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)
