Eighty five percent all the gravity in the universe comes from something about which we know nothing. ...Neil deGrasse Tyson
[Add that to dark energy and] it is ninety six percent of the universe. Everything we know and love--electrons, protons, neutrons, light, black holes, planets, stars, everything we know and understand--occupies four percent of the universe. Dark matter and dark energy is everything else.
