Dark matter is not the same as dark energy.

  Dark matter did include dark energy for a while, according to the article... > starting from the 1980s, the new cosmological dogma was that dark matter constituted a staggering 95 percent of all matter in the universe. That lasted, well, right until the bomb hit us in 1998. It turned out that the expansion of the universe is accelerating, not decelerating like all of us originally thought. Any form of genuine matter, dark or not, should have slowed down acceleration. And so a whole new type of entity was invented: Dark energy. Now the accepted cosmology is that the universe is made up of 70 percent dark energy, 25 percent dark matter, and 5 percent regular matter. But dark energy is just a quick fix, the same as dark matter is. That makes it sound like dark energy is an offshoot of dark matter, a different type of dark matter that explains an accelerating expansion instead of the extra gravitational effects.
