I will persist.....
at the moment of the big bang..gravity was only a thought in the mind of God
the rotation had to be in play BEFORE the expansion began
Cause and efeect
And you have no evidence for this... In that case, what god? I put gravity there for everyone to enjoy and wonder about.
And it worked
No the rotation is the work of gravity
At a radius r1 from the galaxy's center, gravity is an attractive force because the energy density between the galaxy and a body (blue dot) exceeds that in the surrounding space. Hence, the body is subject to the acceleration, a, toward the center.

Note. Galaxies did to not begin to form until around a billion years after the BB
So does the universe rotate?
Does the Universe Rotate?
It seems not
