Craig Hogan, a physicist at the University of Chicago and the Fermi National Accelerator Laboratory, is building an experiment to see if spacetime isn’t smooth like everyone thinks, but rather bit-like and chunky on the smallest scales. The experiment is the focus of the cover story "Is Space Digital?" in the February 2012 issue of Scientific American, as well as this short video.
