A new spin on the earth's rotation. Welcome to the tropics of Alaska. The sand dunes of Siberia, imagine a shift in the earth so profound that it could force the entire planet to spin on its side. A new report from a Princeton Geoscience team gives us the first real evidence that this kind of major shift happened some 800 million years ago. This theory is called true polar wander. It said that if an object of sufficient weight such as a supersized volcano ever formed, far from the equator, the planet would tilt and rotate itself until the extra weight was located at the equator. Although it's unlikely to occur any time soon, they say it could happen again before you pack your beach blankets. For Alaska. Know that a shift like this would take some five million to 20 million years.
