[@vladik19971000]

Consider this: when you were 5 years old, living from age 5 to age 6 meant experiencing 1/6 of your life. However, when you were 19 years old, the span from 19 to 20 represented only 1/20 of your life. By the time you reach 59 years old, living from 59 to 60 accounts for just 1/60 of your life. The conclusion is that as you get older, each passing year constitutes a smaller fraction of your entire life. That's why it feels like time is passing faster as you get older-it's not that time is speeding up, but rather your perception of time changes. Each year becomes a smaller fraction of your life, making it seem shorter in comparison to when you were younger.

[@lethalwolf7455]

Very interesting perspective

[@RC-qf3mp]

Doesn’t account for the phenomenology of life and what it is you’re actually doing. Kids don’t remember much of their lives, and then there’s a salience to all kinds of new experiences. Adults with dreary repetitive jobs feel a passage of time different from somebody in a war zone, or a farmer who works his land and saliently experiences each season. And compare all those to somebody who spends much of their adult life on the sofa playing video games or otherwise attached to screens. The phenomenology of time is also disputed by ‘flow’ states of optimal performance or being in the Zone. Fulfilling moments. There’s a radical difference in time experience when out in the wilderness on a thru-hike where day after day you’re in a remote area and detoxed from mobile phones. A long walk in the sun can feel like a week, or a long walk in the rain. The mathematics of percentages as we get older doesn’t even come close to capturing the diverse ways people can experience time and, so, their lives.

The most insane fact was that the guy staying back and remaining in space did not go insane and flew away, leaving people stranded. Humans are fickle.

[@scottturner1504]

Yeah they got back and opened the door and he said he sat there 23 years

[@paulkirby2761]

Which is a total bs scenario given how he would have seen what happened(albeit playing out painfully slow), understood they weren't going to get back for decades and therefore he would have rightfully left them behind. Don't forget he himself was also subjected to time dilation being also very close to the event horizon, but just not as severe as the cooper expedition so as he left orbit of Millers planet he could have gone back and reported what happened and in the many more decades of "normal time" away from the black hole another expedition could have, should have and would been sent from earth, including placing an AI controlled rescue vessel in orbit of Millers planet for whenever Cooper and his crew finally returns from the planets surface. So all things considered, this man was stupid to remain there and realistically wouldn't have nor needed to have.

[@jerometruitt2731]

You know people dont really go insane just because theyre alone right? Its a common nonsense trope that doesn't really happen irl. Humans are more resiliant than that.

[@paulkirby2761]

Also this man could have switched to an orbit trajectory around the planet rather than around the black hole which would have somewhat equalised his time to their time. Sure, Cooper and his crew may have reached orbit to find this man and ship were now in orbit much closer to the event horizon than they are on the other side of the planet furtherest away from the black hole, which would take decades relative to their position to meet him, BUT, not if they then move to intercept it and the spacetime would equalise rather quickly as they get closer.... ya the whole scenario is bs though and as touched on in this vid, such extreme gravitational and centrifugal forces would absolutely shred the planet unless it was... Pffff... neutron star levels of density lol, in which case you don't approach for many obvious reasons!!

Contact and interstellar are my 2 fav movies. My brain can’t wrap around a lot of these concepts but it’s still fascinating

[@philsurtees]

Why would like a hard science fiction movie and the most idiotic piece of fantasy nonsense ever made? Contact is trying to show what could potentially happen if we intercepted a message from an advanced intelligence, whereas Interstellar is fantasy rubbish about people coming up with an idiotic solution to a problem which could never happen, with so much impossible science, magic, and plot holes in it that it's impossible to take seriously. I mean ... the overall message of Interstellar is that you don't have free will, but it's one of your favourite movies???

The thought experiment behind it is fascinating. Did I explain that simply enough?

[@dannydetonator]

@philsurtees Besides tastes and quality of filmmaking, free will is not a scientifically proven fact. In fact, many scientists lately deduce that true free will doesn't exist (try Sabine Hossenfender). This might be the hypothesis picked up by Interstellar. It's not a hard sci-fi by any means, but attempts at portraying conterintuitive relativistic concepts are done better than any other i've seen, despite the glaring impossibilities. It's for general public and less stupid than average US entretainment sci-fi.

[@philsurtees]

No it isn't. It is WOEFULLY bad. It isn't even science fiction, it's fantasy nonsense. There is no magic in science fiction. At least Star Wars gives the magic a name and puts some rules around it, whereas Interstellar just pulls any old magic out of the hat whenever it's convenient. It is EASILY the worst, most ridiculous piece of fantasy garbage that has been made in DECADES. The tragedy is that so many people are so ignorant about science that they actually believe it is a science fiction movie! That's without mentioning all the plot holes, the schmaltzy dialogue, and the fact that the overall message is that we don't have free will. How on Earth can you enjoy such mindless trash??? You think it's special because you hadn't heard of time dilation before? _"Love is a force,"_ said Coop, before he crossed the event horizon, after which he sent a contradictory message to his past self, and used magic to make the second hand of a watch tick out complex mathematics for 20 years. _HA HA HA!_ Utter garbage...

I recently suffered a brain infection and for a period of time my heart stopped and I died. Around the week of this happening I experienced many strange visions, dreams and hallucinations. One thing particularly strange and disturbing was that I experienced different time zones. I experienced a place without time and I also experienced time slowing down to an unbearably slow rate here on earth. My experience of 1 minute was about an hour. I was observing people around me moving extremely slowly, and the sun rising over a period of about 10mins, but for me it felt like about 10 hrs... It was honestly the most excruciating and horrible experience. This was just the tip of the iceberg of what I experienced, I was lucky to survive.

Seriously, because when this movie came out, we had never been able to actually capture what a black hole looked like & could only speculate. But then almost 10yrs after the movie came out, we finally managed to take a grainy, fuzzy picture of one in real life... and it looked EXACTLY like how they had depicted it in the film! The real life picture is facing the black hole at a different angle from what we see in the movie, however, when you adjust what is shown in the film & peer at it looking down from the perspective of it's "North Pole", if you will... the movie got it PERFECTLY accurate. Nolan spared no effort in making sure to give the audience something very accurate & also very special. 🥲🪐🕳

[@kipo8454]

Time Dilation is such a scary and screwed concept. I will never forget the time dilation in the book "The Forever War" since it was the main point of the book showing the reader the problems that comes with time dilation when entering a galactic war. Watching all your comrades die just to return to earth and see humans evolving into a utopia and that the war ended hundreds of years ago even though you just fought a bloody battle a few days ago was so sad. Still one of the cutest and happiest endings to a book I've read though. (Won't spoil that bit)

​@@dudewrapsupremeNo, not necessarily. He assumed that as soon as the big bang happened, the black hole is formed along with the big bang. However, his assumption is is based on an incomplete knowledge of the big bang.

[@james_win]

You would have to make a few more assumptions, but one that I can think of is the time it would take for the micro black hole to consume enough matter to reach its current size. And if micro black holes don't exist, then you need to account for the time it would take for a star to form with enough mass to collapse into a black hole and the time it would take for the black hole to consume enough mass reach its current size. There are assumptions that needs to be made to get a more exact time, but i am not sure what those are atm.

[@manichaean1888]

We should start with the fact that such planet would not be able to exist in such a close vicinity to the black hole. The planet and everything around it would be shredded into pieces.

Nice video! I hope one day someone can answer MY burning question from Interstellar: why Murph’s family (which is also Cooper’s family) acts like he’s some strange weirdo they want nothing to do with when he shows up literally out of space and time. They MUST know things about him. It makes no sense.

[@sunitamosesesq]

Tell me about it!! I always think the same thing. It's so strange. I get that Murph is way more famous than Cooper ever was... but still. Everyone has to know about him. But they treat him like a nothing. And to add insult to injury -- he has to STEAL a spacecraft to go find Amelia! Rather than them stocking him up nicely and sending him on his way. It makes no sense.

It's really hard to wrap my head around this type of physics. We can't all be Einstein. It's mind boggling to think there are possible scenarios where you could end up being much younger then your children once back on earth.

[@leonhardtkristensen4093]

I really don't think it is that hard to grasp that time goes slower when moving at speed. I have had a lot of thought about how it could work on a very small scale as on the atomic scale or even smaller. The following is my explanation. If you think about a particle as a circle or ball you would not be far from the truth. If this ball has anything measuring time I can only see it to be an electromagnetic signal (EM signal) going from side to side and then back (oscillation between the walls). EM signals can at the most move with the speed of light (near 300,000 km/sec) so it will take a little time to get across from one side to the other. It will take a little longer if the particle is moving in the same direction. (Remember EM signal speed is NOT added to the particle speed as a ball speed would be to a moving car as this would break the maximum speed possible (any speed added to 300,000km/sec would be more than 300,000km/sec.)) Also speed radar wouldn't work. If you do the calculation (as I have (hopefully not wrong)) then you will find that the forward time takes longer than the two speeds added together would suggest and even though the reverse time is much shorter the total will be more than it would be if at stand still. My calculations validated the time dilation formula so I suspect I did it right. It also shows that even though Einstein (and explanations about time dilation) always show it with a light clock going perpendicular to the travel direction then it works equally as well if the time signal goes forward and backward along the travel direction. If you then have that very fast travel slows down time a lot for the traveller then it is not so strange that he will be younger than people left behind and this is really not much different to that frozen meat last longer (kind of stays younger) than fresh meat. That acceleration has anything to do with it as well (except you must accelerate to get a faster speed) as some people postulate I can not see. As I see it it only has to do with speed. Personally I have some problems with relativity. I find it easier to believe that these calculations would be the same for every body and every thing so that we have the fastest time at an "absolute stand still" and not that we can arbitrarily pick our own spot as stand still.

[@amllemans]

I dont understand the difference between orbiting millers planet and landing on it? If times dilated do to the black hole, then what difference does landing on it make?

How does quantum entanglement work with time dilation? I'd like to hear an explanation of how simultaneous events between coexisting particles occur when time dilation is a factor between the two.

[@daemonthorn5888]

1:42 If there are any physicists reading this, please chime in here and shed some light on things. And please correct me if I get something wrong. Would the laser experience red shift to this degree if it is traveling between two stationary objects? I thought red shift occurred when, either, the source of the light or the observer are moving away from the other. And you get blue shift if you or the source of the light move toward one another. I remember reading something about astrophysicists being able to discern a star's movement, toward or away from us in their orbits, by the way the light from them changes from blue shift to red shift and vice versa. Is this correct? And, if so, would a laser beam fired from a stationary location to a stationary target, experience any red shift? I would think the answer would be, "No.". Red shift is a lengthening, or stretching of the beam, caused by the source of the light and/or the observer moving away from the other. I imagine the light "losing energy" over distance,though, similar to sound growing more faint over distance. Sounds get weaker over distance but don't experience a "Doppler effect",unless there is movement by the source of the sound or the listener. I realize that two objects floating in space,like shown in the animation, would be technically moving due to universal expansion. But I'm not talking about the narrator's two astronauts floating in space. I'm going by his words. Which made me think of this question; Would a light experience red shift if it was traveling from a stationary location to another stationary location? With no change in the distance between them caused by expansion of the universe, or anything along those lines. Two,completely stationary, objects, with a laser beam shining from one to the other.

The last scene of interstellar. Cooper takes spaceship to find Dr. Brand. What happened to dilation? By the time Cooper's round trip from the black hole, and back to earth. That took 200 years. So, Cooper traveling to find Dr. Brand, 400 hundred would have passed. Time dilation happens as you travel in space. Once l you leave earths gravitation, time for you slows down. The GPS satellites clocks have to be recalibrated because of time dilation. "That's Relativity.." Remember on Miller's planet it was about 20 years. When Cooper made it back his daughter, she was very old, as in the twin paradox. Cooper said goodbye to Brand when they both orbited a horizon of a black hole. Cooper should have been "spaghettified.

[@Damo-np7ul]

@@wplg Time dilation is relative not absolute. Travelling in space does not by itself cause time dilation, there are situations where you could leave Earth's gravity and time would run faster relative to Earth. According to theory, time dilation is caused by relative differences in gravity and/or velocity. A person living on the 20th floor of an apartment block for example ages the tiniest bit slower than someone living on the ground floor.

Two questions... 1. If Cooper first sent the msg 'stay' then why did he go for sending the co-ordinates 2. Cooper fell into the black hole. How is it possible that Dr. Brand is shown of the same age as his, when he returns to the space station.

1 Hour near gargantuan equals 7 years because of heavy gravity. Does that mean if we go to a place with low gravity, 7 years there would be 1 hour on earth?

[@matics2808]

So wouldn’t it make sense for humans to live in deep space, far away from any gravitational pull? What would time do then? Would humans live forever or maybe thousands of years? Or would they have to live near a black hole for this effect? Such a fascinating topic.

Dude, you're a genius. This is why we can't hear anyone. Everything is red shifted. See it like this. If you sent a signal keyed to hydrogen, by the time it would arrived it would be red shifted to static. We need to shift them back to green.

[@paulkirby2761]

Love this movie(though rarely watch it Interestingly). One obvious contradicting plot hole is the ending where Cooper leaves to find Brand who's described as being out there waiting for him alone on a planet and is shown on a planet doing exactly that while his daughter is kinda narrating it on her death bed(that scene absolutely cut my heart in half btw. 😢) The problem here is that when Cooper and Brand separated close to the event horizon, Brand would age more and more quickly as she moves further away from the black hole while Cooper falls further into it... see where I'm going with this? Even though Cooper would have made that transition into the black hole faster than it would a signal to reach his brain(and thus wouldn't have noticed) and would have also entered the black hole unimaginably quickly from Brands perspective, the resulting time dilation would still have translated into a notable amount of time. So it's just not possible that after that scene Brand and Cooper are similar in age any more. Here's the thing though, the movie doesn't actually show Cooper ever finding and reuniting with Brand. In fact, his daughter seems to have been kept in some sort of stasis in order to prolong her life an unknown number of years beyond her already natural old age in the hopes that her Dad Cooper would keep his promise and return to her(getting tears again!)). So it's possible that while Cooper fell into the black hole and was doing his communication with his daughter, Brand lived and died on that planet alone before Cooper exited. Plot twist. In all the time Brand, and certainly Cooper were in that system losing decades of "regular" spacetime messing about with their black hole buddy, it's highly unlikely that no other teams were sent strictly to check out what's happening and report back ASAP. It's not clear how many years were lost simply travelling from planet to planet, but the poor guy who had to wait above Millers planet could have probably gone back to earth instead of waiting for a decade staring down at static looking people. A new fresh team would instead be the ones to meet them... anyways great movie.

*Update:* feel free to double check, but according to my equations a (rough) estimate of the gravitational force on the surface of Miller's planet & assuming Gargantua is a non-rotating black hole equates to: 1.52 x 10^6 m/s^2 which is about = 155,000 times the gravity of Earth's surface.

[@whichgodofthousandsmeansno5306]

I think the term "alternate" makes more sense then "parallel" in this context. Falling into a black hole and ending up behind the bookshelf of your daughters room is interesting for a sci-fi movie but so far fetched. However, there is paradox to the universe/life and multiverse theory may be the only one that offers viable solution. Infinite, and possibly eternal.

[@bobon_kabalmay]

Time dilation is also known in Islamic science: One day 1:1000 (one to a thousand), or 1 day of the afterlife = 1000 years of earth time. If 1 day = 24 hours, then: 1 day (24 hours) of the afterlife = 12,000 months of earth time or 1000 years.

[@korporalkarrot]

One thing I have not seen answered satisfactorily about this movie, perhaps someone could help. If the gravity on the planet was so extreme as to slow time that much, wouldn’t it have been too strong for them to stand on? If it’s just dramatic license that’s fine, I just want to know.

[@FatHeadDave]

I will try my hand at answering this but I'm likely wrong. The gravity felt on the planet is proportional to the size and mass of the planet (I believe) The strength of the gravity created by the sheer size and scale of the black hole is effecting space time, the bending of space. Each are independent of one another Example, the gravity pull between ourselves and the sun is independent of one another. Anyway, I am likely wrong but thought I'd give it a go whilst I eat my breakfast haha!

[@SweetShakes]

Not a physicist but very into the topic. The huge time dilation is a result of being in close proximity to the black hole, not the planet. The planet, like all mass, causes a bending of spacetime that results in a gravitational pull. But as you said, it’s weak enough for humans to stand on and even escape from, given they have the velocity to do so. The important point, though, is the proximity of the planet (and thus the characters) to the black hole. The mass of the black hole causes enough of a spacetime bend to severely distort time around it (from others perspective), an effect which increases as you get closer. If you’re on a planet that’s orbiting the black hole, you will still only feel the gravitational pull of the planet, while both you and the planet “experience” time dilation from the black hole. Edit: I put “experience” in quotes at the end because, from your perspective, time always ticks forward at the same rate. From your perspective, the universe farther away from the black hole appears to fast forward.

That was awesome. I still am trying to figure out why time can be going on in different places at different speeds but i think we need a universal clock. Maybe one of the furthest distances galaxies (the past) could be used as a standard time.

[@mikolajtrzeciecki1188]

What about speed? No one mentioned how fast Miller's planet is going around the black hole. I think it is plausible

[@mihalis55_33]

So technically there’s somewhere in the universe that humans could live forever depending on how fast we are moving

[@butterflyeffect-q7r]

They wouldn't feel like they're living forever because of special relativity

[@RedNomster]

7:40 It wouldn't require much at all. The movie doesn't stretch any laws here for film making. To the crew on Miller's planet, time is passing like ever before. The "extra energy" that it would require doesn't equate to more propulsion needed. It's all relative. Just like how the Earth and the moon are almost exactly as far away from the sun, trapped in the same gravitational well, but it's takes virtually no effort to launch from the moon compared to earth. Miller's planet is the same, but instead of the Sun warping spacetime that guides the planet, it's a blackhole. The size of the blackhole also determines how close you can be before being "torn apart." In some cases, you'll be spaghettified. In others, you'd be able to physically cross the event horizon LONG before being spaghettified. It's clear Miller's black hole is the latter :)

Gravity ratio proportional of mass and volume , Gravity carry Time and slowing Time when more gravity force occurs on more mass, so outer layer low energy band having time that's protect gravity ratio of planets. Every molecule have it's own time.

[@GordoCooper-v3v]

To travel back in time on earth one merely has to travel faster than the speed of the earth's rotation. Essentially if you could leave your seat, travel around the earth faster than it rotates you arrive back at your seat in an earlier time. The crazy part is, it's not faster than the speed of light...

[@nilesn9787]

Here is a question. Does time dilation effect the edge of the observable universe relative to us. Considering all the mass of the Universe was more concentrated in a smaller aria. Or with space itself contracting, who knows.

[@nilesn9787]

Or maybe the expansion isn't happening now but was happening then.

[@Cbricklyne]

RE : Extreme time dilation Um......so what was causing the time dilation difference in the passage of time between the astronauts on Miller's planet and the astronaut they left behind on the ship orbiting the planet? Weren't they BOTH inside the black hole's gravitational well that was causing that extreme time dilation difference between them and the rest of the universe? The guy on the ship aged more and experienced more passage of time than the people on the planet who only experienced a couple of hours. How the hell was this so? They were both orbiting the black hole at roughly the same orbital radius. Furthermore, if the black hole's gravititional well was such that it cause such an extremet dilation in the passage of time, then how the hell did they muster the necessary thrust or propulsion to make escape velocity to leave that star system? There are more ludicrous aspects of the movie regarding the plausibility of a habitable planet orbiting a black hole and whether such a planet would even be viable for human settlement (like the fact that that planet would almost certainly be tidally locked to the black hole in order to be in the black hole's "goldilock's zone" - and you know what it means for the possibility of the existence or development of life on a tidally locked planet. Or the likelihood of super-high radiation levels emanating from the Black Hole's accretion disc and the source of heat and light in the system compared to what a regular sun-like star would produce.... Why people worship this movie as the scientiic masterpiece it supposedly is, without bothering to ask basic questions about the so-called "science" is beyond me. At least most (actua) astronauts and astrophysicists I've heard commenting about the movie think it's a silly movie.

[@johnavi]

With an infinite universe, where I'm writing this an infinite amount of times with slight differences, could I be constrained by a different set of laws governing the universe? Am I in any way connected to those iterations of myself typing this sentence? It's creepy to think about. Could this in any way be responsible for our perception of time?

[@musamnguni510]

I remember watching this scene back in 14” and being marvelled by the waves 🌊 caused by gravitational pull of the Blackhole but also shocked at the insane time dilation stated . It really blew my mind away. Also the fact the at millers death occurred hours prior to cooper and the team arriving was a shock on itself . What started to not make sense to me is why the time dilation started to not matter as Cooper fell straight into the black hole . Why is it that eons of time had not past when he came out the tesseract. Also were you see coopers craft fall in and the stars and galaxies start to zoomies into an infinitely small light why couldn’t he see time speed up behind him and basically see the universe evolve ?

[@V3racious3]

Light doesn't lose energy, the streching of spacetime stretches the wavelength.

[@jamesstaggs4160]

According to the law of conservation of energy time travel would be impossible. We've all heard "matter cannot be created or destroyed" and travelling to the past would "create" matter. Let's say I bought a shirt from a store ten years ago. I put on that shirt, hop in my time machine and travel back ten years and one day. I visit the store where I bought it and there's the shirt hanging on the rack, but I'm also wearing the shirt. Now two shirts of the exact same material components exist, so I've created matter. That actually goes for anything. The "stuff" that makes up your body will have existed in different forms in the past, so you'd be making copies of that matter if you traveled back in time. Even sending a single atom of hydrogen back five seconds in time would create matter. All of the above assumes that we and everything else exists in a closed system. As far as we can tell this is a closed system but if it isn't then it would remove the matter creation issue from time travel. Let's hope it is a closed system and that time travel is impossible because it only took me a few minutes to think about lots of ways to abuse the matter creation part of time travel and you know there's plenty of people who wouldn't just think about how to abuse it.

[@shempshempleton4746]

It's not creating more matter, it's moving the matter to a "different" "time/location".

[@6desk]

My favorite all-time movie & you covered some fascinating perspectives of the movie.

If people think that a black hole is a still object that pulls things in as they fly by is wrong and off, in reality they're moving objects flying yhrough empty intergalactic space as if it were a fluid. When they fly through ionized gas they pull it in to a vortex. But the idea that a black hole will pull you in deep to a singularity is false. A black hole will stick you to the edge of itself. Too much density. So if you enter the hole you'll change state. You won't be the same matter you were once you get in near enough to it. Time slows because density slows entropy. Think about it, a dense cement wall is hard to heat, if you compress that, its even harder. Heat, the BTU, the calorie, and everything we associate with time stops inside the core. No molecular motion. Absolute zero temperature. Its a matter of ultimate density. The core is made out of subatomic particles BOSONS can be compressed beyond imagination. Matter so tight that motion and changes of state become impossible. You cant cook or boil them like we're used to. Remember what they do to stars, and stars control our entire planet, the black hole is a super packed star that condensed/collapsed, and for all intensive purposes has become a SPACE PROPANE CAN. It's fuel, mass, energy in matter form. Add enough pressure, nothing can get out, too stuck, too frozen, frozen way down deep inside the building blocks.

Nice, love that film and enjoy hearing about different aspects of it. Also time dilation occurs if you approach the speed of light (with respect to your origin I think) or just go fast enough away from it. That's another energy problem though.
