I have see nothing in the Big Bang model making that kind of predictionIE( filamentary stucture) even for the Dark Matter, they talk after the fact of that structure and assimilate it with DM. <font size=-1>[ This Message was edited by: Orion38 on 2002-11-25 18:18 ]</font> |

For sure, I agree on your kind of reasoning, that we should up to some point, try to distinguish ourselves from the outcomes of what we observe. The universe is what it looks to be, based on observations in combinations with natural laws. Observations alone don't tell us of course, the universe started in a Big Bang. Only if we adopt to some cosmological model, this becomes the outcome of the observations. BB theory is of course not born as sort of creation myth, but was established the other way around, based on solid science. At least, that is what we believe, science is doing, although it has encompassed some absurd elements in fields like quantum mechanics and other fields. Up to a certain point I can agree on that. But let us also clearify, that nature is not a mathematical equation, and one should distinguish between outcomes of mathematical equations and nature itself. You are right when you say that I haven't adressed or come up with real evidence here that shows Big Bang theory isn't right. I don't expect anyone to "buy" what my instinct says about how the universe or nature should be. Of course not. I am just explaining my thoughts on why I eventually would think, that BB theory on the long run would have to be replaced by another theory. And I think some elements of this, have been worked out already by a number of scientists. Maybe they are laughed at at this very moment by most of the scientific community, because their work doesn't compromise with the current theory. But I think they are looking in the right direction, and eventually, something will come out that indeed can replace Big Bang theory. Maybe I am wrong, but my intuition just tells me that Big Bang theory must be replaced some day. The pitfalls of Big Bang theory to be mentioned are, they encompass too many parameters. I think a theory that doesn't have so many parameters, does a better job in explaining. At least one can say to my knowledge is that not all research should be going to just one theory. I think there is enough challenge ahead, and it might turn out, our picture of the universe in the long run, could be totally different then what we conceive now. |

2)-And you dont adress the fact that the light is affected by that structure. Here is the prediction by a hero of mine: http://public.lanl.gov/alp/plasma/pl...rse.intro.html In 1950 Hannes AlfvÈn, Nicolai Herlofson, and Karl Kiepenheuer brought this form of plasma radiation to astronomer's attention. Alfvén, who later won a Nobel prize in physics for his solar studies, proposed hat streams of electrons move at nearly the speed of light along magnetic-field lines not only in Earth's magnetosphere and above the Sun, but also through the cosmos. If so, sheets and ropes of electric current should crisscross the universe in ever-increasing sizes... These currents, Alfvén thought, should give the universe a cellular and filamentary structure. At the time of this suggestion, supporting evidence in the form of huge filaments, sheets, and walls of galaxies were unknown. <font size=-1>[ This Message was edited by: Orion38 on 2002-11-25 19:46 ]</font> |

Tired light has been shot out of the water already in this thread.
The gravitational redshift effect is too small for the energy density of our universe. Of course, neither of these ideas are covered in the links you provided. Next? |

http://www.cfht.hawaii.edu/News/Lens...Sliceshear.jpg Image of the distant galaxies lensed by the dark matter of the universe This view shows what the observer at the front of the box would percieve when looking at galaxies in the sky. The blue elongated disks are the images of distant galaxies formed by their light after it has passed through the box. The observer can see these galaxies but the filaments of dark matter, shown here in red and white, are invisible, even to the largest telescopes available to our observer. **However, one can see that the galaxy images are **elongated in a special way** on average: they are **stretched** along a direction parallel to the filaments of dark matter. **This effect is a consequence of gravitational lensing which stretches the tight bundle of light rays from a single galaxy much like the moon's gravity stretches the Earth to cause the ocean tides**. By measuring the** systematic distortion** in the images of distant galaxies**, one can "see" the dark matter.

As long as we didn't find it and proof that such another mechanism exists, we must agree on the doppler-redshift interpretation. But I am not absolutely sure, that no alternative for the redshift can be found. Quote:

It is healthy to science, when also scientific work besides the mainstream can be done. I am not defending creationist science, cause calling something science is not what it is about. And it's sure the case they defend is lost. But up to a certain point they just do science critique, and I would think that such a thing should be allowed. Science is not just the realms for the well educated, it is also something of societal interest. The debate about science is something which is necessary for societal reasons. One should also realize that the billions of dollars going into scientific research, like astronomy and theoretical physics and such, must be justified for the whole of humanity. Grand part of humanity doesn't even have access to proper education. Quote:

I like to make some remarks, just for the sake of having this discussion going somewhere. First of all I respect your remarks, which clarifies why you see the things you see, and why you think the Big Bang theory is right. Your conclusion is based on the scientific discoveries and observations, and which doesn't allow you to say otherwise then to defend the BB theory. In principle the reality and the things that BB theory are based on, are same for you as for me, and I don't think our reasoning is that different, that we could conclude differently. Well, our level of understanding might be different, and also our knowledge, but if we would both be on the same level, that would be quite sure. And in fact I did not state otherwise then saying that based on what is gathered upto now, the BB theory has most credits. I haven't been denying that. All I was trying to say is that, even if the BB theory looks convincing, I do not conclude up to this point that in the near future we might establish quite a different perspective on this issue. It's a conclusion I draw on mere instinct and intuitive reasoning, then based on facts. Something tells me, some pieces are missing from the puzzle. I have explained why I was thinking that way, because it would make the "universe" a non self-contained entity, and of which the causes most probably would reside in an (unknown) "super-nature". That conclusion I am not willing to make, cause I think there is a lot more out there, that has not been discovered and analyzed, and which might be of crucial interest to explain the universe as we see it. It must be, cause else I think, science has lost its mind, and isn't realy able to understand the reality/universe, without the help of something "supernatural". Ultimately, if it would show up, that the universe can't be explained otherwise as the BB theory, there is where we are going to, in some or other way. I think that what distantiates us in this respect is not just the knowledge or reasoning on a scientific level, although I assume you are better skilled on cosmological issues then I am. What distantiates us is that you, when seeing the whole picture, accept it as it is, while I cannot accept it as it is, and merely conclude that something must be missing. It might turn out I am right, and we can conclude convincingly that what we see is a distorted image, because we neglected some things, or weren't even aware what the causes were. The proof is in the evidence of course. I am not asking anyone, without the proof/evidence delivered, to "buy" this, or to drop the BB theory instantly. Science asks us to only conclude things, based on observed evidence, on not to go for instincts or intuition. That would be just silly. Science is indeed not a mere replacement for religion, it stands on totally different grounds. Nevertheless, scientists are people, with certain convictions, which makes them think differently, even when sharing the same kind of knowledge and observational evidence. Science in total, is not a rational process. We may think it is, but the portion of irrationality has often be part of the scientific research. If we would just leave our current understanding at the level it is now, no progress could ever be made. It may turn out, we are looking in the wrong direction when we go beyond what is commonly believed or hold for truth. But it may turn out we are looking in a direction, nobody had searched before, and find something that tumbles down our previous conceptions. I hope you see, that is just the kind of argument I was making. Untill now and at this point of knowledge and evidence, what I say can't be justified. I am aware of that. But someday, it might turn out my intuition about this was right. You may call people who do not completely accept the mainstraim ideas lunatics, or whatever you prefer. History has shown that every new discovery, that challenged the current belief, was at first not accepted. That is just the way it is, and probably will always be the case. And in itself it is quite understandable. If you trust the science in the way they established their evidence, it would be silly to give that up, untill evidence is provided and established in way, good science practice prescribes. The way I am reasoning, you may call irrational, and not based on evidence. I do admit that, and I layed out why I, despite the evidence for the contrary, think that way. Untill more reasearch in this field has been done, and scientific evidence is provided, I expect noone to go for it merits yet. We have yet to see who is right and who is wrong. And I accuse noone, who has settled for the current mainstream ideas and theories in cosmology, of having established something out of the ordinary, if it turns out that the BB theory wasn't right. It's just the way science progresses. <font size=-1>[ This Message was edited by: heusdens on 2002-11-26 09:55 ]</font> |

Well, heusdens, you've succeeding in posting two posts in this thread that haven't contained many egregious factual errors, and for that you should be commended. It is very important that you clearly separate out your own personal biases from that of scientific observations and theory. If you maintain a clear demarcation between these two realms, you won't cause much of a rukus.
I must concede that your point of view cannot be disputed on purely logical or philosophical grounds. You seem to want validation that "you might be right". I think I have given as much validation to the areas where you "might be right" that I can. There's only so much bending over backwards that I am willing to do for someone who has a gut feeling about the way the universe should be and draws conclusions about reality based on that. As I said, why should I believe your theory any more than say, Ragnarok's Impending Solar Feast? Once I abandon my scientific standards, I am left to the wiles of mythology and gut instinct. |

Science is rational, but the process of science how it evolves, is not. There is no reason why you should believe me. There is no reason to believe anything, apart from hard facts. But a good dosis of scepticism and good instinct, are sometimes necessary. Look at it this way. Suppose you see a good magic show. In this magic show, things are occuring, of which you know, can't happen. You know there is a trick or that you are tricked. But you don't know how the trick was performed, and no matter how hard you try to find out, you don't succeed. What do you conclude, there was no trick but "magic" happened, or that it is explainable in more ordinary terms, even when you did not discover the trick. I assume the outcome to be of the "cosmic puzzle" to be, that there is logically and reasonable explenation that can be given for the way we see the cosmos. I don't go for the alternative that "magic has happened". But anyone may choose as one likes. |

But your alternative is just as magical. Apart from mundane arguments about us being here, there's no a priori reason to assume that existence should occur. It's just as much "magic" even if there is no intial point of time and space.

It would be to think that "non-existence" or the "nothingness" could "exist" and would have been an alternative to the existing universe. The universe didn't appear out of nothing, and wasn't caused by something, it simply existed/exists, and will go on to exist. There's only one way in which one can derive the conclusion that "something" must have caused the universe to become existent, and that is to think that "non-existence" or the "nothingness" could have had existence, which would neccisitate for the universe to get into existence (since, ultimately, we are here). Unless you are willing to give up it's formal definition, in which "nothing" does have existence of it's own, and suddenly becomes "something that exist", and could be an alternative for everything that exist. Well, we must understand that this is one of the basic layers of our consciousness and concepts about the world. If in our mind, we do not completely understand this issue, then I very much doubt if one can come up with a good scientific explenation of all of reality. I know, like you are infringing to say, that the way we arrive at this conclusion, is like magic, but ultimately I don't think it is magic after all. I myself, didn't arrive at this conclusion by studying science, by looking at the cosmos, or by reading philosophic work. I was ample going to school, when thinking about this one issue, so I guess I was not influenced or pre-biased in answerhing this question: why is there a world, instead of no world at all. The conclusion of this self-debate, I already gave you. But it's a good and hard question to start with, and I could advice anyone, if they haven't alredy done so, to find and answer on this intruiging question one self. And try to avoid to be pre-biased, and more or less reformulate an answer cultural understanding provides for this one, but find the answer yourself. You can find that answer, without looking into the sky, or by studying anything material, but just by deepening this question, and use your logic skills, to tackle that question. |

Orion, Dark Matter interacts just the same as normal matter as far as gravity (and gravitational redshift) is concerned. It just doesn't appear to be luminous or otherwise interacting with normal matter.

Orion, that is indeed a wonderful site, as I have said before. It is not a disproof of doppler redshift, of course. In fact, it works based on the expanding universe to create the model.
