The universe is expanding and that expansion is accelerating under the power of dark energy and eventually all matter and energy will be dispersed over such unthinkable distances that nothing can stop ...

New hints from one of the most extensive surveys of the cosmos to date suggest that mysterious dark energy may be evolving in ways that could shift how astronomers understand the universe. Dark energy ...

The universe's expansion may be accelerating faster than previously thought. Dark energy, a mysterious force, might not be constant but could be changing over time. Multiple independent studies show ...

One of the greatest mysteries in cosmology is the nature of what we refer to as dark energy. This mysterious force drives the expansion of the universe to accelerate. Dark energy is an unknown ...

“Dark energy” is a term scientists use to refer to whatever is causing the universe to expand faster over time. We don’t know exactly what dark energy is—no one has ever directly seen or measured ...

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy Spectroscopic Instrument (DESI)—namely that the dark energy, rather than being ...

Welcome to the age of precision cosmology, a scientific era in which astronomers and physicists have measured almost everything about our universe—except for its deepest mysteries: dark matter and ...

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 most widely accepted theory currently suggests ...
