One hundred years ago this Wednesday, Albert Einstein gave the last of a series of presentations to the Prussian Academy of Sciences, which marks the official completion of his General Theory of ...

General Relativity, Einstein’s revolutionary theory of gravity, reinterprets gravitational interactions as phenomena emerging from the curvature of spacetime rather than as forces in the traditional ...

Editor's note: Scientists said today that after more than a half-century search, they have finally detected gravitational waves — the ripples in the fabric of space-time that Albert Einstein predicted ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

Pedro Ferreira looks back at how Einstein himself and a panoply of other physicists have framed the theory. Until very recently, relativists were few and often self-taught. General relativity still ...

From smashing particles together to analyzing the properties of a supermassive black hole, much of physics research takes place far beyond the realm of our everyday experience. However, there is one ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Scientists may be celebrating the 100th anniversary of Albert Einstein’s general theory of relativity, but there was also a death in 1915. It was one of the many deaths of simple and intuitive physics ...

A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...

It was 1905, and Albert Einstein had just turned theoretical physics on its head by publishing a paper on what later became known as special relativity. This showed that space and time could not be ...
