Everything comes down to relative charge. That's why electricity is more powerful than gravity. Gravity doesn't move at the speed of light either. It's not instantaneous. Yet, if the sun's orbit shifted, the affects would be immediate. You cant make a logical argument for gravity, because it's based entirely on hypothetical theory. You cant identify the matter of gravity. It's there, but you can't see it. Just believe. That sounds like a religion, not science. We can measure the electricity that's all around us. Everything has a charge and we exist in an electromagnetic field. The exists in one, that's the Heliosphere. And so on an so forth. That's a fractal. The same from the smallest to the largest, changing only in scale. Which we can predict and measure that electricity is in fact scalable. And that we can prove with anything that produces electricity.
