The number of large dimensions enters into our
equations for E&M and gravity, among other things.
You would find with five or more large dimensions that
the fields of point masses or point charges no longer
fall off as 1/r^2. This obviously creates an empirical
difficulty. There are methods for getting around this,
but they require some more complicated setup, like
in the ADD or Randall-Sundrum pictures. As for time, it does factor in differently in everything,
since distances^2 in spacetime are not given by the
Pythagorean generalization x^2+y^2+z^2+t^2, but by
x^2+y^2+z^2-t^2. phobos
