**Flat Earth Debate / Re: A plea for rational argument on the boards!**

I do not have any "job" here. This is a FLAT EARTH board. YOUR job is to convince us that you're not all raving lunatics.

Fine... you want proof that the Earth is round... here it is: Gravity pulls with equal strength in all directions; therefore any variations from a spherical shape will lead to gravitational forces that bring the shape back into that of a sphere.

I knew you had no evidence.

In case you're too stupid to understand why you're wrong: Any single point on the Earth has equal gravitational pressure from both sides. Infinity divided by 2 equals infinity. Therefore the Earth CANNOT collapse.

Collapse? I said nothing about the earth collapsing, in fact if the Earth were not round, whole hemispheres would have different atmospheric pressure and significantly different sea levels. Now for more proof for you to choke on: You can launch a rocket to a high altitude and take pictures of the earth (which various government agencies and private groups have already done thousands of times in the past), but that isn't the most practical way. Pictures and videos taken by orbiting satellites and space stations are certainly the most definitive proof that the earth is a sphere.

But if you're not convinced, read on...

You can also observe, with binoculars, ships slowly 'sinking' below the horizon as it sails farther and farther out to the ocean, then watch them come back. They certainly didn't fall off the edge of the earth! You can also sail or fly around the world.

The Greeks discovered that the earth is round by observing lunar eclipses (i.e. when the earth blocks the sun from the moon, casting its round shadow on the moon's surface).

Another method is simultaneously measuring the length of the shadows cast by identical poles perpendicular to a flat surface that is tangential to the earth's radius at various, distant locations. If indeed the earth is round, then the shadows should all vary in length from one distant location to another, which means that the angle at which the parallel rays of sunlight struck each pole varied from one location to another. (recall the alternate-angles theorem from Geometry class) If the earth is flat, then the lengths of all the shadows should be identical when measured simultaneously, since all rays of sunlight that strike the earth are parallel. However, they are not identical, but in fact, varies in such a way that the angles indicate a spherical surface. (This was one of the earliest methods to determine the radius of the earth)

Also, keep in mind the 24 hour time zones. When it is noon in Hawaii, it is approximately midnight in the Middle East and vice versa. How can it be noon and midnight simultaneously? It is certainly impossible with a flat earth and a sun millions of times more massive.

Now, I will take your proof... or as the rest of us call them; Insults.

believe me they have answers for all that crap... its nonsense yes. but they have answers
