CNN: Geniuses who will change your life
#7. Nima Arkani-Hamed, particle physicist and applied string theorist Nima Arkani-Hamed thinks big. He has a theory that our universe is one of an infinite number of universes -- meaning the largest thing we can wrap our minds around is actually pretty tiny. He didn't pull the "multiverse" out of thin air, though. After becoming a Harvard professor at age 30, Arkani-Hamed first made a name for himself by suggesting that our universe is five-dimensional. Then he moved on to the multiverse, theorizing that our own universe has a hidden feature called "split supersymmetry," which means that half of all particles have partner particles. The theory will be tested soon in Switzerland's brand-new Large Hadron Collider (LHC), and if the LHC finds Arkani-Hamed's partner particles, it could prove that the multiverse is real -- and that our place in it is that much smaller >>> Also see Pardis Sabeti
