--------------------------------------------
Script:
We touch upon the fundamentals of this topic from our previous video, about Einstein’s relativity. You can check out the video here, but just to give you a brief summary, we can say the following.
Under the influence of a strong gravitational field, time slows down. So if you’re just hanging out near a massive object, you will experience the effect of time going slower.
But gravity isn’t the only thing that can warp time. According to another one of Einstein's theories, special relativity, time slows down for an object when it moves. Combining these two concepts together, we could consider this scenario.
Suppose that we walk up a flight of stairs. Our body is slowly moved away from earth, meaning that we will experience time going faster. But at the same time, since we are not stationary while going up, we should experience time going slower. So being farther from the pull of Earth's gravity causes our clock to tick faster, but moving “counteracts” this effect. Of course, this is all oversimplified.
Let’s consider two comparable cases. We have person A, floating nearby a massive object with a lot of gravity. And person B, just casually floating in an empty void of space.
Person A shines a green laser beam toward person B. Because light is a form of vibration, the laser beam has a color that corresponds to 600 trillion vib/s. Now light is also a form of energy, and as that beam of light comes out of that gravity of the massive object, it loses a lot of energy. This loss means that there’s a decrease in frequency.
So, by the time that beam of light reaches person B, its frequency will have decreased by some factor. That means that instead of the green light, at six hundred trillion vibrations a sec, person B gets only.. let’s say 10 billion vib/s. Which is a microwave radio beam. This phenomenon is called the gravitational redshift.
Individual wiggles don't just go anywhere and disappear. Since person A creates 600 trillion wiggles every sec, while person B only gets 10 billion every second, the only way this can happen is if one second on one astronaut’s clock is not the same as one second on the other astronaut.
In other words, it only takes one sec for person A to create those 600 trillion wiggles, but it will take 60,000 seconds, or nearly a day, for person B to receive them. So this is what happens. Our clocks run at wildly different rates. And by "clocks" I don't just mean mechanical or electronic devices, but also biological clocks, like your heart, your lungs, your brain, etc.
Person A takes a breath, takes another breath, and measures a few seconds between the two. For him, everything feels normal. Clocks tick the way they are supposed to. On the other hand person B, watching person A through a telescope, sees everything in slow motion, with several days passing between the two breaths.
So now revisiting this scene again from #Interstellar, you should get a better understanding as to why Cooper says he will be the same age as his daughter by the time he comes back from the mission.
According to Einstein’s special relativity, the greater the acceleration of an object, the slower it will move through time. On Earth, where time is slowed by only a few microseconds per day, gravity’s pull is modest. And at the surface of a black hole, time is slowed to a halt, where the gravity is so humongous that nothing can escape.
In the movie, Miller’s planet is depicted to be present in the warped space, very close to a black hole Gargantua. Gravity’s pull on Miller’s planet is enormous. So if we apply Einstein’s relativity here, we would know that Miller’s planet would experience time at a very slow rate. But here on Earth, gravity is at a modest rate. And the gravitational force of the sun is also a billion times weaker than Gargantua. So people on Earth “experience time” faster than that of the three astronauts on Miller’s planet.

[@MichaelOrtega]

@@futuretrunks3158 Not suspicious at all because the image of the black hole had been in the Works years before the movie was made. It wasn’t like they just all of a sudden decided to release the picture that they took yesterday….They were working on the picture of the black hole for a really long time. Even before the movie was released. And just so you know, the mathematical equation for the black hole came from Einstein. It’s just been revised many times to see if we could get more accurate descriptions of it over the decades. It’s just a computing power has improved tremendously over the last few decades to the point that now we can use math to reconstruct an image. Because science uses a lot of computers as well having the same advancement in computing power means that we now are able to do more in the real world not just Hollywood. There’s a lot of things that improve at the same time because of computing power increasing

I see very few comments stating this. The time dilation is not because of the planet's gravity, but because of its proximity to the black hole. I am assuming the planet's sun is in orbit around the black hole at an extremely high speed so as not to fall into it. The high gravity of the black hole along with the high speed creates the time dilation.

[@WorksopGimp]

If it did the centrifugal force whould cause it to spin apart, this is a paradox for Quazars that spin and massive speeds I was reading. Time is a concept its not physical once you get that you realise its all made up

Totally correct, time dilation is coming from the black hole, not the planet itself. Also in the movie, the "star" is dark in the center. It's actually the black hole. It's halo is so bright that it acts like a star in the movie

[@panner11]

Yeah a shame the video missed this. An easy way to imagine it, is that the astronauts on the ISS experience weightlessness, however they experience the same gravitational time dilation regardless. This is because they are in orbit and the same gravitational force is acting on them. The planet in interstellar is like the ISS in this case. The astronauts and the planet both experience the massive gravitational force of the black hole. However, since both are accelerating in the same orbit, the astronaut only 'feel' the gravity of the planet. That being said, that orbit would be insane, so for the spacecraft to follow the orbit to land would be a intense process in itself. It kinda sucks that the video missed the ultimate conclusion of the discussion of why they experience that dilation.

Time dilation is one of the craziest things our species has ever discovered. I remember in the original Cosmos series, Carl Sagan gave the example of twins experiencing time dilation in a thought experiment. One twin would be kid and the other would be a 50 year old man depending on the gravitational force enacted on each of them. It’s funny in certain areas of physics your mind just breaks down trying to comprehend some of these seemingly impossible realities. I suppose if you know the math intuitively, you have some sort of a framework to grasp your mind around it.

[@xXxXcrosbykidXxXx]

@@msavage960 I partially agree with you but I think you're putting too much weight in just the intellectual side of the movie. The screen time actually exploring new worlds is pretty good, but a lot of world building is forced through rushed dialogue rather than being shown or made understood through proper storytelling. It plays like a movie that has about 30 minutes or an hour of scenes cut from the beginning and end, to appease an audience with a short attention span. I think Phil's criticism's are each entirely fair, and actually a pretty astute summation of the hype surrounding this movie. That said, it's entertainment, it doesn't have to be educational, and it doesn't have to be meaningful. What it does have to do is capture people's imaginations, which it does, and as a beneficial side effect, it seems to inspire at least some viewers to learn and understand some of the complex physics theories that gave birth to this fictional tale. Masterpiece is a strong word though, if objectively looking at some of the screen writing, storytelling, and special effects (particularly while in the ship going through the black hole. All goes pitch black at first, this seems logical, but then slow water droplets and sparks descend on a prop ship that's pretty obviously stationary on a sounstage.. and that's meant to represent the most mindboggling experience of human history?), it's kind of underwhelming really. I really enjoyed the movie, but there were also moments that made no sense and completely took me out of the experience, and back in to a critical mindset. The whole thing should've at the very least been postponed when the girl who discovers the interdimensional gravitational message decodes it before the mission even takes place. That earth shattering revelation in not even given one second of consideration in the plot.. and that's not the only instance of rushing over what should be massively important plot building scenarios. I wouldn't go so far as to call somebody a douchebag, for simply trying to convey these factual criticisms in a straight forward sense.

The time dilation on Miller's planet isn't from the gravity of the planet. The planet is orbiting the black hole, at which it would gain such an extreme velocity that would make that kind of time dilation possible.

[@MarkDavis77]

@@jacksonraidal9917 Yeah, was looking for this comment actually. Channel is new so he'll prob get it worked out. From a technical standpoint, the reason the time dilation is so extreme on Miller's planet is that Gargantua is not only a black hole, but it is _also_ spinning. The spinning of the black hole causes it to drag spacetime as it rotates which further increases the dilation. That fucker Phil Plait got that part wrong and was...gently corrected by Kip Thorne.

No.. this planet is in gravitational field of black hole. You would experience dilatation not only on this planet but in gravitational field depending on how close you are to singularity. So still makes no sense to me.

A simple definition of time dialation: the faster you are moving through space, in other words, the closer you are to the speed of light, the more time slows down for you. If you are moving exactly at the speed of light, time will completely stop. And if you are moving faster than the speed of light, time starts to go backwards. Let me give a simple example: imagine you are racing a guy named "Time" who is always driving at the constant speed of 100KM/H, neither faster nor slower. You are behind him at the speed of 60KM/H. If you lower your speed it will seem like "Time" is going faster even he's at the constant speed of 100KM/H. Now if you increase your speed it will seem like "Time" is slowing down and when you also reach 100KM/H, you and "Time" will be in the exact level, both of you being still on each others perspective. Now if you increase your speed even further to 120KM/H, "Time" will go behind you.

It is very volatile so it dies extremely quickly when it reaches our atmosphere but it also moves at speeds close to the speed of light.
