Hey, let's take the Moon out for a spin... but we're too late! It already does spin!

And I can prove it. Just watch Q & BA Episode 5: Spin Doctor and you'll see how.

The Question:

The question was sent in by Mark Tillotson, of Emmaus, PA:

What would we experience if the moon was not 'locked' in it's rotational period with the earth?

Would we see anything different on Earth? Would the tides be different? Would the lunar recession be different (moving away from Earth faster or slower)?

Images and Links

The essay I wrote about tides, the Moon's rotation/revolution lock, and its recession can be found on my Misconceptions page.

The lunar phases image is from the amazing Lunar and Planetary Observation and CCD imaging website of Antònio Cidadão; specifically, his animations page.

The far side of the Moon image is courtesy NASA and the Galileo probe.

I bookmarked the site with the revolver image so I could link it here, but I appear to have lost it (it was a public site, like from a museum or government). Oh well. Don't shoot me.
