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)
