Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians ...

Astronomers have developed a new way to test one of the central assumptions of modern cosmology — that the universe behaves uniformly on the largest scales. When applying the method to real ...

Contemporary cosmology rests on a framework that describes the evolution and large-scale structure of the Universe through solutions of Einstein’s field equations. The standard paradigm, known as the ...

New telescopes are challenging the idea that the cosmic web fades into a uniform, directionless distribution. It may be ...

Sulfur is one of the most abundant elements in the universe. If you peer into a diffuse interstellar cloud, you find loads of it—about the amount expected based on fusion patterns in the stars it was ...

If you imagine the story of the universe as a film endlessly in post-production, cosmologists would be its obsessive editors, constantly tweaking the narrative. The version they are working with is an ...
