Their origination as singular and randomly far-placed objects precludes the galactic star-birth mechanism. They have haphazardly built an inner energy nest and succumb to it. The outer halo stars are of a different genesis scale to the interior just as quasars are of a different genesis scale and may be the halo progenitors of this universe. |

RKS: Dark Energy; Dark Matter; Inflation theory (all); SuperSymmetry (all); etc You mean your bull**** meter lasted through that lot only to fall on his rant? One evidence free theory is enough for physics. So which attacks of imaginatice should be culled first? As the current Big Bang model (Lambda CDM) relies on unproved Dark Matter and Dark Energy theories, Grand Unifying Theories which rely on unproved SuperSymmetry theory,I say we cull that one first. And this is what physics has become: 1) Current theory doesn't work so: 2) Make up something that fits the gap eg Inflation, Dark Matter, Dark Energy, SuperSymmetry; 3) Hide the fact that you made up the theory by relating it to current theory mathematically; 4) Make the mathematical model predict the universe that we already know is present ie actually predict nothing at all; 5) Pretend that the initial contrivance was a discovery. Had we started off with a chicken little theory instead of the Big Bang then 'Sky Falling' theory would have been proved and all researchers would be in agreement - eg the falling sky can be measured as cosmic rays. You see we can always make unrelated data fit whatever crazy models we dream up. Even though half the CMBR measured in shadow effect observations was generated locally we persist in insisting that it all came from a period shortly after the Big Bang. And the fact that time is slowed by cosmic redshift (Redshift of light from distant objects) we ignore this when calculating the age the of the universe as I demonstrated in a previous message. And the response from the 'experts'? If I don't agree with current models it is because I haven't read enough papers, even though the question I have been asking are probably not in any papers. But if I go off on a wild goose chase then at least I stop poking holes in current models by asking questions (something that is fast becoming a forbidden heresy). Robert |

And this is what physics has become: 1) Current theory doesn't work so: Except it does. 2) Make up something that fits the gap eg Inflation, Dark Matter, Dark Energy, SuperSymmetry; Supersymmetry isn't even thought to be real - try again with the buzzword generator. It must bug you that physics has essentially made **** up and it has worked out well. RKS: Not one of the many proposed experiments suggested by string theorists (Supersymmetry theory) that have been carried out have had positive results. Or have you conveniently forgotten about the detectors down mine shafts and other misadventures? Physics works well. But Cosmology has become a joke. Let's list a few predictions that have recently failed: The ripples in the CMBR were less than 1/10,000 the magnitude of any generally accepted model; the expansion of the universe is not slowing; the expected shadow effect in the CMBR was only found in half the galaxies observed; the most distant objects ever observed turned out to be old galaxies when they were expected to be young (as the universe was young); 3) Hide the fact that you made up the theory by relating it to current theory mathematically; Every theory is made up. RKS: No, hypotheses are postulated based on extrapolations of current theory and/or observation. There are no such observations for string theory - it is contrived from whole cloth, like a science fiction novel only less plausible. Dark Matter and Dark energy are treated like theory although they are only somewhat speculative hypotheses. There is no evidence of inflation - it was contrived from whole cloth. 4) Make the mathematical model predict the universe that we already know is present ie actually predict nothing at all; Except when it predicts new things, eg - noninteracting matter that was discovered through lensing in the bullet cluster. Ooops. RKS: Not everyone agrees: But now the whole dark matter theory - together with aspects of Newton's and Einstein's theories too - are being questioned by two Canadian researchers in a paper soon to be published by Britain's prestigious Royal Astronomical Society. The challenge has come from graduate student, Joel Brownstein and his supervisor, Professor John Moffat of the University of Waterloo's Perimeter Institute for Theoretical Physics. The two have based their new theory on observations of the so-called "Bullet Cluster" of galaxies - 3 billion light years from Earth and renowned among astronomers as being the site of the "most energetic event known in the universe since the Big Bang". In fact the Bullet Cluster in the southern constellation of Carina is where two huge clusters of galaxies have actually collided. Last year NASA scientists used the same Bullet Cluster and the photos taken of it to put forward "direct proof" that dark matter exists. Now the Canadians have analysed the same images and come to a totally different conclusion. http://www.sciencewa.net.au/index.ph...nt&ta sk=view http://arxiv.org/abs/astro-ph/0702146 But what of Dark Energy? That appears to be pure wishful thinking. And what next - Dark Time??? Robert |

But now the whole dark matter theory - together with aspects of Newton's and Einstein's theories too - are being questioned by two Canadian researchers in a paper soon to be published by Britain's prestigious Royal Astronomical Society. Ah, MNRAS. Could be worth something. The challenge has come from graduate student, Joel Brownstein and his supervisor, Professor John Moffat of the University of Waterloo's Perimeter Institute for Theoretical Physics. Brownstein and Moffat? Ohh, if only I could guess! These two have a specific axe to grind as TeVeS is their baby. Always view claims like this with suspicion. I can count the number of independing confirmations of their claims with no fingers on my hand. The two have based their new theory on observations of the so-called "Bullet Cluster" of galaxies - 3 billion light years from Earth and renowned among astronomers as being the site of the "most energetic event known in the universe since the Big Bang". I find this to be a curious claim because the average supernova is more energetic than the bullet cluster. Chalk this up to baaaaaad writing. In fact the Bullet Cluster in the southern constellation of Carina is where two huge clusters of galaxies have actually collided. WHAM! Chuck Liddel ain't got nothing on that! Last year NASA scientists used the same Bullet Cluster and the photos taken of it to put forward "direct proof" that dark matter exists. Where "last year" is actually 2006. Now the Canadians have analysed the same images and come to a totally different conclusion. Hand it to dead cat and you get a third. http://www.sciencewa.net.au/index.ph...5&option=com_c... http://arxiv.org/abs/astro-ph/0702146 I'll never understand why folks who so badly want to be rid of dark (energy|matter) are so quick to hop onto another theory that does the same thing but WORSE. The invocation of a handful of arbitrary field can predict just about anything you want. I am amused at the inclusion of a Yukawa based description of gravitation in the derivation...well derivation is the wrong way to put it as the equation was just dropped in. Anyway, Yukawa based potentials have been rather tightly constrained in planetary motion and by lunar ranging. Not much [any] attention has been dedicated to that, but I expect an explanation by arbitrarily saying 'it doesn't have an effect at solar-system scales'. Read the last two pages of the paper. It isn't that convincing. But what of Dark Energy? *That appears to be pure wishful thinking. And what next - Dark Time??? Robert |

Three if you count the more complicated example of Abell 520. Just a coincidence, right? So what's the stuff we call dark matter? RKS: It is the abundant dark matter beyond the known dark stuff that is enigmatic. We have always known about burnt out stars, gas and dust that floats about the place and does not emit any light. It may be the one hypothesis that turns out to be really interesting, but arrayed with all the other guesses... One of the problems with the dark matter hypothesis is that with all that dark matter about the visible universe has more than enough mass to form a Schwarzschild black hole. If we array a set of so called coordinate clocks across a Schwarzschild black hole then we note that clocks ever closer to the centre appear to run ever slower. If one was near the centre then one notices that clocks ever further away appear to run ever quicker. This means that light coming from an ever greater distance to a central observer sees light ever more BLUE shifted. Now this is obviously the opposite to what we observe. However, if the universe were infinite then from any point in that universe one must be at the event horizon of a Schwarzschild radius as there is more than enough mass in any direction to form a Schwarzschild black hole. Now when we array our clocks as before we note that clocks run slower the further away from the observer they are placed and light coming from ever greater distance is ever more redshifted. This is precisely what we actually observe. The one aspect of this simple, but consistent with all observational data, model is that spacetime curvature is relative ie spacetime curvature on the very large scale depends on where the observer is. Oddly enough, General Relativists don't like relativity of space-time curvature. But look what they have to make up to work around it - Big Bangs, inflation, Dark Energy etc. Occam should razor that lot for sure. Let's list a few predictions that have recently failed: The ripples in the CMBR were less than 1/10,000 the magnitude of any generally accepted model; ....which is why inflation was invoked to explain this, and explain why parts of the CMBR which correspond to parts of the universe that have never been casually connected just happen to share the same features. RKS: Inflation had been around for more than ten years, but cosmologists rightly treated it like the joke it is. It is only when there was nothing left in the theory closet that it was incorporated into any models, ending with the current Lambda CDM (CDM=Cold Dark Matter) the expansion of the universe is not slowing; In fact, it is speeding up. Reading is fundamental. RKS: I'm aware of one of the major discoveries of the 1990s. It is the accelerating expansion that led to Dark Energy hypothesis. Note that no-one thought that the current model might be wrong. Oh no, perish the thought. We just have to make up some new force or stuff or phenomena that we must have missed. If religionists had been that persistent we would still be holding to 'Biblical Truths' ~ maybe 'Dark Time' could have solved the disparity between the biblical creation and observation of the universe? Maybe God uses Dark Energy to his work? At least science bothers to check their contrivances. the expected shadow effect in the CMBR was only found in half the galaxies observed; ....in first year WMAP data under the assumption of isothermal galaxies. The analysis has yet to be repeated and you have yet to explain why the falsification of the obviously-wrong isothermal galaxy model is a disproof of the big bang theory. RKS: Firstly, there is no 'Big Bang theory'. There have been a set of hypotheses purporting to model the evolution of the universe. One of the most notable was Gamow's model which predicted a fossil infra red and microwave radiation. Gamow himself predicted that the radiation would be around 20K. The CMBR was discovered, but at much lower temperature. The infra red guess proved to be wrong. Gamow's model failed, as did the subsequent models. The model we currently have is the Lambda CDM which hails from the mid 90s ie is a bit over ten years old. The Lambda CDM also predicts that Cosmic Microwave Background radiation is emitted at some period after the Big Bang, which is the name that Fred Hoyle gave Gamow's model. If the CMBR was emitted at that time then it must have travelled across the universe to reach detectors on/near Earth. If there are galaxies in the way then there should be a shadow effect. In 2007 it was discovered that there was no shadow effect for half the galaxies surveyed, indicating that the CMBR detected must have been emitted somewhere between the observer here on Earth and that galaxy. In fact there are galaxies all over the place. In a reverse of the infamous Olber's paradox, the CMBR should be riddled with shadows, most of which are missing... the most distant objects ever observed turned out to be old galaxies when they were expected to be young (as the universe was young); So? RKS: That would have been enough to sink any model that opposed the Big Bang, had they postulated it. But the BB theory we have "So?". You make a prediction, all the observations contradict it. OK. The Bullet cluster appears to show evidence of dark matter. So? When it is played back to you, it doesn't look so clever, does it... Dark Matter and Dark energy are treated like theory although they are only somewhat speculative hypotheses. Except they both have specific mathematical models with abundances of theoretical and observational motivation. RKS: Let's not lower the standard for cosmology hypotheses. If there is enough there to take them seriously then pursue them, by all means. But let's not consider them a done deal just yet. I note that there are far more scientists prepared to accept Dark Matter than Dark Energy. I note that you are no fan of string theory. If so, then how do you account for the fact that inflation relies on the GUT which in turn relies on string theory? Well, Guth's version did. I'm not sure what the Lambda CDM has cooked up on the GUT front. And doesn't the whole big bang/inflation model depend on the unification of the four forces...gravity not playing ball??? There is no evidence of inflation - it was contrived from whole cloth. There's an entire group of astrophysicists who would love to hear the much more physically plausible explanation that's consistent with observation. I personally cannot wait to see the paper you wrote on the subject - do you have a reference handy? Or is this armchair guessing like so many others? RKS: I was asking questions...I seem to have diverged a little. Anyway, as you have refused to answer what you claim are simple questions (in another thread) and are even now asking questions yourself, it seems only fair that I make up a model as well. I'll go with the infinite universe and the relative space curvature model. As for galaxy rotation - I asked a few questions. For instance, I read about the enigmatic rotational motion of spiral galaxies. I assume that globular clusters are not mysterious in this regard? Is the ring galaxy's rotational motion also mysterious or is it just spirals and I assume barred galaxies as well? 4) Make the mathematical model predict the universe that we already know is present ie actually predict nothing at all; Except when it predicts new things, eg - noninteracting matter that was discovered through lensing in the bullet cluster. Ooops. RKS: Not everyone agrees: Not everyone agrees that the Earth is round. That's not sufficient. RKS: The earth isn't round - it's ellipsoid. But apparently my observation is not sufficient for you...?? Last year NASA scientists used the same Bullet Cluster and the photos taken of it to put forward "direct proof" that dark matter exists. Where "last year" is actually 2006. RKS: The article date is 2007...you were saying about 'reading'?? I'll never understand why folks who so badly want to be rid of dark (energy|matter) are so quick to hop onto another theory that does the same thing but WORSE. The invocation of a handful of arbitrary field can predict just about anything you want. I am amused at the inclusion of a Yukawa based description of gravitation in the derivation...well derivation is the wrong way to put it as the equation was just dropped in. Anyway, Yukawa based potentials have been rather tightly constrained in planetary motion and by lunar ranging. Not much [any] attention has been dedicated to that, but I expect an explanation by arbitrarily saying 'it doesn't have an effect at solar-system scales'. Read the last two pages of the paper. It isn't that convincing. RKS: I was pointing out that not everyone agreed. Yes, when there is nothing but two flaky theories to choose from... Let's hope they establish or dismiss the dark matter question expediently so we can move on to more interesting questions, like why the visible universe isn't a Schwarzschild black hole...not enough mass without the dark stuff Oh, and I have a bunny in the hole for Dark Matter ~ it is what happens to black holes...we can't have 'Periods' (as in analogous to the punctuation mark) spotted around an infinite universe, there must be some kind of 'life cycle'. Tiny little singularities from a cold explosion - invisible dust that radiates through a galaxy and accumulates in the halo where it eventually decays into ordinary matter. Robert |

That is criticism that needs to be resolved one way or the other, but neither you or I can do it. There needs to be follow-up study of the data to resolve the issue. In the meantime, you interpret the data as showing nothing, I don't. For instance, were all the galaxies that did cast a shadow of a demonstrably different type to those that didn't? I don't know, do you? I don't see how that amounts to being a crank. Robert |
