  • Neil deGrasse Tyson Explains Alien Visits, UFOs, and Other Conspiracies

    19:20

    Are alien spacecrafts here on earth? In this explainer video, Neil deGrasse Tyson and comic co-host Chuck Nice discuss the existence of aliens on earth and what the scientific community thinks of it.

    Do conspiracy theories like UFOs hold any truth or validity? Or is this obsession with aliens just fueled by the movies? Find out what T-Rex, blackholes, and the brothers Grimm have in common. We also debate whether imaginings of evil aliens are just based on how we humans treat each other. Are the people being visited by aliens always the ones in danger?

    What do aliens look like? Learn why we often portray aliens as being vertebrate. Would advanced aliens capable of space travel even care about us? You’ll learn how alien sightings have changed over the years with the innovations in photographic technology. We explore the leaps many people take when they discover things in the night sky. Are human senses even trustworthy without further evidence? Is the government competent enough to keep this a secret? All that and more on another StarTalk explainer!

  • Could Cosmic Interloper Be An Alien Spacecraft? Neil DeGrasse Tyson Isn’t Sure | Mach | NBC News

    4:09

    Scientists have been puzzling over a mysterious object in space ever since it was first spotted tumbling past the sun in late 2017. Now a pair of Harvard researchers are raising the possibility that it’s an alien spacecraft. As they say in a paper to be published Nov. 12 in The Astrophysical Journal Letters, the object may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization.

  • Neil deGrasse Tyson: Where Are the Aliens?

    3:54

    If there is alien life in the galaxy, where are they? Have they already visited Earth? In this video from Business Insider and StarTalk Radio, astrophysicist Neil deGrasse Tyson speculates on what might happen if aliens do visit Earth, and what they might think of us, our scientific achievements and our early adventures in space. Neil also discusses what Stephen Hawking’s fear of aliens really says about how we have treated less advanced civilizations in the past.

    3 scientists school flat Earthers on the evidence
    Watch the newest video from Big Think:
    Learn skills from the world's top minds at Big Think Edge:
    ----------------------------------------------------------------------------------
    Despite centuries of evidence proving otherwise, there is an alarming number of people around the world who genuinely believe that the earth is flat. Bill Nye The Science Guy, NASA astronomer Michelle Thaller, and Neil deGrasse Tyson strongly disagree.

    From simple experiments like standing at a seashore or looking through a telescope at other planets, to reading about navigation or viewing photos of Earth taken from space, the scientists share several ways that flat Earthers can see the truth for themselves.

    Tyson explains why this trend doesn't qualify as a scientific debate and why it is actually dangerous for people to believe and, even worse, pass on these objectively false ideas.
    ----------------------------------------------------------------------------------
    NEIL DEGRASSE TYSON:

    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.
    ----------------------------------------------------------------------------------
    BILL NYE:

    Bill Nye, scientist, engineer, comedian, author, and inventor, is a man with a mission: to help foster a scientifically literate society, to help people everywhere understand and appreciate the science that makes our world work. Making science entertaining and accessible is something Bill has been doing most of his life.

    In Seattle Nye began to combine his love of science with his flair for comedy, when he won the Steve Martin look-alike contest and developed dual careers as an engineer by day and a stand-up comic by night. Nye then quit his day engineering day job and made the transition to a night job as a comedy writer and performer on Seattle’s home-grown ensemble comedy show “Almost Live.” This is where “Bill Nye the Science Guy®” was born. The show appeared before Saturday Night Live and later on Comedy Central, originating at KING-TV, Seattle’s NBC affiliate.

    Nye is the host of three currently-running television series. “The 100 Greatest Discoveries” airs on the Science Channel. “The Eyes of Nye” airs on PBS stations across the country.
    Bill’s latest project is hosting a show on Planet Green called “Stuff Happens.” It’s about environmentally responsible choices that consumers can make as they go about their day and their shopping. Also, you’ll see Nye in his good-natured rivalry with his neighbor Ed Begley. They compete to see who can save the most energy and produce the smallest carbon footprint. Nye has 4,000 watts of solar power and a solar-boosted hot water system. There’s also the low water use garden and underground watering system. It’s fun for him; he’s an engineer with an energy conservation hobby.
    ----------------------------------------------------------------------------------
    MICHELLE THALLER:

    Dr. Michelle Thaller is an astronomer who studies binary stars and the life cycles of stars. She is Assistant Director of Science Communication at NASA. She went to college at Harvard University, completed a post-doctoral research fellowship at the California Institute of Technology (Caltech) in Pasadena, Calif. then started working for the Jet Propulsion Laboratory's (JPL) Spitzer Space Telescope. After a hugely successful mission, she moved on to NASA's Goddard Space Flight Center (GSFC), in the Washington D.C. area. In her off-hours often puts on about 30lbs of Elizabethan garb and performs intricate Renaissance dances. For more information, visit
    ----------------------------------------------------------------------------------
    TRANSCRIPT:

    BILL NYE: Is the earth flat or round? It's round, okay. Now, let's see. How do we go about proving that?

    MICHELLE THALLER: That's a hard thing for me to even start talking about because there are so many proofs that the earth is round it's difficult...

  • Searching for Aliens, with Neil deGrasse Tyson

    5:09

    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.

    This segment originally appeared in our 4x Emmy-nominated StarTalk TV show on the National Geographic Channel, and in the StarTalk Radio podcast, The Search for Extraterrestrial Intelligence, with Jill Tarter, on June 2, 2017.

    Astrophysicist Neil deGrasse Tyson joins us to talk about one of our favorite subjects: space.

    In the three-chaptered video, Tyson speaks about the search for alien life inside and outside of the Goldilocks Zone, why the term dark matter should really be called dark gravity, and how the rotation of the Earth may have been the deciding factor in a football game.

    These fascinating space facts, as well as others shared in Tyson's books, make it easier for everyone to grasp complex ideas that are literally out of this world.

    NEIL DEGRASSE TYSON:

    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 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 Astrophysics for People in a Hurry, you can check it at
    ----------------------------------------------------------------------------------
    TRANSCRIPT:

    NEIL DEGRASSE TYSON: When we think of places you might find life we typically think of the Goldilocks Zone around the star where water would be liquid in its natural state. And if you get a little too close to the star, heat would evaporate the water and you don't have it anymore. It's gone. Too far away it would freeze and neither of those states of H2O are useful to life as we know it. We need liquid water. So you can establish this Green Zone, this habitable zone, this Goldilocks Zone, where if you find a planet orbiting there hey, good chance it could have liquid water. Let's look there first for life as we know it.

    Now it turns out that this source of heat, of course is traceable to the sun and if you go farther out everything water should be frozen, all other things being equal. But Europa, a moon of Jupiter sitting well outside of the Goldilocks Zone is kept warm not from energy sources traceable to the Sun, but from what we call the tidal forces of Jupiter itself. So, Jupiter and surrounding moons are actually pumping energy into Europa. And how does it do that? As Europa orbits Jupiter its shape changes. It's not fundamentally different from tides rising and falling on Earth. The shape of the water system of the Earth is responding to tidal forces of the moon. And when you do that to a solid object, the solid object is stressing. And because of this, a consequence of this is that you are pumping energy into the object. It is no different from when you say to anyone who's familiar with racquet sports, indoor racquet sports. It could be racquetball or squash. You say let's arm up the ball before we start playing.

    You want to hit it around a few times. You are literally warming up the ball. It's not just simply let's get loose. You are literally warming up the ball. How? You are distorting it every time you smack it and then the resilience of the ball pops it back into shape and every time you do that, every smack, you're pumping energy into the ball. It's not fundamentally different from what's going on in orbit around Jupiter. So, you have this frozen world, Europa, completely frozen on its surface but you look at the surface and there are cracks in the ice. There are ridges in the ice where there's a crack and it shifted and then refroze. So this ridge has a discontinuity in the crack and it continues in another place. So what this tells you is that Europe cannot be completely frozen because if it were nothing would be moving. You look at the surface of Europa, the frozen surface, there are like ice chunks that are shifted and refrozen and shifted again. It looks just like if you fly over the Arctic Ocean.

    Fly over the Arctic Ocean in the winter...

    Shutting down flat Earthers, Neil deGrasse Tyson style

    ----------------------------------------------------------------------------------
    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...
