The universe may be vast, but researchers have multiple points of evidence that reveal its shape.

How can the behavior of elementary particles and the structure of the entire universe be described using the same mathematical concepts? This question is at the heart of recent work by the ...

Dimensions beyond the four we’re familiar with could solve a host of problems in physics and cosmology. Columnist Leah Crane ...

Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown.

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

For measuring curvature of 3D (hyper) surface we need solid angles instead of plane angles. General relativity (GR), which explains events on the greatest cosmological scale, and quantum mechanics (QM ...
