I hope you enjoy this long video, it took a long time to make but I'm pretty happy with how the simulations turned out! If you'd like to take a look at the codes for the simulations (those shown at 5:56 and 13:35), a basic version of each is available on my shadertoy page : www.shadertoy.com/user/aroussel Several people were also wondering about the first calculation if it was okay to estimate the distance to travel by a straight line : while it is definitely not a realistic trajectory, it is still good for yielding a quick order of magnitude. I wanted to start the video with a very simple calculation, similar to the rough estimates that are used in astrophysics. For those interested in the full calculation, in reality the trajectory would more likely resemble a half-ellipse (see Hohmann transfer), which would be quite excentric due to how far Saturn is from the Sun, and would therefore look pretty similar to a straight line. If we calculate the exact length of this half-ellipse in the heliocentric frame we get 2 billion km, which is 35% off from the result using the straight line. It is of course quite off if we want a precise result, but it is okay in this context since we only wanted to check whether or not the speed of the ship was absurd and unrealistic.

Hello, Interstellar VFX supervisor here. You are correct that the asymmetrical appearance of Gargantua was reduced, we did this by reducing the spin of our black hole simulation from 0.9999c to 0.75c. The shape is correct for a 200 million solar mass black hole spinning at 0.75c. Why did we do this? We preferred the look of the more "classic" circular shadow for aesthetic reasons. We chose not to depict a hotter accretion disc for story reasons - the accretion disc around Gargantua is old, thin, and stable, what Kip described as an "anaemic" accretion disc, with a temperature similar to that of the surface of our sun, so it was just about plausible that our futuristic space craft, the Endurance, might be able to travel near to it. Chris didn't ask us to remove the doppler effect, we just chose not to offer it up. Regarding the wormhole - our DNGR software was capable of rendering a physics-correct trip through the throat of it, but we found it to be not very dramatic, the images that we rendered in this manner do feature in the finished effect, combined with a lot of other stuff that's more impressionistic. Great video! Your hot blue accretion disc is very beautiful!

You just might be the kind of person who would like to answer these questions. I'd like to ask... Supposing there were 6 additional spacial dimentions beyond our known 3 as string theory suggest, and let's suppose those were uncurled up. What formula would you use to determin the radius of a blackhole's event horizon with a given mass in 9 spacial dimentions. Wouldn't the strength of gravity disipate by 1/(radius^8)? Would the higher dimentional black hole not create intense tidal forces that may quickly hawking radiation evaporate even very immense sized black holes? Would you care to speculate if a period of time of universe expansion in 9 spacial dimentions, and later 6 curl up, could result in the smoothness of the universe that we currently attribute to inflation?

@@NeroDefogger This is the formula for time dilation of a circular orbit around a static black hole. It diverges at 1.5x the Schwarzschild radius because that is where lies the photon sphere, under which there cannot be any more circular orbits. Here's the proof of this formula: the Schwarzschild metric (in 2 spatial dimensions, setting Rs=c=1) is ds² = -dt²(1-1/r) + dr²/(1-1/r) + r²dφ². For a circular orbit, dr/dτ=0. We therefore have -1 = -(dt/dτ)²(1-1/r)+r²(dφ/dτ)². Using Euler-Lagrange equation for the r coordinate yields : 0 = -(dt/dτ)²/r² + 2r(dφ/dτ)², which tells us that (dφ/dτ) = (dt/dτ)/√(2r³). Using this we get the equality : 1 = (dt/dτ)²(1-3/2r), or finally : dt/dτ = 1/√(1-3/2r)
I can see why they removed the asymmetry of the black hole and reduced the temperature, to a certain extent. The simpler black hole gives a much more stark representation of the strangeness of gravitational lensing and warping of spacetime, but damn that blue-ish black hole you guys made was spectacular, I would love to see a movie use that simulation.
I can understand taking out some of the goofy artifacts of the rotating black hole, but I feel the high-temperature blue color would have looked amazing on the big screen.
I'm doing a PhD in this field, and I aspire to have your communication skills and physics knowledge. And wow the simulations and calculations are breathtaking. You are an inspiration to myself and many others, thanks!
May I ask what you are doing exactly? I am finishing my masters in Theoretical Physics also and took a course in GR, which was incredible. We touched on black holes at the end, but sadly only the Schwarzschild type. Now I am starting on my thesis on scalar induced gravitational waves!
@@KevinS47 That's awesome to hear! Yea going past the Schwarzschild solution is def a bit hardcore. I do graviton and particle spectra using the AdS-CFT correspondence and Supergravity (low energy approximation of M-theory). Very cool stuff!
@@speeshers That is cool! Certainly harder than GR. I have a friend who's doing something very similar at CERN with AdS-CFT! I don't think I'd be able to get into string theory myself, it's a tad too much ^^ Thanks for sharing!
@@KevinS47 Ofc, and I didn't know they played around with holography at CERN, very interesting. Imo, all this stuff looks impossibly difficult on the surface, but you get the hang of it as you continue to learn and practice more and more. I'm sure I'd look at your research and be completely lost. It just takes some hard work and a lot of patience to get into any of these research fields.
That’s super cool! I’m a physics major and want to pursue a phD and study nuclear physics but I sometimes get discouraged with how difficult things can be. Do you ever feel the same way?
The visuals of blackhole with higher temperature took my breath. So beautiful. Thinking about percieving not an object in space, but an event in time (as said in Veritasium video) with such breathtaking visuals is something beyond comprehension yet somehow poethic.
I love how lovecraftian black holes are. I know it's a cliche to call them that way, and they are not really "beyond human comprehension". But there's still something so eldritch about them, not necessarily in a scary way. They feel like something completely outside of this reality, like visitors from another world. I wonder sometimes if there are other similar exotic objects in the universe out there. I really only know about neutron stars and black holes, there are a bunch of speculative objects but they're not as likely to exist. I really hope that in the next decades we just continue discovering more absolutely mind-blowing objects in the universe.
@@qwertydavid8070 I recently saw a video with real images of the objects in universe for example sobrero galaxy. With real I mean without additional colouring. Just pure human spectre light from regular telescope. If you remove the beautiful colours, the objects appear dull and kind of scary, very alien. Not just black holes, but other objects in universe could have that "lovecraftian vibe". :)
@@mark-p3 Oh certainly, I've seen pictures like that before. I kinda hate how heavily NASA edits their images, I do get why do they do it though. But humans can't see in infrared or ultraviolet, so most space objects don't really look that colorful and vibrant lol. I was more talking about other exotic objects in the universe though. Like, imagine if one day we find a toroidal planet or stuff of the like. I just want to see more objects that push the laws of physics to their limits like black holes do.
@@qwertydavid8070 what i find most fascinating about space is that we can never truly see it 'properly' no matter what we do. We can take all the pictures we can, look through telescopes and see something but our eyes never evolved to perceive anything in space - we are not only limited by how long light takes to reach us and time but also forever limited by human perception itself when it comes to observing space. But we do it anyway.
15:03 my jaw was dropped, in awe of how mysteriously powerful, crazy, and scary this must really be to witness up close... Chills on the skin just seeing this in the virtual representation.
I’ve watched so many different scientists explain these concepts (wormholes, black holes, the singularity, time dilation) and this is the most digestible explanation I’ve ever seen. Incredible stuff bro!!!!
If I am to trust the "uploaded x hours ago", then this video was literally uploaded within 30 mins of me finishing watching Interstellar. Timing literally couldn't've been better lol
Same thing here, just finished the movie for the first time, went to RUclips for more answers and boom, first video on my recommended lol. My phone is either blatantly spying on me, or I'm stuck in the tesseract rn 😂
We need this kind of channels that provide genuine Science education. It's pleasantly refreshing to watch this kind of video out of all other channels that do nothing but stitch random space videos and pretend to talk and predict science. This man deserves a standing ovation!
Keep in mind it was a simulation of a black hole 4 years before an actual photograph of an actual black hole was taken, and the properties and phenomena of which have been revised subsequently. It is really impressive I must say.
The trinity test was so lame. I watched this whole movie waiting for this moment and you used some tnt? Was legit a moment when cgi would have been better.
Kip Thorne, a renowned theoretical physicist and Nobel laureate, was a key scientific consultant for Interstellar. He played a crucial role in ensuring the scientific accuracy of the film's portrayal of black holes, wormholes, and relativistic effects, particularly regarding time dilation and gravity. Thorne's involvement helped bring a high level of realism to the depiction of advanced space phenomena.Kip Thorne initially worked with producer and director Christopher Nolan and his brother Jonathan Nolan (the screenwriter). He provided scientific guidance but also had a significant influence on the storytelling. Thorne ensured that the film adhered to the known laws of physics as much as possible, while also allowing for creative storytelling when necessary. For instance, he and Nolan agreed not to violate the principles of physics (such as faster-than-light travel), but they did allow for speculative ideas like traversable wormholes. Kip Thorne’s involvement ensured that Interstellar is one of the most scientifically grounded science fiction films ever made, blending complex scientific concepts with emotional storytelling.
I love that book! And it’s really cool to see the more realistic visualizations in this video too. I also love that Interstellar was the first time a black hole was simulated in HD. They also had a room full of computers calculating and creating each frame, and even with that it took a long time to create the shots of gargantua. While some of the things in the movie are a stretch (and a handful unrealistic), I appreciate how they made the move as close to plausible as possible (and I also get why and appreciate that they didn’t display gargantua realistically - it’s already a lot to take in)
@@andrewsanford I remember reading that interstellar, just like other nolan movies, had one of the heaviest Reels size and I'm not shocked by the amount of time and computation needed lol. Ray tracing all the frames with that resolution and hence the pixels is just phenomenal.
this video came out on my birthday-interstellar is my favourite movie and you are one of my favourite channels. i was so excited to see you talk about the physics behind it, and it made it even more credible that you relied on kip thorne's book. so thank you so much for this gift! ♡
This was INCREDIBLE. Your simulations are hypnotic, your implementation of real physics and math is fascinating, and the way you explained it was so clear and easy to understand. The best video I’ve seen in a long time!
This continues to be my favourite RUclips channel. The visualizations are breathtaking now, but they are only beginning to catch up to the level you are on regarding knowing exactly how to describe things to your audience to bring topics into grasp which other educators have failed to breakdown in such an accessible way. I have learned so many things from you that I figured I would never learn without an in depth understanding of the math. Thank you so much.
Cooper's Station is by far the most unbelievable part of this story. Not because of its questionable feasibility, but because of the damn housing. This is a station clearly modeled after cylindrical space colonies dreamed up in the mid-century. Space colonies meant for alternative living around a still mostly livable Earth. Not interstellar arks housing the last bit of humanity clinging to survival at all costs. Why on earth would they waste valuable square inches on traditional suburban homes? Otherwise, good one Nolan.
Considering that they have gravity control tech and have presumably been in space for at least a few years, it's conceivable that cooper station isn't the only space station humanity lives on at this point. Once you're already in space, with construction infrastructure and a large population, it's a lot easier to build *more* space infrastructure. To be honest I didn't interpret the end of the movie as the humans leaving the solar system through the wormhole - why would they? There's no longer any rush or emergency. It seems more like humanity has stabilized as a spacefaring society and is now on the path to gradually spreading through the solar system and exploiting its resources as needed, eventually branching out to exploring Gargantua via the wormhole and other star systems via traditional interstellar travel.
@@washingtonirving8240 Bro it still doesn't make any sense. Making such stations would require a LOT of materials and would be EXTREMELY EXPENSIVE. Realistically it would all be very dense housing
This video really made think of black holes, time dilation, gravity, spaghettification and more fore like HOURS.I wonder why this video haven't many views, it deserves more views actually. This video is really mind blowing and the stimulations, the calculations and everything need to be appreciated.Thanks for this video.

Although all the maths go well beyond my head, your way to explain the physics in basic language allow us to understand the basics and visualise how and why things look in the way they do. Thank you so much for bringing this high level knowledge to the masses, your channel is great. I am glad I subscribed although just now I am rediscovering it.

Yeah man, in the internet one place people are getting money by showing there body and here many talented and educated person are struggling to earn bcz of society which is not focusing on them
This video is incredibly underrated. It's one of the most remarkable ones I've ever come across on RUclips. The script, editing, and dedication displayed in it are simply enviable.
I haven't even finished this yet, but felt compelled to express just how amazing this video is. Everything, from the visuals to the explanations, and especially how seamlessly you weave them together is honestly one of the best visual depictions I've ever seen for content like this. Even the way you animate the equations and plug them into others, while not detracting from the visual simulations is just flawless 😮
Holy crap this video was WAY more interesting than I thought it would be. Commenting so the algorithm picks up this amazing content. Love your work, man

@@ScienceClicENthis is the first of your videos I've seen, mind blown... What do you do as a profession, if you don't mind me asking!? Bench welder here.

So this video is incredibly interesting to me, thanks so much. So cool to see the calculations and creation of the visuals. Oh, and to be honest I actually prefer your visuals over those in the movie.
This animation in this video is quite literally the quality that 10 professional animators, working together full time for 6 months, could only hope to achieve. And that's just the animation! The building, intriguing music, the dialogue, and most of all the brilliant explanation talent make this the most flawless educational youtube video I have ever seen. This is really an astonishing level you have achieved. If there were some kind of award with a prize for the most outstanding original RUclips video, this would easily win number one. You would have several other entries in the top 10, by the way.
RUclips copyright system going at it again 😢 Amazing video, hope it blows up as it should. I particularly love the visualization of the inside of the wormhole. It think it looks so much more mesmerizing than the one in the movie.
My method for 'The Copper station' is that in the end of the movie, Copper gets a spaceship. For a moment it show us space relative to the motion of the station, and there we can know it's angular velocity. All what is missing is mesuaring that speed and R=g/w²
i understand why they ignored some things for Gargantua, since a film needs to tell a story and be visually appealing, but i think the simulation with the other effects included looks way cooler and honestly adds to the "fear" factor of the black hole... it looks so alien and foreboding
Not only that, the fact that it looks "weird" raises questions in the minds of inquisitive viewers. At least some of them would seek answers to those questions, educating themselves on topics they would otherwise never touch. It was an anti-intellectual decision to remove all that. And for what? A flimsy "looks better" excuse. Everyone involved should be ashamed.
3:15 I Think A More Accurate Approach Would Be 1.4 Billion km Instead Of 1.3 Billion km. Divide That By 2 Years In Hours And You Obtain 79.900 km/h, Or 49600 mph.
wow. just wow. makes me realise how much work the crew at interstellar did. props to you for making me able to appreciate the movie so much more than i already did.
Repeating my questions from last time (with answers from scienceclic) They would do a hohmann transfer rather than direct flight, but they had some martian and julian slingshots so a direct flight was an estimate for not absurd numbers. The baseball's arc doesn't match it going into the simulated gravity of the other side of the toob.
By the way since your question I have calculated the Hohmann transfer for a Earth - Saturn trip and it is actually not that far from a straight line, both in the heliocentric frame and the frame which corotates with Saturn around the Sun. That's because Saturn is much further than Earth from the Sun, such that the transfer trajectory is a very elongated half-ellipse.
Could the planet Miller not be seen due to the extreme temporal dilation that would cause redshift out of the visible spectrum? (when the astronauts were far from it)
7:30 I am struck by the fact that this isn't what the bulk of the wormhole looked like, considering how much it resembles the tesseract in shades. Your rendering is somehow more stimulating and exciting than the original.
I'm absolutely stunned by the simulation of the interior of the wormhole, and the reallistic simulation of Gargantua is just so beautiful (given I like blue a lot)
I hope you enjoy this long video, it took a long time to make but I'm pretty happy with how the simulations turned out!

It should use as much of reality as possible but it does not. Fantasy movies end up being more realistic than this.
@@pawelhyzopski6456 that is factually untrue
The blue black hole in the above video looks way better
I can understand taking out some of the goofy artifacts of the rotating black hole, but I feel the high-temperature blue color would have looked amazing on the big screen.
Amazing content! A shame this doesn’t have more views. Every Interstellar fan should watch this.
WHY NO COMMENT?
Yo I would like to thank you a lot for donating! [much much, much appreciated... Need more people like you in world!]
I'm doing a PhD in this field, and I aspire to have your communication skills and physics knowledge. And wow the simulations and calculations are breathtaking. You are an inspiration to myself and many others, thanks!
May I ask what you are doing exactly? I am finishing my masters in Theoretical Physics also and took a course in GR, which was incredible. We touched on black holes at the end, but sadly only the Schwarzschild type. Now I am starting on my thesis on scalar induced gravitational waves!
@@KevinS47 That's awesome to hear! Yea going past the Schwarzschild solution is def a bit hardcore.
I do graviton and particle spectra using the AdS-CFT correspondence and Supergravity (low energy approximation of M-theory). Very cool stuff!
@@speeshers That is cool! Certainly harder than GR. I have a friend who's doing something very similar at CERN with AdS-CFT!
I don't think I'd be able to get into string theory myself, it's a tad too much ^^
Thanks for sharing!
@@KevinS47 Ofc, and I didn't know they played around with holography at CERN, very interesting.
Imo, all this stuff looks impossibly difficult on the surface, but you get the hang of it as you continue to learn and practice more and more. I'm sure I'd look at your research and be completely lost. It just takes some hard work and a lot of patience to get into any of these research fields.
That’s super cool! I’m a physics major and want to pursue a phD and study nuclear physics but I sometimes get discouraged with how difficult things can be. Do you ever feel the same way?
The visuals of blackhole with higher temperature took my breath. So beautiful. Thinking about percieving not an object in space, but an event in time (as said in Veritasium video) with such breathtaking visuals is something beyond comprehension yet somehow poethic.
I love how lovecraftian black holes are. I know it's a cliche to call them that way, and they are not really "beyond human comprehension". But there's still something so eldritch about them, not necessarily in a scary way. They feel like something completely outside of this reality, like visitors from another world. I wonder sometimes if there are other similar exotic objects in the universe out there. I really only know about neutron stars and black holes, there are a bunch of speculative objects but they're not as likely to exist.
I really hope that in the next decades we just continue discovering more absolutely mind-blowing objects in the universe.
@@qwertydavid8070 I recently saw a video with real images of the objects in universe for example sobrero galaxy. With real I mean without additional colouring. Just pure human spectre light from regular telescope. If you remove the beautiful colours, the objects appear dull and kind of scary, very alien. Not just black holes, but other objects in universe could have that "lovecraftian vibe". :)
@@mark-p3 Oh certainly, I've seen pictures like that before. I kinda hate how heavily NASA edits their images, I do get why do they do it though. But humans can't see in infrared or ultraviolet, so most space objects don't really look that colorful and vibrant lol.
I was more talking about other exotic objects in the universe though. Like, imagine if one day we find a toroidal planet or stuff of the like. I just want to see more objects that push the laws of physics to their limits like black holes do.
@@qwertydavid8070 what i find most fascinating about space is that we can never truly see it 'properly' no matter what we do. We can take all the pictures we can, look through telescopes and see something but our eyes never evolved to perceive anything in space - we are not only limited by how long light takes to reach us and time but also forever limited by human perception itself when it comes to observing space. But we do it anyway.
15:03 my jaw was dropped, in awe of how mysteriously powerful, crazy, and scary this must really be to witness up close... Chills on the skin just seeing this in the virtual representation.
I’ve watched so many different scientists explain these concepts (wormholes, black holes, the singularity, time dilation) and this is the most digestible explanation I’ve ever seen. Incredible stuff bro!!!!
Literally, this is the most underrated channel on the internet. i just rewatched the reupload :D
🙏
Amazing videos, thank you!
No comment...
But much appreciation to you for the donation
That is a really brilliant commentary
This video increases my respect for interstellar even more. And even more praises to the creator for such a detailed explanation and calculations.
15:00 that's one of the most beautiful things I've ever seen, thanks for making me cry :(
🤢
If I am to trust the "uploaded x hours ago", then this video was literally uploaded within 30 mins of me finishing watching Interstellar. Timing literally couldn't've been better lol
Same thing here, just finished the movie for the first time, went to RUclips for more answers and boom, first video on my recommended lol. My phone is either blatantly spying on me, or I'm stuck in the tesseract rn 😂
I never watched the movie but everybody else in the Physics community seems to have watched it, so maybe I should "give it a chance"? 😃
@@User-jr7vf it's great! I thought it was cheesy as hell in the first hour or so but they get you hooked in around halfway thru
for me it was like less than a minute apart.. but on Miller's planet
We need this kind of channels that provide genuine Science education.
It's pleasantly refreshing to watch this kind of video out of all other channels that do nothing but stitch random space videos and pretend to talk and predict science.
This man deserves a standing ovation!
Glad to watch it again. I gotta say, nolan should have kept the black hole (and trinity test in Oppenheimer) as realistic as possible
Honestly he did even better than that. He portrayed almost exactly what it would look like 4 years before we even got a picture of it
Keep in mind it was a simulation of a black hole 4 years before an actual photograph of an actual black hole was taken, and the properties and phenomena of which have been revised subsequently. It is really impressive I must say.
Still I believe, he should've shown the Doppler effect which darkens the accretion disk.
The trinity test was so lame. I watched this whole movie waiting for this moment and you used some tnt? Was legit a moment when cgi would have been better.
@@TristanCleveland nah, imagine having such a terrible take like this
This is amazing. Thanks for sharing!
Kip Thorne, a renowned theoretical physicist and Nobel laureate, was a key scientific consultant for Interstellar. He played a crucial role in ensuring the scientific accuracy of the film's portrayal of black holes, wormholes, and relativistic effects, particularly regarding time dilation and gravity. Thorne's involvement helped bring a high level of realism to the depiction of advanced space phenomena.Kip Thorne initially worked with producer and director Christopher Nolan and his brother Jonathan Nolan (the screenwriter). He provided scientific guidance but also had a significant influence on the storytelling. Thorne ensured that the film adhered to the known laws of physics as much as possible, while also allowing for creative storytelling when necessary. For instance, he and Nolan agreed not to violate the principles of physics (such as faster-than-light travel), but they did allow for speculative ideas like traversable wormholes.
Kip Thorne’s involvement ensured that Interstellar is one of the most scientifically grounded science fiction films ever made, blending complex scientific concepts with emotional storytelling.

@@gazehounddead Internet theory isn’t true
'Wow I didn't know an entire paragraph with mostly good grammar was a ChatGPT comment!1!1!1'
yeah okay.
Well (same as last time) I'm glad I watched a commentary review about the realness of the visuals of a popular space movie.
Good work.
Thanks 🙏
I read the book Science of Interstellar a long while ago when it came out, and wow!! I'm amazed with the animations in this video!
Thanks !
I love that book! And it’s really cool to see the more realistic visualizations in this video too.
I also love that Interstellar was the first time a black hole was simulated in HD. They also had a room full of computers calculating and creating each frame, and even with that it took a long time to create the shots of gargantua.
While some of the things in the movie are a stretch (and a handful unrealistic), I appreciate how they made the move as close to plausible as possible (and I also get why and appreciate that they didn’t display gargantua realistically - it’s already a lot to take in)
@@andrewsanford I remember reading that interstellar, just like other nolan movies, had one of the heaviest Reels size and I'm not shocked by the amount of time and computation needed lol. Ray tracing all the frames with that resolution and hence the pixels is just phenomenal.
this video came out on my birthday-interstellar is my favourite movie and you are one of my favourite channels. i was so excited to see you talk about the physics behind it, and it made it even more credible that you relied on kip thorne's book. so thank you so much for this gift! ♡
Literally the best video out there I’ve watch dozens and dozens of these. The breakdown of the calculations with verbiage is amazing! Thank you!!
This was INCREDIBLE. Your simulations are hypnotic, your implementation of real physics and math is fascinating, and the way you explained it was so clear and easy to understand. The best video I’ve seen in a long time!
This continues to be my favourite RUclips channel. The visualizations are breathtaking now, but they are only beginning to catch up to the level you are on regarding knowing exactly how to describe things to your audience to bring topics into grasp which other educators have failed to breakdown in such an accessible way. I have learned so many things from you that I figured I would never learn without an in depth understanding of the math. Thank you so much.
Cooper's Station is by far the most unbelievable part of this story. Not because of its questionable feasibility, but because of the damn housing. This is a station clearly modeled after cylindrical space colonies dreamed up in the mid-century. Space colonies meant for alternative living around a still mostly livable Earth. Not interstellar arks housing the last bit of humanity clinging to survival at all costs. Why on earth would they waste valuable square inches on traditional suburban homes?
Otherwise, good one Nolan.
Considering that they have gravity control tech and have presumably been in space for at least a few years, it's conceivable that cooper station isn't the only space station humanity lives on at this point. Once you're already in space, with construction infrastructure and a large population, it's a lot easier to build *more* space infrastructure.
To be honest I didn't interpret the end of the movie as the humans leaving the solar system through the wormhole - why would they? There's no longer any rush or emergency. It seems more like humanity has stabilized as a spacefaring society and is now on the path to gradually spreading through the solar system and exploiting its resources as needed, eventually branching out to exploring Gargantua via the wormhole and other star systems via traditional interstellar travel.
@@washingtonirving8240 Bro it still doesn't make any sense. Making such stations would require a LOT of materials and would be EXTREMELY EXPENSIVE. Realistically it would all be very dense housing
Why on cooper station*
@@KalashDaCat The whole point of the end of the movie is to show that humanity advanced and AREN'T struggling for resources and survival dude
@@yossarian00 There is a huge difference between not struggling for resources and minecraft creative mode.
The quality of this video is just outstanding.
This video really made think of black holes, time dilation, gravity, spaghettification and more fore like HOURS.I wonder why this video haven't many views, it deserves more views actually. This video is really mind blowing and the stimulations, the calculations and everything need to be appreciated.Thanks for this video.
That simulation of entering the wormhole 7:37 , was really similar to the split scan effect in 2001, space odyssey, quite fitting lol
Yours is a unique channel, with the kind of a content that cannot be found anywhere else! Truly a treasure and yet freely available! Feeling grateful!
Criminal that this doesn't have more views when channels like Veritasium show that people enjoy physics content. RUclips sort out you're algorithm!!!
Amazing as always!
This video should be part of Interstellar extras, despite copyright violation . Excellent job!
What a marvellous video. Although all the maths go well beyond my head, your way to explain the physics in basic language allow us to understand the basics and visualise how and why things look in the way they do. Thank you so much for bringing this high level knowledge to the masses, your channel is great. I am glad I subscribed although just now I am rediscovering it.
what are the odds i literally just watched this movie (bawled my eyes out multiple times), and stumble upon this video
always love how well you explain everything
Thanks!
As a software engineer I love how you show the code that you used to implement the simulations. Very impressive.
In the internet where stupid fake science run rampant, you're one of the few who actually put in the work and educate viewers.
Kudos, subscribed!
Yeah man, in the internet one place people are getting money by showing there body and here many talented and educated person are struggling to earn bcz of society which is not focusing on them
@@BraddysReagent I totally agree.
this video needs appreciation not everyone can analyze and represent with stunning visuals with precision to help us understand the accurate concept
This video is incredibly underrated. It's one of the most remarkable ones I've ever come across on RUclips. The script, editing, and dedication displayed in it are simply enviable.
I haven't even finished this yet, but felt compelled to express just how amazing this video is. Everything, from the visuals to the explanations, and especially how seamlessly you weave them together is honestly one of the best visual depictions I've ever seen for content like this. Even the way you animate the equations and plug them into others, while not detracting from the visual simulations is just flawless 😮
Holy crap this video was WAY more interesting than I thought it would be. Commenting so the algorithm picks up this amazing content. Love your work, man
The way you simulate and explain is much more comprehensible any other videous on youtube. Your explanation with combination of spectacular simulations are realy fascinating stuff.
I'm late to the party here. I watched the film years ago but only saw this video now. What an incredibly detailed video. You should be helping to produce Interstellar 2 with your skills. This is amazing.
If they gave Nobel Prizes to science videos, you’d surely be nominated. Amazing stuff, thank you.
I had a feeling some details in the film weren’t accurate when I saw it, really glad you made this video doing all of the calculations!
One of the best productions to ever be produced on the platform. Well done!
15:00 - HOLY MOLY, this is what I came here for. Why did they not make it look like this in the movie. This looks spooky as hell :O
this video really almost took me into like another dimension
watching it on my room at dark,headphones on it almost travels you and it can be quite the small experience like a simulated one if you will.
Truly one of the greatest videos on youtube. Nobody in there right mind will go this far just for a video like this.
This is a true masterpiece, just like the movie itself! Would you be willing to share the black hole simulation codes?
Thanks
Thank you so much 🙏
@@ScienceClicENthis is the first of your videos I've seen, mind blown...
What do you do as a profession, if you don't mind me asking!?
Bench welder here.
This is seriously good work. Greetings from a fellow sci-fi appreciator from India.
hard to believe it's been 10 years already that this movie came out.
great job on the simulations and comparison with the movie scenes.
Videos like these the reason I like RUclips. The quality of the content is unmatched!
FOR REAL. Preach.
Your physics videos are just amazing. You make the toughest physics concepts understandable for everyone. You are not just a science communicator, but also a science influencer. The content you make and the aesthetic and everything is going to drive so many people in studying astrophysics. Love watching your content.
3:22 they would never fly the shortest distance, they would still have to follow an orbital path and it would be quite a bit longer
How about that. I absolutely love Interstellar, worked as a 3D artist for several years and now as a software engineer for the past four years. So this video is incredibly interesting to me, thanks so much. So cool to see the calculations and creation of the visuals. Oh, and to be honest I actually prefer your visuals over those in the movie.
what an interesting video!
This is one of the best things I've seen in 2024, absolutely great job!
This animation in this video is quite literally the quality that 10 professional animators, working together full time for 6 months, could only hope to achieve. And that's just the animation! The building, intriguing music, the dialogue, and most of all the brilliant explanation talent make this the most flawless educational youtube video I have ever seen. This is really an astonishing level you have achieved. If there were some kind of award with a prize for the most outstanding original RUclips video, this would easily win number one. You would have several other entries in the top 10, by the way.
2014???? It's already a decade ago??
That’s how math works yup
2024-2014=10
2014 is basically just 2024 but some stuff are not existent
On Miller's planet, only 80-85 minutes would have passed.
No.

The movie will release Christmas 2025.
@@JimStyslinger-hq9sq Yea but that would not be Hollywood like.
RUclips copyright system going at it again 😢
Amazing video, hope it blows up as it should.
I particularly love the visualization of the inside of the wormhole.
It think it looks so much more mesmerizing than the one in the movie.
Thanks a lot 🙏
Bro this video is insane ngl I want more content like this on my feed.
Amazing content! Thank you for the hard work!
My method for 'The Copper station' is that in the end of the movie, Copper gets a spaceship. For a moment it show us space relative to the motion of the station, and there we can know it's angular velocity. All what is missing is mesuaring that speed and R=g/w²
8:29 I didn’t know the DMV was near a black hole
Please please PLEASE include a music list! Your backing theme choices are excellent!

@@ScienceClicEN what is the name of your song during the wormhole section?
This was extremely good. The amount of effort put into this was astonishing. This deserves much more views.
Thank you for this video!!
i understand why they ignored some things for Gargantua, since a film needs to tell a story and be visually appealing, but i think the simulation with the other effects included looks way cooler and honestly adds to the "fear" factor of the black hole... it looks so alien and foreboding
Not only that, the fact that it looks "weird" raises questions in the minds of inquisitive viewers. At least some of them would seek answers to those questions, educating themselves on topics they would otherwise never touch. It was an anti-intellectual decision to remove all that. And for what? A flimsy "looks better" excuse. Everyone involved should be ashamed.
the reupload gave me an excuse to watch it again, great video!
Glad you liked it 🙏
3:15 I Think A More Accurate Approach Would Be 1.4 Billion km Instead Of 1.3 Billion km. Divide That By 2 Years In Hours And You Obtain 79.900 km/h, Or 49600 mph.
wow. just wow. makes me realise how much work the crew at interstellar did. props to you for making me able to appreciate the movie so much more than i already did.
I'm at 6:42 in the video and felt the need to pause and comment on how mind blowing this video is. Insane work.
What a terrifyingly beautiful visuals. Hats off to your effort for the rigorous calculations and simulations. Such a treat to eyes.
this was incredible! keep up the good work!
Thanks!
the music used in 15:03 is "Voyage à travers l'espace temps"
Absolute legend
@Mmogameable thx 😊
PhD level analysis. From one to another, well done sir
Love watching these kind of videos, just theories and calculations on such complex matters are oddly relaxing to listen and/or watch
Ah what happened to the original? Either way, the visuals, the explanations, all top notch as usual!
Thanks! I had to change the beginning showing a few clips of the movie due to copyright claims
12:01 Or the Black Hole would need to rotate at 299.792.457,999997 meters per second, or *3 Micrometers slower than the Speed of Light!*
Wait what? Is this a re upload? Edit: just saw pinned comment. This video was absolutely incredible btw
Thanks 🙏
This video is extremely well-made! I've never seen such a clear & detailed discussion of modern theories about what happens inside a black hole.
The math and visualization in this movie is amazing; and the fact that it is nearly all completely accurate is even more amazing
Repeating my questions from last time (with answers from scienceclic)
They would do a hohmann transfer rather than direct flight, but they had some martian and julian slingshots so a direct flight was an estimate for not absurd numbers.
The baseball's arc doesn't match it going into the simulated gravity of the other side of the toob.
By the way since your question I have calculated the Hohmann transfer for a Earth - Saturn trip and it is actually not that far from a straight line, both in the heliocentric frame and the frame which corotates with Saturn around the Sun. That's because Saturn is much further than Earth from the Sun, such that the transfer trajectory is a very elongated half-ellipse.
Could the planet Miller not be seen due to the extreme temporal dilation that would cause redshift out of the visible spectrum? (when the astronauts were far from it)
@@NeroDefogger are you okay man
Omg this isbthe best explanation i have seen on the Internet. Thanks for your hard work
7:30 I am struck by the fact that this isn't what the bulk of the wormhole looked like, considering how much it resembles the tesseract in shades. Your rendering is somehow more stimulating and exciting than the original.
Copyright ruining things again. Beautiful video also I think you should fight the claim.
I'm absolutely stunned by the simulation of the interior of the wormhole, and the reallistic simulation of Gargantua is just so beautiful (given I like blue a lot)
🙏
