@@skynative0099 What do you expect from someone called "Enter the Bragn"? He probably feels intimidated by Thorne's intellect and decides to leave a quick slander of him and then run away.
Explanation for Interstellar starts at 24:00. It has to do with what it would look like to the human eye. But watch the whole thing for God’s sake, Kip Thorne is a treasure.
@@chrisstevens-xq2vbI have no idea what you're trying to say, but no. That's nowhere near what he says. You're very badly misunderstanding. Or more likely, not even attempting to understand what he is saying.
@@chrisstevens-xq2vbHonestly this whole talk is at an early college level. So if you're not understanding it, I just hope you're young and you'll get it one day. Otherwise.... 😬
I was at this lecture, and let me tell you, this blew my mind. I had the pleasure of learning so many things I didn't know before. I went with a small group of scientifically gifted pupils from my school, we were invited by the university.
@@z9ao7v I only went because there was an empty space. I hated all science except for when we did classes on space. Lol, sorry if that sounded like I was boasting or something. I really didn't mean it like that 😔
Couldn't stand the rhetoric of absolute fantasy this cretin pushes. Nothing in this lecture is tangible or demonstrable empirical evidence . No one has been to the Moon or supposed space, complete pseudo science and brain washing.
@@ossiedunstan4419 As no one has been, gone or going to supposed space. As just the other week the actor Hopkins dropped it's stage prop, the inflatable globe on board the supposed ISS fantasy station. The globe dropped straight to the ground and Hopkins is in a so called weightless environment. Kip loves paper, chalkboards and magical words such as 'gravity", 'gravitational waves' and 'worm holes'. So are you into pseudo science such as this lecture?
The matrix was the imagination of film writers ( who understand nothing of the real world ( Jupiter ascending is another one.), any one in science trying to use it as a foundation should be burnt at the stake ALIVE.
@@expertinanything5462 That's a pretty jaded take, don't you think? You even go as far to add 'soooo disappointed' to make it sound even worse. Wtf made you such a grump?
And did you notice that he is so delighted with the discovery of gravitational waves that he periodically recreates the chirp sound with his mouth throughout the lecture.
I absolutely love the God complex. Its called theoretical physics for a reason! Because it's not facts they try there best to learn more and more about less and less until they know nothing at all!
@Astute Cingulus When you have Weinberg standing beside you agreeing with you, then I'll be impressed. Hell, even *I* figured out that the Big Bang was an adiabatic phase transition, and I never spoke to Wheeler- I only stood next to him while he drank a beer at the Oklahoma State University Physic Club mixer. I missed Weinberg by a month at Austin.
Craig Wall you’re not impressed by Kip Thorne, and couldn’t resist name dropping in your comment? That’s just pretentious. I’ll bet you play bongos too and claim you did so first.
An absolute masterclass in scientific communication to an eclectic, mixed technical and non-technical audience. He does it so effectively that it looks effortless… but in truth, this is one of the hardest things to achieve as a scientist, and I’ve seen other Nobel Laureates give lectures that were very hard to follow
I follow most topics on Physics and Space, yet I was able to learn something in this presentation, due to Dr. Thorne being a great presenter, and good production of this lecture. I remember watching live when the discovery of gravitational waves was announced, but this lecture put it in better perspective for me on the difficulty of that project. Incredible work and dedication by all of the people involved!

Thank you and congrats everyone involved because certainly nothing great can come without amazing collaboration, across the board no matter what the field right?! 🤚😆
Kip Thorn is outstanding and clearly a good man too. I watch this lecture anytime I am troubled and need to take myself away. But what is also striking is the generosity and decency in the comments - Kip obviously attracts good people
A wonderful presentation. It is amusement to hear the story of GR (gravitational wave) and LIGO from Professor Kip Thorne who won Nobel prize for this job. Thanks for him and for University of Cardiff for this ‘memorial’ video. Human beings were non-existing when the incident happened 1.3 Billion years ago. This is amazing (!) Human-Brain’s capability to reconstruct the past and contemplate the future! This, in a sense, is a ‘Time-Travel’ but in what ‘space’; I don’t know. Anyway, Great scientists and engineers deserve the prize.
Absolutely fascinating! Kip explained the creation of the universe, wormholes, time travel, and so much more, that my brain literally exploded, and I had to spend hours cleaning it off my walls and trying to stuff it back into my pathetically insubstantial cranium!
"Interstellar" and "Arrival" are my 2 all time favourite film! I'm not what you'd call a "educated man" but since I left school (17 years ago) iv been obsessed with everything Physics related, iv read all Stephen Hawkins books aswell as other scientists books, (i have a portrait of Albert Einstein and Stephen Hawkins tattooed on my rib cage) and even tho I can't understand any of the real Math, people like Kip Thorne, Brian Greene, Leonard Suskind, they describe any of the subjects in a way I can understand and im slowly understanding more and more of whats being talked about. The book Kip Thorne wrote for Interstellar is absolutely brilliant, if no one has read it I'd highly recommend it 👌
Watching this video while the TV shows the local news in Brazil, I remembered the quote from the movie Contact: "You're capable of such beautiful dreams, and such horrible nightmares."
As you read these comments you might notice those who have very great intelligence but suffer from lack of education and/or mental illness. To see a man such as Dr. Thorne who is both brilliant and mentally stable is remarkable. What he and others who are also so fortunate have done for us is amazing.
thank you, sir .. for the statement about collaboration... science should never be a competition... if it becomes one... we won't get very far together... but together we certainly will
Try looking up 'ton 618'. The largest black hole we know of right now. Keep in mind that it is very likely that a larger black hole exist. We just lack the methods to measure those
lol, there is a place as big as the solar system in space somewhere that we have no clue what goes on inside of it. There could be a dancing unicorn inside but we can't prove, or disprove it. and we may never know. But to find out means to never return to tell anyone.
As a physicist, I had the chance to read the wonderful book written by this wonderful man having the same name as this lecture. I wish I also had to chance to learn how to make accurate measurements in Astrophysics as Mr. Kip Thorne during my PhD. venture... But, I conceptionally believe that time flows backwards inside a black hole. So your dear wife would have been getting younger as she were spinning inside a black hole... So a black hole must be the best place to get anti-aging therapy...
I have been reading about his work in Analog SF&F fact articles, by John Cramer and others, for 26 years; so glad to finally put a person with the name. Inspiring guy.
Questions: (1) What is space expanding into? (2) What is time? (3) Where does spacetime come from? (4) Why was the universe born hot and dense to begin with?
1) the big bang is not an ex-plosion, something that goes outside. The big bang is an implosion. So the whole universe is in a point right now as we speak. We are looking at the inside of a point from the inside. We are looking at the potential of a point.
4) the universe was born hot relative to the temperature now. The hot then got converted into the space now. At a quantum scale, the universe is eternally boiling. The boiling is fluctuating space time that is warped into what we call matter. So it turns out the universe is empty of objects.
3) space time is around the singularity like an electromagnetic field is around a planet. That is the simple version. A donut shape. Next step, every singularity is identical, only the surrounding (space time) changes. Now your donut has black holes that are connected at the center. Next step is stranger. Every point on the donut is a singularity. So where ever you are you are in the singularity as the singularity. You observe it all as space time.
1) Itself 2) Time is the measurement of the entropy of the Universe. 3) The Big Bang ... (part 2: And ... nobody knows. To be even more depressing, no one will EVER know) 4) Because that was the particular properties of the BB singularity (see answer 3 part 2)
@@ajstephenson5583 it turned me straight into physics, cosmology, particle physics, and just basically being an exceptic for the rest of my life, etc. it changed the way I saw the world as a whole. That book and “A demon haunted world” by Carl Sagan.
@@DavidVillasmil i’m glad man, I’ve recently got into astrophysics after taking a physics course in high school this year and I honestly have never been more fascinated by a subject in my life. Any other books you recommend?
@@ajstephenson5583 sure, I would highly recommend Brian Greene’s “The Elegant Universe”, I’ve never read a better explanation as to why time slows down as speed increases, it’s just amazing. I would also recommend Carl Sagan’s “Demon Haunted World” which really teaches us to be skeptic about everything we don’t yet know/understand, and the early work by Michio Kaku “Hyperspace” and “parallel worlds”, also very good reads. And on a different subject, but incredibly mind-opening book “Sapiens” by Yuval Noah Harari. Go to Amazon and search for “Cosmology”, there are some jewels there.
*Kip making dinner for his family* Son: "Why can't we have pizza tonight, dad?" Kip: "Well, you see son. You think we would be able to have pizza. However, when I was working on the set of Interstellar... "
FYI, Kip Thorne was an “authenticity expert” hired by the director of Interstellar to make sure the story they told matched the actual known science at the time the movie was made.
Vivian Ng three times for me so far. I just can’t get enough of that film. Same with the films Contact, 2001: A Space Odyssey, its sequel 2010, and Arrival. I much prefer science fiction heavy on science/light on pseudo-alien melodrama.
In normal case, gravity between 2 objects is 4 times weaker when object is moved 2 times further away from the other body. In a case of a black hole and some lighter object close to the black hole it isn't the same. It's very hard to describe in words how it looks like, but imgaine a twisted gear shaft (wider at one end). 1.bp.blogspot.com/-OkjFbNa5UEA/XXof5Rp_gvI/AAAAAAAABA0/t4RLFUGIZuUdLbw-LTZOQCNwoPXF9WHawCLcBGAsYHQ/s1600/Helical%2Bgearshaft.jpg If a black hole was inside that gear, then smaller object would move up and down in those threads when moving to the center of the black hole. "Threads" are where jets form, when matter falls into a black hole.
It seems to me that this could be explained by analogy to special relativity. SR time dilation makes an object accelerate "not fast enough" for the applied force when it's close to lightspeed, and I believe you can model this as it accelerating normally in the Newtonian sense, but with the increase in time dilation hiding some of the speed increase in such a way that, by f=ma, the outside observer instead "sees" the object get more massive. This is only an analogy, but I think it works. The radiation of ever-stronger gravitational waves by e.g. co-orbiting black holes is a constant drain on their gravitational potential energy - it's why the GW reaches a sudden climax rather than asymptotically increasing in frequency. So in the same spirit of analogy, if you look at this from the assumption that GWs do not exist, that potential-energy drain looks like a gravitational force that increases in strength the closer together they get. Am I on track here anyone?
@@musicalfringe Kip Thorne said that the generation of the GWs had consumed the mass of three suns. And that "chirp" did show increasing frequency which stopped as soon as the black holes merged. However, I feel that there's a corresponding reduction of frequency as the combined mass settles down.
@@zuzusuperfly8363 I mean the, LIGO evidence (the chirp) given is not sufficient to justify the claim, it is like selecting one pixel of a single frame of a motion picture film reel and declaring you understand the entire narrative!
There is a great idea! For the dark side of the Universe - suppose that it consists of short-term interactions in long-lived fractal networks, the smallest quantum operators - Spherical «rosebuds», consisting of a large set; 1 - rolled into a sphere, 2 - half rolled into a sphere and 3 - flat, vibrating quantum membranes relative to their working centers in the sphere.
He is wrong. I really don't know why he says that. We can ever be sure if it's really flat, but for all we can measure, it's still as flat as it can be. Really wonder why he says that? Maybe he believes it to be the case, but he shouldn't say it in lectures. It's just wrong. There are also a lot of analogies that are at the edge of being wrong, if not plain wrong. Like saying a horizon is a sphere. It's not even a well defied region of space-time (it depends of where the observer is), and it's a pure surface, technically.
@@jojolafrite90 Yeah, how dare he say the horizon is in the shape of sphere! Everyone knows black holes are square! Pure surface? Not a defined region of spacetime? The woo is strong with this one.
@Daniel Boyd I understand your frustration. I too tend to think "oh, no, not again!" as soon as I see the word Flat. The crazy flerfers have been working hard on claiming that word, and unfortunately it looks like they are almost winning that race... But in this case I was talking about the Universe, wich for the majority of scientists in the field is thought of as being flat.

Well, let's not forget that science in reality it's an ever-changing tool we use to explain the things we see, it's not perfect and it doesn't have too, there are things that we will never get to see, but we can work around that using some logic, imagination and using what we have available at the time to somewhat get an approximation of how it might be, because there is no way we will never be able to prove what's inside a blackhole or what's beyond the observable universe, we went from worshiping gods to the empiric way in so little time (seeing humanity as a whole comparing them to other species) that, if we stick with this tool, we might be able to understand the universe in ways we can't even fathom right now, if we don't end up killing each other with that knowledge of course xD
Way better than church !!!! The only thing missing ( or i overheard it ) is a clear definition of "warped" , but _what_ a journey this was - i never got my PHD , but i sure got my PHEW here 💪🙏👊
@@abhineet_2225 Warping , as far i understand that SF term , is taking a kind of shortcut through the space-time continuum , like travelling through a wormhole which connects remote co-ordinates - it's Fiction , not Faction
@@Flailfist_Jr Ahh, okay. I always used to get confused when it was explained through the "paper folding" method. Like, how could space-time, a physical quantity be warped or curved that ways. Well, it's probably a thought I guess because it'd take negative matter (so as to have gravitational repulsion to sustain the pathway), which is far away from being considered as existential stuff🥲
17:38 the most interesting computer simulation of what a black hole looks like, ant the camera switches on the back of the heads of people in the room. Fail!
This happens waaaay too often in videos of science lectures at universities. I think the actual camera work is coordinated by humanities majors, who just don't realize how important charts and graphs and other graphic data representations are.
Don't read the comments, they're full of mouth breathers who think quantum mechanics isn't experimentally verified and black holes hasn't been observed. Educate yourselves, read about the history of the standard model, watch a documentary about how the black hole images were generated (Spoilers: two independent teams analysed the raw data while never taking a peek at the final results to prevent bias, and the resultin images matched)
@witkrieg todd I wouldn't put too much faith in Dr. Pierre Marie when it comes to astrophysics. His ideas on CMB and BBR have been shown to be problematic on numerous levels.
I don't understand the interstellar comparison. He said the picture we took with the event horizon telescope is a view from the top that's why we don't see the disk, but our perspective from earth is towards the side so why doesn't it look like interstellar?
So four things I'm not at all smart, I like to try my best at learning things, so I am right in saying gravitational waves are faster than speed of light? And I said ages ago to someone who said I was wrong but from the look of the black hole I said it must have a north and south, is that correct? And with frequency, I was told one of the frequencies either radiation or microwaves shows heat the more you see expand means it's producing heat (not sure if true) but it just popped into my head if we can then see heat in frequency does that mean the emptiness around that frequency mean it's cold? And finally, so far that I know noise can create light called sonoluminescence, but is it possible the light/aura whatever it is that we see around a black hole is sonoluminescence?
