No thoughts of multiple bangs are required. THink of the shape of smoke tendrils from a cigarette. It starts out solid but breaks up into intertwining tendrils with 'empty' space between. One must also not forget that when discussing the big bang we are not discussing just the three spatial dimensions, because the 3d are the very thing that is expanding!!! The big ferment in this area is the which came first, the galaxies or the superclusters? Did the tendrils form by local gravitational attraction of galaxies or were inhomogenieties in the initial expansion responsible for supercluster size irregularities? I fear this is oversimplifying the arguments, but t'will serve and I'm too lazy to go pull a reference right now...
