Let us seek the answers and settle the question this way. - This is what the Public ( which FUNDS science ) wants. Nothing more. Just don't ridicule this field of study and science and we will get more information.
The section on a stubborn heart made me think of Planck's sentiment on the subject, "A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it..."
Yeah sadly a very true quote regarding human bias. I forget the exact wording but in a book on the glacial lake dam burst floods it discussed about how the hypothesis of J Harlen Bretz for the glacial lake Missoula mega flood hypothesis based off the geological evidence but was met with controversy as catastrophism or the view that there can be sudden catastrophic events in Earths history was against the Uniformatarianism model that geological changes are only gradual. In the closing remark the book said Bretz lived to see his work accepted by the scientific community only because he outlived his opponents. Among humans fixation with age is a real problem with evolutionary origins the shift from what they call fluid intelligence to crystalized intelligence. In the above it also points out the dangers of oversimplification or reductionism. I the case above geological processes can and do happen slowly but when conditions are right catastrophic changes also occur so neither was completely correct both had been stretched too far. Given the number of times in science that the final conclusion ends up finding a combination of factors where multiple competing hypothesis turn out to be co-important rather than just one it does become a really dangerous side effect of reductionism. The argument over how many spiral arms the milky way has is another example that comes into mind and there is building evidence that MOND and dark matter might both be needed (or rather that MOND observations arise from the equation of state for dark matter rather than being fundamentally a difference in how gravity works). Being open minded is hard for people and thus I think we need to design our systems in science to account for that bias.
As a 16 year old aspiring astrophysicist, I truly appreciate these videos. I hope to bring a fresh perspective and contribute something to our collective knowledge one day. I also hope that I never become so vain that I am blind to my faults. Thanks :)

Great topic! I hope Perserverance finds alien life. Btw I recommend wathching these movies on Mars: Mission to Mars, Red Planet and The Last Days on Mars.
We take it for granted what NASA accomplished with the two rover landings.. blasting off from earth in one piece, traveling millions and millions of miles to line up just right with another planet which is moving thousands of miles per hour in space, then deploy a parachute, land safely, and be able to communicate back and forth with earth?? that's insane and under appreciated.
Love the video. Percival Lowell may have believed in bunk pseudo-science, but in pursuit of a bogus hypothesis, he built an important observatory that discovered Pluto and expanded the human race's understanding of the universe. Being wrong is the price you pay for occasionally being right - and discoveries sometimes come from unexpected sources with wacky motivations and ideas driving them. We need more Percival Lowells.
David Kipping addresses a particularly difficult topic of our ages with sensitivity and flair. I know, I have lived for science among the most illustrious, yet have relatives who share in the conspiracy theories, on whom I find myself incapable of any sort of influence. I have found the experience humbling and I grasp around for insights. These are hard to come by. This attempt counts for me as one of the rare helpful gem, passionate and sincere, with echoes in its calm intensity reminding one of the late Carl Sagan.
David's science narrative is always so beautifully and elegantly explained! Not only a great scientist himself but perhaps more importantly also a GREAT science communicator! He shares much in the passion of the late Carl Sagan! GREAT SHOW! Please do more!😊👍
Excellent video. The problem with alien hypotheses is that they tend to lead to other hypotheses because people's imagination runs wild, even scientists. Someone once wrote or said we shoud never put an inference after another inference.
I found the following. Not sure if that's what you meant. definitions.uslegal.com/i/inference-on-inference-rule/ Inference-on-Inference Rule Law and Legal Definition Inference on inference rule is a principle that when an inference is based on a fact, that fact must be clearly established and if the existence of such a fact depends upon a prior inference no subsequent inferences can legitimately be based upon it. In short, a presumption based on another presumption cannot be a basis for determining an ultimate fact. This rule was propounded in the case Commercial Credit Corp. v. Varn, 108 So. 2d 638 (Fla. Dist. Ct. App. 1st Dist. 1959) wherein the court held “ in civil cases if the proved circumstances justify an inference pointing to an essential fact which inference outweighs all reasonable inferences to the contrary, it can then be said that a conclusion as to the existence of the ultimate fact is justified by the circumstantial evidence. However, the established rule of evidence is that the court cannot construct a conclusion upon an inference which has been superimposed upon an initial inference supported by circumstantial evidence unless the initial inference can be elevated to the dignity of an established fact because of the presence of no reasonable inference to the contrary.”
Hi Fred! As a non scientist with a greater capacity for imaginative wool gathering than research based inductive gymnastics I’m just wondering if you can expand on this concept to make it clearer what the meaning and implications or drawbacks are? I think I have a general idea but if you hav a minute to clarify I’d appreciate to hear it. From not-mardon account user in Canada 🇨🇦 dec 23/22
I heard that Carl Sagan had compared detailed modern pictures of Mars with Lowell's drawings and in most cases couldn't find any details that strung together could be interpreted as linear features. But there are some features that are clearly linear such as the Valles Marineris and other areas where random alignments, or the borders between areas of different colours, could be interpreted as continuous objects especially if you wanted to believe that's what you were seeing.
Exactly correct!!! There can be no doubt that Lowell routinely observed Valles Marineris at favorable oppositions and as the gigantic global canyon would be illuminated by the changing sunlight during a Martian day. Surely this feature was the observational bedrock on which Lowell made his later more detailed claims of lesser canals. He also accurately recorded the seasonal shrinkage of the polar caps to the point of showing the concentric rings that routinely formed as the pole shrunk. When the Mariner spacecraft finally mapped this 3,000 mile long canyon on Mars it should have been named after Lowell. He absolutely discovered it and recorded it from Mars Hill. BTW I’ve looked through Lowell’s telescope at public observation nights. It’s still a fantastic telescope. I’ve also looked through the 24” refractor at Sproul Observatory at Swarthmore College outside of Philadelphia. I met Peter van de Kamp and knew his colleague Sarah Lippincott. Those large refractors (even with chromatic aberration) are great planetary telescopes.
Your “dreaming in rigor,” is really eloquent, Bill, and a very accurate comment on David Kipping’s work-both in his lab and interfacing with us. More than usual, this video was extraordinary. It’s like those discursively brilliant, gem-scaled, elemental essays once common in scholarly quarterlies, but not so much in the digital, video-dominated media of these times. I haphazardly collect vintage textbooks from the 1870s through 1940s, because no matter how many advances have supplanted the assertions of those texts, the articles are amazing-utter pleasures of language, turns-of-insight, gorgeous vocabulary and Magellanic sweep. Not so surprising, given the autumnal summation quality of the 19th century, and the good fortune of scientists and academics who worked and wrote contemporary with the likes of Bohr, LeMaitre, Einstein, Oppenheimer, Fleming, Huxley, Vavilov, Ramon Y Cajal, Oparin, Pauling and Crick. Their articulations were often stupefyingly rational and always rhetorically graceful and compellingly moral. The exact powers of delivery that describe Prof. Kipping.
Your a very clever man, I really enjoy listening to you and your video productions are great too a special mix of science and philosophy which makes you unique. Please don’t stop. Thanks.
I’ve always been on a certain side when it comes to this topic. I’m still passionate about it but you give me both perspectives in a respectful and easy to understand manner every time and I can’t thank you enough. Just discovered your channel a few weeks ago and I’m very happy I did
This was a great video for explaining how unconscious biases can effect research without it necessarily coming from a malicious place. I love how you really tried to come at this issue with all the nuance required and without becoming dismissive or condescending as can happen so often around disagreements in the sciences. Thank you for taking the time to make this!
This has been one of my favorite channels to watch on YT for several years now. Thank you for all your efforts to share your knowledge of science & nature with all of us.🙏🏼
Most excellent video! Assumptions, preconceived ideas, refusal to accept to believe or even consider evidence to the contrary can only lead to disaster. Not only in science, in every discipline, but also in every aspect of life. Thank you!
I'm absolutely loving your channel! Just discovered it recently and I've been eating up the videos. I love anything "spacey", but much of the science goes way over my head. I do appreciate how you attempt to break down the science so people such as me can even remotely understand such complicated concepts. I also really appreciate how you always seem to cap off the incredibly interesting science with some profound idea derived from these concepts. Amazing stuff!
Putting the real video parts together with the CGI for the Perseverance landing really does make it more real in a way. What I found the most interesting when I first saw the landing videos was how due to the Martian atmosphere and the temperature of the thrusters, you can't even see any flames coming from the rocket. Which gives it a bit of an alien feel to it really, like you're watching real life science fiction with a mysteriously hovering platform.
Best part of this channel. You can watch people who break down and investigate situation achievements or...... You can watch a scientific member explain it to you. Nothing against others explaining things but it really is hard to explain it better than people who understand it better than a major percentage of all the population
I remember seeing a video of Arthur C Clarke a few years before he died where he said that he believes there's plants on Mars, referring to some strange geological features and colouring on the surface, images captured by probes.
My immediate reflection on this enlightening video is that just because Lowell and others even today have been and are misguided, it doesn’t necessarily mean that academe isn’t broken. The anecdote about Lyne and the tacit recognition on the part of his colleagues who applauded his admission is telling: in a reformed academe, saying you got it wrong shouldn’t require that much courage and publishing negative results would garner as much kudos as conforming to the mainstream of opinion. But I am also only human and this piece did two things to me: it cleared my mind and also moved me to tears. (PS Edited: I got Lyne‘s name wrong, even after looking it up! 😂)
Gotta tell you, Professor Kipping, that the work you and the Cool Worlds crew do, just here on YT, is so valuable, and I appreciate the call to vigilance, vis-a-vis a priori bias. I look forward to the next offering, as always.
One of your best videos, inspiring and informative. I read Lowell's books once, and was struck by his immensely intellectual style of writing. One point which I would have liked you to add: both the SETI clichés of the Fermi Paradox and the Drake Equation have the assumption that industrialised alien life is or somehow ought to be common baked into them. I've long regarded them as serious obstacles to clarity of thought about life in the universe.
Thanks! Yes I certainly know what you mean about the Fermi paradox which is predicated upon the assumption of common life, but why do you also say so of the Drake Eqn?
@@CoolWorldsLab - If I understand it correctly (I am not a space professional), the Drake Equation is premised on the implicit assumption that the universe has by now existed long enough that life has been able to reach equilibrium. So the number of planets in a galaxy with life on them, and likewise with technological life on them, is broadly constant over periods of time on the order of the age of the Solar System, and it therefore makes sense to discuss the fraction of worlds on which life appears, the fraction of those on which radio astronomers evolve, and so on. But we know that we are living very early in the history of the stelliferous universe: it is only 14 bn years into a lifetime in which the stars continue to shine (red dwarfs, at any rate) for a period on the order of trillions of years. The question therefore arises whether life is still at an early stage and has not yet reached an equilibrium state - a scenario which is not modelled by the Drake Equation, and therefore tends to be ignored. I hope this makes sense!
@@Astronist Your observations make perfect sense. Nonetheless, only 500 million years passed between the birth of the earth and the first unicellular life. So..... even if we're very special, there's still ample room for other planets to do something similar.
@@nicolasuribestanko - True, assuming that life evolved from non-life on Earth. Which it may or may not have done - if a crucial step in that evolution requires a low-gravity environment, then all bets are off. Further, we as yet have no information on how common or uncommon it is that a planet resembling Earth for most of its history (up until the Cambrian explosion) produces a species capable of creating a technological civilisation.
I just wanted to thank you for the channel and the content you post, I have no scientific background whatsoever and for me your videos are a enjoyable way to learn about the universe and science. Keep the good work, and thanks.
I’m reminded of a quote: “Why are you surprised when people fail, as if by some miracle they made a mistake? You should instead be constantly surprised by the miracle that things work as well as they do, and we aren’t constantly thrown into chaos.”
I really like the way he explains everything. Very calm voice and easy to follow. Very intelligent, handsome and charismatic aswell. Glad I found this channel.
You and downtherabbithole are my favourite channels The top notch scientific approach accompanied with poignant music is filling my heart with joy. Thank you for that!
I found your channel fairly recently and this is my first video, I just wanna say that the production quality is magnificent. This is a truly amazing documentary, not to mention this is for free.
This video is excellent. It's the kind of thing you'd expect from top-tier publications: a retrospective analysis of an alleged scientific discovery that turned out to be null and what it can teach us about the scientific method. Your videos are usually quite poetic; I like that because they are far more approachable and captivating.
I Actually felt the same way about the opening of the video. Poor Avi. Lol. I don't think oumouamua is artificial, but he has the right to argue that it is, and he makes valid points about how much of theoretical physics has no basis in evidence, like string theories, and yet these theoreticians sell plenty of books without being ridiculed. Ultimately, ridiculing people like avi is only going to drive the most passionate and imaginative young scientists out of the field. Nobody benefits from that
@@stevencoardvenice No need to feel sorry for Professor Loeb because he crafted a beautiful argument for his hypothesis. in his book. He would have made a great trial attorney. He is incredibly brilliant.
@@emzywillrich7243 The fact is, nobody really knows exactly what oumouamua was, because of its apparent observed anomalous behavior. So this opens the door for people like Avi to offer his own theory
An outstanding video, not only for its science value, but of how we should all treat each other, keep an open mind and be strong enough to admit when we're wrong.
The mars landing sequence leaves me with hope that one day you will create science ova's with awesome electronic music. I absolutely love these videos and the ambience they have.
Professor Samuel L Phelps also popularised the notion of cities, towns etc, on Mars, in his book, World Making, in 1895. A very popular narrative in that era. Wonderful exposition from Professor David, much appreciated by this 80 plus old guy.
Wow.. You deserve millions of subscriptions and views. This channel deserve so much more than this. Keep up the excellent work! Thank you so much for the great content!
If yourself and Prof Brian Cox combined forces and released an audio discussion, the soothing tones would relax any listener into a gentle slumber for a hundred years. Add David Attenborough for an additional 50 yrs if required
So fun to take this deep dive into the Martian Canals! Thank you! Am writing an audio play based on THE WAR OF THE WORLDS and so have been swimming in the world of Martian lore of the very early 20th century.
He has something better - a UA-cam channel. Unlike people with their own TV shows he does not have to kiss corporate ass for good time slots, or persuade marketing executives his show has enough demand to generate returns. He does not have to deal with upper management meddling into his content to suit their views, agendas, or chase fads. UA-cam has many flaws, but it is far, far better than TV ever was.
What an insightful videocast this is. I'm a research student in cultural studies, and this is such eye-opening content in terms of how to do research in any field. I think your discussion on the sine qua non of alternative ideas that constantly question the fallibility of one's own viewpoint is fundamental to any progressive and transformative research.
Honestly this reminds me of the latest discussions going on about Planet 9 & 10. People are so eager to find them they make it sounds like the planets must be out there without question.
I'm Glad that, I accidentally found your channel 2 or 3 years ago and immediately subscribed. You should upload videos more often that's my only request.
I was gonna say the same thing. M1D gave it away. Either way I love this channel as much as I love sn10s backflip to celebrate its landing today. Go Mars!!!!
@@anthonystark7873 Upon taking up my own research I am starting to lean toward the inter dimensional theory. All this being said we still don’t have any concrete evidence for it, maybe one day we will know 🙂
The production of your videos is through the roof. I applaud your humility So sad when you can’t concede. That’s where you distinguish the boys from the men
People don't realize how important this video is. I always quote Christopher Hitchens when anyone makes big claims, Hitchens said "extraordinary claims require extraordinary evidence", I think emotions are very important for human survival but in science you cannot let emotions or pre conception guide your research outcome. Another thing I absolutely loved about this video is that canals were an emerging innovation at that time and so naturally the guy looked for canals on mars, thus us looking for signs of intelligent alien life based on current level of technology is a wrong approach, but then again no body knows what new technology we will have in next 10, 20, 50, 100years snd so looking for unknown technology is almost impossible. Thanks you cool worlds lab and professor for this incredible and informative video. Science never ceases to amaze me!
i think this was a much required lesson for everyone, not only for those with scientific background... thanks for showing us that science is not always beautiful, it too sometimes makes us stutter and fall face down, only to get up once again learning from "the history"... and as always great video 😉
Great video and incredibly informative content along with the rest of the vids on your channel! Even if you did do my boy Fravor dirty at 5:32 lol. I thought his interview with Lex Fridman was very interesting even if I have no idea what to make of it all hah. Keep making amazing vdeos Cool Worlds team!
So glad you covered the psychological aspect of this. The confirmation bias and our egos attaching ourselves to the idea, not letting us admit the idea is wrong after we have invested so much emotional energy and time into it. This is what allows cults to form, and our current state in politics. People attach themselves to a party or a person, maybe based on lies they had been told. But after some time, people cannot admit that they are wrong in believing those ideas, they will vehemently dismiss any evidence provided as fake news, and latch onto any information that supports their beliefs, even if the source is clearly dubious and biased in nature.
If only people could apply this principle to their personal/political lives. Confirmation bias can send us down a figurative "black hole" where we are doomed to repeat the societal mistakes of the past. It is a primal instinct that once helped us survive, but now haunts us in the post modern era. Simply put...there's nothing more uncomfortable then being wrong in something you have put so much time and effort in to. Beautiful video, and a beautiful message of caution regarding the human condition.
Fun topic, fantastic script and editing. If we ever do find evidence of past life on mars we'll know there is so much more to learn about the universe.
Of course, I forgot to say that if you like this video and its message then please do all the UA-cam things to bump the algorithm (like, share, comment)! Thank you again for watching.

I also really appreciate how you always seem to cap off the incredibly interesting science with some profound idea derived from these concepts. Amazing stuff!
Putting the real video parts together with the CGI for the Perseverance landing really does make it more real in a way. What I found the most interesting when I first saw the landing videos was how due to the Martian atmosphere and the temperature of the thrusters, you can't even see any flames coming from the rocket. Which gives it a bit of an alien feel to it really, like you're watching real life science fiction with a mysteriously hovering platform.
Best part of this channel. You can watch people who break down and investigate situation achievements or...... You can watch a scientific member explain it to you. Nothing against others explaining things but it really is hard to explain it better than people who understand it better than a major percentage of all the population
It's always a pleasant surprise to find a new cool world video in my feed!
The quality of production on these Cool Worlds videos is first-class.
Great universal video... very interesting and sophisticated talk. thank you..
I remember seeing a video of Arthur C Clarke a few years before he died where he said that he believes there's plants on Mars, referring to some strange geological features and colouring on the surface, images captured by probes.
Fyi: "Gestalt" is the german word for "shape".
The "G" is pronounced sharp as in "guard" and the "s" is pronounced like a "sh".
Thanks, German never was my best subject at school!
You also mispronounced sequitur quite badly. Love this and your other videos though!!!
My immediate reflection on this enlightening video is that just because Lowell and others even today have been and are misguided, it doesn’t necessarily mean that academe isn’t broken. The anecdote about Lyne and the tacit recognition on the part of his colleagues who applauded his admission is telling: in a reformed academe, saying you got it wrong shouldn’t require that much courage and publishing negative results would garner as much kudos as conforming to the mainstream of opinion.
But I am also only human and this piece did two things to me: it cleared my mind and also moved me to tears.
(PS Edited: I got Lyne‘s name wrong, even after looking it up! 😂)
Gotta tell you, Professor Kipping, that the work you and the Cool Worlds crew do, just here on YT, is so valuable, and I appreciate the call to vigilance, vis-a-vis a priori bias.
I look forward to the next offering, as always.
This channel is truly awesome, you have a divine talent in speaking. Especially about space.
You like fake news he all talk
@@michaelvillarreal4202 Lol, okay Mr. Delusional conspiracy theorist. Why don't you present some evidence of that?
@@FitzgeraldStanburyWeissV get a life 🤡
What a banging song at the beginning lol
Remember! "Schiaparelli" is read as "Skiapparelli"
One of your best videos, inspiring and informative. I read Lowell's books once, and was struck by his immensely intellectual style of writing. One point which I would have liked you to add: both the SETI clichés of the Fermi Paradox and the Drake Equation have the assumption that industrialised alien life is or somehow ought to be common baked into them. I've long regarded them as serious obstacles to clarity of thought about life in the universe.
Thanks! Yes I certainly know what you mean about the Fermi paradox which is predicated upon the assumption of common life, but why do you also say so of the Drake Eqn?
@@CoolWorldsLab - If I understand it correctly (I am not a space professional), the Drake Equation is premised on the implicit assumption that the universe has by now existed long enough that life has been able to reach equilibrium. So the number of planets in a galaxy with life on them, and likewise with technological life on them, is broadly constant over periods of time on the order of the age of the Solar System, and it therefore makes sense to discuss the fraction of worlds on which life appears, the fraction of those on which radio astronomers evolve, and so on. But we know that we are living very early in the history of the stelliferous universe: it is only 14 bn years into a lifetime in which the stars continue to shine (red dwarfs, at any rate) for a period on the order of trillions of years. The question therefore arises whether life is still at an early stage and has not yet reached an equilibrium state - a scenario which is not modelled by the Drake Equation, and therefore tends to be ignored. I hope this makes sense!
@@Astronist Your observations make perfect sense. Nonetheless, only 500 million years passed between the birth of the earth and the first unicellular life. So..... even if we're very special, there's still ample room for other planets to do something similar.
@@nicolasuribestanko - True, assuming that life evolved from non-life on Earth. Which it may or may not have done - if a crucial step in that evolution requires a low-gravity environment, then all bets are off. Further, we as yet have no information on how common or uncommon it is that a planet resembling Earth for most of its history (up until the Cambrian explosion) produces a species capable of creating a technological civilisation.
The first 4 minutes of this video are among the best on all of UA-cam. That was as inspiring as anything I’ve ever seen on the platform.
I just wanted to thank you for the channel and the content you post, I have no scientific background whatsoever and for me your videos are a enjoyable way to learn about the universe and science. Keep the good work, and thanks.

@@michaelsimmons1430 I will, thanks a lot. 😁
No problem fam
How can anyone possibly dislike these videos, it makes no dam sense to me what so ever, such amazing content.
It's just the Joe Rogan, Bob Lazar, etc groupies
Misclick probably cuz i somwtimes do that

I’m reminded of a quote: “Why are you surprised when people fail, as if by some miracle they made a mistake? You should instead be constantly surprised by the miracle that things work as well as they do, and we aren’t constantly thrown into chaos.”
I really like the way he explains everything. Very calm voice and easy to follow. Very intelligent, handsome and charismatic aswell. Glad I found this channel.
You and downtherabbithole are my favourite channels
The top notch scientific approach accompanied with poignant music is filling my heart with joy.
Thank you for that!

@@michaelsimmons1430 He is quite cool, but the topics he covers are a little bit too utopian imho.
Nevertheless thx for your recommendation!
I found your channel fairly recently and this is my first video, I just wanna say that the production quality is magnificent.
This is a truly amazing documentary, not to mention this is for free.
I loved the Perseverance landing sequence! 🤩
I could feel what the emotion of the entire landing.
That was a killer opening sequence.
This video is excellent. It's the kind of thing you'd expect from top-tier publications: a retrospective analysis of an alleged scientific discovery that turned out to be null and what it can teach us about the scientific method. Your videos are usually quite poetic; I like that because they are far more approachable and captivating.
That first minute and 20 seconds I'm thinking, "I hope this is a subtle jab at Avi Loeb."
I Actually felt the same way about the opening of the video. Poor Avi. Lol.
I don't think oumouamua is artificial, but he has the right to argue that it is, and he makes valid points about how much of theoretical physics has no basis in evidence, like string theories, and yet these theoreticians sell plenty of books without being ridiculed. Ultimately, ridiculing people like avi is only going to drive the most passionate and imaginative young scientists out of the field. Nobody benefits from that
@@stevencoardvenice I agree
Thought exactly the same, seems like the whole video has a deeper meaning than the actual title gives!
@@stevencoardvenice No need to feel sorry for Professor Loeb because he crafted a beautiful argument for his hypothesis. in his book. He would have made a great trial attorney. He is incredibly brilliant.
@@emzywillrich7243
The fact is, nobody really knows exactly what oumouamua was, because of its apparent observed anomalous behavior. So this opens the door for people like Avi to offer his own theory
Goodness gracious . Thank you . Your voice is like a dart of silk wrapped tranquilizer !
An outstanding video, not only for its science value, but of how we should all treat each other,
keep an open mind and be strong enough to admit when we're wrong.
As someone who spent 4 years on "it's probably noise" during my PhD I very much enjoyed these stories.
Excelent video, excelent editing skills, excelent information. Thank you. Good luck to you and your team :)
Really nice comment. I'd just like to point out "excellent" is spelled with two Ls.
Really not a big deal, but the repetition got to me lol
Much appreciated!
@@Direblade11 :D okay, noted - English is not my native language :)))) And I don´t use excellent often as well :). Thank you for the correction :)
The mars landing sequence leaves me with hope that one day you will create science ova's with awesome electronic music. I absolutely love these videos and the ambience they have.
So weird - I literally just checked this channel a few minutes ago to see if you had uploaded! I sensed a disturbance in the force!
Same here!!
Professor Samuel L Phelps also popularised the notion of cities, towns etc, on Mars, in his book, World Making, in 1895. A very popular narrative in that era. Wonderful exposition from Professor David, much appreciated by this 80 plus old guy.
I needed this today. Thank you for your amazing content and scientific work. Always with a message and information that needs to be heard.
Wow.. You deserve millions of subscriptions and views. This channel deserve so much more than this. Keep up the excellent work! Thank you so much for the great content!
Saw your name in Scientific American. They did a story on exo-moons. Good stuff!
If yourself and Prof Brian Cox combined forces and released an audio discussion, the soothing tones would relax any listener into a gentle slumber for a hundred years. Add David Attenborough for an additional 50 yrs if required
So fun to take this deep dive into the Martian Canals! Thank you! Am writing an audio play based on THE WAR OF THE WORLDS and so have been swimming in the world of Martian lore of the very early 20th century.
This guy should surely have his own t.v show. 😻
T.v is dead
@@TheMongolianMage l can live with that.
He has something better - a UA-cam channel. Unlike people with their own TV shows he does not have to kiss corporate ass for good time slots, or persuade marketing executives his show has enough demand to generate returns. He does not have to deal with upper management meddling into his content to suit their views, agendas, or chase fads.
UA-cam has many flaws, but it is far, far better than TV ever was.
What an insightful videocast this is. I'm a research student in cultural studies, and this is such eye-opening content in terms of how to do research in any field. I think your discussion on the sine qua non of alternative ideas that constantly question the fallibility of one's own viewpoint is fundamental to any progressive and transformative research.
As a grad student in the sciences, this is a necessary watch
Excellent video. Very interesting, informative and worthwhile video. Many thanks for the posted references.
Found this great channel two days ago, really enjoy listening to you, professor David !
Fantastic presentation. It always makes my day when you put a new video out. Thanks for bringing these stories to life for us.
Honestly this reminds me of the latest discussions going on about Planet 9 & 10. People are so eager to find them they make it sounds like the planets must be out there without question.
I'm Glad that, I accidentally found your channel 2 or 3 years ago and immediately subscribed. You should upload videos more often that's my only request.
2:20 That audio was seriously screwing with me, we had a Mars landing, a SpaceX liftoff, and a SpaceX landing going on all at once hahaha
Haha ye I shoved quite a bit of random radio chatter in there for atmospheric effect, sometimes I give myself a little artistic license...
@@CoolWorldsLab I love it :D
@@CoolWorldsLab Good work.. love this channel! 😊👍🏾
I was gonna say the same thing. M1D gave it away. Either way I love this channel as much as I love sn10s backflip to celebrate its landing today. Go Mars!!!!
I want to know about aliens so much, but I just don’t think we are going to know anytime soon. Great video as always mate 👍
Here's everything you need to know. They are not from another planet in deep space .they are demons from a dimension we can't see in the earth
@@anthonystark7873 Upon taking up my own research I am starting to lean toward the inter dimensional theory. All this being said we still don’t have any concrete evidence for it, maybe one day we will know 🙂
Yes I couldn't have said it better myself
I think aliens may be hiding from us for some reason.
This content shouldn't be available for free but I'm glad it is.
Your videos refill my motivation to keep doing my dissertation on exoplantes. Ty professor Kipping!!
The production of your videos is through the roof. I applaud your humility
So sad when you can’t concede. That’s where you distinguish the boys from the men
Constantly checking this channel for new content. Thank you!
People don't realize how important this video is. I always quote Christopher Hitchens when anyone makes big claims, Hitchens said "extraordinary claims require extraordinary evidence", I think emotions are very important for human survival but in science you cannot let emotions or pre conception guide your research outcome.
Another thing I absolutely loved about this video is that canals were an emerging innovation at that time and so naturally the guy looked for canals on mars, thus us looking for signs of intelligent alien life based on current level of technology is a wrong approach, but then again no body knows what new technology we will have in next 10, 20, 50, 100years snd so looking for unknown technology is almost impossible.
Thanks you cool worlds lab and professor for this incredible and informative video. Science never ceases to amaze me!
You have such a calming way of speaking
perfect narrator , voice is calming
If I had hair, this video would've blown it right off of my head. 😄 This was awesome! And got my heart pumping.
your channel keeps getting better, thank you for doing this. much love
I love the way you move between philosophy and science. Magic atmosphere in most of your videos.
this calm narration is way more relaxing then Alan wats or diazepam
i think this was a much required lesson for everyone, not only for those with scientific background...
thanks for showing us that science is not always beautiful, it too sometimes makes us stutter and fall face down, only to get up once again learning from "the history"...
and as always great video 😉
Very interesting topic, your videos are on point and are narrated very well, keep up the great work!
I like how this channel seems to give space to the rare earth hypothesis.. excellent stuff thanks
Great video and incredibly informative content along with the rest of the vids on your channel! Even if you did do my boy Fravor dirty at 5:32 lol. I thought his interview with Lex Fridman was very interesting even if I have no idea what to make of it all hah. Keep making amazing vdeos Cool Worlds team!
This is the most amazing channel I've ever come across. I Look forward to every video. Thank you!
Thanks for watching!
I love the mix of launch audio for effect. great job!
Masterpiece!
I am amased at the fact that you keep on making better and better content
So glad you covered the psychological aspect of this. The confirmation bias and our egos attaching ourselves to the idea, not letting us admit the idea is wrong after we have invested so much emotional energy and time into it. This is what allows cults to form, and our current state in politics. People attach themselves to a party or a person, maybe based on lies they had been told. But after some time, people cannot admit that they are wrong in believing those ideas, they will vehemently dismiss any evidence provided as fake news, and latch onto any information that supports their beliefs, even if the source is clearly dubious and biased in nature.
If only people could apply this principle to their personal/political lives. Confirmation bias can send us down a figurative "black hole" where we are doomed to repeat the societal mistakes of the past. It is a primal instinct that once helped us survive, but now haunts us in the post modern era. Simply put...there's nothing more uncomfortable then being wrong in something you have put so much time and effort in to. Beautiful video, and a beautiful message of caution regarding the human condition.
This reminds me of a mindfulness meditation class your mic makes you look intriguing, A new version of Mechanical Universe Cool world labs style
Very humbling video, definitely a must watch for anyone interested in the sciences.
That landing montage was well done! The “touchdown” announcement still gets me emotional.
The Kipping Terrascope. Nice ring to it. I 💗 your videos, it makes me want to be an astrophysics when I grow up.
Fun topic, fantastic script and editing. If we ever do find evidence of past life on mars we'll know there is so much more to learn about the universe.
