The big-idea explorers at Aperture decode dark energy and its mysterious role in stretching the universe beyond imagination.

For a quarter century, cosmology has leaned on one framework to explain how the universe expands. Known as the ΛCDM model, it assumes about 70 percent of the cosmos is filled with an unseen force ...

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 ...

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 ...

Ask most astronomers, and they’ll tell you that dark matter and dark energy make up more than 95 percent of the universe and that they are the explanations for many of the large-scale phenomena we ...

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 ...

The Dark Energy Survey collaboration is releasing results that, for the first time, combine all of the data from an intensive six-year mapping of galaxies in the universe. The new analysis, of ...

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...
