Our day consists of 86,400 seconds, a number that strikingly mirrors the Sun’s approximate diameter of 864,000 miles when scaled down by a factor of 10. Imagine if we designed our time system around our orbit around the Sun, assigning one second for every mile of the Sun’s diameter. This offers us a logical way to think about how natural measurements could inform our units of time. In this view, the structure of our day might reflect a deeper harmony between our planet’s movement and the dimensions of the star that sustains life on Earth.
