Dancing with the Moon

Months are getting shorter. This is happening so slowly that you can’t really tell unless you use very precise measurements and careful observation, but it IS happening. Back when folks first started to look at the sky and try to keep track of the rate at which things happened, months were approximately 40 days long. Now, as I expect everyone knows, they’re about 28 days long.

The reason for this is the gravitational effect that our blue planet and its moon have on each other. The tides she creates on our surface are very gradually slowing down our rate of rotation. And the pull we exert on her is speeding up her orbit.

To which you’re saying, “So what? I didn’t come to the blog today for an astronomy lesson.” Well, okay, but keep listening.

You know how the moon always shows the same face to us? Her rotation has synchronized itself so that she always faces the center of her orbit. It turns out that that’s natural; any two objects in orbit around each other will eventually do that. They start off like they’re next to each other in a mosh pit, swinging around each other and spinning crazily and looking every-which-way, but little by little they come together and start doing a waltz, locked in an embrace, gazing into each other’s eyes. That waltz, and not the slam dance, is the natural order of things, the result towards which our mutual orbit is drawing us.

So someday, about 20,000 years from now, we will reach a point beyond which we will always show the same face to her, just as she does to us now. Which means that she will, from that moment on forever, hang always over the same spot on the Earth.

And what I’m thinking is this: I want to find out what spot that’s going to be. And then, when I know, I’m gonna move there. And if I happen not to live for 20,000 more years (‘cause, you know, accidents happen), then when I die, that’s where my remains are gonna be stored. Wherever she’s gonna be, I wanna be there, too.
