The Bottomless Earth

George Mayer: "Another flat earther bites the bust. No evidence for a flat earth."

Let's test that claim..

Me: "Which model has no bottom? A sphere model or a flat model? I look at the moon and I can see the top of it and the bottom of it. All three dimensional objects have bottoms to go with their tops. That's how we can find the center: it's in between the top and bottom. How do you find a center of a sphere that only has a top?  I would see my flat earth begin to curve the further I got from the surface and would eventually see it curve upon itself. It’s never an actual sphere. It’s only perceived as one from an outside observer that isn’t an experiencer (all of which cannot leave the top/center). A world can’t have a surface where it disappears. Worlds only work where you never run out of surface no matter how far you travel. The only way for this to be accomplished is to give it the mathematical definitions that prevent it from having ends/borders on the map. Euclid shows us how to make a straight line with no beginning or ending. It’s a circle with an infinite radius. What can be done with a line can also be done with a 2D plane."

Laurent Jade: "Take a ball and put it on the ground. It has a top and a bottom. Now take the ball and turn it any which way, and put it on the ground again. It now again has a top and a bottom, but they are DIFFERENT. "

Me: "I never said the bottom can't be different locations of the earth at any one time, only that the bottom is always present. Where is the earth's bottom presently?"

Laurent Jade: "Bottom... to who? Everyone on Earth is standing on top of the Earth at the same time. To someone in Australia, it's me, in Québec, who's on the bottom."

Me: "Exactly. It can't be a sphere. On a sphere, there is always a bottom, regardless of what part of that sphere happens to be the bottom."

Laurent Jade:  "Okay then. Answer my question: Which part of a die is the top part? The 2? The 6? The 5?m at the time."

Me: "It can be any side but there will always be a side that is 'bottom' regardless of which side it happens to be."

Laurent Jade: "So you're saying the bottom part of a die is purely relative?"

Me: "The bottom relative to an observer would be above the observer if the observer was on the bottom of the earth. You said there is no observer to confirm such a bottom exists."

Laurent Jade: "Australia could just as well be the top of the Earth. It's just in the way we represent it. Take a globe off it's base, spin it 180 degrees and put it back on its base, so the Antarctica is on top. It's still a valid map and a valid representation of the globe."

Me: "What you're trying to argue is that all sides of a die can be the top all at the same time which isn't true. Only one side can be the top and one side will always be on the bottom. If it isn't true for a die, it isn't true for a sphere, either."
