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, ...

In a groundbreaking exploration of physics, researchers have revealed a way to extend Albert Einstein's special theory of relativity to accommodate superluminal observers—those moving faster than ...

The largest-ever three-dimensional map of the cosmos, plotting out some 15 million celestial objects, could help reveal the ultimate fate of the universe. Astrophysicists know that the universe is ...

It is believed that matter, motion, gravity, and everything else we know of originated from the three dimensions of space and one of time. However, a new idea challenges this theory, suggesting that ...

A three-dimensional brane represents one possible state of 3D space at a specific instant — a snapshot of the universe. As time ticks by, it generates a collection of branes, like the successive pages ...
