At the end of the interview, Trodden looks to the future and offers ideas on how physicists may ultimately come to understand dark energy and dark matter.

Interview with Gabriela Gonzalez, Louisiana State University Boyd Professor in the Department of Physics and Astronomy. Gonzalez explains how the pandemic has slowed down data analysis for LIGO, and she recounts her childhood in Cordoba, Argentina. She describes her early interests in science and her physics education as an undergraduate in Cordoba. Gonzalez explains the circumstances that led to her graduate studies at Syracuse University where she studied relativity under the direction of Peter Saulson, and where she first became involved with LIGO. She discusses her postdoctoral appointment at MIT to work in Rai Weiss’s group, and she explains LIGO’s dual goals of detecting gravitational waves and building precision instruments toward that end. Gonzalez explains her decision to join the faculty at Penn State and she describes the site selection that led to the detection facility in Livingston, Louisiana. She describes the necessary redundancy of the LIGO detectors at Livingston and Hanford, Washington, and the importance of “locking” the mirrors on the detectors. Gonzalez describes the overall scene at LIGO in the months up to the detection and the theoretical guidance that improved the likelihood of success. She describes the intensive communication and data analysis to confirm the detection prior to the announcement, and she explains how she felt honored as part of the overall Nobel Prize award and subsequent celebration. Gonzalez describes LIGO’s work in the current post-detection period, and her own focus on diagnostics of the data, and she explains why this work, and the constant concern in missing something important, can be stressful. At the end of the interview, Gonzalez surveys what mysteries LIGO can, and cannot, solve, and she conveys optimism for LIGO’s long-term prospects to continue to push fundamental discovery.

Interview with Lee Smolin, Founding and Senior Faculty Member at the Perimeter Institute with faculty appointments at the University of Toronto and the University of Waterloo. Smolin narrates the origins of the Perimeter Institute and he describes his unorthodox views on what exactly cosmology is. He describes loop quantum gravity and the notion of a “theory of everything” and why he has much love for string theory despite perceptions of the opposite. Smolin explains the utility and trappings of the Standard Model and he searches for deeper meaning in the origins and societal impact of the pandemic. He recounts his childhood in Cincinnati and his early appreciation for physics and the circumstances that led to his undergraduate education at Hampshire. Smolin explains his attraction in working with Sidney Coleman at Harvard, and why he saw a grand plan in his desire to learn quantum field theory. He describes meeting Abhay Ashtekar and his postdoctoral work at UC Santa Barbara and then at the Institute for Advanced Study. Smolin describes his formative relationship with Chandrasekhar at Chicago, his first faculty appointment at Yale, and his tenure at Syracuse where he found a strong group in relativity and quantum gravity. He explains his reasons for transferring to Penn State and his involvement in loop quantum gravity achieving a mature state amid a rapidly expanding “relativity community” throughout academic physics. He describes his time at Imperial College, where he developed a quantum gravity center with Chris Isham and he historicizes the technical developments that connected his theoretical work with observation. Smolin describes his book "The Life of the Cosmos" and his foray into thinking about biology and why he identifies as a self-conscious Leibnizian who tries to connect cosmology with the concept of a god and the centrality of astrobiology to these issues. At the end of the interview, Smolin explains why he continually returns to quantum gravity, and he conveys his interest in keeping philosophy at the forefront of his research agenda.

Abhay Ashtekar, Evan Hugh Professor of Physics and Director of the Institute for Gravitation and the Cosmos at Penn State, is interviewed by David Zierler. Ashtekar recounts his childhood in the Indian state of Maharashtra, and discusses his early fascination with physics and the universe. He describes his undergraduate interests in general relativity and the opportunities that led to his enrollment at the University of Texas to join the Center for Relativity. Ashtekar discusses the culture shock when he arrived in Austin and Bob Geroch’s mentorship in quantum gravity, and his decision to follow Geroch to Chicago. He describes his interactions with Chandrasekar and his graduate research on quantum field theory in curved space-times and the asymptotic nature of space-time. Ashtekar discusses his postdoctoral appointment at Oxford to work with Roger Penrose, and he explains the moral origins of his commitment to making his field visible and therefore richer in opportunity for junior scholars. He explains his reasons to return to Chicago for a second postdoc, his decision to join the faculty at Syracuse, and a formative visiting appointment he had in Paris. Ashtekar describes the attraction in joining the faculty at Penn State, and his increasing focus on loop quantum gravity and the intellectual origins of the Ashtekar variable. He explains these developments as part of the broader effort to merge quantum mechanics and general relativity and the implications this will have on our understanding of the Standard Model. Ashtekar surveys the field of loop quantum cosmology and its relation to both inflation and string theory, and he conveys the enjoyment he felt with the detection of gravitational waves. At the end of the interview, Ashtekar explains why he does not like the phrase “theory of everything,” he reflects on the lessons he has learned from the luminaries who have mentored him, and he explains why the field still does not fully understand quantum mechanics.
