Rubin found anomalous rotation curves in spiral galaxies that implied the existence of this that caused velocity to stay constant with radius. The WMAP experiment excluded the warm type of this, and Zwicky postulated the existence of halos of this material. Baryonic forms were not found in enough abundance in astronomical surveys, leading WIMPs to be considered the main component of this, and the existence of its cold type is part of the ΛCDM  model. This substance makes up 24% of the mass-energy of the universe. For 10 points, name this substance detected through its gravitational effects because it neither emits nor scatters electromagnetic radiation.
