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)
