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.

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?

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.
@@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)

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.
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.
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 TH-cam 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 😂
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.
Just wanted to congratulate everyone involved in this. If there's anything TH-cam did right, it was the fact that people like you are able to provide content like this to everyone else. This is massively appreciated and incredibly valuable. Thank you all!
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 😮
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 is incredibly underrated. It's one of the most remarkable ones I've ever come across on TH-cam. The script, editing, and dedication displayed in it are simply enviable.
Criminal that this doesn't have more views when channels like Veritasium show that people enjoy physics content. TH-cam sort out you're algorithm!!! Amazing as always!
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.
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
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
This continues to be my favourite TH-cam 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.
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 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! ♡
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
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.
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 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.
TH-cam 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.
This is the best video I've seen so far on the internet. Today I'm truly glad for being born in this generation and witnessing all of this valuable information for 🆓
I watch hours of science and Astronomy videos everyday and this video is truly one of the most breathtaking videos I’ve ever seen. The simulating black hole section is a masterclass of presentation blurring the line between science and artistic presentation that is mesmerising and deeply disturbing at the same time. Thanks to all who made this video possible.
I always trust your videos. You are my favorite science TH-cam channel and I aspire to understand physics half as much as you do in your profession. Truly, admirable
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.
I knew about the making of interstellar 7 years before the movie was released and I was so dissapointed when the movie didn't do black holes or wormholes right, you made my hope to see this come true! Thank you!
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 beleive that the biggest technical mistake in the movie is that the passenger that stayed in the spaceship, in orbit of the planet got much older than the two ones that went to the surface of the planet and returned to the spaceship. The time difference caused by the blackhole affect both in the surface and the orbit of the planet. The gravity of the planet itself is too small to cause that aging difference.
This has to be the visually insane video I've seen. Especially when you raytraced a black hole to show how it would visually look. My god, I can't even begin to imagine how it would look like being so close from within the planet. Absolutely phenomenal.
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)
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.
As I write this, it is NASA Black Hole Week 2024. We've already had (just last week, so slightly early) Veritasium (using some old 2021 ScienceClic footage) doing a video on black holes, PBS Space Time starting a small series on one aspect of black holes, and (on Monday) NASA Goddard showing a new supercomputer simulation of falling into a black hole. And now, on Tuesday, this. Twice. Including this comment, twice. (-: Followed by th-cam.com/video/WESb6MDXqkQ/w-d-xo.html which is just the simulations from this video without the mathematics and commentary.
Other information in now inaccessible comments on the previous upload that are of interest are ScienceClic responding, to my wondering, that it took 36 seconds to render each second of the simulation.
People also remarked in inaccessible comments on the way that the rough back-of-an-envelope sanity check of the journey time to Saturn, with its slingshot around Mars, was done. In fact, the movie makers only needed to steal from Arthur C. Clarke's _2001_ book for this. In that book the mission is to Saturn, does a slingshot around Jupiter, and takes several years.
@@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.
After 10 years and several viewings of the movie, I am still learning about the intricacies behind it, and people are still making content about this movie. Absolutely mind-blowing! Truly a masterpiece of a movie, and this video!
You have my respect sir... You always amaze us with your unique videos. As far as i know, you're the first, and I think the last, to analyze and simulate a scientific movie the way you did. No one would ever put such hard work to produce something like that. You have my respect again and again.
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
Veritasium's idea of physics is limited to thinking a bulb with lightyear long wire will light up immediately on press of switch. So let's keep him out of the big guys. Vsauce isn't a physicist, doesn't pretend to be one, he wants to understand and make others understand. He would just be super delighted with this video. 3b1b is a mathematician in core, also dabbles with physics - I think not because of physics but because of maths he is most definitely on par and at same level as ScienceClick.

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.
If they gave Nobel Prizes to science videos, you’d surely be nominated. Amazing stuff, thank you.
Literally, this is the most underrated channel on the internet. i just rewatched the reupload :D
🙏
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.

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 TH-cam 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
This video increases my respect for interstellar even more. And even more praises to the creator for such a detailed explanation and calculations.
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
Just wanted to congratulate everyone involved in this. If there's anything TH-cam did right, it was the fact that people like you are able to provide content like this to everyone else. This is massively appreciated and incredibly valuable. Thank you all!
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 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 😮
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 is incredibly underrated. It's one of the most remarkable ones I've ever come across on TH-cam. The script, editing, and dedication displayed in it are simply enviable.
Criminal that this doesn't have more views when channels like Veritasium show that people enjoy physics content. TH-cam sort out you're algorithm!!!
Amazing as always!
15:00 that's one of the most beautiful things I've ever seen, thanks for making me cry :(
🤢
This video should be part of Interstellar extras, despite copyright violation . Excellent job!
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.
The quality of this video is just outstanding.
Movie was released in 2014 and now it is 2024 (one decade) so only 1hr 25mins have passed in miller's planet
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.
Some other-dimensional being bumped a hyper-icosahedron into our bane.
The movie will release Christmas 2025.
@@JimStyslinger-hq9sq Yea but that would not be Hollywood like.
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.
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!
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
This continues to be my favourite TH-cam 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.
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 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! ♡
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
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!
Truly one of the greatest videos on youtube. Nobody in there right mind will go this far just for a video like this.
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.
One of the best productions to ever be produced on the platform. Well done!
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.
So underrated, can't believe we get to watch simulations that match movie standards in a youtube video that is also highly informative.
This is a true masterpiece, just like the movie itself! Would you be willing to share the black hole simulation codes?
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.
TH-cam 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 🙏
This is the best video I've seen so far on the internet. Today I'm truly glad for being born in this generation and witnessing all of this valuable information for 🆓
8:29 I didn’t know the DMV was near a black hole
I watch hours of science and Astronomy videos everyday and this video is truly one of the most breathtaking videos I’ve ever seen. The simulating black hole section is a masterclass of presentation blurring the line between science and artistic presentation that is mesmerising and deeply disturbing at the same time. Thanks to all who made this video possible.
Thank you so much 🙏
Please please PLEASE include a music list! Your backing theme choices are excellent!
Thanks! All the musics are my own creations, which you can listen to on my SoundCloud page (@aroussel)
that music from 14:37 - 15:48 was really amazing
@@ScienceClicEN but please really include a music list? or please tell me what music is this at 25:30 i can't find it
I always trust your videos. You are my favorite science TH-cam channel and I aspire to understand physics half as much as you do in your profession. Truly, admirable
That is a really brilliant commentary
I wasn’t expecting yt recommended to give such a high quality vid randomly but I ain’t complaining, the video was phenomenal
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.
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 reupload gave me an excuse to watch it again, great video!
Glad you liked it 🙏
This is seriously good work. Greetings from a fellow sci-fi appreciator from India.
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
Literally one of the highest quality TH-cam channels on the platform
Bro you can create your own Interstellar with this visuals. Outstanding work !!!
What a terrifyingly beautiful visuals. Hats off to your effort for the rigorous calculations and simulations. Such a treat to eyes.
This was extremely good. The amount of effort put into this was astonishing. This deserves much more views.
this was incredible! keep up the good work!
Thanks!
I knew about the making of interstellar 7 years before the movie was released and I was so dissapointed when the movie didn't do black holes or wormholes right, you made my hope to see this come true! Thank you!
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)
🙏
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.
Wait what? Is this a re upload? Edit: just saw pinned comment. This video was absolutely incredible btw
Thanks 🙏
Love watching these kind of videos, just theories and calculations on such complex matters are oddly relaxing to listen and/or watch
Copyright ruining things again. Beautiful video also I think you should fight the claim.
The attention to detail in this video is insane. You even visualized the frame dragging around the rotating black hole
Thanks!
Omg this isbthe best explanation i have seen on the Internet. Thanks for your hard work
I beleive that the biggest technical mistake in the movie is that the passenger that stayed in the spaceship, in orbit of the planet got much older than the two ones that went to the surface of the planet and returned to the spaceship. The time difference caused by the blackhole affect both in the surface and the orbit of the planet. The gravity of the planet itself is too small to cause that aging difference.
I think Romilly actually orbited the black hole from far, and not the planet, but I might be mistaken
This has to be the visually insane video I've seen. Especially when you raytraced a black hole to show how it would visually look. My god, I can't even begin to imagine how it would look like being so close from within the planet. Absolutely phenomenal.
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
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.
As I write this, it is NASA Black Hole Week 2024. We've already had (just last week, so slightly early) Veritasium (using some old 2021 ScienceClic footage) doing a video on black holes, PBS Space Time starting a small series on one aspect of black holes, and (on Monday) NASA Goddard showing a new supercomputer simulation of falling into a black hole. And now, on Tuesday, this. Twice. Including this comment, twice. (-: Followed by th-cam.com/video/WESb6MDXqkQ/w-d-xo.html which is just the simulations from this video without the mathematics and commentary.
Other information in now inaccessible comments on the previous upload that are of interest are ScienceClic responding, to my wondering, that it took 36 seconds to render each second of the simulation.
People also remarked in inaccessible comments on the way that the rough back-of-an-envelope sanity check of the journey time to Saturn, with its slingshot around Mars, was done. In fact, the movie makers only needed to steal from Arthur C. Clarke's _2001_ book for this. In that book the mission is to Saturn, does a slingshot around Jupiter, and takes several years.
This is the best video I've ever seen in this platform..A big salute to all the efforts behind this video 🙌🏾👏✨💝
15:25 is that you?
Well spotted, it is 😅
Ok like what is this channel and why am I just now learning it exists?? Everything on here is just mind blowingly good
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.
your black hole looks actually so much better then the one in the movie. Its much more grand and awe inspiring.
Watched it before, commenting to boost
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.
I just couldn't believe the credits when I saw them at the end of this amazing video. I expected at least 5 people working full-time on it for weeks!
the music used in 15:03 is "Voyage à travers l'espace temps"
After 10 years and several viewings of the movie, I am still learning about the intricacies behind it, and people are still making content about this movie. Absolutely mind-blowing! Truly a masterpiece of a movie, and this video!
This is so cool
Thanks!
Easily one of the most impressive things I've seen on youtube. absolutely incredible.
Mathematically to our knowledge this is the most accurate movie ever made
No it’s not
You have my respect sir...
You always amaze us with your unique videos.
As far as i know, you're the first, and I think the last, to analyze and simulate a scientific movie the way you did. No one would ever put such hard work to produce something like that.
You have my respect again and again.
Have a comment. It's the least I can do. Literary.
Roast roast
As others here, commenting for the algorithm, this is absolute perfect content
Just Shut up and take my money 🤑💰👍!!!
Loved every bit of Interstellar and of course also love literally every single video from this channel 🤓👌💯
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
Veritasium 3blue1brown and Vsauce are in big trouble
Veritasium's idea of physics is limited to thinking a bulb with lightyear long wire will light up immediately on press of switch. So let's keep him out of the big guys.
Vsauce isn't a physicist, doesn't pretend to be one, he wants to understand and make others understand. He would just be super delighted with this video.
3b1b is a mathematician in core, also dabbles with physics - I think not because of physics but because of maths he is most definitely on par and at same level as ScienceClick.
