Look, lets say the radius of our inner circle is 3112 miles, mkay? So what's its circumference? 6114pi, right? Now, the second circle, the other tropic, is around 9336 miles, so its now 18672pi or something, right? Now, divide, and you get 4x just at the tropics. Now lets say we go to our little thing over at very close to the North Pole, and all the way to the South of the Earth. It's going to get bad, isn't it? And yet, in RE, the two are equal. So, if a ship down all the way near Antarctica is going in RE speed of about 20-30 knots, in FE, it must be going at 80-120 knots, at the very least, yes? Probably far more. And Char70ger is right about what I mean.
