It sounds like an Onion headline, but it’s the strange truth: A handful of government physicists believe that we may be existing in a two-dimensional hologram. Yesterday Fermilab, a U.S. Department of Energy Office of Science laboratory, unveiled a set of groundbreaking experiments that will uncover whether or not we live and breathe in a holographic reality. Like characters in a TV show, who don’t know that their 3-D-esque world only exists on a 2-D screen, it’s possible that our perception of three-dimensional space and the universe is merely an illusion, scientists say.
