Potentially either, or a combination of the two. Joel Send a noteboard - 30/04/2011 02:36:50 PM
IS it that you think the mass estimates are actually off or that they are right and we just can't see the otherwise normal matter? Because they're kinda separate for the purpose of producing supporting evidence.

What bothers me is that there seem to be several possible but largely unexplored alternatives to "well, that's dark matter irrefutably proven then". I'm reminded of that Laplace line paraphrased as extraordinary claims requiring extraordinary evidence; positing not just neutrinos but an entire new class of matter strikes me as something requiring a bit more evidence than one anomaly can provide. Particularly given many members of the group pressing that claim reject far older and less controversial claims possessing far more evidence.... :P

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 1181 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 1122 Views

Might help if you clarified where your skepticism is at Isaac - 29/04/2011 02:32:07 AM 984 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 1215 Views
Well, they weren't, not really sure how else to put that Isaac - 10/05/2011 03:19:57 AM 1218 Views
Alright then, objection withdrawn (cautious skepticism intact). Joel - 14/05/2011 05:34:17 AM 1327 Views
