With inflation, the Big Bang theory takes on new meaning. When first conceived, the inflationary period was thought to have started at a particular point after the instant of the Big Bang. But once you accept inflation, there isn't necessarily a good reason to think that there was a normal expansion period before, if there was even was a "before inflation." In fact, the instant that inflation ended can perhaps be thought of as the moment that our universe as we know it came into being. In that sense, inflation is the initial kick of the Big Bang. We don't need to talk about an exploding singularity at all. Time may not have begun with the Big Bang.

on the largest scale, the universe does loop back on itself

on smaller scales it is a fractal-like mess of inflating regions and regions that stopped inflating, one of which is where our observable volume is located
