Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

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 built ...

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 ...

In the present paper, we carried out a systematic investigation of pseudo-quasi-conformal curvature tensor has been made on the four-dimensional spacetime of general relativity. The spacetime ...

Two stellar mass black holes, if they merge in the vicinity of a supermassive black hole, could have their gravitational wave signal affected by the strongly curved space around them. If Einstein's ...

The supermassive black hole at the center of the Milky Way is the most extreme astrophysical object located within a million light-years of Earth. With an estimated four million solar masses, it's the ...

In 1797, English scientist Henry Cavendish measured the strength of gravity with a contraption made of lead spheres, wooden rods and wire. In the 21st century, scientists are doing something very ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...
