t = d / v

Earth to the Moon, at real speed.

A beam of light crosses the 384,400 km to the Moon in about 1.3 seconds — fast enough to watch, bouncing back and forth below in true, unsped-up time. NASA's Parker Solar Probe, a rifle bullet, and a jet airliner move at their real speed too, just far too slowly to see against that same distance, so the first 1,500 km near Earth is magnified underneath.

Distance is the Moon's average distance from Earth; light speed is 299,792 km/s in vacuum, giving t = d/v = 384,400 km ÷ 299,792 km/s = 1.28 s one-way. Parker Solar Probe's speed is its record closest-approach speed near the Sun, not one it reaches near Earth — treated here as our fastest machine, hypothetically let loose on this trip. The lower ruler is not a second trip: it is the first 1,500 km of the route above, magnified so the slower travellers can be seen moving at all. The speed control multiplies every clock equally; nothing is warped relative to anything else.
