   That's funny, even vacuum is not vacuum, even there you need to worry about   
   resistance of dust, ISM, solar wind etc.   
   I wonder if there is a way to calculate strenght of this bump, and behavior of   
   whole shockwave, and how big is it.   
   Turning on the "bubble shield" only in turnaround is nice idea, offers both   
   protection and initial braking.    
      
   "Oh. We've been assuming the ship fires main engines while still in the origin   
   system, haven't we? There's gonna be another couple of "exciting" moments when   
   the ship crosses out of their origin star's heliopause, and when it crosses   
   into the target    
   system's star's heliopause."   
      
   What kind of "exciting moments" Are on your mind? Some space auroras, exhaust   
   deflections, plasma flares?   
      
   "When flying frontward, yes, but flying backward the spray is being sprayed   
   where the ship was, not where it's going to be. It has no way to catch up"   
      
   Hey, but wouldn't this mean, that when I throw a ball in our rocket while   
   braking it won't fall (Assuming vacuum in a room)?    
   Uhh, the heat, worst enemy of High Powered Rockets. Does it make sense to have   
   backup radiators, nanotube array or something like this, for emergency   
   situations when ship manevuers so the spray will fly all over the space? Could   
   it handle the heat for    
   short amount of time?    
   As to the end of your post - when I found this group, I have read many   
   threads, but to be honest I don't remember a lot from them.    
   That's all for now, maybe I will post some notes to rest of your text, but it   
   seems legit to me :p
