Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

Physicists are close to performing the most accurate tests of Einstein’s ideas about gravity ever undertaken. Their first-of-its-kind experiment involves using two kinds of extremely cold atoms aboard ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

You've probably heard this sort of claim before: Einstein made a prediction, usually with general relativity, and we're just now getting around to testing it. It's a slightly misleading idea, since ...
