Origin of globular clusters

[maze]

Globular clusters have a few well known characteristics

• They contain only old stars
• All stars within a globular cluster are approximately the same age
• They contain very few heavy elements
• The heavier the supermassive black hole at the center of a galaxy, the more globular clusters orbit around that galaxy

 

Based on the above I speculate that globular clusters around the Milky Way were formed by gas emitted from the jets of the supermassive black hole at its center, by the time our galaxy was a quasar.

 

I've just had the thought this evening. Not that I would claim to be the first, it seems too easy of an idea to not have been proposed before.

 

Anyway, what would be your objections to this hypothetical origin, or maybe you do know some other clue(s) which would point towards the same interpretation of the above observations?
