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.
