Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and ...

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 ...

Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

For over a century, physicists have been trying to answer one of the most profound questions in science: Can gravity be unified with the quantum world? While the main model describes the ...

To live on the moon or Mars, humans will need heat and air conditioning that can operate long term in reduced gravity and temperatures hundreds of degrees above or below what we experience on Earth.

Big G, gravity, is the oldest fundamental constant in physics and the least clearly defined. One scientist has spent a decade attempting to crack the mystery.

Antimatter — the mysterious substance that's the mirror opposite of matter in most ways — falls downward in gravity like everything else in the universe, a team of physicists reported Wednesday in the ...

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 ...
