I just read this article:

http://www.washington.edu/news/2012/12/10/do-we-live-in-a-computer-simulation-uw-researchers-say-idea-can-be-tested/

and it said:

"Currently, supercomputers using a technique called lattice quantum chromodynamics and starting from the fundamental physical laws that govern the universe can simulate only a very small portion of the universe, on the scale of one 100-trillionth of a meter, a little larger than the nucleus of an atom, said Martin Savage, a UW physics professor.

Eventually, more powerful simulations will be able to model on the scale of a molecule, then a cell and even a human being."

It occurs to me, that if this were to become a reality, there is the question, what does the simulated human being know about its world?

Will the simulated measurements of the simulated human being match exactly the data of the underlying model?

The BIG question: is it possible to construct a simulation of reality that isn't identical to or consistent with quantum chromodynamics, yet the simulated measurements of the simulated human being are in perfect agreement with quantum chromodynamics?

In other words, in a simulated universe, if we were to perform the double slit experiment, how would the data of the simulation compare to the information contained in the simulated brain of a simulated observer?

How does our "God's Eye" view of the simulation compare to the view of the simulation's internal observer?
Any predictions?

It occurs to me this is the proper interpretation of quantum mechanics. That you didn't have to put quantum mechanics into the model. You're supposed to get it out of the model, through the measurements of an internal observer.
