Time itself cannot be manipulated only in the ways we record time. Images move at the speed of light,so therefore you can move faster than images and get far enough ahead to see yourself start the journey. Important too remember is your mass occupies the same space no matter the speed.

The fact that the movie makers came up with the black hole’s design using an mathematical equation and a visual software engine is amazing, and on top of that, some years later the first photograph of a black hole was taken, and it looks hella similar to the movie one. Just amazing!!!

[@futuretrunks3158]

Just suspicious if you ask me

[@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

Lemme explain it to you. The picture of a black hole they reconstruct, they could not do it earlier because (as that woman showed, said and collect it, and was major part of the project) of lack Of storage and computer/technology power. But finally they managed to collect, reconstruct and render image, and still it took a lot of time for computer to finish it. Technology is amazing

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.

@@philsurtees Ah, a movie critic.

[@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.

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.

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.

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.

@USERZ123 sure, practically speaking, it’s not feasible to actually experience this feature of the universe. The movie contrives a situation where apes would adventure through the vastness of space to a place experiencing extreme gravity and then later return to their point of origin (the Solar System in this case, I’m aware Matt Mac isn’t show returning to earth itself). The point is that: if we could do this thing - survive it - and that planet had the requisite level of gravity to produce the stated time shift, this is precisely what would happen. Relativity isn’t just pure mathematics like some of the comments here suggest. It has been proven experimentally every single day for a century now. When that guy talks about redshift - that’s real time dilation we can see with telescopes. We don’t need to actually experience it to see it happening - astronomers and astrophysicists see it happening every day in the form of red shift. Relativity is among the most bullet proof areas of our scientific knowledge. If relativity suddenly stopped working no one’s life on this planet would be remote similar to what it is today. It was only with relativity that we were able to flesh out our knowledge of elementary particles, develop the standard model and quantum electrodynamics. It’s not just the GPS example that gets posted in the discussion - it’s all integrated circuits. Every single IC in the world is experimental proof of relativity and quantum physics.

They were already in warped space before landing, but to ground the audience the dialogue switches quickly from 'close to Gargantua' (the black hole) to 'on the planet.' So I think the questions about gravity and time time dilation needs more discussion. I am no physicist, so I don't have answers. Just noticed a discrepancy in how the movie is discussed here. 🙂

Totally agree. I honestly think this video got some things wrong. It's mentioning the concept of "acceleration" being a factor of time dilation, though I'm pretty sure it's just relative speed - not acceleration - otherwise we wouldn't have the time dilation issue with our satellites and the ISS ( they don't constantly accelerate). So not only does this video gets it wrong, it also just forgets about that concept which can easily explain why a planet so close to a black hole may experience high orbital speed relative to other bodies in space.

8:40 You are missing the point (source) of the gravitational time dilation effect here. It is not the gravity of Miller's planet that creates the time dilation that the crew undergoes, but rather it from the supermassive black hole (BH) that the planet is orbiting. The BH has an effect on the spacetime (curvature) around its horizon that is slowing down time as you get closer to the horizon (where time would come to stop at the actual BH horizon). You can calculate the mass and radius from the BH horizon from Einstein's GR field equations, using... (time near BH)/(time on Earth) = sqrt( 1 - 2GM/(rc^2) ) note: this is the familiar gravitational time dilation equation where M is mass of BH and for the movie, we can approximate r as the distance from BH to Miller's planet. Also c is speed of light and G is gravitational constant. Then, 3600s/(2.21x10^8s) = sqrt( 1 - 2GM/(rc^2) ) ... using the 7 yr on Earth to 1 hr on Miller's planet (near massive BH) M/r = (c^2/2G)*(1 - ( 3600/(2.21x10^8) )^2 )*(SolarMass/(2x10^30 kg)*(10^6m/RadiusEarth) ... using conversions to solar mass and earth radius. M/r = 337 * (SolarMass/RadiusEarth) ... after doing the calculation using the usual constants. One type of intermediate BH would have a typical ratio of M/R = 1000 * (SolarMass/RadiusEarth), where M is BH mass and R is Schwarzschild radius (ie, event horizon of BH). Therefore, for the example in the film, dividing this typical M/R ratio by M/r (we calc above) gives... r/R = 1000/337 r = 3*R ... this would show the distance between Miller's planet and BH at three times the size of BH (event horizon) in order that the gravitational time dilation effects from film to hold true.

We were only talking about this the other day when I was trying to explain spacetime (in the context of the film) to my wife. It wasn’t easy and she’d had enough by the end. Next week I will tackle the offside rule in football/soccer. (No pun intended).

Lmao

[@Powermad-bu4em]

Start with the hockey offside and then go from there. Maybe she won't stab you before you're done.

[@Immaculate_he4rt]

I wonder if it was your explaining while she was trying to watch the movie that she’d had enough of.

[@najeebullahkhan7988]

When you're near a strong gravitational pull, it slows down your movements but it also slows down your thinking and perception. So for you everything looks fine and normal. But not for the person who is watching you from a distance with less Gravitational pull.

Time dilation happens to us all time 😊. As the saying goes, “Time flys when you are having fun!” When we sleep, being asleep for 8 hours does not feel like being awake for 8 hours.

Even thought I’m not necessarily interested in this topic, this video is amazing. One of the best quality videos I’ve seen.

[@isaacconder9901]

I see you with the kemba profile pic

I don't know why I got this video in my feed but I love it! It's just amazing how the universe works that I got chills. Truly magnificent. For as long as I was a kid I wanted when I pass away for my body to be sent into space in a capsule( I know it's a bit weird) so I can travel through space for eternity.

[@gioblankk]

Interstellar isn’ttt how the universe works, sorry bud. It’s actually total bs side from the fact they got the aging part half right. It’s okay though, really, the reality of our universe will ALWAYS beat science fiction. Any. Day. Stay safe!

[@deebznutz100]

I was under the impression that the effects of time dilation were coming from the proximity of Miller's Planet to Gargantua not Miller's Planet itself. Also I've wondered if speed and extreme gravity are connected somehow. Like if you are close to a black hole but not falling in, space itself is moving past you at a very high rate, causing time dilation. Just like of you were traveling near the speed of light but space is moving not you... In a sense. But if you were to fall in, moving at the same rate as space falling in, time dilation doesn't occur. Just my idea of how time dilation might work.

[@ChaotikmindSrc]

You can't "fall" or move in empty space, you need another reference point to start to be able to say that. But yeah you're right the video completely messed up the gravity of the black hole wit the gravity of he planet.

[@o_sch]

Here: kzbin.info/www/bejne/raPamHygd7qMjMU As you can see in that video spacetime is being continually pulled down showing how you are moving. And yes speed and gravity are connected because of this. Time is also connected via the concept of spacetime continuum(continuum means you cant go backwards in time though)

Spaghettification XD

[@robya.2223]

Interesting... as if gravity equals space suction.

[@sciencesociety2919]

Gravity is just acceleration, and when there is acceleration, there is velocity. Now, the equation of relativistic time dilation is different than the equation of gravitational time dilation. Also, gravitational time dilation is more powerful, efficient, and long-ranging than relativistic time dilation. But you would need to get near a black hole to feel any of its effects just like you need to get close to the speed of light to truly feel the effects of special relativity.

[@waino8022]

Best video I’ve seen on time dilation!

[@random4573]

0:40. They forgot to consider the time dialation occured during there journey to the planet. Time dialation is due the massive object present near the planet which is BlackHole. So while getting closer to the planet there time dialation has already started.

[@karthikshari3517]

The more the mass an object has the more it will bend

[@renoels]

I was looking for this comment

[@michaeljorgensen790]

Exactly. This video seems to start out on the right track...and then switches to thinking that landing on the planet is when the extreme time dilation effect started occurring. The planet had very very little to due with the time difference. It was the proximity to the black hole. How close to the event horizon the planet was orbiting the black hole.

[@hulyan8944]

Not just the gravity, but also the speed at which Miller's planet revolves around the black hole dilates time

[@krikeydial3430]

Yes thank you! Mercury experiences significant dilation from its proximity to the sun. If you scale that up to a black hole you would experience extreme dilation. This guy needs to junk this video.

[@antares-the-one]

but if you calculate real values you'll find out that there are no materials in the universe which could withstand the title force of the gravity needed to achieve 64 000 times of time dilation and that is in a combination with the speed at which the planet should move to compensate for "stable" orbit. Film is incorrect by orders of magnitude

[@antares-the-one]

@@krikeydial3430 you need to junk your brain

[@preoccupied4800]

@@antares-the-one That's incorrect. Look up Schrwartzschild radius for a 3 solar mass black hole, the gravitational field would only be 13.5km R=2GM/c2

[@antares-the-one]

@@preoccupied4800 "that's incorrect" - i would be happy if you could specify what exactly is incorrect? And do you mean event horizon would be 13.5 km radius for 3 Mo black hole? Sounds reasonable but i cannot wrap my head around the reasons why would you drop that in here? Calculate the distance to the event horizon at which gravitational time dilation would be the 64 000 slower than the earth time flow.

[@matiasd.7755]

2:14 About the gravitational redshift, how about person B shining the same green beam towards person A? Wouldn't person A receive a huge amount of energy/radiation in that beam? What about the light of the stars reaching a planet with such a strong gravitational redshift effects? Shouldn't the planet be at extreme temperature?

[@lovritos757]

Interesting question

[@matiasd.7755]

@@skysheep747 i'm not sure about that. It's not relative to only the distance and mass but we also have to account for the extreme time dilation. In the reversed example I gave, the laser would not redshift but it'd "blueshift" instead. Person A would be receiving thousands of seconds of laser light from person B in just a second in person A's clock. That's a lot of power that becomes into heat. Same with the light coming from the distant stars, years of Star light in one hour on the surface of this planet...
