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 ...

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

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 ...

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 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 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 ...

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 ...

According to physics, the universe and everything in it can be explained by just a handful of equations. They’re difficult equations, all right, but their simplest feature is also the most mysterious ...
