Scientists in Greece have laid out a mathematical framework to help explain a so-far-unsolved gap in our understanding of how gravity scales up to the full size of our universe. Specifically, ...

Churning nano-wormholes could explain the clash in our cosmological constants. The wormholes add magnitude to a math parameter called the Gauss-Bonnet term. Boosting one term in a complex equation ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The widely accepted theory at the present moment ...

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize ...

PROVIDENCE, R.I. [Brown University] — The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It’s also the source of one of ...

General Relativity continues to provide a robust framework for understanding the interplay between gravitational waves and the cosmological constant. Gravitational waves—ripples in the fabric of ...

Do constants of nature—the numbers that determine how things behave, like the speed of light—change over time as the universe expands? Does light get a little tired traveling vast cosmic distances? It ...

The conclusion of DESI's first survey marks an important milestone for cosmology, which finds itself in a bind for the best reasons.
