A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences ...

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 ...

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 ...

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 ...

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 ...

A cyclic universe, which bounces through a series of big bangs and “big crunches”, could solve the puzzle of our cosmological constant, physicists suggest. The cosmological constant represents the ...

There's always a touch of melancholy when a chapter that has absorbed years of work comes to an end. In the case of the ...

Little is known about what dark matter and dark energy, the dominant components of the universe, really are, but the standard model of Big Bang cosmology, known as ΛCDM, incorporates how they ...
