We used a rotating torsion pendulum containing ≈1023 polarized electrons placed in an orientable quadrupole source to constrain Bonder and Sudarsky's quantum-gravity effect based on a Lorentz-invariant spacetime granularity model proposed by Corichi and Sudarsky. Our null results constrain the model's free parameters 13 orders of magnitude more tightly than those Bonder and Sudarsky obtained by reinterpreting the data from a previous polarized neutron experiment that was designed to test Lorentz invariance.
