Albert Einstein's theory of general relativity has been proven right again — and this time, physicists have pinned down just how precise it is: Any deviations from his theory of general relativity are ...

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and ...

The basic idea is to fire coherent pulses of cold atoms upwards and then let them fall. Discussions linking quantum theory and gravity can be traced at least back to Einstein, who famously argued that ...

General relativity describes gravity as the curvature of spacetime induced by matter and energy. Exact solutions of the Einstein field equations play a central role in elucidating phenomena ranging ...

Answering some of the biggest questions in astrophysics—for example, about black holes and the origin of the universe—might require overhauling general relativity. In this artist’s illustration, ...

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.

This November, Einstein’s theory of general relativity will celebrate its 100th anniversary. Despite its advanced years, Einstein’s soon-to-be centenarian theory is holding up remarkably well. That’s ...

ALBERT EINSTEIN’S contributions to modern physics are unmatched, but his stellar reputation rests above all on a theory he presented to the Prussian Academy of Sciences in Berlin in a series of ...

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1915. It unifies special relativity and Sir Isaac Newton's law of universal gravitation with the ...
