So gravity is the theory that we are all being pushed towards the Earth's center. In the globe model this doesn't even make sense, because if that were the case we'd all be sucked into the Atlantic ocean, specifically right here
In the flat model, of course, this would mean we'd all be getting sucked into the North Pole, which is a more logical position, but still, it's not the case.
What's actually going on is different. We are technically being pushed, but not towards the North Pole, and certainly not by Isaac Newton (how did gravity work before he invented it? Globers never have an explanation). We are being pushed down by God, by what I like to call God forces, or G-Forces.
You see, humans once tried building a tower that would be so massive it could reach all the way into heaven. God obviously couldn't allow this, so he smashed the building and changed all our languages. But most importantly, he introduced the G-force, which is constantly pushing things into the ground, so we can't build towers like that anymore.
Birds are immune because they are the holy spirit, and buildings can still be made a few stories up, but that's it. Space travel, skyscrapers, and airplanes shouldn't be possible, because the G-forces will always be too intense for them to get that high. This leads us to believe that they are actually holograms, similar to the moon, meant to confuse you. If you've ever been in a skyscraper or an airplane, you were really just in a 5 story building with intricate optical illusions outside the windows. The same goes for airplanes, which are really just busses and boats.
If the earth is flat, then how do you explain the shock documentary "Journey to the Center of the Earth"? You say you love science yet you immediately dismiss this masterpiece of investigative science! You're a hypocrite!
