I do not think that word means what you think it means.
Here, have a video:
(The actual, irrefutable [!] proof is at 2:38 in the video.)
Those who have been around here for a while may remember my take on the flat earth theory, both the book Flat Earth and my own musings about the conjunction of Venus and Jupiter two years ago. I mean, bless they hearts.
To recap for those of you too lazy to watch this nice man’s video:
Here we see the set up: the god-fearing flat earth Person, standing on the Actual Earth, with his Globe* and his Airplane.
If you fly a plane from the north pole to the south pole, he says, look what happens. First…
… you have to start tilting your Airplane down in order to keep your plane level with the Earth. LEVEL WITH THE EARTH, KENNETH! This continues without let until…
…you are forced to fly your Airplane upside down before you can even land. This is clearly unpossible, and therefore it is irrefutable proof that the earth cannot be a sphere.
Okay. Let’s rewind the tape and insert a play by play here.
First we start at the north pole.
Pay attention to the little arrows. The little blue one shows the tiny Airplane in relation to the Globe*. The longer green one shows the Airplane in relation to the Actual Earth, which is where our irrefutable Person is, in fact, actually standing. The blue and green lines are in agreement about which way is up and which way is down.
… something seems to be happening here…
Hm. The blue and green lines are no longer in agreement about which way is up and which way is down. In fact, they are diametrically opposed. So why is our Person so convinced that the Airplane must be upside down if it flies to the south pole? Let’s remove the Globe* from the picture.
Why, look, he’s right! The Airplane is upside down! In relation to the Actual Earth, it is in fact, irrefutably, upside down.
But that’s not what is happening in real life, is it? Let’s zoom in on his model and change it into the Actual Earth:
Oh. The Airplane, in circumnavigating the Actual Earth, would find itself rightside up the entire trip, even when it passes over our now-Australian Person. Hm.
Let me be very clear: my little demonstration here did not in any way prove that the Actual Earth is a sphere. But it sure as shootin’ refuted Mr. Hall’s simplest, irrefutable proof that it isn’t.
In other words, this is not the proof you’re looking for, Kenneth.
