The world goes on forever, the horizon rolls back forever, the earth never rounds into a globe. Travel on and on, you’ll never come back to where you started from, which is not to say that your journey changes you or the time that your journey takes allows for great changes so that your point of departure will, on your return (having traveled for so long in the same direction and coming around the world) be unrecognizable to you. It’s to say that there’s always going to be more and the idea that the world was a single limited globe turns out to be a wildly unlikely mistake.
