Upsides To Making A Portal To Heaven  
    To   Build   The  Factory  There    
  
                                          
 First Of  All, Real Estate:  The  Highly 
 Fractalized  Geometry  (Not  Proven  But 
 Likely  To  Be The Case) Implies  Almost 
 Unlimited Room; Even  If The Portal Tech 
 Would  Be  Stolen,  Chances  Of  Running 
 Into  A  Competitor Is  Close  To  None, 
                                          
 Secondly,  The  Resources:  Heavens  Own 
 Alchemical  Properties   (Proof  Exist!) 
 Makes  Most  Base Materials  Easily  And 
 Readily Available.  Once  The  Molecular 
 Movement Patterns  Are  Mapped  Out, Any 
 Compound   Can  Be   Created   Virtually 
 Without                            Cost. 
                                          
                                          
  
   Downsides  To Making  A  Portal  To  
   Heaven To  Build The Factory  There  
  
                                          
 Current  Portal  Tech Takes  Some Energy 
 To Hold  Open, Which Isn'T  A Problem In 
 Itself.  Test  Results However Has Shown 
 That Without An  Active Tether, Heaven'S 
 Time Flow Breaks  Down Completely.  Even 
 A  Momentary Fluctuation  Of  The Portal 
 Would    Render    All   Remote   Assets 
 Practically  Lost.  Much  Care  Must  Be 
 Taken  To  Maintain   Portal  Stability.
