Yes, we would have more "wobble in our rotation", and I am sure we all no the dangers of that. So on top of the Earths gravity being dirupted we have the chance of being slung into the Sun (I think, correct me if I am wrong), sounds nice (Not). Well in the movie The Time Machine they show the moon blowing up, and a lot of the bits come crashing to the Earth destroying most of it. That is a good example of the dangers. What if we were pulled farther away from the Sun if the moons blows up. The Earth would have unstable climate shifts, the planet would enter a new Ice Age, just more intense then the last one.
