So there has been talk in the news of a star named Methuselah that is "older than the universe". Moreover, this star happens to belong to our very own Milky Way.
I must admit that I only have a modicum of familiarity with stellar evolution, and so these incredible headlines have left me strapped with questions:
- How reliable is this research?
- What method do they use to measure the age of such a star as Methuselah?
- Which is more likely to be wrong, the age of Methuselah or the current estimate of the age of the universe?
- Could relativistic effects account for some of the age?
