In this video, we venture beyond the known limits of our universe and explore the mind-bending concept of the Tenth Dimension ...

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

But when we look around the universe, we only ever see the usual three spatial dimensions plus the dimension of time. We're pretty sure that if the universe had more than four dimensions, we would ...

These hidden dimensions could hold the key to unifying physics, from gravity to quantum mechanics. Little Boy Cares For ...

They suggested that the early universe—which exploded from a single point and was very, very small at first—was one-dimensional (like a straight line) before expanding to include two dimensions (like ...

It's not yet clear whether we can go from, say, a ten-dimensional String Theory to a three-dimensional Universe like our own and have them be dual to one another.

Linked loops face the same problem in three-dimensional space but become free of the constraint when there are more dimensions, like the 10 posited by string theorists.

They believe the way our universe started and then diluted as it expanded – what they call the relaxation principle – favored formation of three- and seven-dimensional realities.
