Albert Einstein postulated in his 1905 theory of special relativity that the speed of light in a vacuum is constant. Ever ...

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

Growing lettuce, taming fire, chilling atoms to the coldest point in the universe and hunting for invisible matter… The ...

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?

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.

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...
