How do we measure the expansion of the universe?

In this conversation, Wendy Freedman discusses the Hubble constant, standard candles, redshift, and the ongoing effort to determine the age, size, and evolution of the universe. Exploring Cepheid variables, supernovae, cosmic expansion, and the tension between competing cosmological measurements, Freedman explains how increasingly precise observations are reshaping modern cosmology.

Wendy Freedman is an astronomer known for her measurements of the Hubble constant and for her leadership of the Carnegie Observatories in Pasadena, California, and Las Campanas, Chile.
