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)
