We study the physical properties of the solutions and analyse the supergravity description of tachyon condensation. We construct an interpolation between the brane-antibrane solution and the Schwarzschild solution and discuss its possible application to the study of non-supersymmetric black holes.30 pages, Latex, 5 figures, Discussion of non-BPS D-instantons added, ref. addedHigh Energy Physics - Theorytext
