         Cheers,

           1. What do we mean by saying 'empty space at given time'? 
         When we say "nothing is there [pointing] now," the now is
         unable to refer to any time reference except where we are,
         but where-when we are pointing.

           2. Can time truly be the transportation of energy?  A point
         object with zero energy "movement" still exists.  Time
         continues.  Unless I am greatly misunderstanding the 'time as
         energy vehicle' approach, it doesn't make sense in this
         respect.

           3. What do we mean by space-time?  We say it means every
         object at every moment is given four unique coordinates. 
         This vector has x, y, z for physical position and t for
         temporal position.  Let us examine (x',y',z',t') and let us say
         there is not an object or energy "there."  Meaning, E=mc^2=0
         for said point/perspective.  The sentence "The point
         (x',y',z',t') exists." has no meaning.  There is no
         perspective of the rest of the universe--no photons are
         relaying information or connecting that point to the universe
         by light cones.  There is apparently no way to get to that
         place-time or to leave that place-time.

           4. A PARADOX!!  It would seem that #3 leads us to believe
         that empty space cannot exist.  Return of the ether theory? 
         (Oh no!)

           5. It would seem that the space-time theory limits all
         knowledge to the here-and-now.  I can't even figure out what
         my friends are saying to me because they are over THERE.  I
         cannot remember what I was just doing because that isn't NOW.


           Someone asked for general ideas about time and I think,
         generally.  Take my ponderings for what they are worth, but
         not arguments toward anything.  Does this paradox seem
         similar to Zeno's?
