Time Dilation - Einstein's Theory Of Relativity Explained!

- Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time dilation. But what is time dilation? Time dilation and space time are interrelated. Einstein made one of the most important contributions to physics and had the concept of space time explained. A simple explanation of space time is that it is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. But it is very important to understand that the general theory of relativity and the special theory of relativity are different. In this short animated video, we give a simple explanation of time dilation and Einstein’s theory of relativity and also explain how time slows down in a moving vehicle!

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.
now i know why i am not smart at school way back then, even now i still dun understand after watching this video 😂
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.
Time dilatation is when the alarm rings 7am, u wake up and blink your eyes for half second, and its already 730am

Thanks, gradually after watching these extremely useful videos a few times, I am beginning to understand these concepts of time dilation and Einstein's theory of relativity.
Why I still don’t understand 😢
@@HappyKawinnnn I never said I understood completely, I only said I am beginning to understand. So we are in the same boat.
@@jesusbermudez6775 ahhh thanks bro. appreciated! 😂
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
Einstein travelled home by a tram
That's all i understood

Lol I understood the video was about Einstein and nothing more

God: you're fast af bois, you both have no idea... how fast you really are
Heisenberg: I don't know my current speed but i know currently where I am
"If you were behind me, I was going exactly 0 mph"
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 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 😂
The animation is so good . Good work man 💓
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.
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.

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.

That’s the kicker. Once you realize that space and time are things, a lot changes.
@@josephsharp9939 yes you lose your connection to reality and you'll believe anything at that point, except the Bible.
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.
Thanks for explaining.I was also thinking about time dilation before I watched this video
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?

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.

7:20 Very nice animation! It shows nicely why the speed needs more time to bounce between the two borders despite moving at the same speed at for the other two observers - because it need a longer way. But I wish this animation would also explain why time runs also slower for the man on the hill and the man in the UFO from the perspective of the falling man. Because if we switch to the perspective of the falling / moving man, then from his perspective his own light bounce runs at a normal time, but if he looks at the man on the hill or the man in the UFO, then they also seem to movie slower (or their light bounce devices in this case). I always though that from the perspective of someone who is moving faster, everything from his point of view and "outside" of his sphere (like the two other people) would actually move faster and not slower too, since this would be the logical consequence. But apperently I'm wrong as I learned. I still try to understand why. It also kinda contradicts what is sometimes said by other sources or movies, like Interstellar. When they were on this water planet, from their point of view their own time ran at a normal speed but the rest of the universe (including Earth and humans) ran faster through time. But from the point of view of the rest of the universe, everything ran slower on the planet. Everybody says something contradicting.
What's correct now? If I move in my spaceship close to the speed of light through the space and I watch outside the window of my spaceship to planet Earth, would I see everybody else moving like in a timelapse very fast or would they move slower like in a slowmotion from my point of view?
In ship's frame, earthlings would be moving slower.

Me - but speed is relative.
Velocity not speed. Speed is a scalar quantity and does not have a direction.

@@AndT101 speed is also relative...it depends on which frame of reference you are concerned about...i m stationery wrt my surroundings but i m moving wrt to the sun and other planets in the solar system :/

This is quite a good video on this topic. So far I have understood that there is a contradiction in Newton's laws of motions that state that the speed of objects is relative and that the speed of light is an exception to this because the speed of light is constant regardless of where are observing it from. So Einstein came up with a solution to this. I will see this video again a few more times for me to finally understand this.
Einstein’s Relativity Theory briefly explained. In nature there’s no instantaneous interactions, therefore must have exist some velocity limit, which is the speed of light, which is invariant to the the different inertial frames of reference, that’s the key, hence the dilatation of time and contraction of space observed by those observers in those different inertial frames of reference one in relation to the other using the speed of light as a measurement’s instrument.

my head is same age as my feet cos I'm always lying down
If you are laying down on your back then your dick is older than your butt 😂
i can’t 😂
Do you all buy this nonsense??
guli yano the theory of relativity? Yeah its a pretty big deal
@@dontsubscribeme9547 just because you don't have the mental capacity to understand it doesn't make the complex theory nonsense
everybody gangster till people start moving at the speed of light
Who else finds this completely fascinating? I have never learned about time dilation in school. It makes it so interesting.
Special Relativity/Time-dilation isn't taught in school because it's science fiction.
Yes it’s amazing especially after watching interstellar
W vid really helped me out during science class 😅

Big typo in the subtitles at 2:37, it's speed of light not speed of life. Thank you for correcting it :)
Nerd
Brilliant explanation
My mind was blown multiple times. I need to spend more of my free time contemplating the truths of the universe.
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.
The thought experiment you mention in the beginning could also be explained like this - since he's moving at the speed of light, the light that repelled from the clock to his eyes is traveling at the same speed as he is
Thank you for this. I was already confused.
Why? Why does the clock appear to freeze? You answered that perfectly.
Silly of the video to assume that would be understood with no prior education on physics.
Majesty:: Time. ??? Old watches time. 1800 Old watches 30minets =1900 New watches 60Minets .. if you have old watches time. Let it show you. Old watches work exactly 30minets = 60 minets new watches .Are we Ocupaited from Aliens 👽??? And we didn’t know!!😮 😂 !!
This is the most interesting theory ever ❤️
"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
@@theboiyoulove5124 bro wrt is with respect to. Why r u writing to again lol
Forget discovering new things, my goal in life is to understand the physics already discovered
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. 🤦
That last line is gonna mess with me for a while
I understood everything yet it still seems unbelievable
Imagine if someone distracted Einstein while pondering the theory of relativity

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!
Thanks, this video gave me a different perspective of The effect of planet’s mass on aging process.
Glad it was helpful!
Neat. Thanks!
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
