How did the data collected by the James Webb Space Telescope (JWST) affect the Hubble Tension?
Answer
It confirmed the high expansion rate, reinforcing the discrepancy with early universe predictions.
The JWST provided exceptionally sharp measurements, confirming the higher local expansion rate calculated from standard candles, which limits the possibility that the local measurements are simply riddled with unaccounted-for errors.
