shown in a research study recently published in ...

A juvenile colossal squid was spotted in its natural environment alive at a depth of almost 1,100 feet, according to the ...

On 25 November 1915, Albert Einstein presented his general theory of relativity at the Prussian Academy of Sciences. This theory is still considered to be the most important idea in modern physics.

In the early 20th century, Albert Einstein’s theory of general relativity revolutionised our understanding of gravity, but did it truly replace Isaac Newton’s timeless laws? Newton’s law of ...
