What Shall We Do with the Hubble Tension?

Explore the ongoing cosmological puzzle known as the Hubble tension in this 16-minute conference talk by Julien Lesgourgues from the Galileo Galilei Institute. Delve into the significant discrepancy between different measurements of the Hubble constant, which represents the current rate of expansion of the universe, and examine the various approaches scientists are taking to resolve this fundamental issue in modern cosmology. Learn about the competing measurement methods, the statistical significance of the tension, and the potential implications for our understanding of the universe's evolution and the standard model of cosmology.
