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)
