Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, ...

Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

Some string theorists predict at least 10 dimensions, most of which humans can’t perceive. | Andriy Onufriyenko/Moment/Getty Images Ask someone to name every ...

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 experience three spatial dimensions in nature: length, width and height. In addition, we perceive time as a fourth dimension. But some theoretical physicists have speculated that “extra” spatial ...

When someone mentions "different dimensions," we tend to think of things like parallel universes – alternate realities that exist parallel to our own, but where things work or happened differently.

Our brains may not be equipped to picture 10 spatial dimensions, but see if you can get to at least four here. For most of us, or perhaps all of us, it's impossible to imagine a world consisting of ...
