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.

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

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 ...

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 ...

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

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

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 ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...
