But in the dynamic space of the living Rocket, the double integral has a different meaning. To integrate here is to operate on a rate of change so that time falls away: change is stilled..."Meters per second" will integrate to "meters." The moving vehicle is frozen, in space, to become architecture, and timeless. It was never launched. It never did fall.
