We present some exact solutions of the Einstein equations with an anisotropicfluid exploiting the Chaplygin equation of state. The solutions describespacetimes with two identical T regions and an intermediate static sphericallysymmetric R region containing a wormhole. The metric in the T region representsan anisotropic Kantowski-Sachs cosmological model. Its evolution starts from anevent horizon and develops according to different scenarios including eternalexpansion, contraction and also a finite universe lifetime.
