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)
