Everywhere.
And all motion is relative. That means it only makes sense to say something is moving w.r.t something else.
Acceleration, however, is absolute.

pick a atom out & try2follow it - its kinda fun !...Brownian Motion
...i slowed it down some...here:
...tho now it looks kinda choppy - o well.
no apology necessary.
if something is random, say like the stars, how did they decide the distances?
factually or theoretically?
It is a philosophical question whether the question of whether the Universe is finite is a scientific question or not!
The reason is that while it is conceivable that it could be experimentally determined that the Universe is finite, it is inconceivable that it could be determined that it is infinite in a finite time. So at any time the most you can know is that the Universe is "bigger than X". Thus as a hypothesis it could never be checked.
However, a counterargument is that there are many scientific hypotheses that are only ever checked in one direction. Eg the hypothesis that the fine structure constant is constant can never be proven. Rather it just gets failed to be disproven. So the hypothesis that the Universe is infinite can have that status - consistent with the evidence and never disproven.

If the arrangement of your living room is random, how can you measure distances?
Your question makes no sense. The distance to relatively near stars is determined by the surveyor's technique of triangulation. And it works well.
It was a response to me posting the fact that quantum physics disproves determinacy in our Universe. Check the record if you wish. (I was able to edit my last post after being blocked).
If the earth is actually not moving anywhere ........... where is randomness then?
