  • StarTalk Podcast: Cosmic Queries – Black Holes and Dark Energy, with Neil deGrasse Tyson

    54:17

    On this episode of StarTalk Radio, we bring you the classic StarTalk formula that you’ve come to know and love. Neil deGrasse Tyson and comic co-host Chuck Nice answer fan-submitted Cosmic Queries on the mysteries of the universe, specifically, black holes and dark energy.

    We start with a simple question: are we sure there’s a black hole at the center of the galaxy? Neil teaches us the methods we use to measure black holes. He also reminds us of the Copernican principle. You’ll learn why the more massive the galaxy, the more massive the black hole at its center. Neil and Chuck reminisce on the movie Marooned. Discover more about electron degeneracy, neutron stars, and pulsars.

    You’ll hear if it’s possible for a black hole to re-ignite into a star once it loses enough mass through Hawking radiation. Chuck has an idea for a science fiction film about a killer black hole until Neil squashes it with some Star Trek trivia. We explore whether a black hole can warp spacetime around it. You’ll learn what happens to the gravitational well of a star if the star comes across a black hole. And, of course, it wouldn’t be a show about black holes if we didn’t talk about the movie Interstellar.

    We ponder if “Planet 9” could be a black hole. If the Earth turned into a black hole would it still orbit the sun? The answer may surprise you. We investigate what might be at the center of a supercluster. Then, we dive into dark energy. Neil explains why dark energy is still mysterious. You’ll also learn more about the Albedo effect and the Doppler shift. All that, plus, you’ll find out if dark energy has an impact on your everyday life.

  • StarTalk Podcast: Cosmic Queries – Black Holes & Dark Energy with Neil deGrasse Tyson, Part II

    48:02

    On this episode of StarTalk Radio, we bring you Part II of Cosmic Queries – Black Holes and Dark Energy. Neil deGrasse Tyson and comic co-host Chuck Nice are answering fan-submitted questions about what we know, and don’t know, about black holes and dark energy.

    You’ll hear why a black hole’s consumption of matter does not overpower the evaporation caused by Hawking radiation. Neil tells us what’s actually “evaporating” during Hawking radiation. He also tells us two remarkable facts about black holes that are sure to blow your mind.

    We discuss how a spy satellite accidently opened a new branch of astrophysics. Find out more about singularities. We investigate the singularity at the beginning of our universe and Neil explains when string theory needs to be brought to the table. Chuck shares how his son coined the word “ringularity.” We assess the possibility of black holes being used as an intergalactic highway system to connect one galaxy to the next.

    Find out more about “white holes.” Discover more about supermassive black holes. We explore the nature of photons: how they can be pulled into black holes if they’re massless and why they travel along the fabric of spacetime. Adventure back in time to Sir Arthur Eddington’s expedition to uncover how light bends around the sun.

    We ponder if dark energy and dark matter are “stuff” permeating from another universe into our own. Discover why light is trapped in our galaxy but gravity isn’t. We discuss the likelihood that intelligent life is more advanced than us. Lastly, Neil shares final thoughts on the delicate evolution of the tree of life.

  • StarTalk Podcast: Cosmic Queries – Black Hole Survival Guide

    50:13

    You’ve fallen into a black hole! Quick, what do you do? On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice investigate black holes with Janna Levin, PhD, astrophysicist and author of the new book Black Hole Survival Guide.

    Janna starts off by telling us about how her new book Black Hole Survival Guide is “dispelling misconceptions about black holes.” You’ll get a quick refresher from Neil and Janna about “spaghettification” and if there’s any way to prevent that from happening to you if you were to fall into a black hole. Janna gives us a detailed description of what happens when you fall into a black hole and why it’s “safer” to fall into a bigger black hole.

    Find out why you create a “storm” when you head into a black hole. Discover what it would be like to watch someone cross the event horizon from a distance. We discuss “time dilation.” You’ll learn what happens when there’s a “ring down” between two black holes.

    If the multiverse is true, can super massive black holes enter other universes? Can we jet between the multiverse using black hole portals? Can you stitch together a black hole and a white hole? You’ll find out what black holes have in common with Doctor Who’s TARDIS. We explore the Black hole information paradox, Hawking radiation, and whether black holes are actually an illusion made by quantum-entangled wormholes.

    Lastly, we discuss why we might have to look beyond general relativity to understand the singularity. We reflect on the Eddington experiment. All that, plus, we end by pondering the Big Rip.

    41:55

    On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are answering your fan-submitted questions on everything from discovering extraterrestrial life to traveling through dimensions. Anything that you’ve cosmically wondered about, we are ready to answer.

    To start, Neil and Chuck ponder where they would pilot the USS Enterprise if they were sitting in the Captain’s chair. You’ll learn why Neil would take a tour of his own “backyard” before setting off anywhere else. We investigate how time works as you move closer and further from the edge of the universe. Neil tells us how to kill a black hole, and the answer may surprise you.

    We discuss dark matter. You’ll hear why dark matter should really be called dark gravity. You’ll explore how we study dark matter even though it doesn’t interact electromagnetically. Then, we investigate the Higgs boson, the Higgs field, and the Large Hadron Collider. Neil shares a helpful metaphor to understand the Higgs boson that involves a Hollywood party, Chuck, and Beyoncé.

    Neil and Chuck debate which is more likely to happen – extraterrestrial contact or the ability to travel through the dimensions. You’ll learn more about higher dimensions and how they interact with the reality of other dimensions. We investigate the possibility of complex organisms existing in the liquid masses of our solar system, like on Enceladus or Europa. Neil gives us a lesson in thermodynamics in order to explain how life survives.

    Lastly, you’ll explore Low Earth orbit. Discover why people who live along the equator would weigh less than people living elsewhere. All that, plus, Neil explains how fast the Earth would have to be rotating for you to float.

  • Telescopes, Liquid Mercury, and The Death of Black Holes - Cosmic Queries

    47:21

    Terraforming mars? How do black holes die? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice answer questions about the moon, periodic table of elements, light photons, black holes and more!

    Find out about the moon’s libration and orbit. How much of our moon do we actually see? We observe patterns from Neil’s time in front of the camera. What film franchise will he wreak havoc on next? Back to the non-human stars: have modern humans always lived under the same night sky? Will there be a day when we no longer recognize the constellations?

    Why is mercury– the element, not the planet– liquid? Why does one proton make such a big difference? Discover the states of the elements on other worlds and the meaning of a “triple point.” Is it possible to terraform Mars, even though it doesn’t have a magnetic field? We explore geoengineering and how to terraform to protect against solar wind.

    Next, we talk telescopes. How much does the moon disrupt observation time? How do we combat that? We discuss the James Webb Space Telescope, Hubble Deep Field, and how astronomers combat interference. How does a light photon experience time? Does it? Can a black hole’s mass get so low it can no longer trap light? What would it look like? How does a black hole die? All that, plus, Chuck tests out new joke material on another Cosmic Queries!

  • StarTalk Podcast: Neil deGrasse Tyson Answers Your Deadliest Cosmic Queries

    47:26

    On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are ready to get morbid. We’ve gathered your fan-submitted Cosmic Queries that explore all things death, from the death of humanity to the death of the universe.

    To start, we explore what reality would be like in an apocalypse. Neil tells us what skills he thinks would be necessary to survive in a post-apocalyptic world. We discuss the importance of having the right weapon in a post-apocalyptic world. This leads Neil to air his grievances with the lightsabers found in Star Wars. You’ll find out how a meteor strike would disrupt civilization as we know it. We also explore The Walking Dead and its emphasis on the true danger of a zombie apocalypse: human relationships.

    Discover more about the death of humanity. Will we outlive the Earth? How long will humanity survive? Are artificially intelligent computers secretly waiting to take over the world? We break down the inverse relationship between intelligence and survival. Neil describes how the universe will end not with a bang, but with a whimper.

    Find out how Neil and Chuck want to die! We investigate the 2005 film War of the Worlds and how it differs from the original story by H.G. Wells. Neil recites the final narration from the film and from the original story.

    Then, we dive headfirst into black holes. We ponder if the universe could be victim to a collective hyper-massive black hole. You’ll also hear about Hawking radiation. You’ll learn the difference between disintegrating and decomposing. Lastly, we debate if human contact is necessary for your own survival. All that, plus, you’ll find out who might have been the loneliest person in history.

  • StarTalk Podcast: Cosmic Queries – Edge of the Universe with Neil deGrasse Tyson and Janna Levin

    53:26

    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.

    50:47

    On this episode of StarTalk Radio, your personal astrophysicist Neil deGrasse Tyson is back alongside comic co-host Chuck Nice to answer fan-submitted questions on a variety of topics that take us across the universe and into the unknown. You’ll find out why the universe will ultimately die “not with a bang, but with a whimper. And not in fire, but in ice.” Explore the relationship between time and space as we ponder the fabric of spacetime. You’ll even hear about the possibilities of a universe inside of another universe.

    Discover more about the concept of the holographic universe. We investigate electron microscopes and why they let us see more than light-based microscopes. You’ll also learn why matter is waves and particles. You’ll find out more about moving around in zero gravity and how you could propel a wheelchair while floating in space.

    Explore Hawking radiation. You’ll learn more about gravitational redshifts. We calculate the impact of merging black holes. We also discuss time dilation: do electromagnetic signals get warped by time dilation? Neil explains the Fermi paradox and “The Great Filter.” We ponder if the urge to explore the universe is the same urge that might destroy us.

    We try and work out a design that would make solar panels and lasers work together for wireless energy transfer. Get details why the future imagined by the 1950s-60s has been reshaped by the accessibility of information. All that, plus, Neil advocates for common core math and the importance of asking the right questions.

  • StarTalk Podcast: Cosmic Queries – Cosmic Cauldron, with Neil deGrasse Tyson and Chuck Nice

    45:55

    On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are back together to answer a cosmic cauldron of Cosmic Queries. From dark matter, to 2001: A Space Odyssey, to the size of the universe, we are answering as many fan-submitted questions as we can.

    To start, we investigate whether there’s any hypotheses that connect dark matter and black holes. We dive into science fiction as Neil and Chuck discuss their favorite depictions of aliens in film and television. We explore the lack of aliens in 2001: A Space Odyssey and Contact, why Neil’s favorite movie alien is The Blob, and why Chuck loves Alien. And, Neil and Chuck debate what space-themed tattoo they would get if they ever got one.

    Discover more about the possibility of a multiverse. We explore the “levels” of a multiverse. Then, we ponder if the universe is finite or infinite. Neil explains why the mash-up of quantum physics and general relativity can create exciting possibilities. You’ll learn about the influence space travel has on age. We also ponder if time travelers are hiding among us. Find out who Neil would want to meet if he could time travel. Then, we dive into the logistics of time travel and “causal loops.”

    You’ll hear about the mechanisms at work that help assist with Earth’s gravity. Then we ask, “Does light ever stop moving?” Neil tells us how we can use high-speed cameras to see light interact with a medium. Lastly, we discuss what technology an advanced alien civilization might have at their will. All that, plus, Neil and Chuck share their thoughts on how you’d be received if you traveled back in time and showed the people of the past your smartphone.

  • StarTalk Podcast: Cosmic Queries – Origins of the Universe with Janna Levin

    48:54

    How did the universe get to be this way? On this episode of StarTalk, Neil DeGrasse Tyson and comic co-host Chuck Nice unveil some of the subjects covered in the new StarTalk book named after our recurring segment Cosmic Queries. Theoretical cosmologist and Director of Sciences at Pioneer Works, Janna Levin, helps us break down the building blocks of the universe and how it started.

    To start things off, you’ll learn what the galaxy is made of, both objects we can see and things we cannot. We take a deep, dark dive into dark matter. How much dark matter is there? Are neutrinos a form of dark matter? Has there always been the same amount of matter and dark matter? Could there be a universe with dark matter that is parallel to ours? Find out why someday dark energy will win over the universe. We discuss why theorizing something undetectable and even unprovable may still be a scientific question.

    To kick-off questions from our patrons, we explore the Large Hadron Collider (LHC). What has it enabled us to discover? What has it not discovered yet? Could the LHC make a black hole? You’ll learn about the discovery of the Higgs particle and other elusive objects. We dive into the scientific method physicists use in predicting theories and what physicists really want.

    We also explain string theory and the harmonics of subatomic particles, and how there “can’t be nothing.” Learn why nothing isn’t as empty as you imagine and how spacetime is malleable. Is everything in the universe just a point on a string? Discover all that and more, including how quantum mechanics create spacetime, on another exciting episode!

  • StarTalk Podcast: Cosmic Queries – Cosmic Grab Bag

    45:09

    Do black holes evaporate? What’s really happening at SpaceX? What is dark gravity? On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are answering fan-submitted Cosmic Queries covering topics all across the universe.

    To kick things off, Neil and Chuck investigate dark gravity and dark energy. Could dark energy be leftover energy from an evaporated black hole? We explore how black holes eventually disappear. Neil enlightens us about the “five ages of the universe.” We ponder if dark matter or dark energy could predate the universe itself. Neil tells us why galaxies are found where dark matter has collected them.

    You’ll hear why radio waves are the preferred contact method to chat with aliens. We dive into conspiracy theories and why humans are susceptible to believing in them. Discover more about “dark-sky ordinances” and how light pollution impacts telescopes. Neil shares an example of a city and observatory working together to create less light pollution.

    Are the sizes of planets proportional to the distance between planets? We discuss the gravitational influences of planets on each other. We also discuss how many light years you would have to travel in order to see the Roman battles taking place on Earth. If time is a coordinate, why can’t we move back and forth in time? We take a look at predeterminism.

    Lastly, we explore the science of Superman. What would happen if something made the Earth rotate in the opposite direction like in Superman. Neil reminisces on his star-turn in a Superman comic. All that, plus, you’ll learn how Neil found an actual home for Krypton.

  • StarTalk Podcast: Cosmic Queries – Hubble Space Telescope, with Neil deGrasse Tyson

    53:05

    It was only supposed to last 3-5 years and it’s been orbiting for 30. Neil deGrasse Tyson celebrates the Hubble Space Telescopes 30th anniversary with comic co-host Chuck Nice and Hubble senior project scientist Jennifer Wiseman, PhD.

    You’ll learn how proposals are selected to receive telescope time. Jennifer tells us about “director discretionary time” which allows the director of the Space Telescope Science Institute to allot time for ideas and research for larger projects or projects that might not be otherwise considered in the general selection process. Jennifer tells us about an instance when director discretionary time allowed for Hubble to be pointed at “nowhere” – resulting in the Hubble Deep Field image, one of the most iconic images Hubble has ever taken. Jennifer also explains how long an idea can take from proposal to final publication.

    You’ll learn about the Hubble science team’s massive data archive that’s open for everyone. Explore some of Hubble’s most interesting discoveries. Discover more about Hubble’s work on finding supermassive black holes in the center of galaxies. We also explore the work researching the expansion of the universe.

    We ponder what the most important fields of discovery will be over the next decade. You’ll find out about Hubble’s collaborative work alongside the Juno probe to Jupiter and the New Horizons probe that went to, and past, Pluto. We also discuss the exciting world of exoplanets. Lastly, Jennifer reveals how long she thinks Hubble can stay in orbit and whether the telescope could ever be sold to a private company. All that, plus, Jennifer shares her favorite Hubble discovery over the past 30 years!

  • StarTalk Podcast: Cosmic Queries – Multiverse Madness with Max Tegmark

    49:00

    Do we live in one of many universes? On this episode of StarTalk, Neil deGrasse Tyson and comic co-host Chuck Nice investigate the theory of the multiverse with physicist and author, Prof. Max Tegmark.

    To start, we dive into the different theories and levels of the multiverse and how they differ from each other. What do people even mean when they say multiverse? Is it just more unidentifiable parts of space or whole parallel universes? You’ll learn about inflation theory and quantum multiverses. We ponder whether there may be an Evil Chuck out there lurking in some other universe?

    Discover the idea behind infinite infinities. What does it mean for one infinity to be bigger than another infinity? We explore Einstein’s theory of general relativity and how it relates to infinity. Can you have infinite infinities within a finite universe? Could parallel universes exist within a multiverse? We investigate our definition of the universe and if there could be more space beyond it.

    How does the multiverse affect our universe? Is there any observational evidence to suggest it actually exists? Does dark energy have anything to do with it? We get into how to test seemingly untestable theories and how exploring these holes in our knowledge gave us quantum mechanics. You’ll also learn how a multiverse would even begin and what might exist between universes. Find out about Hilbert space and decoherence. Would Evil Chuck know about our own Good Chuck? Many more questions answered on another episode of StarTalk!

  • StarTalk Podcast: Cosmic Queries – Kitchen Sink Edition

    45:22

    What are your burning questions about the universe? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice answer Patrons’ flaming-hot questions about the universe covering stars, black holes, gravity, philosophy... everything but the kitchen sink!

    What is Neil’s favorite star? We dive into some of our galaxy's most interesting stars and the mysterious phenomena around them, constellations, and whether the star of Bethlehem was a supernova. You’ll learn about ancient global astronomy through history. Shifting to our own solar system, find out if there is a mysterious ninth planet in our solar system beyond the light of our sun.

    Discover the difference between how gas giants and stars form. We explore more black holes and explain how Hawking radiation works. How could black holes eject particles if nothing can escape the event horizon? Does a black hole have a memory? We talk Einstein, matter, and antimatter.

    Going deeper and deeper, we answer the question: If energy and matter are equivalent, do modern theorists believe that free will exists? We break down subjectivity and the role of science within humanity. You’ll learn about neuroscience and the inception of thoughts in the brain. How does the subconscious mind work? We explore the idea of free will, whether or not we are in a simulation, and a quantum approach to predetermination.

    Could we use stars as an alchemy table to forge elements we want? What other sci-fi concepts do our Patrons have cooked up? You’ll learn why gravity is such a weird force. Is there another paradigm to talk about gravity? Are there other dimensions or dark matter that work to impact gravity? The more we learn the more we know about our own universe. But above all, we thank the programmer of our simulation for free will and yet another episode of StarTalk!

    51:57

    Thanks to Wix for sponsoring this video! Create your website now:

    It’s time for another episode of Cosmic Queries, where your own personal astrophysicist Neil deGrasse Tyson answers, sight unseen, fan submitted questions chosen by his co-host. This week, Chuck Nice asks Neil questions on a wide variety of topics that we couldn’t answer in other episodes, from alien plant life, to colonizing Mars, to whether velocity could be considered a dimension.

    You’ll find out if the constellations would look different from Saturn, whether there’s a north pole to our universe, and why astronomers got the Mily Way’s north pole wrong in the first place. Discover why a stable black hole can’t exist inside a star, and how the expansion of our Sun will affect the Earth. You’ll learn how scientists knew to leave gaps in the periodic table of the elements, and why the moon is spiraling away from the Earth at 5 inches a year. Neil speculates on what the bright spot on the dwarf planet Ceres might be, whether we’ll explore Jupiter’s moon Europa in our lifetimes, and if we’ll find life in its subsurface ocean.

    You’ll also hear how NASA inventions led to grooved highway pavement and safer, cheaper LASIK surgery. On the lighter side, Neil and Chuck talk about Neil’s famous vests, the Ship of the Imagination from COSMOS: A Spacetime Odyssey, YouTube’s famous “Double Rainbow Guy,” and the wrestling move Neil always wanted to invent which he calls the “Double Tidal Lock.”

  • The Hidden Chemistry of Everything with Neil deGrasse Tyson and Kate the Chemist – Cosmic Queries

    50:52

    Is chemistry truly everywhere? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice answer fan questions about chemistry with Kate Biberdorf, aka Kate the Chemist. Discover the chemical reactions that make our world work!

    What is fire? We break down combustion reactions and how– scientifically– dragons could breathe fire, if they existed, that is. We discuss Kate the Chemist’s fiction series as well as her new book for adults, It's Elemental: The Hidden Chemistry of Everything ( Dive into the periodic table through the eyes of a chemist and an astrophysicist. Astrochemistry anyone? We discuss where we can find lithium on Earth and why not all the iron is in Earth’s core. Did some iron get distracted?

    Why did many scholars practice alchemy? Was it just in the pure pursuit of science? Learn some fun chemistry experiments you can do at home. What is stoichiometry? What is catalysis? You’ll learn about functional groups and how an element’s state impacts its reactions. Why don’t we power cars using hydrogen?

    Find out about salt ionization and how salt water works. Does cooking food change its chemistry? What is caramelization? Are we on the cusp of discovering a new branch of chemistry? How does an atom work? As a society, have we reached a scientific plateau? We also discuss if there is a chemical solution to combating climate change?

  • Launching the Inspiration4 with Neil deGrasse Tyson, Chris Mason, & Sian Proctor – Cosmic Queries

    42:20

    What did we learn from the first all civilian mission into orbit? Neil deGrasse Tyson and comic co-host Chuck Nice explore SpaceX’s recent launch, the Inspiration4, with biophysicist Dr. Chris Mason and geoscientist and pilot Dr. Sian Proctor.

    Can the human body adapt to space? We discuss how humans respond to spaceflight, the biomes found within a spacecraft, and microbes in space. What happens when we only send the same kid of people up into space? What does a geoscientist think when she looks out the spacecraft window? What does it mean to be classified as civilians? We ask Chris what he is looking for in his tests. What do spaceflight and roller derby have in common?

    What do you pack when you go to space? We break down the perseverance it takes to get to space and what sort of setbacks Sian saw on her way. We answer more questions like, how does zero G affect perfusion ratios in the lungs? Are there consequences? Do people in space really become taller? Is there a way to make this permanent? Discover the hardiness of bacteria in space and concerns about microbes from other planets. Could we contaminate the Earth with some Martian microbe? As space becomes more accessible is there a difference in training?

    What changed about Sian after seeing Earth from space? Find out about Neil’s experience in a centrifuge. What did the Inspiration4 team eat in space? Are there long-term effects of being away from Earth’s magnetic field? How do you operate a Crew Dragon capsule? All that, plus, find out our wishlist for future space stations: What would you want to have in space?

  • StarTalk Podcast: Cosmic Queries – Planets and Stuff with Neil deGrasse Tyson

    51:37

    On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Paul Mecurio ( answer your Cosmic Queries on planets and more from the YouTube Studios in New York City.

    We start with one of the most inciting questions: if we had an ocean or bath tub large enough, would Saturn float? Neil tells us about the interplanetary workings of Saturn and why a “piece” of Saturn would float in a puddle of water. You’ll hear why Saturn’s rings might only be temporary. We discuss the density of water and the science of building boats. Discover more about the Titanic and the density of ice.

    Then, we explore the world of neuroscience. Neil tells us why he loves tracking the progress of modern-day neuroscience. We ponder if eventually psychologists will be replaced by simple brain adjustments once we can locate what parts of the brain cause certain emotions and behaviors. Find out the history behind the phrase “we only use 10% of our brains” and how it’s been flipped from the original statement.

    We discuss if Jupiter is a failed star. Find out what our solar system would be like if we were a two-star system. Learn more about thermonuclear fusion. We dip into tidal science and investigate tidal bulges, the Moon’s relationship with the tides, and we explain why we’re actually traveling “through” low tide and high tide. All that, plus, Neil shares why putting humans on the Moon was the valuable cosmic perspective we’ve encountered yet.

  • StarTalk Podcast: Cosmic Queries – Life on Venus, with Neil deGrasse Tyson

    47:54

    Is there life on Venus? Neil deGrasse Tyson, comic co-host Paul Mecurio, and astrobiologist David Grinspoon investigate the recent discovery of phosphine gas in Venus’s atmosphere and answer your Cosmic Queries.

    We gathered up all your Cosmic Queries about the recent news and we start with the big question: Does this mean there’s life on Venus? Could there be a habitable zone? David tells us why the answer is…maybe. We explore the discovery of the phosphine gas and the possible explanations behind its existence in Venus’s atmosphere.

    You’ll explore what’s next after a discovery like this. Can we bring samples back to Earth? David gives details on the complexity of a mission to the Venusian atmosphere. We also explore Venus’s volcanoes and its geologically-active surface. David explains why, if we want to know what’s going on in the atmosphere, we have to know what’s happening on the surface.

    Then, we take a look at Earth: Can we use Earth to help us deduce what’s happening on Venus? We ponder the best way to search for life in the universe. We also ponder whether life needs water to thrive or if life just needs liquid. David gives us the top three gases that could be used to signify life elsewhere.

    Find out why Venus’s atmosphere is so thick. We discuss Venus’s runaway greenhouse effect and the viscous circle of its carbon cycle. We also wonder if a probe from Earth might have introduced microbes to Venus’s atmosphere. All that, plus, we ask the very important question: Is the Wicked Witch of the West actually from Venus?

  • StarTalk Podcast: Cosmic Queries – Fan Grab Bag

    52:22

    On this episode of StarTalk Radio, we’re celebrating you! The fans! Neil deGrasse Tyson and Chuck Nice are answering a special batch Cosmic Queries submitted by some of our most supportive fans.

    Before we dive into questions, Neil and Chuck reflect on IQ tests. What happens when the person taking the test is smarter than the person who wrote the test? You’ll learn what it was like for Neil to be a student. Then we dive into the questions. Why are there so many spirals in nature? Neil tells us about his experiences filming Cosmos in a redwood forest and seeing spirals along the trunks of trees. You’ll learn about spiral galaxies and “density waves.”

    Then, we investigate the rise and fall of the Arecibo Observatory. Neil gives us a history lesson on the significance of the telescope and it’s functionality. We discuss the slow demise and eventual shut down of the telescope. You’ll also learn about the Five hundred meter Aperture Spherical Telescope in China that’s currently the world’s largest filled-aperture radio telescope. Neil also explains why the plight of the Arecibo Observatory is a metaphor for science in America.

    We ponder if machines can ever truly make art. Neil gives us his definition of art and why he thinks the only way for a machine to make art is to be a genuine artificial intelligence. What’s the most fascinating thing we’ve discovered in the known universe? Neil tells us why you can’t beat black holes. You’ll hear how scientists first discovered signatures of a black hole. All that, plus, discover more about the expansion of the universe and if it will end with the annihilation of spacetime.

    In this episode, we’re spotlighting Cosmic Queries submitted by Patron Joel Cherrico. If you would like to have your questions featured in an episode through audio/video interaction with Neil, check out our Custom Queries reward on Patreon.

  • A Cosmic Crisis - Cosmic Queries

    53:28

    How do we know the age of stars? On this episode, Neil deGrasse Tyson and comic co-host Paul Mecurio answer fan questions about stars, black hole collisions, the speed of light, and the present crisis in cosmology.

    Nothing can travel faster than the speed of light. How does the universe do it? We explore the special theory of relativity, the speed of light, and travelling using wormholes and warp speed. Are there speed limits in the universe? Does the speed of light ever change? During this journey through the universe you also learn about Paul’s journey from lawyer to comedian.

    How do astronomers know the age of distant stars? We confront just how short our lifetimes are compared to stars. How do we figure out the lifecycle of a star when all we have is the equivalent of the snapshot in the star’s life? How would an insect learn about humans if it only lived for a day? What would they think about hospitals or brushing our teeth? Find out about stellar evolution and how theorists and observers combine forces to put together information on the stars.

    In a lightning round, we break down what’s going on with the crisis in cosmology, who Neil thinks is right, and whether this stalemate will usher in some new physics. What happens when two black holes collide? Find out about LIGO, gravitational ripples, and angular momentum. Why send a probe a great distance when we may invent something in the meantime that could beat the original probe? Can anything pull you at the speed of light? How much of earth’s resources could get used to colonize Mars? We discuss in-situ resource utilization, terraforming, and the advantages of colonizing Mars. All that, plus, why Jar Jar Binks is actually a good actor…

  • StarTalk Podcast: Cosmic Queries – Comet NEOWISE with Neil deGrasse Tyson

    52:49

    If you were lucky enough this past July, you might have caught a glimpse of Comet NEOWISE before it left Earth’s view. If not, don’t worry, we’ve got you covered. On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Negin Farsad are answering fan-submitted Cosmic Queries about Comet NEOWISE and more with cosmochemist and author Natalie Starkey, PhD.

    First discovered in March this year, you’ll learn a little background about NEOWISE. Where did it come from? Can we be sure that it came from our solar system? Natalie tells us why speed can be a strong signifier of where a comet is coming from. You’ll learn what it means to be a “long-period” comet. You’ll also learn why comets have elongated orbits instead of circular orbits.

    Next, Neil gives us some history on the Oort Cloud. We take a look at how NEOWISE got its name and the naming process of scientific objects. Neil also shares some interesting information about Halley’s Comet that you might not know.

    Natalie tells us what unanswered question about comets she most wants to see answered. We ponder whether comets and/or asteroids could have delivered the building blocks of life to Earth. Explore amino acids on comets and in space. Would we find amino acids on NEOWISE? Examine the possibilities of Earth having “interstellar water.” And, you’ll also investigate if we can harvest water from comets to solve water crisis and famine here on Earth.

    We discuss how different chemical compositions change the color of comets. You’ll hear why a comet’s “tail” can be a misnomer. Lastly, find out what it means for a comet to be “dead.” All that, plus, Natalie takes us through the scene of two comets colliding with each other and we debate if a probe could hitch a ride on a comet to a world beyond.

  • StarTalk Podcast: Cosmic Queries – Volcanoes, with Neil deGrasse Tyson

    47:42

    Is the super volcano under Yellowstone going to erupt? What’s the difference between lava and magma? Neil deGrasse Tyson, comic co-host Chuck Nice, and volcanologist Janine Krippner, PhD, answer fan-submitted questions about volcanoes.

    How many active volcanoes are in the world right now? Janine tells us about the Smithsonian Institution’s Global Volcanism Program which keeps tabs on all the active volcanoes in the world. Find out how the Ice Age wiped the volcanic record clean. You’ll learn the difference between magma and lava. Janine tells us what’s really going on with the super volcano underneath Yellowstone National Park. You’ll find out why Janine isn’t a fan of the term “super volcano.”

    We take it back to the basics: why do volcanoes explode? We explore why eruptions are important, and, why volcanoes play an important role in our ecosystems. We discuss how volcanoes contribute to climate change – and how they pale in comparison to human activity.

    Discover more about the different types of eruptions. We ponder whether proximity to geological activity enhances people’s desire to study it. Janine shares why robots won’t be taking the jobs of volcanologists any time soon. You’ll hear about lava – if it moves so slowly, how is it so destructive? You’ll also learn about “pyroclastic flow.”

    Lastly, we investigate how many dormant volcanoes have the potential to cause mass devastation on Earth. Janine shares why there’s uncertainty around predicting eruptions. Is society ready for a massive eruption? All that, plus, Janine tells us what volcanoes can teach us about the inside of our planet.

  • StarTalk Podcast: Cosmic Queries – New Year

    46:11

    Happy 2021! On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are looking at the year ahead, reminiscing on the year past, and answering fan-submitted Cosmic Queries.

    Before we get into questions, Neil and Chuck chat about the turbulent year that was 2020. We explore other turbulent times in history including 1968 and World War II. Neil tells us why he thinks NASA saved 1968 with Apollo 8. We look back on 2020’s total solar eclipse and The Great Conjunction. Neil explains why humanity’s handling of COVID-19 was a testing ground for an actual alien invasion.

    Then, we dive into some questions! Can a light particle travel through space unhindered? Does it travel forever? You’ll find out why, in our universe, the answer is no, but, in an alternate universe that’s static, the answer is yes. Discover more about the speed of light. What if the speed of light was different? Neil tells us why, if the speed of light was different, everything would change.

    You’ll hear the advantages and disadvantages of living on or near a gas giant. We explore Jupiter’s moons Europa and Io. Could we live on these moons? Could we live on Jupiter or Saturn? All that, plus, take a peak behind-the-scenes when a fan asks Neil how StarTalk originally started and how we ended up where we are today.

  • StarTalk Podcast: Cosmic Queries – Proving Einstein Right

    52:27

    Albert Einstein is, well, Albert Einstein. But, was he right? It seems like a silly question, but, in fact, there’s some history behind it. On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are investigating what it took to prove Einstein right, with Dr. Jim Gates, theoretical physicist and Professor and Center Director of the Brown University Theoretical Physics Center. Jim is also the co-author of Proving Einstein Right: The Daring Expeditions that Changed How We Look at the Universe.

    We start with some history. Jim tells us about Einstein’s discoveries about space and time in 1905. You’ll learn about the “happiest thought” of Einstein’s life. We discuss how he came to his theory of general relativity and theory of special relativity. You’ll also learn why, even though he first started working on the ideas in 1905, it took him over a decade to get them right.

    Find out what it takes to provide evidence for mathematical theories in the real world. We discuss Einstein’s exposure to the real world and how that informed his thought process. Jim explains why being a scientist involves swimming in a sea of information. We ponder if Einstein ever thought his theories were incorrect, and Jim tells us why math is magical.

    Then, we answer fan-submitted Cosmic Queries! Is general relativity incompatible with quantum mechanics? If so, why? Is there a bigger idea that encompasses both ideas? We dive into String theory and how that might play into the equation. We investigate “gravitons” and how their existence would re-shape science.

    Are the strings in String theory made of something? We explore the cosmic microwave background and debate if a cosmic gravitational background could also exist. Lastly, you’ll hear why some stars in the night sky might be duplicated due to the bending of light. All that, plus, we answer the most important question of all – who has a better mustache? Neil deGrasse Tyson or Albert Einstein?

  • StarTalk Podcast: Cosmic Queries – Oumuamua

    45:44

    On this episode of StarTalk Radio, Neil deGrasse Tyson, comic co-host Chuck Nice, and cosmochemist and author Natalie Starkey answer fan-submitted Cosmic Queries about ‘Oumuamua, the first detected interstellar object that passed through the solar system. 

    To start, Chuck wonders why we even study space rocks if they’re all the “same.” Natalie tells us how studying space rocks helps us understand our solar system when studying Earth only tells us so much. You’ll learn why asteroids might be the leftover building blocks from planets. We ponder what might be hiding in the Oort Cloud and why ‘Oumuamua is basically an interstellar vagabond. 

    You’ll find out more about ‘Oumuamua’s discovery and how it got its name. We also talk about the only other interstellar object we’ve documented (so far). What is the likelihood we will see another interstellar object? Natalie explains the difficult task of looking in the right place at the right time since interstellar objects can, literally, come from anywhere. 

    How do we differentiate an interstellar comet from a comet that came from the Oort Cloud? We explore the idea of panspermia. Could life survive such a perilous journey similar to ‘Oumuamua’s? Lastly, Natalie helps us understand why ‘Oumuamua’s shape is so peculiar. All that, plus, we ask the obvious question: was it sent by aliens?

  • Living in a Simulation with Neil deGrasse Tyson and Nick Bostrom – Cosmic Queries

    55:54

    Are we in a simulation? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice take a deep dive into simulation theory, consciousness, and free will with Oxford theorist Nick Bostrom. Is this The Matrix?

    Why do we even think we may be in a simulation? We get into the reasons why the simulation hypothesis may or may not be true. Are there simulations within simulations? What is an ancestor simulation? We explore different types of simulations and what the purpose may be. Could higher beings be making simulations the same way we make video games and movies for entertainment? Is there any evidence we are in a simulation?

    How would you simulate the human brain and everything it experiences? Would you have to simulate the whole universe? We answer patron questions like: What sort of energy would society need to make a simulation? We break down the Kardashev Scale, superintelligence, and the Death Star. What is panpsychism? We explore what consciousness means and what simulation means for our free will. Could a computer ever be conscious?

    We get theological with it as we ask: If we are in a simulation would we have free will? Or a god? If we are in a simulation, why are the people running it so patient? We explore computation, algorithms, and what sort of technology would be needed. Is a computer inevitable? Could we simulate an exact replica of our universe to be able to predict the future? All that, plus, find out what’s going on in Neil’s Sims games.

  • StarTalk Podcast: Cosmic Queries - Fermentation

    51:22

    All you have to do is let it sit and watch the science happen. On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are answering fan-submitted Cosmic Queries with Arielle Johnson, PhD, science officer on Good Eats, food writer, and formerly the in-house R&D scientist at Noma, ranked the world’s best restaurant in 2010, 2011, 2012, and 2014.

    What is fermentation? You’ve heard of fermenting wine, beer, and cabbage, but how does it work? Arielle tells us how fermented foods made their way into our diets. You’ll learn how sugar plays a big part in the fermentation process. What’s the difference between fermented vs. pickled?

    Why doesn’t fermented food make you sick? Why can we eat moldy cheese and not eat moldy bread? We investigate the popularity of kombucha. You’ll learn how kombucha is made. We explore some of the health benefits of kombucha and if there’s any substance behind the claims. You’ll learn if NASA has ever dabbled in fermentation aboard the International Space Station.

    How common is fermentation in the wild? Do other mammals eat fermented fruits or vegetables? We also investigate why vinegar works as a natural preservative. Discover more about the importance of “water activity.” You’ll hear about mulled wine and rice wine. Lastly, we dive into sourdough bread, we ponder whether algae are the food of the future, and we ask Arielle if you can use fermentation to invent new foods.

    39:53

    Take our survey for a chance to win a copy of our Cosmic Queries book AUTOGRAPHED BY NEIL DEGRASSE TYSON!

    What will first contact with aliens be like? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice say “Happy New Year!” by answering a grab bag of fan questions about aliens, string theory, moon landing skeptics, and more!

    Will our first contact with aliens mean doom for us all? We explore why that might not be the case. Is it all just a projection of ourselves? Are we all just worms on a street? Is it true that string theory requires ten dimensions? Are particles points or strings? Learn about electrons, electricity, and matter in higher dimensions. What is a positron?

    If we wanted to create a second moon how would we do it? We explore how much stuff it would take and the impact of gravity. Is it possible to make anything other than a sphere? We ask: Why is there so much skepticism about the moon landing? Is there any believable way it could’ve been faked? We break down moon landing deniers and why they’re right– just kidding, they’re completely wrong.

    We explore plans to return to the moon and the commercialization of space travel. Are there any resources on the moon that we could use? Could we make Disneyland on the moon? Could people live there? At 1% of Earth’s mass, it’s a small world, after all. Discover NASA’s history with commercial industries and how exploration and research often pave the way for the industry. All that, plus, hear Neil’s reflections on the past year, and hopes for the new one.

  • James Webb Space Telescope with Neil deGrasse Tyson and Natalie Batalha — Cosmic Queries

    56:43

    What’s the deal with the James Webb Space Telescope? On this episode, Neil deGrasse Tyson and comic co-host Matt Kirshen learn about the JWST and what new things it will help us discover with NASA astronomer Natalie Batalha and filmmaker Nathaniel Kahn.

    Will this telescope help us find habitable planets? Another Earth perhaps? We discuss Nathaniel’s new documentary, The Hunt for Planet B, which follows scientists as they research and build humanity’s largest and most cutting-edge space telescope to date. Why was it delayed so much? Where is it being launched? What new engineering and feats of science were invented? What is it like to put your entire career into one object?

    Next, we speak with Natalie and her journey to work on the JWST. Find out the two main objectives of the JWST and how it may help us glimpse into the past. We get into spectroscopy and how JWST uses infrared light. What’s the difference between JWST and other space telescopes we’ve launched in the past? Why are we looking for exoplanets? Are we planning to leave? We get into our patron’s questions: How big would a telescope have to be to see cities on other planets? Why do we choose to send up one single telescope instead of an array? What does Natalie want to discover? We explore best case and worst case scenarios. What happens if it doesn’t deploy properly?

    What will JWST see that Hubble can’t? What would be the most exciting or surprising thing for it to detect? Can the telescope detect life? What about extrasolar objects like ‘Omuamua? What is the mechanism for how our moon formed? What is the usable lifespan of JWST? And finally, how will JWST further shape future generations’ vision of this world, just as Hubble had for the last generation of scientists?

  • The Multiverse Hypothesis Explained by Neil deGrasse Tyson

    10:03

    The multiverse hypothesis or theory holds that a group of multiple universes (possibly infinite universes) comprise everything that exists: The entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The renowned astrophysicist Neil deGrasse Tyson explains in detail the multiverse hypothesis.

    However, prominent physicists are divided about whether any other universes exist outside of our own. Some even go as far as to say that the multiverse is not a legitimate topic of scientific inquiry. Because it can not be empirically falsified. But Neil deGrasse Tyson among other prominent cosmologists, thinks that given our understanding of quantum mechanics and the theory of General relativity, the possibility of the existence of the multiverse is a legitimate scientific hypothesis.

    Steven Weinberg said that if the multiverse existed, the hope of finding a rational explanation for the precise values of quark masses and other constants of the standard model that we observe in our Big Bang is doomed, for their values would be an accident of the particular part of the multiverse in which we live.

    Some scientists analyzed the data from the Wilkinson Microwave Anisotropy Probe, an uncrewed spacecraft operating from 2001 to 2010 that measured temperature differences across the sky in the cosmic microwave background, the radiant heat remaining from the Big Bang, and claimed they found evidence suggesting that our universe collided with other parallel universes in the distant past.

    However, a more thorough data analysis from the Wilkinson Microwave Anisotropy Probe and from the Planck Satellite, a space observatory operated by the European Space Agency from 2009 to 2013, which mapped the anisotropies of the cosmic microwave background, did not find any statistically significant evidence of universe collisions. there was no evidence of any gravitational pull of other universes on ours either. And to add insult to injury to the proponents that the multiverse hypothesis has been backed up by statistical evidence, the Planck satellite, has a resolution three times higher than the WMA Probe.


    Our brains are not evolutionarily equipped to intuitively understand quantum mechanics and large scale cosmic phenomena. But Neil deGrasse Tyson with his usual wits explains the multiverse hypothesis in layman's terms.

  • StarTalk Podcast: Cosmic Queries – Lunar Geology

    57:11

    On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are answering fan-submitted Cosmic Queries about lunar geology alongside planetary scientist Raquel Nuno. And as Raquel says, she’s here to change your mind about the Moon!

    As it turns out, we don’t know very much about the Moon. Raquel explains how the Moon has been a celestial witness to everything Earth has experienced. Learn about some surprising discoveries we’ve made from moon rocks and other samples. You’ll hear how our views on the Moon changed from it being a piece of primordial dust and rock to a place with an incredible geologic history. We also discuss why we currently can’t go back to the Moon.

    Next, we explore the Moon’s craters and why Earth has far fewer craters. What would we find if we extracted a core sample from the Moon? Raquel tells us about finding Moon samples on astronaut space suits. Are there still bacteria alive on the Moon left from the Apollo missions? We explore where the ice on the Moon comes from, and Raquel gives us details on creating “water out of thin space.”

    You’ll learn more about Theia and the “giant-impact” hypothesis. Explore the Moon’s magma ocean of the past. Uncover the “truth” about the dark side of the Moon. Ponder what would happen if the Moon broke apart. Lastly, we discuss the true color of the Moon, and, whether we can terraform the lunar surface. All that, plus, we ask, can a moon have a moon?

  • Neil deGrasse Tyson Explains Heat vs. Temperature

    11:14

    What’s the difference between heat and temperature? In this StarTalk explainer, Neil deGrasse Tyson and comic co-host Chuck Nice investigate the important difference between heat and temperature from an astrophysics standpoint and how that impacts our environment.

    We take a closer look at how atoms determine the temperature of an object. How does an atom’s vibration impact temperature? What about its mass? Can a single atom have both a temperature and a heat? Find out why this distinction is important when Neil dives into how temperature and heat interact with our environment. What has more heat, your morning cup of coffee or the ocean?

    You’ll also learn how climate change works with heat and temperature. What is the energy budget of a climate system? Is it how much you spend on air conditioning? How do air conditioners even work anyway? Discover where energy lurks all around us with your personal astrophysicist!
