Article The Model

This article is intended to formally demonstrate that, in the universally accepted model of the Moon, the mathematical disk representing it does not spin. Any debate on the Moon itself will remain futile and even pernicious as long as one is convinced that the disk spins. This is why the other pages of the site are protected by a password which you can obtain on request from the article “The Model”.
