For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

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

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

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

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. While the ...

Researchers have demonstrated that quantum entanglement can link atoms across space to improve measurement accuracy. By ...

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

Suppose you’re a CIO or senior application planner, and you need to understand whether you should dig into quantum computing as a future option. Enterprises themselves are divided on the issue, ...

Ultracold atoms sit at the heart of the quantum-technology revolution. India has built a strong and steadily growing presence ...
