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.
