I would expect something kind of stretched out and warped like taffy. i.e. the front edge of the galaxy would be stretch out ahead of the back edge of the galaxy since the back edge is running behind time-wise.

> stretched out ahead

You have apparently not figured out (1) by how much? and (2) in which direction? - Andromeda rotates so slowly that after 220K years the far side has made only 1/1000th of a rotation. Please draw on a picture of Andromeda how far the far side moves after 1/1000th of a rotation. That's how small the image warping is.

Thank you. The "how much" is too small to stretch it out visually. Need a much larger spiral galaxy to see the effect I am thinking of.

Never forget that the universe does not have a "preferred scale" and has fractal complexity and emergent behavior from the smallest two particle interactions to the largest black holes circling each other.

Our 10 pound hunk of fat is not able to comprehend that.

A larger galaxy would rotate even slower. I don’t think this is a game you can win.
