Also, re: lensing from ordinary matter: Dreaded Anomaly Send a noteboard - 29/04/2011 05:18:47 AM
The Wikipedia page on MACHOs (MAssive Compact Halo Objects) gives a good summary of the research into non-luminous ordinary matter as a dark matter candidate. It just about universally demonstrates that such objects can only account for a small fraction of all dark matter.

Cool, and true *NM* Stephen - 28/04/2011 11:46:29 AM 487 Views
I still think dark matter's just non-luminous matter without a convenient light source to reflect. Joel - 28/04/2011 10:34:21 PM 1095 Views
We've just about ruled out the idea that dark matter is just non-luminous "ordinary" matter. Dreaded Anomaly - 28/04/2011 11:44:34 PM 1033 Views
I'm aware of the Bullet Cluster, though admittedly not much more than that. Joel - 29/04/2011 01:52:49 AM 944 Views

Apologies for the delay; internet's been spotty and I've been busy lately. Joel - 10/06/2011 12:09:04 AM 1271 Views

Might help if you clarified where your skepticism is at Isaac - 29/04/2011 02:32:07 AM 901 Views
Potentially either, or a combination of the two. Joel - 30/04/2011 02:36:50 PM 974 Views
It's hard to discuss without knowing your objections a bit more clearly Isaac - 30/04/2011 04:58:03 PM 892 Views
My primary objection is that alternatives to dark matter seem to have been ruled out prematurely. Joel - 02/05/2011 01:29:14 AM 1087 Views
Well, they weren't, not really sure how else to put that Isaac - 10/05/2011 03:19:57 AM 1098 Views
Alright then, objection withdrawn (cautious skepticism intact). Joel - 14/05/2011 05:34:17 AM 1214 Views
