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 ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. A newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

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 ...

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

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

Netflix has released a new docudrama titled Einstein and the Bomb, that narrates the story of the German-born theoretical physicist’s life and career. Interestingly, this project used archival footage ...

In the rarefied world of theoretical physics, where Albert Einstein’s shadow still looms large, Harvard University and ...
