The understanding that gets me through the night is that time itself does not tug – more that spacetime is not the steady, linear stream it is imagined to be, and instead itself a never-ending and lush terrain full of gravitic features to explore. The satellite is at the exact position in spacetime it is supposed to be. But when, exactly, by a human standard, is that, so that we all may wind our watches appropriately? Well, as we can see from this story, that’s always a bit negotiable.
