The search for the universe’s center starts with a simple intuition: if everything exploded outward in the Big Bang, there must be a point it all came from. Modern cosmology turns that intuition ...

The expansion of the universe may be slowing down rather than accelerating, according to a new study that challenges the Nobel Prize-winning theory of dark energy. “If confirmed, this would have ...

The term “expanding universe” is often misunderstood, even by people familiar with astronomy. This explanation breaks down what actually expands and what does not, using modern cosmology rather than ...
