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 ...

A new study claims to show evidence of gamma-ray emissions that closely resemble those expected from two weakly interacting massive particles, or WIMPs, colliding and annihilating.

Dark energy, a mysterious force that scientists believe is behind the accelerated expansion of the universe, is weakening — which could result in the universe over the course of billions of years ...

A new study using the Dark Energy Survey (DES) final datasets suggests potential inconsistencies in the standard cosmological model, known as ΛCDM. If confirmed, these findings could fundamentally ...

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 ...

Hints that dark matter might be destroying itself have flickered through astronomical data for more than a decade, but a new ...

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 ...

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 ...

Rossana Ruggeri is the recipient of an Australian Research Council (ARC) Discovery Early Career Researcher Award (DECRA), which supports her independent research project titled "Probing Dark Energy ...

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 ...

An international group of more than 900 researchers studying the expansion of the universe presented their findings on Wednesday during the American Physical Society’s Global Physics Summit in Anaheim ...
