Hi Edgar,

  I like Kevin Knuth's theory of emergent space time. It is far more simple 
and does not need to get into quantum aspects other than a basic notion of 
an observer. An observer is a simple entity whose state is changed as the 
result of an observation/interaction: A nice video of one of his talks can 
be found on the Perimeter Institute website.
