Yeah, speaking in cosmic scales, the time dilation in orbit and on the planet would be so similar that there wouldn't be any percievable difference. Especially in orbit the ship is going in circles around the planet and thus experiencing stronger and weaker time dilation in equal measures thus nullifying any difference.

My main issue with Miller's planet is the characters' decision to visit it first. These guys are top-of-their field scientists who don’t take the time to do the math and realize that an observer on the surface would only have been there for a few hours/minutes. If they had, they would have concluded that the favorable report was only initial, and shouldn’t be trusted over the much more thorough survey of the second planet. They would also have known that for earth, it would be worth checking the third planet first, since any excursion to Miller's planet would take decades from Earth's timeframe. The point is that nothing about the time dialation at Miller's planet should have been a surprise to the characters. People like them should have suspected that phenomenon existed there, and they certainly had the know-how to mathematically check the potential consequences of going there.

[@larrywalsh9939]

Colonizing a planet in orbit of a black hole is unlikely to be a good idea simply because of the radiation present nearby, as their accumulation discs are incredibly violent - but other than that, if you live on such a planet, you're in a different timeframe than the rest of humanity, and while not entirely causally disconnected, it would inevitably turn into cultural disconnection.

[@jaymxu]

Wrong. You have a wrong image of a black hole, if the planet orbits at the perfect distance, which it would have to be anyway in order for us to live there, then it's the exact same thing, a black hole looks like a star to us, the disc is a visual representation of what they are, not of what they actually look like to us. The general visuals of this black ball with a warp of space around it moving like in space engine is not what they look like, they literally look like stars from the energy emitting around them and the hawking radiation coming from it. And the time only changes according to mass, so if the black hole was of the same mass as our sun, nothing would change. Plus distance, since a black hole the mass of our sun doesn't exist, it would be way slower there but we would be further away anyways, all our goldy lock zones are equal in time when speaking about stars and black holes. Because mass=energy but mass= gravity as well. Which meana whatever size something it, that energy will emit heat, which means the larger the further away, which in turn means faster time. Until ur in the habitable zone. Edit: lol people commenting to me saying the heat can be different but the radiation is not a factor since we would have to be at a further distance anyway, AND we still have amagnetic field either way. It evens it out. Y'all are funny.

[@jaymxu]

If you google this "How can a civilization tell that their "Sun" is actually a black hole emitting hawking radiation?"

​@@ZawaOnKZbinBut there is 100% a bootstrap paradox caused by time travel in the movie. Cooper is able to send information back in time to his past self that would lead him to the present, from his point of view. Cooper was in a place where time was represented as a physical dimesion so he could understand the 5th dimension, and you can see the paradox represented physically in those scenes.

[@BroadsideBob]

Two things regarding Miller's planet: (1) When Cooper et al initially left Earth, they needed what appeared to be a Saturn V rocket to rendezvous with the Endurance. However, when they left Miller's planet with gravity stronger than Earth (10% stronger?), they did so in a craft approximately the size of a small plane. (2) If Miller's planet was so deep in Gargantua's gravity well that it created some pretty extreme time dilation,. their craft would also not be powerful enough to escape the gravity well. I think there's a misconception about an event horizon: true, nothing, not even light can escape once past the event horizon; however you cannot just (figuratively) walk right up to the event horizon and walk away. Even well short of the event horizon, very very few things will escape.

[@playstationarusu]

Gargantua's gravity wouldn't make it any more difficult to escape the gravity of Miller's planet. The gravity well of Gargantua makes the gravity well of Miller's planet that much deeper, relative to space (and time) not bent by Gargantua. But relative to the space Miller's planet travels through, the planet isn't warping space any more than if it were orbiting a star or nothing at all. You are right though that a planet more massive than Earth would need at least the same or more force to escape. I don't think the movie explains that.

[@Maddinhpws]

@@playstationarusu I believe what he means is. If the main ship is parked in an orbit that makes for a much lower time dilation. While the time dilation on Millers planet is literally thousands of times more extreme. It is a matter of speed. To have such an extreme time dilation, the planet needs to move at almost the speed of light. Because even if it is the gravity causing the dilation, the planet needs to rate around the black hole several times a second to not be sucked into it. Which means for the scout ship to enter that extreme state of time dilation and to leave it again, it would need to speed up appropriately to close to the speed of light and back to not so close to speed of light again.

[@playstationarusu]

@@Maddinhpws Well yeah, obviously I agree that if a craft can't escape Earth it can't escape Miller's planet let alone a black hole. I'm just pointing out Miller's planet itself wouldn't become any harder to escape because of the black hole.

[@mopthefloorrr]

Well the black hole was obviously used by the future humans to help the current humans, so it would make sense they set everything up to work out for them. As well as the fact that black holes often randomly spit out light and what not from their outer horizon and orbit because of how unstable they can be. Overall i was satisfied with it because some of the weirder stuff was explained by the abilities of the higher beings future human people, who can obviously manipulate the universe to their will.

The first problem I thought of with the time dilation caused by the brief visit to Miller's Planet is this: If the gravitational change between the orbit of the main spacecraft, and the orbit of Miller's Planet is that extreme (20 years to 1 hour), how did the relatively small ship that visited the planet possibly have enough delta V capability to climb back up that gravity well?

[@Yinzermakesvids]

Hence the science fiction 😅

[@heyspookyboogie644]

It’s only a time difference relative to an outside reference frame. Meaning if it takes 20 minutes to break orbit, then it always takes 20 minutes for the ship/those on the ship regardless of the amount of gravity or time dilation compared to the mother ship.

[@heyspookyboogie644]

@@Yinzermakesvidsit’s actually not fiction. It’s how time dilation actually works. Like clocks on a GPS satellite only run slower relative to clocks on earth. 24 hours on a satellite still takes 24 hours to pass from its perspective. That’s why Cooper and Brand only experience a short time away vs the years Dr. Romilly experienced.

[@petrut.1224]

You're asking too complex questions. The ship would have been vaporized into oblivion as soon as it came closer to the accretion disk.

yeah they definitely "stretched" the amount of time dilation for going down to that planet and back. For the amount of gravity portrayed, the dilation should be a lot less, like maybe a few days (or even less) and not years. however, that would not "communicate" the efffect. "wow you fuys were gone for days". "actually it was only a few hours". "oh. ok"

I always thought the scene where he falls into the black hole was supposed to be the beings from the future teleporting him to the 5D dimension (IIRC the robot even says that the beings were the ones to show him the 5D world), maybe because the beings were supernatural in nature or maybe because the beings were future humans or sympathetic aliens who were able to save him using advanced future technology only available thousands of years in the future.

I always understood spaghettification as being a less significant issue with supermassive black holes, as the gravity increase as you get closer is more gradual over a greater distance than smaller ones. Is that true? That still doesn’t solve the deadliness of the hot plasma or the photosphere

[@pointofpersonalprivilege]

True, the point at which spaghettification destroys an object/ person depends on the black hole's size. While for a relatively small black hole it may happen even before reaching the event horizon, for a supermassive one like in the movie Cooper could fall for 99% of the way from the event horizon to the singularity before being spaghettified.

[@socalminstrel]

Great video. One nitpick: in a supermassive black hole, "spaghettification" would definitely not happen anywhere close to the event horizon, on either side of it. These black holes are so massive that the gravity gradient is very gentle until you get much, much closer to the singularity. Spaghettification near or even before the event horizon would be a serious risk in a stellar mass black hole, since it is a lot smaller and the event horizon is much closer to the singularity.

[@gamersvr6379]

I've been watching some Interstellar videos lately, I realized recently that Gargantua is supposed to be a supermassive black hole, containing 4 million solar masses or something like that, but when you watch the movie and you see the ranger in the accretion disc, you can actually see the circumference of the black hole, if it were truly realistic, once the ranger approached the black hole all you'd see was a black huge wall due to how big it actually is.

Kip Thorne gave a talk on the physics of Interstellar and his role in it, and he was asked to come up with a simulation of the wormhole transition scene. He did, but it was rather unspectacular, so Nolan took some artistic license.

[@ravingodd]

11:46 I've never been satisfied with "spaghettification will kill you". Assuming you were able to jump into an event horizon feet first, the inverse square law would affect your feet sooner/stronger than your head, sure. But it also affects spacetime as well. So rather than being stretched out to impossible thinness, aren't you simply following the path of least resistance? The outside observer, if there could be one, would see someone stretch. But to the person jumping in, they would remain intact, would they not? As you stretch towards the event horizon, so does spacetime, and you fill the same space.

[@TFDwolf]

Well...no. The problem is that you'll accelerate as you 'orbit' into the event horizon, which is when all of the matter in your body will begin to break down to fundamental particles as everything is accelerated to very near the speed of light. Time and space are relative, but the speed of light is the speed limit, and any object with mass will break apart into fundamental particles as it approaches it; or rather, the massless particles will keep accelerating off of your body while the mass remains (not for very long, mind you).

[@Wunba]

I’ve seen the movie 10+ times and it’s amazing but the one that always gets me is at the end when they orbit the blackhole that takes like 30 seconds in the movie. Perhaps there was a time gap, but wouldn’t you expect it to take ALOT longer like a year or something given the size of the blackhole?

[@DaddyHensei]

The blackhole itself was rotating at near the speed of light. With the amount of gravity, I’d reckon their own orbital velocity was probably similar. It also depends on perspective, if you were far away from them, they’d look to be going slower. Because well, time is relative. I have a bigger problem of them being able to avoid colliding with the accretion disk personally. It’s kind of hard to bullseye the event horizon even that of a supermassive black hole even with its weaker tidal forces. But wouldn’t have a movie then. Also when he fell in, he should have basically experienced the entire heat death of the universe with how messed up space/time would be. From Matt’s perspective, he should have, basically experienced all of time in a matter of a few hours of course this would be in total darkness. From what I understand. Basically, he essentially would have lived for trillions of years in mere hours. (That’s of course if he doesn’t somehow get stretched like a loony toon character.)

​@@DaddyHenseispace time is local. To someone entering a black hole, time would seem to pass normally (ie, you would fall in, spaghettify, and die within a few seconds/minutes/hours), but to those outside, the person would seem to be standing still for millennia.

Kip Thorne's written some brilliant books on the subject - one of the best is "Black Holes & Time Warps: Einstein's Outrageous Legacy" and another he wrote was on the science of this film which is also excellent. It's clear that one won't necessarily get spaghettified falling in towards the event horizon of a supermassive blackhole where the gravitational gradient is low enough, like those found at the centre of galaxies.

[@_BLACKSTAR_]

You can never reach the event horizon of either a stellar mass or a SMBH.Mainly cuz you will never find a SMBH without a very nasty accretion disc of ionized plasma whipping around at 50% the speed of light that would vaporize you shortly after contact. Even for argument sake if you could find a SMBH that had no accretion disc or charge and wasnt spinning at all, once past the event horizon you would be in spacetime that is falling faster than light, and the ionizing radiation would fry you almost instantly. Even if thats not true given the non locality of spacetime expansion, I think the exact opposite is happening inside the event horizon.I think the contraction of spacetime is extreme to the point where there is no more up down left or right, only one direction toward the singualrity and it would appear to be all around you and closing in due to the extreme curvature of space. But most certainly, once across the event horizon, that point in space becomes an event in your past that you can no longer return to and all possible futures lead to you hitting the singularity.Just like you cannot avoid next Tuesday.

[@paffles6696]

@@_BLACKSTAR_ Have you read a recent paper by Roy Kerr? It's too soon to speak of a scientific consensus but he makes a very compelling argument that singularities don't exist because the the movement of spacetime within and around a blackhole would be too extreme to allow for one.

@@_BLACKSTAR_ "an event in your past that you can no longer return to and all possible futures lead to you hitting the singularity cannot avoid next Tuesday" This sounds so familiar. Did you learn this argument from Viktor Toth? I suggest not consuming answers from him uncritically. He more appropriately fits into the category of a physics hobbyist who likes to write about his hobby, or a proper science communicator, rather than a top professional physicist. Toth has a history of watering down many of the physics concepts, like those of QM for instance, to the point where they aren’t simplifications anymore, rather they are incorrect assumptions unrelated the theory and the math it's based upon.

[@Grundrisse]

@@_BLACKSTAR_ Like, I recall seeing some answers by him in which he alludes to the common view that quantum entanglement is nonlocal, and so must QM. But this is quite wrong. Entanglement is natural, its absence would require explanation. It is a natural byproduct of having tensor-product Hilbert spaces. In fact, the fraction of states in a many-particle Hilbert space that are not entangled is zero. Moreover, entanglement does not betray locality (be it relativistic or nonrelativistic). It has been proven that quantum is local. It's just that people have not known how to think about locality with measurements until this paper comes: Locality and error correction in quantum dynamics with measurement by AJ Friedman. But tbf, it's a recent paper, so these facts are hidden to both the physicist and the layman masses.

It was a massively rewarding experience for me as I love physics, and working with Kip was just brilliant. Oliver the lead scientist, the rest of the team and I, all worked really hard on getting things right; As part of my work I rewrote a pathtracer called Mantra to work with the 'relativistic' pathtracing libraries we created so artists could use the software called Houdini with the Dneg renderer directly, that was great fun. All this work has directly influenced my current project called Aten7; it's a 'Culture' style sci-fi based 100 years in the future and is hard science based, specifically so that it helps create discourse and education in STEM principles.

something that's always bugged me in this movie is just how extreme the time dilation difference actually is. if the ship is in orbit of the planet, or even just somewhere nearby, and the landing craft goes down to the planet, then they shouldn't experience time that much differently, because they would both be about the same distance (relatively speaking) from the black hole, right?

Actually, spagettification not happens with every black hole, only smaller ones. Bigger black holes has smaller degree of gravitational change per distance, so the pulling force is more even.

no it would still happen it all depends on how far you are from the singularity. You wouldn't notice any significant spaghettification until you are near the singularity. The way the math works the event horizon for larger black holes would be no where near close enough for the spaghettification to happen unlike a stellar black hole or other dense object FYI you are technically experiencing spaghettification right now. the earth gravitational pull is stronger at your feet than your head assuming you are standing/sitting up. its just that its not strong enough to rip you apart

Great video. Regarding the closing of the "throat" for the wormhole, I do not fully agree with you. You suggest that traveling through a wormhole would cause it to collapse due to gravitational forces. However, if we consider a future advanced civilization capable of creating a wormhole, they would have already utilized exotic matter (in this context, we don't know how) to establish and stabilize it initially. Therefore, the issue of stability during travel is irrelevant. The same technology and exotic matter that created the wormhole could also be used to maintain its stability, allowing safe passage through it. In this context, an advanced civilization's ability to keep the wormhole open would negate the risk of collapse during traversal.

The problems with the planet orbiting Gargantua were: a) The distance between orbit and planet-surface is ridiculously small (compared to planet-back hole distance) for that time-dilation to have happened, in that extent. Even then, the crew should have taken this time-dilation into the account, which brings us to b) b) The most valuable resource was time (Earth was dying, year by year). Decades passed because they went down on the surface; time that Earth didn't have to spare. I remember thinking the above when I first watched the movie, and it stroke me as pretty stupid; it still does. For all the scientific research that was embedded in the movie, this is by far the most silly dramatization thing.

Paradoxes only work when you’re looking beyond their timeline. That’s the way you’re meant to view them (imo).

[@larrywalsh9939]

The notion of chronological paradoxes stemming from time travel might be based on faulty reasoning - if you were to go through a time portal to go back in time to stop yourself from going to the time portal, you theoretically have not created a paradox, because you already DID go through in your personal timeline. What you'd be doing instead is interfering with the path of the timeline of a different version of you. It would only create a paradox if that action altered your own past, i.e., events that you had already experienced, which is not the case here, according to the Many-Worlds interpretation of quantum physics.

[@Dziki_z_Lasu]

The Copenhagen interpretation explains perfectly all paradoxes in the film. As it is a film and we are observers of the single time line other realities collapsed after the first interaction from the future, so the appearance of the wormhole, forcing the loop to be completed. It doesn't deny the existence of free will so you can always make a googleplex (rather a smaller number because of Planc time) films with different scenarios, probably mostly about corn farming. Edit: After rethinking other decisions up to delivering the last crucial message had no importance. They were just making a reality with the wormhole appearance not existing.

[@Dasni12]

Like what they did in avengers endgame

[@TFDwolf]

It is based on faulty reasoning, but not the one you mentioned. Space time can flow at different rates, but it never goes backwards, and is always locally consistent. Even if portal 1's local time is twice as fast as portal 2 (the exit), it doesn't mean that you've gone back in time. Say you leave portal 1 at 10am, spend an hour at portal 2 and then head back to portal 1. Since you spent an hour at portal 2, it's actually 12pm at portal 1 when you return (because time moves twice as fast there). But there is no situation where you can leave portal 1, then come back to portal 1 before you left. It "seems" like you go backwards because the clock has changed at portal 2, but that's because their flow of time is totally different, not that it is ACTUALLY in the past. Think of it this way: if you go to portal 2 and then try to walk back to portal 1, space time will speed back up as you approach, and you'll once again arrive later than you left.

12:35 - a few corrections: 0) I think this is meant to be a photon sphere, insthead of photosphere (which is, basically, a surface layer of a star and has no relation to black holes) 1) photon sphere is not located at the edge of the event horizon, in fact it is 1.5 times further from the center (in terms of Schwarzshield radial coordinate) 2) the orbits of the photon sphere are unstable, which means that no photons get captured at this distance. on the contrary, they are being repelled from this region of space (the one's with the lower impact parameter fall inside and follow beyond the even horizon, while the ones with the larger impact parameter escape outside to infinity) 3) consequently, the light does not accumulate around the photon sphere, so no spikes of radiation would be observed, in the opposition to what is stated at 13:09

[@TheTamriel]

When Cooper passes the event horizon of Gargantua he doesn't get spaghettified by the singularity of the black hole but ends up in a 4-dimensional tesseract (a cube within a cube), presumably created by bulk-beings (who are likewise responsible for the stable wormhole near Saturn) as intersection b/t a higher-dimensional bulk and the 3-dimensional Universe.

My issue with the grandfather paradox is that it assumes time is linear relative to humans. What if what we call 2 timelines: A - Cooper goes to blackhole B - Cooper stops himself from going are just two parts of the same sequence AB which in this case would just be repeating ABABABAB since each sequence would have for consequence the next. From a human standpoint it doesn’t make sense because we think of A and B as two separate timelines that have to have an end chronologically greater than its beginning, but nothing says time has to abide by those rules. To time, it’s possible that AB = C (a single timeline)

[@hopeseekr]

@@jewymchoser The equation for fuel required is a combination of mass of the ship, gravity of the planet/star, and time. If time is massively dialated, so that 1 hour on the surface is like 10 years in near orbit, it means that time is drastically reduced in the equation the more you go up into space, thus requiring less fuel. Basically, it assumes the planet was already relatively less dense and most of the gravity we witness is from the pull of the black hole (thus the massive waves).

[@hopeseekr]

The waves are massive because, in part, they too are affected by time dialation. At 10 years to 1 hour, you can assume that at the top of the wave, time is moving substantially faster than at the bottom of the wave, resulting in less "effect of gravity", thus super tall.

As a movie in general: the story is not my cut of tea with a lot of plot holes (unrelated to science), acting was ok, music was good, science was lacking as explained in the video and even though it was consulted by Kip Thorne.

What's your math?

[@arminius1453]

5:21 so, in the movie, they should have solved the gravity equation before even launching, before even the lazarus missions, otherwise they wouldn't make past the wormhole.

[@JustaGuy1250]

regarding the paradox thing, i feel like time is something that is already determined. like, if cooper decided to not transmit the coordinates, then he would never have been in space to begin with. But because he is in space, he transmits the coordinates that sends his past self to space which in turn, will transmit those coordinates. It's a set in stone way that time works, even if you think "well, now i am not doing it anymore".. well, that's fine, time already 'knew' you'd think that.

Getting out of the gravitational well would take far more energy than the ship could possibly have.

[@KiloShank]

A buddy of mine showed me this film, and I tried to explain that at the point that people would experience greater time dilation from a black hole than they do an orbiting body around a black hole that they would be overcome by that black hole's gravity so much that they wouldn't be able to stand on that body.

[@LearningFast]

If Gargantuan was that massive then gravity would have crushed the people who were standing on it. That part makes no sense at all.

[@gamingscrub41]

Interstellar is the reason I went back to college and am currently pursuing my masters in astrophysics. So I owe a lot to this film and what my life is hopefully going to be like in the near future.

[@RaptorCakes]

This movie happened to come out when I was studying physics in High School and was actively reading Steven Hawking’s The Grand Design after reading Brief History of Time. The fact this landed itself right smack dab when I was considering being a physicist was nothing short of perfect timing. It was so validating for me to not learn about some of the visited concepts from the movie, but go in and recognizing the concepts as they were shown or described. I have a mind-gas. But funny enough, it was actually Hanz Zimmer’s soundtrack that really stuck. It was the first film sound track that just… rung with me… Long story short there, Hanz Zimmer, Nolan, and Interstellar is the reason I became a Sound Engineer instead of an Aerospace Engineer. It was something along the lines of, in one career, I could hypothetically figure out how we have or could live a thousand lives.. But in the other, I could absolutely live a thousand lives and moments. Creating the emotions and feeling like I’ve lived them became more so inspiring than Feeling emotions and feeling the want to live them, but never getting to. I enjoy physics as a delicious hobby side dish, but Psychology and Sound & Music have become my passion.

[@cjshardcorepunkmusicvault8474]

What makes Interstellar a stand-out in the sci-fi movie realm is that has a mind warping story line with not an alien in sight. As in real life, if we were traveling in space.

[@tomassoejakto]

My problem with Gargantua is how small it is. If Cooper is close enough to surf along its accretion disc, we wouldn't even be able to see Gargantua's shape; the screen should only be filled with black or plasma or both.

[@Ligmaballin]

Going into a black hole I think would be just as terrifying as it is beautiful. But if i had 1 more day to live and decide my fate, I'd probably would wanna go inside a black hole, it's just so ethereal

[@davesworld7688]

It was a fun movie. However… The “science” portrayed in Interstellar was downright ridiculous. As mentioned here in this video there is no way a human being (or really anything for that matter) could even get remotely near a black hole without being pulled into it then obliterated by heat and gravity that is beyond comprehension. But hey, it atleast taught kids about the concept of Relativity and how time is affected by virtue of gravity’s extreme pull.

[@user-jm4nj7nz6t]

I'm glad someone has finally called out Interstellar for its absolutely absurdities. Everyone raved about this film but the ending makes me want to puke. "Love" being the universal transcendental force, give me a fucking break.

[@GSXK4]

Our universe is in the center of a black hole right now.

11:59 "Slowly". We're still talking about literally the smallest units of time. In this smallest possible amount of time his legs travel at about the speed of light, while his head has, like 70% of that speed

No movie, music, or any other form of media has ever opened my eyes more to the need of being a parent who is present and available for their children. I was ugly crying at the end.

[@s4098429]

Why should there be time dilation between characters on the surface of the planet and characters in orbit, yes there should be dilation between being on the back hole and being far away, but that’s not what happens in the movie. The gravity of the planet is not strong enough to take decades away, only the black hole. You should have mentioned that.
