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

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

To summarize, string theory says that there are 11 dimensions. We know of 4 physical dimensions, and there are in addition 7 other dimensions.

String theory says we may be living in a universe where reality meets science fiction: A universe of 11 dimensions, with parallel universes right next-door. An elegant universe composed entirely ...

String theory has long been presented as physicists' best candidate for describing the fundamental nature of the Universe. Yet, at the beginning of the 21st century, it became apparent that most ...

However, for more than 40 years now, there has never been found a single piece of experimental data that can only be explained by string theory. String theory cannot explain anything better than the ...

Current versions of string theory require 10 dimensions total, while an even more hypothetical über-string theory known as M-theory requires 11.
