> In other words, we end up with an entropy gradient that points along the TIME axis because the volume of space expands along that axis.

That's a good insight, I hadn't thought of it that way.

> I guess another thing to remember is that TIME and space really are different things. For example, conservation of angular momentum means the universe has constant angular momentum at all times, but not necessarily in all directions of space.

Yes, I realize they are different, but I feel like the issue is more that don't understand the relationship between the special properties of TIME and those of time.
