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)
