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.

New measurements show that the expansion rate of the universe is faster than can be explained by our current understanding of physics.

In a nutshell Astronomers studying the nearby Coma galaxy cluster have found new evidence that the universe is expanding about 9% faster than predicted by our current physics models – a discrepancy known as the Hubble tension.
