A Five Dimensional Cosmological Model With A Fifth Dimension as
Fundamental as Time    [PDF]

Gizem Şengör, Metin Arık

In five dimensional cosmological models, the convention is to include the fifth dimension in a way similar to the other space dimensions. In this work we attempt to introduce the fifth dimension in a way that a time dimension would be introduced. With such an internal space, we are able to obtain accelerated expansion without introducing dark energy. Moreover our work shows that all relevant cosmologies in four dimensions can be embedded in a flat cosmology in five dimensions.
