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)
