Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could ...

New DESI-inspired research suggests dark energy may evolve over time and cross the mysterious "phantom divide," potentially ...

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, ...

For most of modern cosmology, scientists have worked with a surprisingly simple assumption: the mysterious force driving the ...

Scientists now have a clearer understanding of when and how the Universe could ultimately reach its final, inevitable end.

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 ...

Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively ...

Elucidating the origin of recent tensions between probes of the early and late Universe could lead to a new understanding of gravity on the largest scales. Could Albert Einstein ever be proven wrong?

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 ...
