Space–time collision Artist’s impression of a black-hole binary system generating gravitational waves. The black holes will eventually merge, and this latest research could improve our understanding ...

Exactly 99 years after Einstein’s theory of general relativity was proven right in our own solar system, scientists show that it also holds true for entire galaxies.

Under certain extreme conditions Einstein’s general theory of relativity seems to violate determinism, according to an international team of physicists. The group has shown that in a universe ...

Albert Einstein opened humankind’s eyes to the universe. Before Einstein, space seemed featureless and changeless, as Isaac Newton had defined it two centuries earlier. And time, Newton declared, ...

"I do not consider the main significance of the general theory of relativity to be the prediction of some tiny observable effects, but rather the simplicity of its foundation and its consistency," ...

On January 14, 2025, the Laser Interferometer Gravitational-wave Observatories (LIGOs) recorded a cosmic tremor unlike any before. Named GW250114, the signal was the ‘loudest’ gravitational wave ...

In my previous article we discussed the “who, what, when, where and how” of the worldwide gravitational wave detection effort. The observant observer will have noticed we’re still missing the “why”.

This video summarizes quantum gravity, highlighting the conflict between general relativity and quantum mechanics. It ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the physicist ...
