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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. DESI has made the largest 3D map of our universe. The Earth is at the central vertex, and every ...

Robert Nichol is a member of the Dark Energy Survey collaboration. Dark energy is estimated to make up nearly 70% of the observable universe, yet we still don’t understand what it is. While its nature ...

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 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 ...

The theoretical framework underlying gravitational waves may have to be revamped to account for dark energy and the acceleration of the expansion of the universe. That’s the conclusion of researchers ...

Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in ...

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 ...

There may be fundamental flaws with our understanding of the universe. The problem came to light as scientists tried to calculate and measure a value called the Hubble Constant, which represents how ...

Licia Verde receives funding from the AEI (Spanish State Research Agency) project number PID2022-141125NB-I00, and has previously received funding from the European Research Council. Licia Verde is a ...
