   Now one thing that always fascinated me about this Roche limit is the   
   question   
   of what would happen if two bodies of exactly equal mass would cross each   
   other's   
   "Roche limit". I mean is the Roche limit different for each pairing or is it   
   a total   
   boundary, similar to the "event horizon" of a black hole?   
      
   But the bottom line of my questions was actually on wether such a   
   gravitational   
   map as that one produced by Grace would even make sense, given that all   
   these factors constantly change the earth's grav appearance.   
   Wouldn't they have to keep updating that mapp all the time?

   Well I read of hot gas erruptions and even moon quaked having been measured   
   w/o any meteorite impacts. An they said these where caused by grav tides   
   from the earth' influence on the moon.   
      
      
   >The tidal deformation of the body of the Earth is called an "earth tide,"   
   >just as the tidal deformation of the ocean is called an "ocean tide."   
      
   Now wouldn't all these grav tides suffice to destract the streams of matter   
   flowing inside the body liquid of the inner earth?
