  • Neil deGrasse Tyson Explains the Simulation Hypothesis

    7:53

    Neil deGrasse Tyson and comic co-host Chuck Nice are here (or are they?) to investigate if we're living in a simulation. We explore the ever-advancing computer power and how that impacts the simulation hypothesis. Chuck wonders if a simulation universe has anything to do with us not being able to travel at the speed of light. You'll learn about Bayesian statistics. Lastly, Neil tells us how he was ready to embrace the simulation hypothesis until he came across a certain idea that changed his mind.

  • Neil deGrasse Tyson: Its hard to argue that we arent living in a simulated world

    2:35

    Neil deGrasse Tyson - like Elon Musk - says it's hard to argue that we aren't living in a simulation, explaining that with the computing power to create worlds - that can create worlds, that then create more worlds - the likelihood that we're living in the real world is, at best, slim.

  • The Future of Colonizing Space- Neil deGrasse Tyson- WGS 2018

    1:19:52

    Space missions need to have a defensive component or economic benefit. With economic returns often uncertain, space programmes have tended to be led by governments, because only they can invest in programmes that have a long-term pay-off, whether economic or geopolitical. When it comes to saving humanity from an asteroid impact, Tyson stressed that rather than establishing colonies in space, we would be better to try to deflect the asteroid.

    تحدث نيل ديغراس تايسون، عالم الفيزياء الفلكية، أن البعثات الفضائية تُطلق عادةً إما لأغراض دفاعية أو اقتصادية لتبرير غايتها. وفي غياب ضمانات العائد الاقتصادي بالنسبة إلى القطاع الخاص، تتولى الحكومات إدارة جميع برامج الفضاء لما تملكه من قدره على الاستثمار في برامج ذات عائد طويل الأجل، سواء كان لهذا العائد بُعد اقتصادي أو جيوسياسي. أما بالنسبة إلى الدعوة لبناء مستعمرات على سطح الكواكب الأخرى تحسبًا لأي دمار قد يحلّ بكوكب الأرض نتيجة تعرضه لاصطدام نيزك، قال تايسون إن تحويل مسار النيزك يظل هو الحل الأمثل في هذه المرحلة

    The Oh My God Particle


    The idea that our reality is a simulation is not as far-fetched as you may think. Many philosophers, scientists and tech-billionaires are seriously considering not just the possibility but the high probability that our civilization may be a program being run by another, more advanced alien civilization.

  • The Great Filter Hypothesis With Neil deGrasse Tyson - The Solution to The Fermi Paradox

    10:02

    Is there life beyond Earth?

    No one knows for sure.

    Beloved astrophysicist Neil deGrasse Tyson makes a compelling case for why if even intelligent alien life exists elsewhere in the Universe, it is extremely rare. Neil Tyson mentions the fact that the evolutionary tree of life on Earth suggests intelligence is not that important when it comes for survival.

    Neil deGrasse Tyson also talks about the Hawking argument that basically says extraterrestrial visits on Earth would not be in our best interests.

    Debate about the probability of finding signals of advanced life varies widely. In 1961, astronomer Frank Drake created a formula (which became known as the Drake Equation) for estimating the number of potential intelligent civilizations in the galaxy. He calculated there should be at least 10,000 technology producing civilizations in the Milky Way galaxy alone.

    Most of the variables in the equation continue to be rough estimates and subject to uncertainties. But an interesting conundrum to Drake's speculative answer for the number of intelligent civilizations in the galaxy is the Fermi paradox. Posited by Italian physicist Enrico Fermi, it asserts that if another intelligent life form was indeed out there, why have we not seen it by now?

    While it might seem as extreme hubris to expect humans to see evidence for the existence of intelligent alien life, considering how many star systems there are in our galaxy alone, and if indeed intelligent life is prevalent, we should expect to see some sort of data from alien origin.

    Another hypothesis that explains the Fermi problem is the Great Filter. Which basically poses that something leads to the destruction of civilizations before they manage to master intragalactic communication and interstellar travel.

    Even if we knew for certain the Great Filter is a correct theory, we still wouldn't know when or at what stage of life it emerges. For example a great filter could be acting to prevent non living matter to undergo Abiogenesis. Which is the first stage of life. Or a great filter could show up in later stages of life. Such as our stage where intelligent beings begin to create technology and hope to one day colonize the galaxy.

  • Neil deGrasse Tyson | Why We May Not Live In A Simulation

    9:52

    Philosopher Nick Bostrom's Simulation Hypothesis argues that at least one of the following propositions is true:

    1. The human species is very likely to go extinct before reaching a “posthuman” stage;

    2. Any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof);

    3. We are almost certainly living in a computer simulation. It follows that the belief that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation.

    Astrophysicist Neil deGrasse Tyson, once a believer in the likelihood of our living in a simulation, has now arrived at the conclusion that there is only a 50/50 chance that we are in a simulated reality. He came to this realization after reading the book The Doomsday Calculation by author William Poundstone who studied physics at MIT.

  • Rizwan Virk | The Simulation Hypothesis | Talks at Google

    50:24

    2019 marks the 20th anniversary of what is arguably one of the best Science fiction movies ever made - The Matrix. It popularized an ancient idea that the world we live in may not be real. In other words, our world is just an illusion, a simulation -- a video game.

    So, Are we really living in a video game?
    Game industry veteran Rizwan (Riz) Virk believes this could be true.

    Rizwan (“Riz”) Virk is a successful entrepreneur, angel investor, bestselling author, video game industry pioneer, and indie film producer. Virk currently runs Play Labs @ MIT ( a startup accelerator for playful technologies held on campus at the MIT Game Lab and Bayview Labs (
    Virk’s books include: Startup Myths and Models: Secrets They Don't Teach You at Stanford Business School, from Columbia University Press (2020), Zen Entrepreneurship: Walking the Path of the Career Warrior (2013), and Treasure Hunt: Follow Your Inner Clues to Find True Success (2017).

    Virk’s video games have been played by millions, including Tap Fish, and games based on TV shows like Penny Dreadful and Grimm. Virk has been an investor in many video game companies, including Telltale Games (creator of narrative games based on The Walking Dead and Game of Thrones), Disruptor Beam (creator of Star Trek: Timelines game), Pocket Gems, Tapjoy, Sliver.tv, and Discord.

  • Things You Thought You Knew with Neil deGrasse Tyson

    48:42

    Mass? Weight? Density? There are some things you thought you knew and on this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are here to investigate what we know and what we thought we knew.

    We start with mass, weight, and density. If you’re trying to get in shape you need to lose weight, right? Neil deGrasse Tyson says wrong. Neil tells us why when you want to get in shape, you need to lose mass. You’ll learn why a weight-loss book written by a physicist would just be one sentence. We explore the difference between mass and weight and why weight is all about forces. Find out why heavy cream is lighter than skim milk. We explore how the hull of a ship keeps the ship buoyant. All that, plus, Neil explains why, if you want to lose weight quickly, just head to the Moon and hop on a scale.

    Then, we move on to another seemingly simple question: Why does ice float? Neil explains why peculiar things happen to water when it changes state. We explore what happens when water freezes. Chuck gives a demonstration of why you usually see 10% of ice above water. You’ll learn why the arctic ice sheets float on the water. And, why the ice we need to worry about is the ice on land and the “runoff.” We discuss the power of freezing ice (which leads to bursting pipes). Find out more about the density of water. What if bodies of water froze from the bottom up? Neil tells us how a certain property of water protects aquatic life over the winter.

    Lastly, we turn our attention to space. How much do you weigh in space? Neil tells us why we should be thinking about how much mass something contains instead of how much something weighs. You’ll learn why your weight in water is basically zero. Why are astronauts weightless in space? Neil explains how Sir Isaac Newton discovered orbits. Find out why most energy from a rocket launch is not used to get the rocket into space. All that, plus, we explore the science of Ad Astra, The Expanse, and 2001: A Space Odyssey.

  • StarTalk Podcast: COVID-19 Update, with Neil deGrasse Tyson

    42:48

    This episode was recorded on April 23, 2020. Note – This episode contains factual discussions of the ongoing COVID-19 pandemic and may contain certain topics and discussion of statistics and information that might cause distress.

    On this episode of StarTalk Radio, Neil deGrasse Tyson gets and update on the ever-evolving COVID-19 pandemic from Dr. Irwin Redlener, Director of the National Center for Disaster Preparedness.

    To start, you’ll learn what constitutes a “pandemic.” Irwin tells us about the difference between “physical distancing” and “social distancing.” He explains why we want to be physically distant but remain socially together. You’ll learn more about pandemic modeling and projections. We investigate the importance of “contact tracing.” And, Irwin explains why we have to be careful when discussing “small” percentage changes.

    Discover more about the possibilities of a second and third wave of the outbreak. We explore why a rush back to open things is concerning. Irwin shares his thoughts on the death rate during the pandemic and why there might be severe undercounting. We also investigate statistics coming from other countries and if there’s any reason to not believe the reports.

    Lastly, we find out what the United States did wrong that lead to the mishandling of early preventative steps. We also explore what other countries have been doing right to flatten the curve. You’ll hear how policy evolves throughout a crisis and how the public should react to constant flipflopping of messaging. All that, plus, Irwin leaves us with a message of hope for the future.

    What is the point of debate when one side the argument is objectively true? There is none.

    That is, unless the incorrect arguer has the ability to influence the masses. When a relatively famous musician began spewing flat Earth views on social media, astrophysicist Neil deGrasse Tyson knew he had to jump in the ring and defend science with science.

    General belief systems aren't a threat, but it's important to combat incorrect and dangerous views when they have a chance of pervading greater society.

    NEIL DEGRASSE:

    Neil deGrasse Tyson was born and raised in New York City where he was educated in the public schools clear through his graduation from the Bronx High School of Science. Tyson went on to earn his BA in Physics from Harvard and his PhD in Astrophysics from Columbia. He is the first occupant of the Frederick P. Rose Directorship of the Hayden Planetarium. His professional research interests are broad, but include star formation, exploding stars, dwarf galaxies, and the structure of our Milky Way. Tyson obtains his data from the Hubble Space Telescope, as well as from telescopes in California, New Mexico, Arizona, and in the Andes Mountains of Chile.Tyson is the recipient of nine honorary doctorates and the NASA Distinguished Public Service Medal. His contributions to the public appreciation of the cosmos have been recognized by the International Astronomical Union in their official naming of asteroid 13123 Tyson.

    Tyson's new book is Letters From an Astrophysicist (2019).

    TRANSCRIPT:

    I don’t like debating people because in a debate what is the construct. It’s typically two people and there’s an audience and you debate some opposite sides of some issue. And then there’s a winner of the debate. And then everyone walks away reflecting on the winner. So who wins the debate? It’s often the person who’s charismatic, who’s maybe charming – that’s related to charisma of course. Who has a good way with words, good vocabulary. And you can have someone who doesn’t have any of that who is speaking objective truths who could lose a debate. So then what is the point of the debate of one of these points of view is objectively true. So I will not enter a debate where I have the objectively true side of an argument and the other person does not. That is something that should not be debated, does not belong in front of an audience getting debated. You want to debate something? Debate political policy of what to do in the face of climate change.

    Do you have carbon tax? Do you have solar panels? Do you subsidize them? Debate that. Don’t debate something that is or is not objectively true in this world. The B.o.B, the rapper, I have a video letter to him the transcript of which is in Letters from an Astrophysicist. That rose to that level of attention because he started saying I am using laws of math and physics to show Earth is flat. Those are fighting words. If you’re going to say using math and physics, that is an alarm to the geekiverse that we must rise up and counteract these forces from the dark side that are out there. So, the bat signal went up. I responded. What is the bat signal? Oh, sorry. In my Twitter stream there are people saying Neil, you’ve got to do something about B.o.B. Save him from himself. He’s saying Earth is flat. Then I first said who’s B.o.B? So I quickly looked him up. Oh, he’s a rap star. Okay.

    These are people who follow me and B.o.B in the Twitterverse. So what does that Venn diagram look like. How much overlap is there in the two Venn diagrams. In this slice, however narrow, they were pleading to me to do something and so I responded with a video letter. Just kind of putting him in his place.

    I think it’s important to combat people who are claiming that they are using math, science, evidence and physics behind their cause when, in fact, they either aren’t or they’re using it badly. That needs to be called out. Otherwise if you just have a belief system I don’t really care. We live in a country that protects free speech which usually also means free thought. If you want to think Earth is flat, go right ahead. But if you start influencing other people who have power over other people and you have no foundation and objective reality it can be dangerous. If you influence people or you yourself become someone who has influence over legislation, laws, rules by which we all abide in society. That’s an unhealthy situation for civilization to be in. If your personal belief system...

  • Neil deGrasse Tyson changes his mind about A.I.

    2:16

    He had the intuition that we could just shut down an A.I. whenever we felt like it, especially if at some point presented a threat to our survival.
    He changed his mind after listening to a Sam Harris podcast with Eliezer Yudkowsky. It's very rare for someone to admit their were wrong, my admiration for Neil deGrasse Tyson grew even more.

  • TIMELAPSE OF THE FUTURE: A Journey to the End of Time

    29:21

    Support my work on Patreon: | Get the soundtrack: | How's it all gonna end? This experience takes us on a journey to the end of time, trillions of years into the future, to discover what the fate of our planet and our universe may ultimately be.

    We start in 2019 and travel exponentially through time, witnessing the future of Earth, the death of the sun, the end of all stars, proton decay, zombie galaxies, possible future civilizations, exploding black holes, the effects of dark energy, alternate universes, the final fate of the cosmos - to name a few.

    This is a picture of the future as painted by modern science - a picture that will surely evolve over time as we dig for more clues to how our story will unfold. Much of the science is very recent - and new puzzle pieces are still waiting to be found.

    To me, this overhead view of time gives a profound perspective - that we are living inside the hot flash of the Big Bang, the perfect moment to soak in the sights and sounds of a universe in its glory days, before it all fades away. Although the end will eventually come, we have a practical infinity of time to play with if we play our cards right. The future may look bleak, but we have enormous potential as a species.

    Featuring the voices of David Attenborough, Craig Childs, Brian Cox, Neil deGrasse Tyson, Michelle Thaller, Lawrence Krauss, Michio Kaku, Mike Rowe, Phil Plait, Janna Levin, Stephen Hawking, Sean Carroll, Alex Filippenko, and Martin Rees.

  • Climate Change Facts & Myths with Neil deGrasse Tyson - Cosmic Queries

    53:38

    How did we save the ozone layer? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice break down the successful campaign to save the ozone layer with professor and atmospheric chemist Susan Soloman and director of research for the Institute of Governance and Sustabaility Stephen Andersen. What lessons can we learn to apply to the ongoing climate crisis?

    How do you save the world? We discuss their winning the Future of Life Award this week (details here) for their contributions to the 1987 Montreal Protocol. What was it? Is it the most successful treaty of our day? How did the ozone layer get depleted? What is a Chlorofluorocarbon or CFC? How do you convince people to get rid of what they have if you don’t have something for them to replace it with? We explore how industries and media were able to create a movement to help the cause. How do we create a sustainable civilization?

    How does the ozone layer work to protect us? Discover the different forms of oxygen and how they interact with UV rays from the sun. How much UV actually reaches the Earth’s surface? What are the actual effects of refrigerants and CFCs on the atmosphere? What’s HCFC22? Or HFC410A? Are we at the point of no return with runaway climate change? Do we have any new technology to reverse the change? We break down whether geoengineering Earth is a good idea and how to fix our dire energy infrastructure problem.

    Do all heroes wear capes? We take a moment to appreciate the work of climate scientists and the tireless work they’ve been doing against the clock. Would reducing the cost of greener alternatives be enough? What’s the most life-changing adaptation we will be forced to make in the near future? Is it true that 75% of all greenhouse gas emissions are created by just 100 companies? What does it mean to go carbon-neutral? What is the most likely cause for Earth becoming uninhabitable? How do you convince climate change deniers? What lessons can we learn and apply from the Montreal Protocol? All that, plus, Chuck announces the release of his new hit country album “My Daddy was a Solar Panel Installer.”

    Thanks to our Patrons Ryan Ogle, David Matthews, Colleen Magee-Uhlik, Ryan Atashkar, Cameron Q Myhre, Jordan Sisinni, and Mien for supporting us this week.

    ----------------------------------------------------------------------------------
    Carl Sagan believed humanity needed to become a multi-planet species as an insurance policy against the next huge catastrophe on Earth. Now, Elon Musk is working to see that mission through, starting with a colony of a million humans on Mars. Where will our species go next?

    Theoretical physicist Michio Kaku looks decades into the future and makes three bold predictions about human space travel, the potential of 'brain net', and our coming victory over cancer.

    [I]n the future, the word 'tumor' will disappear from the English language, says Kaku. We will have years of warning that there is a colony of cancer cells growing in our body. And our descendants will wonder: How could we fear cancer so much?
    ----------------------------------------------------------------------------------
    MICHIO KAKU:

    Dr. Michio Kaku is the co-founder of string field theory, and is one of the most widely recognized scientists in the world today. He has written 4 New York Times Best Sellers, is the science correspondent for CBS This Morning and has hosted numerous science specials for BBC-TV, the Discovery/Science Channel. His radio show broadcasts to 100 radio stations every week. Dr. Kaku holds the Henry Semat Chair and Professorship in theoretical physics at the City College of New York (CUNY), where he has taught for over 25 years. He has also been a visiting professor at the Institute for Advanced Study as well as New York University (NYU).

    Read Michio Kaku's latest book The Future of Humanity: Our Destiny in the Universe at
    ----------------------------------------------------------------------------------
    TRANSCRIPT:

    MICHIO KAKU: We are entering what I call the next golden era of space exploration. We have not just new energy and new financing and money coming from Silicon Valley, we also have a new vision emerging. For Elon Musk of SpaceX it's to create a multi-planet species. However, for Jeff Bezos of Amazon, he wants to make Earth into a park so that all the heavy industries, all the pollution, goes into outer space. And Jeff Bezos wants to set an Amazon-type delivery system connecting the earth to the moon. And so he wants to lift all the heavy industries off the planet Earth to make Earth a paradise and to put all the heavy industries in outer space.

    Now, I once talked to Carl Sagan and he said that because the earth is in the middle of a shooting gallery of asteroids and comets and meteors, it's inevitable that we will be hit with a planet buster. Something like what hit the dinosaurs, 65 million years ago, we need an insurance policy. Now, he was clear to say that we're not talking about moving the population of the earth into outer space—that costs too much money. And we have problems of our own on the earth like global warming. We have to deal with those problems on the earth not flee to outer space. But as an insurance policy, we have to make sure that humans become a two-planet species. These are the words of Carl Sagan.

    And now, of course, Elon Musk has revived this vision by talking about a multi-planet species. He wants to put up to a million colonists on the planet Mars, sent to Mars by his rockets financed by a combination of public and private funding, including fusion rockets, ramjet fusion rockets, including anti-matter rockets. Some of these rockets, of course, their technologies won't be available till the next 100 years. However, the laws of physics make it possible to send postage-stamp-size chips to the nearby stars. So think of a chip, perhaps this big, on a parachute and have thousands of them sent into outer space energized by perhaps 800 megawatts of laser power. By shooting this gigantic bank of laser energy into outer space, by energizing all these mini-parachutes you could then begin to accelerate them to about 20% the speed of light. This is with doable technology today. It's just a question of engineering. It's a question of political will and economics but there's no physics, there's no law of physics preventing you from shooting these chips to 20% the speed of light. That means Proxima Centauri, part of the Alpha Centauri triple star system, could be within the range of such a device. Now think about that. That means that within 20 years, after 20 years of launch, we might be able to have the first starship go to a nearby planet. And it turns out that Proxima Centauri B is an Earth-like planet that circles around the closest star to the planet Earth—what a coincidence. So it means that we've already staked out our first destination for visitation by an interstellar starship. And that...

  • Richard Terrile | The Universe as a Simulation

    20:38

    How do you know that we aren’t just figments of someones imagination? NASA scientist Richard Terrile ties together both science and religion in this talk and how there is a possibility that our existence is simply a simulation.

  • The Big Idea: Is Life a Simulation?

    3:10

    As a philosophy professor at NYU, David Chalmers focuses on the concept of consciousness: questions of what the mind perceives as reality. He asks: How do we know we're not in a simulation where everything is an illusion? How do we know we aren't living in a simulation -- a mastery of complex algorithms -- creating a cosmic artificial world all set up by our ancestors or some other intelligent being? These concepts sound very red pill-blue pill Neo in the Matrix.

    Hod Lipson is a professor of engineering at Columbia University. He specializes in robotics. He says that the simulation theory is controversial but it is technologically possible.

    Possible? Really? He says that artificial intelligence is progressing at an exponential rate. 40 years ago all we had was Pong. Now games are immersive and life-like.

    Billionaire and Space X founder Elon Musk believes that centuries from now humans will have the capability to create beyond what we can imagine. He shocked the tech world by putting the odds we're not in someone else's simulation at 1 in 1 billion. Musk says humans will either create simulations that are indistinguishable from reality or civilization will cease to exist.

    But Musk is wrong, according to Peter Morgan, the chief artificial intelligence officer with Ivy Data Science, a company specializing in AI education.

    He says there are ways to test the limits of our physical world, such as by measuring cosmic rays. he says that if we were living in a simulation, the energy distribution from the rays would be asymmetric. So far, good for us. He says everything lines up.

    Winslow Burleson, the director of the NYU-X lab at the College of Nursing, says that what the debate really boils down to is a fundamental question of humanity. Why are we here? He says you can't necessarily know if god exists or not, but you can take it on faith. He says that and whether we are in a simulation are very profound questions. He says he just tries to be the best person he can be, explore and discover, and foster that in other people.

    That is life as we know it.
