Reply to comment by nicuramar in If you could instantaneously place a space telescope at any desired distance (LYs), from any planet/galaxy etc., where would it be and what would you be documenting? And for what purpose? by kennyarsen
You and OP are still wrong, and I am not arguing semantics. There are two things I corrected with my original comment, and they are not interchangeable.
The OP said the speed of expansion is different for something farther away. That is just plain wrong. The speed of expansion does not change just because something is farther away.
The correct thing to say would be the velocity (observation) of a distant object is faster than a closer object. That is what I said to OP in my original comment.
The rate or speed of expansion is the same no matter the distance.
A more distant object's velocity is faster than a closer object.
The velocity of a distant object is not the same thing as rate of expansion.
Velocity increases with distance, but the rate/speed of expansion stays the same.

I’m not OP or defending their views. I am just saying that expansion is stated as a rate, and doesn’t have units of velocity. I know how expansion works, and I wasn’t talking about that. You don’t need to keep explaining it, at least not for my sake :)
