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.
