Okay, if you like. What's the point of this quibble? The only term available for the phenomenon is "dark matter." There's no other. If they eventually find out that the explanation is not a form of matter but, say, modified gravity waves, then the problem that they'll say was solved is "dark matter."
The point of the quibble, is that you thought everybody had a wrong understanding of the term dark matter (you stated this multiple times) and that this is what was making the discussion between tesla and Taq difficult. The point is that you were wrong, and that the term was correctly understood as including only solutions that posited some form of matter as an explanation.
I'm not sure why the quibbling over terminology. Tesla claimed that alternative ideas weren't being considered for dark matter. If you want to claim that dark matter can only refer to solutions that involve matter then of course you are right because by your definition the consideration of alternative ideas is ruled out, but the fact of the matter is that alternative ideas are most definitely receiving attention. They're even described in the Wikipedia article on dark matter that you referenced.
No, I am right because this is how the term is universally understood in and out of the scientific community.
And I never claimed alternative ideas were ruled out, just that this was an example of the power of a paradigm.

Re: Not so fast....
Who is playing word games now?
I'm just saying that the concepts of hypothesis and eduacted guess seem to be no different except from the fact hypothesis is used when relating to science. And in that case saying a hypothesis is an educated guess is acceptable IMO.
I am 37 years old. Once I was just 6 months old. At one time I was a baby. Does that mean I am still a baby?
You did notice I used the past tense right ? I said it WAS and educated guess.
SO yes, it does mean you WERE a baby.

The scientists pursuing alternatives to dark matter don't seem to think that it is that essential. So unless you have some actual evidence...
http://www.desy.de/...Physics/Relativity/GR/dark_matter.html
Explains it pretty well in layman terms.
That's not about the Big Bang, it's about the age of the universe.
The age of the universe comes directly from the Big Bang model. Any evidence against the theoretical age derived from a BB model is evidence against this BB model
I'd say that it stopped them from arguing that the universe had to be young because the galaxies would have flown apart by now. But OK, if you think that they would go on saying that I'll believe you. Even so, a ready answer makes the argument less effective.
Except that they never made the argument that the speed of the galaxies was evidence the earth was young. Even some creationist cosmologies have galaxies living millions of years in their reference frame so if they ever used that argument, it would sort of backfire.
The closest I can think of is the argument (not often used, mind you) that the galaxies must be young because the arms would have spiraled much more then they have. But that's not what we're talking about here
You want an example ? How about the C14 in coal argument. Don't you think that if YECs were aware of the possibility of "finding" something just because they were desperately searching, they would be more worried about the possibility that the trace amounts found were contamination ? Or the "moon dust" argument, which would have found to be false by doing decent research ? Or the population argument ? Or the argument from short-period comets which causes YECs to suggest that the Oort cloud should be rejected ?
And don't bother getting on your high horse. You made the insinuations, is it somehow unfair that I turn them around ? And if you make a false assertion in the defence of creationists, am I not permitted to refute it ?
What I think is bad debate is the fact that you did not refute it, you simply asserted that they used it (the see-what-you-wanna-see phenomenon) as an excuse for being hypocrites without any basis.
There was nothing negative about what I said about evolutionists when they approach the evidence. I did not insinuate anything, I directly stated that this phenomenon applied to equally to everyone, including evolutionists and creationists.
If you want a forum where creationists - and only creationists - are protected against criticism this isn't the place for you. Admin does not want that sort of bias written into the rules. Criticisms of both sides are equally permitted. So if you want to make your insinuations then you have to be prepared to have them turned back on you.
Except that the only person who insinuated anything was you: you insinuated that the only reason creationists were more verbal about this phenomenon was so that they could use it as an excuse for being hypocrites.
Avoid any form of misrepresentation is a forum guideline

So you've got an article last updated in 1993 which seems to only use Big Bang theory to estimate the amount of baryonic matter in the universe. It's not clear how essential this is to the theory, so it doesn't really support your claim. More interestingly, even if it did you would be put into the position of arguing against the existence of baryonic dark matter, which hasn't really been discussed here or arguing that there was too much of it. So it really isn't that helpful to you.
The article points out that to produce the universe we observe, the Big Bang would have to produce a certain amount of matter. Since visible Baryonic matter only represents a small percentage of that amount, it is assumed the discrepency is solved by dark matter.
But if dark matter turns out not to exist, or not in such a large quantity, then the current Big Bang model would be falsified and require significant revision.
I guess you didn't understand the quote then. And why should they be reluctant to argue against some creationist cosmologies in favour of a result that suits them far more ? Evidence of a young universe is more use to them than explaining away the evidence of age.
You are misrepresenting their intentions, it has nothing to do with what ''suits them'' or doesn't.
That is pretty misleading. You were the one who claimed that creationists were more aware of the alleged phenomenon. I simply pointed out that they did not seem to apply that awareness in their own work. The conclusion of hypocrisy requires both to be true. And while we're talking about evidence, I have now at least referred to evidence that creationists do not employ solid quality control in their work - the arguments are well enough known that I don't think any more is needed. You've provided none for your assertions at all.
This is what I said:
quote:
This phenomenon applies to everyone, there are no exceptions. And it does not apply more or less to creationists. The only difference, is that it seems to be that creationists at least are more aware of it.
I clearly stated that it does not apply less to creationists. In other words, I would certainly expect examples where this has been the case from creationist.
More accurately you seemed upset when I pointed out that it applied to creationists and tried to imply that they handled it better. But producing no evidence at all, even now.
Obviously, if I acknowledged from the unset that it applied to creationist just as well, this cannot be the source of me being upset (in any case, it was more of a general rant then anything specific to this one discussion)

Re: Not so fast....
You want me to explain it again? Why? It was all there in simple English in my Message 80 that you replied to. You managed to quote almost the only part of the message that wasn't part of that explanation.
I did read your message, but it does not contain the answer to this specific quesiton, simply because it contains an example of an educated guess (predicting where your wife will be) and a fact (looking on the gps), but it failed to highlight the supposed substantial distinction between eduacted guess and hypothesis.
Anyway, one more time, but more briefly and forcefully, no English speaking person in their right mind would ever call a belief that a pot on the stove would boil as an educated guess or a hypothesis. That you used this example means you seriously misunderstand both terms, which are not synonyms anyway.
I used that example for the purpose of simplicity: putting a pot on the stove is frequently used example to represent ''the Scientific Experiment''.
Why are you trying to denigrate "hypothesis" by defining it as an educated guess? Is it that you want to be able to say something like, "A hypothesis is just an educated guess, so when scientists are hypothesizing they're really just guessing."
I repeated many times that saying a hypothesis is an educated guess isn't a negative thing, so I am not tryign to denigrate anything.
But the truth is, when faced with an unknown phenomenon in his lab, the scientist will use his knowledge to propose a tentative explanation for the phenomenon. There is nothing wrong with calling this an educated guess, even though in science it is referred to as a hypothesis.
In no way am I saying this just to say ''scientists are just guessing''.
My advice is to figure out what you're trying to say in terms that you and your opponents both understand in the same way, then express yourself in those terms as clearly as possible. Quit playing word definition games.
And the best way to do this, is to use the terms in the way they are defined by the dictionnary. This is much more efficient then both having the same, but wrong, definitions.
This is exactly what happened with the 'dark matter' quibble. You defined it in such a way that it included modified laws of physics and effects of extra dimensions, when it clearly was not how it was defined by anyone else, especially in the scientific community. When I pointed out that you were wrong to defined it in such a misleading way, you responded to me with ''if you like'', instead of simply saying ''Ok I was wrong''.
