I mean we can observe finite mapping of the mathematical
  world onto physical universe. Which in itself is a wonder,
  because it exists. I find no reason for it to be so, 
  otherwise that it is related through common substance. 
  
  Even Reals are not real.
  
  Math is mental. Math objects are infinitely larger
  than physical world.
  
  Material universe is a special case of mathematical world.
  because you can construct infinite physical worlds if you 
  choose different relations from the infinite.  
  
  You can observe infinite worlds through consciousness. 
  Only one of them is physical. 
  
  If there is a hypothetical one to one mapping of 
  physical world onto a set of models then consciousness 
  is larger than the physical universe. 
  
  The question is whether that is true. 
  How much of the physical universe is 
  unknowable in principle.
  
  If the material world > consciousness, then there 
  exist things that are possible to observe, but 
  impossible to know. 
  
  And the converse, if consciousness > material world
  then there exist things that are impossible to observe, 
  but possible to imagine.
  
  I mean there is physical brain, neurons, observations 
  and other stuff which is strongly relating self body 
  and consciousness. But maybe it is so by design? 
  
  The question is what is the difference 
  between me being a brain and me imagining 
  being a brain.   
  
  That is my take into it as I am approaching 30. We will
  see my opinion later in life.
