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)
