Albert Einstein’s theory of general relativity, published in 1915, defined gravity as the influence of massive objects, like planets and stars, curving space around them. This was very different from the way Isaac Newton had defined gravity over 200 years earlier: Newton described an attracting force that kept planets and stars in orbit with each other. If Einstein was right, then light would also bend near massive objects. And in 1919, two British expeditions set out to test it by photographing a total solar eclipse. By comparing the position of stars with the sun in front of them and another with the sun elsewhere, Arthur Eddington and his team proved that the stars’ apparent positions moved during the eclipse. This was the first, but not the last time Einstein’s theory of general relativity was tested and proven, and Einstein became a celebrity overnight. He remained a pop culture icon for the rest of his life.

I live in Sobral, Brazil. We have a museum dedicated to this event, and a statue of Einstein here. It's nice to see that this town was a tiny part of this important event in history.
Parabéns! Sua cidade fez um parte de história...
Congratulations. Im so proud of your place.
Sou brasileira e nao conhecia essa historia. Espero poder visitar esse museu algum dia. Obrigada por compartilhar!
Que doido
I would like to visit Brazil
Fun Fact - Albert Einstein did not get a Nobel Prize for his theory of relativity but did get a Nobel Prize earlier for explaining the photoelectric effect which he is lesser known for.

@@randomdude9135 I mean yeah, I think I do think? Dunno about the others though.
@@randomdude9135 // Well, it's been confirmed that you don't think at all...
I really love that this video doesn't omit the fact that Newton also predicted a displacement, or that the data was clear, but not perfect. Most pop-science tellings of this story go like: They held the two photographic plates over each other and there was a displacement and therefore Einstein was right. Good job for taking the time to tell the true story. Please continue stressing that science gains knowledge from careful observation of messy data, that is at the edge of our ability to measure.
Why did Newton predict that celestial objects would be displaced? Was his miscalculation a matter of degree, or was he calculating the wrong thing-something other than the effect of gravity on the light of the stars?
@@AisuruMirai If you're asking why the data didn't perfectly match up with Einstein's predictions, it's because the data itself was not accurate. As time went on, the instruments used to measure the data improved, and so did the accuracy of the data.
i cant find no link for Newt's prediction, PLEASEEE HELP!
@@vinayakvineeth9433 I am asking why Newton predicted that stars would be in the wrong locations. It seems that if his prediction was simply off because of a miscalculation, we would call it Newton's theory rather than Einstein's, and Einstein would receive credit for correcting the theory. Without any prior knowledge of Newton's prediction, my guess would be that he was calculating something other than the effect of gravity on light.
Newton thought of light as a stream of corpuscles with mass. In fact, his explanation for refraction was that the particles in the denser medium pull on the corpuscles through gravity. Calculation using Newtonian gravitation was wrong because the theory itself is inaccurate when dealing with such situations, flaws including treatment of space and time as absolute entities and failing to account for the finite speed of causality.
The idea that a Solar eclipse can be used to prove the Relativity theory was suggested by Einstein in 1911. The first expedition to prove Einstein theory was planned for the 1914 solar eclipse to be seen in Southern Russia - and this didn't happen due to the Great war that just started. The 1919 expedition was the second attempt.
True, the whole story of Einstein trying to prove his theory is a lot more dramatic than the video implies. For a start, he spent YEARS planning this, with world in a war, and with many people considering him an oddball of a scientist.

Just a small comment: You can't "prove" general relativity ... or any other theory for that matter. You can only confirm that it predicts the data more or less correctly. General Relativity is more precise than Newtonian Gravity but that doesn't "disprove" Newton - Newton is simply an approximation to a more complete theory that gives good predictions in a certain range. General relativity is probably also just a good approximation of a more complete theory of gravity - e.g. one that includes quantum mechanics.
Not trying to be a stickler but trying to clarify for when the anti-science crowd shows up...
@@somethang2865 thank you. I had enugh with people who takes theories liturally. For example time traveling. Even though in spacetime diagramm time is just like a spacial dimension and relativity can predict messurments that dosen't mean I'm a liturally a 4 dimensional worm in a hyperspace who experiences his own 3d dimensional cross sections in order from low entropy to high entropy. Like I don't liturally blown away by arrows in a river.
I don't understand how can the guy in the video forgot to mention the important fact that it took 3 solar eclipse and not just 1. And then they liked you comment and didn't even correct their video or add some pinned comment

Very excited to see how important that photo of the black hole is in a 100 years like the Einstein one
Imagine this, we just lived through the first image of a Black Hole and 100 years later another media company will be making a video on this very time period and saying how that picture changed the course of time.

The star picture had immediate effects. The black hole picture just builds upon that. Nothing new.

I doubt any news will come of it... because it's a fraud. That black hole picture is only a compilation of about 6 pixels worth of information filtered through computers to produce the image that astronomers WANTED. It is not the product of a black hole, but rather countless data rearranged and sifted to fit a pre-existing narrative.
There is little, to no raw data given on this black hole picture, only the fabricated image pushed out the the press.

Is it just me or I learn more in internet than in schools, youtube helped me to love science, history and more while at school I always hate them
The internet has more room to store as much literature regarding various topics compared to some rinkydink school textbook. And people on RUclips have more freedom to act goofy as opposed to your teacher at school. Doesn't mean that schools don't teach you anything.
I mean on the internet it is also specifically presented in an entertaining style. Vox is great but it's still a media company first and foremost and that means that they have to focus on making their videos in a way that specifically attracts viewers. In the case of Vox that is probably a net positive thing because they don't skim over the facts or simplify things too much but other people might do that. Ultimately science and history are also a lot of boring research but sometimes we need to see the wonder of it before we get interested in doing the hard work involved. And I think a lot of schools go about teaching these subjects in the worst possible way and there are also other restrictions such as budget and the teacher's energy. An editor at Vox obviously can do multiple takes of a single video to get the right energy and they probably have a few weeks to make each video meanwhile your teacher might have to prepare 6 hour of classes each week while working a second job. What is clear to me as someone not living in the US is that the amount of stress American teachers face seriously impacts their ability to deliver good classes and as such the students suffer for it. Though even here I think sometimes schools do a bad job of teaching science since they don't really take the time to first inspire their students and then get into the nitty gritty.

There's a good movie about this from the BBC a while back. It's called Einstein and Eddington
I miss the days when Scientists were like celebrities back then.
It is because there are no scientist alive who has discovered something about universe like Einstein did.
Stephen Hawking also died a few years ago
Do your research and you'll see there are still a lot of famous scientists in a "celebrity" status around. The reason, why you can't see them in mainstream media, is because there are a lot more distractions these days.
@@s_ame1135 I think that was my point.

I’ve never seen Einstein look normal 😂
He aint human son
Einsten when he was younger looks like my dad when hew was younger and I don't know how I feel about that
A genius NEVER looks..."normal"!
That's because he wasn't normal
THE ULTIMATE, TOP DOWN, AND CLEAR MATHEMATICAL PROOF REGARDING THE FACT THAT E=MC2 IS F=MA:
Time dilation ultimately proves ON BALANCE that E=mc2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Time is NECESSARILY possible/potential AND actual IN BALANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity ON BALANCE. Gravity is ELECTROMAGNETISM/energy.
Great !!!! QUANTUM GRAVITY !!!! E=MC2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. What are the EARTH/ground AND the SUN are CLEARLY E=MC2 AND F=ma IN BALANCE. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. The stars AND PLANETS are POINTS in the night sky. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. BALANCE AND completeness go hand in hand. It does ALL CLEARLY make perfect sense. GOT IT !!!! THE SKY is BLUE, AND THE EARTH is ALSO BLUE. Great !!! Now, think about the man who IS standing on what is THE EARTH/ground. Perfect !!!!

I find myself to be in a different world when watching the science documentaries.
Really fantastic experience to be born as a human.😀🙂
It's amazing that the black hole picture was taken 100 years later, like if it had been an anniversary celebration on purpose.
100 years ago with much less technology we have today Einstein and the other scientists achieved so much. imagine if he had the technology we have today.
Always exciting when a Darkroom vid gets uploaded.
This is part of relativity’s interesting history really nicely presented. Well illustrated, well told, nice soundtracks.
This is such a great video! Awesome work Coleman!!! These are the type of videos that make Vox videos a must watch for me. The mass bending space graphic was done so well! Keep up the good work!
The part about them working together during a war proves that love for science is universal. Made me tear up...
Both were pacifists that's way Eddington decided to test Einstein's theory.
have seen a hundred videos on this topic. By FAR the best one
was waiting sooo long gor next video in this series
I don't care if the next videos took another 2-3 months, but please never ever stop making these groundbreaking documentary bits cause it's jaw dropping, and enigmatic.
Things people discovered hundreds years ago, still go over my head.
Einstein: "I have a new physics theory called the "Theory of General Relativity", but I need a way to prove it in practice"...

Great scientists working together and going for expedition in other parts of world in order to gain solid proof of one of the greatest theory. That must have been a interesting project. After all its Science!!!

Can we a 'll just appreciate the track from 3:38 - 4:00.....loved it
I love the fact that einstein was focusing on the stars while the world was at war!
Not entirely true. He was very much focussed on the war too. He wrote a pacifist manifesto denouncing the war, which almost got him thrown into jail. He was an ardent pacifist and so was Eddington. Two pacifists on either side of the war came together in mutual admiration and the love of physics.

First sentence of the video is incorrect. The sentence should have been, "The only way to see the stars around the sun is during a total eclipse." This is important to point out because it is important to the setup of the experiment itself.
Im a bit confused regarding the explanation. The light from the stars would bend regardless of an eclipse. How was the original position of the stars mapped?
@zhen I had the same doubt. Can someone explain this

I wished Einstein was alive to see the black hole picture in 2019. Would had loved to know what he thought.
Einstein ridiculed the idea of black holes
@@KaranSingh-jr2eu Einstein didn't ridicule black holes, its just at that time it was hard to believe. Remember that his theory predicts white holes and Einstein Rosen bridges as well
Or if Ramanujan had lived to see his formulas finally verified a century later.

Thank you so much for the video, loved it. My long-standing doubts were cleared.

Buddy what an amazing explanation. I watched few videos before this one and your explanation is10/10... Its time to follow your channel.
I dont usually hit the like button let alone comment on a youtube vid, but man, this vid brought back some memories of my love for physics back in highschool. Sadly, due to personal reasons i could not pursue physics but I am currently a computer science student and i spend most of my free time teaching myself physics. I do love computer science but there is something about physics that I could not just let go.
That man was a sheer genius with incredible mental ability.
I remember seeing that image of a black hole for the first time. I had waited for it for years and was so hyped. It's nearly strange to feel that much joy over something like this.
Thank you for the details! Especially I liked the "effect 500 times exaggerated" photo!
The universe's indifference to us is both beautiful and terrifying.
Squ1: interesting that you mention that. Think about popular science fiction over the last several decades. Usually takes one of two approaches: 1) Alien species are friendly and come to Earth to help us or to get our help or 2) Alien species want to dominate us or destroy us. Either way, we humans view Earth as the most important place in the universe. In reality, if there are indeed alien races out there somewhere, they don't care about Earth at all or even know of its existence.

This is awesome, I have never understood the theory of relativity, how did Einstein manage to create those theories without observing in the first place, true genius!
It takes an open mind to look at a thing from different points of view and correlate the wider paradigm.
General relativity is the result of special relativity. Special relativity was made because Einstein was thinking why light never speeds up when omitted from a moving plane and the paradoxes that should have been visible when light doesn't work uniformly, which none was found. He then concluded that the speed of light is constant because it is the time that slows down, and then expanded on this in general relativity to settle what that means for big objects and gravity. Concluding that the universe is not in 3 dimensions but rather in 4 (including time) and that big masses slow time down (aka curves the space-time plane). We don't know why this happens yet, but none the less, this change in the speed of time, results in gravity. And then continue the math to get to other predictions of the general relativity.
It didn't happen out of thin air, there was in fact a logical path to all this.
Simple answer is Mathematics.
Basically scientists (including Einstein) started with known theories which were proved by practical experiment, asked some what if questions, worked out solution under the bound of mathematics and arrived at equation.
To prove if equation is write, they observe the scenerio and if we get the data like what was predicted by equation, scientists discovered new law of physical world.

I'm still waiting to see my first full solar eclipse 😅
I've been under the path of a total solar eclipse but unfortunately it was cloudy at totality; we didn't see the sun until a few minutes after totality. We were on top of a small hill though, so we saw the shadow sweeping across the land towards us before darkness hit. Closest I've been other than that is 93% coverage in a 2015 eclipse, which was enough to produce strange shadows and a general feeling of unreality even though it wasn't total. I'm hoping to be in Spain for the August 2026 eclipse, which should have a reasonable chance of clear skies.
With my surface level knowlege of physics i still find this fascinating. Light has no mass so if gravity is affects matters with mass how does it bend around the sun. Either light has mass or gravity works differently as expected.
That's the point of Einstein's gravity: It doesn't affect mass. The mass of an object like the sun distorts space-time. Light isn't bending. It's travelling a straight path through curved spacetime.
@@ProfessorEGadd I still couldn't wrap my head around this radical shift in the understanding of gravity. The photo evidence really solidified it for me.
