The cute little pinpricks of light you see out there are other giant, explosive, incredibly pissed-off balls of gas floating in an infinite void, most of which are far more impressive than our puny sun. And that smear of milky white through the sky? That's the center of our own galaxy -- a gigantic pinwheel circling a supermassive black hole like floating detritus around the vortex of a flushing toilet.
