One of the biggest challenges in modern physics is uniting quantum mechanics and general relativity. A new experiment may ...

A novel theory of "wavy space-time" suggests the division between our best descriptions of the universe on its smallest and largest scales may be because gravity does not play by quantum rules.

General Relativity reinterprets the force of gravity not as a traditional force but as a manifestation of the curvature of spacetime. Its formulation rests on a rigorous mathematical framework ...

In 1919, a total solar eclipse allowed scientists to confirm Einstein’s theory of general relativity by observing how the sun’s gravity bent starlight. This discovery revolutionized physics and made ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny ...

In pure general relativity, with no other modifications or considerations of other physics, they remain black for eternity. Once one forms, it will just hang out there, being a black hole, forever.

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 ...

Test of general relativity by a pair of transportable optical lattice clocks. Nature Photonics, 2020; DOI: 10.1038/s41566-020-0619-8 ...

Einstein's theory of general relativity called the weak equivalence principle, which states that all objects, regardless of their mass or composition, should free-fall the same way in a particular ...

Atomic clocks measure Einstein's general relativity at millimeter scale Date: February 16, 2022 Source: National Institute of Standards and Technology (NIST) Summary: Physicists have measured ...

The tale of how British astronomers proved Einstein’s general theory of relativity to be correct during a total solar eclipse is well known, and yet the received wisdom among scientists is that ...

Ever since the 1919 eclipse, Einstein's general theory of relativity has consistently held up, and largely been accepted, but the final proof didn’t come until much more recently when on ...
