Flat-Earthers are back: 'It’s almost like the beginning of a new religion'
“YouTube user TigerDan925 shocked his 26,000 followers recently by conceding a shocking point: Antarctica is a continent. It’s not, as he previously thought, an ice wall that encircles the flat disc of land and water we call earth.”

When I stand at the water's edge and look out over the ocean, how far away is the horizon?
“One of the funniest things about the ocean is the fact that its surface is curved. We tend to think about water forming large flat sheets, but the surface of a large body of water is not actually flat at all -- it follows the curvature of the Earth.”

This guy is an idiot!! Ships don't disappear because of the curve of the Earth. They disappear because the eye can only see so far due to the law of perception and the vanishing point. If you look out of a telescope, the ship will appear again. Ball debunk #1!!

Author 541 JayDub541 ( ago)
You really didn't debunk it though. If as is always said "go to beach and watch ship sail over horizon", with a vanishing point of vision or horizon at just 3 miles away you would not be able to see a ship sail over the curve, as with a sphere of 24901 miles around there is only 1 degree of curvature in 67.8 miles, meaning that you would not see a ship sailing over the curve in just 3 miles. this would have to happen due to something other than curvature. as far as the pictures it's noted that from nasa they are composite photoshopped images. Now for the shadows from two sticks, that could easily have been observed in the same manner if the sun is smaller in diameter and closer in proximity. As far as the moon goes it too is smaller in diameter and closer in proximity. The Tycho crater on the moon is only 50 miles in diameter yet from 238000 miles away this is observable with the naked eye. Scientists claim that observations that cannot be duplicated or explained are "psuedoscience" yet theoretical physics and all theoretical sciences would therefore also be psuedoscience due to the fact that nothing they state can be duplicated or even observed. The building block of modern science has never been explained as to what it is. Therefore using something that you cannot fully explain or understand as your foundation for everything else would thereby nullify all discoveries based on such false information.

this video proves nothing. go watch a boat disappear over the horizon, then pull you zoom camera out and watch as the whole boat comes back into view. the moon terminator is not caused by the earth and all this takes is a Google search to find. get ur facts straight.

Author Sami Neve ( ago)
what a stupid video. the earth can be flat and round but not a globe

Author Uriel Septim ( ago)
"Love you, neal"? Neal is a charlatan freemason.

1. As you observe a ship going out to sea, it SEEMS to disappear because of the vanishing point of your perspective. However, if you pull out a powerful zoom lense, the ship comes right back into view up to 50+ miles away. Only possible on a flat plane. Also, islands over 100 miles away have been zoomed in on at sea level, where there should be a curve of 6,273 feet, and lasers have been shot over the great lakes showing 0 curvature in large bodies of water or oceans hence, "sea LEVEL."

2. The earth being flat doesn't mean other celestial objects are flat. I don't believe the sun or moon to be flat like the earth, I think they're spheres. Does a basketball have to be flat because it's on a flat court? No.

3. Eclipses are mysteries to both cosmological explanations.

4. The shadows can also be explained by a close sun of 3 - 4,000 miles away with a diameter of 30 - 40 miles (orbiting the equator, fluctuating north/south for the seasons). This can be shown through basic trigonometry of the suns crepuscular rays.

5. Ball earthers don't trust science. True flat earthers are some of the most scientific people in the public I've met. The thing is there's a huge counter operation to discredit flat earth which is what the flat earth society is.

6. I've been in a "PLANE" at about 30,000 feet and still have observed no curvature. I've seen footage of weather balloons 120,000+ feet in the air without a fish eye lense proving the earth is STILL perfectly flat in all directions with the horizon ALWAYS meeting eye level. Impossible on a ball with a circumference of 24,860 miles averaging a curve of 8 inches per mile squared (0 observable rotation of earth also BTW). The horizon should seem to fall away with the 8" x ym2 theory, with the highest point of the earth directly below you. Instead the horizon holds its ground level and meets your eye.

7. Flat Earth Society = Flat earth psy-op.

8. 3:26 is a fake CGI image admittedly photoshopped by nasa (which means, "to deceive" in ancient hebrew btw) just like all the rest of them. There are 0 pictures of the whole earth from space.

9. 9/11 is obviously an inside job.

10. God help you.

Author George orwell ( ago)
911 was a inside job

Author Michael Montelin ( ago)
His first point was already proven false you can take a telescope and pull the ship back into focus after it disappears from the perception of the human eye. You can find videos of this on YouTube. Also a simple flight should prove that the earth is not round. Google this if you don't believe me but at 40,000 feet you can see 244 miles in any direction by looking out the window. If you divide 8000 which is approximately the diameter of the planet by 244 you get approximately 1/32 of the earths diameter. Meaning there should be curvature within those 244 miles in order to complete a sphere. There is not. Even at over 80,000 feet when you can see over 1000 miles in any direction you still cannot see curvature. That's 1/8 of the earths diameter. Once again you can check out videos from weather balloons and see this for yourself. I find it funny it's not until astronauts get into space that you can see the curvature. I've flown at over 40,000 feet several times on a clear day and never noticed any curvature. Why is that? I'm all for people proving the earth is round but when did we throw all logic and reason out the door just because some scientists told us the earth is round not flat. Oh and I'm sure someone is going to call me stupid. But the only stupidity is believing something you're told without actually looking into it. And I'm sorry but the points he made in this video have already been proven wrong. I would like to know why when you can see a good portion of the earth from such high altitude (minus going into space if there is such a thing) you cannot observe any curvature? please someone explain that to me and please do not use the we've been to space so we can see it from space argument because unless you've actually been to space that is not a relevant argument. I want to know why we can't observe curvature of the earth in our own atmosphere.

'Ball Earth' supporters can prove their theory easily if it's true. They never have. Just choose any 2 fixed points on Earth and tell us here in advance (so we can arrange its verifiable measurement) the accurate and exact distance between them. Include in your calculation the amount of supposed 'Earth curvature'. But you know what ? The ball earther CANNOT DO THIS. He never has. He never will. This ends his shell game. He is a fantasist. Flat Earth wins hands down. There is NO 'EARTH CURVATURE'.

I'm no flat earther but whenever I see "debunking" videos lump all 'conspiracy theories' together (especially with the flat earth garbage) I can't help but wonder if the producers of said video would have or have ever made a "this is why the government is not spying on citizens or collecting metadata" video.
Because there are conspiracies out there that we have been calling out for years which are no longer just theories. Unless of course you believe Wikileaks and Edward Snowden are just more 'conspiracy theories.'

Debunk this.... How did building 7, a 47 story building collapse at 5:20 that afternoon when it wasnt hit by an airplane. And if you say office fires then think again. Office fires or even aviation fuel doesnt burn hot enough to melt steal. And why did Larry Silversteen say that there has been such a terrible loss of life so were going to have to pull building 7. They even did a countdown and it fell at the speed of free fall just like controlled demolition. And if you say they wired it for demolition then I say it takes weeks to wire a building for demolition and its illegal to do so when it is occupied. Building 7 was occupied up to and including the day it fell.

ppl need to stop being jerks. someone who doesnt trust popular belief is not automatically retarded, maybe wrong or innocently ignorant. The explanations for round earth make sense but they are concepts that may have been hard to come by or fully understand. Its not like governments/authorities are always honest...I never was a flat earther but I sympathize with people that have a hard time trusting voices of complex things. Sure if someone is 100% confident in flat earth needs to take the time to really study it (or just have faith in "smarter people") but im sure there are alot of ppl that are not 100% either side and thats ok. It just means they too have an opinion but some patience and sincere thinking is all they need. Not insults.

According to his linkedin, Trace Dominguez has a BS in behavioral psychology, and a MS in Public communication. How is he an authority to explain the physics of round earth/ flat earth, with a clear bias and mocking undertone?

I'm not arguing for either side here, I'm just saying don't take people like this guy's word for it. If you're truly interested in finding out if the earth is flat or round, study physics, math, and other relevant science and use the scientific method to test the information you are presented with. It's also important, and sometimes difficult, to design tests that will actually test what you are trying to measure/find out. Of course, 99.999% of people are not interested in using their minds to actually test the validity of the round earth model, and yet they will fiercely defend it as if they personally know it without doubt. I can honestly say I do not know, and that both "sides" have compelling arguments.

This bloke is embarrassing. The stupidist thing he says is claiming he knows all FEers don't trust science. Meanwhile, the reality is an unknown percentage of folks become FEers due to conducting their own scientific experiements in stead of blindly believing what the "experts" say.

I think this vid is good for non thinkers who, having been indoctrinated, conditioned in school, then through mass media, already believe the earth is spherical and see no need to find out for themelves.

Author Mike Ross ( ago)
Also note .... the formula for the earths curve is believed by many to be 7.99 inches per mile squared. This means that at 4000 miles out from line of sight the surface is 2,020 miles down. WRONG it is 4000 miles down. This seems to work for short distances when compared to a CAD diagram but falls apart at large distances so it is not accurate.
Other sites and videos dont mention the squaring of distance so it descibes a slope not a circle.

Author Mike Ross ( ago)
I had to stop at 45 sec in. Any zoom lens will bring the disappearing ship back into view as it will anything that is beyond the horizon. Science says this illusion is caused by light bending ( refraction ) Retarded fucks like Infamous Matt dont know this because people like that are to busy trying to insult others that they cant find a way to debate this kind of evidence because they dont even know about this light refraction optical illusion argument. now that he does he will accept it as fact.

If the Earth is flat there would be a beginning and end. The ocean would just run off the wnd. or if it ended with land being the furtherest part you could just jump off.

There is a rotation of the stars that you NAsshole con artists are bullying Americans into believing is being seen from a "giant ball," an obvious lie. The stars all spin on a fixed axis point, you cannot deny that! This would be impossible on a "giant globe." The stars and with their constellations for centuries have been used to navigate the seas, as they rotate in a fixed position, that would be impossible on your ball earth model, therefor you ARE a con artist.

Go and speak to a pilot. As him (or her) whether (on a long-distance flight) the pilot has to continually steer the nose of the plane downward, which is what pilots would have to do to compensate for the curve of "globe". Isn't it right? You agree that's what pilots would have to do, right? And of course, you know an argument like "gravity automatically pulls the plane's nose downward" is ludicrous. Why would gravity be so selective?
And about gravity. So-called gravity is strong enough to make all the water of the oceans cling to a sphere, that's not only spinning around its own axis, but also hurtling through space at incredible speeds, yet a little lady bug is able to fly off with no effort whatsoever. Does that make sense?
And of course, planes flying westward would actually be flying at 1000 miles per hour (speed of earth's spin) plus their own speed. Whereas planes flying in opposite direction would have to travel at above speed - just to remain stationery!! And please, don't tell me the earth's atmosphere spins with the earth. How could it possibly? And even if it did (let's suspend all common sense for a moment) why would it have any effect on things like planes. Once again, is gravity really that selective?? I don't think so.
Go ahead, sad little sheep. Try and disprove those.

But wait. Your so-called celebrity scientist, neil degrasse Tyson, said the earth is not a perfect sphere. He called it pear-shaped quote unquote. In fact, astronomy in general teaches this.

Could you imagine how hard that would be? Do your own research. I would really study the suppose curvature of the earth and gravity. What is gravity? Tell me what it is. You can't, because you don't know. You don't know, because no one knows. No one knows, because it doesn't exist...

The Danyang-Kunshan bridge is 102.4 MILES long. It is over the ocean and should have a curvature drop of 6,990.5 ft. but it is flat and you can see the whole thing. Refraction only adds 0.232 miles to your view over the 3 mile horizon, (for you globers that would be 3.233 miles by GLOBE math). Engineers who build these long bridges, railroads, tunnels, cable lines, pipelines, and highways do not have to calculate for downward curvature because there is none. Repeating public school education/indoctrination doesn't prove anything. Globe believers, apply your math to real places in the real world. Find the appropriate curvature that fits globe math and this will all go away. No one can find it. You think you wouldn't be able to see almost 7,000ft of curvature drop in a bridge over water? Wow and flat earthers are being called dumb. I am not convinced of everything in current flat earth models, but what I know is that globe math isn't the truth. This can be tested by people who aren't lazy. Maybe the earth is 4 times bigger than what they have told us. I did the math on that too. There is no curvature on earth that would support a globe at 100,000 miles in circumference. So where is the curve for a 25,000 mile circumference earth? Ask real questions. Give real answers. Stop repeating public education/indoctrination dribble. Find the curvature drop that fits globe math, anywhere on earth (get off your rears and go outside), and this will all go away. Do the math. I am a flat earther because I tried to debunk it with globe math and a desire to believe in space. There is no curvature. Prove it for yourself. That is how it always begins.
