For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials that were theorized to exist only in four-dimensional ...

What would the universe be like if it had four spatial dimensions instead of three? Experimentalists are starting to explore the physics of higher dimensions with the help of recently developed tricks ...

A team of international researchers has shown that four-dimensional structures can influence the mechanical and topological ...

This method maps our usual four-dimensional physics into a five-dimensional gravitational model, where Einstein’s equations can be used more directly. It’s not science fiction—it’s a mathematical ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...

To square Albert Einstein’s General Theory of Relativity with quantum mechanics requires some currently unknown physics, and that’s led some scientists to question if Einstein’s theory could use some ...

Natalie Paquette spends her time thinking about how to grow an extra dimension. Start with little circles, scattered across every point in space and time—a curlicue dimension, looped back onto itself.

In a significant development in the field of superconductivity, researchers have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) ...
