Einstein discovered this theory in his mind without the internet. I have the internet at my hands, I've watched this video twice and am still struggling.
time dilatation can be observed when your wife says she needs 5 minutes to get dressed. On your watch it passed 45 minutes, but for her it's still 5 minutes.
For those who don’t understand why moving really fast makes you slow down time: Light must remain constant, let’s imagine you’re practising for a race with a photon who travels at -300,000 kilometers a second. You’ve trained really hard and you think you might be able to get close to the photon after getting a new personal best of 299,999 kilometres per second. You and the photon line up for your big race, everyone’s watching! You run your hardest and reach 299,000 km/s, but wait, the photon should only be travelling 1,000km/s faster than you since that’s the difference in your speeds. But instead, the photon is still travelling 300,000 km/s away from you. How can this be? Does that mean the photon is travelling faster than the speed of light? I cant tell you why the speed of light must remain constant, just the way it is. But how does it seem to travel as fast as you at 299,000km/s plus an additional 300,000km/s, that’s faster than light speed, which is impossible! What actually happens is the time you experience is slowed down enough so that relative to the photon, you’re actually stationary and it’s just zooming past you as if nothing is happening at all. This is because light doesn’t experience time, from the perspective of a photon the universe has started and ended in an instant. If we were ever able to travel at the speed of light even for a nanosecond, then the extreme time dilation would zap us into the end of the universe, literally instantaneously. This is what annoys me so much about people wanting to travel faster than light, like yeah, great idea, you’ll certainly find out if there’s a God if you do.
Nothing can travel at the speed of light except light. As you accelerate in space, you lose mass. By the time you get to SOL, there is no mass left to push against. You can delay the mass to energy conversion process by cooling the atoms being accelerated (atomic clock, for example). At some point, though, the accelerative forces cancel out the cooling forces, and mass destruction begins. A photon doesn't experience time because it has no mass to accelerate. It does, however, experience space and collects information along the way that is imparted into the detector at journeys end. Time within the Space frame is just information. No atoms actually exist outside of the present.
Great comment, I think it helped me understand, but a question if you do get this, does that then mean that light has infinite speed, but because of the fact that we can only measure light because of time, that time itself it the limiting factor in it's measurement? Gonna break my brain, so for example say you have a vision of 100km, at one end you see 100km, straight infront of you, but if you move 150km in, you will now see 100km to your left and to your right, this is of course assuming a 2d universe or whatever, by moving in we are changing out measurement position, so we can see more, but the rule has not changed.
@nineonine9082 light has a propagation rate. It's speed is based on the permittivity of space. Permittivity is electrical energy. To have infinite speed, you would need infinite energy. You are at the center of your visible universe. Since the permittivity of space is essentially uniform, excluding black holes and such, your visible universe is a uniform circle around you. Stationary objects drop in and out of your circle as you move about in space.
I dont get really get this.. on what basis do you say that the photon will travel 300000km/s away from you even when you are travelling at 299000km/s.. pls bare with me here ive just been introduced to all this
@@xaviermax4788 the speed of light is ruled by the permittivity of the space in which it travels. Permittivity is electrical energy. Speed is how fast a wave can be propagated. The length of the wave determines the distance the photon has to travel in order to propagate a new photon. When you move away from the propagating source, the photon has a longer distance to travel. When you move towards the source, the photon has less distance. Time-dilation is the effect of your speed by Y and the photons speed being X with respect to the motion of travel. If one person is standing still, throwing balls at a target moving away, the ball takes longer to reach its target. For some unknown reason, maybe it's because the target is a counter, this fundamental aspect of physics has become known as time-dilation. If you move a block further away from work, is that called time-dilation because it takes no longer to get to work. How about moving away from a broadcast radio station? When dealing with the speed of light, you are dealing with the time-dilation of information. Your actual time is still progressing at 1 second per second. Since the laws of physics are equally valid in all frames of reference, acceleration in space (change in spatial coordinates) also causes and acceleration in time event. How much acceleration is determined by the mitigating factors. The cesium-133 atom of the atomic clock is chilled to absolute zero to prevent it from being accelerated in time when a force is applied. This makes the clock an instrument for measuring acceleration in the Space frame. Acceleration in the Time frame will vary based on the force being applied to that frame of reference and how the mass of that frame reacts. The denser the mass is, the more force is required to accelerate it in time, time being converted back to and from radiant energy. E=mc. Atomic energy is converted to radiant with acceleration. F=ma primarily deals with acceleration in space. E=mc, acceleration in time -> change in the structure of the mass. Mass can be radiant energy (electromagnetic waves), Atomic energy (animal, mineral, vegetable) or information (body of knowledge knowledge). Electromagnetic waves are force carriers. What do they carry? Information. F=ma. Force equals Acceleration The fundamental law of the universe. If you understand that, then you understand the universe.
What I understood is that the faster you move the slower time is for you, the more sever the gravity of a planet the slower time is, that’s it for me 😂
I had struggled with this for years, despite being a physicist and engineer. The problem is that the thought experiments on this topic are fallible in many ways, if taken too literally. [For example, what if the clock tower was on a train moving away at the speed of light from a stationary observer, or if the observer was on a train that started on an approach to the clock tower, then continued past at the speed of light?] For me it took a completely different perspective to understand it, building it up in stages: 1) If every particle in the universe was static with respect to each other, there would be no interactions, and it would seem time had stood still, because nothing is changing. For time to become apparent, particles need to move and interact with each other, energy has to flow. 2) The speed of light is a universal constant. Do not consider light as an object, like a ball moving through space. It is a limit on how fast events in one region of space can cause events in other regions of space ("causality"). 3) If you were travelling at the speed of light, the atoms and particles that make up your body would not be able to move in the direction of travel (relative to the centre of your body), since they would have to travel faster than the speed of light (violating causality...the outermost molecules of your body would arrive at your destination slightly before you should be able to arrive!). Hence all the particles in your body would actually be static relative to each other, and therefore you wouldn't be ageing. Furthermore, you wouldn't be able to have a conscious appreciation that your ageing had ceased, since even "thinking" would require movement and interaction between the particles in your brain. 4) Since any object's perception of time is relative to the "relative interactions" of the matter it is made from, it cannot perceive the difference between a tick (at zero speed) or a tick (at near the speed of light....a "tick" is a "tick" according to the object observing or recording its own time. Due to the principles of a universal speed of light and causality, moving through space will necessarily slow the mechanism of the moving clock, and by an equal amount, the mechanism by which the moving observer is able to observe the clock. A clock moving through space actually does tick slower than a clock not moving through space. [A profound thought regarding point (2): If the speed of light is measured by causality, and causality infers change, and change infers the passing of time....if time didn't exist, would there be a speed of light? Would there be light?] In the context of this perspective I can go back to the original thought experiments and understand which aspects of them are useful in deriving the maths. These are all my own thoughts. I don't know if any professor of physics would validate them. But where the original thought experiments left me feeling dissatisfied, this new perspective helped me.
My question to someone who understands time dilation and speed of light is...photons move at a constant speed, no matter how fast the observer is traveling. Light still travels at 186,000 miles per second. So what if I'm moving at the speed of light, and I shoot a photon from a flashlight. Are me and the photon traveling at the same speed side by side. Or does the photon shoot off at the speed of light? Well it can't because then it would be going twice the speed of light to someone stationary. So I assume if I emit a photon while I'm traveling at light speed, then the photon would look stationary to me
@@johnarthurflores3098 time exists but at the same time doesn't, people just needed to come up with what to call the progression that's happening in space also feel free to whoosh me
Really fascinating. One thing I personally find interesting is the discussion of time relativity in the Quran, which was revealed about 1400 years ago. It discusses, for example, how time is experienced differently in the different ‘skies’ or ‘dimensions’ of the universe. It’s mentioned that there are 7 such ‘skies’ or ‘dimensions’ (in fact - we’re told the observable stars belong to only the first sky/dimension). For example, one verse translates roughly to: “He arranges [each] matter from the heaven to the earth; then it will ascend to Him in a Day, the extent of which is a thousand years of those which you count.” [32:5] I find it very interesting, especially given it was revealed about 1400 years ago :) If you’re interested in learning more don’t hesitate to ask.
It has always blown my mind thinking that “time” isn’t an abstract concept, but an actual real physical thing that can be influenced by motion and gravity.
You’re right, because an invisible sky daddy who loves you but will burn you forever if you don’t love him back makes a lot more sense than general relativity.
Or if I allowed relativity to shape my metaphysical understanding j could be lead to believe that the human race descended from the incestuous union of eight people after they got off the ark.
THEORY OF RELATIVITY VERY EASILY EXPLAINED Light Travels at a specific speed. When he watched the clock tower, the light that entered his eyes allowed him to watch the clock so if he travelled at the same speed of light, the light would never catch up to him so he would see the same position in the clock. Credits: Wiktor Kasz (This is a copied comment)
A long long time ago, I remember being told in the 5th grade of the 3 dimensions and then hearing my teacher say "some people even say there is a 4th dimension". On the way home I told my dad, "If the first dimension is height. Then length, then width....then the 4th dimension has to be when that object exsisted.". So I like to tell myself I theorized space-time as a child. (I mean, not really but close enough lol)
That is nice. when he traveled away from the clock tower at the speed of light the clock stopped. Then you must realize that is cus of the light waves emitted from the clock would not reach him cus he is also traveling at the same speed. so he will only see a snapshot. then how he can tell that flow of his time slowed down by that experiment according to this video?
@@ceylongamersleague9733 Its all a matter of different frames (of reference), to someone inside a bus, he isn't moving so he he sees himself at x=0 (the orgin) always. So to him time is/appears slowed down but to the res of the world, time passes at its normal rate. Also he observes things outside of his stationary frame, ie not stationary wrt to him/his fram, to be of shorter lengths than the world around him, starionary to everyone else and where he seems to be moving at relativistic speeds x approaching c the universal speed limit, 299 792 458m/s
I feel like giving you a hug. Not many children have this authentic zest for science. Children are so special they should be exposed to more science in their lives, they’re little geniuses and they don’t even know it.
Because it was theorized that speed of light always remains constant, even in a relative frame. If you travelled at say 50% the speed of light and cast a beam in front of you, light would still appear to go at 3×10⁸ ms in front of you. This is what was contradicting Newton's laws of motion.
If you were to travel towards an observer/object, the time dilation effect would be the same as if you were moving away from the observer. In other words, the time dilation effect is symmetrical, and it does not matter whether you are moving towards or away from the observer. The only thing that matters is the relative velocity and gravitational potential between the two objects. For example, if you were on a rocket ship traveling towards an observer at a high speed, the time dilation effect would be the same as if you were on a rocket ship moving away from the observer at the same speed. In both cases, time would appear to pass more slowly for you compared to the observer, due to the difference in relative velocity and gravitational potential.
This channel is perfect. No music in the background, so I can perfectly listen without distractions. In the description is all authoritative academic sources.
@siddharthsriram2685 time is the same where ever you are and how ever fast you are travelling, unless there are electromagnetic fields that might affect an electric clock and thus time might slow down or speed up
This wasn't a very good video, so don't blame yourself. You need something a bit more complete and better organized. This video is just giving some thumb nail sketches of the basic points.
@@keimoji I get the speed relativity but how does that affect aging or time? Like if there's 2 people, one on Earth or in a certain point in space. Person 2 wants to travel to another point, and it is exactly 1 light year away from person 1. So it takes 1 year to get there at the speed of light. Then person 2 goes back to person 1, so another light year. That's 2 years that should have passed, for both. Yes, person 2 will see that everything is slower, but that's only relative. Ageing and metabolism wouldn't change, so I don't get how 2 would have aged slower.
@@Shvetsario This isn't a good video but I think the answer to what you're asking is that 2 years won't have passed for both people. When person 1 waits 1 year for person 2 to arrive, person 2 doesn't experience 1 year. Because they are travelling at the speed of light, they would only experience a fraction of a year (as time is moving slower for them). So relative to person 1 they travel the same distance in much less time. Another way to think about it is; A Light Year is the distance it takes light to travel in one year from the relative perspective of the stationary observer.
Time dilation has no significance for time travel in physical plane. It actually indicates the depth of space-time while observation made on speed of light is a projection at the surface. And time dilation said to be due to gravitation is also not true, it indicates the difference in levels of crests and troughs along the surface of space-time.

Me falling out of an airplane: AHHHHHHHHHHH! Einstein: Notice how his photon clock is creating a triangular shape due to the stretching the duration of a second.
@@diphenhydramine6072 Then please answer this question. I understand that for a person who is travelling at the speed of light away from the clock, it would seem that the clock is not moving. But let's assume that the same person travels to a fixed point and then starts to return to the clock at the same speed. Then the clock would move at twice its normal speed. Does this mean for that person time moves twice as fast too?
The fact that Einstein thought about this experiment and could accurately predict it’s result without even knowing what would happen is astounding If he was alive now,he could probably accurately predict what is inside a black hole and what would happen to human in it😢
what makes physics even more fascinating is that we ourselves probably dont understand even the pinpoint of what it really is. it's caused me to think, what if aliens have much more advanced tech such as being able to move and stop at incredible speeds without inertia affecting them because they have a much better understanding of the laws of physics than we do? what if inertia is a law of physics we can somehow completely ignore?
That's a bold statement. I suggest God is the only one that fully understands physics 😁The more I understand, the more I started to see the infinite power of God. Strange how I found faith through science.
@tommy cane115 Actually it has already been proved by the equation of gravity that scientists use to calculate the force of gravity: Rμν=-1/2Rgμν=8πGTμν
You made it very interesting by illustrating it in a story format. These stories or events behind such inventions are the real gems, which make science interesting. Thank you so much.
assume that youre driving a car which is going at 40kmpr to you it will feel the same as taking a walk opposed to a person who is just crossing the road
This is so true and relatable. If you move faster through space, time slows down for you. If you move slowly, time goes faster. The proof is when I am late for work, time goes annoyingly faster for me.
Amazing stuff; the moment I learnt the speed of light is not about light, but causality, I started to understand causality probably dictates all the experience of space and time we have; and it makes sense (causality is so fundamental; like something needs to actually happen before you see it happens, there’s no way around it); I would even think causality would REQUIRE the universe to exist and exist in the exact way we see; hope some great minds can resolve this
Actually one big flaw about this video is the sentence "The faster you move through space the slower you move through time" and this really confuses most people here cause they get a wrong idea of the concept. Your own time still runs the same for yourself. Only if you compare your own watch to the clock tower you can see the difference and realize that time in your own referential passed slower than the time in the other referential, thus the word "Relativity" cause it's all relative to where you are and how fast you are. So the sentence is not really wrong but it visualizes a wrong idea.
And who is to say I am moving faster than the clock tower?? The clocktower is moving away from me just as fast as I am moving away from it. Relativity right? I'm only moving away from the clocktower if the frame of reference is the earth surface, but earth and the solar system and the galaxy are moving too. So what if I am compensating some of that movement by moving away from the clocktower? I would be moving slower than the clocktower, so now the clocktower's time should move slower. Who is to say what object moves with what absolute speed when all speed is relative? The explanation is illogical and is not thought through to the end.
Working requires movement, therefore time feels slow for the most part. But taking a break doesn't require you to move most of the times, therefore time feels quick.
yes it doesn't because this is bullshit after all. Time is a perception. What's slowing down or going faster is not time but how you perceive it, the more you are aware the slower it goes, the less you are aware the faster it goes. Time is constant, no past or future exist, there is only now, we are the ones conceptualizing those things in our head. One thing i don't like about this is that they assume that if you move at the speed of light you are fully conscious of all the information you pass through, but in reality you won't see shit.
The one part of this that will never click in my brain is the concept of aging differently based on what speed you are travelling, I've never seen that part of the law explained in a way that makes any logical sense at all.. I understand relativity, I understand that the faster you travel away from something (say, Earth for example) then the slower in time it appears to move, up until you travel at light speed where everything you observe back on earth shall appear to stop in time - I get that no problem. What I don't understand is that surely the moment you travel back towards earth at the speed of light, then wouldn't you just observe everything on earth moving much faster now, therefore technically "undoing" the slowed/stopped time that you previously observed..? How is time dilation anything more than a mere observation, how can it possibly be an absolute change in time if you end up travelling back to where you began your journey? I want to make sense of this and have tried for years but I've never seen or heard an explanation that does it justice.
I think it is because you somehow get closer the speed of an unit of time thus,time goes by soo slowly , and space is becoming meaningles compared to people on earth,while everything about space is still same on earth and going on its own pace .For the person on earth to perceive things about space ,there needs to pass more units of time.I hope i could explain what i understood.:)
Maybe because light experiences no time, therefore if you are a massless particle going through the universe at the speed of light, you would have to be light. It’s un achievable to weigh and travel that fast otherwise light would be able to go faster then it already does if that makes sense. I’m no expert
For those who didn’t understand shit The faster something moves, the slower time moves, because you’re moving fast enough that you don’t perceive time as everyone else perceives it
the slower it seems to move. the clock and devices we use to measure time are not time themselves. the clock has no effect of the actual passage of things from potential to actual. if you move the clock back 1 hr, nothing happens to the universe, time is still constant. time just is
This is why fat people die earlier. Joggers spend time running so time seems to slow down for them compared to the fat slob sitting in his sofa. And all this time we thought it was the fat that was dangerous.
@@staneze3972 So what you mean is time doesnt actually freeze or slow if you move at the speed of light in space, time is constant and its moving at its normal speed, so its a perception thing, when you move at the speed of light new light doesnt enter your eyes for your brain to show the present time on the clock so youre basically seeing the clock freeze, but for someone thats near the clock the clock isnt frozen? But Im curious to know what will happen if the person moving at the speed of light suddenly haults? Will he be living in the past and everyone else on earth in the future?
@@lucifer-mp8fc no he won’t be living in the past or the future . You said it beautifully , light wasn’t reaching his eye because he was moving at the same speed as light . He only becomes aware of what was unable to reach his eye. He’s no different than someone that was asleep and wakes to see all that has changed . See, when people say arrive at the past or future what they also miss is this . Time, space and matter are 3 things that MUST happen at the same Instant. If one lacks then it makes no sense , if no space, where will you put the matter and if no time , when did we become aware of it ? Saying someone arrived at the past, he or she must see what they’ve experienced before and for arriving at the future , there is no such thing as “the future.” Our current choices shape whatever happens later in life.
It takes such an incredible imagination and fantastic ideas to derive this. To take such leaps and bounds in thought. I would love to have his brain for a day and just experience his perception, etc.

Same here,🤔 I honestly think there's something missing in this theory. There's something "odd" about it and I'm trying to understand how the math actually came about.
@@callmestern It doesn't make sense at all, trust your gut. I suggest you to watch Bill Gaede(Physicist Professor of Rational Science), he touches on the definition of "exist" and separates the fine line between OBJECTS and CONCEPTS. Time is a concept, it does NOT exist, Time = comparison of two motions (Seconds, Minutes, Hour is a tick on your watch, the movement of one hand to the other)(Day is full spin of earth) (Year Is orbit around the sun) Concepts are just relations between 2 or more objects. For something to exist it must be an OBJECT, that which has shape and location. Time does not have shape and location, and math physicists treat a clock as the embodiment of time which is totally irrational. If we used an hourglass, which is a clock that works specifically through gravity, it would've showed that its the opposite of what Einstein said he predicted. Its not that the clock is faster out there in space, its quite the opposite it runs slower. And if you take that same clock, and you take it to sea level that clock will run faster because it's closer to gravity and the grains are gonna come out of the little glass container faster. So our clock proves general relativity wrong because it has the opposite effect of what they "predict" as its known. They call it a prediction, well here's a prediction, I'll say that my clock runs faster when its at sea level than out there in the middle of space. In fact if you take it further out not a single grain will fall and according to the lunatics of relativity, they would say that time had stopped because they decide everything by measurement. And now if not a single grain falls because there is no gravity out there they say well time has stopped. That's what they would conclude, that's their rationale, that's the way a mathematician thinks. He says oh it goes slower slower slower, and when it goes out there where there is no gravity they say oh it stopped altogether so now time is no longer flowing or it stopped altogether. 🤦
me and you both. I'm 19 too and hated maths and physics at school (and I still hate), what I like about physics is the theories and astronomy, I hate the calculations and formulas. I liked that part of physics while I was still at school but only now I started diving deeper into it
Find the point where science and art are one. True art is said to stop the mind in it's tracks. The mind bows to that which is beyond it's capabilities. Einstein is said to have made his greatest discoveries when his mind was still. A state of no mind was his clearest. The ideas just came to him if I read correctly. They can support each other. They don't have to compete (science and the humanities)
But how does moving slow down the time?? Its just that we move from one place to another quickly !! How does that slow down the time !! Lets say one person is moving in high speed and the other person is standing still ! After a hour if the moving person stops the time is same for both people !!

at 1:13 when Einstein is watching the clock by moving with a speed of light, the time at the clock is actually changing there, but the old light ray is still moving into space taking long way if he travels with speed of light. so the time in the clock tower and the time (in einstein's watch) would be same at any give movement. But if any one calls by phone and say the time, the phone signal would take the time which light takes. so, even then he would not be conveying the exact time. but if (just imagine) one can make phone call which gives information instataneously with infinite speed (which is not practically possible), then the exact time can be conveyed to einstein by phone. then there will be no dilaltion. the time dilation is felt because of speed of light. also at 4:00, the man on the train going at the speed of light, it is told that the time is slowed down for him. if there is a blind man on train, does it mean that there is no lightning strike for him? it's not for Einstein or for man on the train, the happened event is at exactly same time. it's not that time is slowed down for him, light ray is quick on him. at 7:12, for the man on the hill, the photon clock (on the man falling from a height) will actually look moving slightly fast to complete the strike in 1 second. it won't slow down for any one. the example is like watching the Television and moving to the corner and expect to stay away from the gaze of the anchor (which is not possible). time dilation concept is not convincing. I feel it's light dilation..!
The theory becomes less understandable when you watch more videos on youtube and authors explaining their own understanding like it's written on the rock.
I've tried to understand it for a long time and I just can't. Everyone's saying that time dilation is real, but I have no reason to believe it other than "people smarter than you decided it does"
Exactly, it makes no sense, you can't just decide that time must slow down.. All you have to do is think logically for a moment, two people in the universe are always going to age at the same rate. It is not possible for one to age faster or slower based on gravity....
@Channel YT That is the point. They make the speed of light a constant, and get that theory. There are positively other theories that does not grant the speed of light a constant.
Mick0722MX you probably didn’t understand anything during or after the lightning bolt part, it actually makes perfect sense. Modern GPS uses time dilation btw.
@@jakovage9480 I understand it better than you ever will. The only reason it makes perfect sense to you is because you don't know shit in the first place. There is no such thing as time dilation because time itself is just a measurement of motion. The GPS uses a "time dilation FORMULA". A formula doesn't make time dilate. The true phenomenon behind the GPS is that matter is affected by speed with respect to gravity; not time. This is common sense.

You and your friend have two watches. All of a sudden, your watch runs out of electricity and stops. The genius of Einstein was not to call this phenomenon dilation of time.

Thank you for this video, lots of video's do not give mention to the fact that Einstein's final theory does see: the speed of light as a constant. It really is important to integrate that with the general theory of relativity, all things actually do have a speed with respect to light. thats how its possible to know your speed with a light clock, and not a mechanical one.
Right- it can't be understood- because it is illogical and untrue. It can, however, be memorized and repeated- by those who foolishly think they are smart.
Sometimes i wonder who we really are in this universe. But just thinking the vastness of the universe and the complexity of it and the human desire to exploit what’s in it, makes me want to forget everything i learned about science and just have fun and live my life the way i want it to.
If you're a sprinter or know about sprinting, this is pretty easy to understand. The faster you move, the shorter amount of time you use. Also, the reason the earth doesn't roll toward or away from the sun isn't because of fabric being pulled. It's because the earth is rotating/spinning & not rolling. Using their example of a marble, if you spin a marble it it will stay where it is or move in a circle. If you roll it it'll roll. Since the earth is rotating/spinning, it can't roll at the same time. The sun bending frabric & forcing the earth to move in a circle or oval isn't necessary if the earth is rotating.
Wow this was really helpful. I actually understand the entire thing. I'm totally mind blown!! I thought it was going to be impossible for me to grasp this concept, but apparently not. I can't describe how I am feeling right now. This concept has been torturing me for years and I have finally figured it out after two separate physics classes, tons of research, and informational videos such as this one.
Assuming they have a method of calling each other, the call would take years to connect and when it does earth twin would be talking to a past image of planet twin so no real conversation will happen.
You have explained this complex theory brilliantly, regardless of what the first few comments say. I think they're just over thinking, which is easy to do. Come back again in a different time/mood .. you would be surprised at how much easier it is to understand.
An easier way to think of this is to consider the superhero The Flash. When he starts running, everybody around him appears to be moving in super slow motion to the point where bullets are almost frozen mid air. Were he to run at light speed, everybody and everything around him, down to the individual atoms, would slow down to a complete standstill. That’s all it is.
If you think you understand this in one go, you do not understand it al all! (quote from one of the big brained poeple, not me! LOL, I even forgot who said it, and it was told to me just a few days ago.)
I use have a difficulty understanding all these things back on school, 5 years later I am just enjoying a YT video and I have better understanding of everything being explained
At the very beginning of this video, the one thing that is missing, is that Einstein wouldn't have had the time to imagine the hands on the clock seeming to slow down. The fact the he imagined traveling at the speed of light, but was still in real time, allowed him to imagine the hands on the clock moving slower, when in actuality, he would have already arrived at his destination were he traveling at the speed of light. Now yes, the hands on the clock do appear to move slower, but let's say Einstein was having a conversation with someone. He would barely be able to get the words out before arriving at his destination. The hands on the clock would barely get a chance to move. Einstein would be traveling at the speed of light, but his bodily functions would not increase in speed, his heart rate would not increase in speed. His digestive system wouldn't work faster. The only thing that would change would be the speed at which his body was traveling from one location to the other. The functions in his body would not speed up, nor would his speech, or his respiration. If Einstein kept on traveling at the speed of light, without stopping at his destination, the hands on the clock would seem to move slower if he could still observe them from far away. His body would be changing it's location faster, but everything else associated with his body and it's functions would not. If he got up and walked in the direction the trolley was going, towards what would be considered the front of the trolley, the speed at which he is changing locations would increase, but the speed of his thoughts, the rate at which he swallows water, and if he was wearing a watch, the hands on the watch he would not increase in speed. So I don't understand why time would speed up or slow down. It may seem that way because Einstein had the time to sit there and imagine the hands seeming to move slower, but in actuality, the hands would barely get a chance to move at all because Einstein would have already arrived at his location. So the speed of time never changes. The length of time that is measured can be shorter or longer, but the speed of time does not change. If you are standing between two bolts of lightening, the light emanating from the bolts would reach you at the same time. If you were passing by in a train, the light from the bolt closest to you would arrive at your eyes faster, but the light would still travel at the same speed. It wouldn't speed up or slow down based on the speed the train was traveling. Not would time. And the only thing that changes the speed of the train in relationship to the train station would be the train's engine. In the film interstellar, I really don't understand how the people in the ship, traveling at the speed of light, would = their kids growing up faster. And being on the planet with intense gravity, I do not see why that would change time for the people on the planet vs the guy not on the planet. The people leaving the ship to visit the planet would come back whenever they decide to come back, but I don't see how increasing the gravitational pull would change time for them vs the time for the man on the ship . If anything, they would arrive at the planet faster, but would have difficulties escaping the gravitational pull of the planet when trying to leave. Is that what changes time? The fact that it takes longer to escape the gravitational pull? Because I feel like if the guy in the ship could have a phone conversation with the guy on the planet, one guy wouldn't be talking slower than the other guy just because of the gravitational pull of the planet. I guess this is what I don't understand about the theory of relativity. Or maybe I do understand it but I'm thinking it's something that it obviously isn't. Anyone want to explain?
Dude I was already not satisfied with this video, you confused me more by asking a Genius Question ' person speaking in a phone from the planet.....' that was a great thought. But what I think is we are having difficulty understanding Einstein's concept and this whole video has not explained it correctly. We should search for some other explanation to better understand.
That was one of my concerns from interstellar, your feeling of the second does not change, why would time change some where else? A second is a second, it's just a measurement tool, why would it expand and contract in terms of the one experienceing it? That's what I don't understand or comprehend. As you said my friend the ship might need more power because of gravity, and if it's slower it doesn't make it quickly
@@raguravi1659 there are other better explanations, I came across some of them and I have a better understanding of the theory of relativity. They have to explain it correctly. Gravity is equivalent to speed because speed creates G-Force. So I understand that better. Light always travels at the same speed no matter where it is, what it's doing. If you're in a car traveling at lightspeed and you turn the headlights on, the headlights still travel at light speed. Therefore Einstein hypothesized that light is the eternal constant that all other units of measurement bow down to. Speed, time, weight and mass all change, but light does not. It's something to do with that. Equally strange seems to be the ability of larger denser objects being able to warp reality or space-time.
@@jackjones5484 I watched a few other videos and I understand it better now. Gravity and speed are the same thing in the case that G-Force is involved in speed. Time and all the other units of measurement change as you approach the speed of light or intense gravity, because light always travels at the same speed no matter where it is.
I really like the way you explained this video regarding the dilation of time. I don’t know, maybe it’s your calm demeanor that made it all the more interesting. Be that as it may, please don’t stop making these videos 👍🏼

Time dilation in a nutshell
And the funny is when she is done, she gets angry when you need 1 minute to get your shoes
For those who don’t understand why moving really fast makes you slow down time:
Light must remain constant, let’s imagine you’re practising for a race with a photon who travels at -300,000 kilometers a second.
You’ve trained really hard and you think you might be able to get close to the photon after getting a new personal best of 299,999 kilometres per second.
You and the photon line up for your big race, everyone’s watching! You run your hardest and reach 299,000 km/s, but wait, the photon should only be travelling 1,000km/s faster than you since that’s the difference in your speeds. But instead, the photon is still travelling 300,000 km/s away from you. How can this be? Does that mean the photon is travelling faster than the speed of light?
I cant tell you why the speed of light must remain constant, just the way it is. But how does it seem to travel as fast as you at 299,000km/s plus an additional 300,000km/s, that’s faster than light speed, which is impossible!
What actually happens is the time you experience is slowed down enough so that relative to the photon, you’re actually stationary and it’s just zooming past you as if nothing is happening at all. This is because light doesn’t experience time, from the perspective of a photon the universe has started and ended in an instant.
If we were ever able to travel at the speed of light even for a nanosecond, then the extreme time dilation would zap us into the end of the universe, literally instantaneously. This is what annoys me so much about people wanting to travel faster than light, like yeah, great idea, you’ll certainly find out if there’s a God if you do.
Nothing can travel at the speed of light except light. As you accelerate in space, you lose mass. By the time you get to SOL, there is no mass left to push against. You can delay the mass to energy conversion process by cooling the atoms being accelerated (atomic clock, for example). At some point, though, the accelerative forces cancel out the cooling forces, and mass destruction begins.
A photon doesn't experience time because it has no mass to accelerate.
It does, however, experience space and collects information along the way that is imparted into the detector at journeys end.
Time within the Space frame is just information. No atoms actually exist outside of the present.
Great comment, I think it helped me understand, but a question if you do get this, does that then mean that light has infinite speed, but because of the fact that we can only measure light because of time, that time itself it the limiting factor in it's measurement?
Gonna break my brain, so for example say you have a vision of 100km, at one end you see 100km, straight infront of you, but if you move 150km in, you will now see 100km to your left and to your right, this is of course assuming a 2d universe or whatever, by moving in we are changing out measurement position, so we can see more, but the rule has not changed.
@nineonine9082 light has a propagation rate. It's speed is based on the permittivity of space. Permittivity is electrical energy. To have infinite speed, you would need infinite energy. You are at the center of your visible universe. Since the permittivity of space is essentially uniform, excluding black holes and such, your visible universe is a uniform circle around you. Stationary objects drop in and out of your circle as you move about in space.
I dont get really get this.. on what basis do you say that the photon will travel 300000km/s away from you even when you are travelling at 299000km/s.. pls bare with me here ive just been introduced to all this
@@xaviermax4788 the speed of light is ruled by the permittivity of the space in which it travels. Permittivity is electrical energy. Speed is how fast a wave can be propagated. The length of the wave determines the distance the photon has to travel in order to propagate a new photon. When you move away from the propagating source, the photon has a longer distance to travel. When you move towards the source, the photon has less distance.
Time-dilation is the effect of your speed by Y and the photons speed being X with respect to the motion of travel.
If one person is standing still, throwing balls at a target moving away, the ball takes longer to reach its target. For some unknown reason, maybe it's because the target is a counter, this fundamental aspect of physics has become known as time-dilation.
If you move a block further away from work, is that called time-dilation because it takes no longer to get to work. How about moving away from a broadcast radio station?
When dealing with the speed of light, you are dealing with the time-dilation of information. Your actual time is still progressing at 1 second per second.
Since the laws of physics are equally valid in all frames of reference, acceleration in space (change in spatial coordinates) also causes and acceleration in time event. How much acceleration is determined by the mitigating factors. The cesium-133 atom of the atomic clock is chilled to absolute zero to prevent it from being accelerated in time when a force is applied. This makes the clock an instrument for measuring acceleration in the Space frame. Acceleration in the Time frame will vary based on the force being applied to that frame of reference and how the mass of that frame reacts.
The denser the mass is, the more force is required to accelerate it in time, time being converted back to and from radiant energy. E=mc. Atomic energy is converted to radiant with acceleration.
F=ma primarily deals with acceleration in space. E=mc, acceleration in time -> change in the structure of the mass.
Mass can be radiant energy (electromagnetic waves), Atomic energy (animal, mineral, vegetable) or information (body of knowledge knowledge).
Electromagnetic waves are force carriers. What do they carry? Information. F=ma. Force equals Acceleration The fundamental law of the universe.
If you understand that, then you understand the universe.
Anyone else not here from school and just interested in spacetime???

Lol I understood the video was about Einstein and nothing more

Hahaha!!!
I had struggled with this for years, despite being a physicist and engineer.
The problem is that the thought experiments on this topic are fallible in many ways, if taken too literally.
[For example, what if the clock tower was on a train moving away at the speed of light from a stationary observer, or if the observer was on a train that started on an approach to the clock tower, then continued past at the speed of light?]
For me it took a completely different perspective to understand it, building it up in stages:
1) If every particle in the universe was static with respect to each other, there would be no interactions, and it would seem time had stood still, because nothing is changing. For time to become apparent, particles need to move and interact with each other, energy has to flow.
2) The speed of light is a universal constant. Do not consider light as an object, like a ball moving through space. It is a limit on how fast events in one region of space can cause events in other regions of space ("causality").
3) If you were travelling at the speed of light, the atoms and particles that make up your body would not be able to move in the direction of travel (relative to the centre of your body), since they would have to travel faster than the speed of light (violating causality...the outermost molecules of your body would arrive at your destination slightly before you should be able to arrive!). Hence all the particles in your body would actually be static relative to each other, and therefore you wouldn't be ageing. Furthermore, you wouldn't be able to have a conscious appreciation that your ageing had ceased, since even "thinking" would require movement and interaction between the particles in your brain.
4) Since any object's perception of time is relative to the "relative interactions" of the matter it is made from, it cannot perceive the difference between a tick (at zero speed) or a tick (at near the speed of light....a "tick" is a "tick" according to the object observing or recording its own time.
Due to the principles of a universal speed of light and causality, moving through space will necessarily slow the mechanism of the moving clock, and by an equal amount, the mechanism by which the moving observer is able to observe the clock. A clock moving through space actually does tick slower than a clock not moving through space.
[A profound thought regarding point (2): If the speed of light is measured by causality, and causality infers change, and change infers the passing of time....if time didn't exist, would there be a speed of light? Would there be light?]
In the context of this perspective I can go back to the original thought experiments and understand which aspects of them are useful in deriving the maths.
These are all my own thoughts. I don't know if any professor of physics would validate them. But where the original thought experiments left me feeling dissatisfied, this new perspective helped me.
I am going to pretend i understood that
@@ayesha1929 lol.. I can relate very much to your pain..😅
.
Ur smart i like you
My question to someone who understands time dilation and speed of light is...photons move at a constant speed, no matter how fast the observer is traveling. Light still travels at 186,000 miles per second. So what if I'm moving at the speed of light, and I shoot a photon from a flashlight. Are me and the photon traveling at the same speed side by side. Or does the photon shoot off at the speed of light? Well it can't because then it would be going twice the speed of light to someone stationary. So I assume if I emit a photon while I'm traveling at light speed, then the photon would look stationary to me

Let's just acknowledge how all of his theories were "imagined" before he proved them
Really fascinating. One thing I personally find interesting is the discussion of time relativity in the Quran, which was revealed about 1400 years ago. It discusses, for example, how time is experienced differently in the different ‘skies’ or ‘dimensions’ of the universe. It’s mentioned that there are 7 such ‘skies’ or ‘dimensions’ (in fact - we’re told the observable stars belong to only the first sky/dimension). For example, one verse translates roughly to: “He arranges [each] matter from the heaven to the earth; then it will ascend to Him in a Day, the extent of which is a thousand years of those which you count.” [32:5] I find it very interesting, especially given it was revealed about 1400 years ago :) If you’re interested in learning more don’t hesitate to ask.

THEORY OF RELATIVITY VERY EASILY EXPLAINED
Light Travels at a specific speed. When he watched the clock tower, the light that entered his eyes allowed him to watch the clock so if he travelled at the same speed of light, the light would never catch up to him so he would see the same position in the clock.

Even if special relativity did not exist this would be true. This is just the neurological effect. Special relativity is different.
You misunderstand
A long long time ago, I remember being told in the 5th grade of the 3 dimensions and then hearing my teacher say "some people even say there is a 4th dimension". On the way home I told my dad, "If the first dimension is height. Then length, then width....then the 4th dimension has to be when that object exsisted.". So I like to tell myself I theorized space-time as a child. (I mean, not really but close enough lol)
That is nice. when he traveled away from the clock tower at the speed of light the clock stopped. Then you must realize that is cus of the light waves emitted from the clock would not reach him cus he is also traveling at the same speed. so he will only see a snapshot. then how he can tell that flow of his time slowed down by that experiment according to this video?
@@ceylongamersleague9733 Its all a matter of different frames (of reference), to someone inside a bus, he isn't moving so he he sees himself at x=0 (the orgin) always. So to him time is/appears slowed down but to the res of the world, time passes at its normal rate. Also he observes things outside of his stationary frame, ie not stationary wrt to him/his fram, to be of shorter lengths than the world around him, starionary to everyone else and where he seems to be moving at relativistic speeds x approaching c the universal speed limit, 299 792 458m/s
I feel like giving you a hug. Not many children have this authentic zest for science. Children are so special they should be exposed to more science in their lives, they’re little geniuses and they don’t even know it.
Because it was theorized that speed of light always remains constant, even in a relative frame. If you travelled at say 50% the speed of light and cast a beam in front of you, light would still appear to go at 3×10⁸ ms in front of you. This is what was contradicting Newton's laws of motion.
If you were to travel towards an observer/object, the time dilation effect would be the same as if you were moving away from the observer. In other words, the time dilation effect is symmetrical, and it does not matter whether you are moving towards or away from the observer. The only thing that matters is the relative velocity and gravitational potential between the two objects.
For example, if you were on a rocket ship traveling towards an observer at a high speed, the time dilation effect would be the same as if you were on a rocket ship moving away from the observer at the same speed. In both cases, time would appear to pass more slowly for you compared to the observer, due to the difference in relative velocity and gravitational potential.

@@keimoji I get the speed relativity but how does that affect aging or time? Like if there's 2 people, one on Earth or in a certain point in space. Person 2 wants to travel to another point, and it is exactly 1 light year away from person 1. So it takes 1 year to get there at the speed of light. Then person 2 goes back to person 1, so another light year. That's 2 years that should have passed, for both. Yes, person 2 will see that everything is slower, but that's only relative. Ageing and metabolism wouldn't change, so I don't get how 2 would have aged slower.
@@Shvetsariothis literally this is the only thing stopping me from understanding this concept
@@Shvetsario This isn't a good video but I think the answer to what you're asking is that 2 years won't have passed for both people. When person 1 waits 1 year for person 2 to arrive, person 2 doesn't experience 1 year. Because they are travelling at the speed of light, they would only experience a fraction of a year (as time is moving slower for them). So relative to person 1 they travel the same distance in much less time.
Another way to think about it is; A Light Year is the distance it takes light to travel in one year from the relative perspective of the stationary observer.

Time dilation has no significance for time travel in physical plane. It actually indicates the depth of space-time while observation made on speed of light is a projection at the surface. And time dilation said to be due to gravitation is also not true, it indicates the difference in levels of crests and troughs along the surface of space-time.

Amazing stuff; the moment I learnt the speed of light is not about light, but causality, I started to understand causality probably dictates all the experience of space and time we have; and it makes sense (causality is so fundamental; like something needs to actually happen before you see it happens, there’s no way around it); I would even think causality would REQUIRE the universe to exist and exist in the exact way we see; hope some great minds can resolve this
can you explain it briefly?
Actually one big flaw about this video is the sentence "The faster you move through space the slower you move through time" and this really confuses most people here cause they get a wrong idea of the concept. Your own time still runs the same for yourself. Only if you compare your own watch to the clock tower you can see the difference and realize that time in your own referential passed slower than the time in the other referential, thus the word "Relativity" cause it's all relative to where you are and how fast you are.
So the sentence is not really wrong but it visualizes a wrong idea.
the senseful comment i seen so far
Referential?
How can time slow down just by u going fast it remains the same it’s just that u cover more distance
@@speedracer7684 well, that's what the video is about.
And who is to say I am moving faster than the clock tower?? The clocktower is moving away from me just as fast as I am moving away from it. Relativity right? I'm only moving away from the clocktower if the frame of reference is the earth surface, but earth and the solar system and the galaxy are moving too. So what if I am compensating some of that movement by moving away from the clocktower? I would be moving slower than the clocktower, so now the clocktower's time should move slower. Who is to say what object moves with what absolute speed when all speed is relative? The explanation is illogical and is not thought through to the end.

Still doesn't explain why half an hour break is faster than half an hour work!
Haha.
Working requires movement, therefore time feels slow for the most part. But taking a break doesn't require you to move most of the times, therefore time feels quick.
yes it doesn't because this is bullshit after all. Time is a perception. What's slowing down or going faster is not time but how you perceive it, the more you are aware the slower it goes, the less you are aware the faster it goes. Time is constant, no past or future exist, there is only now, we are the ones conceptualizing those things in our head. One thing i don't like about this is that they assume that if you move at the speed of light you are fully conscious of all the information you pass through, but in reality you won't see shit.
It’s relative
@@deanasaurs It's even slower when my relatives are in town -_-'
The animation is so good . Good work man 💓
The one part of this that will never click in my brain is the concept of aging differently based on what speed you are travelling, I've never seen that part of the law explained in a way that makes any logical sense at all.. I understand relativity, I understand that the faster you travel away from something (say, Earth for example) then the slower in time it appears to move, up until you travel at light speed where everything you observe back on earth shall appear to stop in time - I get that no problem. What I don't understand is that surely the moment you travel back towards earth at the speed of light, then wouldn't you just observe everything on earth moving much faster now, therefore technically "undoing" the slowed/stopped time that you previously observed..? How is time dilation anything more than a mere observation, how can it possibly be an absolute change in time if you end up travelling back to where you began your journey? I want to make sense of this and have tried for years but I've never seen or heard an explanation that does it justice.
same
commenting here so I get a notification in case someone posts an answer
I think it is because you somehow get closer the speed of an unit of time thus,time goes by soo slowly , and space is becoming meaningles compared to people on earth,while everything about space is still same on earth and going on its own pace .For the person on earth to perceive things about space ,there needs to pass more units of time.I hope i could explain what i understood.:)
Maybe because light experiences no time, therefore if you are a massless particle going through the universe at the speed of light, you would have to be light. It’s un achievable to weigh and travel that fast otherwise light would be able to go faster then it already does if that makes sense. I’m no expert
Yes, that makes me frustrated also!

"The faster you move in space, the slower you move in time."
That's not what relativity states. Relativity states that - as one accelerates, time changes. Velocity has nothing to do with it.
This exaggerates it its more of the faster you move the more time you save
the thing is motion is relative, so the statement should be the faster you move w.r.t an object the slower time is for you w.r.t that object
That's one way to look like you've aged faster through the future

For those who didn’t understand shit
The faster something moves, the slower time moves, because you’re moving fast enough that you don’t perceive time as everyone else perceives it
the slower it seems to move. the clock and devices we use to measure time are not time themselves. the clock has no effect of the actual passage of things from potential to actual. if you move the clock back 1 hr, nothing happens to the universe, time is still constant. time just is
This is why fat people die earlier. Joggers spend time running so time seems to slow down for them compared to the fat slob sitting in his sofa.
And all this time we thought it was the fat that was dangerous.
@@staneze3972 So what you mean is time doesnt actually freeze or slow if you move at the speed of light in space, time is constant and its moving at its normal speed, so its a perception thing, when you move at the speed of light new light doesnt enter your eyes for your brain to show the present time on the clock so youre basically seeing the clock freeze, but for someone thats near the clock the clock isnt frozen? But Im curious to know what will happen if the person moving at the speed of light suddenly haults? Will he be living in the past and everyone else on earth in the future?
@@lucifer-mp8fc no he won’t be living in the past or the future . You said it beautifully , light wasn’t reaching his eye because he was moving at the same speed as light . He only becomes aware of what was unable to reach his eye. He’s no different than someone that was asleep and wakes to see all that has changed . See, when people say arrive at the past or future what they also miss is this . Time, space and matter are 3 things that MUST happen at the same
Instant. If one lacks then it makes no sense , if no space, where will you put the matter and if no time , when did we become aware of it ? Saying someone arrived at the past, he or she must see what they’ve experienced before and for arriving at the future , there is no such thing as “the future.” Our current choices shape whatever happens later in life.

Same here,🤔 I honestly think there's something missing in this theory. There's something "odd" about it and I'm trying to understand how the math actually came about.
@@callmestern It doesn't make sense at all, trust your gut. I suggest you to watch Bill Gaede(Physicist Professor of Rational Science), he touches on the definition of "exist" and separates the fine line between OBJECTS and CONCEPTS. Time is a concept, it does NOT exist, Time = comparison of two motions (Seconds, Minutes, Hour is a tick on your watch, the movement of one hand to the other)(Day is full spin of earth) (Year Is orbit around the sun) Concepts are just relations between 2 or more objects. For something to exist it must be an OBJECT, that which has shape and location. Time does not have shape and location, and math physicists treat a clock as the embodiment of time which is totally irrational. If we used an hourglass, which is a clock that works specifically through gravity, it would've showed that its the opposite of what Einstein said he predicted. Its not that the clock is faster out there in space, its quite the opposite it runs slower. And if you take that same clock, and you take it to sea level that clock will run faster because it's closer to gravity and the grains are gonna come out of the little glass container faster. So our clock proves general relativity wrong because it has the opposite effect of what they "predict" as its known. They call it a prediction, well here's a prediction, I'll say that my clock runs faster when its at sea level than out there in the middle of space. In fact if you take it further out not a single grain will fall and according to the lunatics of relativity, they would say that time had stopped because they decide everything by measurement. And now if not a single grain falls because there is no gravity out there they say well time has stopped. That's what they would conclude, that's their rationale, that's the way a mathematician thinks. He says oh it goes slower slower slower, and when it goes out there where there is no gravity they say oh it stopped altogether so now time is no longer flowing or it stopped altogether. 🤦

Find the point where science and art are one. True art is said to stop the mind in it's tracks. The mind bows to that which is beyond it's capabilities. Einstein is said to have made his greatest discoveries when his mind was still. A state of no mind was his clearest. The ideas just came to him if I read correctly.

@@oberstabsfeldwebeldoge4115 no sir ur wrong
Not actually becuase he does not run forever
at 1:13 when Einstein is watching the clock by moving with a speed of light, the time at the clock is actually changing there, but the old light ray is still moving into space taking long way if he travels with speed of light. so the time in the clock tower and the time (in einstein's watch) would be same at any give movement.
But if any one calls by phone and say the time, the phone signal would take the time which light takes. so, even then he would not be conveying the exact time. but if (just imagine) one can make phone call which gives information instataneously with infinite speed (which is not practically possible), then the exact time can be conveyed to einstein by phone. then there will be no dilaltion. the time dilation is felt because of speed of light.
also at 4:00, the man on the train going at the speed of light, it is told that the time is slowed down for him. if there is a blind man on train, does it mean that there is no lightning strike for him? it's not for Einstein or for man on the train, the happened event is at exactly same time. it's not that time is slowed down for him, light ray is quick on him.
at 7:12, for the man on the hill, the photon clock (on the man falling from a height) will actually look moving slightly fast to complete the strike in 1 second. it won't slow down for any one. the example is like watching the Television and moving to the corner and expect to stay away from the gaze of the anchor (which is not possible).
time dilation concept is not convincing. I feel it's light dilation..!
The theory becomes less understandable when you watch more videos on youtube and authors explaining their own understanding like it's written on the rock.

Exactly, it makes no sense, you can't just decide that time must slow down.. All you have to do is think logically for a moment, two people in the universe are always going to age at the same rate. It is not possible for one to age faster or slower based on gravity....

The true phenomenon behind the GPS is that matter is affected by speed with respect to gravity; not time. This is common sense.

Thank you for this video, lots of video's do not give mention to the fact that Einstein's final theory does see: the speed of light as a constant.
It really is important to integrate that with the general theory of relativity, all things actually do have a speed with respect to light. thats how its possible to know your speed with a light clock, and not a mechanical one.
How is each relative speed translated with respect to the light constant? Is there a different equation?
@@elijahgavin6706 your speed can actually be measured as a fraction of the speed of light, and that is also going to control time dilation.

If you're a sprinter or know about sprinting, this is pretty easy to understand. The faster you move, the shorter amount of time you use. Also, the reason the earth doesn't roll toward or away from the sun isn't because of fabric being pulled. It's because the earth is rotating/spinning & not rolling. Using their example of a marble, if you spin a marble it it will stay where it is or move in a circle. If you roll it it'll roll. Since the earth is rotating/spinning, it can't roll at the same time. The sun bending frabric & forcing the earth to move in a circle or oval isn't necessary if the earth is rotating.
"Time Dilation" is that time between taking the eye drops and when your sight returns.

Vallatha kadha kand vannavarundo ivide
At the very beginning of this video, the one thing that is missing, is that Einstein wouldn't have had the time to imagine the hands on the clock seeming to slow down. The fact the he imagined traveling at the speed of light, but was still in real time, allowed him to imagine the hands on the clock moving slower, when in actuality, he would have already arrived at his destination were he traveling at the speed of light. Now yes, the hands on the clock do appear to move slower, but let's say Einstein was having a conversation with someone. He would barely be able to get the words out before arriving at his destination. The hands on the clock would barely get a chance to move. Einstein would be traveling at the speed of light, but his bodily functions would not increase in speed, his heart rate would not increase in speed. His digestive system wouldn't work faster. The only thing that would change would be the speed at which his body was traveling from one location to the other. The functions in his body would not speed up, nor would his speech, or his respiration. If Einstein kept on traveling at the speed of light, without stopping at his destination, the hands on the clock would seem to move slower if he could still observe them from far away. His body would be changing it's location faster, but everything else associated with his body and it's functions would not. If he got up and walked in the direction the trolley was going, towards what would be considered the front of the trolley, the speed at which he is changing locations would increase, but the speed of his thoughts, the rate at which he swallows water, and if he was wearing a watch, the hands on the watch he would not increase in speed. So I don't understand why time would speed up or slow down. It may seem that way because Einstein had the time to sit there and imagine the hands seeming to move slower, but in actuality, the hands would barely get a chance to move at all because Einstein would have already arrived at his location. So the speed of time never changes. The length of time that is measured can be shorter or longer, but the speed of time does not change. If you are standing between two bolts of lightening, the light emanating from the bolts would reach you at the same time. If you were passing by in a train, the light from the bolt closest to you would arrive at your eyes faster, but the light would still travel at the same speed. It wouldn't speed up or slow down based on the speed the train was traveling. Not would time. And the only thing that changes the speed of the train in relationship to the train station would be the train's engine. In the film interstellar, I really don't understand how the people in the ship, traveling at the speed of light, would = their kids growing up faster. And being on the planet with intense gravity, I do not see why that would change time for the people on the planet vs the guy not on the planet. The people leaving the ship to visit the planet would come back whenever they decide to come back, but I don't see how increasing the gravitational pull would change time for them vs the time for the man on the ship . If anything, they would arrive at the planet faster, but would have difficulties escaping the gravitational pull of the planet when trying to leave. Is that what changes time? The fact that it takes longer to escape the gravitational pull? Because I feel like if the guy in the ship could have a phone conversation with the guy on the planet, one guy wouldn't be talking slower than the other guy just because of the gravitational pull of the planet. I guess this is what I don't understand about the theory of relativity. Or maybe I do understand it but I'm thinking it's something that it obviously isn't. Anyone want to explain?
Dude I was already not satisfied with this video, you confused me more by asking a Genius Question ' person speaking in a phone from the planet.....' that was a great thought. But what I think is we are having difficulty understanding Einstein's concept and this whole video has not explained it correctly. We should search for some other explanation to better understand.
That was one of my concerns from interstellar, your feeling of the second does not change, why would time change some where else? A second is a second, it's just a measurement tool, why would it expand and contract in terms of the one experienceing it? That's what I don't understand or comprehend. As you said my friend the ship might need more power because of gravity, and if it's slower it doesn't make it quickly
@@raguravi1659 there are other better explanations, I came across some of them and I have a better understanding of the theory of relativity. They have to explain it correctly. Gravity is equivalent to speed because speed creates G-Force. So I understand that better. Light always travels at the same speed no matter where it is, what it's doing. If you're in a car traveling at lightspeed and you turn the headlights on, the headlights still travel at light speed. Therefore Einstein hypothesized that light is the eternal constant that all other units of measurement bow down to. Speed, time, weight and mass all change, but light does not. It's something to do with that. Equally strange seems to be the ability of larger denser objects being able to warp reality or space-time.
@@jackjones5484 I watched a few other videos and I understand it better now. Gravity and speed are the same thing in the case that G-Force is involved in speed. Time and all the other units of measurement change as you approach the speed of light or intense gravity, because light always travels at the same speed no matter where it is.
@@TMundohere So would you explain the kids getting older part in Interstellar?
The only thing I learned was why I don’t know the theory of relativity.
I really like the way you explained this video regarding the dilation of time. I don’t know, maybe it’s your calm demeanor that made it all the more interesting. Be that as it may, please don’t stop making these videos 👍🏼
