question 1 Q: If the world really was flat... what would gravity look like on earth? would we all be walking adds for V8? (Kevin, CA) A: No, we would not all be like walking ads for V8. We are all so small compared to the earth that our posture is not affected by the curve in the earth. If the earth was actually perfectly flat, they you would walk straight up. Keep in mind that the one sided flat earth is impossible. The earth would be three dimensional, So, for the sake of discussion, lets assume that only one side has water, air, trees, and all of that, which is unlikely. So, the earth is really some tpye of polyhedren instead of a sphere. All matter has gravity. Even you exert a gravitational field. Of course, the force of the pull is proportional to the mass of the matter, hence the reason that object don't fly in your direction. If the earth is "flat", the gravitational pull would depend on how deep the earth is. Keep this in mind though, when you get to the edge, you won't "fall off" as many in the 14th century believed. The gravitational pull would still be strong, and you would be pulled to the side of the earth. In theory, you could walk down the side and then walk on the bottom, since the gravity would keep you in. Suppose the "side" isn't big enough to walk on. If that were the case, then it isn't likely that the force of gravity would be strong enough to hold anything on the "top" of the world either, so the earth would be barren. Keep sending those questions . . . posted
