Wendy Freedman, the former director of the Carnegie Observatories and now distinguished professor at University of Chicago, has been a leading figure in observational cosmology and astronomy for over 30 years. I have known her as a friend and colleague, and have learned much from her over the years, and was very excited to be able to snag her amidst her busy schedule to record a podcast a week or two before the release of a new blockbuster result her team had produced. I am very happy that Critical Mass listeners will be among the first to get the detailed lowdown on the likely resolution of a problem that has been plaguing cosmology for the past decade. In the 1990's Wendy led a major international team of astronomers in carrying the Hubble Space Telescope Key Project. The Hubble Space Telescope (HST) was named in part because of this project, to establish the distance scale of the universe and measure its current expansion rate, a quantity not coincidentally called the Hubble Constant, first measured by Edwin Hubble in 1929. Since that time, different groups have measured this most important single observable in our universe and gotten widely different values. In the 1980's and early 90's two different groups got values that differed by a factor of 2, even though each claimed errors of less than 10%. In 2001, Freedman's team published their result, truly accurate to 10%, and the value, perhaps not surprisingly, fell right in the middle between the previous two discrepant values. All was good, until inferences based on the Cosmic Microwave Background, the most precise observable in modern cosmology suggested that measurements at a time when the universe was 300,000 years old, when extrapolated forward using the best current theory of cosmology today, would give a value that different from the HST value. The difference was statistically significant, and as time proceeded, and error bars got smaller, the discrepancy between the HST (and then the James Web Space Telescope (JWST)) measurement, and the CMB measurement got more significant. Was our current model of cosmology simply wrong?Such was the claim in various places over the past few years. Most recently, Wendy led a team to measure cosmic distances in 3 different ways using JWST, and as she describes in our discussion, it looks like the problem may now be solved, although not without leaving other mysteries.We talked about a lot more than this though. Wendy's background, what got her into astronomy, her experiences throughout her career, and her leadership in a new project building the Giant Magellan Telescope, what will be the largest telescope in the world in Chile. The discussion was as fun as it was exciting. Wendy is a wonderful popular expositor, and as always, I really enjoyed talking to her. Tune in to hear, for the first time, about the newest and most important recent result in cosmology from one of my favorite colleagues and a world class scientist.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers. Your subscriptions support the non-profit Origins Project Foundation, which produces the podcast. The audio version is available free on the Critical Mass site and on all podcast sites, and the video version will also be available on the Origins Project YouTube.

In the first half, cosmologist and professor of physics Brian Keating discussed how the universe may have come into existence and various astronomy-related topics. Keating is the inventor of the BICEP (Background Imaging of Cosmic Extragalactic Polarization). This technology glimpses the earliest fossil relics of our universe, which come in the form of gravitational waves. Data has shown that the universe is expanding at an increasing rate, every single day, every single second, and every single year, he pointed out. "And because of that...that means yesterday the universe is slightly smaller. And if you go back enough yesterdays, you come to a time in which all those galaxies were in the same point. That point is sometimes called the Big Bang, the initial singularity which unleashed into the universe all the structures that we see now," Keating explained.In 1965, the microwave and radio imprint of the oldest light in the universe was discovered-- it occurred 380,000 years after the Big Bang, he detailed, adding that scientists are still studying this initial glow. The new Giant Magellan Telescope, which is being built in Chile, will examine this first glow. Speaking about the concept of a multiverse, he noted that it's a "consequence" of various cutting-edge physics theories like string theory, which suggests that as matter is divided into smaller and smaller particles, it allows for infinite manifestations. Further, the notion of an expanding or inflating universe indicates the existence of a multiverse, he added. Keating also touched on issues related to the competitiveness surrounding the Nobel Prize, and actor Terrence Howard's controversial and viral claims about mathematics and technology.----------------In the latter half, spiritual catalyst, intuitive, and multi-dimensional channel Lori Spagna talked about developing intuition and aligning with one's soul agenda for personal growth and well-being. She described intuition as an inner knowing that develops over time, and may include various extrasensory abilities like clairvoyance. Living in accordance with intuition leads to self-trust, virtues, and a higher ideal, benefiting all, with no harm to anyone, Spagna outlined. We should listen to the inspiring voices in our head that can come from our higher self or "divine team," but beware of unhelpful voices (which might stem from a trickster or demon). If the latter happens, she suggested that individuals affirm sovereignty over their mental space, which requires tricksters to leave.She described her communicative work with what she calls the "Collective"-- a team of hundreds of angelic beings, ascended masters, Animal Kingdom members, and even the consciousness of Mother Earth. Within the Collective, she also interacts with the "Fleet," whom she said are interstellar, intergalactic beings. These beings are non-physical, "but they have the ability to traverse different frequency ranges or bandwidths." When connecting with them, she said she merges with them at their frequency of consciousness in order to bring their insights through. Spagna also discussed the unique abilities of animal companions to perceive and understand human emotions, as well as their role in providing emotional support. During the last hour, she gave readings to callers.

Welcome to the Big Glass Wars! That's right, just when you thought you'd heard it all, turns out there's hot competition among a few countries to stay on the cutting edge of optical astronomy, and to do that, you need a great big hunk of glass to gather light from distant galaxies and stellar systems. Enter the Carnegie Observatories and their partners on the Thirty Meter Telescope and the Giant Magellan Telescope. Both are currently under construction, and both are threatened by budget parsimony from the U.S. Congress. Dr. John Mulchaey, Director of the Carnegie Observatories, joins us to discuss what's happening, why it matters, and what you can do to help maintain U.S. leadership in astronomy, cosmology, and other STEM-related fields. Headlines: Boeing's Starliner launch to the ISS delayed again, this time due to a helium leak in the service module. The launch is now targeted for no earlier than May 21st. Blue Origin plans to conduct its first crewed suborbital flight since August 2022 on May 19th, carrying six passengers including the first Black astronaut candidate Ed Dwight. A massive sunspot caused spectacular auroras visible as far south as Alabama and turned skies purple and orange. More solar activity is expected as another large sunspot emerges. Main Topic: The Big Glass Wars with Dr. John Mulchaey Dr. Mulchaey provides an overview of the Carnegie Observatories, founded in 1904, and their historic telescopes at Mount Wilson that helped launch modern astronomy. He discusses the need for extremely large next-generation ground-based telescopes, the Giant Magellan Telescope (GMT) and Thirty Meter Telescope (TMT), to study earth-like exoplanets and the early universe. These ambitious segmented mirror telescopes will be 5-10 times larger than today's biggest telescopes and cost billions of dollars to construct. While substantial private funding has been raised, the projects need investment from the National Science Foundation (NSF) and the U.S. government to be completed. However, the NSF has proposed only partial funding. Dr. Mulchaey emphasizes the importance of the U.S. having both telescope projects to provide full-sky coverage, double the observation time, and maintain the nation's leadership in astronomy research or risk losing top talent to competing projects in Europe and China. He notes that delaying a decision on full funding is causing the estimated costs to escalate as the projects are forced to wait. Dr. Mulchaey argues passionately that inspiring the next generation of scientists and engineers by investing in these telescopes is critical for the country's future productivity and innovation.

Professor Chris Impey interviews Dr. Buddy Martin, Chief Polishing Scientist at the Steward Observatory Mirror Lab. Dr. Martin is the Project Scientist for Mirror Polishing at the Richard F. Caris Mirror Lab. He leads the development of fabrication and testing for large optics, including the 8.4 m segments of the Giant Magellan Telescope. Previous manufacturing achievements include the two 8.4 m primary mirrors of the Large Binocular Telescope, the 8.4 m combined primary and tertiary mirror for the Large Synoptic Survey Telescope, and thin deformable secondary mirrors for the LBT. Buddy has a Ph. D. in physics from Cambridge University and has been at Steward Observatory since 1986. He worked in radio astronomy before moving up to manufacturing optics.

Professor Chris Impey interviews Dr. Roger Angel, Director of the Steward Observatory Mirror Lab about the process of creating the larges telescope mirrors ever made. Over the past 25 years Professor Angel has been in the forefront of a technological renaissance in telescopes and large optics. The Mirror Lab has made the optics for several telescopes, including the two largest mirrors ever (8.4 m diameter) for the Large Binocular Telescope on Mt. Graham, Arizona and is now making 8.4 m mirrors for the Giant Magellan Telescope and the Large Synoptic Survey Telescope. Angel has also developed concepts for imaging and searching for primitive life on Earth-like planets orbiting nearby stars. He has explored ways to cool the Earth with a space sunshade, and is now working on concentrating photovoltaic systems for solar energy.

Making a mirror for a giant telescope requires a long-term commitment. Back in March, for example, GMT — the Giant Magellan Telescope — began work on the sixth of its mirrors. It'll take about three years to finish the job. GMT will use a total of seven mirrors. They'll work together to act as a single mirror about 80 feet in diameter — far larger than any current telescope. That will allow GMT to see stars and galaxies that are much fainter and farther, greatly expanding our view of the universe. Each mirror is cast in a circular furnace at the University of Arizona. About 20 tons of a special glass is heated to more than 2100 degrees. The furnace rotates, sculpting the molten glass to the proper shape. It takes about three months for the mirror to cool. Technicians then spend more than two years grinding and polishing it. The surface has to be smooth to within a millionth of an inch. Buddy Martin, who leads the process, described that level of accuracy during a March press conference. MARTIN: If the mirror were expanded to the size of North America, 3500 miles in diameter, then the average hill would be two-thirds of an inch tall and the average valley two-thirds of an inch deep. That's how smooth this mirror has to be for it to make the sharpest images that nature will allow. All the mirrors are scheduled to be sent to GMT's mountaintop site, in Chile, late in the decade.  Script by Damond Benningfield Support McDonald Observatory

Darren DePoy, Professor of Astronomy and Associate Dean for Research at Texas A&M University in College Station, talks about using one of Einstein's little-known and underappreciated method of microlensing to look for extrasolar planets around sunlike stars.  An expert on building telescope instrumentation, DePoy outlines the other methods of planet detection and a bit about the difficulties of funding huge astronomical projects such as the Giant Magellan Telescope.

During Episode 12 of Black in Science, I spoke with the world renowned physicist, Dr. Walter E Massey, who's currently working as Chairman of the Board for the construction of the Giant Magellan Telescope in Chile. Throughout the interview, Dr. Massey describes his long list of career achievements, including his previous appointment as the Director of the National Science Foundation (NSF) by President George H.W. Bush and his 12 year tenure as President of Morehouse College in Atlanta, Georgia. After describing his childhood while growing up in southern Mississippi during segregation, Walter recounts his time as an undergraduate student at Morehouse and the work he did at Washington University in St. Louis for his Ph.D in physics. Before closing, Dr. Massey shares the details of his newly released memoir detailing his time as Chairman of the Board at Bank of America and a few pearls of wisdom he picked up during his career. If you're interested in hearing more about Dr. Massey's story, feel free to purchase a copy of his memoir entitled In the Eye of the Storm: My Time as Chairman of Bank of America During the Country's Worst Financial Crisis on Amazon.

What Went Wrong With Jackson, Mississippi’s Water? Residents of Jackson, Mississippi have been dealing with a water crisis since a storm rolled through town on February 15th. The city’s water system was damaged, leaving thousands of residents without running water at home. People have relied on water distribution sites to get by, and even those who can still use their taps are on boil water notice. Impacted residents are largely low-income, and the limited access to water has raised worries about staying safe during the COVID-19 pandemic. Even before this fiasco, Jackson’s water system was in need of a change. Boil water advisories were common, and many of the city’s pipes date back to the 1950s. Water service is expected to be restored this week, but getting the taps running again will just be a Band-Aid: A true overhaul would require millions, if not billions of dollars. Mississippi Public Broadcasting reporter Kobee Vance joins guest host John Dankosky to discuss what’s happening in Jackson, and why its infrastructure was particularly vulnerable to this crisis.   Spinning Glass To See The Stars Last weekend, a giant furnace built under the east stands of the University of Arizona football stadium began to spin. That furnace contained some 20 tons of high-purity borosilicate glass, heated to 1,165 degrees C. As the glass melted, it flowed into gaps in a mold. The centrifugal force of the spinning furnace spread the material up the edges of the mold, forming the curved surface of a huge mirror, with a diameter of 8.4 meters. The piece is just one of seven sections that will eventually form the 25-meter primary mirror of the Giant Magellan Telescope in Chile. It’s not a fast process—it will take several months to cool, and then another two years to measure, grind, and polish. When that’s complete, the surface of the mirror segment will be accurate to within twenty-five nanometers. Steward Observatory mirror polishing program project scientist Buddy Martin says that when it’s complete, the Giant Magellan Telescope should be ten times sharper than the Hubble Space Telescope—if it was positioned in Washington, DC, it would be able to make out a softball in the hand of a pitcher in San Francisco. Martin talks with SciFri’s Charles Bergquist about the mirror production process, and the challenges of working with glass on massive scales. Watch a video and see photos of the process at scienefriday.com.   It’s Time To Rethink Shark Sex—With Females In Mind Sharks, rays, and skates—all fish in the subclass Elasmobranchii—are a beautifully diverse collection of animals. One big way they differ is in how they reproduce. They lay eggs, like traditional fish, and let them mature in a select corner of the ocean. Or, they might let the eggs hatch inside their bodies. But they can also give live birth to pups gestated like mammals: with an umbilical cord and a placenta in a uterus. It doesn’t end there. These fish, like many other members of the animal kingdom, have two uteruses. Females are capable of reproducing asexually, without help from a male. As genetic sequencing has advanced, researchers have been finding another curious pattern: Many litters of pups will have more than one father, a phenomenon known as multiple paternity. Evolutionary ecologists seeking to explain why sharks would use this strategy of multiple paternity have hypothesized it’s one of convenience for females. In species with aggressive and competitive mating practices, like many sharks and rays, it’s possible females find it saves them precious resources to acquiesce to multiple males. But what if there’s something in it for the female, and her likelihood of having successful, biologically fit offspring? That’s the question a team of researchers sought to answer in new research published in Molecular Ecology this month, where they asked what kinds of physiological mechanisms a female shark or ray might use to wield agency in her own reproduction. The researchers also write that a male-dominated field may be more likely to miss a female-driven reproductive strategy, and push for more study of female reproductive biology. John Dankosky talks to the lead author on the research, Georgia Aquarium shark biologist Kady Lyons, about the vast wonderland of reproductive strategies in this fish subclass—and what a history of male-centered research may have missed.   What Next For The Fully Vaccinated? In the U.S., vaccines have been rolling out since December. According to the Centers for Disease Control and Prevention, more than 95 million doses have been administered which equates to over 18% of the population. This week, the agency also put out guidelines for those who have been fully vaccinated. Sophie Bushwick of Scientific American fills us in on those guidelines and also talks about research on the effectiveness of mask mandates and a headless sea slug.

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

An in-depth conversation with Professor Wendy Freedman on the topic of space exploration with ground based telescopes. We discuss the history of space exploration using ground based telescopes, and try to imagine the future that what is next. Professor Wendy Freedman gives a detailed description of the features of the Giant Magellan Telescope, a ground based extremely large telescope under construction. We discuss the challenges involved in constructing the GMT and talk about the research opportunities that this extremely large telescope, once completed, will present. Professor Wendy Freedman is one of the world’s most influential astronomers. Freedman is a professor of Astronomy and Astrophysics at the University of Chicago. She was also the chair of the board of directors of the Giant Magellan Telescope project from its inception in 2003 to July 2015. More than a decade ago, Wendy Freedman led a team of 30 astronomers who carried out the Hubble Key Project to measure the expansion rate of the universe. Her research now focuses on measuring both the past and present expansion rates of the universe, and on characterizing the nature of dark energy – the mysterious force that causes the universe to accelerate its expansion. A Correction Note (Audio at 14:10 minutes): While discussing 60-inch telescope at Mount Wilson Observatory, we got the dates mixed up. The telescope was commissioned in 1908; the 'First Light' was on December 8, 1908. Astronomer Harlow Shapely used this telescope to make a number of observations about our galaxy the Milky Way. However it was not until 1917-18 that he concluded, based on his observations, that the Sun was not at the centre of our galaxy.

Outer space - does it allure and call out to you? Does it fascinate you to ponder how the universe and galaxies come into being? How do galaxies grow over time and change dramatically across different regions of outer space? How do they grow their stars, black holes, and dark matter? These are some of the questions that drive the research of this episode's guest, Dr. Shardha Jogee. She will share her early deep fascination with science, how she dared to dream big, and how it all culminated against all odds in her career as an astronomer, professor, and chair of the Department of Astronomy at the University of Texas at Austin. She will discuss some of her exciting research using NASA's Hubble, Spitzer, and Herschel Space Telescopes, McDonald Observatory, and the future Giant Magellan Telescope, and invite young minds to join the journey of scientific exploration. She will also share the excitement of advancing Texas Astronomy in her role as department chair.

Presented by Associate Professor Kim-Vy Tran on Friday 9 October 2015.Since Galileo's time, our ability to study the universe has been driven by our ability to collect light from distant objects. Due to tremendous technological advances in the last few decades, we can now study the most distant galaxies known in the universe. In addition to seeing fainter objects at higher resolution, we can also view the universe at many different wavelengths ranging from gamma rays to radio waves. I highlight the major advances that have been made with, e.g. the Keck telescopes and Hubble Space Telescope, and discuss why we need to continue pushing our limits by developing and building new observatories like the Giant Magellan Telescope.

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.

With today's technology, astronomers can see billions of years into the past, but they've never been able to see the first light emitted in the universe after the Big Bang. That could be about to change thanks to a new high-powered telescope being developed by the University of Chicago and ten partner organizations. The billion dollar Giant Magellan Telescope is one of the first in a new generation of extremely large, earth-based telescopes, which may spur a new era for astronomy. Wendy Freedman is the board chair for the Giant Magellan Telescope Organization, and a professor of astronomy and astrophysics at the U of C. She joins us with more.

Presented by Prof. Jeremy Mould on 7th May 2015.The skies of northern Chile are considered the best in the world for astronomy at visible through millimetre wavelengths. Most of the observatories are in the Norte Chico and Atacama regions. Cerro Paranal Observatory is the largest in the world. The Atacama Large Millimeter Array is an international astronomical facility composed of a group of up to 66 radio antennae working together 5000 meters above sea level in the hghlands (Llano de Chajnantor) of the Andes Mountain Range, 50 kms from San Pedro de Atacama. ALMA is the most global astronomical project. Under development is the LSST - Large Synoptic Survey Telescope. The project, which brings together 19 universities and laboratories is under construction on Cerro Pachon and will be able to view, weekly, the entire visible Universe using a digital camera of 3000 million pixels. Cerro Armazones, 3,060 meters in height, situated in the Atacama desert some 130 km south of Antofagasta, Chile, is the site chosen for the largest telescope in the world -known as European Extremely Large Telescope (E-ELT). Las Campanas observatory is operated by Carnegie Institution of Washington, and its location is 2,500 meters above sea level. It will host the Giant Magellan Telescope. Australian astronomers are participating in its construction.

The international consortium of the Giant Magellan Telescope (GMT) project has passed two major reviews and is positioned to enter the construction phase. When completed, the 25-meter GMT will have more than six times the collecting area of the largest telescopes today and ten times the resolution of the Hubble Space Telescope.

On Friday, March 23, the first blast (Big Bang Event) occurred at Las Campanas Peak in Chile, at high noon US Eastern Daylight Time. It marked the beginning of mountain leveling and site preparation for the Giant Magellan Telescope.
