After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest ...

There was a secret inside the envelope in the hands of Stephan Schlamminger, one of the world’s leading experts in experimental tests of gravity. He appeared to be on the verge of opening the envelope ...

A study of 300,000 galaxies confirms that gravity follows Newton's law and deepens the mystery of dark matter.

A NIST researcher has unveiled the results of a 10-year quest to measure the gravitatinal constant., which determines the strength of the attraction between two masses anywhere in the universe.

The time had come to open the envelope, but Stephan Schlamminger, a physicist at the National Institute of Standards and ...

Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and ...
