Expert Solution
Introduction
Gravity has an essential role in dark energy and dark matter. Gravity is the force of attraction that we feel when we are near an astronomical object. Dark energy is an unknown source of energy in the universe. It resulted from a long-discarded version of Einstein's theory of gravity, called the "Cosmological Constant." Roughly 70% of the universe is dark energy. Its presence is indicated by the unexplained gravitational effect on stars and galaxies.
