Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...

The video explains how Albert Einstein moved from special and general relativity to a search for a single framework tying ...

An analysis of a record-breaking gravitational-wave detection tests whether general relativity holds under extreme conditions. A year ago, the LIGO-Virgo-KAGRA Collaboration recorded the clearest ...

Einstein's theory of general relativity holds that a massive body like Earth curves space-time, causing time to slow as you approach the object—so a person on top of a mountain ages a tiny bit faster ...

Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure ...

In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and acceleration. Initially ridiculed, Einstein developed key concepts after observing a ...

Wormhole time travel is mathematically valid under general relativity, but exotic matter, stability, and quantum gravity gaps ...

A timelines of the life and career of Albert Einstein, including his theories of special and general relativity.

A recent theory of gravity has stimulated intense debate and many explorations of its implications. There is, however, an example that served as a model for Hořava’s theory. The example, due to ...
