Query: 10 + 1 to 3 + 1 in an Early Universe with mutually BPS Intersecting
  Branes   We assume that the early universe is homogeneous, anisotropic, and is
dominated by the mutually BPS 22'55' intersecting branes of M theory. The
spatial directions are all taken to be toroidal. Using analytical and numerical
methods, we study the evolution of such an universe. We find that,
asymptotically, three spatial directions expand to infinity and the remaining
spatial directions reach stabilised values. Any stabilised values can be
obtained by a fine tuning of initial brane densities. We give a physical
description of the stabilisation mechanism. Also, from the perspective of four
dimensional spacetime, the effective four dimensional Newton's constant G_4 is
now time varying. Its time dependence will follow from explicit solutions. We
find in the present case that, asymptotically, G_4 exhibits characteristic log
periodic oscillations.
