Hi Peter
very interesting ! More and more simulation / VR stories appearing all the time now
Good find

I have found a similar article from Slashdot: http://phys.org/news/2012-10-real-physi ... ation.html and http://arxiv.org/abs/1210.1847

Here some interesting quotes from the article:
First, some background. 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.
[...]
They say that the lattice spacing imposes a fundamental limit on the energy that particles can have. That's because nothing can exist that is smaller than the lattice itself.

So if our cosmos is merely a simulation, there ought to be a cut off in the spectrum of high energy particles.

It turns out there is exactly this kind of cut off in the energy of cosmic ray particles, a limit known as the Greisen–Zatsepin–Kuzmin or GZK cut off.
The last part of the article explain how they would measure the lattice... they lost me from there. Would need some help understanding correctly this part ;)
