NEIL DEGRASSE TYSON

Continuing with our Let’s Make America Smart Again series, Neil deGrasse Tyson, comic co-host Chuck Nice, and astronomer David Helfand are here to sift through the data and help you stay scientifically literate in the misinformation age. David discusses the “absent curation” of daily data and how the creation of search engines was helpful but also created more intricate problems. You’ll hear about science browsers and filters, why science might be too successful, and David’s his top three tools you can use to sift through misinformation. David describes teaching at Quest University Canada, where he allowed students to “construct knowledge” instead of feeding them a constant stream of information. Discover more about the “reproducibility crisis” in the science community. Learn about the role that scientists play in the age of misinformation and about the many biases scientists can be exposed to – and persuaded by – during their research. Explore why the democratization of information is good overall but comes with baggage and responsibility. Dive into David’s book, A Survival Guide to the Misinformation Age: Scientific Habits of Mind. All that, plus, Neil and company answer fan-submitted Cosmic Queries about a variety of topics including the Dark Ages, dark matter, a global space agency, the correct definition of a fact, dealing with the anti-science culture, and using social media to confront alternative facts.

On this episode of StarTalk Radio, Neil deGrasse Tyson sits down with Anthony Daniels, the man behind one of the most iconic characters in film history – C-3PO. Anthony (as C-3PO) is the only person to appear in all nine Star Wars films spanning multiple decades and you’ll hear about his time involved in the biggest movie franchise on Earth. In-studio, Neil is joined by comic co-host Chuck Nice and robot ethicist Kate Darling, PhD, to explore C-3PO’s cultural impact and the rise of robotics in our society. Kate investigates “human-robot interaction from a social, legal, and ethical perspective” so she is just the person we want for this conversation. We start with a simple question – what makes C-3PO so likeable? Find out why C-3PO’s appeal stems directly from his humanity. Anthony tells us why he wasn’t really a fan of science fiction before he took the part of C-3PO. You’ll learn about the development of C-3PO and why his subtle asymmetrical design brings his “humanity” to the forefront. We explore how robots have evolved since the beginning of robotics. We breakdown the differences between androids and robots. Find out more about the “uncanny valley.” We ponder the concept of the “soul.” Kate enlightens us to what our interactions with robots tell us about our personalities. Can you create strong bonds with a robot? Should our laws protect robots? We investigate how film’s portrayal of artificial intelligence has created unnecessary fear of robotic advancements. We also explore the flaws still found in today’s cutting edge technology. Lastly, we ponder how robots will be introduced into more shared spaces like grocery stores, cafes, etc. All that, plus, Kate tells us what the biggest dilemma will be as robotics continue to advance.

Have you ever wondered why the sky is blue? Neil deGrasse Tyson is here to help you answer that question alongside comic co-host Chuck Nice. And, you’re about to find out why the answer is easy to understand, but not that simple. You’ll learn how the white light from the sun interacts with the atmosphere through a process called “Rayleigh scattering” that makes the sky blue. Neil tells us why the sky turns different shades as the day goes on, and why the sunset changes from blue to amber. Discover why the reason we have a blue sky is the same reason you can’t see stars during the daytime. And, how this lead to the discovery of the operational definition of where the atmosphere ends and space begins. Neil explains why he thinks space should be defined by gravity and not by the circumstances of our atmosphere. Lastly, Neil gives us a lesson on the frailty of our atmosphere and our delicate place among the stars.

Happy Earth Day! Neil deGrasse Tyson and comic co-host Chuck Nice are here to help you celebrate Earth Day 2020 by giving you a cosmic perspective. How did we come to have a cosmic perspective about humanity’s place in the universe? According to Neil, a lot of this new way of thinking can be traced back to one iconic photo – Earthrise. Neil shares why, before 1962, we weren’t really thinking about Earth as a whole. You’ll learn about the importance of Silent Spring, an environmental science book by Rachel Carson that alerted us to the adverse effects caused by pesticides. Then, we reminisce on the iconic photo “Earthrise” taken by astronauts aboard Apollo 8 that showed “Earth for the first time.” Find out why, even though 1968 was a year of great loss, it sparked a great amount of environmental change. We discuss the establishment of NOAA, the EPA, and Doctors Without Borders. We also discuss our new awareness about pollution. Lastly, Neil shares why this global way of thinking has been entrenched in our society during this coronavirus pandemic. =================================== 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.

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. This episode originally aired February 24, 2020.

Shutting down flat Earthers, Neil deGrasse Tyson style New videos DAILY: https://bigth.ink/youtube Join Big Think Edge for exclusive videos: https://bigth.ink/Edge ---------------------------------------------------------------------------------- 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... To read the full transcript, go to https://bigthink.com/videos/neil-degrasse-tyson-flat-earth
