   No, there are techniques for cooling antiprotons, which are routinely   
   applied by the accelerator guys to keep the stuff around longer.  Usually   
   they don't cool it all the way down to zero, but there's no fundamental   
   obstacle to doing so.  (Last I heard, the one tricky part was thought to   
   be condensing the antihydrogen to a solid.)
