A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard assumption is that the acceleration rate is itself ...

General Relativity continues to provide a robust framework for understanding the interplay between gravitational waves and the cosmological constant. Gravitational waves—ripples in the fabric of ...
