    Dark energy is a hypothetical form of energy that permeates all of space, and increases the rate of expansion in the universe.  Dark energy is used to explain recent observations that the universe is expanding at a very fast rate.  Dark energy accounts for 74% of the total energy in the universe, according to the “standard model of cosmology”.
