For more than a century, physicists have suspected that the familiar three dimensions of space might be only a small slice of ...

For more than a century, physicists have suspected that the familiar three dimensions of space and one of time might be only ...

The geometry of space, the setting in which physical laws operate, may hold clues to some of the biggest unanswered questions in fundamental physics. The underlying structure of spacetime itself could ...

Physicists have taken a bold step beyond Einstein's special theory of relativity, proposing an expansion of special relativity that includes observers moving faster than light. This fresh perspective ...

Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they ...

Some scientists think quantum mechanics may be working in a lower-dimensional setting, giving us the illusion of our 3-dimensional universe. This idea changes the nature of our perceived reality, ...

Extra dimensions may be required to explain how gravity worked in the early universe — and led to the conditions we experience today. This is the conclusion of a pair of researchers from Japan, who ...

Physicists wonder if our universe contains hidden extra dimensions. These dimensions could explain why gravity is so weak. They might be curled up so tightly we cannot see them. High-energy particles ...

When we think creatively, produce novel ideas, or otherwise have “Eureka” moments, we may actually unlock access to a dimension outside of our everyday perception, according to the controversial ...

In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And while we haven't found any evidence yet for anything outside our normal ...
