In a recent Scientific American piece Is Space Digital ? Michael Moyer profiles an experiment getting started outside of Chicago which will attempt to measure the intimate connections among information, matter and spacetime. Lead by Craig Hogan a physicist at the University of Chicago and director of the Fermilab Particle Astrophysics Center near Batavia, Ill., the experiment will grapple with concepts such as the Planck scale and the holographic principle.

Mr. Moyer explains: 

Physicists have, over the past couple of decades, uncovered profound insights into how the universe stores information—even going so far as to suggest that information, not matter and energy, constitutes the most basic unit of existence. Information rides on tiny bits; from these bits comes the cosmos. If we take this line of thinking seriously, Hogan says, we should be able to measure the digital noise of space. Thus, he has devised an experiment to explore the buzzing at the universe’s most fundamental scales. He will be the first to tell you that it might not work—that he may see nothing at all. His effort is an experiment in the truest sense—a trial, a probe into the unknown. “You cannot take the well-tested physics of spacetime and the well-tested physics of quantum mechanics and calculate what we’ll see,” Hogan says. “But to me, that’s the reason to do the experiment—to go in and see.”
And if he does see this jitter?
