An article inked from the linked article quotes another article as saying,
"the problem with all simulations is that the laws of physics, which appear continuous, have to be superimposed onto a discrete three dimensional lattice which advances in steps of time"
This is false. It may be the assumption of this approach, but it's not so. I've worked with non-time-stepped simulations and adaptively-time-stepped simulations. I've also worked with non-lattice, non-3D simulations.
Of course the original article comes out and says it, but it bugs me that this explicit assumption ended up cast as a conclusion.
Surely one can simply manipulate the four-(or eleven)-dimensional equations directly, rather than trying to make a measurement of a continuous object with a tool that only measures discrete states?
If it is... I hope they do not crash the system with the test.

Be sure to check out the actual reseach papers linked in the article! I would have linked to them directly, but the article is full of follow-on links of considerable interest.
