- Interstellar was a blockbuster film and was loved by a wide audience. The incredible scientific accuracy of the visuals and plot are what differentiate it from others. However, it was not perfect and there were a few errors that director Christopher Nolan chose to include for specific reasons such as to avoid confusion, as well as adding imperfect human logic into the dialogue. Here are 5 Times Interstellar Got Physics Wrong.

Special thanks to the @samk9632 black hole tutorials. All animations and videos were made by me using Blender, Adobe After Effects, Adobe Premiere Pro, Adobe Audition, and Adobe Photoshop.
What always bothered me in this movie is that they needed an entire rocket to launch a small ranger from earth. But they could land and take off Miller’s planet WITH ONLY THAT RANGER and Miller’s planet is supposed to have a higher gravity than Earth.
That’s a pretty good point. I assume it was in an effort to save as much fuel for the mission as possible
@@howtheory Yeah earlier in the film before they left, Cooper mentioned that he was barely able to leave the stratosphere with the ranger he was flying at the beginning. This basically says that the rangers are capable of getting into orbit on their own but because they’re leaving earth, they would need the fuel on their expedition rather than have it be wasted just trying to dock with the endurance.
May be escape velocity of miler is very less
It wasn't about thrust. It was about conserving as much delta-v (fuel) as possible; hence why they used a rocket to send the it into orbit so minimal fuel in the ranger was burnt.
@@pranjal__0612 As he said, it’s not. The gravity is higher. Escape velocity directly correlates with mass.
I appreciate the "my representation" part. That really helped to build a nice visual and props to you for going that extra mile to make sure we can understand correctly, also just looks pretty cool
Thank you! I was pretty stunned when I first made it too. It’s my new wallpaper lol
@@howtheory yooo thats nice
@@howtheory I don't want to be disrespectful but I don't see the difference. Can you give me a hint?
I personally love Interstellar. It's one of my favorite movies of all time and I think it's story and themes are incredible. I usually get annoyed when people complain about Interstellar for not being scientifically accurate because I feel like they're missing the forest for the trees, but I understand it given how the movie was marketed.
Interstellar is a film with amazing visuals, amazing score, and great character work (in my opinion). I can see how the inaccuracies would bother someone who is more knowledgeable about astrophysics would be though. Interstellar always makes me cry every time I watch it, and I believe the heart of the film is not it's science but its heart, emotion and themes. The central theme of the movie is actually a very anti-scientific and fantastical one: The idea that the force of love can transcend time and space. Brandt pretty much states this theme directly into the camera at one point. For me it is one of the most beautiful movies ever made.
Your renders and visuals were super cool and I learned a lot from this video so thank you :)
high quality video. Im surprised you only have 1k subs wtf
Appreciate it man!
I didn't realize that it was only 1k wth
Exactly
He only has 1k because people would rather watch low-resolution 1 hour videos of spinning chips with 80s music instead of quality content like this.
@@howtheory Lil bro spend 1500 hours for 57K views 😭
5:47 The Gargantua with red and blue shifts made with Doppler physics looks absolutely breathtaking! Now I'm kinda sad that I didn't get to see this during the first time I watched Interstellar in IMAX, I can't stress that enough. Besides that, this channel is criminally underrated I can easily see it blow up in the near future if you keep making content of this quality.
Thank you, glad to hear that!
I saw it somewhere that they decided against it because it'd be too confusing for the audience.
@@lloydfeng5716 damn, kinda sad.
@@lloydfeng5716 That's really dumb, because I think it would have looked cool on the screen.
@@lloydfeng5716 I don't even understand how it could be confusing to someone. You can barely even notice the shift
Not only is the video incredible, you’ve definitely improved every single aspect that you’ve kind of struggled with just a couple months ago.. Fantastic job!
I appreciate the kind words! Your support has definitely motivated me. We’re all gonna make it brah
@Beyond you can always use epidemic sound for free and start paying for it once your videos get monetized. Most of the music I’ve tried looking for is not good on UA-cam and other places
All of these "faults" in the rendering of the black hole were pointed out by Kip Thorne. Nolan said that where the scientific accuracy conflicted with cinematic storytelling requirements they would go with the storytelling requirements, not the strict science. I think with the black hole visuals they made a mistake, as the accurate rendering with colour shifts and brightness differences is just as cinematic and even more impressive to look at.
This was everything 1 informative video needs: right visual representation of the stuff you're talking about, easy to follow (cause you explained almost everything with examples, related to the topic of video), not too long and boring, and all that made this video fun to watch, even to broader audience and not just science geeks. A like well earned.
Thank you!
I remember when watching a vid by ScienceClic on what its like to fall into a black hole, they say that a phenomena known as Aberration will effect how falling into a black hole actually appears. Essentially, fast speed you're traveling from falling towards the black hole will warp the light coming towards you, or lack there of (aka the black hole) to make it seem further away from you, whilst if you turn around and face away from the back hole, the light coming from that way will get magnified and things in that direction will look closer and take up more of your field of view.
Because of this, its actually difficult to know when you cross the event horizon, because you will still appear to be outside the black hole due to this aberration. This basically makes that whole scene where it shows him crossing the event horizon and then being shrouded by darkness not really accurate. If I remember correctly, the black hole will never take up more than half your field of view because of this, and just before reaching the singularity would appear as landing on a dark planet.
Amazing video, i was pretty mind blown when you showed the black hole much brighter and bluer on the side where material is coming towards you and quite dim and red where it is moving away. I never even considered this at all.
I had a a lot of fun making it too. I had never seen any good looking semi realistic examples online so I felt pretty good with the end result. Appreciate the kind words!
@@howtheory Space Engine simulates it well
Interstellar is a great example of real science being used to create cool images and concepts for a film, but artistic license still being employed to keep the movie palatable for the average moviegoer. Its always a compromise, but if it compels even a few ppl to become interested in the real science behind the fictional story...im fine with it
Great video 🤟
Imo the ending was absolutely awful and a total deal breaker. They should have shitcanned anne hathaways character.
How can someone "fall" into blackhole still alive and end up on their home's library? 🙄🤔
Annnnd here come all the armchair film critics to provide a critical rebuttal to something i never said.
To everyone who hated this movie...the comment section to vent your malcontents is that way 👉👉👉
Thank you for your cooperation
@@Nbomber and you are allowed your opinion buddy 👍😂
@@Agent-ie3uv Cause, he was guided there by future humans that knew how to make it possible. And, he is NOT in his home library, he is just manipulating the gravitational coordinates of that specific place.
It's like when you change some values at the memory of a graphics computer program to change a color in the screen. The effect occurs in the screen but the real change took place in the memory, something like that.
And, cause it is a fictional movie and you have to make some magic here and there.
It's fascinating that their depiction was so thoughtful, but still had enough room for error and variation that your depiction could be so visually distinct. I had always assumed that the nature of black holes was such that even significantly different one would be difficult to tell apart. This is one of those times where discovering I was wrong has made the universe even more interesting!
Actually really good render (probably the best fan-made render i've seen of the gargantua) and your claims make a lot of sense while also looking into any possibilities. Extremely underrated, should have over a million subs on your channel now. Normally don't comment much but damn this video was so good
A thing I learned not too long ago that really surprised me but makes sense is that, in some ways, black holes are a lot safer to be around than stars. It's just a big ball of gravity, and it's not nearly as likely to explode or burn you to death.
Yes, and a suitable accretion disc can replace some of the need for energy being emitted from the star too!
If you got sucked in by the black hole, you might change your mind
Maybe so but they are mainly safe if you are outside their event horizons and gravitational pull. If you have the misfortune of being pulled into the event horizon and are turned into spaghetti, it’s a wrap
I mean it would be real cold and very radioactive
OMG! “Your representations” part is so good! I have spent a lot of time to understand and rendering the gravitational lensing near Schwarzschild black hole, so I know all your masterpieces must spent really a lot of time to do! Thank you for your works❤! This video is really good😍
The physics, especially the time dilation calculations, for the movie was done by Kip Thorne - One of the great physicists of our time.
His books “Black Holes and Time Warps” and “The Science of Interstellar” are top tier books imo. Big inspiration for the channel
It’s super cool imo how much Nolan wanted the film to be as scientifically accurate as possible, so he consulted one of the greatest physicists ever, the nobel prize winner Dr Kip Thorne. I wonder if Dr Manns robot being named Kipp was just a coincidence
Your channel is severely underrated. Your work and visuals are awesome. Keep it up !
This is some high quality production my guy, keep it up!
you're definitely going places.
Gargantua with doppler looks astonishing thank you for the red blue render. Underrated channel
Wow your renders looked great! I really like the time and effort you put into this!
Bro how only 3K? This video was amazing and I stuck along the whole way through. Can’t wait to see more content.
Great video man, made me want to watch through all your others. That made me find the dimensional reflection video. It’s super interesting I’d love if you could release a part 2 as I see it’s been a few years.
Glad you enjoyed it!
Its insane how a video of this quality only has 8.2k views. Would love to see this channel grow!
Cool and so much needed! - I also want to give a comment in appreciantion, reciting Power Cosmic's comment!
> I appreciate the "my representation" part. That really helped to build a nice visual and props to you for going that extra mile to make sure we can understand correctly, also just looks pretty cool
Of course a movie, at the end of the day has to be a movie, be entertaining and not reflect a science documentary so it’s obvious why Nolan probably chose to ignore these details as I’m sure the highly paid physicist they hired wasn’t ignorant of these insights but it’s great to see such a high quality video that renders the scientifically factual image.
Exactly. All the knowledge from my video was obtained from the book written by Kip Thorne about the production of Interstellar. They were aware of all of the scientific inaccuracies and focused on entertaining the general population as opposed to adding unnecessary complexities.
its because its a shitty Hollywood movie
Watching this video was so relaxing, beautiful, funny, informative, and interesting. Keep doing amazing jobs like this. You will achieve many things !
Thank you, will do!
9:40 "Or doing what ever I don't care💀that would be much appreciated and stay tuned for the next video", that was the best outro I've ever heard.
Absolutely insane quality brother, you're gonna blow up soon.
Very nice edit ! Good job, i was just upset about how you explained the doppler effect which does not involves "energy" at all, but more about frequency
Fair enough. I just didn’t want to go too in depth on one principle
Most people don't realise that the Miller's planet scene was actually filmed on Earth!
Bruh how, where else could it be filmed
@@baccaracks Millers planet duh
😂
This was absolutely phenomenal! Great work!
How do you only have 1,9k subscribers??? The quality of your videos is amazing!
You don't need a black hole to spin at all to have a significant time shift from near the black hole to further outside, so it doesn't matter if Gargantua is spinning or not - the time slippage would be the same, however (sorry if I'm rude) you said that Gargantua had to spin a lot faster. No, it shouldn't. The time shift does not depend on an object's spin - mostly on mass (maybe some other tiny factors), meaning that the science in this part is pretty accurate.
Sounds like he's confusing the time dilation of travelling close to the speed of light with the time dilation of extreme gravity.
spin is a parameter of energy and energy absolutely plays a role in time dilation ua-cam.com/video/Z4oy6mnkyW4/v-deo.html
The spin is necessary to mitigate the gravitational gradient, which allows Miller's planet to exist in a stable orbit so close to the event horizon. The spin also accounts for why Cooper doesn't get spaghettified as he descends to the event horizon. Gargantua is meant to be spinning at very close to the maximum, but it looked a bit odd, so we turned down the spin to 0.75c in our simulation, which produced a smaller eccentricity in the shape of the shadow.
@@paulfranklin7161 Hello Mr Franklin, I am genuinely curious since you’ve come from a VFX background - have you always been well read in theoretical physics or was it due to the research required for the movie in which you acquired your knowledge? Love your work!
@@jamesdienow I have a fine art background, but I have always been interested in science. I watched a lot of science documentaries on the BBC when I was a kid 🙂 However, I learned a lot from working on the film, though I have to say the mathematics of it all completely elude me - fortunately my colleagues with physics degrees understood it which allowed us to collaborate meaningfully with Kip Thorne, who is a bona-fide genius by any measure.
considering how fast everything is moving near the black hole, fusion would likely be possible, depending on how close the material is to the BH.
The video I've been waiting for far too long! Thank you, man!
I really liked this video. Not just the explanation, but the quaility of the images is something to recognize
amazing renders man 🤯
Thanks man❤️
Another thing they got wrong (for the dramatic effect) is the scene where Cooper and Tars detach into the black hole. Thing is, they do it AFTER the burn that puts their trajectory into Edmunds' planet. This means that after detaching from Endurance, both rangers would just stay 'near' it on the same trajectory. To fall down into Gargantua they would need to slow down again somehow (so that their trajectory falls back into the black hole) and they had no fuel left.
This is so underrated I wish you the best of luck on growing your channel! I'm going to take maths, further maths and physics for A level to hopefully become an astronomer or astrophysicist because I find the universe so intense and amazing and I want to find out how it works!
Glad we share the same passion. I plan on uploading some videos relating to Einsteins special relativity in the coming months so I think you’ll like that. Best of luck!
You deserve way much more views and like! Fantastic channel! explanations are so clear!
Much appreciated, thanks!
2.79k- bro I really thought you have 1m for like 50% of the video💀 The quality is better than most of the 100k+ subs there hope you get it:))
Thank you!
was this channel planned? such high quality content and the fact that its so easy to follow is insane for only somebody with 1.9k subs? your extremely talented + great video
yeah im trying to be nice but jesus its true
The fact you're producing this level of content with only 4k subscribers is criminal. Can't wait to see you at 6 digits.
Very well done!! Learning something new every day. First video I have seen from you. I will be viewing others. Bravo Zulu!
I always wondered how Miller's planet would not be completely decimated by unimaginable radiation. Plus how could it maintain an atmosphere so close to a black hole, plus how could they survive the radiation on the surface??? But... I haven't seen the movie in over 5 years so... maybe they addressed all those things and I'm forgetting.
But thank you for this video- interesting stuff!
To stay in a stable orbit that close to a black hole, Miller’s planet itself must have a massive mass itself too doesn’t it? So the atmosphere is maintain by the mass of Miller’s planet itself.
Also the atmosphere is blocking most of the radiation, same as Earth.
@@tonamg53 Gargantua has an accretion disk which probably means that it's spitting out at least hundreds of times the amount of radiation the sun is emitting. With how close the planet is to the black hole I'd imagine it would take an absolute beast of a magnetosphere just to hold onto a semblance of an atmosphere. On top of that, our atmosphere doesn't even block all of the sun's radiation, with the sheer quantity of gamma rays, x-rays, and charged particles pummeling the planet even a relatively thick atmosphere is going to be insufficient I imagine.
The mass of the planet doesn't really matter when it comes to it's orbit if I remember correctly, mostly because Gargantua is just so much more massive than Miller's planet.
@@randomaster138 Size does not matter in space… its the mass that will determine how and what the planet is going to orbit…
If the gargantua has way more mass, then the miller’s planet will just going to get suck into it… but it’s in a stable orbit which can only implies it has enough mass to counteract Gargantua massive gravity.
Also when they are on the planet they are under the influence of miller’s planet gravity, not the Gargantua, so the time dilation is actually from the miller’s planet itself. Just like we are on Earth and its the Earth’s gravity that affect us, not the Sun (although the sun affect the Earth as a whole which pulls into a stable orbit around the Sun)
Also blackhole radiation is just a theory and no one knows for sure. By definition, black hole should not emit radiation as even light cannot escape its massive gravity. However there are some evidence suggesting that it does emit some kind of radiation although it is very weak. Most radiation that affect us that we know of, are from stars like the Sun which basically is a massive ball of un-shielded fusion reactor…
@tonamg53 While Hawking radiation is hypothetical, what composer and randomaster are referring to is radiation from the accretion disk itself. Spinning at such high speeds with so much energy that the accretion disk itself becomes a source of x ray radiation. Incidentally how the first black hole was discovered, Cygnus X1, invisible to telescopes in other wavelengths but a very bright emitter in x ray.
And.... that's not how time dilation OR gravity works either. They're in the sphere of severe time dilation around Gargantua. It's that simple. Why would a planet have enough gravity to cause such extreme time dilation? Time dilation around Gargantua as explained in the video, is due in part because of its mass, but most importantly it's spin. The rotation of Gargantua drags space time itself to that extreme, and the planet is orbiting within that region
@@tonamg53l that is required for an object to be in a stable orbit is it move fast enough to not fall in, and far enough tidal forces do not tear it apart. A planet can definitely orbit close to a supermassive black hole and not have to be massive.
fine I’ll watch interstellar again
Bro.. You already got sweet ass editing and narrative qualities for this video. Ur definitely gonna grow
Very cool man, enjoyed your work!
10/10 vid
The physics problem which bothered me the most was when the ring on their spinning ship broke off a big chunk, but it continued to spin around the original axis.
In reality, the damage would shift the center of mass, causing a serious wobble in the rotation, which would have made it impossible to dock with the ship's airlock--located on the center axis.
This was amazing! thanks for this piece
The most informatic intersteller video ever! for both movie 'Intersteller' as well as the real life one!
Can't complain, It is and will be the best movie of this century.
The social logic did not make sense either. As a society that had difficulty believing the Apollo Moon landings happened, how did they manage to accrue funding for a mission to Saturn to intercept a wormhole that would transport them to another galaxy? Not to mention they later build a colony cylinder in space within a human lifetime.
Because the people in charge knew the truth but wanted the population to believe otherwise. That's pretty simple to deduce.
@@cchavezjr7 Where did the money, resources, and labor force come from? Did “the people in charge” do it all themselves.
@@aliensoup2420 taxes obviously. NASA was in existence which most people thought was no longer. Why is it difficult to think that the government wanted the general public to remain focused purely on food production which was becoming scarce while secretly working on a side project that might save humanity?
Great quality on the black hole, and this video gave me knowledge.
Absolutely incredible work👏🏼🙌🏼
this is an insane video hope it blows up dawg
ay man the quality of these videos are amazing! deserves a sub. i hope you blow up in the future
you have way too little subscribers for a video this high quality.
you're doing fantastic work.
instant no second thought sub. I'll be watching everything you put out now
Point 3 - what light color would there be around Gargantua. It would actually be very light yellow, white probably if you are that close to it. And if you are far enough, it would be seen as orange and yellow. But it all depends on the filter you use to watch it. The human eye could not possibly look at it, since it would be like our sun and you would go blind
For Interstellar Nolan worked with Kip Thorne a Nobel prize winner in physics.
likely why nolan included brandt's incorrect argument about needing to go further afield was to show her desire to see if Dr. Edmund is still alive on his planet, since they had some sort of relationship back on Earth beforehand
Awesome work dude. Don't know what other content you make but you earned a sub :)
Much appreciated, more to come!
❤
Just seeing your channel for the first time, I like the way you went straight to the point no YT bullsh*t. You've earned a subscriber
5:47 Your representation was so beautiful it actually made me tear up
interstellar is one of my favourite films ever and i love how it keeps the science engaging for everyone, however, as nerdy as it is, every point in the video is well considered and completely valid, if not superficially, it appears you have an understanding of general and special relativity. The movie was kept palatable for the masses, yet for the nerds, there were touches missing. I believe Kip Thorne claimed for a planet to experience 1 hour for every 7 Earth years the black hole it orbited would have to be of comparable mass to TON-618 (65-70 billion solar masses last I checked, hence the general relativistic time dilation) as well as orbiting on the cusp of the horizon such that it's radial velocity was a significant percent of causality (hence the special part of the time dilation).

Great stuff in this channel. Thanks for all the hard work on this video. Like the movie, I enjoyed every second of this. Subscribed!
Great vid! Nolan said the reason why he didn't include the doppler shift was to make the black hole easier to look at by the common person and make it less confusing

Absolutly amazing work. I'm glad the movie somehow fell into my recommended ones and I didn't miss it.
That was beautifully made and explained, worth a sub
this is such a well made video for a channel with only 1.6k sucscribers, well done
Excellent ! Thanks for sharing, I did not noticed these mistakes (or choices).
I noticed another classical "Bad Physics" in this movie : the "Bulk".
In Interstellar, the space connecting the two 2-spheres of the wormhole is shown as a tunnel (to make things more understandable for the public). But the bulk connecting two 2-spheres, when you're inside it shows just as a normal 3-space. It is locally euclidian, globally it has 0-curvature all along the axis of travel between the two 2-spheres, and it has a positive curvature in any plane perpendicular to the axis of travel (if you turn 90° in any direction, you just come back to this axis).
Fom inside, the two 2-spheres are visible at each extremity of your travelling axis (you just see your destination and your starting point, distorted on each sphere).
The description of the outside of the wormhole in the movie is not that bad but not accurate (according to the theory) : depending upon the density of interstellar dust travelling through the bulk, the wormhole could appear as a more or less dark spheric object containing a second concentric sphere (the exit). At the moment you cross the first 2-sphere you see it exactly as a plane, and then its curvature is inversed : now you see your starting region in your back distorted as a big sphere, and along your travel axis you just see your destination point as a second 2-sphere...
This bothered me too.
@@Dominexis thanks !! We could add the problem of the Field continuity inside the WH (as stated in the Field Equation). Except on very rare configurations (2 extremities at exactly the same gravitational potential), any WH may be nice to see from the outside, but travelling through must be a one-way ticket : to come back the spaceship needs great amounts of energy to balance the difference of potential between the WH extremities...
@@fCauneau Though interestingly, it wasn't confirmed directly in the film that the wormhole was two-way. They alluded to the possibility of going back (since Cooper planned to return to his children), but nobody actually traveled *through* it the other way. Radio signals did of course, but I'd imagine those have sufficient energy to get through, especially considering that you could see all the stars on the other side.
@@Dominexis yep, you are right ! The way back trip is only envisionned by Cooper, and of course radio signals travel exactly like light : massless photons travel two-ways.
@@fCauneau It'd be another dastardly move by NASA in the film to lie to Cooper that a return trip was possible even if it wasn't.
amazing video man, seriously
1500 HOURS. INSANE! This video is genuinly amazing
thanks mate, really good video
amazing video !! keep up the good work
Thanks!
very detailled good job
Awesome video. Enjoyed it :)
this video title makes me chuckle you know that the director got Kip Thorne, a renowned theoretical physicist to help describe and calculate what a black hole would likely be, you saying hes wrong
the points made in video are based on a book written by Kip Thorne himself describing the inaccuracies of the movie. These are all thornes ideas.
