Dadhich, NareshPatel, L.K.2015-01-272015-01-272015-01-27http://hdl.handle.net/11007/2828For orthogonal cylindrically symmetric expanding perfect fluid spacetime we prove that vanishing of shear implies vanishing of acceleration which further renders spacetime homogeneous. That means inhomogeneous spacetimes must always be shearing and anisotropic. Non-singular spacetimes will thus be both inhomogeneous and anisotropic.enFluid modelArticle
