For more than a century, physicists have suspected that the familiar three dimensions of space might be only a small slice of reality. The idea that the universe could be hiding several additional ...

Scientists studying dark matter have published new findings based on a warped extra dimension model that suggests particles in a fifth dimension.

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 ...

In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

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 ...

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, ...

BUFFALO, N.Y. -- Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues ...
