The largest-ever 3D map of the cosmos hints that the dark energy that’s fueling the universe’s expansion may be weakening. One community of theoretical physicists expected as much. On the morning of ...

Dark energy is one of those cosmological features that we are still learning about. While we can't see it directly, we can most famously observe its effects on the universe—primarily how it is causing ...

Our universe is shrouded in mystery, with about 70 percent of it consisting of dark energy. The exact nature of dark energy remains a puzzle that, once solved, could unlock profound insights into the ...

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S ...

“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 ...

In the late 1990s, two teams of astronomers were out to settle a score. Cosmologists had been at odds for over a decade in their quest to measure the total amount of matter and energy in the universe.

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 ...

The original version of this story appeared in Quanta Magazine. Physicists have deduced subtle hints that the mysterious “dark” energy that drives the universe to expand faster and faster may be ...

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 ...
