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

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

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.

Here’s what you’ll learn when you read this story: Theoretical physicists believe math shows the possibilities of a fourth dimension, but there’s no actual evidence—yet. Albert Einstein believed space ...

Florida physicist has suggested that two of the biggest mysteries in particle physics and astrophysics — the existence of extra time and space dimensions and the composition of an invisible cosmic ...
