How could "temperature change of the universe throughout its evolution from the zero origin" explain the existence and the blackbody spectrum of the CMBR? As the universe evolves, its temperature rises. Looking back into the past universe from the present (anytime), its combined temperatures, right from the origin, are on display as background radiation. But the evolution of the universe doesn't cause it to have a temperature in the sense you want it to, since the universe is not in thermal equilibrium. More specifically, the energy being released in various processes (stars, accretion) is nowhere near thermalized. You can't get blackbody radiation from a nonthermal source. Also, the evidence is that the temperature of the background radiation has *declined* with time. Paul |

We'll see. and why it has a blackbody spectrum? It's based on temperature change of the universe throughout its evolution from the zero origin. It has the spectrum of the CMBR, just like your theory does. How could "temperature change of the universe throughout its evolution from the zero origin" explain the existence and the blackbody spectrum of the CMBR? You haven't explained that below. As the universe evolves, its temperature rises. How could it? Where should the energy come from? Looking back into the past universe from the present (anytime), its combined temperatures, right from the origin, are on display as background radiation. What is "the temperature of the universe"? What exactly is the source there? There are no discrete stages of evolution of course. The changing curve from the entire past, and the uniform temperature curve generated in the present must all add up to equal 2.73K. So you say that different blackbody curves added up give again a blackbody curve? But the average temperature of the current universe alone must be higher than when the rest of the background is added to it. A point which I have never properly explained, anywhere, is how I arrived at the equally spaced stages in the evolution of the universe for my graph plots. Firstly, the universe is not expanding. The noted redshift is due to a reduced speed of light in a lesser evolved universe. Does this explain why redshift is *proportional* to distance? Assuming that the current temperature of the universe is 3.4K, Why should one assume that? the temperature at the halfway mark toward the origin is 1.7K, where the speed of light will be halved, relative to now. Why should the speed of light be proportional to the temperature of the universe? For a four input stage graph plot that aligns with the CMBR, the blackbody curves are, .85, 1.7, 2.55 and 3.4 K. But I don't know what the true uniform temperature of the current universe is, and that determines what other temperature graphs should be included from the past. The curve is always much the same though. Shouldn't one *integrate* over blackbody curves of different temperature? [snip] Its temperature is increasing at a logarithmic rate, hence the ^1.12 adjustment How do you get from a logarithmic temperature increase to a factor ^1.12? And I've read it so many times! Huh? How is that supposed to answer my question? to each (equally spaced relative to a fixed time zone) curve generated from the Planck equation, #=((8*pi*h*f^3)/(c^2*(EXP((h*f)/(k*t))-1))) ^1.12 In order to apply the Planck equation, you need something material which is in thermal equilibrium. What is this in your model? In the standard BB scenario, it was the plasma which filled the early universe. Thermal equilibrium is achieved over time. Redshift that extends to light speed noted in the current universe has always been as it is, right from the origin. At any stage of evolution, that picture was the same. It's not possible for one clean spectral line to emerge from that completely blended spectrum. You did not answer my question: *what* is at thermal equilibrium in your model? What exactly is the *source* of the CMBR? I notice that you snipped this link: http://www.astro.ucla.edu/~wright/stdystat.htm#Tvsz and entirely ignored my demand that you address this evidence. [snip] Dark matter can certainly be explained, if it's required. That has nothing to do with my argument above. Try again, please. That argument has nothing to do with a zero origin universe either. It is an argument about observational evidence for the BBT. So if you claim that you can explain all the evidence which the BBT can explain, you need to address this. Why don't you bother? Why should I explain observational evidence for predictions of the BBT when it has nothing whatever to do with the zero origin universe? I did not say that you should explain observational evidence "for predictions of the BBT". I said essentially that you should explain observational evidence which is simply there, and which the BBT *can* explain. Don't you understand the difference? My original argument was: if the CMBR is assumed to have a cosmological origin, the parameters we derive from it (Hubble parameter, density of dark energy etc.) are nicely consistent with determinations using other methods. You *still* have not explained how that could be possible if the CMBR has *not* the origin the BBT proposes. Anyway, most of the evidence that supports the BBT is from distant sources. In this unbounded universe, if one searches for long enough, seeking evidence of some effect which is predicted by a theory, that evidence will probably be found. But the argument above was not about "evidence of some effect which is predicted by [the] theory". Don't you understand the argument, or are you delibarately avoiding it? But the real cause for what is observed may be entirely unrelated. "may". Indeed. You are free to present an alternative explanation. So far, you haven't. Compiling much of this type of evidence forms a solid foundation which is unjustifiably hard to wedge apart. There is nothing "unjustifiable" about that. Since the argument is to do with your rejection of the zero origin universe, cluttering the post with BBT predictions is pointless, Again: the above was *not* about BBT predictions. Read the argument again. Try to understand it this time. And then address it, instead of trying to weasel out of it again. so I've snipped what I consider irrelevant. In other words: you simply snip all evidence for the BBT which you can't explain, and then claim that your model can explain all the existent evidence. How convenient. You can put it all back again if you want. ----- ----- The all sky picture of the universe from the zero origin is crystal clear. According to that picture, matter is slowly clumping together, That's the same as the BBT says. increasing the depth of dimension, of space. That's incomprehensible. Exactly. That's what I've been trying to tell you all along. Well, since it was you who coined the phrase "increasing the depth of dimension, of space", and not actual cosmologists, then why do you agree with me that this phrase is incomprehensible? If even you yourself think it is incomprehensible, why did you coin it? The picture provides a remarkable insight into how the matter content of the universe is evolving. The picture at the very origin would have contained one infinitesimally minute anisotropy That's very close to what the BBT says. within a completely black background. That is contrary to the observations. I notice you choose to ignore that. A universe with zero anisotropy would not exist. Why not? Because there is nothing there. "zero anisotropy" does not imply "nothing is there". When you better understand the zero origin universe you'll know why. As long as you continue to simply ignore the evidence for the BBT, I see no reason to try understanding your model. For example, you apparently now also ignore the Sunyaev-Zel'dovich effect and the integrated Sachs-Wolfe effect. If a photon is moving through a deepening potential well, it will exit the well with an extended wavelength (I think). But that is clearly impossible. Well, then why has this been observed? The fact that a photon wavelength changes according to local gravitational potential may have been confirmed, but not the *assumption* that they gain or lose energy in the process. So you disagree with E=hf? Or with f=c/lambda? If you don't disagree with both, then you get E=hc/lambda, i.e. every change in wavelength is equivalent to a change in energy. This is not a scenario where those equations necessarily apply. Which one of these two do not apply, and why not? I'm not convinced that the wavelengths undergo permanent change. So you think they change only temporarily, and some time later magically return to their original values, or what? Consider this; Two adjacent straight lengths of equally spaced billiard balls, labeled (1) and (2), are set in motion along the line of their pointing direction. That has little to do with photons and light. I notice you choose to ignore that. Train (1) travels a straight line through free space while train (2) is set to run the gauntlet of a deepening gravitational potential well. Along the journey to the deepest part of the well on (2)'s travels, space-time will be stretching and will of course extend its train length. But because the well is still deepening, (2)'s departure from the well will be further restrained than if the well was constant. However, when (1) and (2) are returned to the same space-time environment they will still measure the same length. I'm not entirely sure what scenario you propose here. Does train (2) go down the well and then up again, or only down? Why should they? Every one of the billiard balls have been equally affected by the deepening well, so when the train emerges to compare with train (1), the distance between the balls must still be the same. But there is one major difference. The speed of train (2) will have slowed. Momentum is lost and that loss must be accounted for. The energy has obviously been used up in restraining the increasing well depth. Sorry, I have no clue what you mean with the last sentence. If the balls are replaced with photons Bad idea. Photons do not behave like billiard balls in most circumstances. which simply follow the changing geodesic path set up by the deepening well, it would be a mind boggling challenge to explain why they would shift further apart No one says that the photons shift further apart. Every individual photon loses some energy. (especially if they don't have wavelength????) Photons indeed dont have wavelength. Only the corresponding electromagnetic wave has. in order to overcome a potential momentum change that can't possibly exist. Are you quite sure that the Sachs-Wolfe effect is valid,,,, in any circumstance? Yes. Not wishing to break from the subject, but the concept of photons as particles has no place in the zero origin universe. Well, then how do you explain the photo effect and the Compton effect? (quantitatively!) There does seem to be a case for point source shafts of E/M radiation. "point source shafts"??? The reaction wavelength will of course remain as it was created (relative to dimension along its travels) What is "reaction wavelength"? and so too will the energy carried over the wavelength. But it can't be described as a particle in the zero origin universe. Planck opened a Pandora's Box when he did that, in my opinion. You did address neither the photo nor the Compton effect. Big surprise. Bye, Bjoern |

Crossing the finish line is just a small part of running a marathon, and some people would say it's not even the most important part. Science evolves. There are always some things which are not completely understood. You seem to think that science should offer perfect explanations for everything with no refinement based on observation. The interaction between theory and observation is a crucial part of science, and usually occurs with no harm to the basic ideas of the underlying theories. Also, you need to present an alternative which is BETTER. I don't know of any conventional explanation for such high temperatures. The lack of your knowledge is not a reason for other people to give up the big-bang theory.

Some people see the BBT as successful and useful - but I don't. I see it as a huge ship doomed from the start - but with passengers and crew so transfixed by the size of the vessel, its long history and the good company they are in to recognise how the theory fails to explain things which really must be understood, if the theory is to be regarded as being as reliable as the proponents seem to think it is. I don't see how anyone can take the BBT seriously, in principle or especially in terms of these supposedly very precise quantitative estimates of the Hubble "constant", the "age" of the Universe (13.7 +/- 0.2 = 1.5%), when the BBT proponents have no proper explanations for some phenomena (or at least observations we reasonably conclude reflect phenomena) which seem to be crucial to any understanding of stars, galaxies and large-scale structure. I have already mentioned the failure to find the Transverse Proximity Effect with a foreground quasar. This is an acid test of the BBT. If the BBT is true, and unless quasars are much shorter lived, more intermittent or narrowly beamed than any other observations indicate, then the effect would be observed. The researchers fully expected to find it, and they didn't. If they had, I would have been highly inclined to abandon my critique of the BBT, if this particular prediction was observed. This is a quantitative prediction - about where exactly in a spectrum some absorption will not occur. There's no room in the BBT for the absorption to be found or not found at any other part of the spectrum of the background quasar. Finding this lack of absorption, in a number of objects, would be so impressive. If I remember correctly, someone did point to a paper that reported seeing this lack of absorption. However, what is more important here is to keep in mind that the presence of the absorption can be seen as a problem for any model that predicts that the redshift is a distance estimator, and therefore it is also a problem for any "tired light cosmology". The high redshift seemingly old galaxy clusters is likewise another acid test - unless galaxy formation theory is contorted into ever shorter periods of time. Since our current understanding of galaxy formation is still very primitive, it would not surprise me if we find in the future that there is a mechanism that forms galaxies faster than we currently think is possible. Here are some other important phenomena / observations I think the BBT proponents have so far failed to satisfactorily explain: The intergalactic medium (IGM) emitting X-rays which can best be explained by extraordinarily high temperatures, such as 440,000,000 Kelvin: Field, G.

E. et al. 1980 The diffuse X-ray background spectrum from 3 to 50 keV. ApJ vol. 235, Jan. 1, 1980, p. 4-10. http://adsabs.harvard.edu/cgi-bin/np...pJ...235....4M I don't know of any conventional explanation for such high temperatures. (My theory is that it is heated by starlight etc. due to some redshift and/or scattering process which is not yet properly recognised. It can't easily radiate the energy, except by getting to such high temperatures, because it is so sparse that the particles rarely get close enough to emit bremsstrahlung.) Stars surfaces are only a fraction of this temperature. We can't even explain 1 Mega Kelvin temperatures in our own Sun's corona - and the most popular conventional explanations of that are based on magnetic waves, which clearly can't work out into the IGM, if only because it is such a lousy conductor due to it being so thin. Your information is seriously outdated. For the last ten years it has been understood that most of the X-ray background comes from obscured active galaxies/quasars, and not from a diffuse intergalactic gas. Why galaxy clusters in no way resemble the shape of gravitationally bound collapsing systems, such as galaxies or our solar system. The universe is only 14 billion years old, so the clusters have not had time to virialise, settle down into the shape that you expect for an old system. Why the galaxy clusters often are stretched out in space and resemble liquid squeezed into the gaps between generally spherical bubbles. (I suggest that the void IGM is so hot that it is of sufficient pressure, which is probably very low, to corral the galaxies into the smallish clusters.) Due to the way the matter was distributed from the beginning, the collapse may have proceeded faster in one direction than in the other directions. That will inevitably lead to that it will collapse into a pancake shape. Why galaxies don't so often come close to each other. (I figure that galaxies are exuding a corona which pushes others away. Exactly how the mass of the galaxy is coupled to this in an aerodynamic fashion, I am not sure, but a rough guess is that most of the mass is in black-dwarfs and their potentially numerous and relatively small collision fragments, which would have a fair bit of drag. I am not sure how anything could push a star around to a significant degree, by gas pressure in the surrounding medium, but maybe not much pushing is required. Maybe none is required if the visible stars are gravitationally bound to the larger mass of black-dwarf fragments which are themselves coupled to the corona of the galaxy.) As a matter of fact galaxies come close to each other. We have observed plenty of interacting and even colliding galaxies by now. Actually we now think that the mergers of galaxies played an important role in the early evolution of the galaxies. The extra mass in spiral galaxies which presumably causes the observed visible stellar rotation curves. Yes, this is an interesting topic, and it has been discussed in other threads on this newsgroup recently. The heating and acceleration of stellar coronae and winds. http://astroneu.com/plasma-redshift-1/#Cranmer Likewise the nature of solar spicules, the heating and acceleration of prominences etc. These are very interesting problems in my opinion, and many good researchers are working on them, but they do not have any impact on cosmology. A whole bunch of things about quasars and AGN: Why they vary so fast when according to the BBT they are impossibly large, due to their supposedly high output, based solely on their distance being according to the BBT interpretation of redshift. No, quasars are not impossibly large, though they are very bright. As a matter of fact the black hole which is driving the activity in the interior of the quasar has a radius of around a billion kilometers, and would fit inside our solar system The nature of jets. Another interesting problem, which is completely unrelated to the big bang theory. How, if as according to the BBT, there used to be lots of quasars etc. why there aren't similarly massive and luminous objects around the place today, such as in the middle of galaxies. The centres of most galaxies seem to harbour massive black holes, but today they are usually quiescent. Supposedly because there is not enough gas around them to fuel the activity. My best guess would be that the remaining gas has been used up in forming the stars of the galaxies. The CMB. While the BBT has an explanation for the CMB, I don't think it is the only possible explanation, as I have written in previous messages in this thread. There may be other mechanisms, but they have a very serious problem in forming a spectrum which is sufficiently close to the theoretical black body spectrum. I know its a big task to develop cosmological theories. The BBT is fine as a theory, but I see so many problems with it that I can't take it seriously. Other folk don't seem to see or care about the problems I think are significant - but to me, the BBT really looks like a great overblown and entirely wrong theory which will soon be discredited. The key, I think, is coming up with a good in-principle - and yes Bjoern, Quantitative - theory of the redshift we observe in stars, galaxies and AGN. Well, other people know that the problems you mention do not exist or are not related to the big bang. I am on the case, but I think the first task is to overcome the problems caused by thinking of electromagnetic radiation and the quanta of energy which result from it as involving independent "photons". Good luck, but such a theory will immediately be in conflict with established experiments like the photoelectric effect and Compton scattering. If you cannot resolve these conflicts nobody will pay any attention to your theory. [snipping a short discussion on cosmological supernovae] Ulf Torkelsson |

I'm expanding on this part of my recent post, if I may.
The all sky picture of the universe from the zero origin is crystal clear. According to that picture, matter is slowly clumping together, That's the same as the BBT says. increasing the depth of dimension, of space. Bjoern Feuerbacher wrote: That's incomprehensible. I replied: Exactly. That's what I've been trying to tell you all along. -------- I hope you're ready for this. First of all, Pound an Rebka demonstrated, only, that the frequency of the characteristic rays emitted from a radioactive iron sample at the bottom of the tower was slower than when it was shifted to the top of the tower. If both (top and bottom) measurements were taken at the top, or at the bottom, of the tower the discrepancy between them should still be exactly the same. The apparent redshift caused by the climb from the bottom of the tower was then already there when it began the climb. If that has already been noted, or perhaps has gone un-noticed, it confirms or can confirm the existence of the zero origin universe. But the Mossbauer effect, which I know very little about, is probably not capable of performing the required task. The Pound and Rebka experiment was always my key evidence that the depth of dimension varies according to local matter content. But every attempt at describing this variable dimension, that nobody can comprehend, naturally always ends up in a comprehension nightmare. I've never succeeded in satisfactorily explaining this, even to myself. The comprehension nightmare doesn't end here either. I was hoping to use a failed Sachs-Wolfe effect as a springboard to help with this latest, very brief, explanation. Each characteristic wavelength emitted from its parent material in a gravity well was created from some kind of charged particle interaction. The interaction rate, and consequent wavelength creation process, is slowed because the interactive components have been stretched further apart. And there's no limit to how far the stretch can go. That added depth of dimension does not exist to an observer outside the well because it's created by an increased speed of light, which takes it beyond the realm of the outsider's existence rate. Neither the added dimension nor the increase in the speed of light will be noted. Matter collects together in a gravity well and thus becomes further apart. How am I supposed to explain that? In my web page description of the zero origin universe, I've sidestepped this and other such questions to some degree, hence my tendency to waffle on in those areas. I had no other choice at the time, and probably still don't. ----- Max Keon |

[snip most - other people have addressed that already well] Once there is a good redshift theory - especially one we can test in space or on Earth - then the only remaining task to deal with is the BBT supporter's interpretation of supernovae light curves, which are conventionally understood to show time dilation. Jerry Jensen's critique looks like a good starting point: http://arxiv.org/abs/astro-ph/0404207 You really think that is a good starting point? Jerry Jensen 1) uses scatter plots for which he himself admits that the fit to the line he uses isn't very good, and just looking at the graphs shows nicely how bad it actually is. 2) claims that a Malmquist type II bias could account for the data. But articles examining time dilation of SN light curves already discuss such a bias and come to the conclusion that it can't explain the data. See e.g. section 5.3 of astro-ph/0309368. 3) claims that SNIc could be mistaken for SNIa. But that possibility is also taken into account by the SN researchers (see e.g. section 5.2 of astro-ph/0309368). And Mr. Jensen does not explain where all the SNIa are if all or most of the observed SNs are really SNIc. 4) His note 1 (page 28) shows that he misunderstood both the results of the SN study of Riess (2004) and the implications for the theory. He claims that according to Riess et al, the universe has stopped expanding some time ago (at the highest redshifts) and started to contract. In fact, what Riess et al. found was that the universe was always expanding, but in the beginning that expansion was decelerating and only some billion years ago it began to accelerate. And that's *exactly* what the Lambda CDM model predicts! I did not bother to look at all of Jensen's article; but the four points above are already enough to relegate it to the dustbin.

Each characteristic wavelength emitted from its parent material in a gravity well was created from some kind of charged particle interaction. The interaction rate, and consequent wavelength creation process, is slowed because the interactive components have been stretched further apart. You don't know much about emission of radiation by atoms, right? And there's no limit to how far the stretch can go. That added depth of dimension What does that mean? does not exist to an observer outside the well because it's created by an increased speed of light, Please present evidence that the speed of light increases in a "gravity well". Actual observational evidence seems to say otherwise (ever heard of Shapiro?). which takes it beyond the realm of the outsider's existence rate. And what on earth is *that* supposed to mean? Neither the added dimension nor the increase in the speed of light will be noted. How convenient: a prediction of your model which can't be tested in any way. Matter collects together in a gravity well and thus becomes further apart. Pardon? Collecting together means becoming further apart to you? How am I supposed to explain that? In my web page description of the zero origin universe, I've sidestepped this and other such questions to some degree, hence my tendency to waffle on in those areas. I had no other choice at the time, and probably still don't. So far, you waffle in *every single area* I want you to address. Bye, Bjoern |

What would a large galaxy cluster look like after it has virialized? A huge "elliptical" made up of galaxies? Or would the individual galaxies merge before virialization could occur? On larger scales, a filament made up of thousands of galaxies could presumably be considered a 1-dimensional structure - would that collapse, and what would it look like afterwords? Just curious... |
