JWST Unveils Universe's Expansion Rate, Solving Physics' Mystery

The James Webb Space Telescope (JWST) has confirmed previous measurements of the universe's rate of expansion, known as the Hubble Tension. However, these measurements contradict predictions based on the cosmic microwave background, leaving astronomers with a significant problem to solve. The discrepancy may indicate the presence of exotic dark energy, dark matter, a revision to our understanding of gravity, or the existence of a unique particle or field. The study has been accepted by The Astrophysical Journal.
