"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.

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.
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."
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

I don't get how/why the person who edited this video thought it was a good idea to switch to the camera at the back of the auditorium _whenever there was a video playing on the screens._ The close view single screen on the left of Kip Thorne has a very clear image and we can see what's going on perfectly. However the far view of the three screens is very blurry and we can barely see a thing. And yet the video switched to that camera whenever a video is playing for inexplicable reasons. It happened once with the first simulation of the black hole by Double Negative (17:33), it happened twice with the second simulation (at 23:43) which explained why there is a difference between the predicted black hole and the observed one, so I am quite certain it is a kind of bizarre, self-sabotaging pattern of the entire video.. _Why?_
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)
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?
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...

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.
well I think the use of "see" here would be the problem. If we speculate that gravitational waves can have macroscopic effects you still wouldn't be able to "see them visually" in the sense that you would also be stretched and squeezed along with space hence you not being able to "see" any macroscopic effects. However! using gravitational wave interferometers (especially the ones that are currently theorized and not operational) I'm sure the effect would be very pronounced if you happen to be very close to a BH/BH merger!
@@ZUvNy2AdjbXB3 Yeah, I should have used "observe" instead of "see", because I was thinking about all kinds of effects that you could detect in various ways. How close does a solid object have to be to be structurally affected? If you would drive your spaceship there, how do you have to be to get small fractures in it when the space is stretched? How close can a human be before the gravitational wave damages our tissues?
Johanna Geisel again i don’t think that would be a possibility because you’re thinking of the matter being stretched and squeezed From my understanding because space time itself of being stretched and squeezed those effects just wouldn’t happen i think because we usually picture a cartoon when we think of stretching and squeezing we have this image in our head of what it would look and feel like. except that’s not what’s happening when space time is being stretched and squeezed. i guess the closest analogy i can think of is “feeling the flow of time”. you wouldn’t feel like you’re “in slow motion” if you went close to a black hole, everything from your perspective is normal it’s just the outside observer that thinks you’re slowing down. same thing happens in terms of gravitational waves. you’re observing objects and space time stretching and squeezing due to LIGO but those objects don’t “feel” physical effects of stretching and squeezing because they are not being stretched and squeezed, space time itself is being stretched and squeezed i hope i’m making some semblance of sense lol
@@ZUvNy2AdjbXB3 If there are indeed macroscopic effects, we would be able to feel them or see them as a ripple. After all, the waves do produce a change in the distance between the mirrors which we're able to detect using lasers and the rest of the paraphernalia.
@@isaacmadhavan I guess you're right - heres an article that says you'd feel something if you were reaallllly close but we're talking about being "stretched by 1-2mm".

@@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!
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.
It's actually incredibly accurate, all known theory agrees with Kip's mathematics for it. Of course, the creative liberties that Christopher Nolan took with it, though, such as it being a "gentle singularity" are purely fiction.
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.

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🥲
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?
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
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.
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.
So the thing that is dropped in the rubber sheet isn't a rock, it's a spiky ball that grabs the sheet. And it's spinning, twisting the fabric itself rather than just pulling it. What would it take for spacetime to snap back to normal spacetime?
I am amazed how physicists present theory as fact. Big bang, theory. Reality, theory so black holes are theory by default. Wave particle duality, interpretation of an experiment based on a theory. Space/time also a theory and the worst offender, it's used to prop up relative, with no mention of the fact that relative is used to calculate and explain the different readings one gets from atomic clock at different altitudes.

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 don't think anyone but you have said anything about a flat earth...
@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.
Great talk thanks for publishing.

15:30 black holes as large as the solar system. That really interrupted my train of thought to just consider it.

@@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.
This man is wonderful. Thank you for being.

This lecture is very informative.
I don't get how/why the person who edited this video thought it was a good idea to switch to the camera at the back of the auditorium _whenever there was a video playing on the screens._ The close view single screen on the left of Kip Thorne has a very clear image and we can see what's going on perfectly. However the far view of the three screens is very blurry and we can barely see a thing. And yet the video switched to that camera whenever a video is playing for inexplicable reasons.
It happened once with the first simulation of the black hole by Double Negative (17:33), it happened twice with the second simulation (at 23:43) which explained why there is a difference between the predicted black hole and the observed one, so I am quite certain it is a kind of bizarre, self-sabotaging pattern of the entire video.. _Why?_
Deserves expulsion. No chance of appeal.
I believe it was because Kip was pointing with the laser pointer while explaining
Wow. Really really advanced physics
Could there be a connection between the strangely shaped orbits around a singularity and the unpredictability of electron position around a nucleus?
Good point
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) nothing 2) entropy 3) the big bang 4) unknown
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)
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?
The universe must be full of gravitational waves just like waves washing up on an ocean beach. We are probably surrounded by little black holes.
maybe we live in the ocean???

Absolutely brilliant. This is why I fell in love with astronomy
The orbit of the little black hole going around the big black hole seemed to me to be similar to an electron orbiting a proton.

You can make an estimate based on the density of matter, energy and radiation observed per unit volume.
And raise it up to represent the observed universe.

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.
@@jmmahony maybe it's a copyright problem?
I would love to know how close you would have to be to merging black holes to see a macroscopic effect of the gravitational waves.
well I think the use of "see" here would be the problem. If we speculate that gravitational waves can have macroscopic effects you still wouldn't be able to "see them visually" in the sense that you would also be stretched and squeezed along with space hence you not being able to "see" any macroscopic effects.
However! using gravitational wave interferometers (especially the ones that are currently theorized and not operational) I'm sure the effect would be very pronounced if you happen to be very close to a BH/BH merger!
@@ZUvNy2AdjbXB3 Yeah, I should have used "observe" instead of "see", because I was thinking about all kinds of effects that you could detect in various ways.
How close does a solid object have to be to be structurally affected?
If you would drive your spaceship there, how do you have to be to get small fractures in it when the space is stretched?
How close can a human be before the gravitational wave damages our tissues?
Johanna Geisel again i don’t think that would be a possibility because you’re thinking of the matter being stretched and squeezed
From my understanding because space time itself of being stretched and squeezed those effects just wouldn’t happen
i think because we usually picture a cartoon when we think of stretching and squeezing we have this image in our head of what it would look and feel like. except that’s not what’s happening when space time is being stretched and squeezed.
i guess the closest analogy i can think of is “feeling the flow of time”. you wouldn’t feel like you’re “in slow motion” if you went close to a black hole, everything from your perspective is normal it’s just the outside observer that thinks you’re slowing down. same thing happens in terms of gravitational waves. you’re observing objects and space time stretching and squeezing due to LIGO but those objects don’t “feel” physical effects of stretching and squeezing because they are not being stretched and squeezed, space time itself is being stretched and squeezed
i hope i’m making some semblance of sense lol
@@ZUvNy2AdjbXB3 If there are indeed macroscopic effects, we would be able to feel them or see them as a ripple. After all, the waves do produce a change in the distance between the mirrors which we're able to detect using lasers and the rest of the paraphernalia.
@@isaacmadhavan
I guess you're right - heres an article that says you'd feel something if you were reaallllly close but we're talking about being "stretched by 1-2mm". Thats really cool!

As if you wouldn't mention being the scientific contributor to a major motion picture, especially if it's relevant to the talk.
Interstellar - an incredible movie, the phenomenal work! That film was made until this epochal M87 image showed up.
yup the photo of black hole just took in last year, but the movie is in 2014. How amazing he is!? His speculation is totally correct.
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.
@@russell_szabados yup, I have been watched Interstellar 4 times
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.

Wish I was there to ask inconvenient questions because I have big doubts about the representation of the black hole in the interstelar
It's actually incredibly accurate, all known theory agrees with Kip's mathematics for it. Of course, the creative liberties that Christopher Nolan took with it, though, such as it being a "gentle singularity" are purely fiction.
What are your doubts mark?
You're far too stupid to inconvenience this man with anything other than how underwhelming you are.
55:09 "not an inverse square law" Way to bury your lead. MORE ABOUT THIS, PLEASE!
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?
@@powerzx Describe it mathematically then.
@@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.
@@isaacmadhavan Do the GWs continue at all after merging?

I felt that too. What does warping actually mean..
@@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🥲

Vaibhav Sati Hmm? Did you mean “on” Or “in” Which comment section?
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?
"There will be enormous surprises of which we cannot even dream today". I hope so. Because right now, it seems physics is a bit stuck.

@@phaturtha216 Talking point much?
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
We will soon be deploying AI + GI in this field.
In 10 years you won't recognise anything in science anymore.
@@phaturtha216 doesnt move relative to what?
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.
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)
