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)
