While still theoretical and highly debated, the mathematics of string theory suggests that there could be multiple dimensions of time.

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.

The reason strings are such a hot topic nowadays, Jones explains, is that the new theory not only helps to solve some long-standing problems in physics, but it also attempts to explain other, not ...

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.

However, string theory requires the existence of additional spatial dimensions beyond the three we know. These extra dimensions are compactified, meaning they are curled up on themselves at scales so ...

String theory presumes the existence of extra spatial dimensions. How do we know they exist? It must be so because it is so deeply embedded in the mathematics and not easy to explain.

A simulation of the early universe using string theory may explain why space has three observable spatial dimensions instead of nine. The leading mathematical explanation of physics goes beyond ...

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 ...

String theory cannot explain anything better than the SM. A proposed experiment to test string theory would cost more than the annual GDP of the entire planet to construct.

My colleagues and I used to worry that a theory of these quantum phases of matter would forever elude us. That was before we learned about string theory. Tangled Up in Strings ...
