摘要：

In this paper, as a toy model, we study the dynamics of a 5D bulk space-time with our universe as a "test 3-brane" located in the bulk; an idealized model of a topological object whose physical properties are negligible in comparison with those of the bulk. We obtain the result that our universe experiences acceleration and phantom crossing as a result of the geometry of bulk space time.
