Theoretically, it’s impossible for us to perceive a 4D creature. That is, unless it broke into our three-dimensional reality.

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.

The notion of dimension at first seems intuitive. Glancing out the window we might see a crow sitting atop a cramped flagpole experiencing zero dimensions, a robin on a telephone wire constrained to ...

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

In a hypertorus model of the Universe, motion in a straight line will return you to your original location, even in an uncurved (flat) spacetime. The Universe could also be closed and positively ...

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 ...

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