Dark energy is an unknown form of energy that radiates from deep space. It behaves in the opposite manner from gravity. Rather than pulling galaxies together it pushes them apart. Dark energy makes up the bulk of the universe's mass/energy budget. If dark energy is stable the universe will continue expanding and accelerating forever. If dark energy is unstable the universe could ultimately come unglued to the point where stars, planets and even atoms come apart, a doomsday scenario called the "big rip." Dark energy might also flip such that is becomes an attractive force and causes the universe to implode in a "big crunch."
