=== Overview === '''Dark Energy''' is a mysterious and pervasive form of energy that constitutes approximately 68% of the total energy density of the universe. It is hypothesized to be the driving force behind the accelerated expansion of the universe, a phenomenon that has been observed through astronomical measurements such as the redshift of distant galaxies. Unlike ordinary matter and dark matter, which exert gravitational attraction, dark energy has a repulsive effect, causing space itself to stretch and expand at an increasing rate.
