Summary

Discrepancies between different measurements of the Hubble constant have caused a major crisis in cosmology. Our guest today, the incredible Wendy Freedman, is at the forefront of efforts to resolve this tension. Known for her pioneering work on the Hubble Key Project and her important contributions to the measurement of the Hubble constant, Wendy is now using the James Webb Space Telescope to bring clarity to this debate. With decades of experience and a deep understanding of the complexity of cosmic measurements, there is no one better to shed light on this issue. So, can the James Webb Space Telescope help solve one of the biggest puzzles in cosmology? Tune in to this episode of Into the Impossible to find out!— Key Takeaways: 00:00 Intro 01:18 The role of JWST in solving the Hubble tension 04:01 Comparing different distance indicators 20:45 Standard sirens 34:05 Accurate cosmology vs. precision cosmology 36:35 Vera C.

0:00.0	Did the James Webb Space Telescope just solve the biggest mystery in cosmology?
0:04.4	The discrepancy between different measurements of the Hubble constant has been causing a lot of
0:09.2	Ajita in the astronomical community for the past few decades.
0:13.2	But Wendy Friedman, a renowned astronomer and professor at the University of Chicago,
0:17.8	is at the forefront of efforts to alleviate and solve this cosmic conundrum, known for her pioneering work on the Hubble
0:26.4	key project, the very reason the Hubble Space Telescope was launched in part, and her significant
0:31.2	contributions to measuring the Hubble constant and properties of stars throughout the universe.
0:36.4	Friedman is now leveraging the cutting-edge capabilities of the Web Space Telescope to tackle the Hubble tension head-on,
0:42.2	with decades of experience and a deep
0:44.2	understanding of the intricacies of cosmology of measurements of accuracy and
0:48.6	precision there's simply no one better to shed light if you will on this issue so join us we take a deep
0:54.9	dive and perhaps resolve the tension the frustration and the anxiety plaguing
1:00.0	astronomy today courtesy of the brilliant Wendy Friedman.
1:03.4	Let's go.
1:04.4	Any sufficiently advanced technology is indistinguishable from magic.
1:16.5	Open the pod bay doors now.
1:18.5	Wendy Friedman, thank you so much for coming back on the podcast, your second time on the
1:22.3	podcast. Glad to do so. Yeah, thanks for hosting. much you're coming back on the podcast your second time on the podcast
1:23.4	glad to do so yeah thanks for hosting me and your beautiful office here at the
1:26.9	University of Chicago it's so he's a pleasure to come here I get to experience
1:31.0	humidity whenever I come from Southern California where you used to live for many years.
1:35.8	I do.
