You sound more like a philosopher now. I know it's cliché but, the more I learn, the more I see how little I know. It took me two years to grasp the meaning of mechanical torque only to find out that it really does not exist. All of our explanations are based on models and our models are not perfect. Can you imagine a body that must go through 720 degrees of rotation to return to its starting orientation? I'm beginning to come close. The real answer to your questions is "We don't really know." But, we have useful tools with our models! Terry
