Dark matter. Written By: Dark matter, a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 26.5 percent of the matter-energy composition of the universe; the rest is dark energy (73 percent) and âordinaryâ visible matter (0.5 percent).
Dark matter, if it exists, is matter that does not interact via the electromagnetic force (of which the force carrier particles are photons, hence it can not be seen) and it does not interact via weak or strong force either. Dark matter interacts gravitationally - this is how we suspect that it might exist.
