Abstract

In this study time-dependent and spherically symmetric solutions of the Einstein field equations in an anisotropic background with a purely radial tension are presented. There exist three classes of solutions: 1) an open space time with a WORMHOLE at its cent er. 2) A conical space time. 3) A closed space time. These inhomogeneous solutions are reduced to FRW space times in matter-dominated era, asymptotically. Therefore, they can be used to describe local in homogeneities that are not considered in the standard model. For the WORMHOLE solution, it is explicitly shown that the considered matter is non-exotic, that is, it does not violate the ENERGY CONDITIONS. Also, static solutions are studied. There is only one static solution: a conical space time. In this case, the matter satisfies the energy condition critically.
