Query: Deformation Retract and Folding of the 5D Schwarzchild Field   In this article we introduce some types of the deformtion retracts of the
$5D$ Schwarzchild space making use of Lagrangian equations. The retraction of
this space into itself and into geodesics has been presented. The relation
between folding and deformation retract of this space has been achieved. A
relation for energy conservation similar to the one obtained in four dimensions
has been obtained for the five dimensional case.
