Why use a Rocket?
Debunkers say why use a rocket at all? What does it show? It shows the same thing gravity shows. It uses force to accelerate a mass giving it energy. But a rocket uses measurable energy. The only question is whether to combine force with distance or time. In the past, physicists have been combining force with distance and getting an erroneous concept of energy. When force is combined with time, it produces a correct definition of energy. Debunkers will say that the combination of force and distance is work, not energy. But it equals energy for an accelerating mass (by the erroneous definition of energy). In fact, at the level of real science, energy is more often measured (supposedly) as force times distance than mv, because it’s easier. Conservation is the Test The test of energy (and momentum) in physics has always been “that which is conserved.” In physics, the concept of conservation is always clear. It means component elements can be rearranged, and totals stay the same. It also m
