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)
