Cosmology is a branch of physics that grapples with the big questions on the nature of our universe, including where it came from and what will happen to it next. At Live Science, we make this complex and sometimes mind-bending science accessible, explaining everything from the speed of light to the multiverse theory, and describing all of the wild theories about the universe.
Our expert writers and editors also break down new developments in the field, whether it’s how “Dark sirens” could solve one of the greatest mysteries in cosmology or why the launch of the Euclid space telescope is groundbreaking, with the latest cosmology news, features and articles.
