Experiment probes nature of space and time Scientists listen for 'holographic noise' at the universe's smallest scale By Carla Reiter Photo by Reidar Hahn/Fermi National Laboratory “ In a way, for me, this thing has already succeeded exactly as we hoped, because it’s guiding theory.” —Prof. Craig Hogan Head of Fermilab’s Center for Particle Astrophysics For the past year at , an instrument called has been probing the fundamental nature of space. The experiment uses an array of lasers and mirrors to try and answer the question, “If you look at the infinitesimally small scale, is space smooth and unbroken—the way we experience it in everyday life—or is it pixelated like the image on a TV screen?” Recent initial results are homing in on an answer. Either way, the outcome will have important c
