Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

On the very smallest scale, the world is mysterious and counter-intuitive. At this level, things simply don't work the way you'd expect them to, and quantum mechanics is our best attempt at applying a ...

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 ...
