An object in motion will always be headed in the wrong direction. For every action, there is an equal and opposite criticism. Doppler effect is the tendency of stupid ideas to seem smarter when you come at them rapidly. Physicists do it a quantum at a time. Physicists do it at the speed of light.
Cosmologists do it in the first three minutes.
Mathematical physicists understand the theory of how to do it, but have difficulty obtaining practical results. Quantum physicists can either know how fast they do it, or where they do it, but not both. Particle physicists do it energetically. Particle physicists to it with charm. Aerodynamicists do it in drag.
