He says that the aberration of light proves that the earth moves. (Remember the analogy of having to hold an umbrella tilted forward while walking throught the rain, because the rain appears to come down at an angle to the vertical?) He says that the amount of the aberration is due entirely to the linear speed. If the stars are stationary, and the earth moving, the angle of the aberration is the same for all stars. If the earth were stationary and the stars moving round it, their angular velocities would all be the same, but their linear velocities would be different, because of their different distances. This would mean that the aberration of light would be different for different stars, depending on their distance. I need hardly tell you, that the aberration of light is the same for all stars!
