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 ...

For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and faster forever. Now a wave of new measurements suggests that this invisible ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

After 25 years of planning, six years of data collection, and six more years of analysis, scientists have published a portion of the final results of the Dark Energy Survey (DES) - the largest, most ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests. "Remarkable" findings published today in ...

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

The expansion rate of the universe may be slowing down, rather than accelerating at an ever-growing rate, a potentially groundbreaking new study has hinted. The suggestion challenges both the 2011 ...
