The End of Everything with Dr. Katie Mack Part 2

How did the universe evolve, and more importantly, how might it end? To find out, Dr. Charles Liu and co-host Allen Liu welcome theoretical cosmologist and astrophysicist, Dr. Katie Mack, author of the recently published book, “The End of Everything (Astrophysically Speaking).” In Part 2, we look at dark matter, Gravitational Memory Effect, and more. (You can listen to Part 1 here.) We dive right in with a question from David: “I was wondering if any physicists have looked into the idea that the “empty” space in an atom is actually “filled” with dark matter. What experiments could be done to prove or disprove this hypothesis?” In order to answer David, first Katie explains the science supporting the idea that dark matter exists, including gravitational lensing and other evidence. The fact that there are indications of dark matter in areas where there is sparse regular matter suggests that dark matter is an entirely different kind of particle. Katie describes many of the ways that that dark matter is unrelated to the empty space in atoms, including the fact that dark matter has no real interaction with atoms at all. Chuck asks whether the amount of dark matter still holds the key to how the universe evolves as he was taught or have new understandings made it entirely irrelevant? Katie explains that dark energy has replaced dark matter in importance, and that's what's making the universe expand faster. But we really don't know what it is, or what it's doing, or even if it will remain constant. Our next question comes from Aileen Balderas: “I recently read about something called the Gravitational Memory Effect. This talks about how space remembers certain things. Gravitational wave signals have the power to make it so that the universe remembers what happens to it. How can scientists say that the universe is able to remember things?” Katie unpacks this fascinating phenomenon which she only learned about five years ago. It turns out that, as Chuck puts it, “The universe has memory the way that memory foam has memory, not like the way elephants have memory.” Chuck asks Katie about flying planes, which she learned to do in late 2020 during the pandemic, after her book came out. Talk about a lockdown hobby! Katie shares why she loves flying so much, and what she gets out of it. And while she doesn't own her own plane, she has a share in a single engine airplane with 4 other people. Chuck also asks the inevitable question: Star Trek or Star Wars? Katie's answer: Star Trek! We end the show with Katie describing what she's doing at The Perimeter Institute, an independent research institute that's dedicated to stretch the boundaries of our understanding of physics in areas like cosmology, particle physics, quantum information and various areas of theoretical physics. Katie's been working with them to create some short videos. Check out Perimeter Institute for Theoretical Physics on YouTube to watch "Quantum Physics 101" and "Cosmology 101."

Salmaan Chettih, a postdoctoral researcher in neuroscience at Columbia University, investigated how chickadees encode their internal treasure maps. In his study in the journal Cell, he found the chickadee brains produce a unique pattern of activity — akin to a neural “barcode” — that marks the X on its mental treasure map. Italians don't just speak more with their hands, they speak differentlyResearchers comparing Swedish speakers with Italian speakers have found that the gestures they commonly use to accompany spoken language are quite different in kind. Lund University scientists Maria Graziano and Marianne Gullberg recorded the hand gestures study participants used when describing a children's cartoon to their friends. According to the results published in a Frontiers in Communication journal, Swedish speakers used gestures that concretely represented the subjects of their speech, while Italian speakers used abstract gestures more related to emphasis. What came first, the drumstick or the omelette?New archaeological work along the famous Silk Road trade route between Asia and Europe has added to the picture of how the chicken was brought from its southeast Asian homeland to the rest of Eurasia. An international team of researchers, including archaeobotanist Robert Spengler, analyzed tiny eggshell fragments from the soil of multiple sites in Central Asia. Their findings, published in Nature Communications, suggest that the motivation for domesticating the fowl was not the chicken, but their eggs. LED lighting is bright, efficient, and perhaps a problemThe global transition to LED lighting seems to be having some concerning impacts on the natural world and human health. These energy efficient artificial lights produce different spectra than older incandescent technology, or the natural light of the Sun that life on Earth evolved with over billions of years. LED lighting is brighter, bluer, and more widely used than incandescent lighting. Glen Jeffery, a professor of neuroscience from University College London, said that as a result, we may be paying the price with our health due to being oversaturated with blue light and starved of red and infrared light. In a new study in the Journal of Biophotonics, he found that exposing people to red and infrared light lowered their blood glucose levels by “charging up” our cells' energy production.Artificial light at night is also having “a profound impact” on our environment in how it affects plants and wildlife and the ecosystems they're in, according to Kevin Gaston, a professor of biodiversity and conservation at the University of Exeter. He said for nocturnal animals, the challenge they face from light pollution is the equivalent to humans losing daylight during the daytime. His review was published in the Annual Review of Environment and Resources.

Interest in the multiverse theory, suggesting that our universe is just one of many, has spiked since the movie Everything Everywhere All At Once was released. The film follows Evelyn Wang on her journey to connect with versions of herself in parallel universes to stop the destruction of the multiverse. The multiverse idea has long been an inspiration for science fiction writers. But does it have any basis in science? And if so, is it a concept we could ever test experimentally? Featuring Andrew Pontzen, professor of Cosmology at University College London, Katie Mack, Hawking chair in cosmology and science communication at the Perimeter Institute for Theoretical Physics, and Sabine Hossenfelder, research fellow of physics at the Frankfurt Institute for Advanced Studies.

Katie is a theoretical cosmologist who holds the Hawking Chair in Cosmology and Science Communication at Perimeter Institute. Her academic research investigates dark matter, vacuum decay and the epoch of reionisation. Katie is also a popular science communicator who participates in social media and regularly writes for Scientific American, Slate, Sky & Telescope, Time and Cosmos. She is the author of the book “The End of Everything (Astrophysically Speaking)” In Sentientist Conversations we talk about the two most important questions: “what's real?” & “who matters?” Sentientism is "evidence, reason & compassion for all sentient beings." The video of our conversation is here on YouTube. We discuss: 00:00 Welcome 01:58 Katie's Intro - #cosmology & #astrophysics - "The study of the universe from beginning to end from the smallest to the largest scales" - #darkmatter, the beginning of the universe & the end of the universe - Research & public engagement 03:33 What's Real? - Growing up going to church & youth group & #bible study - United Church of Christ... liberal & open-minded #socialjustice #lgbtq rights - Useful guidelines for life but "I never really understood how faith works... believing things without evidence" - Exploring different religious traditions e.g. #judaism "attending church on Sunday mornings and synagogue on Friday nights" - "I always wanted to believe something... there's a fundamental urge most humans have to connect with the divine... #spirituality of some kind... the problem was I didn't believe in anything" - Connecting with religious songs, prayer, rituals about forgiveness & bettering yourself... - Being told "just believe"... "I don't know how to do that!" - "I believe things if I see evidence for them... if I have some reason" - A scientifically curious kid - "The way I relate to the world... is through evidence" - "I don't fundamentally grasp the concept of choosing your perceptions... choosing your beliefs. I don't think I can do that" - Ontological & epistemological naturalism - "I haven't had a spiritual experience... I assume I would write it off as something explainable through psychology and physics... but I can't say for certain" - Enrolling in a #theology seminary school after graduating in physics: "wanting to understand religion... why people believe in things... I dropped out after 6 months" - "I've done everything... went to every service... went to seminary... I did all the things and still god has not appeared to me in any way... I was a little bit jealous... that certainty, that feeling of peace... you are loved by the most powerful being in the cosmos... that sounds really cool... sign me up" - "I could follow all the rules...

Pedro Vieira is a faculty member at Perimeter Institute, where he holds the Clay Riddell Paul Dirac Chair in Theoretical Physics. In this episode, he tells Lauren and Colin about his work on a kind of uber-theory that encompasses all quantum field theories, as well as what separates the easy and hard problems in this field. It's a complicated topic to be sure, but Vieira is a master of explaining complex topics with relatable examples and anecdotes – something Lauren discovered as a student when she took a course he taught. “Pedro takes some of those same concepts from graduate courses, but he paints some amazing non-technical pictures for us,” says Lauren. “No mathematical background required!” He explains why the universe might be a hologram and why, from a theoretical physics perspective, a messy bedroom can be a good thing.

Savarimuthu, and his English teacher, Rev. Fr. K.S. Arulanandam, S.J. Baskaran also reached out after our recorded conversation to extend his thanks to others who have impacted his career, including Dr. Rajaram Nityananda, a contemporary graduate student (from National Aeronautical Laboratory, Bangalore) during his PhD days in Bangalore. “Rajaram is one of the most selfless persons I have ever met,” says Baskaran. It was Rajaram who introduced Baskaran to seminal work by P.W. Anderson, a later collaborator of Baskaran's. “In 1977, H.R. Krishnamurthy arrived from Cornell and explained to us the intricacies of the Kondo phenomenon, valence fluctuation, and how to understand them using the quantum RG approach (built on Anderson's poor man's scaling theory) that Krishnamurthy, Wilkinson, and Wilson had just developed. Anderson's masterly role in modern condensed matter physics was manifest. Strong correlation physics, including Mott insulators, was in the air,” Baskaran says. Later in his career, Baskaran worked with professors who played a “lifting role” in his life, including R. Rajaraman, G. Rajasekaran, and Erio Tosatti. “I am thankful to my school, college, teachers, friends, my family, my mom Leelavathy, my dad Ganapathy, siblings, uncles, aunts, cousins, nephews, my wife Whiterose, my children, their spouses, and my grandchildren.”
