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).
By Andrew Zimmerman Jones. Definition: Dark energy is a hypothetical form of energy that permeates space and exerts a negative pressure, which would have gravitational effects to account for the differences between the theoretical and observational results of gravitational effects on visible matter.nstead of a steady expansion, or a slowing expansion, the expansion rate is getting faster, which means that Einstein's original cosmological constant prediction manifests in today's theories in the form of dark energy. The latest findings indicate that over 70% of the universe is composed of dark energy.
