Maybe this quasar isn't really that far away and bright; maybe it has an intrinsic red shift.

Then again, maybe this quasar is really that far away and bright; maybe the red shift logically indicates distance. Hmmmm?

Four "maybe's" in this thread so far...

Care to propose an intrinsic mechanism, Atko?
Didn't think so. The fact of the matter is, science is prefaced by one big maybe. Putting them in every sentence I've found only serves to make the crackpots think more highly of themselves. |

Mechanism and phenomenon are not the same thing. You can develop evidence for a phenomenon without knowing why it happens. To use a different example: Alfred Wegener proposed continental drift, had solid evidence that it had happened, but had no mechanism. So he was largely ignored. Fine … but he turned out to be right. This has not been explained in standard views. Really quite an oddball. http://xxx.lanl.gov/abs/astro-ph/0203466 And how does labeling people "crackpots" help promote honest, useful discussion anyway? Do you want to have a dialogue with these people or just continue to take shots at them? Frankly, I'm a bit fed up with the demeaning comments you slip into a great many of your posts. It doesn't do the good science you are presenting any service. |

N.B. The previous post appears to be a verbatim copy of this web page.
I have some issues with CSICOP, but most of your argument appears to be based on a single, unverifiable quote by one of its members. I find CSICOP irritatingly smug at times, quick to criticize "argument from authority" in general but just as quick to accept what organizations like NASA say as gospel. But your extended complaints about Kurtz defining what is considered science is unsupported at best.

dgruss --
The fact that there are crackpots in the world is really not up for debate in my mind. I don't claim that every "against the mainstream" idealist is a crackpot. I only claim that there is a fallacious argument out there that because science is built on induction that "anything goes". "I can believe in whatever I desire becuase science cannot do anybetter than provide 'maybes'." This completely disregards lessons from statistical science and paradigmatic development. If someone wants to challenge the mainstream, they have to realize what they're up against. Your example, dgruss, of dark matter is very apt in this case. The mechanism there was simply an added mass term that wasn't seen in the most generous mass-to-light ratios. A very straightforward and clear proposal. Vera Rubin was almost laughed off-stage, and well she should have been because the proposal was so contrary to what was paradigmatic. However, in the end, truthful investigations win out in science always. Rubin was vindicated and stands as an icon in astronomy. No one said that science was going to be a painless process of people who just say, "maybe, maybe, maybe". Science, if anything, is robust. In the back of the mind of all scientists is the assurance that some observation could be made that would cause a total reworking of the paradigm. However, the scientific endeavor would never progress if people simply gnawed on their fingernails all day worrying about such contingencies. That's why there is a peer-review process and an academic aspect to astronomy: it's to insure that we don't start from scratch for everything that we do. Of course, every person born on this Earth starts from scratch, and so there has to be people along the way who help them out. It's simply a shame that so many of them are so militantly ignorant of science. And when I say militantly ignorant, know that I mean that one can be ignorant of science and still be a fine guide into the world of scientific investigation. There are plenty of school teachers I have met over the years who didn't know much about science but understood the scientific method and had the yearning for learning in them that led them to be great teachers. I'm sure there are even people who are militantly ignorant in one area of science but could certainly teach well in another area. I am appalled by much of what comes out of the media passing as "science". Creationism, in my mind, is a horrendous joke. That the majority of Americans "doubt" the observational fact of evolution never ceases to amaze me and I can only assume it's because there is a consistent disinformation campaign going on by means of the militantly ignorant. Now, there are those who are militantly informed. Perhaps I fall into that category. Perhaps you think I take "potshots" at those who disagree with me. I don't think that's true. |

Atko--
As someone who addresses the physical interpretation of spectral shifts in my work on a daily basis, I wonder what the intent is when you post "Shhhh" and "That's a refreshing and accurate reflection on the real state of our knowledge". This seems to indicate to me that you possess some "accurate reflection" on the "real state" of our knowledge that hasn't been forthcoming on this board. How am I supposed to take such a statement? So I point out that the MOST CONSISTENT theory is the mainstream's and go on to describe why it's problematic to talk in wishy-washy 'maybes'. That's the sum total of my comments. I, frankly, am tired of defending a consistent measurement in astronomy as being dependent on velocity. There's a point where this "Arp-like" discussion over extreme objects is missing the forest for the trees. We have literally millions of redshifts that are taken and independent corroboration of a redshift distance relation by simple sclaing arguments if nothing else. Spectral shifts are proportional in the way we expect due to doppler velocities, and I have yet to see alternative proposal that is supported by this observational evidence. We've gone over other proposals in the past and found them lacking, and I just don't think that this argument that we "don't understand the redshift-distance relationship" has any teeth to it at all. There are errors on H<sub>0</sub>, true. There is at least one other mechanism that causes local redshifts independent of velocities, and there are distant-independent peculiar velocities. Other than that, what is left? That is the accurate reflection of the real state of knowledge that I can see. The rest is just grandstanding, idle speculation, or philosophical argumentation. |

This is an “Against the Mainstream” forum – not an “I worship the mainstream with every fiber of my being” forum. People should be allowed to post here without the responses to the science (good or bad) being combined with qualitative insinuations about the people that are posting the alternative views and the assigning of rude labels such as “crank” or “bizarre” or whatever. Quote:
I would hold up the exchange that Tim Thompson and I have recently had on the “Expanding Universe” thread as a model for how these discussions can be politely pursued. Quote:
There are people out there with a genuine interest in Halton Arp’s work. They should be able to discuss those ideas on this board without dismissive harassment and intellectual clubbings. Are you prepared to go on record as saying that not a single one of Arp’s redshift anomalies will turn out to be a real anomaly - period? Despite your protests, it IS still possible that Arp is right. That is why people continue to take an interest. For example, on the other thread, we disagree on the interpretation of the Virgo cluster peculiar velocity anomaly. You asked why I would think that is anything other than a statistical fluke. So we agree that it is unusual. Well, if I think there might be other examples, why shouldn’t I pursue that? Maybe it will turn out it’s the only example of that phenomenon and maybe it won’t. But what harm is done in pursuing the possibility? Don’t give me a lecture about the poor ignorant public that will be misled. That’s elitist. In the meantime you have not explained the NGC 7603 case http://xxx.lanl.gov/abs/astro-ph/0203466 Nor have you explained the NGC 1068 case: http://xxx.lanl.gov/abs/astro-ph/0111123 And note that both these examples are provided by researchers not connected to Arp. So its not just Arp saying these things. You often say to people on this board something to the effect of “Submit it to a Journal”. Well these people did that – and got it published. Arp has published hundreds of journal articles. Does this mean they are definitely right? – or course not. Does this mean they could be right? – Yes it does. That is why it is not ridiculous to discuss Arp on this board. Not to mention Morley Bell advocates that Arp’s phenomenon happen within the context of an expanding universe. There are lots of variations out there among these people. You demanded a mechanism earlier on this thread and on another threads a while back suggested Arp hasn’t even tried to explain his intrinsic redshifts. He has and this is the reference: http://adsabs.harvard.edu/cgi-bin/np...e5c03c80a11903 And here is their answer for the question about Time dilation in supernova light curves: http://adsabs.harvard.edu/cgi-bin/np...e5c03c80a11948 And if you can find something wrong with these papers that the referees missed, then take a look at the Quasi Steady State Cosmology – because that model is compatible with Arp’s examples too. No harm to science will be done in exploring the fringes and alternate possibilities – as long as the presentation of the possibility is honestly done. I have no problem with dishonest people being called on the carpet. But not every “against the mainstream” view is dishonest. JS, I'm sorry if this is harsh. That is not my intent, but I'm trying to defend the right of people to feel comfortable posting alternate views on this board. I think there is enough evidence in this thread alone to justify the discussion. |

You have taken an article which makes it very clear that the results are at best marginal, and stated your opinion like it's fact. |

Arp is, frankly, arguing from the perspective of one who has lost a debate. He's been around for ages and is an amazing observer. There's no question of that. But frankly, the theory he supports is no longer tenable, and he's holding on the last strands of a steady-state universe that has become little more than pie-in-the-sky. The WMAP results could have come out contradicting all of this. That would have been exciting and we might have taken an interest in Arp. As it is, there doesn't seem to be a decent motivation behind his curmudgeonry other than to continue to fight the wipper-snapper Big Bangers. This is a bit opionated, I know, but a lot of science comes through the dying out of the old breed. Arp represents one of the last of the old-breed in many ways. He's an iconic figure, but it doesn't look like he's right. Quote:
