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 ...

Lawrence Berkeley National Lab, or Berkeley Lab, researchers mapped nearly six million galaxies throughout the past 11 billion years of cosmic evolution using the Dark Energy Spectroscopic Instrument, ...

An international consortium of scientists studying dark energy said Tuesday their three-dimensional map of the universe over 11 billion years suggested the cosmos wasn't steadily expanding, but acting ...

Astronomers studying the largest-ever map of the cosmos have found hints that our best understanding of the universe is due a major rewrite. The analysis, which looked at nearly 15 million galaxies ...

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 ...

The Dark Energy Spectroscopic Instrument (DESI) is studying dark energy and the accelerated expansion of the universe. Dark energy is weakening and the universe could (eventually) collapse, study says ...

Dark energy, a mysterious force that scientists believe is behind the accelerated expansion of the universe, is weakening — which could result in the universe over the course of billions of years ...
