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)
