In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

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

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

How would Einstein have reacted to Bell’s theorem and the experimental results derived from it? Alain Aspect’s new ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

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 ...
