Physicists have spent decades treating mass as something particles simply possess, a built-in feature explained by the Higgs field but not fully illuminated by it. A new wave of research is now ...

In three-dimensional particle physics, elementary particles divide nicely into fermions and bosons. But in lower-dimensions, things aren't so clear cut. These dimensions host a "third kingdom" of ...

A new theory proposes that the universe’s fundamental forces and particle properties may arise from the geometry of hidden extra dimensions. These dimensions could twist and evolve over time, forming ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Time is the strange dimension: Unlike its spatial siblings, it is a one-way street as the clock only ever ticks forward and never backward. Scientists have long been aware of time's quirks, with the ...

It might sound like something from The Matrix, but scientists now say that our universe has seven dimensions. In addition to the four dimensions we normally experience – height, length, depth, and ...

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 ...

When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain. Ordinary matter, the stuff we can see and touch, accounts for just ...

In one of the most memorable interviews of my career thus far, I was at my desk, head in my hands, talking on the phone to a physicist about extra dimensions. I was trying to understand what it means ...
