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)
