The earth is flat
Debate Rounds (5)
Note: I'm not of the belief that the earth is flat. The reason behind this debate is to come to the bottom of a specific issue that I came across recently: there is no earth curvature upon naked eye observation of the horizon, only when using fisheye (GoPro) type cameras that create illusions, f.ex., Felix's camera created a great curvature at height of only 3-4 km.
I myself witnessed this view of a flat horizon while travelling with an airplane at 10,000 meters. I took some pictures of that and now I'm still in confusion.
This I find very puzzling and I can not find peace of mind until I receive a scientific explanation of this very specific and unexpected issue that any and every person can confirm by observing the horizon from an airplane or viewing no-fisheye onboard cameras on rockets and weather balloons.
Here I will provide a video of the phenomena, note that I am in no way supporting the uploader of this video, I use it merely for illustration: https://www.youtube.com...
The curvature of the earth, according to basic mathematical calculations, should be seen slightly at low altitudes of one or two kilometers, and seen clearly at passenger airplane height or more.
I have given my proof in the first post. Reply.
Note that I am Against that earth is flat.
You may start your case
I have. Why don't you read my first post?
My opponents have talked about how he himself witnessed a view of a flat horizon on an airplane at 10,000 meters. This extraordinary claim needs much extraordinary evidence, and I request you upload these pictures in the next round. In order for this, we will have to upload the pictures of these claims and if they fail to do so, that makes their claim false.
Today there is a big reason to why the earth is round: It all comes down to gravity.
It is basic knowledge that the earth is round because of the gravity, which is explained more in the next paragraph.
C2)Understanding the concept of scientific research
 Two features of Earth that determine its shape are mass and gravity. These features are, in fact, interrelated. Mass attracts other mass, resulting in the force we call gravity. Smaller objects, such as a car or a house, have tiny gravitational forces. The amount of mass throughout Earth, however, is huge and really adds up. As Earth's mass added up from all this matter and gravitational forces increased, the matter attempted to take the most efficient shape possible: a sphere. If Earth was a cube, its corners would be farther away from its center than other points. Because gravity acts equally on everything, the corners would need to be pulled closer to the centre. Now that we have access to space, the easiest way to prove the Earth is spherical is to leave it and view it from a distance. Astronauts and space probes have done just that. Every picture of Earth ever taken shows only a circular shape, and the only geometric solid which looks like a circle from any direction is a sphere.
I will right more in the next round for I have not much character remaining
Here is the picture, and I accept everything you have said in your latest post about gravity etc.
Thank you for your picture. I will like to present my piece of evidence in a picture too from this website:
Lets look at it from a perspective: Lets take the ocean as an example
If earth was supposedly flat, these boats have a potential of falling off once they reach the end of the "flat surface".
However, because earth is round and the gravity within the sphere is pulling us towards the centre it makes more sense that these boats will not fall off the surface, moreover fall off of earth with gravity. Its like a rubber band. If you pull the opposite end of the band, it comes back to you after you let go. If we jump, we are pulled back onto the ground from gravity.
There is no fancy dancy explanation for this; its simply straight forward. Gravity is the real truth on why our earth has to be round.
Every object pulls towards its centre. A flat surface has no centre. Therefore, it brings to the conclusion that our earth is a sphere.
My opponents only have pictures that back up their case. However, these pictures may not be as reliable as common knowledge. We all know gravity, unless you skipped 3rd Grade. Yes, I agree that in this picture, it is straight grounds. But the earth isn't necessarily perfectly curved. If you draw a big circle, and measure 5 mm of the surface, it is somewhat straight but a little curved. Our world is big, and we can't rely on the reason why there is "no curve". There is, but we can't see it because earth is big and the airplane you were riding on is smaller than a hair on earth. and with those measurements we can't prove through pictures, as they are inaccurate in our stances of how we see the earth and why we can't see a curve.
I agree with you on everything, except that the earth is a sphere because of the picture you posted. (1) it's clearly computer animated (2) fisheye lenses can create that effect. Note, the fact that I disagree does not mean I believe the spherical earth is wrong, I only say that this is not good evidence.
He has only disagreed that the earth is a sphere. But if my opponents have already agreed with my arguments which is mainly that gravity makes it a sphere, this therefore makes this claim false.
They said that 1)It is clearly computer animated and 2)fish eye lenses can create the effect. This of course needs to be proven by pro but because this is the final round, I will just provide you another picture.-> http://i.stack.imgur.com... This picture shows that the reason why we can't see things that keep on disappearing from far is due to the round curvature of our world.
My opponents have not bothered to reconstruct nor refute my arguments except for my evidence, nor provided any real arguments except with the explanation from his picture and that he is "puzzled" by these. His side clearly falls because he conceded with my arguments and had weak arguments. He has not bothered to defend his side.
It is straight forward that the earth is round from gravity. There is no real explanation that earth is flat. All boats would be falling off by now if they reached towards the end.
Good debate. Apology for wasting some rounds, I was a bit confused in the beginning
