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)
