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)
