In the basement of Kirchhoff-Institut für Physik in Germany, researchers have been simulating the Universe as it might have existed shortly after the Big Bang. They have created a tabletop quantum ...

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

“The cosmological principle is like an ultimate kind of statement of humility,” explains James Adam, astrophysicist at the University of the Western Cape, Cape Town, South Africa, and lead author of ...

A study published in the Journal of Cosmology and Astroparticle Physics (JCAP) presents a methodology to test the assumption of cosmic homogeneity and isotropy, known as the Cosmological Principle, by ...

CC0 Usage Conditions ApplyClick for more information. One of the fundamental ideas of cosmology is that everything looks the same in all directions if you look over large enough distances. A new study ...

“The Copernican principle is a cornerstone of most of astronomy, it is assumed without question, and plays an important role ...

The Einstein–Gauss–Bonnet framework extends Einstein’s theory of General Relativity by including a higher-order curvature term that gains dynamical relevance in dimensions beyond four. This approach ...

Astronomers have uncovered two extraordinary cosmic structures that are challenging long-held assumptions about the nature of ...

New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against scientists' models of cosmic evolution.
