Is the universe’s expansion the same everywhere? New research suggests it’s not—which could have huge implications for our understanding of the cosmos. Scientists led by Konstantinos Migkas at the ...

“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 ...

The search for the universe’s center starts with a simple intuition: if everything exploded outward in the Big Bang, there must be a point it all came from. Modern cosmology turns that intuition ...

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 ...

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 ...

Those looking forward to a day when science's Grand Unifying Theory of Everything could be worn on a t-shirt may have to wait a little longer as astrophysicists continue to find hints that one of the ...

No matter where we look, the same rules apply everywhere in space: countless calculations of astrophysics are based on this basic principle. A recent study, however, has thrown this principle into ...

IT is often assumed that quasars are partaking in the general expansion of the substratum of an isotropic universe. This hypothesis requires that those quasars possessing any particular observational ...

Puzzling anisotropies in the cosmic microwave background radiation across the sky are leading some researchers to contemplate cosmology in an asymmetric universe. At the same time there are puzzling ...
