Extra dimensions, if they exist, would not just be a science‑fiction flourish but a structural feature of the cosmos that could help explain gravity, quantum mechanics and even why the universe looks ...

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 ...

Some scientists think quantum mechanics may be working in a lower-dimensional setting, giving us the illusion of our 3-dimensional universe. This idea changes the nature of our perceived reality, ...

Space and time looked settled, at least in broad outline. Einstein's special relativity gave physics a durable framework for describing motion, and for more than a century one boundary seemed firm: ...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...

The book Flatland: A Romance of Many Dimensions by Edwin A. Abbott explores the concept of physical dimensions through characters who encounter higher-dimensional beings. The protagonist, “A. Square,” ...

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 ...

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...
