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.
