Out of the darkness
Article Abstract:
Earlier studies showed that cosmic acceleration was caused by dark energy. However a recent approach showed that string theory could be the reason for this acceleration that describes the changes in law of gravity bringing about additional directions in which the particles roam.

The quintessential universe; the universe has recently been commandeered by an invisible energy field, which is causing its expansion to accelerate outward
Article Abstract:
Cosmologists have become convinced of the existence of a 'dark energy' in the universe, with a gravity that repels. In fact, the repulsive aspect of the gravity is winning the battle with ordinary matter and the expansion of the universe is increasing at a faster rate.
