Just days before the election, the Pulitzer Prize Winner discussed the collapse of the medical system, vaccines, and what future plagues will look like.

The Broadcast is supported in part by the Alfred P. Sloan Foundation. __ Prior to the coronavirus outbreak, the Science Studios were planning an event that we wanted to call The Plague. The conversation was to be a serious exchange on the science of pandemics, particularly those that cross the species barrier, but with the vibe of a natural disaster film: the subject plausible, terrifying, but never going to happen to us. This sense of imperviousness must be the consequence of a collective amnesia that persists despite an Ebola outbreak, the scourge of HIV, the pale memory of Swine flu or Avian flu. At the event we were going to hand out little blue surgical masks as a gag. Not so funny anymore. We are indeed hosting an event called The Plague, though now the title resonates with palpable anxiety and very present grief. The disaster isn’t just plausible, it’s here. And masks are no joke. In a recent New Yorker article, the Pulitzer Prize winner Siddhartha Mukherjee wrote chillingly of the coronavirus pandemic as a scientist, a doctor, and a human in this fragile time. Our Director of Sciences, Janna Levin, invites Prof. Mukherjee to discuss COVID-19, the collapse of the medical system, vaccines, and our defenselessness against the inevitability of the next virus to jump from animals and infect humans. Siddhartha Mukherjee is a Pulitzer Prize winner, an Assistant Professor of Medicine, and a staff physician at Columbia University Medical Center. His books include The Emperor of All Maladies: A Biography of Cancer and The Gene: An Intimate History. Janna Levin is the Director of Sciences and Chair of the Science Studios at Pioneer Works. She is also a Guggenheim Fellow and the Claire Tow Professor of physics and astronomy at Barnard College of Columbia University.

Thrilled with the news that Sir Roger Penrose was awarded the Nobel Prize this morning. He shares half the prize with observers Andrea Ghez and Reinhard Genzel, who independently discovered the supermassive black hole at the center of the Milky Way. The Nobel is rarely awarded for purely theoretical work like Sir Roger’s. In pure math on paper, he discovered that black holes are inevitable and perfect. A black hole is like a fundamental particle in its flawlessness. The event horizon hiding any individuality, they become indistinguishable. Sir Roger Penrose was knighted by Queen Elizabeth II for his remarkable contributions to mathematics and physics. He is one of only twenty-two living recipients of the honor Order of Merit. Sir Roger, as he is fondly known to other physicists, is a relentlessly creative genius. He has made profound contributions to an understanding of the structure of spacetime and geometry, black holes, the unification of quantum mechanics and gravity, and the origin of our universe. His radical ideas on consciousness have provoked controversy and fascination, while his playful geometric tilings were thought to be impossible in reality. Though intuition defying, Penrose tilings ignited the imaginations of filmmakers and artists and ultimately were discovered in nature. Join Pioneer Works Director of Sciences, astrophysicist Janna Levin (author of Black Hole Blues and Black Hole Survival Guide), as she hosts Sir Roger Penrose in a conversation that will stretch across the universe, theories of consciousness, and infinity.

Everything that anyone has ever seen in the history of the universe and ever will see in the future of the universe amounts to less than 5% of what's out there. Black holes account for a modest, but fascinating, contribution to the dark sector. This century has brought the most direct, haunting observations of black holes conceivable: the first picture of a black hole shadow and a cosmic recording of the sounds of black hole collisions.

As the world continues with this weird time, we’re getting even weirder at StarTalk. Neil deGrasse Tyson, comic co-host Chuck Nice, and astrophysicist Janna Levin, PhD, are together to explore the wild, wacky world of quantum entanglement. To wrap your head around what “happens” during quantum entanglement, Janna gives us an example of splitting a wishbone at the family dinner table. Explore why, even though we can’t communicate faster than the speed of light, knowledge can work faster than the speed of light. Find out if we can use quantum entanglement to send encrypted messages. Discover more about the development of quantum computing and its delicate use of quantum entanglement. Janna tells us how we “see” quantum entanglement despite the fact that the act of looking changes the behavior. Lastly, investigate the difference between quantum entanglement and quantum tunneling. All that, plus, Chuck wants to know the answer to a simple question – “Is anything f***king real?!” =================================== About the prints that flank Neil in this video: "Black Swan” & "White Swan" limited edition serigraph prints by Coast Salish artist Jane Kwatleematt Marston.

What’s beyond the edge of the universe? Is there even an edge at all? On this episode of StarTalk Radio, Neil deGrasse Tyson answers your fan-submitted questions about the mysteries, wonders, and theories that exist on the bleeding edge of cosmology. But in order to explore the true depths of the unknown we need to bring in a little extra help – enter astrophysicist Janna Levin, PhD. We start with the basics: is the universe infinite? Janna tells us why we’re still uncertain. We explore the idea of the multiverse and the idea of our universe never having an “edge.” Could those distant galaxies we see be our own galaxy in the past? As if that’s not mind-bending enough, we haven’t even gotten to the dimensionality questions yet. Find out more about other possible dimensions. We discuss why it’s so difficult to detect other dimensions, if they’re even there in the first place. Janna and Neil help us visualize a 4th dimension. You’ll hear why adding another dimension might provide too much freedom for molecules to bind together and create macroscopic things. We also explore the idea that our three dimensions are glued to a membrane that’s floating in a higher dimensional space. We reflect on Monsters, Inc. and how the film plays with moving through different dimensions. Discover more about the shape of our universe. Could it be in the shape of a loop? We break down the Big Bang and the birth of the universe. Find out more about dark matter, dark energy, and if they’re two sides of the same coin. Janna explains why dark energy should be thought of as an invisible ocean. Investigate the “information” that lies on the surface of a black hole. We track Voyager 2’s journey into interstellar space and what that means for us back on Earth. All that, plus, Janna shares why she thinks the study of dark matter and dark energy are the most important fields of study in science today. This episode originally aired December 6, 2019.

Astrophysicist Janna Levin is back as host of StarTalk All-Stars, and this time she’s hunting black holes with her guest, Shep Doeleman, the MIT astrophysicist leading the Event Horizon Telescope project to study black hole Sgr A* at the center of our galaxy. Co-Host Matt Kirshen is back, too, and together, the three of them answer fan-submitted Cosmic Queries about black holes, quantum mechanics, general relativity and more. You’ll find out the answer to the question that’s on everybody’s mind: If light can’t escape from black holes, how can we observe them at all? In addition to hearing about event horizons, accretion disks, last photon orbits, information paradoxes and Hawking Radiation, you’ll discover why you “can’t hide behind a black hole” and how the intense gravity of a black hole bends light rays around it. Janna and Shep talk about how Einstein’s math predicted black holes even though he didn’t believe nature would allow them to exist, and how the size of a black hole is predicted by the shadow feature he also described. It’s that shadow that the EHT will be looking for, using a synchronized network of radio telescopes spanning the globe, beginning in Spring of 2017 with the first attempt to image the 4-million-solar-mass black hole that’s 25,000 light years away in the center of our galaxy – the equivalent of trying to see your favorite citrus fruit on the surface of the moon. This originally aired as a podcast on November 15, 2016.

Em 2015, um grande evento científico aconteceu no mundo. Os aparelhos da LIGO/Virgo detectaram ondas gravitacionais. De acordo com os cientistas responsáveis pela descoberta, estas ondas foram produzidas pela fusão de dois buracos negros — que tinham 14 e 8 vezes a massa do Sol. A fusão teria ocorrido há cerca de 1,4 bilhão de anos e produzido um novo buraco negro, com 21 vezes a massa da nossa estrela. Quem nos conta como esta história inusitada aconteceu é a astrofísica norte-americana Janna Levin, que demonstrou, no palco do Fronteiras do Pensamento, o som emitido pela fusão. Assiste e escute!

In her first episode as a host of StarTalk All-Stars, astrophysicist and cosmologist Janna Levin reviews the discovery of gravitational waves by LIGO, and she’s brought along the perfect science guest: Rainer “Ray” Weiss. They are joined by comic co-host Matt Kirshen Ray is Professor Emeritus of Physics at MIT and the architect of the original instrument that recently detected gravitational waves. You’ll hear how Ray, together with theoretical physicist Kip Thorne and experimental physicist Ronald Drever, joined forces to form LIGO in 1983 – although the attempt to discover gravitational waves goes back much further. Travel back in time to 1916, when Einstein’s equations upset Newtonian theory and predicted gravitational waves; to 1969, when Joe Weber announced that he had found gravitational waves, which has since been discredited; and to the early 70s, when Ray started building his prototype with help from the US Military. But this episode is about more than just history. Janna and Ray take us inside the physics of gravitational waves: what they are, how they’re formed, and how we were able to use LIGO to “hear” the sound of two 30-solar-mass black holes colliding 1.3 billion years ago, forming a new 57-solar-mass black hole. (And yes, you’ll find out what happened to the missing 3 solar masses.) Janna and Ray also answer fan-submitted Cosmic Queries, ranging from whether we could translate gravitational waves from sound into light, to what would happen to Earth if a collision of two black holes occurred in our solar system. #LIGO #GravitationalWaves #Physics This episode originally aired on October 4, 2016.
