Carl Friedrich Gauss's Theorema Egregium proved that a sphere cannot be represented on a plane without distortion. Since any method of representing a sphere's surface on a plane is a map projection, all map projections distort. Every distinct map projection distorts in a distinct way. The study of map projections is the characterization of these distortions.http://en.wikipedia.org/wiki/Map_projection
That being said, the FET has to make different predictions. Can't any of you guys who do believe the theory go around measuring the world? It would be absolutely awesome to find out that the FET theory is indeed correct.
Also, the distance problem seems to be a bit more noticeble when it comes to daylight time. The FET, from what I've read, makes very different predictions for the day time for southern countries. For example, argentina, during a equinox, would NOT be receinving 12h of daylight. As a matter of fact, I challenge anyone here to give any reasonable explanation on how could EVERY country in the world get EXACLY 12h of daylight as it happens twice a year.
Not only that, but you must also remember that there are regular aircraft lines on the south hemisphere, say, from australia to argentina, or from brazil to south africa. Now, the important thing to remember is that most airplanes cannot travel above the sound speed and they usually travel quite close to it. Therefore, if the distances are indeed inacurate, the airplanes would have to break the sound barrier which is IMPOSSIBLE. Even on short flights on the south, say regional flights in argentina, australia or new zeland, the airplanes would have to break the sound barrier. Conspiracy is simply not an option here because it would involve millions of people (myself included).
