Interstellar EXTREME TIME DILATION Explained - Reaction!

2:47 What's happening here is, according to special theory of relativity, the faster you move through space, the slower your time ticks and according to general theory of relativity, greater the gravitational force, slower the time ticks. So the person is climbing stairs, that means they're going away from gravitational force, so their clock must tick faster but as they're moving, their clock ticks slower so it counter acts

Regarding 8:12, we know that redshifting only happens if two people are sufficiently far away and are accelerating *away* from each other. In his example, both of them are actually stationary and so the only thing thats causing the red shift is the big ass body/star near person B. This is because redshifting happens not because of "moving away" per se, rather that the fabric of space-time actually stretches out causing light to reach you slower because it takes more time to travel to you.

[@Excanda]

actually I think they say it's redshifted because the gravitational pull of the stellar object pulls the light beam towards it, it will look as if it's moving away as it is being pulled back the further it goes until it escapes the gravity well of the stellar object and thus losing a lot of it's energy escaping.

[@mogammedflanders4240]

8:00 So I think it legitimately slows down the particles spinning around the atoms. That's straight up time freezing, like the laws of the universe have to balance and time gets warped around in the collateral. So nuts I love it.

Nice 🔥🔥

[@shreyashdeshmukh3939]

The thing is that, the person near the extreme gravitational pull will be older than the person near the less gravitational pull. When cooper went near the gargantua, he actually lost 52 earth years of time. Means he became 52 years older to the people on earth at that time but didnt actually aged at all. Conclusion is, a person near extreme gravitational pull will become older than a person near less gravitational pull but wont appear to be aged at all.

[@INSTAFLIXMEDIA]

Jaby is really dense. This video feels like two class 5 students trying to understand research papers.

[@graceonfilmsnstuff]

the oversimplified example near the beginning was pretty easy if we ignore the devil in the details as he said. conceptually, moving away from earth's gravitational center relaxes the fabric of time (as it does to space too) so time gets faster (albeit very very miniscule). conversely, it means time slows down as you go towards a gravitational mass center, like the earth's in this example, or gargantuan in Interstellar. at the same time, the figure is walking forwards as it gains altitude right? so the forward motion as with any motion also affects time, as in it makes it slower. closer to speed of light if one goes time slows down almost to a standstill. so the forward motion of moving through stairs slows time and upward motion of moving up stairs fastens time which balances each other out.

[@TheAstroG]

ohh..wow

[@mbs9908]

Yeah like that was so easy to understand considering how he explained it

[@graceonfilmsnstuff]

[@polterkat]

"Twin Paradox" = There are two twins. One is an astronaut who gets in a spaceship traveling away from Earth near the speed of light for one year before returning at the same speed. When the astronaut twin arrives back at home where they started they will be two years older than when they left but their twin will be several/many years older That is the "Twin Paradox" as I've always heard it. I don't know what this "one twin grows up on a beach while the other grows up on a mountain"-version is but I guess it also works. I can't say it's LESS confusing cuz the twin in a spaceship is also not terribly simple to grasp... but it is interesting you've got some totally different idea of what the "Twin Paradox" is than I do (/my physicist mother and her college textbooks I used to read as a child do)

[@dragos-lucian]

Look at it this way: The fabric of spacetime at ground zero has time running at one speed. An object, or planet in this case, pushes on that spacetime fabric and puts some weight on it depending on its mass. The bigger the mass, the further down the fabric gets warped, the bigger the time difference. If you put one twin in a spaceship in space with no stars, etc, around him for thousands of light-years that way leaving that fabric of spacetime unaltered, the other twin back on Earth would age slower. The "oversimplified" staircase example is too vague to be understood the way it's intended to.

[@seematyagi1750]

Collecting All solutions of relative theory and combing in it a movie

[@prashantmishra2205]

😂 It's fine. This stuff uses a lot of concepts of physics. To explain it as simply as possible. Point 1: High gravity > slow time. Point 2: High speed > slow time. Point 3: Gravity is related to distance. You go away from earth when you climb, so you feel less gravity. So you reverse the concept. Less gravity > faster time. Person A goes close to a black hole > very high gravity > very slow time. Point 4: Slow time simply means that it passes slowly for the one having it. He spends 1 hr. And the world is years older. Time dilated for him. Due to gravity. Think of the same idea from both perspectives.

[@siddharthapattisapu4706]

Regarding the Wiggle thing: It's normal for you, meaning you'll have 24 hrs in your day while you "observe" that the other astronaut near the black hole has much more. So say there's a time dialation of a factor of two, you'll spend 24 hrs while the other guy would spend only 12 hrs in the same duration

[@sudhirbabu548]

The other guy would seem like they spent only 12hrs. In reality the other guy in his place would have spent 24hrs as well. It's all about relativity. So relative observations. It's only about how things look to you..

[@pranavsharma8807]

idk why jaby is thinking that the wiggles will slow down even if both the astronauts are in the low gravitational zones...the wiggles slow down because the light is losing energy to break the high gravitational barrier..and energy is dissipated..to reach the astr. B...if both are in low Gr. zones...or similar Gr. zones....there will be miniscule loss of energy..and the wiggles will remain high...no need to break the high gravitation barrier.....He is missing the point.....

[@abyjames6151]

8:54 the action n diolouge makes so much sence .

[@GIRGHGH]

What they were saying was the gravity AND motion affect time. Leaving gravity speeds up time, but moving faster slows down time. Speeding up slows your clock, just as getting closer to a gravitational center does. Because gravity is an acceleration, there's no distinguishing between the two.

[@DJDavis844]

Fast way to understand: You fill your tub with 3 inches of water. Now you have 2 small pieces of wood. Wood absorbs water and becomes rotten. You place the 2 pieces of wood in the tub: one by the drain. and the other furthest from the drain. The one closest to the drain absorbs LESS water (or stays more fresh/looks more young) before going down the hole. The one furthest away from the drain absorbs MORE water (or becomes rotten faster/getting older) before going down the hole because it is slowly moving through the entire tub of water absorbing as much as it can. If you've ever noticed things move faster the closer it gets to the drain, that means 1 second happens faster as the object moves closer to the drain versus being further away. Just replace the 2 pieces of wood with humans and then the tub of water with outer space and the drain as a blackhole

[@nunyabusiness9013]

The simplest way to understand it is that space and time are the same "fabric." Since intense gravitational fields warp space, they also warp time.

[@warren286]

Time dilation is actually all about the warping of space-time. Going near light speed actually increases your own gravity bc you gain more mass in the form of kinetic energy. E=mc^2

[@datdudeinred]

9:36 what you were talking about jaby is redshift due to distance it has to be billions of light years away to have that effect what the guy in the video was explaining was gravitational redshift which can be caused irrespective of distance bet astronaut a & b.

[@nefariousarcher2484]

Sometimes it’s easy to get the concept of time dilation twisted, especially when the terms “time slows down” or “time speeds up” get thrown around. It’s important to realize that this is an exterior perspective, not an interior one. You, the person experiencing the change to time, do not perceive a difference. Everything proceeds normally from your perspective. It is other people’s perspectives of you that appear either accelerated or decelerated. Also remember that time is not this static constantly flowing thing that we humans have assigned to it to make it easy to count and denote. Time itself, much like space, is non-static, always warping and malleable. It moves at different rates in different places depending on the local environment. Hopefully that helps clear up any questions that may remain.

I think the host couldve done a better job of explaining things. the time difference you observe is relative to a single subject. for example, the time near black hole relative to time on earth. i think that's what was tripping you up. 'Time slows down, compared to what?', relative to the observer, hense "relativity". checkout Star Talk channel ft. Neil Tyson, has a waaay more intuitive way of explaining it

[@soumyadipbanerjee6744]

In 9:13 to 9:36 Jaby says that he think gravitational redshift happens irrespective of the position of the two observers but that's clearly not the case. It's called Gravitational redshift for a reason; it only happens when the two observers are in regions where the gravitational field are different from each other, so the fact that Jaby thinks it happens all the time is wrong. You got to have a massive object for that to happen.

[@kevinjp12249]

Jaby is finding really hard for a simple explanation in the video

[@HalkerVeil]

17:40 They leave out that the planet is near the black hole. And that it's orbiting the black hole which makes time go even faster outside of it.

[@PabitraPadhy]

The closer you are to a massive gravitational object, time moves slower for you. That's where the "Relativity" comes into picture, because time is relative.

No, Jonathan Nolan wrote the film as a short film script and Christopher Nolan wrote it as a screenplay and brought Kip Thorne on board as a consultant, and Kip Throne came in and ended up changing a lot of the story since the science wasn't sound.

[@talkingmeme1101]

Gravity and speed are inversely proportional to time. Steps climbing thing: climbing up means less and less gravitational force on u. So time faster for u. But ur moving with some speed, so time slows down for u. Hence they both cancle out.

[@EggTronics31]

People got confused by his oversimplification. You have to understand the age of person or ( passage of time ) is getting effected by two things. One is gravity ( whether you are moving or not is irrelevant). Second is motion/speed irrespective of gravity. So gravity and* speed both effects time, they have opposite effect in the first example, so cancel out each other.

[@vikashtiwari2928]

This may sound really odd and some of you may call me Old Let me tell you a story from Hindu Scriptures.

Lord Brahma said but now it cannot be done because all the guys of her age must have died by now on earth because the time runs difference on earth and on Ram Lok another look beyond Earth. You may google her name for better understanding

[@rushabhsagara8766]

Honestly, I am surprised that no one here is noticing the error in the video at 12:33 when the fact is that Einstein's special relativity has nothing to do with acceleration per say! It just talks about the effect of higher velocity on the observing person and his frame of reference. In fact, it was in between 1905 (when Einstein published 'special theory of relativity') and 1915 (when Einstein published 'General theory of relativity'), that Einstein theorized upon the effects of acceleration on time, and along the way, he also theorized how even gravity is nothing but acceleration in a way (the elevator thought experiment). And that's how he was able to connect the dots on how "gravity is not a force in the traditional sense but just an effect of the warping of the fabric of the space-time continuum due to objects having mass". To be honest, the video in review just complicates the matter a lot for a lay person in understanding the theories of relativity, which in my humble opinion, is arguably, the greatest creation of human brain!

[@karateman302]

I will attempt to explain the whole 'velocity making time go slower bit.' If you stand on the ground and throw a ball with a certain amount of force, it will move a certain speed. If you then stand on top of a train that is moving at a constant speed and throw the ball with the same force (ignore things like air resistance for the examples), it will travel at the speed you measured when standing still plus the speed of the train. Now we repeat the same thought experiment but use a beam of light instead of a ball. Imagine you're aiming a laser at a target off in the distance and shine it while standing still and on the moving train from the same distance. Will the laser reach the target faster if you're on the train? No it will not because the speed of light is the 'speed limit of the universe' and they'll reach the target in the same amount of time. This appears to be contradictory because if you're on the train and turn on the laser, the light should move away from you at the speed of light but if you're moving along with it and it reaches the target in the same amount of time as if you were still then the light would move slower than the speed of light from your perspective. This is where time dilation comes into affect. Special relativity says that if you are moving, time passes slightly slower for you. In the case where you're on the train, this distortion causes you to perceive the light moving at the speed it should because less time has passed for you in that frame of reference and so you don't perceive the discrepancy caused by you moving. We don't notice this in normal life because we move much too slowly in comparison to the speed of light. This was just my attempt to explain it. I'm sure someone else will be able to put it in a more succinct way but this is just in case anyone was still wondering.

[@seematyagi1750]

Interstellar is a masterpiece

[@ILJtheFirst]

The person near gravity and the person farther away. Just think of one moving normally and the other moving slower/ faster. You confuse yourself in thinking one is faster and one is slower.

[@samarthbhandavale9815]

Simplest way to understand this is more close you are to a object, time goes slow for u. It also depends on how strong the gravitational pull or the field is of that object

[@coldflamebluedragon196]

[@balkrushnakadam7082]

Working of four fundamentals forces ( weak force, strong force, electromagnetic force and gravity) animates matter and the rate at which this forces act is time, and the rate of acting of these forces is affected by stretching of spacetime fabric due to gravity.

[@sreenath2539]

Anthony alba on the thumbnail 🤣

[@prasadt772]

For earth, the gravitational component of time dilation are miniscule as compared to component due to motion. Atomic clock on a fast moving plane will run slowly but at the same time it will run a little bit faster because of being under influence of weaker gravity. So the net result will be that the clocks on the fast moving plane will run slower as stated earlier.

[@satyakamshashwat]

As you discussed in middle of the video, there is dilation because of speed and gravity When you come close to speed of light, the way time moves is relatively slower than before... so when you are very fast, everything else (light / clocks / quarks etc.) seems slow for you - that is time dilation because of speed When you are close to a super massive object, (having great gravity pull) it pulls in the light towards it, in other words, it drains the energy from the light. Thus, again the light seems to be slower and hence the dilation. In this Video, this thing is explained with frequency of beam of light, as the energy is directly proportional to frequency (E = hv ) frequency goes down for a light when it passes through the super massive object. This is because gravity is slowing down the light

[@A-myth]

The main basic question is which ll solve all confusions - What is time? How can u quantify it? Is it the vibrations of your atoms? Is it some property of the environment? Since time is relative..is time just YOU, your property.

[@mukeshsaxena5603]

Satellites on earth orbit moves back in time but very slowly.

This stuff always messes with my mind, but the part of this movie that really got me was another video explaining the gravitational forces that would have been on Miller’s Planet. Basically, that video was saying that they would have been crushed before they even touched ground.

[@zjjla6283]

Isn't Miller's gravity 130% earth's? Meaning it's 30% more powerful than earth's.

[@loganshaw4527]

But the gravity you would be feeling would not be form the planet it would be form the black hole. Hmm 🤔 maybe you would not feel the gravity at all. If the time you feel is extremely small so would the gravity. Because the extreme gravity is stacked over time. Gravity is a time sink light can not escape a black because it is no longer going fast enough to escape it is to slow. What can make light slow? time. The more time it would have to take to get a certain distance the slower it is.

[@jagadishk4513]

Two aspects with regards time were : The closer you're to a massive object the slower the time ticks there. The closer the objects speed to the speed of light, the object moves through space predominantly and less in time so time ticks slower in this instance. Conversely the farther you're away from a massive object, faster the time ticks in that case and, slower the movement of an object through space then it moves predominantly through time. You can imagine space time as x and y axis, it helps. Every motion is relative becuz of relativity. Fun fact- photon doesn't age cuz it moves completely through space and not time.

[@TrevorJoestar]

At 8:00 jaby that's literally why it's called relativity

[@thorny8013]

11:35 Okay....so...it HAS to do with speed more that it has to do with gravity. Gravity causes time dilation is what we hear..but people do not realize that the reason Gravity causes this effect because being under gravity is equivalent to being under constant acceleration.

[@kabyajitchoudhury4179]

Light also have energy so when it goes to the next person because of it's large distance it's losses it's energy so that the person A light wave is more faster than the person B and also the person A light wave is more faster than the person B because of the huge amount of gravitation so the time shows it's differences and that is time dilation

[@warren286]

Wrong, the clock in orbit was aging faster, the one on earth aged slower, bc the difference in gravity is much more than in orbit; also, the clock in orbit slowed down a miniscule amount due to it's speed, but it being so far from earth's surface dwarfs it's gain in velocity.

Going up (altitude) makes time go faster, this is why the mountain twin aged more. Nonetheless, moving at all makes the time go slower (Einstein's theory) So, basically, going up the stairs cancels time change. Also, time is f***ing insane!

[@amankishore3512]

The point is time in not absolute it is relative. So is reality

[@mukeshsaxena5603]

No light escapes from black hole, so the black hole is actually slowing down time so much that the light can not escape it. Therefore a planet close to a black hole is running very slow relative to the clock of universe/Earth.

I wish time dilation was used more in sci-fi storytelling; it can lead to some really interesting plots.

[@RitwickChatterjee14]

You need to understand the concept of relativity completely.. especially about the Frame of Reference. And also as said in the video - Time or clock is not about the mechanical clock which is used as indication of time measurement - it's more about the Biological clock of the physical elements; the ageing of the physical bodies.. So when both the frame of references are exclusive - then of course they both will be normal, every thing looks and feels normal in their respective frames (Astronaut A & B - both will individually have their clocks at normal speed). The insane concept comes into the picture when you are trying to look/feel time cross frame of reference. When A looks at B - it feels everything happening at B's side is very slow respective to its own time reference. While when B looks at A - it feels A's side, everything is running in fast-forward respective to their own time reference. That's because both are in different gravitational field - or say in different space-time. The heavy gravitational field near B stretches the space-time and make the light travel through it slow before reaching to the A's frame. Therefore, A is receiving the same amount of light energy but over a greater period of time than what originally B sent across. (Light warps around the field as well and the fact both A and B needs to be really really far away in the space to observe this phenomenon and it will then obviously gets delayed - bcz light can travel at max on a certain speed (c)- but that's different topic). Putting into Interstellar reference now - When Cooper is on Miller's planet - the time (biological clock) is running slower because of the increased gravitational field as compared to his daughter's biological clock back on earth. So what it means, because of such immense gravitational pull, everything till the tiniest of atoms are slowed down in that space-time field - thus Cooper's body is ageing slower than of his daughter on the Earth at a rate of 1sec on Miller = 21hr on the Earth. But in their own respective reference frames - everything is normal. The movie is showing us both of these frames from a *non-affected/unbiased from all the physics concepts* frame of reference.. to help us compare between the first 2. And personally - I think such presentation of time dilation concept usually throw off the non-scientific people - either it makes them confused or it intrigues them to dive deeper. And as the video and you said - The Interstellar movie in itself is just a Science Fiction depicting a very fundamental yet the complicated astro-physical concept known to human kind till date. And when it comes to understanding such concepts through movies and videos - the best way is to detach yourselves from the characters in the 2 frames and look at it from the frame which the movie is showing. P.S: I love how Ambre tries to put it in words to what's going in her mind while trying to explain a concept shown on the video in as short and simple possible way - but she gets caught up between her own explanation the concept originally and the explanation presented by the video creator.😅 It happens to all!

no wonder there's something I heard from someone on tv that says you age slowly if you always use stairs.

Jaby, Genius: Season 1 - Is a drama series based on Einstiens Life. It would be a great watch for you even if you don't want to react to it. I highly recommend it.

Man why people always use big words and complicate things, here is simple thing : You are moving/in motion = Time moves faster for you and stationary/standing still = Time moves slower for you Same for gravity - The more/stronger gravity you are near = slower time, less gravity (moving away from earth) = faster time

The amount of Detail Christopher Nolan puts in his films is sometimes beyond understanding unless u watch some explanation. Like that ticking score thing had some purpose I didn't know that before. To tell such complex concepts in movies your story should be also equally good as that , means having a good blend of reality and fiction 🤓
