Science/Tech See other Science/Tech Articles Title: The Picture that Won’t Go Away (Big Bang Has Burst) Only in the rarest instances has a single picture altered the direction of a scientific discipline. But in the case of the galaxy NGC 7319 and the "misplaced" quasar in front of it, the message is inescapable. Today we return to an image we have seen before. On October 1, 2004, our Picture of the Day included a high-resolution photograph of the nearby galaxy NGC 7319, taken by the Hubble Telescope. Seen in front of the dense galactic core was a quasar. Prevailing ideology did not permit a quasar to occupy that position, and its presence threatened to shatter one of the most cherished themes of mainstream astronomy: the Big Bang. For those who wonder what all the commotion was about, we offer this brief refresher. The rationale for the Big Bang rests substantially on an interpretation of a well-known phenomenon called redshift. The term refers to the shift of light from distant galaxies toward red on the light spectrum. Many years ago, astronomers decided that redshifted objects must be moving away from the observer, stretching out their lightwaves. This Doppler interpretation of redshift enabled astronomers, based on the degree of redshift, to calculate both the distances and velocities of the objects. From these calculations, certain conclusions were inescapable. If all redshifted objects are moving farther away, the universe must be expanding. If the universe is expanding, the expansion must have had a starting pointan unimaginable explosion producing a universe of galaxies receding in every direction from the observer. The Hubble Space Telescope Key Project has recently placed this event 13.7 billion years ago. The envisioned universe was not always so large. A sudden leap in its official size occurred with the discovery of quasars, the most "redshifted" objects in the heavens. These objects are so strongly shifted towards the red that the astronomers' scale put them outside the previously imagined boundaries. And being so far away, they must be vastly more luminous than any objects in existence today. These conclusions were, by the astronomers' own admissions, inescapable. And they became the foundation for modern cosmologythe so-called Queen of the Sciences. There were dissenters, however. Astronomer Halton Arp, the leading authority on peculiar galaxies, presented evidence that quasars are not extraordinarily bright objects at the outer edges of the universe. They are physically and energetically connected to the closest galaxies. Arp claimed that the universe is not expanding and there never was a Big Bang. For his dissent, he lost his telescope time and had to move to Germany to continue his work. Yet as we gained a better picture of remote space, evidence against the Big Bang continued to accumulate. When distant galaxies were plotted according to their redshift-determined distances, they appeared to be arranged in lines that pointed at Earththe so-called Fingers of God. Galaxies with greatly different redshifts but otherwise having similar forms increased tremendously in size with increasing redshift. And almost every nearby active galaxy was discovered to have a greater-than-average number of quasars nearby. Then came the Hubble photograph (above right), taken on October 3, 2003. The picture showed a galaxy (NGC 7319) known for its dense clouds that obstruct all objects behind its core. In front of the galaxy's core is a strongly redshifted quasar. In fact, under the prevailing assumptions, the redshift of the quasar would put it more than 90 times farther away from us than the big galaxy behind it. Also, as noted in our earlier Picture of the Day, Arp and his colleagues show that the quasar is interacting energetically with the material in front of the galaxy. The paper by Arp, et al., that announced the discovery may be viewed at: http://arxiv.org/abs/astro-ph/0409215. Hence, the standard suppositions about redshift do not work: The quasars redshift cannot be the effect of a velocity of recession or an expansion of the universeit is just an intrinsic, and yet unexplained, quality of the quasar. One might have expected alarm bells to go off within the astronomical community, since much of its funding rests on the assumed credibility of its theoretical starting point. But the responses have ranged from nonchalance to outright denial. Leading scientific institutions still issue news releases telling us that all is well in modern cosmology. One scientific publication after another continues to discuss the Big Bang as if it were an established fact. Public relations in the sciences did not always work this way. A quarter-century ago, when Americas favorite astronomer, Carl Sagan, published his book, Cosmos, he addressed the redshift question: "There is nevertheless a nagging suspicion among some astronomers, that all may not be right with the deduction, from the redshift of galaxies via the Doppler effect, that the universe is expanding. The astronomer Halton Arp has found enigmatic and disturbing cases where a galaxy and a quasar, or a pair of galaxies, that are in apparent physical association have very different redshifts...." Sagan's acknowledgment here showed a candor rarely found in standard treatments of astronomy today. He continued, "If Arp is right, the exotic mechanisms proposed to explain the energy source of distant quasarssupernova chain reactions, supermassive black holes and the like would prove unnecessary. Quasars need not then be very distant. But some other exotic mechanism will be required to explain the redshift. In either case, something very strange is going on in the depths of space." It is astonishing to realize that, for a quarter century after Sagan wrote these words, an ideological interpretation became increasingly entrenched in astronomy, even in the face of growing evidence to the contrary. Critics point to the demands of funding as the primary culprit. Recently, dozens of top scientists, including Halton Arp, Eric J. Lerner, and Michael Ibison authored an open letter to the scientific community, arguing that the dominance of big bang theory "rests more on funding decision than on the scientific method." They wrote: "Today, virtually all financial and experimental resources in cosmology are devoted to big bang studies. Funding comes from only a few sources, and all the peer-review committees that control them are dominated by supporters of the big bang. As a result, the dominance of the big bang within the field has become self-sustaining, irrespective of the scientific validity of the theory. "Giving support only to projects within the big bang framework undermines a fundamental element of the scientific methodthe constant testing of theory against observation. Such a restriction makes unbiased discussion and research impossible...." This image of a high-redshift quasar in front of an opaque low-redshift galaxy marks a crossroads in modern astronomy. If ideology prevails, astronomy as a science will die; if funding and journals are opened to empirical testing and questioning of assumptions, the big bang will die. For the time being, science must wait on the sidelines while the game of power politics plays itself out.

I thought that this would generate more interest than it has. Should have known: money beats intellectual curiosity ;)
There ought to be limits to freedom. - G.W. Bush, 21 May 1999
I love it when scientific dogma blows up in the academics faces. It's their religion and they are as rigid and orthodox as any fundamentalist. I've had many arguments with scientific fundamentalists particularly over evolution. My main objection to the their theories is not the theories themselves but the vehemence and rigidity with which they're promoted. If you deviate from whatever the currently held scientific religious belief is, you're tongue lashed with exceptional vitriol. I love it when it's proven that we don't yet know everything, and there are still unanswered questions.
"I woke up in the CRAZY HOUSE."
So much for the "big bang" theory. We have the same problem in physics, energy systems, global warming, and cancer treatment. The politicians/globalists decide the "answers." Science has nothing to do with it. It's all a matter of money and control.
all of 'em? ;)
As for WWIII, let's try something new. All I'm saying is give isolationism a chance.~~Pissed Off Janitor
Yep. ;0)

Tonight I was looking through my telescope, and saw a planet, with a lot of moons, most likely Jupiter. It was a really great bit of viewing. I love the stars. I wish I had the oppurtunity to go into space. Who knows, if NASA gets its shit together, I might get to, along with everyone else who wants to.
#7. To: rack42 (#0) I don't see why the big bang theory needs to die with this. The article concedes that BB critics do not understand why redshifting occurs. There may be something correct about current redshift interpretations, but which doesn't apply to quasars. I kinda think the BB is a really cool idea. Lot more exciting than a perpetual, static universe.
#8. To: rack42 (#0) I read an article a few weeks ago that said what most people think about the universe is not true. For example, it quoted the idea that our Sun is just one of of hundreds of billions in the known universe, so there should be life all over the universe. Apparently not true. Stars like ours only make up 5% of the known universe. Then, we have Jupiter, which is big enough and in the right place to sweep up a lot of meteors than come through, so they wouldn't hit the Earth. There were other things I have forgotton. The suggestion, though, is that life is very rare in the universe. What if we really are the only intelligent species? What does that mean?
"Benjamin Franklin was shown the new American constitution, and he said, 'I don't like it, but I will vote for it because we need something right now. But this constitution in time will fail, as all such efforts do. And it will fail because of the corruption of the people, in a general sense.' And that is what it has come to now, exactly as Franklin predicted." -- Gore Vidal #9.

TV dinners! I'm feelin' kinda rough; TV dinners! This one's kinda tough I like the enchiladas and the teriyaki too; I even like the chicken if.... the sauce is not too bleu. Top Page Up Full Thread Page Down Bottom/Latest |
