One of the theories of for the origin of the Big Bang is that within The Bulk two branes touched, setting off the Big Bang. Where does that leave our universe or multiverse of which we are one of the 10^500? Are we contained in one of the branes while another wholly separate universe or multiverse is perhaps within the other brane? Or is our universe/multiverse now existing between the two branes and not a part of either? Or is there a connection to one or both branes?
