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.
