Under the right conditions, this collapse doesn’t end in a singularity — instead, it bounces and begins expanding again,” said University of Portsmouth professor Enrique Gaztañaga in a statement that ...

Is the universe really uniform? A recent study published in the Journal of Cosmology and Astroparticle Physics (JCAP) explores this fundamental question using an innovative technique based on the ...

This principle assumes the Universe is homogeneous and isotropic on large scales. According to this principle, no structure should exceed 1.2 billion light-years, a limit imposed by the Universe's age ...

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 ...

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 humility ...

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.

'But whether you support or reject the cosmological principle, it's a difficult problem. Unlike laboratory tests that can be repeated over and over again, there is only one universe.' ...
