Hello,
I really need help answering this question.
I know when low mass stars die, they become white dwarfs (if their mass is less than 1.4M).
But I don't know why the end points in the life of low mass stars help astromomers to understand the expansion history of the universe.
How do they show anything about the universe expanding?
Please help!
Thanks
