> The oldest stars among those that we can see? Yes. If I've understood the lectures correctly, time isn't really well-ordered, and on scales like this the deviation makes a substantial difference. However, what we are looking at in cases like this is stars far enough away that the light took most of the age of the universe to reach us, so it's not unreasonable to call those stars (members of the set of) "the Universe’s First Stars". |
