Craig Hogan has worked in many areas of cosmology, encompassing the origins of the elements, cosmic structure and dark matter, magnetic fields and gravitational waves. He was part of the High-Z Supernova Search Team, which discovered “dark energy,” the force behind the acceleration of the universe. Two members of this team were awarded the 2011 Nobel Prize in physics for the breakthrough.
He recently began an experiment that could address one of the most nagging problems in physics: how to reconcile Einstein’s General Theory of Relativity with quantum mechanics. He uses the world’s most sensitive laser interferometer, the Holometer at Fermi National Accelerator Laboratory, to explore the fundamental nature of space. This experiment should help us understand whether space is smooth and unbroken or pixelated like the images on a TV screen.
A fellow of the American Academy of Arts and Sciences and the American Physical Society, Hogan has chaired and been a member of NASA’s Astrophysics Subcommittee. His many honors include the 2015 Breakthrough Prize in Fundamental Physics, the Gruber Cosmology Prize, and the Alexander von Humboldt Research Award. Hogan wrote The Little Book of the Big Bang, which has been translated into six languages.
