The best analogy I've seen is imagine our universe as the surface of a balloon. Only the surface, we can't see or touch anything else.

If you inflate the balloon, our universe expands. Points get farther away from each other, proportionally to how far away they started. In this analogy, we're not expanding into anything we can see or feel or know anything about, the only real difference is that points are a bit farther apart.

This explains why there is no "epicenter to speak of", but why is that expansion faster than the speed of light? How could it be? And is the evidence for that expansion really that solid?

Because it's space expanding, not something moving inside of space. It doesn't follow the same rules.

[Bradley_A_Pliam]

I find this to be the crux of the issue. To be exempt from the rules that material things must follow, you simply need to designate it as space.

If space is what fills an area between object A and object B and that space grows or expands. This is no different than object A moving away from object B. What's the difference? There seems to be none.
