Watch the World Spin

Here’s an incredible video.  This guy used time-lapse photography to capture the movement of the night sky above Mauna Kea, Hawaii.  It’s beautiful, first of all, worth checking out on that merit alone.  But I think the real significance of this video is that it gives us a sense of our own movement.  It’s almost too easy to see the sky as a screen, with a moving starscape playing across it.  But if you can change your point of reference, and imagine the earth rotating under a static sky, it becomes a humbling and awesome experience.
