Re: Apologies for the delay; internet's been spotty and I've been busy lately. Dreaded Anomaly Send a noteboard - 14/06/2011 03:38:18 AM
That's a valid and important distinction, but it still seems that anything that can't be examined is mere speculation rather than actual science. Otherwise anything from Flying Spaghetti Monsters to magic becomes a sound scientific hypothesis if it doesn't conflict with known facts and one simply dismisses the absence of confirming evidence as human and/or mechanical inadequacy. Pseudoscience subsists entirely by applying that logic to anecdotal evidence that defies controlled experiments, but I doubt your intent is to put dark matter in the same class as ESP and astral projection.


As I said, if we don't have a way to test a theory, we have to put it on the backburner. Pseudoscience often does make itself unfalsifiable by "explaining away" the results of any contradictory experiment, so the comparison isn't really apt.

It's a Boolean equation; either baryons are conserved or they aren't. However uncommon or unlikely their natural decay, if it occurs it occurs, and violating conservation of baryon number ceases to be an obstacle to MACHOs as well as to the various Pati-Salam alternative GUTs. It disqualifies both or neither.


That is false. We know that lepton number isn't actually conserved because neutrinos oscillate, but the leading-order interactions and decay processes still tend to conserve lepton number. The low frequency of neutrino oscillation suppresses the processes that violate lepton number conservation. An analogous situation may well exist for baryon number if that conservation is also violated. If processes which don't conserve baryon number are suppressed for any number of reasons, the simple fact that the violation occurs would not necessarily lend any support to MACHOs.

It's also wrecks credibility with perceptions of The Scientist Who Cried, "Wolf". Slow and steady wins the race, to conflate fables.


Most of the time, the people doing the wolf-crying are journalists, not scientists.

Also, the lesson most people take from that fable isn't a very good one. Slow and steady may beat quick and impulsive, but quick and steady is still better than either.

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 966 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 909 Views

Might help if you clarified where your skepticism is at Isaac - 29/04/2011 02:32:07 AM 790 Views
Potentially either, or a combination of the two. Joel - 30/04/2011 02:36:50 PM 871 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 948 Views
Well, they weren't, not really sure how else to put that Isaac - 10/05/2011 03:19:57 AM 965 Views
Alright then, objection withdrawn (cautious skepticism intact). Joel - 14/05/2011 05:34:17 AM 1098 Views
