Just 100 years ago the young Bernhard Riemann gave his famed paper on the foundations of geometry. He discussed space of four or more dimensions, and paved the way for the General Theory of Relativity ...

Scientists have discovered a new way to probe the interiors of neutron stars by using gravitational waves to turn them into ...

he published the general theory of relativity. In it, he suggested that gravity is not a force, as Newton had believed, but the result of a curvature of the space-time continuum -- the four ...

But with general relativity, the stage itself became an active player. The amount of matter within the universe sculpts its overall curvature. And space-time itself can be either expanding or ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet ...

Gravitational physicists explore the implications of the general theory of relativity, in which gravitation is a consequence of the curvature of space and time. This curvature thus controls the motion ...

But with general relativity, the stage itself became an active player. The amount of matter within the universe sculpts its overall curvature. And space-time itself can be either expanding or ...

General relativity works well for large-scale objects ... in terms of the interactions between the energy of the field and ...

General relativity describes gravitation in a geometrical framework generalizing special relativity and classical mechanics. This term includes theoretical studies of gravity, experimental studies ...

The first is that Einstein’s general theory of relativity famously makes mass ... either in on itself like a ball (“positive” curvature) or out on itself like a saddle (“negative ...
