It might sound like science fiction, but the three dimensions of space we are used to might not be the only ones out there. One theory of particle physics suggests there are in fact nine dimensions, ...

The existence of parallel universes has long been one of the biggest mysteries of the universe. Now, scientists believe they have found a way to some day detect hidden dimensions. Physicists think ...

Why does string theory require 10 or 11 spacetime dimensions? The answer at a technical level is well-known, but it's hard to bring it down to earth. By reading economics blogs by people who check out ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...

Lisa Randall, one of the world's most influential physicists, explains why we need more than three dimensions to understand the cosmos Scientific progress always entails an almost contradictory set of ...
