The Matter of Everything (in TlhIngan Hol: HapHoch) was an organization of civilian scientists from the Federation, Klingon Empire, Cardassian Union, and other worlds, dedicated to creating a unified theory of the nature of the universe. In the 2370s, the Klingon High Council condemned the work of the MOE. Similar work had been at the Klingon Science Institute by a Klingon scientist named B'Ekara, but she was fired for integrating into her work the theories of Kleissu, a Mizarian scientist. Both joined the MOE shortly thereafter.
