Methuselah star is confusing, but really really old....


There is a star floating around out there that appears to be really really old... like older than the whole universe.  Wait a minute... how can it be older than the universe?  Something must be wrong.  According to the original estimates, the star was about 16 billion years old, while the universe is only 13.7 billion.  Well, in fact, it appears that the star, named HD140283 (or Methuselah, depending on who you ask) is travelling very very fast, and was created very soon after the universe was created (not before the universe existed as originally estimated).  Watch the video to get the whole story.
