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 ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Physicists are increasingly entertaining a radical possibility: our familiar universe of three dimensions of space and one of ...

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

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 ...

Positive curvature, like that on a sphere, implies a finite universe, while zero curvature, as on a flat plane or negative ...
