A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

On May 29, 1919, a total solar eclipse helped to prove Albert Einstein's theory of general relativity. Einstein's theory ...

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding ...

General relativity, Einstein's theory of gravity, is a purely classical theory that describes gravity as the warping of space-time geometry by mass and energy. But attempts to blend quantum theory ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature.

In 2015, a piece of equipment at an observatory in the US moved one quintillionth (10-18) of a meter. This tiny movement was ...

Pioneer of general relativity and gravitational-wave theories saw her work confirmed by observations 65 years later.

Fred Hoyle honored Jayant Narlikar, acknowledging his significant contributions to astronomy, particularly the Hoyle-Narlikar ...

The main idea is to have a gravity gauge theory with a symmetry that is similar to the Standard Model symmetries, instead of ...
