So you're telling me that the spatial distance between objects in the universe is expanding at a rate faster than the fastest speed an object can travel in the universe meaning that light cannot even travel the whole distance of the universe ever because of the rate of expansion.

No no no.
It is like a balloon. And light expands with the balloon.

assuming the rate stays constant yes

I continue to maintain that if time expanded at a constant rate; a consequence would be the perception of an accelerating expansion of the physical universe

It is not physically possible for any object to move across the entire universe and explore both ends of the universe, or even most of the universe, because the universe itself is getting bigger and the distance between things is increasing faster than the fastest object can legally move in accordance with the physical laws.

The objects themselves aren't moving.
It's the space around them that moves.
And space can move faster than light.

Okay, so the balloon is expanding faster than the fastest thing permitted to move in it. So what's causing the balloon to inflate?
>Well, you see, we don't really know. So we call it dark energy
If you don't really know, then why the fuck are you so certain the speed of light is the maximum speed in the universe?

How can space move if all movement is defined against it? Is there some sort of meta-space that our space moves in reference to?

Correct; the speed of space is just a little faster than the speed of light.

Space is not expanding faster than light. Space is expanding much slower than light. Just because all of space is expanding, it doesn't make it faster than light.
Any one planck length is expanding at about $1.2-1.3*10^{-61}$ planck times per planck length, which happens to be 61 orders of magnitude smaller than c.

the further away, the faster that region of space is expanding away.

pseud detected. opinion ignored. there is no evidence to suggest that planck units have any physical significance whatsoever.

Based on faulty premise so also no

Space doesn't move. You are misunderstanding general relativity.
