Query: The Accelerating Expansion of the Universe and Torsion Energy   In the present work, it is shown that the problem of the accelerating
expansion of the Universe can be directly solved by applying Einstein
geometrization philosophy in a wider geometry. The geometric structure used to
fulfil the aim of the work is a version of Absolute Parallelism geometry in
which curvature and torsion are simultaneously non vanishing objects. It is
shown that, while the energy corresponding to the curvature of space- time
gives rise to an attractive force, the energy corresponding to the torsion
indicates the presence of a repulsive force. A fine tuning parameter can be
adjusted to give the observed phenomena.
