# Alternative cosmology: the arp-narlikar's variable mass theory

Hi! I'm interested in alternative cosmologies and the variable mass hypothesis developed by arp and narlikar seems to explain better the discordant redshifts: but I can't understand how this theory calculates cosmic distances according redshift and time. Narlikar says that " We have here a flat spacetime cosmology in which light waves travel without spectral shift. How then do we explain redshift ? Consider a galaxy G at a given radial coordinate R, the observer being at R=0. A light ray leaving the galaxy at T0-R/C reaches the observer at time T0. Since the masses of all subatomic particles scale as T^2, the emitted wavelenghts go as m^-1 & t^-2.Hence we get the factor:

1+Z=

T0^2
__________
(T0-R/C)^2

I don't understand...if a galaxy has a redshift z=6.5 for exemple, how distant from us is it ?
There is somebody well up in these things ?? Thank you...

Arp's theory hasn't changed in decades despite the wealth of new observations in that time. You haven't detailed what you mean by 'discordant redshifts' so I have to assume you mean the fact that there are some Quasars and galaxies near each other in the sky that have different redshifts? This might have been a problem when there were only a handful of known Quasars, which is when Arp came up with this idea, however there are many more known today (thousands? tens of thousands? I'm not sure of the exact number) and there is no longer any hint of the 'discrepancies' you refer to, that is to say the number of galaxy-Quasar nearby pairs seen is consistent with what would be expected from random chance line of site alignment and not the fact that these 'pairs' are actually nearby to each other in space. In addition the expanding universe model has made a number of predictions that have been verified observationally, such as the properties of the CMB, the presence of the baryon acoustic peak in galaxy redshift surveys, the light curve width and redshift relationship seen in Supernovae Type 1A spectra etc etc. Many of these can't be understood in the Arp model, effectively ruling it out.

Discordant redshifts have been discovered also recently: for exemple in the Stephan's Quintet: one of the galaxy group, NGC 7319, has a redshift of 0.0225. A tiny white spot is a quasar discovered in 2003 either silhouetted in front of the opaque gas clouds or embedded in the topmost layers of the dust. The redshift of the quasar is 2.114. Pasquale Galianni, Margaret Burbidge, Halton Arp, V. Junkkarinen, Geoffrey Burbidge, and Stefano Zibetti, the astronomers who wrote the paper describing this discovery, also studied the dust clouds surrounding the quasar: Radio, x-ray and spectra observations show that this area is disturbed. These gasses are more turbulent than the gasses in other regions of the galaxy. That seems to indicate that something big and powerful has passed through, moving outward from the nucleus. In addition to the jet, the region of the galaxy near the quasar is glowing with an excess of low-density emission lines from ionized gasses. But nothing is "there" to light them up except the impossible quasar. This is not the first definitive disproof of the redshift = distance principle, although it may be the best to date. Halton Arp has been accumulating discordant redshift evidence since the late 1960's.

And however my doubt is to understand cosmic distances according to this theory: who can help me ?

The more Quasars we find the more we find that happen to appear near galaxies. The point is not to focus on the handful of chance alignments but rather the vast majority that do not have these alignments, and also to note the expected number of alignments given the observed angular density of galaxies and Qausars.

This is an extreme claim that is poorly supported by this paper - and virtually ignored by the scientific community at large.

Maybe it's ignored by the most of scientific community because puts in crisis big bang assumptions and with it years and years of honoured careers, degrees,...
I would make clear here that I'm not for or against the big bang theory: I only say that some things don't fit in with: what about galaxies with Z high redshift (Z>5 or 6 !) already formed with masses of billions of suns ? And quasars with high metallicity levels ?? And it can go on so...

This is pure fantasy, scientists love overturning long held views, even if they held them themselves for a long career. It is precisely what scientists are striving for. But it has to be supported by the evidence and if the evidence overwhelming supports the current model then it is very hard to do. Of course it is very easy for people to claim they have a better theory by willfully ignoring the evidence.

As you point out, there are some things we don't understand about the current model, high metalicities at high redshift being one example. All this says is that we don't understand everything, which we knew anyway.

Dan74, I completely agree with you last reply to me. Alternative theories have never got much exposure unless its proponents are well-known and respected.

You're completely right. High metalicities is a big problem for the BB theory at those distances, according to many BB detractors. I have not heard any BB theorists as yet respond to this observation, other than maybe questioning the interpretations of the observation.

If alternative theories are proposed that do a better job than the 'main' theory then they become the prevailing theory and cease being 'alternative'. It doesn't matter who proposes them, if a theory fits it will fly in the end. That's not to say that the modern practice of science is devoid of any sociology, obviously the titles and achievements of someone are not ignored when considering what they have said, but none the less if a complete unknown comes up with something interesting scientists do listen.

As a case in point, Halton Arp is still well respected for being a very good observer who has achieved a lot of great science. None the less his cosmological model is clearly unsupported by the evidence and hence is not respected. The cosmological community didn't simply believe Arp because of his reputation, his idea was judged on it's merits, or lack there of.

Here is where you make your fatal mistake. There is no such thing as a 'Big Bang theorist' that might be in opposition to a 'non BB theorist'. You are characterising scientific debate as if it was politics. Of course cosmologists don't come out and 'defend' the BB from possible anomalous observations. The very notion that you would expect that to occur belies a misunderstanding of the whole process.

Scientists don't sign up to an idea and then spend their career trying to prove that idea over any other. Rather all observations, experiments etc are considered continuously in order to arrive at the best possible model considering all the evidence. The vast majority of the evidence points to a particular model. Despite this, not all predictions that model makes correspond to what we observe. This just says the theory isn't perfect. Maybe we should expect to see the metallicites that we see at high redshift since modeling the processes that increase metallicity is a very uncertain field. Maybe the predictions are correct, and the observations are pointing to problems somewhere else in the model. The point is we don't know everything and both theorists and observers are madly trying to work it all out. Possibly the resolution won't change the basic elements of the model, perhaps it will, but no one is out to 'defend' the model, but instead find a better one that does fit all the data. The improved model might be just like the old one with minor adjustments, maybe it will be fundamentally different but the point is that the evidence is always the driver.

There is no one in the world who would characterize themselves as a 'Big Bang Theorist'.

I don't know where the above quote came from but theorists such as Guth, Gamow, Leamartre, etc. etc. all were part of formulating the BB theory. Granted Hoyle supposedly named the theory. It would be simply semantics to say that they didn't call themselves
BB theorists. If they didn't say it, it seems likely that's how they were characterized by most.

Wallace, when a theory is in trouble, I believe, it is forcefully defended. A case in point was
-- Verschuur when he asserted that intragalactic hydrogen radiates at the same frequency as the supposed CMB. By his published paper in the prestigious Astrophysical Journal, Nov. o7, he asserted that our satellites would not be able to tell the difference between the two therefore the map of the CMB would accordingly not be accurate. This implied for some that there might not be CMB, therefore no BB. Related publications asked the question, Big Bang or Big Goof? The response to this assertion, it seemed, was like a duck on a June bug. To call their response an attack, would not seem to be an overstatement.

If you've spent your whole life working on and with a theory, it would seem natural that some would aggressively defend their life-long work. The other logic of your comment seems reasonable to me.

Just a side bar: It would be more accurate to characterize metallicity in high-Z entities as an evolutionary mystery. BBT merely constrains the time line. Stellar and galactic evolution are still poorly understood, hence, this a very weak argument against BBT.

Guth etc are theorists that came up with ideas that are part of the Big Bang model. But they are not 'Big Bang Theorists' in the way you used the term, i.e. those whose goal is to defend the Big Bang theory. If new evidence showed that the theory was untenable they wouldn't try and defend it but would try and make a new theory they fit the evidence. Hence they are theorist, not 'Big Bang theorists'.

There are many many many reasons why intergalactic hydrogen would not give the same signal as the observed CMB. Verschuur's work was not attacked because it was 'anti BB', rather any 'attacks' focused exactly where they should, on the methodology, assumptions and predictions of his work. He made some errors, jumped to too strong conclusions and ignored much of the information present in the CMB that is not explained in his theory. The idea, like any, lives and dies on the evidence, and this one certainly died.

If you've spent your whole life working on and with a theory, it would seem natural that some would aggressively defend their life-long work. The other logic of your comment seems reasonable to me.

But people don't spend their whole life working on a theory, the theory changes from day to day. That is to day the 'Big Bang theory' that exists today is different from the one we had last month, which differed from the one before that. The theory is constantly updating and changing.

Those observers that asserted metallicity did so by studying the absorption lines of galaxies and determining the elements which when renormalized for the red-shift, seemingly showed elements in the periodic table of iron and heavier. At these great distances critics have asserted that this analysis was misconstrued. Seemingly there would be a good reason to doubt this observation because it would seem to challenge BB cosmology. In the near future either evidence will built up to be beyond dispute, as far as these observation, or numerous additional observations will show that their interpretation was wrong.

We will soon find out.

The observations may not challenge BB theory, since we don't understand fully how to model the evolution of metallicity. It may well be that when we can model this better we might expect to find the observed metalicity at this high redshift. So it doesn't come down to either the observations or the BB being wrong, it is perfectly plausible that they are both correct.

Modeling metallicity evolution requires understanding well the formation of the first stars, the formation of galaxies and the formation of AGN. We really only have sketchy ideas about these processes so doing cosmology via metallicity measurements is difficult, since we can't know for sure what we would even expect to see!

Wallace, agreed,

"The observations may not challenge BB theory, since we don't understand fully how to model the evolution of metallicity." But current theory would need to be changed. At the rate that we now see matallicity evolve, according to related theory, it would take 5 to maybe 8 billion years to produce the metallicity that we presently observe within the Milky Way, which is similar to what these observers claimed to see in those distant galaxies.

Maybe if only very large stars formed in the very beginning. A great deal of Supernovae activity occurred within a billion years or so this might produce this kind of metallicity claimed. This however has been the history and problem with the BB theory. Almost ever year new observations require changes in the theory. Most theorists right now know little about viable alternative theory so it would seem likely that all they would do is keep changing BB theory.

If you think the BB is correct and don't want to see it replaced then you might hope that there will be no more similar observations, or worse, similar observations at greater distances, that the ones that were already observed are shown to be incorrect interpretations, and that they don't keep finding more and more galaxies at continually greater distances.

In general, at about 12-13 billion years you would expect to see the "dark ages" according to BB cosmology. If not the estimated age of the universe, according to the BB model, would need to continue going up. They also could change the way they calculate the distance of galaxies, or could propose that the red-shifts are magnified in some way by a Dark Energy effect or other alterations of theory.

Don't worry PanTheory; Big Bang "theorists" will find the way to adjust this and all others parameters not in line with theory: age universe don't fit in ? No problem, they lower Hubble's constant value or insert things like 'cosmological constant', ecc..well, in october Hubble telescope should have a new powerful 'eye', the wfc3 that, if I don't mistake, will discover galaxies until a z=10 or so redshift: what it'll happen when and if they'll discover galaxies already well formed at this redshift?

All right Wallace but we can talk about alternative theories, as I'm doing, waiting for big bang theory be proved at 100%..and I can give other points of reflection about 'trouble' elements for big bang cosmology:

-CMBR anisotropy

-Biases in high-z SN Ia observations

-Discrepancies in Dark Matter Observations

-Old massive galaxies at large redshifts (already hinted)

-Fractality of large-scale structure

-Origin of structures as the 'voids' in the universe

-Galaxies, quasars and disparate red shifts (already hinted)

-Discordant results for light element abundances

-Angular size/redshift relation

No theory in science is ever proved at 100%, so you will be waiting a long time. All we can ever do is go with the most likely theory at a given point in time and no cosmology theory comes within cooee of the Big Bang at present.

..and I can give other points of reflection about 'trouble' elements for big bang cosmology:

-CMBR anisotropy

Um, the CMB anisotropies were predicted by the BB theory before they were observed and the observation won a Noble prize precisely because it was such a monumental piece of evidence for the theory!

-Biases in high-z SN Ia observations

High z SN1A observations indicate acceleration, which is also indicated by the amount of structure growth observed between recombination and today. These two measures of expansion agree very closely, an enormous co-incidence if the underlying theory is not correct.

-Discrepancies in Dark Matter Observations

What are you referring to? The only real 'observations' we have of dark matter are through gravitational lensing, and these results have given a stunning agreement with the dark matter predicted via dynamic measurements (i.e. galaxy rotation rates). Also the Bullet Cluster results are a real smoking gun for dark matter.

-Old massive galaxies at large redshifts (already hinted)

Galaxies at high redshift are found to be much smaller, younger and very different morphology to low redshift galaxies.

-Fractality of large-scale structure

The measurements of this are in agreement with the predictions from BB theory !?

-Origin of structures as the 'voids' in the universe

Again, voids are predicted from N-body simulations of the standard BB theory!

-Galaxies, quasars and disparate red shifts (already hinted)

The number of chance galaxy/QSO alignments is in line with the expectation from random chance. Most QSO's are not near galaxies (except their host galaxy, which is usually not visible though sometimes is for low z quasars).

-Discordant results for light element abundances
[/quorte]

Light element abundances are incredibly concordant. There is a problem with Lithium abundance, but if you throw the BB away it is much harder to explain why everything else was so perfect, than it is to explain why the Lithium is slightly different from what would be expected.

-Angular size/redshift relation

Relativity predicts an angular size/redshift relation that has been confirmed by observations

I agree it won't be long now. But theorist that don't have a reasonable known alternative will make the proper adjustments as you suggested. They would have to first deny that these are old galaxies. Next they could come up with some wild hypothesis like: Einstein predicted four dimensional space. As you would move in a straight line eventually you will end up where you started. That is one of their explanations why there is no center of the universe.

OK, here's the kind of theory they might come up with if they have to. In normal observations tidal forces of gravity are thought to have little effect on galactic light. But at these great distances intervening galaxies will distend the light from distant galaxies, falsely indicating a greater distance than what really exists. They could try out this hypothesis for a while until the theoretical community seriously starts looking around for better alternatives.

That's when it will really begin to be interesting as you suggested.

Arpian cosmology is an urban legend that persists despite spectacular failures in the face of modern observational evidence. Asserting it is a conspiracy against Arp . . . priceless.

I agree the observance of large, high metalicity galaxies at high z is a modeling problem - mainly one for particle physicists to resolve. The preponderance of evidence still favors BBT. It is impossible to rule out formation of large, rapidly evolving galaxies composed primarily of pop III in the very early universe.

That's not true in my case. Over 23 years ago I have explained the accelerating expansion of the universe as an illusion (with Einstein's theory of gravitation). The theoretically predicted Hubble constant and its acceleration (discovered only 15 years later) are observed as Einstein's theory predicts them for a static universe (within a reasonable error of course: H_0 as 70km/s/Mpc for density of the universe 6x10^{-27}kg/m^3 and dH/dt/H_0^2 as -0.5), and yet no scientist, even in my university where I was an astronomy student, never payed any attention to it. I still can't make any of experts to read my paper ("no time" they say). The referees didn't find an error but it was irrelevant for them since all believed that "the universe is expanding". And if proving theoretically with Einstein's gravitation that in the stationary universe of density of ours there must be an illusion of accelerating expansion with observed parameters, not to mention local quasars, and 'anomalous' acceleration of space probes (also discovered later), is not interesting enough then please give me an example of what is more interesting than that. BTW, what is "high metalicity of quasars" and why it seems to be strange?
As a case in point, Halton Arp is still well respected for being a very good observer who has achieved a lot of great science. None the less his cosmological model is clearly unsupported by the evidence and hence is not respected. The cosmological community didn't simply believe Arp because of his reputation, his idea was judged on it's merits, or lack there of.
Arp's cosmological model is wrong but only because thanks to BB experts he thought that those experts excluded Einstein's gravitation as a possible source of cosmological redshift and that's why he accepted Narlikar's theory of flat spacetime (which is the result, following from Einstein's theory as well) and variable mass (which is not supported by Einstein's theory). If he had known that Einstein's theory explains his observations of local quasars, he wouldn't need variable mass theory. So thanks to BB experts we are at least 23 years behind where we could be if those experts had time to read a short one pege explanation by "a complete unknown" how Einstein's theory explains the "cosmological redshift" (which they themselves for a very simple reason couldn't find in Einstein's theory; I hope it is not treated as highjacking the thread, since it is a direct response to your message).

Another question: is there any way of making astronomers aware of the fact that Einstein's theory of gravitation plus the principle of conservation of energy (presently denied by BB experts) are able to produce for the stationary universe a unique value of the Hubble constant coupled only to the average density of the universe and its acceleration coupled only to its value at the observer?

Can Einstein's theory of gravitation be discussed, even if it happens to predict the redshift in stationary universe (corresponding to the dynamical friction of photons in the Newtonian approximation)? The problem with it is that the dynamical friction of photons in Einstein's theory comes out as inversly proportional to the radius of curvature of space and in the Newtonian approximation there is negligible curvature of space so this "friction" comes out as negligible and as such may be used to hypothesize that it can't be responsible for the cosmological redshift. Not so in Einstein's theory and for the radius of curvature R=4.3 Gpc the Hubble constant comes out as 70km/s/Mpc (theoretically as c/R, where c is speed of light). Which is dengerously close to what is observed and fairly tough to explain within BB theory in which the dynamical friction of photons is assumed to be the same as in Newtonian approximation ("negligible").

JJ, an static Universe within GR requires an exact balance between matter density and the cosmological constant. If this was the case, I guess you would get a small gravitational blueshift from distant objects, but certainly not a redshift. Not in Einsteins gravity. I have no idea what you mean by 'dynamical friction of photons' but it sounds like tired light, a theory that has been amply demonstrated to not fit the data.

My point that you claim hasn't been applied to your idea clearly has. You mention a very small subset of the data. What does your idea predict for: the CMB, the observed evolution of structure with redshift (including a prediction of the function form of this), the Lyman alpha forest, the matter power spectrum, the Baryon Accoustic scale in the matter power spectrum, the star formation rate evolution of galaxies, the 'Quasar epoch' around redshift 1... the list could go on for a long time.

The current theory predicts well all of these and more. A better theory has to do better over all available data, not just a very small subset, and your theory fails even for the very basic data you mention.

Wallace, you are right about it sounding like tired light and about the tired light being discredited, but you are wrong about calling it my theory since it is only pure Einsteinian relativity or rather it exact consequesnce that my part of it is that I noticed it in Einstein's theory of 1916, or rather 1917 when he discovred the "static universe").

It is a much deeper issue than I'm allowed to write about here without being thrown out from the forum for highjaking the thread. So if you are interested in details you would need to open a separate thread in which anti-BB Einsteinian physics and all the other things that you mentioned could be discussed, without interference from moderators and I can bet my whole bonus I just got from Bush against just one dollar from you that you won't be able to find a hole in what I claim is pure and exact consequence of Einsteinian physics (not necessarily known to Einstein himself since, as he mentioned, after "mathematicians started explaining his theory to him he stopped understanding it").
