The James Webb Space Telescope (JWST) has calculated the expansion rate of the universe. The results have confirmed the biggest crisis in cosmology, the Hubble Tension. This means that the universe is expanding at a rate faster than what our best cosmological models predict, and no one knows why. The resolution of the Hubble Tension is important as it highlights a significant flaw in our understanding of the cosmos.
