Dark Energy is the enigmatic cause of the acceleration of the cosmic expansion. Since the discovery of acceleration in 1998, scientists are trying to understand the nature of the substance that drives the cosmic kinematics. The cosmological constant introduced by Einstein in 1917 is a possible explanation, | Dark Energy is the enigmatic cause of the acceleration of the cosmic expansion.
