If you stilled the Universe of rotation , where would gravity exist ?

Everywhere. As long as you have any mass, you have a gravity source, and the range of gravity is infinite.
What does that mean?
No movement .
Why mention rotation, then? Just say "if you stilled the universe..." or perhaps "Would gravity still exist if all the matter in the universe was at rest?". To which the answer might be "Why wouldn't gravity still exist, since gravity only requires mass, not movement?" On the other hand, when you're dealing with fantasy scenarios, I guess you're free to fantasise anything you like.
Within the mass , atomically, is rotation and vibration . Now still this , even in the quantum .
Where is gravity ?
In the geometry of space-time.
You might be trying too hard. Here, I'll try too hard in the other direction: I can't quite explain the detail of what anyone else thinks, but it is easy to develop a colloquial sense of rotation in the universe, whether it is a spinning galaxy, a movie or video game depiction of some sort of gravitational anomaly, or even animations of atoms with electrons orbiting a nucleus in an orderly, circular manner. I definitely overthought that. But what occurs to me in that moment is that the answer might be that if you still the universe it ceases to exist. At this point we start parsing terms, such as what constitutes movement or motion or as a question compared to rest. Atomic structure, for instance; the words we use imply a context of motion, movement, or activity that is not rest. Even if the idea of electron "orbit" does not imply kinetic motion, it is not rest. Accounting for the errors of colloquy, while "rotation" might not be the appropriate word, the answer might be that if stilled, the universe itself would not exist.
Where does mass fit into that geometry?
Gravity does not depend on rotation.
An anuther fun fact river... if the moon didnt rotate all of its surface coud be seen from earth.!!!
Mass determines how much the geometry deviates from the Euclidean ideal.
Stopping all motion? That would mean you'd have to bring the entire universe to a temperature of absolute zero, something that's not possible. AND has almost nothing to do with gravity, either.
(Next up - "if you took away social media, would electrons still exist?")
Am I right to say that the mechanism whereby this occurs is unknown for now?
