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)
