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)
