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 ...

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 ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

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

One hundred years ago today, in the wake of the first World War, a British astronomer watched a solar eclipse for signs that a German physicist may have been right about warps in the universe. The ...

(Inside Science) — Just six years ago, scientists with the Laser Interferometer Gravitational-Wave Observatory, or LIGO, in Louisiana and Washington measured a unique undulating signal when the ...

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 ...
