In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

Dark energy may be the most mysterious substance ever proposed, but many scientists are certain it exists. Why?

For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and ...

WASHINGTON (Reuters) - New data involving millions of galaxies and luminous galactic cores is providing fresh evidence that the enigmatic and invisible cosmic force called dark energy - responsible ...

Last spring, a team of nearly 1,000 cosmologists announced that dark energy — the enigmatic agent propelling the universe to swell in size at an ever-increasing rate — might be slackening. The ...

Cosmologists are finally beginning to sketch a coherent picture of the universe we cannot see, using exquisitely detailed maps of galaxies, ghostly light and the large scale structure of space itself.

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 ...

In the wake of bombshell findings that suggest dark energy might be weakening as the universe expands, physicists are considering replacing the standard cosmological model of the universe with exotic ...

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 ...

Is dark energy changing, or is it just more of the same? Last month, astronomers announced the startling finding that dark energy – which is thought to cause the accelerating expansion of the universe ...

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 ...
