After five years of staring at the night sky from a mountaintop in Arizona, the most ambitious galaxy-mapping experiment ever ...

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 ...

Although some compelling evidence exists to support the idea that a repulsive force similar to dark energy exists, it has yet to be directly observed or measured. To circumvent this uncomfortable ...

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 ...

Our universe has been expanding ever since it was born in the Big Bang. For decades, most cosmologists believed the universe’s expansion was slowing. Gravity, pulling on all matter, would eventually ...

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 ...

"Understanding dark energy and its impact on our Universe is one of the biggest challenges in cosmology," said Dr. Daniele Sorini, lead researcher. "Surprisingly, we found that even significantly ...

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 ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our ...
