Flat Earth General / Final nail in the FE theory

« on: November 20, 2011, 12:32:51 PM »

I know FEers dispute Space Flight images as part of the conspiracy, but here's something anyone can do with a bit of money: . The video clearly displays an Earth quite different from the FE model (yes, I know the lense is curved), and, at 90,000 ft, I see no spotlight Sun. Anyone can repeat this experiment for more conclusive results. I dare a FEer to get a picture of the edge of the Earth, or of the spotlight Sun.

Flat Earth Debate / Equitorial problems

« on: November 20, 2011, 09:31:12 AM »

At the Round Earth's magnetic equator, to travel east or west, one can simply move in one straight direction, without having to make slight curves or anything that you would on another part of the globe. However, on the Flat Earth, to travel around the equator one would have to constantly move in a curve. Thus, we can pretty accurately test the Flat Earth Theory by sailing or flying part way around the equator.

In addition, the geographic equator, according to the Flat Earth model, would be 31,473 km. However, its measured length is much larger, at 40,030 km.

Finally, the Sun, according to the FE model, travels in a circular motion around the equator. What force provides the centripetal acceleration? Especially considering the center of the circle that it makes would be some 300 miles above the North Pole, which is empty space.

Flat Earth Debate / Scientific observations of the Flat Earth

« on: November 19, 2011, 04:49:13 PM »

Hello, I am Mr. Anon, and I'm kind of new here. I am familiar with many experienced physicist, and as a result here are some scientific observations I have made about the Flat Earth notion.

Gravity

First off, this is the biggest thorn in the FET in existance. Gravity has been proven; I have seen experiments that display very small forces between two masses. This poses a significant problem for the Flat Earth. Even a very thin disc the size of the Earth would have a mass large enough to fold itself into a sphere. The Flat Earth version of gravity, the proposed Universal Accelerator, simply does not work. Even at the creationist view that many Flat Earthers embody, where the Earth is only 6000 years old, the disc, accelerating constantly at 9.8m/s/s, would have long ago exceeded the speed of light. While this can be explained to an extent with relativistic effects, the result is that the rest of the universe would rapidly age compared to us, and as we approach the speed of light, the acceleration we feel would decrease. In addition, the energy required to maintain such an accelerator would be tremendous (I don't even want to calculate it, though I could, as I'd have to add the masses of the Earth, planets, and the Sun and Moons). In addition, the UA does not account for the observed slight decreases in acceleration that have occurred at higher altitudes.

Ice Wall/Antarctica

The Ice Wall also poses some challenges for the FET. There have been recorded journeys that have been made across the Antarctic continent, as well as some plane travels. In addition, the inside circumferance of such an Ice Wall would be far greater than the measured circumferance of Antartica, and also would contradict nautical journeys, where (going clockwise according to the North Pole) sailoirs would end up constantly turning West instead of East. I am aware of a second FET map, where Antarctica is still and island-continent, but this map severely distorts the Pacific Ocean, and also does not create any means of keeping water from spilling over the edge of the Earth.
