The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

Engineers have found a way to shepherd microrobots with no wires, no radios, and no onboard computers. Instead, they steer them with light patterns designed using the same math physicists use to ...

Astronomers have finally watched a black hole do something Albert Einstein only described on paper: twist the very fabric of ...

In the mid-19th century, Bernhard Riemann conceived of a new way to think about mathematical spaces, providing the foundation ...

Contemporary physics has learned to describe the universe with unprecedented precision. Yet when it tries to say what time is, it stumbles again and ...

A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

Dustin Henderson and the rest of the squad in Stranger Things get a pretty decent briefer on wormholes by his science teacher ...

The Princeton that Albert Einstein knew in 1933 was sharply divided by the color line; a long-established border—marked by ...

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

Scientists are a step closer to solving one of the universe's biggest mysteries as new research finds evidence that two of ...

General relativity describes gravitation in a geometrical framework generalizing special relativity and classical mechanics. This term includes theoretical studies of gravity, experimental studies of ...
