If I'm not mistaken, we're part of the giant cloud of dust and stars just an handful of light years behind this house. So long as you can fit at least 25000 light years in your hand, as that's how far it is to the center according to a quick google search. Wikipedia says "The Galaxy rotates differentially, faster towards the center and slower towards the outer edge. The rotational period is about 200 million years at the position of the Sun. The Galaxy as a whole is moving at a velocity of 552 to 630 km per second, depending on the relative frame of reference. It is estimated to be about 13.2 billion years old, nearly as old as the Universe." Spinning seems to be the most popular motion of the universe, or maybe it's just that it's the one that lasts the longest and/or is most easily observed. Even more interesting "The Milky Way is a barred spiral galaxy 100,000–120,000 light-years in diameter containing 200–400 billion stars. It may contain at least as many planets, with an estimated 10 billion of those orbiting in the habitable zone of their parent stars." And that's just one galaxy! Do you know how many galaxies are out there?!?! Neither do I, but I know there's probably more than I could possibly fathom. My brain isn't equipped to handle such giant numbers, and I'm not sure it ever will be.
