There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on ...

What if the Universe were not symmetrical? This idea, which goes against what scientists have long believed, emerges from new studies on large cosmic structures. Instead of being uniform in ...

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...
