A “Boltzmann brain” is the name for an intelligence that would randomly generate itself out of nothing. In some cosmological theories, believe it or not, the number of Boltzmann brains are thought to outnumber every human being who has ever lived or will ever live. By a long shot. Please allow me to explain this odd concept I just learned about a few days ago. Boltzmann was an Austrian physicist, best known for the development of statistical mechanics, who proposed that the entire universe could have randomly generated itself out of nothing, even though that would be a highly improbable occurrence (to say the least). However, if the universe is thought to have existed forever, sooner or later it would have happened, was his reasoning--because even if the odds against something happening are one in one trillion or lower, given infinite time, even something unbelievably unlikely will eventually happen.
