85. Reframing the Hubble Tension Through the Sound Horizon

Helena García Escudero (Univesity of Southern California)

Talk at conference (week 3)

One of the most striking open problems in modern cosmology is the Hubble tension: the persistent disagreement between measurements of the present-day expansion rate of the Universe obtained from local observations and the lower values inferred from cosmic microwave background data within the standard ΛCDM framework. This mismatch has motivated extensive scrutiny of both late-time measurements...
