Parallel as in further "up" and "down" along some unperceived Nth-dimensional axis sorta thing, as I'm imagining it. We'd be some percentage of dark matter to every other "known universe", ourselves, in a cosmological principle sense, not particularly unique or special. If the gravitational force also falls off along such an axis, assumptions about what percentage each parallel universe consists of becomes more complicated. The nearer ones could be more massive than otherwise expected. Each successive parallel universe would also contribute a smaller amount to the whole.
