(urth) spatial temporal rules of astral travel

[António Pedro Marques]

I like parts of your exposition, Marc. It only seems to me that after a 
number of insights and interesting deductions, some of your conclusions 
(Urth = Green (or Blue, even, if it were), the time lapses) are not up to 
the same standard. You've built quite an interesting building, but I don't 
think the roof matches the awesomeness of the rest.
