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

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

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 ...

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.

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

The Standard Model of our universe doesn’t match the evidence, in part because of dark energy, a ghostly force pushing the ...

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 ...
