All the old constellations had gone from the sky, however: that slow movement which is imperceptible in a hundred human lifetimes, had long since rearranged them in unfamiliar groupings. But the Milky Way, it seemed to me, was still the same tattered streamer of star-dust as of yore. (7.11)
Although the Time Traveller sees these changes, he realizes that they go beyond the personal perspective of time. (The Time Traveller may be pretty great, but he doesn't have "a hundred human lifetimes" saved up.) And yet, while this cosmic view goes beyond the personal, the Time Traveller also notes that some things haven't changed, like the Milky Way. Or perhaps that is merely wishful thinking, as he qualifies it with "it seemed to me."
