Using the Coma cluster, over 1,000 galaxies 320 million light-years away, researchers refined distance measures.

By studying Type Ia supernovae, Scolnic’s team confirmed the Coma cluster's distance at 321 million light-years.

Calculations show space expanding at 76.5 km/s/megaparsec locally, contradicting ancient light measurements.

Local expansion rates clash with data from ancient light, which suggests a slower rate of 67.4 km/s/megaparsec.

The mismatch hints at either errors in our models or entirely new physics governing the cosmos.

Data from the Dark Energy Spectroscopic Instrument bridged measurement gaps, but mysteries remain.
As Scolnic notes, surprises in cosmology persist, hinting at discoveries that may reshape our understanding.
