How fast is the Universe expanding?
Professor Sherry Suyu presents an invited discourse on "The Hubble Tension" during the XXXI IAU General Assembly, which was held from 2-11 August 2022 in Busan, Korea. The lecture explained the contradictory values of the Hubble constant that have been measured by different methods, and outlined new methods of measuring it that could provide a solution.
