EarthIsNotFlat

I'm 100% agree with you. About the sound effects yes I'm familiar with that: https://www.youtube.com/watch?v=ggIzq8JUK44 https://www.youtube.com/watch?v=UO3N_PRIgX0 As I said in my opening post someone in another YouTube channel noticed that, someone else also noticed that when you see the helicopter from the telescope side you see it's Left side, but when they show the helicopter from close on the other side of the lake you see that it's Right side is pointing to the telescope... There is a logo on the bottom left of the video says: "Discovery Channel", also the description of the video says: "Discovery Channel full episode: https://www.youtube.com/watch?v=zgZgoWfZb6c " But when I click it I get: "Video unavailable". I'm not barking at anyone, try to be more polite. YouTube is not a formal scientific channel but this clip was taken from Discovery Channel. Yes I know that it's "Ad hominem" it was a typing mistake. For the last time I'm not a flat earther, if you don't believe me it's not my problem. The problem with this rocket videos is that usually (and I don't know why, anyone?) they use a fisheye camera so everything it picture looks round. Here are two print screens from your video, see how you see the same curvature when it's only a few meters from ground:

I'm not a flat earther, and what you are doing is called Ed Hominem (a strategy where the speaker attacks the person making an argument rather than attacking the substance of the argument itself). Doesn't it bother you that people on a formal scientific channel have to use fakery in order to support their scientific claims? It's still important, check this: https://www.forbes.com/sites/trevornace/2018/04/04/only-two-thirds-of-american-millennials-believe-the-earth-is-round/?sh=602deff27ec6 "Only Two-Thirds Of American Millennials Believe The Earth Is Round".

These are exactly the same birds, did you see the animation that I made? I'm toggling between 2 frames (one at 6:44 and the second at 7:42) and you can see that these are exactly the same birds, and also exactly the same waves pattern in the lake. Maybe you will see the animation better if you'll see it in it's original size, here: https://i.ibb.co/Qm6C5q0/Helicopter2.gif No way that two frames that were taken at different times has exactly the same waves pattern and 3 birds at exactly the same spot. You can check it yourself if you will open the video in 2 separate tabs on your browser, pause it on the first tab at 6:44, and pause it on the second tab at about 7:42. Now you can watch it Frame By Frame using the following keys on your keyboard: https://i.ibb.co/jbjhdMx/Frame-By-Frame.jpg You will see that the birds have the exact same pattern during all their flight from left to right, and as I said also the waves in the lake are exactly the same. The only different is that one frame has a helicopter and the other one hasn't. By the way I saw that Discovery Channel have deleted this video from their YouTube channel... maybe it says something. See my response to Eise. 1. The experiment in this video is trying to prove that the lake is curved because the earth is round... 2. 3. It has nothing to do with optics, see my reply to Eise. I don't know if you aware of this but there is a large and very loud group of people especially in the US, who claim that the world is flat. Someone have to fight against stupid conspiracy theories like that.

So you think that this experiment is fake?

Sorry my mistake, what I meant to say is that although the lake looks flat, it is curved because it's part of a round world. So when the helicopter is about to land on the other side of the lake the water are hiding it. If the earth was flat, the lake was flat also and we would be able to see the helicopter landing on the other side. But the main issue in my post is how can it be that two supposedly different times in the video has exactly the same background including the 3 birds that you see there? How do you explain this if this video is real?

Hi, There is a YouTube video that suppose to show a scientific experiment with a helicopter that proves that the earth is not flat. The experiment shows that the helicopter is vanish when it goes under the horizon which is something that cannot occur on the flat earth: https://www.youtube.com/watch?v=QVa2UmgdTM4 It looks very impressive, but someone in another YouTube channel noticed something very strange... in two different parts of this video you see the helicopter once when it is under the horizon, and once when its above it, but the frame and the background is exactly the same! Including the birds that are flying there! Now it's very hard for me to think that this video is fake, or that they cheated. Can you please look at the frames, and tell me if you can think of any reasonable explanation for that? Check this out: What do you think? Is this cheating?
