In this video, we break down the theory of general relativity, revealing how mass and energy bend the fabric of space and time. Discover how this groundbreaking theory explains everything from the way ...

General relativity and changes in Mercury's orbit The orbit of Mercury is shifting very gradually over time due to the curvature of space-time around the massive sun, according to NASA.

In General Relativity, we treat space and time as continuous, but all forms of energy, including but not limited to mass, contribute to spacetime curvature.

Albert Einstein's theory of general relativity has held up pretty well after a century out in the world.

General relativity is distinguished from other metric theories of gravitation by its use of the Einstein field equations to relate spacetime content and spacetime curvature.

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 ...

Brief history of "dark energy" The idea of dark energy is as old as general relativity itself. Albert Einstein included it when he first applied relativity to cosmology exactly 100 years ago.

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

There are new hints that the fabric of space-time may be made of "memory cells" that record the whole history of the universe. If true, it could explain the nature of dark matter and much more ...

General relativity tells us that gravity is not a force, but a curvature of spacetime. A century ago this year, a young Swiss physicist, who had already revolutionized physics with discoveries ...
