It always bothered me that time dilation only began once they reached the planet and not the whole time growing as they approached the planet and it’s proximity to Gargantua.

[@Laerei]

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.

[@neoncat6820]

They only spent a few minutes on the planet, meaning that in order for 23 years to have gone by, they definitely did experience time dilation in the hours it took going to and leaving the planet

[@Cylus1527]

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.

[@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?

[@bryanryan4504]

Would have taken several hundred million years to do.

[@dabigfreeze]

I guess it depends on how close they got and how fast they were going.

[@UrbanMediaReview]

It sounds like we just need to some how some way , some WHEN , enter a black hole.

[@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.)

[@miyannaable]

Your narration is simply and absolutely delightful. I am almost always thinking about black holes, even in the back of my mind when I'm doing something else. Sometimes magnetars. Black holes have transformed the way I see everything, and I often imagine that we are all inside one more massive than I could ever truly understand. For me, the best part of Interstellar was the moment he decides to brave the black hole.

[@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?" You will find many answers and new ways for you to actually understand what goes on. I would send the link but i think Astrum has disabled links as spam so i won't even try, ima let you put in the effort if you wanna know. ❤

[@christoffer886]

Why would it be different than orbiting a star if you exist in an orbit within similar gravitational "depth"? As well as if a planet has a magnetic field and atmosphere it would be the same as how earth blocks radiation from space and the sun.

[@SnakeKoRn]

[@SnakeKoRn]

@@christoffer886Depending on the distance tho, I think (but not sure) that the planet in Interstellar is too close.

[@georgemorley1029]

0:41 Yeah, the reason you got that feeling is because it IS science fiction.

[@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.

[@TyDie1]

I was thinking the same exact thing. I saw an illustration of the black hole and planet and the event horizon was well before the planet. So how is it still a planet?

[@DoctorX149]

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]

Is what true? It's all made up. There's no facts. Just some people making a hypothesis and their peers saying "yea we agree, our very basic understanding of mathematics seems legit enough to back up your science fiction story." Anyone jump into a big made up black hole to gather the info you claim you understand?

[@Simon-d]

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.

[@NightWanderer31415]

Absolutely true, the larger the black hole, the smaller the tidal forces.

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?

[@a.thiago3842]

Exactly. That's a point that i saw in one video some time ago. But it can teach you how relativity works and it's awesome. But it's a big mistake if seen from cientific eyes. After i learned more about this movie, the only thing real there is the black hole. Everything else is just simple theories that has not been proved that much as a blackhole. This way you can separate both sides of a coin

[@GrandHighGamer]

Well, the inverse square law does mean close enough to the blackhole there'd be an extreme time gradient. But yeah, if they're in orbit of the planet that goes out the window.

[@chrimony]

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.

[@tscoffey1]

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.

[@darkbeastzero]

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"

[@MikeMcCartney]

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. He argues that instead of a singularity you would have something like a 2 dimensional ring.

[@Grundrisse]

@@_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.

[@Grundrisse]

@@_BLACKSTAR_ Anyway, neither you nor him has bothered to read The Science of Interstellar to understand why Kip Thorne thought Cooper could survive the singularities and then construct a reason for why you reject it. You probably don't even know the types of theoretical singularities Gargantua harbors, or the type of black hole Gargantua is.

[@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.

[@dawesome_sauce]

Interstellar is a family adventure drama that uses a couple of intriguing bits of science to make for visually interesting set-pieces. Love the movie to death, but yeah, it treats science mostly the same way Hollywood in general treats science: a prop to do neat things on screen.

When I first saw Interstellar, my first thought of the tesseract scene was that it was a nod to the information paradox; the library represents all of the information that is thought to be lost when it enters a black hole. This could still be a secondary meaning. The Penrose diagram makes better sense of this though as it suggests that time and space flips orientation inside of the event horizon such that moving around in space is actually moving around in time.

[@lewis7515]

But it's not a library, it's only Murph's bedroom? The suggestion is that is how it might appear if you had limitless access to all instants of Time - relating to [I presume] a finite period of time - where focussed on that particular exact portion of Space....It's all only the same, one, room - not a library.

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.

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.

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

My interpretation, which maybe is wrong, is that the wave was actually a tide due to the rotation of the planet and the gravity of the black hole.

[@leftrom9738]

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.

[@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.

Wouldn't travelling between Miller's planet and back to the main ship require an insane amount of fuel due to the extreme gravitational differences?

[@hopeseekr]

No. Because when you're going out of time dialation, the faster-moving time decreases the amount of fuel you need.

[@jewymchoser]

​@@hopeseekr Really? To the planet and coming back? Getting out of our planet's or Sun's gravity well requires tons of fuel and the time distortion is negligible. FYI: I have no idea what I am talking about, just curious :)

[@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.

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

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)

Would the accretion disk not degrade as matter is eventually consumed and would it not require new matter to sufficiently power the solar energy these planets need to drive entropy in their systems?

Actually, in The Science of Interstellar, Kip Thorne states that the actual wormhole scene wasn’t accurate. The actual rendering wasn’t as exciting as the scene needed it to be, so the entire scene within the throat of the wormhole is creative liberty. “For the short, modest-lensing wormhole depicted in the movie, the trip was quick and uninteresting. For a long wormhole, it looked like traveling through a long tunnel with walls whizzing past, too much like things we’ve seen in movies before. … In the end, they were forced to abandon my wormhole equations and, in Paul’s words, “go for a much more abstract interpretation of the wormhole’s interior,” an interpretation informed by simulations with my equations, but altered significantly to add artistic freshness.” - Kip Thorne, The Science of Interstellar Also, in supermassive black holes like Gargantua, spaghettification happens much closer to the central singularity than the event horizon. However, anyone entering a black hole would hit an “outflying” singularity before they can reach the central singularity. This singularity is “gentler”, and wouldn’t have the same spaghettification effect. “However, the tidal forces grow so swiftly…that, if [the infalling or outflying singularities] hit you, they will have deformed you by only a finite amount at the moment you reach the singularity. … Because your body has been stretched and squeezed by only a finite net amount, when you reach the singularity, it is conceivable you might survive. (Conceivable but unlikely, I think.)” - Kip Thorne, The Science of Interstellar Lastly, the tesseract isn’t actually in the black hole, but rather in an anti-de Sitter space outside our familiar three dimensions that Kip Thorne refers to as “the bulk”. The inhabitants of the bulk, “bulk beings”, are the ones who created the wormhole, and they used the tesseract to pluck Cooper out of the black hole’s three dimensional space and into the bulk. “At the [outflying] singularity’s edge the tesseract awaits Cooper-placed there, presumably, by bulk beings.” - Kip Thorne, The Science of Interstellar The bulk beings then take the tesseract and move it through the compressed distance in four-dimensional anti-de Sitter space over to our solar system. “…the distance from Gargantua to Earth is about 10 billion light-years as measured in our brane (our universe, with its three space dimensions). However, as measured in the bulk, that distance is only about 1 AU (the distance from the Sun to the Earth) … So, traveling with whatever propulsion system the bulk beings provided, the tesseract, in my interpretation, can quickly carry Cooper across our universe, via the bulk, to Earth.” - Kip Thorne, The Science of Interstellar (Side note, you could play a drinking game reading this book. Take a drink any time you read “in my interpretation”) The time travel in the movie happens in our solar system as the tesseract intersects one of its three dimensional faces with Murph’s bedroom. “The back face [opposite Cooper] of the tesseract … is a three-dimensional cross section of the tesseract that resides in Murph’s bedroom in the same sense as the circular cross section of a sphere resides in a two-dimensional [plane] ... So everything in Murph’s bedroom, including Murph herself, is also inside the tesseract’s back face.” - Kip Thorne, The Science of Interstellar It’s hard to quote the book about the tesseract any further without including the referenced diagrams, so I’ll leave my explanations here. In short, the time travel stuff didn’t happen inside the black hole, traveling through the wormhole wasn’t accurately portrayed, and a traveler wouldn’t experience spaghettification in such a supermassive black hole.

In the end, Interstellar is more a science fiction based drama, and one of the freaking best. It’s about answering the question: “Who’s gonna save us?” “No one. Only we can do it. It’s US from the future”

To me the biggest confusion is why do we even discuss “entering” a blackhole, knowing fully well the temperatures and radiation around it. Its like saying what would happen if you land on a surface of the sun, will you be able to jump or play tennis etc. its all irrelevant because the moment you are close enough, you will be burnt to a crisp from the heat and radiation.

[@lasskinn474]

yeah - also maybe 80% of you would enter and another would get kicked out as radiation from the disc anyway.

From everything i have learned through science and philosophy i have come to the conclusion that time is already laid out Infront of us, this solves a whole bunch of paradoxes

[@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.

Interstellar has been my favorite movie for 10 years now. I can’t believe it’s turning 10 in 2024.

Repopulating the human species with Anne Hathaway sounds pretty good to me.
