Consider a section of space-time which contains a perfect vacuum.  What
is the space-time?  Does it have temperature (3 degrees K)?  How does
it exist?  It must be curved (in a relatavistic universe) so there must 
be something to be curved.  But if there is something, it must be 
constructed of particles, so it can't be a vacuum.  Or is space-time
not constructed of particles?  If not, what can it be constructed of?  Will
space-time and matter be unified one day?  (No, I don't expect a definitive
yes.  Maybe a definitive no though).
