2007 Gruber Cosmology Prize Saul Perlmutter and Brian Schmidt and their teams: the Supernova Cosmology Project and the High-z Supernova Search Team, independently discovered that the expansion of the Universe is accelerating. Their discovery led to the idea of an expansion force, dubbed dark energy. And it suggested that the fate of the universe is to just keep expanding, faster and faster.       Saul Perlmutter & the Supernova Cosmology Project                   Brian Schmidt & the High-z Supernova Search Team
