Query: "Information Paradox" and Schwarzschildian geodesics   We show that the "Information Paradox" follows from inappropriate
considerations on the geodesics of a Schwarzschildian manifold created by a
gravitating point-mass. In particular, we demonstrate that the geometric
differential equation which gives the radial coordinate as a function of the
angular coordinate of the geodesics does not represent fully all the
consequences following from the metric tensor. We remark that: i) it does not
yield the conditions characterizing the circular orbits; (this fact has been
ignored in the previous literature); ii) it "neglects" the space region in
which the radial coordinate is minor or equal to twice the mass of the
gravitating point (in suitable units of measure).
