Dark Matter

Matter that produces no detectable energy, but that reveals its presence through its gravitational pull on the visible matter around it. Dark matter makes up more than 90 percent of all the matter in the universe. There are many possible forms for dark matter, but most current theories suggest a subatomic particle created in the Big Bang.
