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)
