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.
