With so many posting here that have no plurality of them that properly function, you included, no.
You simply cannot grasp the concept that open space is what everything in it moves through.
That means that every star and every gas cloud and everything else in a galaxy is moving through space, and also spinning (in the case of most galaxies) about a central axis.
That means that each arm of the galaxy, full of billions of stars and other galactic elements, are all moving around that axis. Our solar system, and the local stars near us, are all moving through space at a given velocity. It doesn't have to be relative to any fixed object, ya dingy tart.
