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!

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.

@@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.
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

@@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.

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.
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😢

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.

And Einstein was their leader.
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..!
Is it just me, or does everyone else feel like suffering from a mental incapacity when listening to such subjects?!

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

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?

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.

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.

Subject: Elimination of leap years, days, and seconds under base-375 numerical system :) Would a year with 4140 days eliminate leap years, leap seconds and leap days in a base-375 system? If so what would it look like? If not how would the leap days apply? ChatGPT A year with 4,140 days in a base-375 calendar system would indeed eliminate the need for leap years, leap seconds, and leap days, as it's a multiple of 375 (375 x 11 = 4,125). This makes the calendar very regular, with each year consisting of 11 months of 375 "days" each. In this scenario, there would be no need for leap years or leap seconds because the calendar's year length is a multiple of the base unit (375) and doesn't deviate from it. So, in your base-375 calendar system with 4,140-day years: Each regular year consists of 4,140 "days." There are no leap years, leap seconds, or leap days necessary because the year length is an integral multiple of the base unit. This approach would create a calendar system that eliminates the complexities of leap years, leap seconds, and leap days, making it very regular and easy to work with. It would be a simple and consistent way to measure time in a base-375 system.

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.

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.

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.

@@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. 🤦
