This concept has been more successful than Modified Newtonian [new-TOE-nee-un] dynamics at explaining the galaxy rotation problem.
This concept has been more successful than Modified Newtonian [new-TOE-nee-un] dynamics at explaining the galaxy rotation problem. An equation relating average kinetic energy to potential energy called the virial [VEHR-ee-ul] theorem and observations of the Coma cluster were used by Fritz Zwicky in 1933 to predict the existence of this substance. Accounting for about 27 percent of the mass-energy of the universe, identify this substance that does not absorb or emit light and therefore cannot be seen directly.
