I can’t get over how amazing Interstellar was as an experience. Still to this day, no other movie had as much of an impact on me than it did.
2001 was the last year that Hollywood produced a good film
Really? I was a bit underwhelmed. I thought the pacing was poor, the characterisation wasn't great, the tension was so-so and the acting wasn't great. Decent cinematography though and some of the concepts were nice. But, you know, good you enjoyed it. For me it was okay, flawed but there were positives to take away.
Interstellar made me feel small, because in the vastness we really are. One of my top five favourite films.
I've seen Every Nolan film in IMAX since Inception and they've all been amazing movie-going experiences. Interstellar, Dunkirk and Oppenheimer are the top 3. You know they're great when you go back multiple times to see them!!
i watched it on acid once and now every time i rewatch it, i'm forced to tears at every high energy scene
I think what i enjoyed most about movies like Interstellar and Gravity is that they make space very dangerous and creepy. No dramatic killer aliens involved.
That's bcuz the universe is dangerous. Not necessarily creepy, but EXTREMELY dangerous. Yet eerily so incredibly beautiful.
@@ricaivory6571Honestly the thought of the aloneness and time travel you could experience sounds unnerving and creepy in some ways even though it's hauntingly beautiful.
@@theflowerhead you're scared but you wanna fly thru a supermassive black hole just to experience it.
Dont dare compare the Gravity trash with Interstellar
@@ah6169 it's not a crime to like both.
I was very sleepy when this was recommended to me and I thought it said "The Truth about Orangutans" and my half-conscious mind believed there was some conspiracy regarding the existence of Orangutans.
STAY WOKE
They literally look like dudes in monkey suits I wpildnt b surprised
lay off the pipe dude
There is a conspiracy , they don't want you to know the truth . Orangutans are sneaky and have a dark side...... ( cue haunting creepy music )🎶 🎵 "
Lmao
I can't believe this movie is already 10 years old! It's one of my favorites!
ikr.
Time is like that.
Literally watched this for the 1st time last weekend. Not sure why i wasted so long but damn was it worth it
it's 1 hour and 26 minutes in Miller's planet so not that old :)
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.
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.
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
What bothered me was that in reality, that level of time dilation would be on the very edge of the black hole itself, and a planet at such speeds would be decimated by the gravitational shear. They would have lost a few hours or days, not decades.
@@neoncat6820 not a bad assessment, but on the surface, where Cooper asks Brand how much their delay would cost, she replied, ‘decades’.
I always assumed the Endurance was put in an elliptical orbit around Gargantua, dropping off and picking up the lander as it passed by Miller's Planet but spending most of its time at a significantly higher altitude.
Interstellar was one of the catalysts, that piqued (not peaked) my curiosity about space and time. Yes there are plenty of inaccuracies, but it's still a very powerful and beautiful movie
Yes, this movie gives me a very haunting sense of loneliness.
"Powerful and beautiful", and curious and inspiring it might be, but the bottom line is: Interstellar is a stupid person's idea of a *_smart_* movie.
@@bluceree7312 yes and no. I truly doubt that human kind will ever understand the whole complexity of the universe/multiverse. This movie is created for a wide audience. Maybe some rando gets so deeply fascinated with space, that he/ she will make the next huge breakthrough in that field.
@@bluceree7312 Aren't you just so edgy and intelligent.
Advanced beings from the future send a message back in time to certain heroes to put them on the right path so that the future will end up as it already was when they sent the message. Interstellar or Bill and Ted’s Excellent Adventure?
The time paradox mentioned at the end miss states the film’s plot. He doesn’t communicate the equations to his past self to let his craft leave earth. His craft leaves conventionally and is already built when he arrives at the NASA base . He communicate with his daughter giving her the equation so she can develop the ships that will lift all of humanity off earth to seek out the new planet, which she does as an adult while he is away off planet.
True, it's still a paradox though since he never would have gone to NASA if it wasn't for him sending the message to his past self
@@neoncat6820If humanity never escaped earth they never would have been able to provide the wormhole from the far distant future. If they never had the wormhole, they never would have escaped earth. Time paradoxes are pointless to argue about.
@@GuyN0ir indeed, this specific paradox is called a bootstrap paradox, in which an event which shouldn't be able to happen is caused by a time travel which only happened due to the event.
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?
Hence the science fiction 😅
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.
@@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.
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"
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.
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.
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. ❤
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.
I would assume the radiation to be extreme
@@christoffer886Depending on the distance tho, I think (but not sure) that the planet in Interstellar is too close.
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. Because of the time dilation, those thousands of years would've passed already.
Agree. I think the point in the movie was that advanced humans from the future intervene.
Yeah, Cooper and tars were brought into the wormhole by humans very far in the future, when they've evolved past the 3 dimensions we know.
not sympathetic, if they didn't do it a paradox would've happened
It was indeed advanced humans, they opened the original wormhole as well (it's implied)
@zentrocs That's what fun about closed time loops, I mean they have to start with SOMEONE'S conscious decision right? It's mind blowing to try and think about.
I adore this movie, it's probably in my top 5 of all time. Black holes have fascinated me ever since middle-school, so this movie's beautiful and terrifying portrayal of it was amazing.
I agree, definetly in my top 5. The music is incredible and really adds to the movie. The "it's not possible. No, it's necessary" scene is a masterpiece all on its own.
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
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?
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.
Absolutely true, the larger the black hole, the smaller the tidal forces.
@@Simon-dagreed with everything you said (though I thought the bh would have to be significantly larger even than Gargantua).
It's all a theory. So if it sounds smart just go with it. There's no one that can say you're wrong. For all we know there's just a star there so big light can't escape
This video 10 years late because of time dilation
😂😂😂
Nah, it was the gas my bum released.
Aww now people arnt allowed to talk about things
Its a joke lmao @@michaelmohler5409
Or 10 years early
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.
6:14 should note here that Kip Thorne said that the scene of them going through the wormhole was extremely unrealistic. There's an hour long presentation of Kip explaining the science behind the movie on the channel 'Science & Cocktails' where he shows what the transit would actually look like.
Not only does he show what the transit would have been really like, but also answers SOOOO many more questions I had about the movie and explains the science behind it in such an amazing way that I love the movie even more than I did before! Watching it again tonight!! Go watch that video, everyone!
*Actually?* _Theoretically!_
He also did a book on the whole thing.
imagine a black hole being next to uranus... oh wait
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.
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.
@@_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.
@@_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.
@@_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.
@@_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.
I had a falling out with an old friend years ago. He loves watching Astrum and his favorite movie is Interstellar. While what happened between us is irreparable, I will always appreciate the positive impact he made on my life when I needed it most. I hope you’re doing well, buddy. Enjoy the video 👍
Women always come between good friends.
Honestly im tearing up a bit. Life sucks man.
@@Hugh-Janus69420are you the old friend??
@Sylar-451 i am not.. but i am in a very similar situation. My old best friend knows i love interstellar and astrum. But he wont talk to me. Ive tried for over 2.5 years to reach out and just het ignored
If you guys were my friends I would have stopped talking to you as well. Get a grip
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.
Being on the surface of the water planet would be no different than being in orbit of it, since there would be very little difference in the distance to the black hole's event horizon, so time wouldn't be going any faster on the surface than it would be for the ship in orbit.
then please watch the movie again and you will see, that the ship in orbit is in an orbit around the black hole. farther away from millers planet, not in orbit around millers planet
@@FuSoR1 I couldn’t remember, but I thought that might be the case - so in that case that lander has an absolutely absurd fuel supply, since it can not only land and take off and get back up to orbit without refueling, but even leave orbit. Absurd.
@@larrywalsh9939 Why you care? It's sci-fi movie only by advertisement. In reality it's a fantasy movie. You may listen to movie fans on fandom, I recite "Considering the blight is a mere plot device, it could be seen as a parable of the hardships faced by humanity in its History". In short, even fans of this movie understand impossible things are happening and it has nothing to do neither with science, neither with sci-fi.
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.
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.
I would like to see a video on the prospect of capturing a meteorite, putting it in orbit and mining it. I think there's a lot more to the story than just the technical aspects of it. The politics of this sort of endeavor would be an interesting subject. I believe some people would be apposed, fearing the possibility of it hitting earth as well as ownership and many other things.
mining asteroids or meteors is practically useless, and non profitable for any firm, whether govt or private. Its just not worth it. The economics and finances would never balance out, and it would not profit anyone at all.
Oh a For All Mankind video? Great idea! I'd want him to break down the season 2 ending. That ending got me in the feels real hard. For All Mankind and The Expanse need some Astrum breakdowns!!
how about a large enough asteroid hitting our moon causing it to change orbit enough to cause Earth changing phenomena, like the tides rising much higher than normal henceforth.
I remember reading about some of the theories of black hole and I really liked the one where, as you crossed the event horizon you were no longer falling in space but you are falling in time. Minus the obvious issues with that theory, i think it’s quite beautiful when you think about it. The light crossing the event horizon can’t leave it because it’s no longer in your time. But constantly moving to the future.
Can't wait for part 2!
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.
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. It reflects the same environment, over time - which means the same one wall, of the exact same shelving, and the exact same books that were ever on there - but only those exact same books.
@@lewis7515tbf, I don’t see how it’s impossible for there to be an infinite amount of these libraries of specific places in space throughout time
I would absolutely love to see a second episode on this beloved film! Yes, it got a lot wrong, but those make excellent points for you to explain how it works according to current theory.
this is part 1 so naturally we can assume its coming
Interstellar is my favorite movie of all time and my inspiration for cinematography. It is nice you made a video about it. :)
Yah it’s up as one of my favourites. So many times, maybe 100s, After a bender weekends, this be the movie to relax and sleep to, with the Hans Zimmer soundtrack, hardly ever saw the end. Love it
The photon orbit in the photon sphere (not photosphere) is unstable and photons can leave the orbit by either gaining or losing energy. If they gain energy, they escape out of the orbit. If they lose energy, they fall in.
It doesn't matter how spectacular your production is if the writing just isn't very good. I enjoyed some aspects of Interstellar, but the trope of "I was able to go back in time with the info needed to save to world!!" is boring and has been done over and over again. It didn't work here, it didn't work with Arrival.
Nah Arrival did it better.
the planets of interstellar are soooo cool. pls do talk about them. Also, in the past, I responded to a question you had about whether or not you should make content on more than just our planets etc. and I confirmed. I shortly after stopped clicking on your videos but not definitively as a result of your content. I do hope your channel has only grown since then. I've learned so much info I love from you and even shared it with friends who came to love your space stuff.
Thank you for doing a video about Interstellar! It's one of my favorite movie ever, but I can take it if it's not scientifically sound, it's just cool to know the real science behind it. A time travel show I really liked as well is Travelers, which imho got cancelled way too fast. They had a time machine and the AI watching the timelines and they'd have new Travelers arriving, giving glimpses of what their actions had changed. I really wish that show would have gone on a few more seasons, I would have loved to see where they were taking the story. On Star Trek some of my favorite episodes are the time travel ones and the mirror universe ones, so I'm always happy to find a video that explains more about the science, or fiction, behind it all.
I love black holes. I think they are the most fascinating objects we know about. I find with most things in nature, the more beautiful a phenomenon, the more deadly, or vise versa. I just can’t wrap my mind around the physics of how they work. I love the fact that the first ever photos of a black hole were published on my birthday. April 10, 2020.
🕳
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.
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.
Like what they did in avengers endgame
Love your content and I was super excited to see you make a video on this. Interstellar is my favorite movie of all time. This is truly Nolan's masterpiece along side The Dark Knight.
Amazing video once again 💖
It's one of my favorite space movies other than Event Horizon. But with Interstellar I felt like I traveled with them.
Thanks for making this video explaining the accuracies and inaccuracies of the movie, and delivering it in a rather gentle language that doesn't make me feel like I was being called stupid for believing in inaccurate information about reality; It has certainly made me more curious about the subjects brought up in the video and I can't wait to watch the next one!
Alex I love your videos and this one is no exception. I want you to review Kerr’s recent paper on Arxiv about rotating black holes and claiming the existence of something like a torus inside where the inner circle of the torus replaces the point singularity in a non rotating black hole (in other words it doesn’t exist since every hole is rotating) and inside this toroidal volume SPACETIME IS NAVIGABLE. Also let me remind of the Juan Maldecena’s reversible wormhole paper requiring entangled nonexotic mater on either end. Arranging that would be a sublight speed pain ITA but at least it isn’t exotic matter.
Time moves "at different speeds depending on what gravity fields you are moving through" is a really certainly concept. Thank you Alex.
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.
*fingers in my ear, yelling "la la la la la la la la" Interstellar is perfect.
interstellar is all the better for having imperfections, actually! It's a film where they say that love can transcend space and time and math, after all.. so if you love this film, why not take this story in the spirit it was told? love doesn't require perfection. It's all the more charming for its dips into science fiction.
@@otaku-chan4888 That's a pretty good interpretation
You describe me very well.😂😂😂 At least we saw in Corona times a depiction of our black hole in the milky way and it was actually Gargantua.
This episode was wonderful! More please!?
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)
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
I still don't know why they went down to that planet near a black hole.
IIRC they saw it had water and wanted to see if it had life or was habitable? Or something like that.
Because P L O T. Which ultimately why this movie is overrated. The plot has some pretty stupid things that are jarring and make it really difficult to watch.
I would think the tidal forces would be pretty extreme even on people. Like squishing you every time the planets rotation put you closer/further from the black hole. But maybe it’s not a dramatic amount. Gravity goes on forever but the intensity of gravity fades out pretty quick.
Well said.@@aserta
i cringed so hard on a few things so yeah its plot@@aserta
I'm not that smart but I'm really in to space topics... And the way he explains make it more easier to understand that's why I love astrum
❤ your page is one of the most legit informative medias sir 🙏🏻🙏🏻
The first and most glaring place they went wrong is the beyond ludicrous giant wave scene. Lower gravity or not there's no way a 2000' wave just rolls over 2' of water without breaking and at walking speed nonetheless.
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. To be honest I didn't really worry about the details as it was quite a spectacular scene. My issue before then was just the idea of living on a planet orbiting a black hole. That just seemed like the mother of all mistakes.
"No way" can't argue with that.
I was more surprised they didn't see waves from space when trying to labs the ship. I figured the ripples would be seen from afar.
@@simmorg290 Unfortunately for me I'm analytical and can't help myself. Watching movies w me can be annoying.🤷♂
But it's not a wave? It's a tidal surge. Unlike a wave, it's not in motion - that's the reason it exists: so what are you expecting to, "break"?.. They, haven't, "gone wrong" - you, have misunderstood? _Cooper_ calls it a wave - but what does he know, or care? His imperative is to communicate the danger and get the hell out of there - it's _we_ who have the benefit of time to consider the circumstances and come to more rational conclusions.
I am an artist and I am also in love with science and space, and this movie(interstellar) is my perfect blend of inspiration. This film, teaches me both filmmaking and the complexities of being near a black hole. I have watched it almost 9 times and my mind still blow away whenever I watch it. The technical artistry in crafting a sci-fi film, the precision in scientific accuracy, and the emotional depth make it an everlasting source of awe and creativity for me.
Astrum and cinema. Could not be more excited for this ep 🎉
Awesome video man!!
The tidal forces of the black hole on anything approaching it would have spaghettified it long before entering the event horizon. The accretion disc is proof of that - whatever once solid objects would have been spaghettified into plasma and then sent spinning into orbit around the black hole.
Not for supermassive black holes where the gradient can be quite low. Kip Thorne has written books about this and you could fall through the event horizon of a supermassive black hole (like at the centre of a galaxy) without noticing you'd passed the event horizon.
@@MikeMcCartney OK, thanks. I looked this up and you are quite correct. Strangely anti-intuitive, but the mathematics make it so. The Schwarzschild radius (the event horizon) is proportional to the mass of the black hole while tidal forces at the event horizon are proportional to the inverse of the square of the radius, so tidal forces become weaker as the mass and the diameter of the event horizon of the black hole gets bigger.
@@MikeMcCartney It's not possible. You cannot travel as fast as the speed of light which cannot escape the event horizon and you would die far, far before entering it.
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.
Awesome waiting for p2 etc…
Cooper: Don't let me leave, Murph Astrum: In this universe, we don't allow paradoxes
interstellar is hands down my favorite sci-fi movie of all time. really put me into a different space mentally and opened my mind.
Same
Lol
Wait until you try mushrooms
Late Happy New Year Astrum! Thanks for the first 2024 🥳🥳🥳
If you make this a series where you analyze the science behind famous space science fiction films, could you do 2001: A Space Odyssey? Scientific accuracy was a paramount priority for director Stanley Kubrick, but the film also implemented a lot of these more bizarre aspects seen in Interstellar.
Well, to be fair, the it was presumed a black hole by the films protagonists, but was a man-made structure by some hyper-advanced future humans. The mere fact that it was engineered is a useful catch-all that may suggest that while it may have had features of a black hole, it may also have wholly distinct features consequent of its design.
The black hole itself wasn't indicated to be a construction, don't be ridiculous? What was indicated to be constructed was the tesseract net, just behind the event horizon, to catch Copper.
@@lewis7515no, thor survived a nuclear star, so its likely he can survive that
My favorite thing about Interstellar was the very human dilemmas the characters encountered and how they dealt with them. At the deepest level, it recalls Campbell's "Hero With A Thousand Faces" in it's mythological undertones. Sci-Fi of the sort portrayed in this film is essentially an allegorical form of fiction, and I felt Nolan did a good job telling the story within the parameters of the convention he was working in.
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
My mom hated interstellar bc the dad left his kid
Your mom sounds basic af
Ha, women! 😂
Its for science Rise above
😂 If he hadn't left, everyone, including his kid, would have been doomed.
I would love to see an analysis of the planets in interstellar 😊
When I first watched Interstellar, I fell in love with the concept of the story and the use of time and space as it does.
A solution to the grandfather paradox was mentioned in tenet actually with the idea that there are infinitely many similar universes, cooper could’ve been interacting with not his own past, but an infinity of separate parallel universes, all with varying degrees of differences or no difference at all (copies)
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?
No. Because when you're going out of time dialation, the faster-moving time decreases the amount of fuel you need.
@@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 :)
@@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).
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.
There's a good stargate sg-1 episode where O'Neill is being pulled into a Stargate connected to a blackhole. He has to spend enormous amounts of energy (closer to the gravity well) to keep from being sucked in, but Teal'c is able to pull him up with way less force expended. Seems they did their research.
As a science fiction fan of 4 decades.....I like movies like Interstellar that blend fact with fantasy. Besides being a visual spectacle, this movie generated many discussions about space and time. It's been 10 years since it came out but it's still relevant to talk about. That's good science fiction. Thank you for this video Astrum. I look forward to additional videos on the planets and such!!!
I was waiting for the tidal wave exploration... Next time please!
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
There are countless other issues with interstellar; such as the issues with the mechanics of the "leave something behind" nonsense; you don't leave something behind, you have to PUSH something behind. The weird ice clouds on the ice planet. The internal tunnel depiction of the wormhole. Black holes found to be not being singularities throws a wrench in just about everything. Someone that wanted to pick apart the film could go on and on and on with inaccuracies in the film.
I don't mind movies taking some creative liberties if overall it tells a great story and is somewhat grounded in science. IMO, Interstellar is the greatest scifi mostly grounded in science since 2001: A Space Odyssey. As far as the one scene that I found most memorable, I have to say it is Miller's Planet with that giant tsunami. Such a great and interesting idea. I hope you make your follow up video soon!
Love your voice dude! Sounds like you have a huge grin on your face the whole time😁
I love Interstellar, because it's like Nolan took my childhood imagination, and all my daydreams from the age of 5, and put it on screen. I studied physics at university, and I was about to specialize in quantum mechanics, so I exactly know, in what ways this move got off the wheels of science. But I always viewed it as an artistic movie. IT is all symbolic. I also had this interpretation, that Cooper died at some point, and what we see is not happening to his physical body, rather its something beyond that.
Interstellar is just fantastic, even if there was a lot of creative liberty, watched it so many times and always loved it
...and since we now live in a high-tech dystopian technocratic neo-feudal society, you sir are sentenced to death via Molecular Spagettification within Gargantua for blasphemy. ;)
Hello astrum aka Alex
I'm completely satisfied with wibbley wobbly timey wimey explanations. I have been since my first introduction to The Doctor. Great video about an amazing subject.
Ohh how ive been waiting for a video like this 💯
I found Interstellar unsatisfactory. It came across to me as Nolan trying too hard to make his own 2001. But it simply wasn’t as good or as clever as that movie. And that sequence towards the end, in the tesseract just looked silly to me with the strings and endless libraries 🙄 it was emotion over intellect and pretty much ruined the movie for me. It just didn’t stick the landing IMO 🤷♂️
I enjoyed this better than 2001. It's fun to look back at old sifi movies of the past. Have a Happy New Year
@@dianaroach3093fair enough, each to their own. Happy new year to you too.
I recently watched Interstellar and I loved it. I like how it got a lot of things right.
how do you know ? nothing is proven . we know nothing about black holes , worm holes etc .. all speculation and guys with maths equations that create more question than answer
@@colinobrien3806 I wasn't talking about black holes and yes everything really said about black holes is just theory's I still like that in the movie they showed some of the theories. Of course some of it is science fiction, but it's still somewhat accurate
The bigger point of the movie wasn't about if it was scientifically accurate. The fact that it was 90% accurate & Infact the black hole they created looks almost like "real" black hole captured by Eht far later than interstellar just gives this movie the best science fiction movie award. Ps - Also that song mountains & it's math alone deserves a video on itself. How each tick in the song is 1 day passing on earth and all ticks add upto 23 years. 🙀 Pps - if you want to watch most scientifically accurate movie better watch Apolo 13. A video on that movie would be a great 2nd video in this series. Also do gravity, arrival. Would be great series to continue. & pls bring back the Astrum book. Pleaseeee.
movie was spectacular for the senses but lets not forget there is the movie The Fountain much much older than this one which was also an indulgence for the eyes ❤❤ love them both but for me the other ( The fountain ) one has a much deeper and complex story
Where they went wrong was suggesting that hormones and synapses can overcome space and time
People who game here from Sol’s rng😂
Great video - wanted to point out that, at least from what I understand, photons orbiting in the photon sphere will not stay forever. The orbits are very unstable and slight perturbations cause photons to fall in or be ejected out.
Thanks for this video! One of my favorite movies!
My biggest problem is they emphasize the science so much in some ways then completely ignore it for others. They went to the water planet first which wasted 20 years for the person they left on the ship, right? How much of Earth's time, which they're supposed to be finding answers for as quickly as possible, did they waste with this decision? And they talked a bunch about time dilation but then didn't factor this in to the decision to visit that planet first? If I remember correctly they were only concerned with fuel costs and maybe travel time. The inconsistent treatment of the science was jarring. These concepts are really important so we're going to use screen time to spell them out. Then we're going to completely ignore them when making important decisions...
Imagine in like 20 years this is actually what happens and this movie got everything correct
Unlikely, but not impossible.
@@aresaurelian Technically if the universe is infinite then somewhere this is actually how everything happened
damn
@Astrum. Well made vid. Astrum has always been (for me at least) very educational and down to science. I understand the urge to touch the fiction or follow the "what is wrong with this" trend. Astrum has always been the SCI and not the FI of the youtube. Can we please keep it the old way??
I have no preference one way or the other but I thought your comment was very well written :)
Interstellar is a top tier film, as a sci fi we can give it some latitude, the effects were absolutely incredible and the music too ..award winning
Thank you for this. I know I'm going to get a lot of hate for this but I never liked Interstellar and thought it was a stupid person's idea of a smart movie (just like most of Nolan's movies) notwithstanding Thorne's advice, and acknowledging this his advice was watered down and ignored in most cases. Its all relative. Relatively to a documentary, Interstellar is 1% accurate. But relatively to most other science fiction work before it, Interstellar is 80% accurate. It plays on people's emotions; love, and parenting, and legacy, and all that. And people fell for it.
I liked the movie when I saw it in the theater, but the more I thought about it, the dumber I thought it was, especially the ending when "love" is the answer to everything.
its strange to me that you got the whole concept of making a film this size, but somehow fail to realize that it is a film and not a documentary. therefore, what is there to fall for? you either like it or not, but please - don't look for answers in a hollywood blockbuster.
I personally like the movie, but I respect the opinion of somebody going against the grain and actually having their own opinion.
@@markuskenel I like Sci-fi. Favorite is Star Trek (the old shows). The science bits in ST is not even close to being accurate, but they don't claim to be. Even still, it influenced so much of our culture and even products because it was ahead of its time. Interstellar is the total opposite of that. The only think I liked about it were the visuals which are stunning. 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.
My favorite concept in the movie is that love is the only “force” that can transcend space and time. ❤
I felt that part was really contrived and silly, but I do understand why some people may like that part.
Love that movie and the consepts in it. On the onther hand we have so much to learn from the universe the whole consept is still big unknown to us more we learn more complex and wonderful our universe seems to be. We do not understand the way mass affects to the space time itself and make matter move the way it move, have have equtions go predect how it works but the why it is happening is still unknown!!. Quantum physics tell us that even the moment we are currently it might have some variations on it to forward in time and also backward in time, we just do not understand the consept of time,gravity and space time completely yet. It that sense this is facinating movie it flirts with the unknown so effortlessly, and have valid points like scientifically valid proven points like the gravitational time dilation, that makes this movie so wonderful. . . .
This movie was insanely thought provoking. I love this movie. Interstellar makes you think of how other planets could be and how crazy they can be too. Kind of reminds me of how a real life subnautica could be.
Spelling mistake in the title.
Where Astrum Went Wrong!
Gartantua is my favourite black hole
Thanks!
Thanks!
@@HighlandRockfoil Your mom is my favorite black hoel

I knew I would find atleast one comment about sols rng
@@sussycracksame😂
I was moved to tear after they returned to the ship from that water planet with the extreme waves, and Cooper realizes how many years he had missed of his daugther's life😭😭😭😭 And speaking of; those extreme waves. I hope you include them in your next video. I once asked my professor, and she said, compared to the distance to the Black Hole in the movie, the waves couldn't get that high. What do you say, Alex? 😅
Without basing this on any science, I'd assume that if the gravitational pull was strong enough to create waves that big on the planet that it would also be strong enough to eventually pull the planet itself into the black hole.
4:00 I like the way u had the wormholes moving away from each other, what if the space between the wormholes was such that u we’re further than light could travel to ur past self and therefore u couldn’t interact with ur past self and solving the paradox? Not sure if it’s said later in the episode or in one of the papers written about interstellar, just thought this stuff is fun to talk about
We can’t figure out a virus but we can travel across the galaxy… yeah…
That's called real life... or Sci-fi!
Nolan’s creative mind paired with Hans Zimmer’s musical genius makes for a thrilling and emotional cinematic experience. I think the beauty of it is that it combines what we know with what we don’t (yet) know. If anything, Interstellar serves as one gargantuant reminder that we don’t know half as much as we like to think we do 😏
Hans Zimmer is overrated
