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)
