Astronomers have found that the universe appears to be expanding at different speeds depending on where they look.

Some of the measurements confirm our best current understanding of the universe, while others threaten to break it.

A new study suggests the tension may arise from measurement error and not exist after all.

JWST will make even more measurements of Cepheid stars in the next two years .

Freedman expects this work to be completed in two years ; whether additional measurements are sufficient will resolve the problem.

"We're in the midst of this, and there's more to come," Freedman said.
