John Parnell John Parnell 6 months ago Can't believe I never watched this one. Loved it. I'm so glad that one of the smartest people in the world has a sense of humor. Always enjoyable. 5 JwellsMedia Inc. JwellsMedia Inc. 1 year ago I liked the conversation about intelligence. I would add, I would think that intelligence is secondary feature of life unlike locomotion and eyesight. For example, maybe the reason why intelligence isn’t common in the record of life may be because it’s not needed for life forms to perform the basic functions needed for survival. You think about technology. There was a point when your cell phone only made and received phone calls, and that was fine for the time because your device did what was intended of it at a basic level. You fast-forward to today, phones can order Sushi, direct you in traffic, entertain us when we’re bored, and even connect us in more ways than that was possible 30 years ago. All of these added features of modern cell phones (literally called smart phones) are secondary features that go beyond the primary functions for which the cellular phone was originally intended for. I always believed that intelligence played a similar role in the evolution of life. Intelligence is not a guaranteed upgraded feature of life, but it is a later feature of an advanced life form. Like I think it’s safe to say that mammals and birds are slightly smarter overall than the average non-avian dinosaur from 65 million years ago, and that dinosaurs are smarter than what proceeded them. So intelligence, even on dog-like level seems like a late game feature of life. 12 Scottys Glass 101 Scottys Glass 101 4 months ago I wanted to ask why the fusion of iron in stars is endothermic. I thought I'd look it up on Wikipedia but I got lost and ended up at pulse oximetry. There should be a "Neil" version of Alexa. 4 1 IN A BILLION.. unfortunately.. predetermined 1 IN A BILLION.. unfortunately.. predetermined 1 year ago I believe Neil is correct about intelligence but one question I would like to ask him is,why do us humans individually believe inside each and every one of us that we are the one, the special one and that there's something we are here to do besides live like help change the world for the better. Duran Sekona Duran Sekona 2 months ago He spoke to Disney's "top people", mentions the multiverse, Disney acquires Marvel Cinematic Universe, and releases Dr. Strange and the multiverse of madness. I have no idea what all this means. I'm gonna climb into my hyperbolic time chamber and study quantum mechanics. 2 Daniel Daniel 5 months ago Neil is awesome…his explanations are so cool. 10 Dasean Clark Dasean Clark 3 years ago that line, "Physicists are atoms' way of admiring themselves" blew my mind and threw me into a laughing fit lol. 11 ganesan santhanam ganesan santhanam 1 year ago robert krulwich is one of entertaining host I have ever seen. He is able to keep jolly and when it comes to Neil is teasing him or bickering is awesome 1 Rikki Furey Rikki Furey 1 year ago love your books neil and i love your passion so do not worry if u r thinking u r shouting it's not the same as shouting in anger it's pure passion and i love it keep it up and thank u i have learnt a lot from your books and L.Krauss and Richard Dawkins i wish there was more people like u and richard dawkins there r to many idiots these days with conspiracy ideas that r indoctrinating more and more people it's a real shame to all of us as a species. elena yamaguchi elena yamaguchi 1 year ago I love Neil Tyson way of thinking, letting others to learn the reality of our world , because we've just taught what to do beleive,..we live in a controlled or hypnotic by powerrful person in this world. Kevin McIntyre Kevin McIntyre 1 year ago Damn, my mind was blown throughout but that last part about the uneven application of quantum mechanics to the physical product of the Big Bang lending credibility to the Multiverse Theory was a hell of a way to close it out. I'm thankful to have access to this kind of knowledge without having to pay anything or enter a classroom. 1 Cranston Coleman Cranston Coleman 4 months ago My 1st YouTube seminar with Neil degrasse Tyson in my 61 year of life on earth. Hopefully there will be more of them 10 EmeraldView EmeraldView 3 years ago I love the down to earth way this guy explains things. 19 Kurt Tuchscherer Kurt Tuchscherer 7 months ago In the 70's I read all the books by Carlos Castaneda and the teachings of Don Juan. Back then the thought of multi verses were considered the ramblings of a mind distorted by psychotropic drugs. It amazes now how science is lining up with the beliefs held by the Yaqui Indians for centuries 11 Allan Hytowitz Allan Hytowitz 11 months ago Quandaries is the correct spelling But Neil is brilliant and this is worth multiple viewings. United Space Pirates United Space Pirates 1 year ago (edited) Dark energy is an illusion caused by the gravitational distortion caused by the gravitational fields of distant galaxies. Gravity from distant galaxies has a redshift effect on the frequency of light they emit in the same way that gravity can bend the path of light. Hence no cosmic acceleration, no dark energy, no un accounted for dark matter, no big bang, this universe is eternal, no beginning or ending. Cosmic background microwaves are just distant galaxies who's light has been gravitationally distorted beyond your visible spectrum. Galaxies exchange and recycle energy and birth new stars out of old dead ones. Jonathan Berman Jonathan Berman 7 months ago (edited) Interviewer asks Neil DeGrasse Tyson, "Why would a person conjure up a multiverse where the laws of physics are different?" I think that's a good question, as someone born in one religion gains perspective studying other religions, we gain perspective studying other universes... Btw, it was clear Neil hated this guy, he interrupted him non stop and was kind of a petty dick with him. I think Neil came off pedantic and rude though. https://www.youtube.com/watch?v=rYzBxo3hbYQ Cindy Riehm Cindy Riehm 4 months ago Thank you!!! I knew we were NOT special. Which brings up our view of us Being the only "beings" in the extended Universe as nuts. Ill concieved. Jay N Jay N 1 year ago What I love most about Neil is his brutal honesty about what he does'nt know and his exactness for what he does know. And of course his ability to communicate both these things. 15 Bill McGubbins Bill McGubbins 1 year ago (edited) I'm all for science and the advancement of knowledge. However, the way scientists completely dismiss the possibility of black holes being basically a natural wormhole really really bothers me. In fact, a LOT of cosmologists have what seems to me as a VERY arrogant attitude toward their UN-proven theories. Especially when it comes to black holes. We have absolutely ZERO experience with ANY black hole. They're theorized to exist, but the way they're discussed leads people to believe that we've not only seen plenty of black holes, but done so IN PERSON, and talk about their theories as if they've already been observed and set in factual stone. But the truth is we've only observed what we THINK may be black holes but until we actually see one or create one in a lab, we don't actually KNOW anything about a black hole. They exist solely in the theories and minds of the scientific religion. So when ol' Degrasse Tyson there says "we now KNOW that our information stays intact after entering black holes, and black holes eventually spit back out everything it pulls in. As if someone SAW it happen... It really bugs me!! As though black holes are well understood!! NOT the case! Humankind has no evidence of what might happen because NOBODY has ever seen one before. Does anyone know the intrinsic properties of unicorns? Would you believe someone who claimed they were a unicorn expert? Would you believe someone who said they'd not only seen unicorns but then went on to tell you that they "know" unicorns can't be the color yellow because all the people painting them don't like that idea? Well?? It's crazy! Moh'd Sadiq Alzikry Moh'd Sadiq Alzikry 4 years ago "The physicist is the atoms way of admiring themselves". Liked that line. It fitted perfectly. 61 ganesan santhanam ganesan santhanam 1 year ago Neil keeping it real when it comes to science😂....I love how passionately he explains .. teachers should act like Neil when they teaching that's enough to get generation of rationally and morally equipped adults who will be less tolerant to religious hokum and they will keep it real from then on to lead to better species. We are one percent gene mutation away to becoming telepathic humans 😂😂The answer is Neil level science love 22 Jason Drennen Jason Drennen 1 year ago Wow for the first time since Carl Sagan you have blown my mind. All the things I thought about in life and understanding. I have never thought about the fact that we can look back in time just by looking far away. So in reality we are reliving the past through the lenses of telescopes. So when we look at each other we are also looking at the past in nano seconds but we are. Which means it's plausible to look back in time only if we had a satellite at the right distance with powerful enough optics but only if we are sitting on that satellite. Because the time it would take for the information to get back here would equal out to the time it takes to see it. But what if there was a way to bounce light to create that same distance without even leaving the area? How precise would a set of mirrors have to be to set it up now then rewatch the set up two months from now? Wonder if that's why when you line mirrors directly up you see nothing? Wonder if it's because you're just not looking into them long enough? Amazing 6 Waya Weayaya Waya Weayaya 8 months ago I love how Neil DeGrasse Tyson brakes everything down for everyone to learn..Thank you! 43 Linda Mac Linda Mac 1 year ago Absolutely love you Neil, thank you for being you, your wry sense of humor and of course, your scientific intellect! Have a blessed day ALL! 3 Joel Louzy Joel Louzy 1 year ago (edited) The Steel phatom at Kennywood PA exploits one of the worlds largest drop because after the first incline the second takes advantage of the topography on its second drop that is well below the starting elevation. PS: it is an interesting coaster because it gives up alot of its energy after the forst drop going into tje second. Reserving enough kinetic energy after the second drop to get back home. It was uodated since i was a kid. Now it sacrficed g's and banging the hell out of your head at the end for a less exciting ride. stuntard stuntard 3 years ago What a great interview, really enjoyed it👍 24 Jon "maddog" Hall Jon "maddog" Hall 9 months ago (edited) If someone's toddler, through a change in their genes, was born so intelligent that they could derive Calculus by age two, and write seven masterpieces of music, etc....would they let their parents (or anyone else) know how intelligent they are? Would their parents, no matter how loving, try to kill the child because of the child's intelligence due to fear? Mr. Ed, the talking horse (a TV show of the early days) only let one person, Wilbur, know he could talk. 11 gerkenator gerkenator 1 year ago I really like Neil DeGrasse Tyson. Super intelligent guy that somehow is incredibly humble. He is gifted in taking something complex and bringing down to a level that someone (me) of lesser intelligence can understand it. Pretty amazing. 22 Rob Stimson Rob Stimson 3 months ago The two of these characters, together, are very fun. Dion Zoe Dion Zoe 1 year ago This man is over the top inspiring! I love him! Rage vs Raid Rage vs Raid 4 months ago Imagine just imagine if Neil isn't as smart as he thinks he is. 2 Thomas H Sears Thomas H Sears 1 year ago The problem with the "why" question is that it is actually two distinct questions. One asks for a cause, and is answerable an "how" a thing came to be. The other asks for a goal, and is not answerable with out a plan and a knowledge of it. "Why did the toronado happen?" Because the interaction between two air masses resulted in an intense, localized vortex to form and propagate. "Why did the tornado happen?" Because the air resented the existence of the trailer park. Or it was a punishment from an angry god. Or the Vogons needed a clear space to fly through. Or ... well, I don't know, and I don't believe there is an answer to that "why" question. 6 GOP Яepublican Caliphate of Texas GOP Яepublican Caliphate of Texas 1 year ago I wonder if there's some way to bounce some kind of particle beam off of distant photons, as a way of photographing images from far in front of your lens, sort of a "virtual lens" but the main limitation is again the speed of light 3 Bentley's Backwoods Bushcraft Bentley's Backwoods Bushcraft 1 year ago Neil is just plain Awesome. He, and those like him, should be the Rock Stars of our world. (by the way was a Sliders episode, if you remember that tv series) 6 Happy Accident Productions Happy Accident Productions 7 months ago This is what critics of Mr. Wolff and worker cooperatives don’t seem to understand. He’s not saying “co-ops ARE socialism.” He’s saying that worker cooperatives should be at the center of the shift from capitalism to socialism. Uniting the proletariat from within their workplaces is key. It will form the foundation for revolution (political, social, and otherwise). 1 Jose Joyette Jose Joyette 1 year ago (edited) How fascinating when I thought that they were both challenging each other and that one was the favourite; whereas if you kept watching, you see that they are working with the minus and positive. A few times where there were a sense of fear in terms of “If they know what you were thinking about like speech bubble,” then that’s inferior. I can honestly say, there’s a fight of infinite analysis to exist for more knowledge of out of space, and inside the sea and this seminar shows that even if you are on your own in this planet, there’s still hope for a mass of intelligence and yet humility of a drop of a carbonated bubble. I know I’m very self depricative as a person but to engage with society today is going to be very difficult. So teachers like you are needed. 4 Monipulator3216 Monipulator3216 11 months ago So, if the Universe was a singularity at the beginning (I support the Big Bang Theory), was it a black hole, since it had infinite density? Has anybody ever observed anti-matter and matter annihilate each other? If so, how did it not kill them if it's one of the most energy intense reactions in the universe? 4 TrueChimera TrueChimera 2 years ago This man is everything I respect. 22 Dr. Pepper Dr. Pepper 1 year ago I've got to say he's wrong about the heighest point on Earth. Elevation is measured from the surface of the oblate spheriod that is our Earth. So surface=sea level, that is what we measure height or the highest point from, not the center point in the earth. He kind of changed some definitions so he could make sure you know he's very smart in knowing about equatorial bulge. I guess it sounded better than just saying 'hey the earth's shape is an oblate spheroid, betchya didn't know that', but still it's not correct without him changing common defintitions. Elijah Love Elijah Love 2 years ago Damn, something that always grinds my gears - When an established organization posts a video with audience questions and doesn't provide captions for the barely audible question being asked. 76 Jonathan Ryals Jonathan Ryals 1 year ago Actually 👓 , the Earth doesn't spin exactly once per day... You must factor in that we go around the sun as well, which adds an extra "spin" over the course of a year, so each day the Earth spins approximately 365/366 times. Think, as the Earth moves around it's orbit, each day the actual direction of the sun changes by ~1/365th (depending on where we are, in reality the earth speeds up when nearer the sun, but the general principle still holds). 2 Daemon Thorn Daemon Thorn 3 months ago 1:01:57 It's not just the rarity of intelligence, itself, that needs to be considered. But also the type of body that this intelligence inhabits, as well. Think about it. If a species has intelligence that is equal to, or greater than, our own, but it has a body like a sea cucumber or a dolphin, then it would never develop a technological civilization because it would not have appendages that would enable it to manipulate it's environment very finely, like we do with our fingers and hands. And then you have to go even one step further in the biological lottery. They would have to be a terrestrial species. Or, at least, mostly terrestrial. They would not be able to be an aquatic species. They wont be able to discover fire, and the smelting and forging of metals, or the development of electronics, underwater. It's just not going to happen. I never see anyone mention this stuff, when discussing the possible rarity of intelligence in the universe. Intelligence is just one part of the equation. YaBoiSkinnyPenis YaBoiSkinnyPenis 7 months ago I definitely could of used Neil as my physics professor in college. Dropped the class cause I'm an idiot but I feel like with him teaching me... I still would of failed, but at least I would of failed with some what of an understanding 😂 4 Horace Morgan Horace Morgan 1 year ago A brilliant man! William Vickers William Vickers 4 months ago Could someone shed light of how much of this has now changed almost 10 years on? i remember reading somewhere that the amount of 'dark matter' is much more than the 6x regular matter that Tyson states here Hingle McCringleberry Hingle McCringleberry 8 years ago I enjoy how this interview went over the creation of the universe in extreme depth and yet there is an extreme lack of intelligent design gibberish in the comment section. It seems in the presence of detailed observation and thought process there is a profound lack of intelligent design. 32 Michael Gauthier Michael Gauthier 7 months ago The problem with looking in the universe for intelligence as we define it is that we defined it. jeremykass87 jeremykass87 1 year ago This is one of the most contentious intellectual explorations and series of thought experiments imaginable lol Has an almost debate theme where Neil is called on to answer the foundational quandaries of human thought and defend the very foundations of science and the other gentleman almost acts a moderator representing the historical misunderstandings of the general populace. Has alot of life for what should have been a severely droll affair. Having said all that, the multiverse theory is nearly indefensible as a scientific theory as its presupposes its own inability to be concretely proven, at least to my understanding 1 Man in the Park Man in the Park 1 year ago After listening to them talk about evolution, I now see how we have come from chimpanzees. It now makes sense how dumb we humans really are. Anil Heendeniya Anil Heendeniya 4 months ago Other than the poster misspelling "Quandaries" this was an excellent discussion, as expected from Dr. Tyson. 2 Raouf Lakehal Raouf Lakehal 4 months ago “It’s a point of view thing, I think” 3:58. The host maybe didn’t know it but he was right. Physics is about the perspective of the observer. Peter Smafield Peter Smafield 2 years ago There’s a book I’d like to recommend: Lies My Teacher Told Me (Everything Your American History Textbook) by James W Loewen. I’ve had the book for a while maybe six months maybe even longer and I’ve only gotten to page 15 so I have a lot of historical lies to go through although I know some of those lies already. Present Woodrow Wilson led America through the first world war but he tried adamantly not to bring America into World War I. 7 Benjamin Stubblefield Benjamin Stubblefield 3 months ago Remember your 1st Fox special? That got me interested in science for the 1st time. I hated science in high school! I liked Archaeology in the 60’s and 70’s. I have only been interested in science actively since December 2019. Robert Auriemma Robert Auriemma 11 months ago Fascinating discussion with an amazing Astrophysicist/Educator and a good natured and humble interviewer. 6 Jabberkong Jabberkong 4 months ago Physicists are the way atoms admire themselves. paraphrasing. That was great. 1 Acerbic Atheist Acerbic Atheist 1 year ago (edited) I agree with Dr.N.deG.Tyson about the use, or preferably lack thereof, of philosopho-jargon e.g."Epistemology", to name but one. I'm biased, though, being a hands-on empirical pure research biologist... who tries to stay abreast of the other fields of science because it makes me a better all-round scientist and teacher. And I love it too, of course! 👌😈👍 Science; it works... bitches! 🤣 Dr.Dawkins, what a great guy... and a great teacher, biochemist, writer, and science communicator no matter what Dr.T. might happen to think, which is an altogether different and less than entirely pleasant story, sadly. Oh yes, I nearly forgot to mention it, and I procrastinated for ages... but I am biting the bullet by the horn... and asserting that I have found Dr.T in error! IKR?! SHOCKER!! 📺🤔🤔🤔😳😬😈❗ It's not a major point, but it's there, so... That symmetry-breaking that leaves behind the entire amount of warm(hot, even!) baryonic matter that interacts with electromagnetism as well as gravity, and the two nuclear forces, it's even smaller a little bit left over than Dr.T says, at 1 part in 100,000,000; I'm almost entirely certain that it's 1 in 1,000,000,000 rather than only 1 in 100,000,000... but I am, naturally, prepared for the eventuality that I am mistaken... but I don't think that I am! ⚡⚡⚡✨😈👍🚬❗ Indeed, I'm going to find out sharpish, because it'll do my ego a power of good to find out that I have, in some small way, had a tiny victory over Dr.T! I wanted to be an astronaut; not American enough, plus not a pilot. Then I fancied astronomy or astrophysics, but not mathematical enough. Medicine? Tried it; not dedicated enough. Settled on the biology of cells and microbial ecology/biotechnology...in the time of the elucidation of the PCR technique! Yes I'm old, I've got over it, so so can you! 🦠🦠🦠❗ Running the show for 3.5 billion years at least! 🦠😈👍❤️ Always Learning Everyday Always Learning Everyday 1 year ago I don’t think most people realize that everything we know has come from the universe. If you open your perception you’ll see we are still apart of its cosmic structure and always will be, either in the form of energy or matter! That’s true faith! Tyler WantsToBeACreator Tyler WantsToBeACreator 3 years ago It’s amazing that he’ll probably go into science text books as a major scientist of our time(: 22 James Ramos James Ramos 1 year ago (edited) Could I say that one million centuries ago the Earth was a star 🌟? And, if Saturn is the most gaseous and least dense of the 8 planets could a space craft travel right through the middle of it without being destroyed in the process? RayneR RayneR 6 years ago Imagine there are 17 civilizations in our galaxy. 10 of which are on our level or maybe have colonized a few planets in their Star System. 4 of which have colonized more than one Solar System and 3 have whole empires through hundreds of solar Systems. Now Imagine there are 17 people in the Sahara desert put in random places around it. 10 are walking. 4 have bikes and 3 have helicopters. How much time do you think it will take for them to find each other by just moving around? And Just so you understand the Sahara Desert is as wide as the distance between PAris and Astana ... thats in Kazakhstan. 8 PATRICK HICKMAN PATRICK HICKMAN 6 months ago hypnosis: the induction of a state of consciousness in which a person apparently loses the power of voluntary action and is highly responsive to suggestion or direction. Its use in therapy, typically to recover suppressed memories or to allow modification of behavior by suggestion, has been revived but is still controversial. this is what ballsplainers have instead of physics, because on a ball you can't have vertical and horizontal, and you can't fly beyond the atmosphere because of newton's 3rd law........... but I am here to tell you that facts are absolutely not acceptable by ballosophers 2 Lucie Shores-McCommon Lucie Shores-McCommon 1 year ago It has been suggested that if the universe could send us a definitive message it would be “You are loved”... this means there is attraction in the essence of the stuff of the universe whose purpose is to create life and to evolve in every way possible in perpetuity. GO GETTA GO GETTA 10 months ago Both are great, very clear understanding of the true unknown. 9 Yuda M. Yuda M. 1 year ago Superstar Neil, so smart and funny! 2 Jaydapp Jaydapp 4 months ago I've heard that if Earth were scaled to the size of a cue ball that it would be smoother than the cue ball. Pretty crazy to think about. 11 Xuvial Xuvial 5 years ago (edited) I could listen to Neil all day. He explains everything SO well without hesitation, his thoughts and intelligence just flow freely. 60 sarah cooper sarah cooper 1 year ago 1/2 hour in and I am wondering if the tie was supplied by the studio. Such clarity and enthusiasm is great. 2 The Second Initiate The Second Initiate 1 year ago This whole conversation avoids the vacuum catastrophe with Neil's false premise that the vacuum is "empty space". This needed a quantum physicist to explain that particles can pop out of the vacuum because there is in fact so much energy there. 10^93g/cm^3 to be exact.... Gary T Gibbs Gary T Gibbs 9 months ago Love this man 3 Etheoma Etheoma 1 year ago In a large enough black hole you wouldn't get spaghettified, and it's theorised that you could travel back through time using a black hole that was spinning fast enough. Jonathan Moxley Jonathan Moxley 5 months ago Do you think the radiation belt from Jupiter charges the electrical fields of other planets such as our own or helps contribute to the energies of planet earth and it's lifeforms such as plants and perhaps as well as the reason for cancer, and also to include chemical reactions to sustain a/the planets atmospheres and is the radiation belt a contributing factor or even the reason to why we "Humans" have the capabilities to think? Alice Nkore Alice Nkore 2 years ago The simplicity of the questions makes Neil’s answers interesting. I can see myself asking similar questions 10 Nicholas Pitts Nicholas Pitts 4 months ago Q: how does one attain an elevation angle with a curved adjacent? Mr Cat's Wrestling Mr Cat's Wrestling 1 year ago Neil you are my hero of the prophesy 1 Marié telléz Marié telléz 9 months ago Mr Neil Degrasse is an amazing scientist 🌝 HyperOpticalSaint HyperOpticalSaint 1 year ago (edited) One issue on the intelligence side, I thought of this before, but I think there is a big hole in it. Just look at how genetically different dolphin and whale compared to other great apes and yet the intelligence levels demonstrated are rather close. So I think there is a threshold, once you cross that threshold the effect shown by the intelligence just increase by like a million fold, and so far Human is the only thing we know have crossed that threshold. 4 Randy Bonner Randy Bonner 7 months ago I have a question that If it was asked I missed it , but I wouldve asked Mr. DeGrasse " Where would you go took look for life of any kind out in the universe and do you believe there is a planet that once had life but is dead now ? Delusions of Grandure Delusions of Grandure 4 years ago I don’t love the interviewer either BUT he’s interviewed him many times .. so Neil must be diggin it in some way 7 quacks2much quacks2much 1 year ago Tyson is interesting and I respect him. However, he is wrong that Dawkins is not a “communicator.” Disagreeing with Hawkins doesn't make him a non-communicator. He described the god of the Bible perfectly. Dyson dodges and weaves, which is understandable because many people stop listening when their delusions are challenged. Dave Winfrey Dave Winfrey 1 year ago I can only imagine how amazing it would would be to get so very stoned or maybe even "open your mind" with a great hallucinogenic like acid or whatever and go to a live NDT speaking. 4 Manuel Gallego Manuel Gallego 7 months ago At this point I'm formulating a concept of the vastness of the universe in relation to infinity. I can feel myself going mad. Tylor Miranda Tylor Miranda 7 months ago Neil, Please answer. If a black hole has the ability to hold back light from escaping, then how is light the fastest thing in the universe? Ron E Ron E 4 months ago Disclaimer on Globes purchased at stores: "Note: For Neil DeGrasse Tyson - Not to scale" 🤣🤣🤣 1 Alan Cantu Alan Cantu 1 year ago If only more high school teachers were funnier and more exciting like Neil. The impact would be tremendous! 2 Judy Thompson Judy Thompson 4 months ago he just has such fun with what he does. Chris in Cornwall Chris in Cornwall 7 months ago Such an incredible talent to break down and express theory's in a way we all understand 8 lonelyp zinck lonelyp zinck 5 months ago Hey Neil, If you has a bath big enough to float Saturn how deep would it sit? Ring level, or barely perceptible at that scale? Hảo Nguyễn ♡Vietnam Hảo Nguyễn ♡Vietnam 4 months ago i love the discourse between them, good luck finding something like this in today's time. 2 Tommy Madison Tommy Madison 10 months ago Yep , true genius Joshua Hammel Joshua Hammel 1 year ago One of your better interviews on the subject of religion Niel. I miss this open minded approach you used to have. 1 Academiclibrary Academiclibrary 2 months ago I liked the conversation about intelligence. I would add, I would think that intelligence is secondary feature of life unlike locomotion and eyesight.

Like I think it’s safe to say that mammals and birds are slightly smarter overall than the average non-avian dinosaur from 65 million years ago, and that dinosaurs are smarter than what proceeded them. So intelligence, even on dog-like level seems like a late game feature of life. Rich Rich 4 years ago The interviewer definitely made this difficult to watch. Dr. Tyson was great as always and never ceases to amaze! 20 fenderstratguy fenderstratguy 1 year ago (edited) 32:23 What an intentionally ignorant position to take. Unbelievable 32:56 What a fabulous answer from NDT. He is an incredibly wise man. 2 Zox1c Zox1c 1 year ago (edited) makes me wanna cry knowing ppl dont know we're here thinking our universe is just starting while we're here watching youtube videos and chillin knowing our universe/planet has gone through generations and generations 19 Vin Von Voom Vin Von Voom 1 year ago Defense Attorney Neil DeGrasse Tyson vs Prosecutor Robert Krulwich in the case against Cosmic Quandaries is what this video feels like with Robert here. 1 Neil Gallagher Neil Gallagher 1 year ago Neil is such an amazing guy! Great name as well :) 1
