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)
