You didnt quite get my point, I meant on the grand scheme of things they are the same for the following reasons
Theory 1 - Cold Dark matter being WIMPs - Can explain the structures we see, can explain the galactic rotation curves that we see, can explain large
scale lensing effects that we see. Some models in particle physics predicts the possibility of a high mass particle that is stable and weakly
Drawback - Next to impossible to detect
Common criticisms "You guys are making this up as you go along, its too complicated to explain this"
Particle physics? huh whats that got to do with anything those guys are talking out of their asses. I will ignore the fact that the Standard Model is
the development of our theory of all particle interactions developed over 40-50 years oh and can predict many many many many observables and get them
right... Oh it possibly predicts a possible dark matter candidate,,, haha that has no basis at all. *sarcasm*
Theory 2 - Dark matter is some kind of reflection of an alternate universe held in a different dimension.
Drawback - While beautifully elegant, can it be proven? Well best of my knowledge, no, why? well rotation curves if it is just regular matter in an
extra dimension, it has to be dispersed differently. For it to be dispersed differently and for it to still be 'normal' matter then in that other
dimension physical forces have to be different. SOoooo you just invented a whole other universe and physics, that has less chance than theory 1 to be
The point being.... unless we can prove any of it, then both theories are simply words on a page. We have more chance of proving one of them to be
true, or not... so why not go for that one??? Why do people have to have a constant criticism of scientists who are at least trying to answer these
If you think that you should just accept the extra dimensions model, then well done, you just accepted something with very very very low physical
evidence, cannot be proven directly and essensially is a nice way of glossing over a subject.
I dont mean to say that WIMPS are the only possibility, absolutely not, there are others, but right now, this fits our theories better than most else,
so why is it a bad thing to pursue the theory? Pursue the model, spend a small amount of money to advance knowledge, develop detector technology,
possibly develop some nice technology along the way? Isn't that better than just sitting around and saying "oh dont worry about this enormous problem,
its just an extra dimension" Or "Oh... god did it"... science right now is trying under very difficult circumstances (financial) to answer these
questions and it will at all times try and explain these problems, and any answers we may find to the world.
Sorry if this might seem insulting but, it really is not my intent, nor how i wish it to sound but, the general population knows a minimal amount
about the real ins and outs of science, not because of some big cover up, but because, the people who are thinking seriously and devoting their lives
to finding these answers are not funded very well, and the general public have an attitude that is "Complicated, im bored, tits, antigravity or some
sci-fi ray gun or STFU". When people, such as many here on ATS want to discuss these things, theories and what not, they do so very much in the manner
of a hard man in a bar. Except rather than using muscles, (or brain power) they use as many complicated buzzwords as possible, like each buzzword is a
punch and unless people can construct a come back with more buzzwords, then they have lost...
I do welcome all possible theories to what dark matter and dark energy is, I find the whole subject absolutely fascinating (i should do lol im in the
wrong field if i didn't) and I too am not totally sold on the idea of WIMPS, but as i said, its the best bet we have at the moment. If we find it is
something else, then great, more things to search for.
Let me ask this... Say you loose your car keys, you have this idea that they might be behind the sofa... were do you look first? Do you go outside,
walk 5 miles dig a hole 6 ft deep and think... ooooh danm not here, then carry on digging? no you think, well the best possibility is the sofa, so you
check that first... if that doesnt turn up anything, you think about when you last saw them. etc etc etc
That is what science does, it does not take random stabs in the dark... even if 'people' think thats what we do, it really doesn't.
