Unlike more conventional views of creation in modern physics, that are ex nihilo, the M-Theory vision, although not yet complete, is of the whole observable universe being one of many extended 4 dimensional branes in an 11 dimensional spacetime.
Although branes similar to that representing our universe can co-exist in the theory, their physical laws could differ from our own, as could their number of dimensions. Some proponents of the theory now believe that a collision of two branes may have been responsible for the Big Bang (see Ekpyrotic).
