Cosmology faces Hubble tension discrepancy in expansion rate predictions and observations.
Cosmology is facing critical challenges as recent observations challenge the standard model of the universe, which comprises 68.3% dark energy and 26.8% dark matter. A key issue is the "Hubble tension," a discrepancy between measured and predicted expansion rates. Despite expectations from the James Webb Space Telescope to clarify these issues, inconsistencies remain. Future data may either validate the model or indicate the need for new physics in understanding the universe.
