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 ...

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 ...

Could the universe have hidden dimensions we’ve yet to detect? The idea of extra dimensions has intrigued physicists for over a century, and while there’s no solid evidence to prove their existence, ...

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, ...

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 ...

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 ...

One of the weirdest theories in cosmology is the holographic principle, the idea that our universe is a three-dimensional image projected off a two-dimensional surface — the idea that, yes, we are ...
