Edge of the Earth

I was showing how a finite earth could work without the atmosphere leaking away.

The air would be lost from what I can tell. In the same way if you make a tower of water and let it go, the water will spread apart, and if the outsides were so cold that they were to make the water frozen, the warmer water in the centre will still have some force to it and push the frozen water out further.

@New Earth, stick around till after December '12 so I can rub it in, please

And everyone, I have a noob question about the edge of the earth.
what keeps the air from falling off?

See the Atmolayer Lip Hypothesis:

Atmolayer Lip Hypothesis

The Flat Earth does not necessarily need to be physically infinite in order to contain the atmosphere. Just very big. Often we might hear "infinite earth" from Flat Earth proponents as an analogy for what exists beyond the 150 foot wall of ice at the Antarctic coast; a stretch of land incomprehensible by human standards.

In order for barometric pressure to rise and fall, an element of heat must be present. Heat creates pressure. A lack of heat results in a drop in pressure. These two elements are tightly correlated in modern physics.

In our local area the heat of the day comes from the sun, moving and swashing around wind currents from areas of low pressures to areas of high pressures with its heat. The coldness of the Antarctic tundra keeps the pressure low. Beyond the known world, where the rays of the sun do not reach, the tundra of ice and snow lays in perpetual darkness. If one could move away from the Antarctic rim into the uncharted tundra the surrounding temperatures would drop lower and lower until it nears absolute zero. Defining the exact length of the gradient would take some looking into, but at a significant distance past the edge of the Ice Wall temperatures will drop to a point where barometric pressure nears the zero mark. At this point, whether it be thousands or millions of miles beyond the Antarctic rim, the environment will gradually match that of background space, and the world can physically end without the atmosphere leaking out of it.

The atmosphere may very well exist as a lip upon the surface of the earth, held in by vast gradients of declining pressure.

Tom, I'm glad you consider the Ideal Gas Laws to be the absolute truth, and that any considerations about molecular energy and momentum are irrelevant.
