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 widely accepted theory at the present moment ...

"The cosmic dipole anomaly has thus established itself as a major challenge to the standard cosmological model, even if the ...

DESI has made the largest 3D map of our universe. The Earth is at the central vertex, and every dot is a galaxy. DESI collaboration and KPNO/NOIRLab/NSF/AURA/R ...

The universe is expanding at an accelerated rate and our current best theories to explain this is a mysterious form of energy called "dark energy" that by its very existence is pushing the universe to ...

As I finished my PhD in 1992, the universe was full of mystery – we didn’t even know exactly what it is made of. One could argue that cosmologists had made little progress in our understanding of ...

The standard cosmological model known as Lambda-CDM (ΛCDM) proposes that dark energy is a constant force in the universe. However, an early “hint” in a new detailed map from the Dark Energy ...

Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two recent articles highlight its role in modern physics and cosmology. Before becoming widely ...

Here’s what you’ll learn when you read this story: A new paper adjusts an equation that defines our universe in response to recent new data. The cosmological constant, which describes how our universe ...

For a quarter century, cosmologists have treated dark energy as a fixed, featureless pressure that steadily drives galaxies ...

In every bit of nothing, there is something. If you zoom in on empty space and take out all the planets and stars and galaxies, you might expect a pure vacuum, but you’d be wrong. In­stead you would ...

Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two papers recently published in EPJ H highlight its role in modern physics and cosmology. Although ...
