Surveyor here. i can assure everyone that there is no other group that wants the earth be flat more then Surveyors. It would make everything so much easier.

Flat earthers seems to actually believe that there is a real debate about the shape of the earth. They don't seem to understand that flat earthers are just entertainment for smarter people.

Not too many flat Earther jokes are funny, but I think this one's pretty good. Flat Earther dies, goes to Heaven, meets God. Flat Earther: "The Earth really is flat, isn't it?" God: "No, it's a globe, just as the scientists say." Flat Earther: "Wow, I didn't know the conspiracy went _this deep!"_

I'm a flat earth surveyor, what I don't understand is why nobody will hire me. 😂😂😂😂

Just as easy debunk is my military service. 1) I used gyro compass to find rotational north for artillery. 2) I calculated the compensation for the coreolis effect for artillery. 3) I live at the coast of Sweden and have seen 100,000+ big ships disappear bottom up over large distance of water. 4) I can use GPS in the middle of the ocean 5) I have seen a sunset.

The only thing flat earthers fear, is sphere itself.

"No amount of evidence will ever persuade an idiot" - Mark Twain

I'd wager there aren't many flat earth civil engineers either. I had a course on the basics of surveying in the third semester and we accounted for the curvature. At our rather small scale it were mere milimeter and centimeters but still, it was there.

Spent 30 years as an engineering surveyor. Longest traverse I ever did was over 300 km for a pipeline survey. Absolutely had to correct for curvature on that one :)

As a yacht captain I have hundreds of basic exaples of how the flat earthcannot work in reality.

My brother is a civil engineer. When I was about 17, I spent a summer on a large build project. Part of my job was to hold the staff while he took a reading with the theodolite. He explained about how he had to allow for the curvature

The reason there are no flat earth surveyors is that jobs like this are usually carried out by grown-ups.

I've been a surveyor for 45 years. Only since the rise of social media have the flat-earthers become a thing. This is the first RU-vid video I've seen that actually refers to the most qualified experts on this subject - Land Surveyors. My whole life, whenever a flat earth argument came up (which was rare), I would say the earth is round (actually an ellipsoid of revolution, i.e. a slightly flattened sphere caused by the earths rotation), people would defer and accept that statement. Social media has developed this new cult with sh*t for brains, full of self importance.

I love the way that the surveyor phrased what he said in the next to last sentence of his comment: "it is a disappointing marriage of egotism and willful ignorance". So well said!

A poignant note from the travelcroc web page which should challenge flat earthers: "Can you see Cuba from Key West with binoculars? The fact that Cuba is only 90 miles away from Key West makes people sure that they could see Cuba as long as they had a high-powered telescope. But the problem is not in your eyesight or your tools. The problem is that Cuba is below the horizon as the earth curves. Every now and then people claim that they managed to see Havana’s city lights at night, but they have failed to prove their claim."

Why are there no "flat earth" Surveyors or Sailors? Because we either use or rely on the fact that the Earth is a sphere. Flat earth idiocy would be fatal in either of those two activities. PS: I am a retired Surveyor/Cost/Project Manager and still (at 77) a regular sailor.

I love how there are hundreds of industries like surveying whose science wouldnt work if the Earth were flat (not just NASA), and how most of them predate NASA (George Washington was a surveyor..) and it's still not enough for flat earthers to comprehend.

I have a fairly unique perspective as a licensed pilot, AND having used work on a survey field crew. I also helped with the drawing of the maps in ACAD. We absolutely 100% had to take the earth curve into account. Particularly when using GPS gear, and when surveying long distances. As a pilot i can confirm i have never once had to push the nose down to follow the curve of the earth. This is NOT because the earth is flat however. It is because wings will follow what ever pressure plane you are currently setup for. (i.e. power and trim) therefore regardless of being on a spherical (moslty) planet, the plane will travel at constant altitude above the mean sea level. Flers have absolutely no concept of even the most basic of physics and have become incapable of the basic reasoning required to gain it.

I used to be a land surveyor and I will tell you one thing. If we EVER brought back data and the civil engineering department decided that the 7 miles of line that we cut to install monuments for a construction project and all the money and time and work to gather the data points and elevations and control points we worked on just to have them not take into consideration the curvature of the earth……the company I worked for would have been probably sued and never ever received any more projects to bid on again. The thought is ludicrous. I’m so glad that you made a video depicting the fact of the Land Surveyors work. I have not surveyed in over 8 years and I have never become an actual licensed Surveyor in the United States, but I was a Rodman and an Instrument man for over 10 years and I am pretty positive that the Earth has not flattened out since then. I unfortunately got pretty sick and had to stop, but I can tell you I learned enormous amounts of information about geography and the land and in CT the Northing and Southing grid system they use and I couldn’t help myself to be curious about how the Flat Earth individual thinks. Once you get a grasp on Land Surveying there’s no way that any person with a brain could think the Earth is flat. But I still stick to my guns and believe that it truly is a mental illness and I really don’t think it can be cured.

I find it so funny when Flat-Earthers tirelessly parrot 'the Earth is level', even though according to surveyors level lines are curved. 😂

I found that exact discrepancy on a surveying field trip when at college.... We had an undulating 1km area to survey with highly accurate theodolites, triangulating in 3 planes and found, as we got to the corners that our distances overlapped slightly... All four groups had the same 'error'... Our tutor helped us figure it out... It was a " duh, of course" moment.

Asking "Why there are no Flat Earth Surveyors" is like asking why don't mirrors have people living inside them. Because it's simply impossible for either of them to exist.

Do you think people who believe the earth is flat will understand that math in the book? It's easier for them to say all surveyors are paid to lie to us about the globe... For some reason

As an amateur astronomer, i rely on the round and rotating earth every time I observe. My mounts, my star charts, my planisphere…none of it would work on a flat earth.

As someone with two civil engineers in the family, I found this fascinating. Unfortunately I expect a flat earther to actually take a surveying course around the same time they get around to actually doing some celestial navigation. 😆

Now i understand that the leaning tower in Italy was surveyed by a flat earther. Brilliant 😂

flat earth surveyors: "why all the projects we do fail ?" every non flat earther on the planet: "I wonder why"

I'm a land surveyor and demonstrating the curvature of the earth across a lake is the most basic of tasks. Why have none of us been commissioned by flat earthers to put it to rest?

Surveying requires mathematics. That alone disqualifies any flerfer to make any statement about flatness, leveling, and/or horizontal.

All flat earthers after this video 'la, la, la, can't hear you, can't hear you, la, la, la'

Your dog is far too wholesome. I’m glad they are part of your videos. :)

I'm a geodetic trained surveyor from the military and now I'm a licensed land surveyor in Virginia of course a construction site would not need to adjust for curvature but let me assure you you can't cover any distance at all without correcting for curvature or your survey won't close.

I have been a licensed professional surveyor in the US for 50 years. I can tell you without a doubt, the earth is not flat. I have run differential levels for miles and then measured over those same miles with a total station (theodolite and electronic distance measure device combined). You have to take into consideration the curvature of the earth to correct for the zenith angles measured.

Fortunately, engineers in the US can no longer perform boundary surveying without a surveyor's license. Most of them didn't have the necessary education in boundary and legal principles to make proper decisions and usually tried to apply engineering methodology to boundary surveying which resulted in countless boundary problems that we'll be trying to deal with forever. They're restricted to design and topographic surveying now.

As a civil engineer I did have to take surveying in college (40 plus years ago). I went to school in Ohio and the example of doing level 3 surveying (not taking into account curvature) were the small county roads where about every 10 miles they made the correction at an intersection. These never lined up across the road and had an offset. I think a lot of these intersections have been tweeked but you can still run into them occasionally.

My Father was a Chief Surveyor for the Ordnance Survey in the 60s, 70s, 80s and 90s,. He and his teams mapped the whole of the UK one team from the North to South and the other from South to North, and he told me that they had to account for the curvature of the Earth. Their maps were less than a quarter of an inch out in the two teams, which is pretty damn good. His name was Ronald Charles Layton, should you care to find out if he existed or not! He died in 2013 alas, he was a fine man. I still have some books and a beautiful clinometer from 1911....

You sir, are the creme de la crop when it comes to flat earth debunking, not only you have managed to bring out fresh arguments against already debunked flat earth videos, which made them fun to watch even if I had already watched them for the 4th or 5th time, but also in my opinion, your arguments against the flat earth are the best and better researched and backed up arguments of any flat earth debunker I can think of. Excellent work!

"It is a disappointing marriage of egotism and willful ignorance." Well said, The RealTacCom.

You also don't ever see any flat earth snipers.

Myself and a colleague, both mining surveyors went into civil engineering when our pit shut. Even though we are both qualified mining surveyors we found this book invaluable in our new careers. Yes we definitely took into account the curvature of the earth when calculating surveys. These flat earthers are living in cloud cuckoo land!

I worked on a land surveying team in the 90s. Accuracy is everything. That’s why GPS could not be used directly, it was too fuzzy. Being 1cm off at one corner of a property line gets hugely magnified if the area being surveyed is large at all. Edit: Apparently GPS is used now in surveying, mea culpa.

You might also consider that VHF and UHF radio signals are often described as "line of sight" because the transmissions, unlike those of shortwave or HF, are not reflected back to earth by the ionosphere and even the most powerful signals go off into space when the earth curves away underneath. The radio horizon is somewhat greater than the visual horizon for technical reasons (antenna height, etc.), and there are things like tropospheric ducting and sporadic E propagation, but in general, the thumbnail rule is correct: line of sight. If the earth were flat, V/UHF signals could reach across the planet. They don't.

This isn't quite true, a friend of mine is a land surveyor and his coworker is a flat Earther. He factors in the roundness of the Earth in his daily work but still somehow thinks it's flat anyway.

As an ocean sailor, "Flat Earth Theory", is strictly a form of humor.

I am convinced that there are only 2 types of flat earthers: 1) Those who are are trolling us all and get their jollies from people losing their minds and spending all kinds of time and effort combatting them, and 2) Those who have a mental or emotional illness based in paranoia and/or delusions. I'm guessing category #1 represents 85%+.

One thing I've noticed about Flat Earth arguments is that the Flat Earthers fail to realize that "flat" and "level" are not the same thing. Flat means the surface is is plane. Level means that the surface is perpendicular to the force of gravity. Biiiiig difference when you get to a surface that's over a half a mile long. Jody, retired Civil Engineer

The curvature of the earth is taken into account when building long suspension bridges. The towers of the Verrazano bridge are 1⅝ inches (41.275 mm) farther between the tops than at the base. The curvature of the Earth needs to be taken into account because the project extends on a relatively long distance as well as upwards. The height of the towers is 693 ft (211 m), and they are 4,260 ft (1,298 m) apart. If the curvature of the Earth is not taken into account, then the two poles would not be straight towards to the center of Earth’s gravity, and the bridge will not be able to support itself properly. The cables would have to support some of the weight of the towers, as well as the load from the passing vehicles.

"Why there are no Flat Earth Surveyors" Simple. These people don't flunk pre/elementary school and later get a proper education.

I navigated ships in the Navy. Ships follow curved paths when crossing oceans because the Earth is curved. Now I'm a professional engineer. Of course that means I had to take classes in surveying. Of course surveyors take curvature into account.

This is basically what confused Lovecraft so much he kept going on about Non-Euclidian Geometry when describing his impossibly ancient civilisations. But Everything on the planet is built that way because we're not on a flat plane.

Telling flat earthers to take a course in surveying is like telling a sovereign citizen to go for a law degree. :)

Video game models have a similar issue. When you make a 3d model, and you want to texture it, you have to cut it up so that it can be laid flat. So that a flat image can be applied to it. It's an art of in it's self. You don't want your cuts to be visible, but you also don't want the texture to be stretched. laying a sphere flat will always be stretched and squished.

This channel is so good. Some of the most persuasive and most non-confrontational debunks I've ever seen on the platform. Probably among the best for actual deradicalization of flat earthers. I hope many of them watch and take your arguments to heart.

It’s because the earth isn’t flat.

I run a surveying business now but when I started surveying at 18 years old the first thing I learnt was levelling and the curvature of the earth. When traversing long distances we never take readings further than 120m-150m due to errors which then show up on the closed loop traverse results.

Books, eh? Hmm...🤔 When I was a kid (long before the internet and mobile phones were around) I spent hours in the local library, just reading. I'd lose track of time and get into trouble when I eventually wandered home, late for tea. (Actually, the librarian used to phone my parents to let them know where I was and that all was well, but I only found that out many years later.) It was wonderful, it was free, and it was usefully educational. I say 'usefully' because I knew that books were 'proper'. Every word I read had been through the old-fashioned process of being found fit for publication. Getting any book accepted by a recognised publisher was, and still is, a big deal. What I was reading had been proof-read and fact-checked and revised and edited and rewritten and re-edited by grown-ups. The publishing company's legal department would have checked every line for potential problems. The maths, physics, biology, chemistry and other scientific books and papers would have been peer-reviewed by ferociously hostile, critical authorities before being allowed to go to print. People today will roll their eyes (🙄) at the thought of going to a library, being quiet, and studying. They'll say that everything they want can be found online; Google is their God; a mobile phone has access to billions of books and articles and papers, so what's the point of going into a (yawn...) library? Well... the point is that uploading information to the internet is open to all and is not subject to the rigours of the editorial process. Frankly, anything goes. People make stuff up. People lie about their qualifications, their sources, and their data. That may not be a problem if you're just vanity-publishing your book of awful poetry on your own website. You don't care that your manuscript was rejected by 14 big-name publishers and 22 snooty literary agents who wouldn't even answer your letters; you're just happy to see your words in print. Sort of. But it IS a problem when you're broadcasting the kind of specious pseudo-scientific bilge beloved of cultists, God-botherers and conspiracy theorists. I suspect that Flat Earthers avoid libraries because the dusty old books - full of 'facts' - distress them. Yep. Much safer to lurk in a cellar, tinfoil hat in place, trawling the internet for tosh and seeking fresh converts. Besides, the 'facts' are all fake, yeah? Everyone's in on the conspiracy. EVERYONE. Sigh. No amount of evidence or proof will ever persuade these paranoid nutters that they're deluded and wrong. As with any faith-based undertaking, their beliefs are unshakeable because they're not based on reason or logic but on a desperate need to be taken seriously by their equally tragic peers. And the goalposts can be moved an infinite number of times to accommodate their crackpot theories.

The Great Trigonometric Survey of India was so accurate that not only did it show the Earth is curved, but how much that curvature (actually closer to an oblate spheroid) deviated from a perfect sphere. I live within driving distance of Pike's Peak in Colorado, USA, and I have done angle measurements of distant objects compared to the celestial horizon. All distant objects appear lower than they should if Earth were flat. While it's hard to see Earth's curvature if you expect it to be in the orientation of a steering wheel, it's easy to see if you look for it in the orientation of a bicycle wheel.

Of course, a FLERF will claim that ALL the surveyors have bought into the conspiracy 😞. I took a beginning survey course as part of my Engineering Geology degree. Since it was an introductory course, we were told we would not take into account the curvature of the earth as our survey distances were short - basically on campus. More advanced courses would take curvature into account, but we weren't training to be surveyors, we were just being introduced to survey concepts and how the instruments. work. That was 40 years ago and I still remember this course and how much I enjoyed being a nerd on campus surveying around the University. Since our campus was at the base of a mountain, we also discussed how some early surveys were wrong because of the use of plumb bobs, which were used to level early survey equipment, would be off a bit while surveying in mountainous areas due to gravity - yet another FLERF debunk. Say hi to Rusty!

A quick correction as someone who is in the Land Surveying profession, Transverse Mercator is not Mercator. It is almost the opposite, things get more distorted as you move east and west. It holds north and south distances along its central meridian as being equidistant.

Flat earthers want to completely disrespect science. This angers me.

Uh oh! Our secret’s out! I was a partner in a land surveying firm for 13 years in the state of Tennessee, USA. I started out working as a professional draftsman and instrument-man (I sat up and operated the theodolite). It’s true that land surveying is remarkably accurate. We typically aimed for a thousandth of an inch tolerance in our traverses and other measurements. It’s also true that while surveying the curvature of the Earth was not a major concern most of the time. The reason is, curvature would typically only come into play when we were surveying something like a large urban building complex requiring extreme accuracy in measure and layout or when surveying a very large plot of land (such as a farm of several hundred acres). Most land surveying (at least where I worked) amounts to relatively small plots of land, small enough so the Earth’s curvature doesn’t factor in that much. In those smaller surveys, if you’re reducing your traverse to horizontal and averaging any accumulated error throughout the traverse then the Earth’s curvature is taken care of in those calculations. Having said all that, I can attest that the Earth is most definitely, beyond any reasonable doubt, NOT FLAT. The Earth we live on, and the one I surveyed, is a big beautiful sphere! Or oblate spheroid to be more precise. It’s round. The Earth has been round for as long as people have walked it’s surface, sailed its oceans, flown through, and orbited above, its atmosphere. And it’ll likely remain round no matter how many misguided folks choose to believe it’s flat.

If surveyors get math wrong.... It costs the company millions if not BILLIONS and the project would have to be redone from the beginning. The shear accuracy we run on is insane and if no one calculated it right things get wasted and costs more money.

I don't tend to make fun of disabled people particularly those who are mentally challenged, however with flat earthlings I will make an exception and enjoy watching this.

I’m not so sure there are no flat earth surveyors. When I lived in Iowa, there were two surveying companies in town and I lived next-door to the chairman of the surveying department at the University. Chronically they would be cases where one of the companies would lay out the boundary lines and they would be wrong because they did not correct for the curvature of the Earth. My neighbor would get involved and would point out the flaws in that survey and then the other surveying company would be called in who would correctly lay out the boundaries. I wondered why this kept happening, but after watching your video I suspect that the people in the one surveying company may have been flat earthers. 😂

This is the "Chudley Building Construction Handbook" of surveying that I used during my BTEC in Construction I did back in 1999. These people could just rent a couple of levels/theodolites and test this for themselves by pointing them at each other. Provided you can level the devise then you are good to go.

I wrote the navigation system test plan for a USAF trainer. The system performance specified in the contract required that the system comprehend Earth's curvature. So while I can't personally confirm the curvature of the Earth, I can confidently say that the USAF trains pilots that the earth is an oblate spheroid.

Funny 'coincidence' that almost every comment from a flat earther is absolutely riddled with spelling and grammar mistakes.

You can't teach flatearther to survey. You need certain IQ level to understand surveying. They would just not get it.

I would suggest reading up on Everest (yes, the mountain is named after him). He was engaged to survey the Indian subcontinent for the British Empire in the 1800s. His measurements were remarkably accurate and we can still read his notebooks today. And you can quite literally calculate the curvature of the Earth from his measurements.

If a flat earther became a surveyor he would read that line about not normally needing to account for curve under 120m and would ensure all his tests were under that scale. Then he would cite how he's an expert. I've seen too many grifter flat earthers who will go WAY out of their way to make sure that the tests confirm their bias for their viewers. I've also seen them create a "margin of error" that is wide enough to accept R as a result so that they can say their test passed when it measured R instead of horizontal.

I was gonna be a surveyor, but I just couldn't do it. They wanted me to sign a 2000 page contract in blood. I could get over the pages being bound in human skin part, but what the hell do they need my blood for?

I was a surveyor for 4 years, and I was 10 years old once too. I can honestly say, I knew the earth was a sphere when I was 10 years old, way before I worked as a surveyor.

I'm in Australia and it's very obvious that it's a globe Earth, as I can see the path of the Sun everyday and the direction of rise and set. If you've spent time outdoors at night, you'll also notice the Southern Cross like a "24" hour clock hand during the night rotating about the Southern axial of rotation point. But there are still people in Australia that believe in a flat earth, they have no clue which direction is which either. This despite the path of the Sun being totally inverted compared to the flat earth model.

"maybe some flat earther should take a course in surveying" As if a flat earther would actually put any effort into doing research.. the last time someone did so they found out that there indeed a 15 degree per hour drift (thanks Bob, RIP)

Crazy how there aren't any surveyors who think the earth is flat 😂😂😂 I wonder why?

Iam an engineer planning roads over hundreds of km. I wish the earth were flat. Accounting for different koordinate systems, different relation ellipsoids etc. is a nightmare

Beside surveyors, there are no flattard sailors, airmen, snipers, artillery gunners an children that didn't skip physics in 6th grade.

I'm from Saskatchewan, Canada. The initial surveyors measured fields into sections which are 1 mile square and equal 640 acres. They had to add a correction line every 24 miles going north to correct for the earth's curvature. The correction is ~ 1 mile. The northbound roads all jig West by a mile every 24 miles going northward. Kind of proves a spherical earth.

During the Bikini Atoll nuclear tests, sensors intended to measure radiation energy levels from distances, failed to collect data because the military engineers who placed them failed to account for two things. Radiation travels in straight lines if not refracted, and the world is round. When they adjusted the heights the sensors were placed at to account for the curvature of the earth, they were able to collect the data they sought.

Flat earthers are the reason why shampoo has instructions

That seems to be what people who don't understand science don't understand. If it works, then it's correct. When there are 100 different independent ways to measure the same thing and they all agree, that counts as "working."

Disregarding the flat-earth V globe-earth aspect, these are always such educational videos. I'm a "globe-tard", but I still watch these because I come away with some new bit -- or bits -- of information that I didn't have.

I would enjoy the court case where a flat earth survey company is sued, then has to prove the earth is flat to the courts in an effort to explain why their measurements were so off

I've watched a few flerf debunking videos, and this is the first of yours I've seen. I love how you do it! It's very clear and easy to understand, also engaging in a way that keeps my attention. I need to look at your stuff some more. Great work!

As a chartered Civil Engineer I can confirm that we are part of a consp..... no wait Great video, and partially how I got into viewing how daft are flat earther videos. Years ago I stumbled into a discussion where one side was saying engineering drawings proved flat earth, and I felt compelled to jump in and point out it was in fact the opposite. The conversation (loons typing furiously in capital letters) soon turned to surveying and I used the vertical angle point you raise in your video. I was at Uni in the 90's and had a fresh off the press Third edition of Surveying for Engineers which was my companion for the first 2 years of my degree. I did a little surveying professionally, but mainly doing checks on site. At Uni I was taught the basics on a theodolite and progressed to NAl (New Automatic Level) and EDM (Electronic Distance Measure). When setting up stations for the first time we were asked that specific question why to stations set up 90 degrees to the horizontal had two different vertical angles to the level. You would be amazed at how little you need to move the instrument, about 10m, to pick up a difference on an EDM. Once I had pointed this out to the flefrs they saw the error of their ways and went on to have productive live....no wait :D PS Bit scary but this was 30 years ago so happy for any real surveyor to correct me :)

The one positive thing about flerfs is that I constantly learn more and more about interesting stuff like this because of how many ways people prove that the Earth absolutely cannot be flat.

My question for flat earthers is…explain sunsets and sun rises. Explain why I can watch the sun set from the ground, then go to the top of a tall building (grain elevator in this case) and watch the sunset all over again?

As a surveyor myself if an area is small we dont really account for curvature when the area gets over a certain size we account for curvature

9:38 It's worth pointing out that the Ordnance Survey was founded the year after the completion of the Anglo-French Survey (1784-1790) which literally measured the curvature of the Earth (with surveying equipment). The best bit is that the AFS published its data, calculations and conclusions, and that document is available online for free. That means anyone could theoretically refute it if they wanted. I seriously doubt any flat earther is going to attempt that, but you never know...

Oddly enough, I once had a lengthy conversation with a guy (he was using a pseudonym) with a flat earther who claimed to be a surveyor. He knew nothing about geodetic surveying, of course. He also claimed that he surveyed large sections of land and that it was evidence of flat earth. Of course, he could well have been lying. I have found that they tend to lie a lot. After all, it often is said: #GottaLieToFlerf

Try hitting something with an artillery piece 15 kilometers away with only 2 tries without considering the curve or the earth

Who you gonna believe: civil engineers, or guys with no credentials who do flat earth documentaries in tank tops?

I saw a graphic example of the curvature - decades ago, standing on the wharf at Omoka in Penrhyn lagoon in the northern Cook Islands, the tops of the coconut palms at Te Tautua the other side of the lagoon nine miles away are just peeking over the horizon. I did a back-of-the-envelope calculation of their height (you only need Pythagoras) - assuming R=4000 miles, they worked out at about 50 feet from memory. Later on we went across the lagoon in a boat and sure enough the rest of the trees and the village came into view. I didn't have a tape measure or a local volunteer to measure their height directly but but fifty feet looked about right - but then I would never have believed that anyone would seriously question the curvature of the earth in this century.

I was US Army. Every map I ever dealt with using the MGRS grid system has a different angle depending on where on the earth it is for. That angle, is the angle between Magnetic North and True and Polar North using The North Star and The North Pole for reference points. The closer to either the North or South Pole, the wider that angle gets.

This reminds me of the interaction in Kerbal space program. The runway for your aircraft is perfectly flat, meaning your craft will roll forward towards the center due to the way gravity is coded in that game. A similar thing would happen in real life with appropriate scaling.

So people whose job it is to measure the shape of the earth know what shape it is? Who would have guessed?

I have done civil engineering, I've worked on various construction projects from roads, structures to renewable projects through to the mining industry. I commented on one of SciMan Dan's video that briefly touched on this. We do account for curvature. On a some projects such as a small free standing structure it is nearly negligible but bridge construction and subsurface tunnels it would create a huge problem.

As I just started a career as a surveyer, I can totally confirm I made a bloodoath to 'the elite' regarding the real shape of our planet.

All the Flat Earth surveyors have fall off the edge never to return! 🤕
