General relativity revealed that space and time are linked in a flexible four-dimensional fabric that is bent and indented by matter. In this picture, Earth orbits the sun because it is caught in ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

A network of Earth's best clocks will be synchronised with the most accurate one ever sent into space. But the device has a ...

General relativity revealed that space and time are linked in a flexible four-dimensional fabric that is bent and indented by matter. In this picture, Earth orbits the sun because it is caught in ...

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 ...

For the first time, a mathematical framework proves that Einstein’s theory of general relativity, which explains the ...

Developed in 1915, general relativity suggests that gravity arises because bodies with mass cause the fabric of spacetime (the four-dimensional unification of space and time) to warp. The greater ...

Quantum ideas describe particles and fields in tiny packages, but general relativity paints gravity as smooth curves in space‑time. Until now.

After seeing these comments by Schmidt, I reasoned that the former Google executive might have bought Relativity Space as a ...

On 25 November 1915, Albert Einstein presented his general theory of relativity at the Prussian Academy of Sciences. This theory is still considered to be the most important idea in modern physics.

Tim Ellis, cofounder and CEO of Relativity Space, is competing against SpaceX in the booming space launch business and reinventing manufacturing in the process. Relativity CEO Tim Ellis on the exc ...
