Reply to comment by araujoms in Does space expansion occur uniformly in all directions and dimensions? by Tank_AT

I'm addressing expansion of space because that's the topic of the question. I am confused as to why you think I should answer a different question.

(Regardless, it would seem to me that the appropriate course for you would be to make a separate answer, rather than to falsely claim that the existing answer is incorrect!)

Because you are so emphatic in your answer that expansion is not a force that one gets the impression that no such force exists. For example, you quote > You shouldn’t think of galaxies as being pulled apart by some kind of expanding space

and > there is no local effect on particle dynamics from the global expansion of the universe: the tendency to separate is a kinematic initial condition, and once this is removed, all memory of the expansion is lost.

While both sentences are technically correct, a lay person will incorrectly conclude that no local repulsive force exists. I don't think this is good science communication.

That's a fair suggestion. I'll make sure to include mention of dark energy next time.
