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 ...

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 ...

One of the great scientific revolutions began with Copernicus, who opined that we occupied no special place in the Universe. As our view of the Universe expanded, we developed the cosmological ...

“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 ...

Feb 11, 2025: Does the universe behave the same way everywhere? Gravitational lenses could help us find out (Nanowerk News) “The cosmological principle is like an ultimate kind of statement of ...

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.

The Cosmological Principle sets an upper limit of 1.2 billion light-years on the size of any structures – a limit that the Big Ring blatantly disregards. To continue the analogy, ...

But according to the cosmological principle, the universe should be roughly homogeneous on large scales. The commonly accepted upper limit for such structures is about 370 megaparsecs (roughly 1.2 ...

The Cosmological Principle questions whether the universe is homogeneous or inhomogeneous. A stock photo shows a sky full of galaxies and stars. The Big Ring on the Sky was discovered by PhD ...
