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.

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

A groundbreaking discovery in the realm of physics has scientists abuzz with the potential confirmation of a portal to other ...

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

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

Discovering extra dimensions with the relatively huge size of a few micrometers would offer spectacular confirmation for string theory, the still unproved body of equations that may unify gravity ...

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

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 ...

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.
