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)
