   Quantum physics I guess is getting closer by defining the things that make

   speculation right now, isn't it?

   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.

   Funny, I would have thought M-Theory to be outdated by now.
