This is an interesting hypothesis that doesn't seem to have been discussed yet. What are its flaws?
Mark Hadley at the University of Warwick argues that galactic rotation causes gravitational frame-dragging sufficient to put a local asymmetric twist into spacetime and explain observed CP violations.
If the universe was "spinning" early in the big bang, this could also have been the original source of CP violation to create the necessary matter~antimatter imbalance.

Some might connect it to Longo's axis of evil...

It seems an elegantly simple explanation. I guess the whole early universe does not need to spin like a top (how can a boundaryless space rotate?) but there might be a fractal patchwork of spin orientations inside that added up to the needed total slight asymmetry.
So what is wrong with the idea? (And what are your favourite alternative explanations for a source of CP violation?)
