Deletion of Colonization of Trans-Neptunian Objects

Comment: This is not a matter of . The article deals with the ongoing theoretical discussion of what such colonization will entail. It contains information from what some leading theoreticians have proposed. It is of scientific, educational, and encyclopedic interest. It is not random cruft. This sort of discussion has taken place for all the Colonization articles.  It is as notable a subject as the other, more firmly established, survived AfD articles about Space Colonization. If Sagan and Dyson aren't notable enough as authorities, than who is? As has been said in other AfD's, deletion is not a cure for bad writing. The cure for that is clean-up, expansion and editing
