Query: Geometrization of Mass in General Relativity   In this paper we will extend the notion of tangent bundle to a $\z$ graded
tangent bundle. This graded bundle has a Lie algebroid structure and we can
develop notions semi-riemannian metrics, Levi-civita connection, and curvature,
on it. In case of space-times manifolds, even part of the tangent bundle is
related to space and time structures(gravity) and odd part is related to mass
distribution in space-time. In this structure, mass becomes part of the
geometry, and Einstein field equation can be reconstructed in a new simpler
form. The new field equation is purely geometric.
