We then compactify M-theory on a warped product of homogeneous spaces of constant curvature, and construct a minisuperspace of scale factors. First classical behaviour of the minisuperspace system is analysed, and then a quantum theory is constructed. It turns out that there similarities with the "pre-Big Bang" scenario in String Theory.35 pages, 2 figures, added additional discussion of gauge fixing and self-adjointness of the Hamiltonian, added referencesHigh Energy Physics - Theorytext
