Super-Continent Missconception
 Current continental drift theory which suggest a super continent exist on one side of the planet defies the laws of physics. The material that makes up rock is much denser than water. When you examine the current distribution of mass on the planet, and keep in mind the laws of gravity, the bulk of the mass exist in quasi pyramid structure which is a result of the global equalization of these laws. The only way a mass continent would be formed would be if the earths crusts was too thick for the continental drift to even work(mass of the super continent is insignificant in comparison to the relative mass of each existing crust-really thick) . Redistribution of the oceans is a constant that happens and should be calculated into any and all standing theroms.
