Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively ...

Geometry has surprising consequences for the behaviour of matter. Living in three dimensions, we're familiar with liquids that abruptly freeze into solids, or crystals under pressure that suddenly ...

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

For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials theorized to exist only in four-dimensional space. An ...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...

Physicists have long treated mass as a basic ingredient of nature, something particles simply possess, even as the Higgs mechanism explained only part of the story. A new wave of theoretical work now ...

Here’s what you’ll learn when reading this story: 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 ...

Ever since Einstein posited that space and time were inextricably linked, scientists have wondered where the cosmic web called spacetime comes from. When two particles are able to simultaneously and ...
