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.
Michael Moyer is the editor in charge of physics and space coverage at Scientific American. Previously he spent eight years at Popular Science magazine, where he was the articles editor. He was awarded the 2005 American Institute of Physics Science Writing Award for his article "Journey to the 10th Dimension," and has appeared on CBS, ABC, CNN, Fox and the Discovery Channel. He studied physics at the University of California at Berkeley and at Columbia University.
