this is an actual flatearther Let me prove it Do you actually believe the Earth is flat Yes that's true But by the end of this video that may not be true anymore Because we've planned the most elaborate large scale and extensive experiment to prove the Earth is round without a shadow of a doubt Then we're going to lie detect him again at the end of the day to see if it changed his mind Because it is hard to prove that the Earth is round from the ground It is I mean even if it was flat there's hills and mountains and lots of curvy parts The only way to see the Earth's natural state is to go to the water You've never been to the ocean before right I haven't been to the ocean before so this is a sight to see I will admit it looks a little bit flat I'm not even going to lie There's a way we can test that If you were to take a boat out to the horizon we could agree that it would eventually disappear right Yeah We won't be able to see it Like the boats in Japan we cannot see from this coast There's two reasons that the boat might disappear One it could just disappear and slowly but surely vanish cuz it's too far away Or maybe it's getting hidden behind the Earth's curvature And in that case the curvature would actually start to obstruct the view of the boat so that it would disappear bottom first and then the middle would disappear and then the top would disappear So if we were to see that it would be very strong evidence of a round earth You could say if we saw that that would be the case But I don't think that's what we're going to see We kind of just going to see it get further and further away until we can't see it anymore But you would need a very tall boat to do that which is exactly what we have And I stuck my friends on it Ew the poop deck is stinky Ew Boys can you wave at us real quick Hey Hi Jack Hi Seb These are my friends Colin and Josh And this is Captain Matt Have you ever done anything like this before No I First time so I've been out here but not uh on a mission like this We've actually got a bunch of telescopes over here that are recording and that we can look through to make sure that we can see the boat the entire time Before we even get started the audience is probably wondering how you actually became a flatearther I think my process into becoming a flatearther is just like being curious being open uh to other ideas even if they do sound crazy I'm not going to shoot them down immediately I will admit that like I haven't gone a lot into the signs Growing up in Omaha I don't know I didn't really travel a lot and so that's kind of my looking left right up and down and kind of seeing that I don't see a curb Guys we are like really getting off the coast right now I would say we're still only about like 500 ft or so We just keep it like in this on this course Josh say y I look like Mickey Mouse Dude wait These waves are huge You know what else is huge This actually isn't my first experiment with Seb We tried taking a weather balloon into space and live streaming what the camera on the balloon saw into a VR headset that Seb wore on the ground a couple of years ago I didn't see any curve in that video and so just like reinforced the idea that um the earth could be flat We interviewed some other flat earthers as well to potentially be in this video The earth is flat I believe it's flat The earth is is a a flat stationary plane But none of them seemed as open as Sebett to having their mind changed I would open myself to that opportunity of being proven wrong He really is the world's chillest flatearther How's everything going for you guys It's great We're about to eat lunch Amazing All right see you guys Thank you Okay I got Lunchly Lunchly is that all you pack No no no no I got prime too Don't worry See had previously told me over the phone that if we were going to do this one thing that would really convince him is if the boat disappearing behind the horizon perfectly lined up with the math of exactly how far it should have to go if the earth was round for it to disappear I actually did do the math for you so that you would know based on the curvature of the earth what people are saying is the curvature of the earth how far away that the boat would have to get So do you remember the Pythagorean theorem A little bit A little bit The Pythagorean theorem is something we all learned in 8th grade but it's something that we can apply when thinking about horizon lines A^2 + B²= C² So this circle is the Earth if the Earth was round That's the center This would be us And this H is for height So this would be 6 ft off the ground cuz this is approximately 6 ft above sea level So that's roughly 6 ft This D is how far away we can see This is the horizon Okay This is R the radius of the Earth R the radius of the Earth plus our height and D the distance That makes a right triangle Does that make sense so far I'm following So then if you just plug in all the numbers the distance equals out to 15,837.67 ft or that converts to 3.0 miles So if you look it up most people will say when you're standing on the beach you can see about 3 miles to the horizon And that's based on this map So 3.0 miles away is the end of where we can see the ocean So at 3 m the boat will be on that line The boat will be sticking up like this So you'll still be able to see it Now how much farther does it have to go before it disappears completely behind the horizon The cabin part of the sailboat comes up exactly 5 1/2 ft off the water So at 3.0 mi it will still be fully visible It's only after this point that the horizon line will start covering the bottom of it You plug in all the numbers again and in this case you get 15,163.42 ft or 2.87 mi So over the next 2.87 mi it should disappear bottom first until at the end of the 2.87 mi the whole cabin of the boat will be gone So in total 3.0 plus 2.87 mi is a total of 5.87 87 miles out that the boat has to go for the entire cabin to fully disappear in the lens of the telescope which is exactly how far out Captain Matt is heading to How's everything going Is it all going well Yeah we're making good decent progress How far out are you guys going Like what point into the ocean are you guys going How many miles away 5.87 That's That's how far we're going Straight off the beach 5.87 guys 5.87 Is that them I think that's them Josh has got something to say All right So if the bottom of the boat disappears then guess what The earth is not flat And if the bottom of the boat doesn't disappear the earth is flat Wait is that good Are you sure the earth is not flat I'm pretty sure the earth is not flat Dude tell me that was the funniest thing you've ever heard in your life Yeah we probably shouldn't annoy Captain Matt too much Let's let him lock in It's also at this point I should probably tell you about the second part of the experiment Cuz if the boat disappears bottom first that's one thing But it would be even crazier if we could increase our height get a little higher and then see the bottom of the boat again because we're seeing over the Earth's curvature and then see the horizon line move further back which is why we have this building So we've rented out the room on the top right floor Once the bottom of the boat is gone behind the horizon we're going to call them and tell them to stop moving the boat completely And then we're going to go up to the top floor of the building and look out at the boat again with the telescope And from the elevated height we should be able to see over the curvature of the Earth and see the entirety of the boat again Seb we've spent so much money on this video Do you think people should subscribe Uh yeah Jack's great And if you subscribe this year your name will literally get sent into space Some people like Seb here maybe don't believe in that possibility However you should subscribe because your name will literally be sent into space using radio waves and aliens can find out about you So if you're interested in that you should hit that subscribe button See is definitely an interesting guy I've never met a flat-earther like him I don't really know why he believes the earth is flat Everything is about like Antarctica I think it is fairly fishy that like people aren't allowed to kind of just like go there randomly and stuff like that I feel like holding a lot of stuff back The United Nations logo kind of being basically what this is If it were kind of Yeah behind like a government conspiracy sort of a thing it could be something that like they're aware of I had to make sure he thought that maybe there was a chance he was right if there was any way I was going to be able to change his mind Here Josh is calling Josh is calling You keep looking Yo what's up buddy We're 3 miles out 3 mi out Okay it looks like you guys are right on the horizon which is exactly what the map predicted Oh any further out either you're going to start disappearing just in general or you'll start disappearing bottom first This is the moment of truth So this was where the boat should start disappearing behind the horizon But after being so open to the idea of the earth being flat it was at this moment that I started to get scared I feel like the bottom is starting to disappear a little bit I'm not even going to lie but I I don't want to have confirmation bias here You tell me what you see It does look like it's on top of whatever I guess the horizon and stuff but I can still see a lot of the boat This is This is intense I'm nervous I don't want my beliefs of the earth to be questioned you know But if they are they are You know what I mean I mean I'm ready to change my mind Jack did you run the math right on this Yeah we ran the math right multiple times I promise Just making sure Listen I know the Earth is round obviously but I was anxious Why wasn't the bottom of the boat disappearing yet We made it past 3 miles But then Josh told us this on the phone Hello Josh I don't know What It's good Can I put you on I'm putting you on speaker Wait wait Don't put him on speaker Can I talk to him Oh what Oh I got to save the numbers man I want to talk to him I want to talk to him I want to talk to him It is what it is Fine Put him on speaker I don't care No no no It's okay It's okay It's okay You're on speaker All right What's up everyone Hi We are um we're so we were we were tacking towards the north right now so we haven't made as much progress uh away from the coast uh on this most recent turn but we're about to turn and really make progress away from the coast And then we'll probably be around the point in like you know like 30 minutes or or something like that We're still not there yet Okay You're not there yet Okay Cuz I was getting nervous cuz you guys haven't really disappeared the bottom yet Y'all are using codes I was getting so nervous Now Seb thought maybe we were deceiving him but I just had to have faith in our experiment We knew it was going to work The Earth is round But this is when I came up with an idea for how we were going to make sure Seb trusted us When the lie detector guy comes back to my house later not only will we ask him if he changed his mind you can put Josh and Colin in the lie detector and then you can test them and be like "Were you actually going 5.87 eight seven miles out You can also interrogate me and Bella and anybody else here who you want to ask questions to to make sure that we weren't deceiving you at any point during the day Then we'll see if you changed your mind Right I really want Seb to trust us So hopefully that makes him feel better That's also why we've got two telescopes here We've got the optical telescope and we've got this one the Sea Star Telescope Shout out to ZWO for gifting us this and for the support on the video We've got that connected to the phone and that's how you guys are able to see it But I know you trust this telescope more because there's no way I could possibly digitally alter it right Yeah But this telescope works actually so well It's honestly very amazing how I'm able to just connect it to this app and then sort of joystick it around throughout the video See it was definitely skeptical Just another great reason I'm glad he's going to be able to lie detect us at the end too I need him to trust us What do you think they're doing right now We're We're almost to 5.87 miles And again I don't know what's going on over there I don't know what they're thinking I don't see that like edge go away like at all That dude that's like cuz it's consistently above water Do you know how much farther out they have to go I just had to have faith in science The boat was starting to wobble up and down behind the horizon but Seb still wasn't convinced They're saying they're almost at the point Come That's disappeared Not yet That's disappeared Oscillating and stuff Dude there's no cabin I'm going to be totally honest with you I haven't seen the bottom of the boat in a long time I'm going to just be honest but let Yeah the cabin is being more and more difficult to see but I don't know I'm interested in seeing like I guess with more zoom options Where's the binoculars They They'll call us They'll call us when they're at the point Yeah Yeah it's gone Yeah it's gone It's gone See come look Come look I mean there's like an inch left cuz they're not at the point yet but take a look I only see sail What do you see I don't see the cabin I only see sail We made it We made it guys 5.87 miles Exactly See those buildings over there Yeah This is it Those buildings are exactly 5.87 miles away I'm going to give Jack and Seb a call Hello Hello Yeah What's up We are at the point of contact Okay In Seb what do you see I can see the sail I don't see a cabin The cabin has totally disappeared for us But now we're going to go to the top floor and we're going to see if we can see it again We are going to We are So we were still moving We're the right distance We're still like moving parallel with the coast but we are stopping right now You're just going to stay the same distance Same exact distance We're going to same stay the same distance Okay What are you thinking right now Yeah I don't know Yeah I don't see a sail or I don't see a cabin You don't see a cabin All right let's go up and see if we can see over the curve of the Earth I'm very curious to see what we see up here I am too Um I guess yeah there is two parts to the equation [Music] All righty we made it Oh my Why are you nervous Uh I guess I just don't want to see something that um don't want to see I guess But uh hard to tell the difference between anything But um but like it is it's a different view I could see the boat Yeah me too All right let's get this thing set up [Music] Um no I don't know Jeez that's something else It's a different view Looks like it kind of appeared back in front of the horizon I mean it's really exciting when you can discover things for yourself you know It's my first real polygraph test This is This is really cool Not even going to lie my hands are already really sweaty Before we ask him the final question for you guys to see We want to make sure that he knows we didn't lie to him at all today So let's see And while Seb is grilling us I want to tell you about something Did you lose faith in your experiment at any point during our test Oh no No True That was honestly a close one Doing this boat demonstration wasn't cheap but thanks to Delete Me the sponsor of this video it was possible And with Delete Me it's also possible for you to get your data out of hackers hands for them to stalk and harass you with Did you exaggerate anything that we saw today to provide for a more satisfactory result in any way No True See I once made a video where I called a hundred celebrities to see who picked up and warned them that their numbers were leaked online because this is an issue I actually care about Here's me telling Mark Cuban Hi I'm just calling to let you know that your number is leaked online I appreciate it That was actually him that picked up And whether he wanted to admit it or not he should have been scared Did that boat stop at 5.87 miles away from shore Yes Yes True True It was so easy to find these celebrities numbers on sketchy websites and just give them a call If any of them were using Delete Me though they wouldn't have had to worry as much about it because Delete Me pulls your number off of hundreds of these sites keeping your data safe from bad people that can find it from these data brokers There was a good 20 minute stretch where we thought that y'all were moving further and further away but the boat did not appear to change height in any way A few moments later we got a phone call from you letting us know that you weren't going further away but instead further north We are tacking towards the north right now So the size of the boat wouldn't change So we haven't made as much progress uh away from the coast Were you coded in any way to call and suggest that the boat wasn't moving any further away No No definitely not True True So scan this QR code or go to joindeme.com/gordon Use

point that none of us have lied to you Yes True At this point Seb trusted us that there were no secret codes and nothing deceptive about the day Did you come in expecting your mind to change No True Were you expecting us to deceive you in any way No Why Were you surprised with the results Yes True At this point in time would you say that you now believe that the Earth is round Yes True It was a pleasure doing business with you Give him the flat earth Rip it up Rip it up Rip it up It's over We're done with it Rip it up Let's go I guess I'm now ready to go ahead and land on the uh not Oh my
