I bought a gyroscope at the NASA Space station in Houston when I was in 5th grade. Granted it was a toy, but it had a string that you put through a hole and you would wrap it around the axis. When you pulled the string the center began to spin making the gyroscope stand upright like a top would.
This is a perfect example of how the center of the Earth works. By the center spinning, the outside spins as well. This is a great example of how gravity works: A central force pulling objects to the center creates gravity and with the Earth's atmosphere spinning the opposite direction, stabilizes it.
Earth's Electromagnetic field is the reason we have storms and why all objects on Earth are charged either negatively or positively.

And all you FE'ers out there, you can debate me all you want, you are entitled to your own theory. I'm just simply saying that according to RE theory, that explains why gyroscopes are important and how gravity works in this model.
