It's also cosmology, but for what it's worth, the solar system is moving at about 230km/s around the milky way so you could say every one of us is moving at such a number.
And then it gets weirder when you consider that galaxies don't actually collide at all because they're so sparse and all that really happens is they pass through each other and maybe they permanently merge or maybe some of the matter in one galaxy joins the other one and they just keep drifting apart in slightly different directions.
