In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And while we haven't found any evidence yet for anything outside our normal ...

We all know we live in three-dimensional space. But what does it mean when people talk about four dimensions? Is it just a ...

Restricting a strange class of particles known as anyons to one dimension could force them into adopting one of two new forms, models suggest, hinting at new fundamental interactions in particle ...

Mathematicians say knots cannot exist in four-dimensional space because the extra dimension allows a rope to move around itself and untangle, revealing surprising insights into geometry and topology.

Could the universe have hidden dimensions we’ve yet to detect? The idea of extra dimensions has intrigued physicists for over a century, and while there’s no solid evidence to prove their existence, ...

Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one. In everyday ...

Physicists are scrambling to understand why dark energy is weakening. In a surprising twist, we must now reconsider the ...

A group of researchers from Virginia Tech are attempting to find a fourth spatial dimension of the universe. If they succeed, their discovery would literally change how people view the world. "Since ...

BUFFALO, N.Y. -- Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues ...

Ever wondered what four dimensions really mean? Discover why knots can’t exist in 4D space — and how mathematicians use cubes and clever analogies to understand higher dimensions.
