Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively simple question: why? One answer, first sketched a century ago and refined ...

Besides the basic well-known states of matter – solid, liquid, gas and plasma – there are many exotic states being conjured up in the lab. One of these, known as a “supersolid,” was only confirmed a ...

When you drill down into the very fabric of reality—where elementary particles make up the matter that is you and me and everything around us in three-dimensional space—things get divided nicely into ...

Dimensions beyond the four we’re familiar with could solve a host of problems in physics and cosmology. Columnist Leah Crane ...

Physicists are increasingly entertaining a radical possibility: our familiar universe of three dimensions of space and one of time might be only part of a larger structure, with a hidden fifth ...

In the photonic synthetic dimension, the coupling of internal degrees of freedom of photons, such as frequency, spatial mode, and orbital angular momentum, generates extra dimensions in addition to ...
