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. 
 (One Option Could  Be  Several  Portals)
