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)
