What did the Fermilab Holometer actually find?

Two 39-meter interferometers. Five years of data.

One null result.

Hogan's model, what it tested, and what it couldn't.

REAL SCIENCE: Fermilab is building a holometer to prove that the third dimention is real, and not just an illusion: http://www.popsci.com/science/article/2010-10/fermilab-building-holometer-determine-if-universe-just-hologram
Fermilab is Building a 'Holometer' to Determine Once and For All Whether Reality Is Just an Illusion
Researchers at Fermilab are building a "holometer" so they can disprove everything you thought you knew about the universe. More specifically, they are trying to either prove or disprove the somewhat mind-bending notion that the third dimension doesn't exist at all, and that the 3-D universe we think we live in is nothing more than a hologram. To do so, they are building the most precise clock ever created.

NASA Astronomy Hourly Picture - 2014-09-02: Holometer: A Microscope into Space and Time
#Astronomy #NASA #Space
How different are space and time at very small scales? To explore the unfamiliar domain of the miniscule Planck scale -- where normally unnoticeable quantum effects might become dominant -- a newly developed instrument called the Fermilab Holometer has begun operating at the Fermi National Accelerator Laboratory (Fermilab) near Chicago, Illinois, USA. The instrument seeks to determine if slight but simultaneous jiggles of a mirror in two directions expose a fundamental type of holographic noise that always exceeds a minimum amount. Pictured above is one of the end mirrors of a Holometer prototype. Although the discovery of holographic noise would surely be groundbreaking, the dependence of such noise on a specific laboratory length scale would surprise some spacetime enthusiasts. One reason for this is the Lorentz Invariance postulate of Einstein's special relativity, which states that all length scales should appear contracted to a relatively moving observer -- even the diminutive Planck length. Still, the experiment is unique and many are curious what the results will show. Astrophysicists: Browse 900+ codes in the Astrophysics Source Code Library

So after looking at that, and at even more other sources, there's still no evidence that the planck size is related to space-time grain size, and there seems to be multiple physically real effects with smaller sizes.
