You may have heard physicists describe the moon as being 1.3 light-seconds away, or the sun as 8 light-minutes away, and thought “what is this nonsense? Measuring distances with time?” But actually, we measure distances using time almost every day. How far is it from your house to the store? About ten minutes. And how far is it from New York to Boston? About four hours. Los Angeles to Sydney? 14 hours. But of course, what we really mean is that the store is ten bike-minutes from your house, New York is 4 car-hours from Boston, and Sydney is 14 plane-hours from LA. In fact, using time to measure distances is so useful that I only know the distance from LA to Sydney in plane-hours, not miles or kilometersâ€¦ though I suppose I could figure it out by multiplying 14 plane-hours by the 550-miles-per-hour speed of a plane to get roughly 7500 miles.
But Sydney is also 5 sailboat-weeks from LA, 7 humpback-whale months from LA, 5 message-in-a-bottle years from LA, and point 0.04 light-seconds from LA. On the other hand, the moon is 18 airplane-days away, 6 car-months away, and 15 whale-years away. Which means, in fact, that a whale might swim as far as the distance to the moon over the course of its lifetime. And if that’s not crazy enough, sometimes we even measure times in distance! How long is a movie? 8,000 feet â€“ of film! And MinutePhysics? 30 meters.
