Is Earth Actually Flat?

Hey, Vsauce. Michael here.
In 2003, researchers did the measurements and found that Kansas is in fact literally
flatter than a pancake. Of course, the Earth is not flat, the Earth
is round. Otherwise travellers would be falling off
the edge all the time. Right? Wrong. If the Earth was not a ball shaped, but was
instead a flat disk, like this plate, well with the weight, density and thickness, living
in the middle could feel pretty normal. But as you move toward the edge, gravity on a disk Earth would slightly skew, pushing at a greater and greater angle back toward the centre. My friend Nick from ‘yeti dynamics’ put together
this great simulation. The person and buildings obviously aren’t
to scale but check out how such increasingly diagonal gravity would work.
Although this is a flat disk, it would feel to a runner headed toward the edge, like they were fighting to climb up a steeper and steeper hill. The building foundations behind the runner reflect how you would have to build structures, closer and closer to the edge, so that people living in them always felt like down was at
right angles to the floor – the way we feel it on our big, round Earth.
As you approach the edge, things would get scary. Remember, this is a flat Earth, but it would feel like a sheer drop off. What’s really cool is that contrary to the “don’t fall off the edge” fear, on a flat
world because of gravity, the scary risk would actually be falling away from the edge and
rolling all the way back to the centre. Once you stepped over the edge, instead of
falling off into space, you’d be able to relax. It would be a nice level place. This model, of course, neglects the fact that such a planet shape would be impossible. Anything as massive as the Earth, shaped like a flat disc, would, under its own gravity,
naturally collapse back into a ball. This is why in outer space everything more
than few hundred miles in diameter is round. Or so we’ve been told.
What if gravity isn’t real? What if the Earth is, in fact, flat and science
has been wrong all along? It’s a misconception that Christopher Columbus
discovered that the Earth is round. Virtually every scholar and major religion
in the West accepted Earth’s rotundity, since at least the time of the Ancient Greeks, who,
for instance, had noticed that boats disappear bottom first when sailing away.
And, as you walk north and south, stars pop in and out of the view. The misconception that only a few hundred years ago lots and lots of people believed
the Earth was flat likely began in the modern era, as a sort of insult.
Well, your people recently thought the Earth was flat, so why should we believe you now?
The smear was repeated and published so often it became accepted as historical fact.
“Flat-Earther” became synonymous with “Anti-science”. It might seem flat over short distances, but
over longer ones, well the Earth is pretty darn curvy. The Verrazano–Narrows Bridge, connecting Staten Island and Brooklyn, had to be designed
with Earth’s roundness in mind. Its 2 towers, separated by 1300 metres, and
perfectly vertical, are nonetheless 41 milimetres further apart at the top than at the bottom because of Earth’s curvature. In the 3rd century BC, Eratosthenes measured
the differences between shadows cast by poles in Syene and Alexandria to calculate, more
than 2000 years before rockets and space travel, the circumference of the entire globular Earth,
with, for the time, impressive accuracy. Word got around that the Earth was a round
shape after that. But in 1906, Wilbur Glenn Voliva became head
of a slightly bizarre religious sect that pretty much ran the city of Zion, Illinois. Voliva believed that the Earth was actually flat and he enforced flat Earth’s teachings
in schools in Zion. He also enforced that belief on really anyone
who entered the city. Voliva believed not only that the Earth was
flat, but that the sun was only few thousand miles away from Earth.
Not 93 million. He also believed that the sun was only 32
miles across, not 860 000. He sounds crazy, or does he?
You see, the same phenomenon Eratosthenes measured could be explained by a flat Earth,
if the sun were only few thousand miles away and 32 miles across – the math would work
out the same. Today, with the power of the Internet, modern
day flat Earthers have picked up where Voliva left off. They have quite good explanations for any evidence you throw at them that the Earth is round. Circumnavigation is really just a flat circle path. The round shadow Earth casts on the Moon during
a lunar eclipse could also be made by a flat disc.
Time zones are caused by spotlight sun, and remember how gravity would be totally different
on a disc-shaped planet? Well, they argue that gravity, as we know
it, simply doesn’t exist. The flat disc of Earth is merely accelerating
up at 9.8 metres per second. As for all of the photos and video evidence
we now have that the Earth is round, thanks to space exploration, well all of that material
is completely fabricated. A hoax, perpetrated by Big Globe.
Space agencies, airlines, globe manufacturers. They are reaping the rewards of our ignorant
belief that the Earth is actually round. They know, of course, that it’s flat.
And they’re hiding that truth from us. Is it merely a coincidence that the logo used
by the Flat Earth Society is a projection of Earth, centred on the North Pole, and also
happens to be the projection used by the United Nations? Are these people for real? Probably not most of them.
But this is the crocks of Poe’s Law. An adage that states that at their extremes,
parody of extremism and sincere extremism are difficult to distinguish. Although clever, flat Earth theories are predominantly ad hoc explanations – excuses made up on the
spot that only address one issue and don’t fit all the evidence. Science, of course, rejects a theory if a better one fits more of our observations,
but why the egoistical obsession with OUR observations? A cosmic ray particle could use the very same scientific method we use and conclude that
the Earth was, in fact, flat. You see, at speeds near the speeds of light,
time slows down and lengths contract. One way we know this is that unstable muons,
created in the upper atmosphere by the collision of cosmic rays with the atmosphere, should
mostly decay before reaching Earth’s surface. But yet, we detect a lot of them down here,
because they’re crazy fast speed literally means that, from our perspective, their physics
runs according to a slower clock; and to them, the distance they have to cover to the surface
during their short lives is, from their perspective, much much shorter than it appears to us.
If you’re a cosmic ray proton travelling at 99.9999999999991% the speed of light, Earth
would appear to be only 17 metres thick in the direction you travel. So Earth is flat to them, but round to us. It is ball shaped to some observers and flat to others. There doesn’t appear to be a single most correct-est,
in all circumstances, answer. Susan Haack compares knowledge to a crossword puzzle. New answers interweave with old ones, they
all reinforce one another. The clues are the questions we ask, and the
way the answers fall into a predetermined grid, well, that’s our confidence that we’re
on the right track. But that doesn’t mean one day there will be
a finished puzzle – a complete answer. Recall The New York Times famous 1996 crossword
puzzle that came out the day before the US election between Bill Clinton and Bob Dole.
The clue for 39 across was pretty crazy. You seemed to need to be able to tell the
future to answer it correctly. It simply said, “Lead story in tomorrow’s newspaper (blank) elected”. Well that blank could be Clinton or Bob Dole
and who’s to say which one until tomorrow? There’s no way to know.
But, as it turned out, the answer was Clinton, or Bob Dole.
No matter which you wrote in, all the other clues fit.
For instance, a “black Halloween animal” could either be a cat or a bat. Our knowledge about the outside world might be the same. A puzzle with no answer key, just the reassurance that the answers we think we know fit together,
so they’re probably correct. Though there’s always the possibility that
the answer to one clue, or all of them, will fundamentally not have a single definite satisfying answer. The puzzle may be playable forever. I like what Richard Feynman says about this. “Some people say ‘How can you live without
knowing?’ I do not know what they mean. I always live without knowing – that is easy.
How you get to know is what I want to know.” You know? And as always, thanks for watching.

  1. To people pretending Earth is flat: no need to copy links of videos of airplane flying just over the clouds as a proof that Earth is flat. Every person with a minimum of sense of proportion know that you would not see a curvature at this altitude on a 12700 km diamater globe. So it's not an IRREFUTABLE PROOF as you say!!! You would never see the sun pass under the horizon if it was turning in circle above our head and it will change apparent size depending if it's far or just over your head. This is really easy 3D geometry to demonstrate and even visualize in your head. You know in the bottom of yourself that it don't work so you decided to invent a twisted perspective explication that make no sense in reality. No problem, just put an uplifting or scary music in the video and it will be more effective! When you try to have a cohesive theory to explain not just each observation individually but all of them at the same time, it's where the theory finish to collapse. But you don't care, it needs to be flat so you continue with your assertions! I was a bit sarcastic in this paragraph because, although some person believe gently that this theory could make sense without having too much thinking about it, other are dishonest, pedantic and manipulative.

    It's not too dramatic to think the Earth is flat but some of you believing to a flat Earth are also anti-vax. You use the same reasoning in both case and a very dangerous systematic mistrust for people using science. They try to evite for you or your children to die from polio but you think they are trying to poison you. Do you make neutral researches on both sides or just trust infos going with your already established opinion? Imagine that maybe you are wrong about it and an erradicated disease come back and cause an epidemic causing thousand of deaths just because you have preferred to trust only your complotist news website, the neighbor that makes an arbitrary correlation between his hair loss and the fact he got vaccinated when he was a child or the auto proclamed specialist that tell you with all the confidence he can show that there is alluminium in vaccines and so it's dangerous! Of course, he don't know it's the dose that makes a substance poison. I can create a scary story and make it publishes in a sensational manipulative (news) website myself if I want to convince people that vaccines are dangerous. They will be happy to get a good story to sell. I absolutely not say that people using science never do bad things but in fact we have bad and manipulative people everywhere. You are very suspicious of the (system) but should you not be suspicious about the random guys on youtube that pretend to know the absolute truth? Why these guys are more trustworthy?

    So, would not be more wise and healthy to check for all available infos you can find and not just the one that go in the sense of your established opinion, to get a larger objective view of the situation before to conclude? This is called using his critical thinking. Let your convictions and emotions on the side the time to make full objective researches because otherwise you will risk to be biased in the process and to trust the information that you like more but which could be completely false. Search for counter arguments, false proofs, for fallacious logic etc. Some complotists present pictures they have faked or take a documentary video and make a manipulative montage with it. If you find the original video you can see the real context and you can find the original picture on the net too. The older file is the authentic one. We can all be victim of confirmation bias but with critical tools we can be more cautious and get a larger view. I would recommend you to learn about cognitive bias and crititical thinking. These things should be teach in school for the good of society and to try to eradicate fake news. Be humble, it is not because you don't understand an abstract thing that it is necessarily false. It's not because something is intuitive and simple that it's true either.

    I hope to help some people to think in a wider and wiser way and try to convince them to make more researches before to conclude temporarely about any subject. Don't be rigid, be open to new information that could change your mind but always use objectivity and logic when you are looking for physical facts. Don't look for ultimate truths, just for the most probable, the most rigorous and coherent explication.

  2. If earth was flat, then would it mean that other planets would be flat aswell?
    You see, why do we see the moon is round? Again, if earth was flat then a airplane would fly over the edge and fly off to space right? Plus if earth was flat then the gravitational field and force would suck us in the sun or fly outer space because north pole and south pole is indeed uptop and under each other btw if we dug a hole then we would be on the other side instantly right? So earth is not flat

  3. Michael, you are repeating claims of evidence of a round earth that other people have produced. What you should do, instead, is demonstrate your own proof.

    I believe the earth is probably round, but am rational enough to recognize that this is based on the claims of others, that I have not personally confirmed.

    If you wish to be more convincing, and address things in a more scientific way that will convince actual skeptics (using that term properly, to mean someone who believes neither way without proof), then you should make a video in which YOU TEST AND VALIDATE ROUND EARTH CLAIMS, ON CAMERA. Calculate the curve of the earth based on the angle of the sun from two locations, using an airplane to fly to a different latitude and measuring at the same time the next day. Or something else.

    Saying OTHER people have validated the roundess this way or that is not even real evidence, much less proof.

    You would be doing a service that would convince people who are borderline.

  4. The Freemason Christopher Columbus lied, everyone before him said & have proof via their old maps show the earth is flat! Go research early maps!

  5. if the earth was flat you would see the mount everest in a far distance the people who dont believe me and mike well go away learn instead of being dumb
    also if the earth was flat also the astroids would be angled as straight not curvy just like rain, each rain goes to the ground by each for example theres rain they go down some rain go in the same speed while the others are different speeds if the earth was flat.

    Rain would be in the same speed also its momentum would be 0 its just like speeding time, delay which makes rain go to another direction is spinning earth if the earth was flat, it would totally not cause delay but the rain would move to another angle but like a straight line like this;
    you see it goes to a different angle straightly there are totally no circles: circle would not exist in the shape the clock would not know the time but circle does there circle isnt a word if the earth was flat but its just invented by some people to name it, the sun rays goes straight in 1 direction it would hit us because theres nothing to protect our atmosphere but the only thing that will prevent use is a shade, what shade? Like a shadow; huh? A shadow! That will still exist but the darkness will be total black.

    ok thats what i only know just like this comment pls

  6. 0:44 look how it leans in, crazy because as you go over the globe it’s always at the centre because it’s round lol

  7. There’s a kid in my class who thinks the earth is round but a square but a circle but a sphere that’s only round on the inside with flat gravity the gravity is lying to us and the earth is a continent and he even says it is as big as America

  8. Attention Christian flat earthers. The Bible says “and he created a sphere, and he called it earth”. What do you think now?

  9. I always think it's crazy how our ancient ancestors figured out these things, without modern machine/computer assisted experiments and scientific method.

  10. I have only one question
    Why does this ridiculous idea even exist in modern society? Props to CIA and their psy-ops, I guess.

  11. No flattards would be able to make a argument with out using the words: lies, Nasa, brainwashed, perspective, and buoyancy

    But don't forget the statements : WaTeR FinDS ITs OWn LevEl,
    YoU Are BeinG BrAInWasHeD,
    And ItS ThE LaW OF PeRSpeCtIvE.

  12. If an actual flat earther watched this they would probably say, “No it’s flat, the government is hiding it from us.”.

  13. A question no one has ever asked:
    According to the planers' map, Sweden is halfway between Australia and Argentina. So someone explain to me why flying from Australia to Argentina is faster than flying from Sweden to Argentina ?????

  14. If earth was flat, does that mean if all 7 Bil + humans on earth were to jump at the same time, in the same area, we could cause it to spin?

  15. Math says that every question about our universe doesn't have one answer so why not two. In fact most of them dont

  16. Gravity is a made up force that is a theory needed to make the heliocentric model work. Strong enough to keep oceans and everything stuck to it but light enough for bugs to fly. Pretty convenient force to have when you need your globe model to make sense.

  17. Where does this Earth elevator idea come from? It's fixed immovable. things that are denser than air fall. Just like things that are denser than water sink and vice versa.

  18. Hey stupid flat-earth men, if your Earth were flat, there would always be a day in all of its territory. And from each point of the earth there would be seen the same constellations!!!

  19. Ermm, I've looked up on google if the earth was flat or not but i found none that said its flat.
    I'm Trans so is gooogle not showing me real proof that the earth is flat because Google is transphobic?
