On Lasting

On Lasting reframes the measure of a life. We rank ourselves by reach — distance covered, ground gained — but the universe keeps a quieter ledger. Beginning from a "category error" (asking how many light-years old the Earth is), the essay finds the mistake wiser than it looks: out among the stars, distance and time are one, and to look far is to look back. In relativity everything moves through spacetime at a single fixed budget — the speed of light — so a nearly still world spends almost all of it on time. The Earth, going essentially nowhere across space, has therefore travelled four and a half billion light-years through duration — exactly far enough that the cosmos, gazing back, can still watch it being born. Deep time even has a colour: the redshift, light stretched warm by the long crossing. The achievement was never distance; it was duration. This realigned edition threads the author's own reckoning through the argument — his reflex toward reach, his consolation in stillness, his sense that this piece quietly corrects the rest of the series.
