The earth wobbles in space... and thanks to global positioning system (GPS) technologies, this wobble has been tracked with a precision of a few millimeters over the last decade... Geoff Blewitt, University of Nevada research geophysicist, has an explanation for this mysterious geo-wobble. "The theory, which my colleagues and I have proven using GPS observations of the Earth, is that it's likely to be caused by the surface matter being redistributed..." To make the Earth wobble, large amounts of mass need to be moved from one place to another so that the Earth is "off balance," according to NASA-funded researcher Blewitt, who said the North Pole then adjusts to a new position to compensate. Large amounts of water are displaced seasonally when glaciers and ice sheets melt in spring, for example. The mass shifts back when they refreeze in winter. "We measured the earth's shape directly," he said. "It agrees with the wobble. What our measurements are showing is that everything is consistent the earth is wobbling while it's changing its shape," he said. "The Earth isn't a perfect sphere," Blewitt noted. "It bulges at the equator because it's spinning. If the position and height of that bulge changes slightly even a few millimeters we can pick it up."

I'll tell my son. I'm sure he will be immensely happy by the news... ;o]
:’) Sounds like a cool new idea...
LOL!

Gee, I thought it was weebles making it wobble...
Perhaps, but they are definitely the reason Weebleopolis fell in ancient times.
But they don’t fall down.
