The Importance of Understanding Gravity

The buzzword is anti gravity, isn't it? It seems like once we have that to our veil, we won't need roads and supposedly we won’t need the fuels we use. There's an understanding of gravity that is, let's say, a misunderstanding. So in essence, if we're moving from a high altitude to a low altitude,gravity is pulling us down. Once this is understood, where we just decrease resistance on one end and increase resistance on the other, then you can do anything.
