Another Problem With Big Bang?

4. Do not star clusters in the halo of galaxies show a rate of rotation that can not be accounted for by gravity minus dark matter? How does PC/PU explain them?


Well, here:
http://arxiv.org/PS_cache/astro-ph/pdf/0407/0407447v1.pdf

And here:

http://arxiv.org/abs/astro-ph/0402022

They are talking about the effects of galactic magnetic fields of about 1 microGauss.

The first reference says that's enough to eliminate the need for dark matter, while the second says:

Even though there is no doubt about the existence of
dark matter halos around galaxies, it is desirable to constrain
the magnetic effects on the Hi rotation curves for a
correct interpretation of the observations. It is suggested
that magnetic fields can contribute to produce wiggles in
the Hi rotation curves, which could be likely associated
with non-axisymmetric waves in the disk, as may be the
case of NGC 1560. However, the magnetic tension is unlikely
to produce substructure in the rotation curve of massive
spiral galaxies above 20 km s−1. In S´anchez-Salcedo
(1997), the detailed shape of the rotation curve of this
dwarf galaxy was fitted reasonably well combining a magnetic
field of strength ∼ 1 μG plus an isothermal dark
halo.

These guys have "no doubts" about the existance of dark matter apparently.
 
BeAChooser.
In another thread we were talking about A direct empirical proof of the existence of dark matter and you stated:
David and his friends on this forum like to go on and on about dark matter being directly "observed" in the case of the Bullet Cluster ... even though there are a host of gnomes and assumption based calculations implicit in that so-called observation.
The first (and only one so far) that you came up with is doubts about the distance to the Bullet Cluster as measured by redshift.

My last posting on this was:
BeAChooser: Back to the Bullet Cluster yet again.

The paper that I cited before (A direct empirical proof of the existence of dark matter) has the following paragraph
In this paper, we measure distances at the redshift of the cluster, z = 0.296, by assuming an Omegam = 0.3, λ =0.7, H0 = 70km/s/Mpc cosmology which results in 4.413kpc/′′ plate-scale. None of the results of this paper are dependent on this assumption; changing the assumed cosmology will result in a change of the distances and absolute masses measured, but the relative masses of the various structures in each measurement remain unchanged.
Note the emphisis that I added. This means that the distance to the cluster does not matter. So the question of whether the distance can be measured by redshift does not matter.

Next gnome?


I repeat my question: Next gnome?
Or do you admit that dark matter has been observed?
 
You mean these 4 numbers?



If you are wondering why I didn't even attempt to answer Frank, it's because of his very next statement after that demand, namely "If you can't limit your post to 4 numbers and associated discussion, then I will not read it."

He didn't want to deal with me as you have by actually addressing some of my concerns with sourced data. He just wanted to ignore all those concerns (some which you still haven't effectively addressed either but I have faith you will or at least could).

Furthermore, when he made this demand, he'd already demonstrated he wasn't even willing to read what I posted. I'd already addressed the demand (and that's the only way to characterize it) that I tell him what PC has to say about

-the age of the universe
-the abundance of light elements
-the existence of the CMB (e.g., temperature)
-the power spectrum of the CMB
-the spectral index of CMB fluctuations
-the flatness of spatial curvature
-the matter power spectrum
-the lyman-alpha forest
-the luminosity-distance relations of type 1a supernova

and then he'd simply ignored everything I wrote in response. And he went on ignoring whatever I wrote. So I figured ... why bother even making a response. And when the thread devolved into adhominens regarding my intelligence, religious views and political views, I decided to put the poor thing to sleep. And now you want to wake the dead? Shame on you. :D
.
I read this thread from beginning to end, but I seem to have missed your post(s) containing answers to those questions.

Would you mind repeating them (the answers, that is) please?

I also noted a number of other questions that did not seem to be answered (and that I am interested in getting answers to); I shall repeat them, or re-phrase them, in later posts.
 
Neither Zeuzzz nor BAC has ever come up with even one number predicted by PC, let alone four. That's because there is no such thing as PC. There is:

1) standard plasma astrophysics as studied by every astrophysicist,

2) some phenomena which have to do with plasma and aren't fully understood by anyone (solar flares, sunspots), and

3) a set of ridiculous ideas (like the electric sun, or the idea that rotation curves can be explained by EM forces) that are obviously wrong.

(Ben_m said something along these lines too a while back.) Predictions in category 1) are agreed on by everyone. You can't make good predictions in category 2), and if you could many in the mainstream would probably agree with you or at least be interested. Predictions of category 3) are dangerous, because they've gotten nailed quite a few times now on those.

To make the situation worse, BAC and Zeuzzz can't differentiate between these categories because they don't understand the physics. So saying anything definite is quite likely to get them in trouble; hence they resort to vagueness, evasion, and polemics.
 
I have been very polite to you quite often, to which you have often insulted me, called me stupid and made other character slurs, most of them for no reason and unprovoked.

David, can you show me where I called you "stupid" or insulted your intelligence. If you think I have, then post the instance and I will apologize immediately. But if I haven't perhaps you should apologize for claiming I did. I have questioned your reading ability on the basis of your repeatedly asking me questions that I had clearly already answered, for not understanding material that clearly says something different than what you concluded it said, and on the basis of you claiming I said things that I did not. Just as you are now doing yet again. But that certainly is not an attack on your intelligence. And as for character slurs, one of the reasons I left this thread is because you decided to attack my character by implying I might be a creationist (with absolutely no basis for doing so, by the way). And since then, you've also introduced politics into various science threads by repeatedly trying to link me to Karl Rove. As a result, you get ignored most of the time now.

You started name calling in my case long before I responded in kind.

That's not true. Let's look at the facts by doing a little search of JREF's data base. Turns out that this very thread has the earliest posts between us. You'll note that in post #57 - #59 on August 19th you started impuning my intelligence and background without knowing anything about me nor with any unpleasantness on my part (other than in post #41 calling you "naive" for saying "When the plasma cosmology makes a prediction that matches the data better than the current theory, then it will become the standard theory."). Here are some of your statements:

"I don't suppose you have heard of nutrinos have you?"

"I don't suppose you know about the neutrino?

"More crap. You have never been to an academic conference, have you?"

"have you read the history of physics much?"

"Ah, that is particle physics, you don't really know what you are talking about."

"Shows that you have never been to an astronomy or cosmology department, have you?"

Then the conversation between us continued with the normal bantering one expects (no real unpleasantness) until post #111 when you wrote "You talk like some sort of religouys fanatic, and one with an axe to grind." And then you added "Second be sure to ignore Cuddles, prove you are a troll." That's pretty hostile David. And I had not been hostile to you.

You continued in post #114 (30 August 2007) with this: "If you can't talk to Cuddles then you just shopw even more that you are a poseur and a fanatic." That's quite hostile David. Can you show us that I'd posted anything to you at that point in time even remotely as unfriendly on any thread?

Then in post #258 the discourse devolves further when you write " More clinging to what looks like a faith based appraoch and fanaticism on your part." and then call me a "Fanatic." just because I point out an article only talks about "gas" and never mentions "plasma". You close by saying "Your meglomania and lack of interrest in any debate is rather dull." That's false and hostile, David and unprovoked.

And in the very next post #259, you make your first attempt at linking me to creationism. Note that I've never mentioned it.

And you continued that tactic with statements like this in #339: "Thump your bible, you are a faith based dervish."

So pardon me, if I suggest that in your latest post you are trying the same tactics that got you ignored originally.

And please avoid the usual political slams slurs and character slurs.

I challenge you to post a political or character slur I directed at you. Would you like more of the ones you've tossed my way? Should I list the many comments you directed at me where Rove was mentioned?

Quote:
-the age of the universe

What age is suggested by your theories BAC, what does it predict.

I suggest you go back and read what I said about that earlier in this thread, David.

I believe you stated that there was a mechanism where such elements could be created, however I do not recall that you proposed a model for the proportions of the elements, nor their distribution.

Well then again you weren't paying attention nor to any of the other responses I've made on this and the other subjects you list.

I suggest that you save your drama king efforts for your employers and handlers

So who do you think my employers and *handlers* are, David, since you brought the topic up?
 
BAC, give in and give the four numbers.

They don't have to match with reality.

Say, Wrangler, have you read the book "Endless Universe: Beyond The Big Bang" by Paul Steinhardt and Neil Turok? A fascinating book and theory. It actually eliminates some of the things I don't like about Big Bang cosmology. And I like the way they ended the book. Thus.

And we can do all this secure in the knowledge that the debate will not be endless.

I'm really quite puzzled - what has that post, or anything to do with Arpian ideas, got to do with plasma cosmology?

I mean, there are no works by Alfvén or Peratt that contain any physical explanation of, or prediction of, 'intrinsic redshift', are there?

Nor has any fan of PC ever produced anything like this, have they?

Not to mention 'magic' - what could be more 'magic' than 'intrinsic redshift', a very definite statement about the concrete behaviour of atoms (and ions and electrons and molecules and ...) that is backed by not the slightest shred of evidence from any experiment ever conducted in any laboratory.

Would you mind saying a few words about this please?
 
Hi BeAChooser: You may have got the wrong posting- that is an calculation in the Arp objects, QSOs, Statistics thread.:D

Well, I took a look at that post.

First of all, as others have pointed out, it doesn't seem to have anything to do with PC. Of course I can't say that with much confidence because no one knows what PC is - it's a theoretical theory.

Secondly, the calculations are totally wrong. For example this:
BAC said:
Let's simplify the problem and just say that there are 30 possible values (or small ranges) of z ... from 0 to 3.0 ... in increments of 0.1. Now what are the number of permutations of 5 (r) ordered values from 30 (n) distinct values? It turns there are n!/(n-r)! possibilities. Which in this case is 17,100,720. That means the probability of picking those 5 specific z's in order from a range of 30 z's is 5.8 x 10-8.
is a textbook case of false a posteriori statistics.

The logic goes just like this: flip a coin 100 times, and record the results (HTTHTTTHH etc). Now ask, if the coin is random and fair, what are the odds of 100 coin flips producing that particular sequence? Well, no matter what the sequence was, the answer is exactly 1/2^100 = 1/10^30 or so, or 1 in a quadrillion quadrillions.

That's perfectly correct, but what do we conclude from it? If we are BAC, we conclude that such an incredible coincidence must be explained by some radical new theory, since our standard theory (that the coin is fair and has an equal and independent chance of coming up heads or tails) assigns such a ridiculously small probability to the outcome.

Obviously that conclusion is wrong, since no matter what the result of the flips was, we could always say the same. The logic is false, and is called a posteriori statistics.

You are acting innocent I credit you being at least as intelligent as I am, when you refuse to answer questions and engage in evasion and character slurs (like saying the problem is that I don’t understand a model or can’t comprehend it) , you are not answering questions. I can look but if I recall correctly I said that your behavior was like that of a creationist, if I said that you were a creationist then
I AM VERY SORRY.

When I say that you are acting like Karl Rove it is because you are engaging in all sorts of tactics other than critical thought and debate.

When you accuse me of a lack of reading comprehension you are flat out wrong. (I do have a learning disability but it does not effect my comprehension.)

You would have to tell me why you refuse to answer questions. that is your issue, but i don't think you should blame me for your inability or unwillingness to explain things.

i ask about the magnetic field in Perrat's model because it is a crucial question he or you are claiming that there are these tremendously huge magnetic fields and current but you do not show any evidence of their existence.

that is not a reading comprehension issue, that is your unwillingness to defend you own thoughts and models. Not my lack of comprehension.

So answer the question:

2. What size magnetic field and electric currents would be needed to produce the flat rotation curve that Perrat's model suggests. What evidence is there that they exist?

That's not true. Let's look at the facts by doing a little search of JREF's data base. Turns out that this very thread has the earliest posts between us. You'll note that in post #57 - #59 on August 19th you started impuning my intelligence and background without knowing anything about me nor with any unpleasantness on my part (other than in post #41 calling you "naive" for saying "When the plasma cosmology makes a prediction that matches the data better than the current theory, then it will become the standard theory."). Here are some of your statements:

"I don't suppose you have heard of nutrinos have you?"

Since neutrinos are in a very similar category, it is a very relevant question. I did not say you had not heard of them but that they were a similar particle to the dark matter hypoparticles. Same;same neutrino:dark matter
"I don't suppose you know about the neutrino?"

in response to your statement
And since when did science invoke invisible magic particles, forces and magic events to explain every deficiency in a theory?
and I also mentioned the pion although i did not mention quarks or changing neutrinos and other particles.

"More crap. You have never been to an academic conference, have you?"
Sorry, I didn't find that one, I do know that I said it. I can't recall the context and haven't found it yet.

So It was not a well phrased sentence, but I would suppose you were talking about the suppression of your pet theories.

I grew up with academics and around academics, all they do is talk shop, they never stop, they visit friends on vacation, they talk shop, they go on trips, they talk shop, they write letters, they talk shop.

They don't suppress you precious theories, they may not be interested in them.

ETA I just found it, you were calling "Big Bang Astronomers are acting like priests defending a religion" which isn't true, when you present the magnetic field scaled up from Perrat's toy model and show that there is a field or current of that strength then i would not think that about you.

My point still stands, there is no conspiracy to keep your pet theories out, all academics do is talk about their passion all the freaking time, my father has reviewed many an article, he does not care if he likes your idea, he wants to see the data and the rationale. (So please don't ask him for grant money if you are going to talk about cave bear altars and neanderthals burying people with marijuana.)
"have you read the history of physics much?"
here is the whole quote
http://www.internationalskeptics.com/forums/showpost.php?p=2883009&postcount=58

"that makes two. Oh, I see , you are just using hyperbole. have you read the history of physics much?

read up on Gell-Mann would you, some theoretical particles are eliminated, some turn out to be true, quarks are a theoretical explanation.
"

So I am countering more of your magic particle rant, in this case WIMPS, they could exist and there are studies being done regards them, the fact that they are hard to detect does not mean they don't exist.
"Ah, that is particle physics, you don't really know what you are talking about."
You may or may not but I am very certain your contention was that the search for dark matter was unprecedented in physics, and I was saying that you were wrong. Failed theories that couldn't make predictions stick abound.

Dark matter may end up that way, not yet.
"Shows that you have never been to an astronomy or cosmology department, have you?"
And each one of those was in response to a specific point that you made, I remember our conversation about the pi meson very clearly BAC, I can show you your rudeness in so many threads.

And the real issue is that you won't engage in discussion or defend your statements
Then the conversation between us continued with the normal bantering one expects (no real unpleasantness) until post #111 when you wrote "You talk like some sort of religouys fanatic, and one with an axe to grind." And then you added "Second be sure to ignore Cuddles, prove you are a troll." That's pretty hostile David. And I had not been hostile to you.
'like' is a simile and you were ignoring many pointed statements , not all of them rude.

I admit that was unwarranted sarcasm but considering I had started to ask you to show where the verification of Perrat’s model was on page two, I made a bad assumption. i am not sure if you are a troll.

You sure won't answer questions and find any reason to avoid it.

I was rude, I apologize.
You continued in post #114 (30 August 2007) with this: "If you can't talk to Cuddles then you just shopw even more that you are a poseur and a fanatic." That's quite hostile David. Can you show us that I'd posted anything to you at that point in time even remotely as unfriendly on any thread?
can you show where you were answering questions and not engaging in excessive hyperbole?

I am sorry BAC, my behavior was not at it's best.
Then in post #258 the discourse devolves further when you write " More clinging to what looks like a faith based appraoch and fanaticism on your part." and then call me a "Fanatic." just because I point out an article only talks about "gas" and never mentions "plasma". You close by saying "Your meglomania and lack of interrest in any debate is rather dull." That's false and hostile, David and unprovoked.
Then why won't you engage in debate? "looks like" is not saying "you are"

I was rude, I am sorry.

What size magnetic field would be needed to make Perrat's model of galaxy rotation work, has it been verified or demonstrated?

I asked that starting on page two.

I am sorry I was rude to you.
And in the very next post #259, you make your first attempt at linking me to creationism. Note that I've never mentioned it.

And you continued that tactic with statements like this in #339: "Thump your bible, you are a faith based dervish."
i was rude but when you refuse to present your case in the face of a direct question, that is faith based, you are basing it upon belief and not evidence.

I was rude, I am sorry.

Will you answer any of the four questions?

Mostly 2-4?

Or is there no evidence?
So pardon me, if I suggest that in your latest post you are trying the same tactics that got you ignored originally.
So pardon me, you say that you have a theory, but you do not want to explain it, you say that there is a model but you won't demonstrate it.

I can repeat the questions BAC, but why won't you tell me what evidence supports Perrat’s model scaled up to a galaxy? Why won't you explain hop a Lerner plasmoid avoids gravitational collapse? How do you want to explain the rotational velocity of star clusters?

I believe that plasma did play a huge role in the formative era of the universe in the BBE, it would make a lot of sense to me.

But i don't see where you have provided the evidence that Perrat's model is an accurate representation of a galaxy. What are the forces and fields where can they be seen?
I challenge you to post a political or character slur I directed at you. Would you like more of the ones you've tossed my way? Should I list the many comments you directed at me where Rove was mentioned?
Now you don't really want me to show all your hyperbole and evasions. If you offended by my comparison of you to Karl Rove then I shall cease.

cease fire

However i do not that you engage in a lot of diversion, distraction, character slurs and switching of topics. Those are what I have been characterizing and I will no longer do so.

I apologize.
I suggest you go back and read what I said about that earlier in this thread, David.
I did, and it does not explain what I have asked you.

Answer my four questions if you will, if you won't, whatever.
Well then again you weren't paying attention nor to any of the other responses I've made on this and the other subjects you list.
see there you are shifting attention, i did read the posts, i did not see the answers, i see suggestions and vagueness, not answers, and then some things that just beg the question.

Like the verification of Perrat's model. Nor did you really explain where the proportion of elements came from you suggested that they might be formed in jets and then suggested something about z-pinches making helium, but you seemed rather vague, you did not really point to anything that the PC/PU model can demonstrate for nucleosynthesis.
So who do you think my employers and *handlers* are, David, since you brought the topic up?

As to that they are the same as you talking about my reading comprehension, it is not related to the issue at hand nor is it critical thinking. So it is equivalent, it is me getting off topic and out of the realm of critical thought and into baiting and humor. I thought the stuff about gnome clusters was particularly funny.

But here is another long post where you just refuse to pony up, because you apparently can't or won't explain your own models.


So cease fire , please do not say I ignore your posts, please don't say I have a reading comprehension problem.

perhaps what is lacking is an explanation on your part.
 
Let's simplify the problem and just say that there are 30 possible values (or small ranges) of z ... from 0 to 3.0 ... in increments of 0.1.

That would be 31 possible values.
