The only problem with a rotating universe is that it would have to have a center.

Like a ferris wheel with the point of rotation being at the axis.

The universe was all "begun" at once, and is expanding...

That is... ALL of it is the center, the outside, and the inside. There is no part of our universe that started at a point in space and moved away from THAT point like an explosion. The point itself is growing.

Without a center, it cannot rotate around an axis. To have an axis, there has to be a center.

Can it churn and move around within itself? Sure... that's easy.


Here... take a glass of water and contemplate where the center of the water is without regard to the glass.

It is ALL water. The problem is the glass. We have no glass. Space itself only exists within the universe. Space and everything in it is the water.

It can't rotate, because no matter which way you look, you are looking back into TIME.... not a place. (on large scales)

Edit to add - try to find the center of the surface of a bubble.
