“Surprisingly, we found that even significantly higher dark energy densities would still be compatible with life, suggesting we may not live in the most likely of universes,” said Durham University’s ...

Dark energy makes up roughly 70% of the universe, yet we know nothing about it. Around 25% of the universe is the equally mysterious dark matter, leaving just 5% for everything that we can see and ...

DESI maps distant objects to study dark energy. The instrument is installed on the Mayall Telescope, shown here beneath star trails. The fate of the universe hinges on the balance between matter and ...

In 2024 a shockwave rippled through the astronomical world, shaking it to the core. The disturbance didn’t come from some astral disaster at the solar system’s doorstep, however. Rather it arrived via ...

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 ...

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 ...

In 1998, astronomers discovered dark energy. The finding, which transformed our conception of the cosmos, came with a little-known consequence: It threw a wrench into the already daunting task of ...

Imagine stepping into a machine, pressing a few buttons, and emerging in a different century. What once existed purely in the imagination of science fiction authors is now increasingly entering the ...

The Dark Energy Spectroscopic Instrument used millions of galaxies and quasars to build the largest 3D map of our universe to date. Combining their data with other experiments shows signs that the ...
