Comments on: Globular Clusters Like to Be Near the Center of the Action http://www.universetoday.com/2008/08/05/globular-clusters-like-to-be-near-the-center-of-the-action/ Space and astronomy news Sat, 21 Nov 2009 21:17:24 -0600 http://wordpress.org/?v=2.8.6 hourly 1 By: Donna Greven http://www.universetoday.com/2008/08/05/globular-clusters-like-to-be-near-the-center-of-the-action/comment-page-1/#comment-29055 Donna Greven Sat, 09 Aug 2008 07:21:17 +0000 http://www.universetoday.com/?p=16495#comment-29055 Considering dark matter and energy. Could this not be the material and energy that happens between the time the light of any given object leaves that object and the time it reaches Earth? There can be an awful lot of time involved there and we could NEVER actually see it. Would any astronomers care to make a consideration of this idea and perhaps a study of it? I would like to see this idea expounded upon in future astronomy articles. Thank you. Considering dark matter and energy.

Greg,
If gravity can strip away the gas (tenuous?), why does it leave the heavy stuff in place?

Rather, the globular clusters tend to stay intact and are stolen by bigger galaxies from smaller galaxies. Kind of like a big bully stealing marbles from all the little kids. At least I think that's how it works... As I understand it, the globulars are not little pieces of a smashed galaxy left over from a gravitational disturbance by a big galaxy.

M87 likely grew so big as a result of many mergers. The globular clusters likely represent what is left of galaxies eaten by M87. The gas was stripped away and the clusters is what remains of these smaller galaxies. This is not at all surprising. M87 likely grew so big as a result of many mergers.
