The fact that Einstein came up with this theory in his head without technology is absolutely insane!
You ignored one thing dear that we are the super technology i.e humans a complex one why complex ask yourself, just see around how we have done & what we have done so far either good or bad. It's just we have to use ourselves wisely in & out keeping everything in balance that's it. Means we have to use our brains wisely. Remember balance is the key to life & beyond!
Thankyou 'God bless!🤍🙏
I get what u mean but pieppe often renove certain factors from the yhought. For eg. They think einstein came with this idea from scratch. And he found gravity n all. He took 2 ideas and mixed them together. Still a super genius but not as genius as people think still genius tho but not as BUT STILL A GENIUS
@@Lifeislikemypfp who's a super genius in your opinion
he ate alien juice to be able to create this theory
@@yousefabdelmonem3788 He just said Einstein
This is honestly the most well explained video on special relativity this should be shown in schools
Absolutely. I played like 10 videos with tons of views on CZcams but none explained it really well like this one, graphics and examples are perfect.
Amen.
It’s the worst explanation ever. It’s overly simplistic and not reflective of reality in its attempt to exploit explain it
Its plagiarism from Brian Greene and its not the best explanation of SR that's for sure. A 3D geometric image of spacetime is the most intuitive interpretation of our universe. This tutorial is good but does not explain what time is, so is insufficient and unreliable, and certainly NOT worthy of teaching reality to others. This video should be removed from the internet for misleading its viewers into believing a false reality.
@@Machistmo - Yeah, I just don't see how this explanation is accurate. For instance, with the two people on the train signing the documents when they see the light go on, what difference does it make if you are standing on the platform watching the train go by, or if you are on the train? This video states that the people watching from the platform will see the one person signing before the other one. WHY??? They stressed that the speed of light is constant. We also know that each person on the train is the same distance from the bulb. So, when the light bulb lights up, BOTH people on the train will see the light at the same time, and thus begin signing at the same time.
And with the clock which is a light ball bouncing up and down, I can see where a stationary observer watching the clock race by them will see the path of the light ball being in a diagonal path, but so what? Let's say the clock "ticks" every time the light ball hits the top "plate". If the speed of light is constant, then the amount of time for the light ball to complete one cycle (ie: go down then back up) will be the same regardless of how fast the clock is moving. So how exactly is it showing a slowing down of time if the time it takes to complete a cycle never changes?
Maybe I'm missing something here, but I just don't get it.
I've watched so many videos on special relativity, and I think this is the first video where I can actually sort of understand it. Thank you. Well done.
Time-dialation is an illusion of charge. The specific charge changes with speed and changes the clocks. Also, the density of the medium changes the speed of clocks. You can find a better explanation from dialect. Everything continues from moment to moment even if some of them don't decay quickly on the nature of their waves.
This was by far the video that explained time dilation in the easiest understandable way possible. Now I feel like my brain is finally starting to grasp the concept. Thanks, guys!
So that is the reason at the end of interstellar movie, the daughter had become very old when compared to father. Time slows down when an object is in motion. Great explanation!
I think technically in Interstellar, the time dilation is caused by the extremely large gravitational forces of the black hole, which is dealt with by general not special relativity. But the practical effect is the same, high speed/high gravity = the slower time ticks.
It was the gravity. Not the speed. In his case.
No time does not slow down when in motion. Time only slows down at velocities nearing and exceeding the speed of light,
Time is only slowed in reality bye gravitational mass.
The movie interstellar was an attack on science bye the christian evangelic republican party lead bye the most ignorant racist arsehole on the planet mathew macogney.
Nothing on in that movie was based on science.
It was like watching a creationist video on youtube staring ken ham, kent hovind and ray comfort.
No it is not, this is special relativity where as in interstellar it is general relativity causing the time dilation.
People have already told u it’s due to gravity so i’ll skip past that. Instead, I’ll try to explain it the best I can through a comment. A good way to differentiate between special and general relativity is that special relativity is in fact a special case in physics. Specifically when there is no acceleration. General relativity, however, does consider nonzero acceleration. In fact, in general relativity gravity can be thought of as purely an acceleration. Exactly the same type of acceleration that you feel in the car or on a train! Now this is where it may get a little confusing: in special relativity, higher velocity causes greater time dilation; in general relativity, a lower potential energy causes greater time dilation (specifically gravitational potential energy). You can think of a person on top of a building for this. That person would have a greater potential energy than someone on the ground and would therefore be farther away from the center of the earth. Because of this, gravity would be a little weaker for the person on the building than it would for the one on the ground. Therefore, the person on the building would perceive the person on the ground to be moving slower than normal. This is a very basic and minimal intro into GR. To really learn it you’ll also need to learn a lot of tensor analysis. Really cool subject if you ever get the chance to study it.
Its such a shame that this video has only 5k views while the information in it is priceless. Never understood these concepts in school. Our schools need to adapts to something like this so that the kids can get their concepts clear.
I thought you were against religion being taught in schools. If your religion is going to be allowed, then so should mine and all the others.
Do you really think that Einstein’s Relativity describes this universe. That you will be granted eternal life at the speed of light.
Keep religion out of public schools.
@@stewiesaidthatWhat religion are you talking about? We are talking about REALITY here. Not fairy tales, magic, or an abusive supernatural being that says he kills people’s family members because he loves them. Stop comparing education to your primitive ancient books.
@TheGreatKhan The Religion of Relativity. Or aren't you aware that it promises you eternal life?
I dont know what rock you are living under, but Einstein created a fair tale Spacetime universe to peddle his religion.
Example,
Relativity universe - traveling at the speed of light, one does not age. One does not experience a moment of time.
Real universe - an astronaut's heart rate is ACCELERATED on the way to the speed of light while the onbosrd clock is decelerating.
Relativity universe - mass increases as acceleration I'm space increases.
Real universe - mass decreases as evidenced by hot water (accelerated) having less mass than cold water. That solar sails are disintegrating into space on the way to c.
The reality is that nothing can exist long enough to make to make it to c.
Einstein’s Spacetime universe is a fantasy universe. Created to peddle his relativity theories when they weren't working in the real universe. Call it pseudo-science, religion, and BS. It's all the same. The fact that you are here, worshipping Einstein, proves that it's religion.
@@stewiesaidthatTime dilation is not only real but essential to our everyday life. GPS satellites measure the distance between themselves and Earth based on how much time dilation there is due to the difference in gravity between Earth’s surface and space.
@captainzekrom57 that's not time-dilation. That's information dilation. Clocks measure one's motion in space. A car slowing down going up a hill is not time-dilation as you can apply more force. GPS satellites do the same thing. Change the amount of force to compensate for the different environment they are operating in
I suggest you do your own research and quit parroting Church of Relativity dogma.
It's still incredible to me that our brains can slow the perception of time in extreme moments and altered mental states. Had some incredible slow mo events during combat. Really changes how you view your mind and it's impact on your reality.
How
I watched one and continued to watch four more. Wonderful videos you’ve made. Outstanding explanation with amazing animation. Makes everything so easy to understand. Plus the speaking style is really appreciable. It’s simple, generates interest and doesn’t bore people out. Thank you for this.
I found this channel yesterday and been binge watching all of the videos. This channel would surely be on the top
I always wondered about theory of relativity. Due to complex videos, without good animations it was difficult to understand the topic.Your examples made it crystal clear.
Now my concept is clear and I can explain it to anybody with ease.
Thanks Klonusk.
This video is putting all the fragments I've picked up from other videos over the past couple days and putting everything together with a bow on it. Thank you.
This is by far the best, most well-explained video around this topic. Although there are many other really cool videos about it, yours is incredibly fun and intriguing. Keep it up!!
This video simply explains the concept for whoever struggles to understand after watching tonnes of other videos on relativity. Appreciate it!!
Wow man, you really nailed the explaining! I always struggle to explain the train part i.e. if a train is moving with the speed of light it and a person in the train say starts running at 5km/hr he will still be running with the speed of light. I find it hard to explain this as I’ve studied physics quite extensively while people I try explaining it to have not. But you my friend totally nailed it. I believe either you or the script writer are definitely physics pro! Kudos.
I still didn't get it. Speed of light is constant for static observer...why static observer will not plus 5 in that?
I know speed is light is the limit, but don't know why?
If you keep making quality videos like this, your channel is gonna be huge in the future. I wish you more success.
Best explanation and graphic representations I have ever come across here, thank you and great job
You made me understand 90 percentage of it . Easily the best explanation of time dilation !!Thank you!!.
I’ve seen countless of videos trying to explain relativity theory and time dilation. This video is BY FAR the best at explaining it! I’ve come to understand it before, but after watching this video I think I understand it well enough to be able to explain it to others! Big thanks for this!
Alright then, how would time dilation work with a mechanical clock instead of a light clock?
@@kylelochlann5053it wouldn’t. All these time effects ARE technically optical illusions.
@@joshuadehler5039 No, the optics are totally different and include the time dilation within the analysis, e.g. Terrell-Penrose effect, relativistic aberration, etc, etc, etc.
Time dilation is a different phenomenon; the ratio of observer world-line length to the traveler world-line length in the coordinates of the observer.
WOOOOOOOOOW, A piece of beauty of how well-explained, well-viewed, and talented way of learning. Can't thank you enough
I have read so many articles and watched so many videos but no one explained it this well, hats off to the makers
Great for anyone who is not familiar with the Theory of Relativity, well explained and easy to understand! Thank you so much for this video! 🙂
Your Explanation was very simple , clear and straight to the point, absolutely amazing! Thank you so much for such a wonderful video, you earned a sub! :D
This is the best video I came across on time-dilation. Thank you for this.
*By this, it actually concludes that the ones who travel often or frequently are younger than the ones who don't. (?)*
I still don't understand..
Congratulations
And same pinch..!!
It’s actually simple. Just know that everything is based on the equation speed = distance / time. It used to be believed time was constant. Once you find that the speed of light is constant then something else has to give. When observing light from a separate reference frame then distance changes. Now, go back to speed = distance / time. Since the distance changed then the time increased. Hence the time slowed down for the individuals moving at the speed of light vs. the observers from the separate reference frame. Does that help?
Hence why the Speed measurement unit k p h
Kilometer = distance
Hour = time
And light is so fast that it makes k p s
Watch the video again
Space and Time are two separate frames of reference. When dealing with the speed of light, you are dealing with the speed of information. Just like when dealing with the speed of sound. Does going faster than the speed of sound have an affect on time.
Whenever a relativists pulls out their spacetime diagram, just change it to space-information and substitute light for sound. The it will make more sense.
To understand acceleration in time, the fabric of space is composed of electrical energy. Energy is defined as E=mc where c is the speed of light. Speed is distance/time so Energy equals Time.
Energy from the sun warms the ground and accelerates seed germination. Energy from the sun is photosynthesized into plant matter. Energy from the mother hen accelerates embryo development. Energy in the chicken feed accelerates it to market weight. Energy is Time.
Space is nothing. Nothing is not relativite so Space is absolute.
Time is motion. Nothing can go faster than c, so motion/time is absolute.
Information is relative. You see lightning strike the tree before you hear it strike the tree. Standing next to the event, you see/hear it instantly. Move miles away, and it's delayed by the extra distance the information must travel.
In your frame of reference, you experience time normally. Your perception of the universe around you is governed by the speed at which information travels and the resulting distance it must travel.
Simple easy to understand explanation with superb graphics/animations of one of the complex theories !!! Thank you very much !!!
You're a genius! I've watched 100's of videos, many by even well known physicists, just to get a basic understanding to appreciate the theory, but I always get lost at some point because the explanations, illustrations & animations that get a little too complicated or vague. More importantly, their explanations at some point seem to forget that the audience are beginners and fail to address the logical questions formed in the minds of beginners.. It takes a great teacher to recognize that and explain any difficult concept successfully.. therein lies your genius! Thank you!
Thanks!
I think this is the best video that can explain time dilation. I can never imagine how it actually works (maybe because I’m not smart enough😅) until I found this video. Beautiful. Great work 👍
You made me understand 90 percentage of it ✨
Was going to say the same thing
😂😂 bruh he isn't even explaining 10 percent of the theory how do u understand 90 percent of relativity theory it's vast, don't just say things like i understood 90 percent of it it's disrespectful
This helped me understand the subject better than the others I watched. Well done!
BRO YOU ARE LITERALLY A MASTER EXPLAINER. Thank you so much for this video
I feel like I’m the only 1 out of all my friends who watch I learn about this kind of stuff , therefore I feel like I know more than them…. Does anyone else feel like this sometimes.. i live on a reserve in Alberta Canada, although when im out around other ppl I don’t know, I often wonder if they know as much stuff that I know… lol
Same here.. They're only limited to books..
Hi 👋
In the moving train example, the real explanation is due to the fact that the passenger on the left (relative to the platform observers) is closer to the observers at the time the light signal reaches the passenger. Thus, the observed light signal needs to travel a shorter distance to reach the observers, so it arrives sooner. The passenger on the right is traveling away from the observers, and is therefore farther away when the light reaches, so it takes longer for the observed signal to reach the platform in that case.
That's what he said.
Yup, hence, an optical illusion by definition
So far the best video that explains something so complicated very simple way! Thank you❤
That was fantastic! Your explanation of time dilation was brilliant! Thank you for such an informative video.
Explained with awesome clarity and extremely clean graphics …..kudos and thank you …..👏👏👏👏🙏🙏🙏🙏
Excellent presentation of time dilation, one of the best I have seen, congrats!
First time I have seen someone explaining these complex theory in such a simple manner. I loved it ❤
This topic is so interesting that even if I watch 100 different videos on this subject it still doesn't bore me. Btw, your explanation was so much better than other videos that I watched.
This is fantastic. Congratulations!
I have seen so many videos to get the concept of relativity, but this video is the best . Easily explaines such a complex concept.
this is one of the best explanations of relativity I have ever come across, a masterpiece
Crystal clear explanation on such an interesting yet not so easy to describe topic
Very well explained. This is the first time I have understood why time slows down for a moving frame of reference. Your explanation aided with animation are very easy to understand.
I DID'T BELEIVE SUCH A HIGH CONTAINT WITH EASIEST EXPLANATION I EVER HAD !!!!!
I APPRECIATE FROM THE INNER CORE OF MY HEART AND YA REALLY THANKS..
Fruit loop any one.
@@ossiedunstan4419 YUP!!!
bro I don't get why you have only 16k subs, your content is incredible
Already know this will be a banger of a video before I’ve even watched it ❤ thanks man
This is by far the best video on Einstein’s time theory. Very nicely explained. Thank you so much
Excellent video!! It's the first time I understand this subject!! Congratulations!!
first video that actually made good sense of special relativity. thanks
Best video I have ever seen explaining the special theory. Whomever produced this is a genius. Well done. Cheers
Wow thank you. This is the first time I actually fully grasped this concept. Amazing.
This is the very well explained video on special relativity that every student should watch.
Mind boggling and by far the easiest explanation! Please watch all the videos which comes in series before and after this. Kudos to the channel🍻
the way you present the topic is appreciable , even though hard topic seems easy to understand
the best physical conceptual platform.
This video deserves more views honestly
Very very well explained video. I LOVED IT.
Love your videos, man. Good and simple graphics, good explanations, short(but long) enough, chaptered for the ones in a hurry and a comfortable voice to listen to. You'll definitely get hundreds of thousands of subs, just give it a little time, and get a shoutout from @Veritasium
Just one comment. Be more careful with your wording. As you open your video, you seem to forget that gravity amongst other things move just about as fast as light. I'd rather turn it around and say that light is the fastest thing we know. Looking forward to more videos.
I think this video was clearer than any I have seen so far on this topic.
❤❤... I tried lots of videos to understand these orinciples... But this was the most understadable ever found upto date... Thank you so much sir.. 👍👍👍
Easily the best explanation of time dilation !!
Thank you!!
Thanks for making me understand
This is the most understandable explanation.
This is December 25th of 2023. Yes, it's a Christmas day and I am unlucky that I have some issues to celebrate Christmas this year which means no gift for me. So I'm scrolling CZcams and found this video. This really is a gift for me. Thanks gazillion ❤️
Bro you explain it so well, thank you
Thanks! Great explanation!
🤝
best relativity explanation video ever!
thank you very much!
@Klonusk Great video.
I loved the way u explained such complicated things so nicely,❤️❤️
I am curiously waiting for ur next vedio..plss do fast
Fantastic Explanation.
Wow this is the best explanation i have ever listened in this topic ❤
Thank you so much for this video!!!
The light clock is GENIUS - I could never visualize time dilation before until this example.
After years of sort of understanding, i now do. Thanks a lot. Great video .
Loved the explanation. Keep it up..
I have the same way of thinking (visually), and this is the first video I've ever seen on this subject that actually makes sense :-)
Thank you ... THANK YOU! I've pondered over this for years finally just accepting it as something I could never truly understand. But that light shown travelling inside the train being observed relative to the speed of the train by the stationary observer makes perfect sense! 👍
WoW you are a genius , I’am working since two mount on file about this subject, I saw videos and read books in English and Arabic and French , but your videos is so clear and amusing
Excellent video, very clear, thanks
Please post time dilation due to gravity video ASAP ! And thanks for this awesome explanation. 🙏
Very well explained
Great video! I believe time dilation can be better applied to the size of the observer vs the speed of the observer. The closer one is to the core of our planet, the faster time appears to pass for you which can be compared to the microscopic size. The further one is away from the core of our planet, which would be the larger observer, time appears to pass more slowly than that of the smaller observer.
Please never stop making videos pls
A very insightful documentation of nature thank you for sharing some light on such complex issues of physics
This is the best video😍 I have ever seen explaining Special Relativity
Absolutely great video, thank you
I've watched heaps of videos on this topic but this was the first one that made my dumb brain comprehend what's going on. Thank you for that
I never understood time dilation properly until now, thanks for the great explanation.
The train example has helped me understand the theory a lot more, thanks!
Except that the train example, as far as I can tell, is completely wrong!
Neither leader in the train is moving away or towards the light flash, as they are both sitting the same distance from the light flash. How can one say that an observer on the platform would see one leader moving towards the light flash when the light flash itself is moving away from the observer? They are mixing apples and oranges here.
@@jszlauko I think it is because light moves at the same speed to the observer's perspective regardless of where the observer is. And so if the observer is outside the train, he will see light move at the speed it is supposed to, even if the train is moving. And so to the observer outside the train, light within the compartment moves at a set speed, while the two leaders themselves are moving at different speeds, which is why it appears to reach one leader first.
@@paulzhang4810 - I realized my mistake after further research. It’s like you said, in that to the observers, the speed of light is constant. What it really comes down to though is that nothing can go faster than the speed of light, regardless of what it’s being related to. Thus, when the light leaves the source and is heading towards the one leader, normally its speed relative to the ground would be added to the train’s speed, so you’d have the speed of the light relative to the ground as the speed of light plus the speed of the train. BUT, since nothing can go faster than the speed of light, the light going towards the one leader is just the speed of light, as it cannot get that added speed of the train. Thus, the light arrives at the one leader later than it does the other one.
@@jszlauko I think I get what you are saying, but I would like to add a few ideas. EVEN IF the train were to travel faster than light, light itself will still travel at its predetermined speed. This is because light is not a mass -- it is energy. It is not affected by the movement of the train. And so no matter where you stand, inside or outside the train, light will appear to you and you alone to be travelling at its predefined speed.
If you are inside the train, light will travel at its speed. If you are outside the train looking in, light will travel at the same speed, but appear to reach one leader first. It's like Schrodinger's Cat -- there's simply two scenarios in this case and both are real, both are possible.
This is my take on the example, and I'm not sure how accurate I am. But this example explains the experiment scientists did with two clocks (where one clock, brought on an airplane and flown around the world, ended up being slower than the other clock that stayed stationary).
Excellent video on time dilation THANKS!
Really enjoyed this video! It nicely demonstrates a lot of the principles Brian Greene explains in his book “The Elegant Universe.“
thanks for explaning the examples in the relativity book of Einstein.
That is the best explanation ever🔥
It is really very very complicated topic
But you made it easy
Thank you
High quality content 🔥
Oh my God!.. best explanation ever, thank you so much...
VERY well explained.
I was so nervous earlier with my job interview and while waiting I was listening to a song to calm myself because my heart was beating so fast. I noticed that the song feels slower than usual and suddenly it went back to normal. It happened again it slows down, went back to normal, slowed down again, and back to normal speed again. Everything felt so slow for a split second.
The agreement signing on the train is a brilliant illustration. If the train went fast enough the light signal would take hundreds of years to reach party B so everyone on the platform would have lived out their entire lives without the agreement ever being signed but Party B would claim they signed it seconds after the light signal was emitted.
It would be great if you could do a similar video on the twin paradox explaining in plain English where the time actually gets lost for the returning twin, I've seen graphs and formulas but no explanation how the time gets physically lost.
This is how I become a theoretical physicist, love this
