Our current description of the basic interactions in nature, based on the standard model of particle physics and general relativity, is in spectacular agreement with all known experiments. However, it is almost certainly fundamentally incomplete. In addition to difficulties associated with strong quantum gravitational effects at the Planck length the extreme weakness of gravity relative to the other forces, and the huge size and flatness of our observable universe, suggest that we are missing a big part of the picture. Nima Arkani-Hamed's research in theoretical physics is driven by attempting to address these mysteries.
In 2008 Arkani-Hamed won the Raymond and Beverly Sackler Prize given at Tel Aviv University to young scientists who have made outstanding and fundamental contributions in Physical Science. In July 2012, he was an inaugural awardee of the Fundamental Physics Prize, the creation of physicist and internet entrepreneur, Yuri Milner.
