The definition of dark energy in the field of physics is a hypothetical form of energy that is believed to permeate all of space and possesses negative pressure. It is called "dark" because it does not interact with electromagnetic radiation, making it invisible and difficult to detect directly. Dark energy is thought to be responsible for the observed accelerated expansion of the universe. Its exact nature and origin, however, remain unknown.
