So lets imagine a universe with only one object in it, right. We can't tell if the object is moving at all because we don't have anything to compare it to. If we have a two object universe though we can tell how fast objects are moving closer and farther from one another, but we still cannot determine speed, right? Speed depends on some kind of stationary object of reference. But even if we multiply the objects in our universe to a staggering degree the same is true. Speed cannot be determined without assuming an immobile object of reference.
Think of it like a bunch of flies buzzing around. You can always say fly A is moving toward fly B at such and such a rate, but you need to actually consider one of the flies completely immobile to judge the speed of any given fly. So, the question is 'what is the slowest speed?' In order to answer the question we need to address the elephant in the room which is 'what (if any of the objects in space) is truly immobile.
