   When they talk about warping in this context, they are talking   
   about curving space.  For example, if you lay out a series of   
   grid lines in space, those line will tend to curve towards objects   
   with high gravity.  It has nothing to do with a space ship going   
   faster than the speed of light.

   But in no case can you go faster than C, the absolute speed of   
   light.  In the case of Cherenkov Radiation, they are talking about   
   going faster than the speed of light in a given medium where that   
   speed of light is less than C.  When the speed of light in a   
   given medium is the same as C, the effect evaporates.  So, for   
   example, one can go faster than the speed of light in water since   
   the speed of light in water is less than the absolute speed of   
   light.  That doesn't help us in space travel since outer space   
   is essentially a vacuum.

   I don't mind people calling in and giving their personal stories,   
   other than the ghost stories.  I get kind of tired of that quickly.   
   If that many people are having these unusual experiences, then I   
   don't object to research into those areas.  What I do object to,   
   however, are people making up all these foo-foo theories and   
   representing them as science or the truth.
