String theorists are betting that extra dimensions do indeed exist; in fact, the equations that describe superstring theory require a universe with no fewer than 10 dimensions.

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there ...

Why physics suggests other dimensions exist Theoretical physicists point to the idea that there are other dimensions out there, beyond what we can see. And there could be loads of them, as Melissa ...

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.

If Extra Dimensions Do Exist, They Must Be Really, Really Small. News. ... Many of these ideas predict that other dimensions exist, and these could be probed by gravitational waves.

String theorists are betting that extra dimensions do indeed exist; in fact, the equations that describe superstring theory require a universe with no fewer than 10 dimensions.

As such, they do not place any constraints on the 10-plus dimensions predicted by string theory — a theory in physics that suggests everything is made up of tiny vibrating strings.
