Learn how researchers used Einstein’s theory of general relativity to create the most accurate simulations to date.

Today marks the centenary of an experiment which proved Albert Einstein's theory of general relativity - but what exactly is that theory? Dr Matthew Bothwell, an astronomer at the University of ...

Researchers at TU Wien have integrated quantum physics with general relativity, revealing significant departures from ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window into the universe’s most extreme events. These collisions not only revealed ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

Scientists have discovered gravitational waves stemming from a black hole merger event that suggest the resultant black hole settled into a stable, spherical shape. These waves also reveal the combo ...

Albert Einstein’s general theory of relativity has been wildly successful at describing how gravity works and how it shapes the large-scale structure of the universe. It’s summed up in a saying by the ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

In October 2015, a young mathematician named Clemens Sämann was flying home to Austria from a conference in Turin, Italy, when he had a chance encounter. He found himself seated beside Michael ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

The second image of the supermassive black hole in M87 was taken by the Event Horizon Telescope shows it still has a shadow just as Einstein predicted. When you purchase through links on our site, we ...
