Abstract : It is shon that if the Einstein field equations of general relativity are derived from a homogeneous variational principle, then the dynamical processes of the space are intrinsically reversible. As an application, it is shown that an isolated world tube of perfect fluid contains a geodesic stream line, provided the field equations are derived from a variational principle. (Author)
