Could the universe have more dimensions than we realize? (Image credit: Getty Images) String theory is a purported theory of everything that physicists hope will one day explain … everything.

Scientists have long sought evidence to refute string theory, but a new test seeks to disprove key aspects with help from the ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

Researchers in Japan have developed what may be the first string-theory model with a natural mechanism for explaining why our universe would seem to exist in three spatial dimensions if it actually ...

According to string theory our universe has ten dimensions: three spatial dimensions, one time dimension and six dimensions which are possibly rolled up into thin cylinders.

The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be ...

Oh, and this imagined world has 11 dimensions, not the four dimensions – up/down, left/right, backwards/forwards and time – we have in our so-called real world.

String theory suggests that vibrating strings that exist in 10 dimensions underpin the observable Universe. Although that basic premise is still very much in doubt — and as yet impossible to ...

The theory failed to unite gravity and quantum mechanics. But it still has become one of the most useful tools in science.

We live in a three-dimensional universe (four if we include the dimension of time). However, string theory proposes that there are a total ten different dimensions (11 total, including time).
