Hi everybody. As I'm sure everybody has been aware, recently Krishna (Spelling?) Prophet has been making some rather in depth posts about why the Earth must be flat. Among Prophet's claims was the idea of the Universal Accelerator, a counterproposal to gravity that conveniently explains why the sun and the moon and the second sun and the imaginary "shadow object" don't fall to the Earth. The Universal Accelerator basically claims that the Earth and all its celestial bodies are all moving upwards at the same rate, which explains why things fall. However, this simply can't be true. Gravity, on Earth, makes objects fall at an easily quantifiable rate, 9.8 m/sec/sec. This means that, every second, the object falls 9.8 m/sec faster than the second before. This INHERENTLY disproves the Universal Accelerator (we'll abbreviate it to UA from now on), and here's why. In a flat-Earth world, we would drop two balls off of a very large cliff. One ball, we'd drop 4 seconds after the second ball. Since the Earth is moving upwards while the balls are not, then it would appear that the balls are both falling to the ground. At the same rate. Since all of the Earth is moving upwards at the same rate it is only logical that the two balls would "fall" at the same rate. However, that isn't how it actually happens. Again, given the proper materials, you can go out and observe this yourself. In the real world (where the Earth is round), you go out to a very large cliff, and drop two balls, the second ball falling 4 seconds after the other. 5 seconds after the first ball started falling they will have very different speeds. The fist ball to drop will have been moving at a speed of 39.4 m/sec. The second ball will have been moving at a speed of 9.8 m/sec. This directly proves the UA wrong, because if you're not pushing any of the balls downwards, in the flat-Earth world, they should be falling at the same rate. However, they aren't. They're falling at very different rates, which means that the Universal Accelerator, and by extension the flat-Earth theory, are impossible.
