NEIL DEGRASSE TYSON

How can quantum physics spoil food? You know how food usually spoils, but quantum physics?! On this StarTalk explainer, Neil deGrasse Tyson and comic co-host Chuck Nice are here to fill you in on the physics of what’s going on in your fridge. First, we need to know how most food commonly spoils. Neil tells us about the “normal” way food goes bad which involves microbes, bacteria, and temperature. We explore unpasteurized milk vs. pasteurized milk. Then, Neil explains how quantum physics can spoil your food (after a really long time). We discuss “quantum tunneling.” You’ll learn about the behavior of molecules and their continual quest to be “happy.” All that, plus, find out if there’s anything you can do to stop this quantum phenomena.

In this StarTalk video, we’re talking about nothing. Not in the Seinfeldian sense, but in the science sense. What is nothing? Neil explains how our usual definition of something being “nothing” is dictated by our senses. What if you wanted to get all the way down to true nothing? Well, even when there’s nothing, there’s air molecules, and a lot of them. So, what happens when you take out the air molecules? Find out just how much air molecules permeate in our environment, in our solar system, in interstellar space, and intergalactic space. Then, just when you think you truly have nothing, you’ll hear how quantum physics comes into play. Discover more about virtual particles and why the best “nothing” you could have is filled with virtual particles. All that, plus, we debate if being able to describe something that is nothing makes it something.

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.

How much of the galaxy have we actually searched for extraterrestrial life? Neil deGrasse Tyson explores just how little we've looked at with Jill Tarter, astronomer and former director of the SETI Institute. Jill makes an astounding comparison of how much we've searched the galaxy for extraterrestrial life to searching for fish in the ocean that will put things in perspective. Then, Neil is joined by comic co-host Michael Ian Black and Seth Shostak, senior astronomer at the SETI Institute, to ponder what humanity's role is if we find out we're alone in the universe. Lastly, we answer a couple Cosmic Queries on discovering E.T. signals from life long gone and the process behind sharing signals with the public when we finally receive them.

On this episode of StarTalk Chat Room, we’re taking a deep dive into episodes seven and eight of Cosmos: Possible Worlds. Given that we are currently living in the “Corona-verse,” Neil deGrasse Tyson is joined by video call by his intrepid comic co-host Chuck Nice. We start with episode seven, “The Search for Intelligent Life on Earth.” You’ll learn about the Five hundred meter Aperture Spherical Telescope (FAST) located in China which has a 500m diameter disc, making it the largest radio telescope in the world. Neil tells us what it was like to film at the telescope itself. Find out why radio waves are the most ideal form of communication across the galaxy. Neil and Chuck ponder if aliens were trying to contact us via radio waves before we invented a way to detect them. You’ll hear from executive producer Jason Clark to talk about one of his favorite moments from the series. Discover more about the writing process behind Cosmos: Possible Worlds. Then, we explore the intelligent life on Earth that you might have overlooked: bees. Neil explains how you can get a cosmic perspective studying something so close to home. After the break, we welcome long-time friend of StarTalk, Madame Saturn herself, Carolyn Porco. Episode eight, titled “The Sacrifice of Cassini,” explores the journey of the Cassini space probe’s mission to explore Saturn and its moons. Carolyn was the leader of the Cassini Imaging Team and she takes us inside the control room on one of the most epic journeys of our time. You’ll hear about the overlap Cassini had with the Voyager mission, including Carolyn’s own involvement. Discover more about the famous “Pale Blue Dot” photo. We look at Carl Sagan’s influence on inspiring the public with scientific information and how Carolyn continued that initiative with Cassini. Lastly, we ponder what the next mission will be and what tantalizing information could be out there awaiting our discovery.
