How old is the oldest star?
That is an interesting question. From what we know of the evolution of
stars (that is, how they change as they get older) there seem to be some
stars around that are roughly 15 billion years old. However, recent
measurements of the age of the universe suggest that the entire universe is
younger than that (maybe 10 billion years). The answer is probably some-
where between those two numbers.
