Flat earthers are saying that we don't live on a sphere because a sphere spinning at 1000 miles per hour would fling everything off of it lickity split. I beg to differ because our mysterious friend "perspective" comes to play again and can prove that their reasoning is flawed. I propose that they are misunderstanding the concept of perspective speed, they forget that speed is relative to the perspective of the viewer, they are not factoring in the fact that the further something is away from you, the slower it appears. If I have an airplane whizzing past me at 200 mph and it's only 100 feet away from me, its probably going too fast for me to even recognize what it was. But, if that same plane going 200 mph were 400 miles away from me it would appear to be moving quite slow and I would have enough time to take in every detail i could make out and even time enough to ponder it for a while before it left my sight. I use this example to introduce the reason why the world spinning at 1000 miles per hour isn't really that fast after all. Let's use a gear for instance, a gear that is 1000 miles in circumference, we will call it gear A and let's imagine that it is set in motion and spinning 1000 miles per hour, or one revolution per hour, now let's imagine a gear that is only 1 mile in circumference, we shall call it gear B, spinning at that same 1000 miles per hour, or 1000 revolutions per gear A's one revolution. It doesn't take much to imagine that gear B is spinning a phenomenal amount faster than Gear A is, but they are both going the same speed. What I am proposing is that due to perspective, the earth which is supposed to be 25,000 miles in circumference is only spinning at 1000 mph, that it is actually spinning quite slowly because it is taking 25 hours for it to reach one revolution. The same forces that are in effect that causes a road to appear narrower with distance applies equally to the slower speed of an object the further away it gets. Also, with the idea of leverage when lifting with a fulcrum and lever, the further away you are from the object the lighter it appears. The rule of thumb appears to be the further away things are, the more decreases are experienced, including time and distance. The most amazing thing about it, is that thanks to perspective, the plane that was mentioned earlier is moving breathtakingly fast and painstakingly slow at exactly the same time. You will hear flat earthers mention that the speed is too fast for things and should cause all sorts of disruptions, but I stand firm that their theories are for lack of perspective and relativity.
