In a nutshell, somebody calculated that if space is really granular at 1e-35 meters, that should actually affect the propagation of polarized gamma rays from a GRB 300 million light years distant, in a measurable way. Measurement found no such effect, apparently showing that the universe calculates space down to at least 1e-48 meters.

Uh huh. Or maybe space is granular at the 1-cm scale - and there's a large state-space per cell.

Or maybe it's being run on a one-dimensional cellular automaton or a Turing machine etc. What of it? Regardless, the system in question is simulating space with, apparently, a granularity of at least 1e-48 meters, and there remains the question of whether it is using finite or infinite computing power.
