Author | Topic: Creation cosmology and the Big Bang | |||||||||||||||||||||||||||||||||||||||||||
NoNukes Inactive Member |
You've picked a difficult topic to debunk, at least to the satisfaction of a difficult audience.
There are a number of papers written on the subject of red shift quantization/periodicity. The most famous ones are by Napier, Tifff, Arp. Of course there are papers debunking these claims. The debunking papers are far fewer and there simply does not seem to be much interest in debunking the already debunked. Mainstream astronomers are seem about as interested in quantization as they are in astrology. I'd be suspicious of a recent supportive paper that does not address the analysis in contemporary papers debunking the old analyses or that simply repeat the old analyses using those same methods or the same small data sets. An example debunking paper: Tang, S. M.; Zhang, "Critical examination of QSO Redshift periodicities and associations with galaxies in Sloan Digital Sky Survey, Data" ShieldSquare Captcha ABE: As Jar has pointed out the article is dated 2005. Edited by NoNukes, : No reason given.Under a government which imprisons any unjustly, the true place for a just man is also in prison.

From Critical Examinations of QSO Redshift Periodicities and Associations with Galaxies in Sloan Digital Sky Survey Data (2205): 2205? or maybe 2005?Anyone so limited that they can only spell a word one way is severely handicapped!

general papers finding no preferred redshifts do not consider Earth’s motion in the Milky Way (this problem tends to smear the data). Show me.
In addition, preferred redshifts are sensitive to accuracy in the distant galactic redshift measurements so large numbers of very distant galaxies (that tend to be less accurate) cause accumulated measurement errors also smearing the data. This is hilarious. More data causes the results to be lost. A perfect response to claims that the original studies used too little data because that was all that was available.Under a government which imprisons any unjustly, the true place for a just man is also in prison.

NoNukes my friend...
An example debunking paper: Tang, S. M.; Zhang, "Critical examination of QSO Redshift periodicities and associations with galaxies in Sloan Digital Sky Survey, Data" ShieldSquare Captcha quote: Actually, this is one of the papers that I could not locate any point at which the authors subtracted the relative motion of the earth in our galaxy. I have looked over the calculations and the data sets, I even tried to search any reference to earths relative motion. As far as I can tell the calculations neglect the earths Doppler shifting effect.

That's not remotely true. The Higgs mechanism has no role to play in the formation of mass in the Big Bang theory. It explains how the Electroweak Force became the Electromagnetic and Weak Nuclear Forces. It certainly does not play a primary role in the Big Bang theory as the Higgs was first proposed decades after the Big Bang model. The Higgs field is essential to the Big Bang and if it missing, (it is a myth) then the Standard Model for particle physics will certainly be downgraded or it will collapse altogether. You have no idea of the repercussions of the missing Higgs.

Boy oh boy, you just love out-of-date information!! Google it up and post it without thinking, that's you. Yes, there used to be some controversy about whether or not redshifts were quantized. That controversy is settled; redshifts are not quantized. A few researchers (mostly creationists) still hold on to the idea but the evidence against it is overwhelming. Complete nonsense my friend This next article you cited has nothing to do with the periodic redshifts I am talking about but the hypothesis that quasars are ejected from centers of distant galaxies.
We have used the publicly available data from the Sloan Digital Sky Survey and 2dF QSO Redshift Survey to test the hypothesis that QSOs are ejected from active galaxies with periodic non-cosmological redshifts. The next article you cited has a lot of doubt about the reality of Q-Redshifts but still finds them in the data to the order of 2 sigma (about 77.7% certainty of Q-redshifting). I think this article ends up in my camp.
The previous result, based on selected samples showed the existence of the periodicity in the galaxy redshift distribution at a very high significance level. We found that at the 2σ significance level some effect was observed. Your next argument is a very common fallacy of ARGUMENTUM AD NOVITAM. That kind of argument can only be made if significant evidence to the contrary is obtained. No such evidence has become known to reject the original discovery. You make the following statement:
Anything published before 2000 (the first data release from the Sloan Digital Sky Survey) is definitely out of date. (Wikipedia notes in its list of major papers claiming redshift quantisation that "All of these studies were performed before the tremendous advances in redshift cataloging that would be made at the end of the 1990s. Since that time, the number of galaxies for which astronomers have measured redshifts has increased by several orders of magnitude." Please remove all links to papers published before 2000. It would be best to question papers published before 2007 (the fifth data release of the SDSS) What do you have left?

Actually, this is one of the papers that I could not locate any point at which the authors subtracted the relative motion of the earth in our galaxy. I have looked over the calculations and the data sets, I even tried to search any reference to earths relative motion. As far as I can tell the calculations neglect the earths Doppler shifting effect. Nonsense. We can positively rule out your relative motion proposal as a cause for the Tang, Zhang study finding a null result. On page 7-8 of the paper, the authors reproduce the periodicities found using the smaller data set and then show that the periodicities are absent in the larger set.
quote: Given the ability of the authors to reproduce the original results, the explanation cannot lie in the kind of methodology mistake that you describe. Selection bias seems to the best explanation for the apparent periodicities in the smaller study. Edited by NoNukes, : No reason given.

Maybe it will help if I point out your obvious mistake...
zaius137 writes: The Higgs field is essential to the Big Bang...quote:If the Higgs boson was essential to the big bang, then it wouldn't be only applicable to particles after the big bang. Are you unable to see that your own quote doesn't support the Higgs boson being connected to the big bang?Can you not see that it actually says the opposite? CRYSTALS!!

This next article you cited has nothing to do with the periodic redshifts I am talking about but the hypothesis that quasars are ejected from centers of distant galaxies. Ah, I see that you don't understand what quantized redshift is. Please read the Wikipedia article, especially the parts about QSOs, and then retract your claim.
The next article you cited has a lot of doubt about the reality of Q-Redshifts but still finds them in the data to the order of 2 sigma (about 77.7% certainty of Q-redshifting). I think this article ends up in my camp. Perhaps so, but it provides little support.
Your next argument is a very common fallacy of ARGUMENTUM AD NOVITAM. That kind of argument can only be made if significant evidence to the contrary is obtained. No such evidence has become known to reject the original discovery. Gibberish. My next argument was:
quote: Now, earlier I did write:
quote: But that's not an argumentum ad novitatem (not novitam, if you're going to do Latin get it right). The SDSS results are not better simply because they are newer; they are better because they contain orders of magnitude more data and significantly higher accuracy for objects over a very wide range of redshifts. You are rejecting incredible increases in dataset size and accuracy because it's new, something of a reverse argumentum ad novitatem. Remember:
quote: You cite: Rutgers University Department of Physics and Astronomy Does not use the SDSS data, therefore irrelevant. You should, however, read it; it discusses the QSOs that you claim are irrelevant in great detail. http://arxiv.org/abs/astro-ph/0606294 Does not use the SDSS data, therefore irrelevant. http://arxiv.org/abs/0711.4885 At last, someone actually uses the SDSS data! But wrongly. See John Hartnett's Cosmos. 1. Introduction:

quote: Ain't no quantized redshift.

Actually I do. Currently we know that something generates an electroweak charge in empty space that essentially splits the electroweak force in two (into the weak force and the electromagnetic force). The Higgs is nothing more than the simplest mechanism for doing this. So, if it isn't found, we begin looking at the other mechanisms. Nothing will happen to the Big Bang model.

The Higgs is nothing more than the simplest mechanism for doing this. What if there is no such thing as an electroweak force?, only electromagnetic forces and weak nuclear forces? What would happen to the big bang theory then? For that matter, what would happen to the big bang theory if dark matter and dark energy were myths as well?

Knowing that, are you now able to figure out what affect it would have on the Big Bang? That all depends on whether the Big Bang was responsible for producing the electroweak force.
Dark Matter and Dark Energy have both been observed. Observed or just wrongly concluded by misinterpreting the evidence?
Your question is similar to asking "What would happen to cowboys if horses were myths?". No it isn't.
Sure, we can waste some time discussing an imaginary scenario - Why do you say it is imaginary? It is no more imaginary than the big bang itself.
but it is not an actual argument. I didn't know that I was trying to make an argument. I was asking questions about the validity of certain claims that everybody seems to accept as true.

How do you know that?To quote Wiki: "The physics of the electroweak epoch is less speculative and much better understood than the physics of previous periods of the early universe. The existence of W and Z bosons has been demonstrated, and other predictions of electroweak theory have been experimentally verified." foreveryoung writes: No it doesn't.
That all depends on whether the Big Bang was responsible for producing the electroweak force. foreveryoung writes: Observed.
Observed or just wrongly concluded by misinterpreting the evidence? foreveryoung writes: Yes it is.
No it isn't. foreveryoung writes: When you make something up in your head, it is called imaginary.
Why do you say it is imaginary? foreveryoung writes: Correct. It is no more imaginary than the big bang itself.Horses are no more imaginary than the Big Bang. foreveryoung writes: Good. We are agreed that you have produced no arguments against the Big Bang. I didn't know that I was trying to make an argument. Edited by Panda, : No reason given.CRYSTALS!!
