> However, Savage said, there are signatures of resource constraints in present-day simulations that are likely to exist as well in simulations in the distant future, including the imprint of an underlying lattice if one is used to model the space-time continuum.

They did their experiment and did not find anything that would indicate an underlying lattice, but I can't find the paper right now.
