What Fermilab�s Holometer Experiment teaches us about Quantum Gravity.

The Fermilab Holometer searched for
correlations between two interferometers

Tl;dr: Nothing. It teaches us nothing. It just wasted time and money.
The Holometer experiment at Fermilab just published the results of their search for holographic space-time foam. They didn�t find any evidence for noise that could be indicative of quantum gravity.
The idea of the experiment was to find
