The Atacama Cosmology Telescope in Chile not only confirmed one of the greatest mysteries in the universe—it also ruled out ...

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 ...

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 ...

The cosmological constant is presumably an enigmatic form of matter or energy that acts in opposition to gravity and is considered by many physicists to be equivalent to dark energy. Nobody really ...

Paul Sutter is an astrophysicist at The Ohio State University and the chief scientist at COSI Science Center. Sutter is also host of Ask a Spaceman, We Don't Planet and COSI Science Now. Sutter ...

The far distant fates of the Universe offer a number of possibilities, but if dark energy is truly a constant, as the data indicates, it will continue to follow the red curve, leading to the long-term ...

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 ...

Travel far enough in the universe and you could end up back where you began. Measurements from the Planck space observatory have shown that the universe might be shaped like a sphere rather than a ...

Researchers have used well-established cosmological observations to place tighter constraints on the quadratic model of the Generalized Uncertainty Principle, while discrediting the linear model. A ...

Thirteen million light years away, a handful of relatively small galaxies revolve in a disk around the larger elliptical galaxy Centaurus A. There’s nothing unusual about a collection of small ...
