Gravity is the force with which we’re most familiar. It’s what’s keeping you on the planet, even as you’re reading this.

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 ...

New claims challenge inconsistencies in one of the foundational principles of physics. Albert Einstein postulated in his 1905 ...

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 ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...

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.

The Cold Atom Lab is a facility for the study of ultra-cold quantum gases in the microgravity environment of the ...

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 ...
