The Bethe/Brown kaonic state is only stable for a few seconds, just long
enough to explain the delay in neutrino emmision (from supernova
1987A). It is postulated to be a gigantic, star-wide Bose-Einstein
condensate. Such a state cannot support much diversity, as all the
particles are in the same (for certain parameters) quantum state.
