It’s a nerve-wracking time for cosmologists—is everything they thought they knew about to come crashing down? This is the first of two episodes that explore a looming crisis in cosmology.

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.

If this gigantic cosmic void does exist, it could help astronomers solve one of the greatest mysteries of our universe.

Out of its past troubles, the model may emerge not only vindicated, but also strengthened, and cosmology will be a science that is both precise and accurate.
