If the local brane was connected to another, then the fold point—the crease—lay at a cosmological distance beyond even the Hubble length scale. But there was nothing to prevent matter and radiation making the journey around that fold, given time. If one travelled far enough along the surface of one of these connected branes—through countless megaparsecs, far enough through the conventional universe of matter and light—one would eventually end up on the next closest brane in the multidimensional void of the bulk.
