41 - The Hubble Tension: The Biggest Fight in Astronomy (ft. Wendy Freedman)

Why This Universe?

When different groups of astronomers measure the expansion rate of space, they get different answers. Who's right? Or are they both right, and new physics is afoot?Support the show

The Expanding Universe with Wendy Freedman

Big Brains

Wendy Freedman spent part of her career measuring the age of the universe. Now she’s working on a project that may very well give scientists a chance to glimpse into its birth.   Freedman, the John & Marion Sullivan University Professor of Astronomy & Astrophysics, works in the field of observational cosmology, measuring the expansion rate of the universe. In 2001, she and a team of scientists found that the universe is around 13.7 billion years old—far more precise than the previous estimate in the 10- to 20-billion-year-old range. Freedman was the founding leader from 2003 until 2015 of an international consortium of researchers and universities (including UChicago) to build the world’s largest telescope high in the mountains of Chile. The Giant Magellan Telescope will be as tall as the Statue of Liberty when complete, and ten times more powerful than the Hubble Space Telescope—with the ability to look back at the dawn of the cosmos. On this episode of Big Brains, Freedman discusses her research on measuring the age of the universe, her leadership of the Giant Magellan Telescope and the search for life outside our solar system.    Subscribe to Big Brains on Apple Podcasts, Stitcher, and Google Play, and learn more at news.uchicago.edu

Episode 86: When the Universe Began, with Wendy Freedman

The Star Spot

Feature Guest: Wendy Freedman A long long time ago in every place at once, all of this began. But when exactly did the universe begin? And how quickly did it expand into the structure we see around us? Those numbers are more difficult to nail down than we had thought, yet more critical to our understanding of the nature of the cosmos, of dark matter and dark energy, than we could have ever imagined. Today we're joined at The Star Spot by cosmologist Wendy Freedman who recently stepped down after 12 years heading up the development of the Giant Magellan Telescope. Current in Space Anuj wonders if magnetic worm holes will one day transport us to the far reaches of space. And with Pluto data analysis just getting underway, Tony provides the new targets for the New Horizons spacecraft. About Our Guest Wendy Freedman is Professor of Astronomy and Astrophysics at the University of Chicago. Among the world’s most influential astronomers, Freedman served as co-leader of the Hubble Space Telescope Key Project and is former director of the Carnegie Observatories in Pasadena, California. She served 12 years as chair of the Board of Directors for the Giant Magellan Telescope (GMT) Project, an optical telescope with a primary mirror 80 feet in diameter scheduled to begin operations in 2021. Freedman is a member of the National Academy of Sciences and the American Philosophical Society. She is a recipient of the 2009 Gruber Prize for Cosmology.
