\label{superslow} A spacetime diagram is shown for the journeys taken by the subluminal ships described in the text. Time is plotted against distance traveled, both measured in the frame of the Earth. Earth remains at $(0,0)$. The world line of the planet continually receding from the Earth at $v_p = 0.1 c$, in the Earth frame, is depicted by the dark dotted line on the right. A space ship traveling out at $v = 0.1 c$ in the Earth frame is shown by the light dotted line. This ship never reaches the planet. A ship traveling out at $v = 0.5 c$ in the Earth frame, reaching the planet, and returning to Earth at $v = 0.5 c$ in the planet's frame, is shown by the dashed line. A ship similarly traveling at $v = c$ is shown by the solid line.
