The numbers I've seen suggest that it's feasible to create an oxygen
atmosphere of reasonable pressure in about a thousand years just
scaling existing technology, and that such an atmosphere probably has
a life of around 100 million years.


The slogan 'run the numbers' has always brought a smile as running numbers was originally a product of the 1920's -

Of course the engineers mean it in a different sense but this simulation business on a planetary scale is for those who have no feel for planetary sciences and are just letting their imagination run wild.


It is time for engineers to run the numbers on timekeeping and come to an understanding about the limitations of modeling motions using a system which is founded on astronomical cycles.
