It’s hard to get a sense that we’re standing on a sphere hurtling through space and spinning rapidly around a central axis. I know it’s true but looking up at the sky, I mostly imagine a bowl slowly rotating over my head.
But on a summer night, particularly out here in the West, and back east on one of the many back bays along the shore, looking out at the summer sky and seeing the Milky Way swing across the meridian, it’s pretty easy to see the Earth as it truly is; a small rocky planet in a nondescript arm of an average galaxy.
Here’s a video that gives a sense of what that experience is like if you haven’t had it yet…
