RE: How are Dark Mtter and Consciousness different from Spirit?

Ahat we know about dark matter:
http://www.astro.ucla.edu/~wright/neutrinos.html Wrote:D = \int (1+z) v dt = 2(c/Ho) sqrt(3*k*(1.947 K))/mc2) + ...
which gives D = 100 Mpc for mc2 = 5 eV in a critical density model with Ho = 65. Thus neutrinos can free stream out of the perturbations that make galaxies and cluster of galaxies, but will remain in the perturbations that make superclusters. Because this behavior is caused by the thermal velocity of the neutrinos, this form of dark matter is called Hot Dark Matter
If we have an exact formula for how neutrinos interact to create different forms of dark matter then it's not much of a big mystery. This gives us a stronger argument than "It exists because we would have a problem if it didn't."
The god who allows children to be raped out of respect for the free will choice of the rapist, but punishes gay men for engaging in mutually consensual sex couldn't possibly be responsible for an intelligently designed universe.

I'm going to let Alex comment on this because he's far more qualified than I to do so.

Well, we know how neutrinos behave and that they are relatively "hot" dark matter, and therefore can only make up a small part of the total dark matter. The question that remains is what kind of particle the cold majority of the rark matter is made of.

If hdm is made up of something we can detect, then it's not unreasonable to suspect that cdm is too. Whish is what you guys have been saying. Yikes.

Since it's my job, I should know something about it, right... Who's a genius, now that's a different story

There are probably some that are low Energy enough to classify as cold... the exact masses of all three neutrinos are not yet known either, but they must be all very light, and most processes where they are created give them lots of energy and they move at close to the speed of light. Hot btw means just a few degrees above absolute zero in this case

Question is this” how is it that we give serious scientific consideration to the possibility of the existence of dark matter, and consciousness but dismiss the possibility of spirit when evidence for all these is based on the same thing.
The difference is that the rich body of physical observations and explanations we call science needs dark matter-- it is the best explanation for things we can actually observe. As for spirit-- well, it's not really a necessary piece in any part of the puzzle.

You'd hope so. 
If I'm not mistaken pocaracas is also a professional physicist.
The majority of what I know about physics has been from reading. That is to say, not much. A lot of it goes over my head. I read Guth's book on inflation - that went way over my head.

Yep, pocaracas is the resident experimental wizard who plays with fusion reactors. I'm a theorist, I haven't touched a wire or soldering iron professionally for 15 years
