Abstract
The author will show that the acceleration of the Universe expansion can be explained by coordinate transformation from the author's physical metric to FRW (Friedmann Robertson Walker) metric. The physical metric introduced by the author fits the experimental data, in particular that of time delay experiment of Shapiro et al. The author will present a new way of understanding the nature of gravity. It has a nature of gravity that has a repulsive/attractive force, depending on whether one is inside/outside of the extended horizon. The outcome is an accelerated expansion inside the extended horizon and a decelerated expansion outside of the extended horizon. The author will show that the expansion of the Universe will continue to persist to the infinity distance. In conclusion, the reason that dark energy exists lies intrinsically in the true nature of gravity.
