We concentrate on a systematic analysis of the nature of the space-time in such domain wall backgrounds and the special role that supersymmetry is playing in determining the nature of such configurations.LaTeX2e using amtex, amssymb, epsfig, subfigure, and afterpage; 88 pages, 25 PostScript figures, reviewHigh Energy Physics - TheoryGeneral Relativity and Quantum CosmologyHigh Energy Physics - Phenomenologytext
