Space is where things happen. Time is when things happen. And sometimes, in order to really look at the universe, you need to take those two concepts and mash them together. In this first lesson of a three-part series on space-time, hilarious hosts Andrew Pontzen and Tom Whyntie go through the basics of space and time individually, and use a flip book to illustrate how we can begin to look at them together.
Lesson by Andrew Pontzen and Tom Whyntie, animation by Giant Animation Studios.
It reminds me of Albert Einstein's quote : "If you can't explain it simply, you don't understand it well enough."
It's so amazing!
Yeah , it will remind me
That's Bohr
Or maybe you think it's simple because you are Einstein but other people still find very complex
That's Feynmen's qoutation
Aww I've never heard that quote before but it's brilliant!
me: trying my hardest to understand what the heck is going on
my brain: why the heck do they only have four fingers per hand
Kun Feng 😂😂😂😂😂😂😂😂😂😂😂
lol
Don’t judge them, you only have 4 fingers per hand. The other one is a thumb.
So m not alone lol
Either this animation has explained the concept brilliantly or its just making it too simple to be accurate.
Totally agree
Too simple to be inaccurate* you mean
@@amoghskulkarni No, too simple to be accurate
Lol I didn't get it
Ok
As a person who hated physics in high school, thanks for making me feel intrigued by physics again. I'm actually clicking the part 2 video. Awesome. This shows how well-crafted animation videos can make abstract ideas concrete to layman like me.
I find that those with the intelligence to first know the word 'layman' and secondly to then apply it to themselves are rarely ever a layman. Socratic wisdom and all that jazz.
Fundamental Sciences are Loved!
Still don't get it
Have u watched second and third part of this video.
Watch xkcdhatguy
Pick a number between 1 and 10
Seek and you will find!
(I don't get it too but I obviously don't want to know it bad enough at the moment)
Each moment you are a different person.
i love how enthusiastic the person talking is! :D
wtf am i doing here.
i got a test tommorrow and now im just watching sone guys talking about spacetime
How was your test?
Have you finished the test after 4 years?
Are you INTP?
Just listen to me, I'm not kidding.
Last night I was wondering about space-time while sleeping and the next day i got this video on my recommendation. I have never searched anything related to space time ever in youtube or in Google.
you actually moved to future in your dream (4th dimension) and played this video unknowingly. sleep again to come back :P
Let's try. Hate it too xD
I'm 18 months old and I understand this.
Alex Leaud you can write, good job. I could write at 3 months old.
I could study about space and time when i was 5 years old
Aj Styles
Pathetic.
i was born with it coz my mom watched this ted clip!
Please, a real overachiever understands this as an embryo.
I'm just in stomach
Schools: No! Youu can't learn physics and animation together
Ted ed: Hold my cup😜
It's probably the only video on RUclips that has defined spacetime in the best possible way.
i feel like Einstien
This is so ironic :-)
@@robertkuhn90 lmao
@@robertkuhn90 why lol
@@gloriawang5608 tbh i am not dure myself but i think it has to do that einstein created these theories.
@@blauwbeer556 oh okay well then that's just a misuse of the word "ironic"
That moment when you're a seagull and you become a cosmic ray. Mood
This is absolutely the best explanation for the space time diagram.
These fellas are ADORABLE!
xD
Wow TED-Ed, you really makes it all sound so simple. I really love this animation.
When you try to explain space and time to others but they just assume I'm talking about clocks lol
Can we take a moment to appreciate the animation and the narrator ?
My smart friend: space-time
Me: is that like face-time?
This has got me thinking about both space time, and how/why they went for 2D/3D animation at the same time
Once I finally was able to realize that time only applies to objects within space and not space itself the relationship between the two became much more clearer for me.
That was the best relativity explanation I've ever seen.
What a brilliant illustration.. Relativity isn't so intuitive and you and its not always easy see the picture in the equations.
Great job!!
im 13 and i watched this video voluntarily without any knowledge and i get this
i have literally know idea what they aretalking about
Flipbook is best way to explain space time. Couldn't find any better video explaining space time like Andrew and Tom did
Imagine you all are in the
Space time flip book !
Excelente vídeo. Philochrony is the theory that describes the nature of time and demonstrates its existence. Time is magnitive: objective, Imperceptible (intervals) and measurable (duration).
For us humans, we experience space differently to time. We can move backwards and forwards and sideways in space but we can only move forwards in time. Also we can move through space faster (in less time) but it seems that time decides for us how fast we move through it.
Actually, our movement through space decides how fast time moves relative to everyone else and our brains interpret the rate at which we experience time. For instance, animals can experience time differently than humans. But you are right that the direction we move through time doesn't seem to be up to us. Probably because of entropy.
@@CitpeksAmi I don't really feel like I understand it. It's strange to be so familiar with space and time and yet not really be able to grasp it all.
People assume that time is a strict progression of cause to effect, but *actually* from a non-linear, non-subjective viewpoint - it's more like a big ball of wibbly wobbly... time-y wimey... stuff.
only if you have a TARDIS or a really nice bow-tie because bow-ties are (what?) cool
PancorRath If you were a true whovian, you would know that it was David Tennant that said that.
czechmate30
David Tennant? pretty sure it was Matt Smith who said and etch in stone how cool bow-ties are... along with fez, fish sticks and custard and being possibly the dorkiest of Doctors
Sounds like something Rick would say...
Excellent video, beautifully animated. Physics teaches us what we should know but always forget, 'it's always good to see things from different perspectives.'
I think that goes for all the negative commenters who say this is 'too simple'. Too bad not everyone can be as worldly or as intelligent as you all. Pff
Bilal Ahmadi I
If you can explain it simply, it's an indication that you understand it
My brain got lost somewhere in space time
Space and time are relative, the more time I spend with my relatives the more space I need
This should be shown in every school and institute
I loved this explanation but sometimes when I don't get it properly I just re-watch it again and again......Thanks TED Ed for brilliant content.....😌
Maybe one of the few ted ed vids i finished not having to gasp for more air.
Nice video :D
I'm still sure that time is a big ball of wibbly wobbly timey wimey stuff but well now I know some of the details.
:D
On a scale of 1 to 10 how much of the video did you understand
Me: yes
I thought I had a decent understanding of space-time via Einstein's special theory of relativity. So I was surprised that I really didn't understand this video. Is it just me?
This is classical physics. The next part is special relativity and Einstein.
as an animator who loves learning about space this makes me happy lmao
Very nice, has taken me just one step further to understanding brief history of time, going to read it again. By far, better than rest of the videos on space-time.
めっちゃわかりやすいです！
My eyes: watching
My brain: what's for dinner?
Finally an educational video of spacetime I can keep up with.
I want so hard to understand! I need to understand! But even when broken down like this into bite-sized chunks, my brain struggles. But alas! I will persevere!
probably one of the best explanation of space-time iv ever seen
Space - Where things happen?
Time - When things happen?
Me - Why things wanna happen?
Mind blown
I actual
I learned something
How does gravity warp space time? And what does warping space time even mean? Does that mean gravity slows down time or speeds up time?
Got the answer? Kindly share it with me. Even i wanna know the same. Please.
It doesn't really as far as we know. That is someone's theory to explain certain phenomenon.
I wonder if they are going to come to the conclusion that time progression is actually an illusion and that all time (past, present and future) exists simultaneously as does all possibilities.
Good video. I like the idea of baby steps in explaining complex topics.
Pls make a second part
Even if you create a whole one hours video instead of parts, we're going to watch it
Please please please make a series with them
24 FPS ewwww...
I bet you didn't even notice it in like every movie ever? Other then Peter Jackson's the Hobbit, which was in 48 fps. If it's slow motion then it's obviously more then 24 fps, but 24 fps is the industry standard.
I was being facetious, nothing to serious man
Fair enough, cheers!
Sorry for being that guy lol
@@odddy okai
As a visual/kinaesthetic learner, I learn more through watching RUclips and cross-checking info in a Library than I did over 5 years and $50g worth of university 😓
R u doing this on head squeeze also, I loved the vid about time travel
IS there any video or documentary that explains the "fourth dimensions" (even higher).. "wormholes" and "portals" and time travel and physics? Something that can be easily grasped?
I know a few , are you still looking for some ?
Elegantly put. Well done.
2:39 he said I guessed it........but i didn’t
sad :'(
He was referring to you from rush hour
Amazing
Thanks
I watched tons of vids and this one was the only one that I understood thank you very much
It is crucial that you understand the difference between the Newtonian world view that the axis’s of your graph remain unaffected by motion. You simply rotate the graph within them to get the relative perspective you require. But the speed of light is “special “ you can not rotate its world line when trying to view from the perspective of a moving observer. So the only way you can get the moving observers world line vertical without affecting the world line of light is to consider the graph paper as a rubber sheet, call the sheet the space time continuum, a single thing, and stretch and squeeze it in a manner that results in the observers world line being vertical, but the world line of light remaining unaffected.
The result will distort the time and space axis, which Newton said did not happen anywhere in space at any time. If you read off the position of a point that has suffered distortion on the undistorted axis, it will show a smaller reading than its original position before distortion had taken place. Time moves slower for a moving observers and distance shrinks it the direction of motion, but they would both agree on the speed of light.
Time does not break, time ceases to exist at all being
transformed to the next dimension. Time is just an energy and all energies are
transformable.
Time is energy? Really?
@@aman26452 Really. Everything is energy. Time belongs to the dark matter. The dark matter consists of energies. If you manage to transform the physical vacuum called the dark matter you can transform any energy. Will show the demo video soon about the device generating a new renewable multiplying the input power of electrical current by several times at the output. And we are planning several more videos about transformations this year. All of them are lab videos promoting devices in work.
i really did not notice time passing.good work
Better explanation than a textbook. Thank you TED
Far better and understandable explanation than pbs space time channel
I haven’t slept for a while and figured all this out and tried to explain to ppl and they think I’m crazy
Cant wait till the next animation!
Absolutely mind blowing
Inaccuracies may be everywhere - but It’s not because the explanation is simple.
E=mc2 is very simple isn’t? It takes a hard work to be simple.
Love your videos 😊 thanks for making them
The question is how do we overcome the need for those extra panels
Wow. You can create a flip book that does this too I bet.
Flip through with pages straight, then arrange them diagonally and flip through for a different perspective. Right?
after big bang, time was moving forward and our reality flip book just flip at the rate of the remnants
This video is Genius
In Australia we measure spacetime as "kilometres per hour". my car strangely enough has a meter just for this purpose.
Illustrated as motion.....
Great! Very well done.
Where's part II?
The next animation needs to be today!
"Newton says that gravity is instantaneous but Einstein says that the speed of light is the speed limit of the universe so gravity can't be instantaneous."
I could not get any of that so I want to ask those with knowledge that what does Newton mean by "gravity is instantaneous", how does Einstein know that the speed of light is the speed limit of the universe" and how are time and gravity related?
Thanks in advance for the replies.
This effect is known as gravitational time dilation". ..gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds... Hope this helps. I myself is in the process of learning. Not really equipped enough to answer all your doubts. 😊
gr8 stuff!1 thx. any links to parts 2 and beyond, plz?
Isn't this what you call a frame of reference? MIT has a great video as well describing what this is.
4thandspring link??
it's like The 11th and the 12th dr. giving me a good explanation :D
can I ask a question? Imagine we have two ray of light coming from opposite direction and meeting at a specific point, they have opposite phase so when they reach the point they cancel one each other. Now what happen with the energy of the two ray? get transformed in the dark energy?
Today, Prof. AngelO´ Contreras, proposed that Dr. Albert Einstein was wrong to define our dimension as “space-time”, considering that time is only a rational perception, ruling out that it is a form of energy. Under this analysis, he argued that matter is the energy of matter and force its fundamental fuel. In this order of ideas, the dimension of matter is the “force space”.
However, he argued that time could be rational patronymic energy, but rules out that it exerts force on matter, thus ruling out that it can be considered as a dimension of our physical nature.
The Sagnac effect proves that 1 observer travelling towards the light in a curved line path measures the speed of light as c + v . The key is that the radius of the curvature can take any value in the formula. I chose R tends to infinity and I find c - v and c + v in a straight line.
That was a nice bit of mumbo jumbo......
Ok, where is the next animation? The interest is peaked!!
Instead of complicating things, you can simply say just like length, breath and height, time is also a dimension. That gives us our 4 - D. And that's true we move through time as well just like we move through length, breath and height. Although there is an exception too, we haven't yet figured out a way to move back in time
Time is not spacial......
I watched it twice now. I understood clearly each word . But my brain still cant process it
Great video, thanks TED
Me: HEY I PASSED SCIENCE ONCE I SHOULD TAKE ON ALL OF SPACE
future me: why can't i just h a v e a b r a i n
this makes it so clear
cant wait for part two!!!
why is a stopwatch a better clock than a sandclock? If a 1 mile high skyscraper has 2 clocks at the bottom and 2 clocks at the top, (one of each type) after a day the sand clock at the top of the tower has barely moved whereas the stopwatch has moved faster than their respective ones at the bottom. YET one FULL day has passed for BOTH clocks. Perhaps, we are using the wrong reference clocks? It is obvious that a sandclock is a gravitational clock BUT whose to say that an atomic clock isnt affected by gravity but in the opposite direction? A relatively reliable clock is the earths rotation around the sun. We know that is fixed.
but why would it fall apart at a higher velocity
Time in space is different in space because it’s a fourth dimension as it’s not relative to mass it’s it’s own entity. Mass & gravity bends space, so because the mass is moving it’s moving fast it’s moving slower through time.
Your accepting way to much as fact...
Is the world line similar to a distance vs time graph?
They proved that our lives are mere animations.....
Simple but very useful this time I got it thank you very match please some more
Wow pbs did. Videos about these lines and I didn't get it but that was explained so well...bravo. And thankyou
1:42 let's try this would playing it at *0.25 make us see every panel one by one
Really nice! Thanks alot!
