Proponents of a static universe have a lot of explaining to do. For example, older galaxies tend to look lumpy and amorphous, because they interacted and collided with other galaxies more often in our early, dense universe. Symmetric elliptical galaxies and our structured Milky Way tend to be younger. Also, you can have a static universe with a beginning, or an expanding universe with no beginning. Rainbow gravity falls into this latter category.
