Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

A scientific overview of a speculative cosmology idea and what current physics says about black holes, spacetime, and the structure of our universe.

A recent study published in The Astrophysical Journal Letters has provided the most precise distance to the Coma Cluster of galaxies yet — and also has deepened a crisis in cosmology. The problem is ...

Astronomers and cosmologists aren’t known for being incredible at adjectives. Take the Very Large Telescope, or the European Extremely Large Telescope, or even the big bang. But they weren’t wrong ...

Three papers published in JCAP presenting the sixth and final data release of the Atacama Cosmology Telescope offer a new map of the “infant” Universe, confirm the “Hubble tension,” and rule out a set ...

Let's rewind the clock back…oh, I don't know, let's say a hundred years. It was 1917, and Einstein had just developed his general theory of relativity. It was a masterpiece, giving us our modern-day ...

The expansion rate of the universe may be slowing down, rather than accelerating at an ever-growing rate, a potentially groundbreaking new study has hinted. The suggestion challenges both the 2011 ...

A scientist proposes a new law of physics suggesting the universe may be a digital simulation, linking physics, biology, and ...

There are a lot of (Python) cosmology libraries out there, from big projects -- including Astropy, CLASS, and CAMB-- down to small personal scripts. These libraries perform many of the same tasks, but ...

Our corner of the universe looks tidy at first glance. But pull back, and patterns begin to surface that stretch across billions of light-years. New mapping work hints that our own galaxy belongs to a ...
