00:03not all stars are bound so neatly like our sun some are soaring through the universe more
00:08transient than even asteroids or comets which are still bound to the systems in which they orbit
00:12so where do these wandering stars come from well scientists have had many theories one of which
00:17involves massive galactic gravitational interactions which force stars out of their
00:21galaxies and into the cosmos but after tracking the light from these homeless stars back 10 billion
00:26years they found they've been on their own for at least that long meaning it must be something else
00:30james g one of the astronomers from the university of south korea who's working on figuring out where
00:35they come from had this to say about it we don't exactly know what made the stars homeless current
00:39theories cannot explain our results but somehow they were produced in large quantities in the early
00:44universe adding that in the early days of the universe smaller galaxies that formed likely
00:48didn't have strong enough gravitational pull leading to more stars being lost to intra-cluster space
00:53resulting in more light between galactic clusters still today
