   Quantum physics I guess is getting closer by defining the things that make   
   quarks as "bends" in the fabric of spacetime, but it's still basically   
   speculation right now, isn't it?   
      
   Currently physicists are trying to join their two most fundamental theories -   
   quantum mechanics and general relativity - into a consistent single theory   
   ("quantum gravity"). The leading candidate for this single theory is M-theory   
   (unification of    
   different versions of string theory), where elementary particles are   
   two-dimensional strings or higher-dimensional objects whose mode of vibration   
   in spacetime determines their physical properties. And as a bonus, space must   
   have 10 dimensions, not just    
   3. Who knows when we will be able to test this theory empirically.   
      
   Anyway, in my metaphysics reality consists of things or stuffs (elements of   
   reality) and mathematical/logical relations between them. These relations are   
   ultimately reducible to three fundamental, logically necessary, relations:   
   similarity, composition    
   and instantiation. So spacetime, like anything else in reality, is things with   
   relations among them.
