Astronomers haven’t thrown out the cosmological principle just yet, but they are gathering clues about its potential weaknesses. One approach involves looking for structures so large they ...

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 ...

The cosmological principle is the foundation of modern cosmology and has been confirmed many times by observations and computer models. It states that the universe looks the same from every location ...

“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 ...

The cosmological principle is useful for simplifying the universe, and astronomers use it to do everything from calculate the effect of dark matter on galaxy clusters to infer how common ...

In the paper, author considers a new method for constructing the quasi-equilibrium thermodynamics of a system of ...

Is it possible to understand the Universe without understanding the largest structures that reside in it? In principle, not ...

But, the Cosmological Principle may not be safe yet. Sure, it's 1-0 up at half-time, but the referee hasn't blown the whistle on full-time just yet.
