Dark Energy
From Slackerpedia Galactica
"...the expansion of the universe is accelerating under the influence of a gravitationally repulsive form of energy that makes up two-thirds of the cosmos."
Dark Energy is energy that has been corrupted by the forces of evil. It is used quite often in dark magic and as energy sources for beings of pure darkness or evil.
Dark energy is also believed to be a mysterious force that is behind the expansion of the universe and acts against gravity. Dark energy is believed to currently make up about 70% of the universe. As if that's not bad enough, some physicists (those astronomer-hating heretics) are claiming that black holes do not exist, and are in fact, dark energy stars! As Albert Einstein probably said once, "Screw this, I'm going back to bed."
Dark energy is what keeps cosmologists up at night. They can't figure anything out about it - other than it is there.
