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 accelerated expansion of the present universe, believed to be driven by a mysterious dark energy, is one of the greatest puzzles in our understanding of the cosmos. The standard model of cosmology ...
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 ...
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 ...
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 ...
"The cosmic dipole anomaly has thus established itself as a major challenge to the standard cosmological model, even if the ...
The expansion of the universe was not accelerating but was rather slowing down and at a rate much faster than expected, a new ...
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 ...
For over a century, scientists have wondered what is counteracting the force of gravity in the universe. The universe is vast, almost beyond comprehension. It has an estimated diameter of 93 billion ...
