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)
