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.

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

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

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 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.
