The results reveal that our universe is reverberating with cosmic collisions. Some of the waves stem from pairs of black ...

Decades in the making, a space probe that delves into Albert Einstein's general theory of gravitation remains grounded on Earth, caught in its own space-time continuum of technical snags, costly ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

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 ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

Gravity doesn’t discriminate. An experiment in orbit has confirmed, with precision a hundred times greater than previous efforts, that everything falls the same way under the influence of gravity. The ...

The tiny bots follow patterns of light and "artificial space-time," navigating like craft following the curved space around a ...

On Aug. 21, the continental U.S. will be treated to a total solar eclipse that will dazzle the nation as it progresses from coast to coast, starting in Oregon and ending in South Carolina. The event ...
