Quasars with this distribution of apparent magnitude and redshift have a negligible chance of being drawn from the population of quasars present in other areas of the sky. At a mean redshift distance corresponding to their average z = 2, these quasars would represent an unprecedented inhomogeneity over enormous volumes of space in the universe." It is difficult for astronomers to accept such a large "bubble" in the cosmos, because the Big Bang Theory basically produces a "smooth" universe. The author of this paper, H. Arp, comments that the size of the inhomogeneity could be shrunk considerably if redshifts were not taken as measures of distance.

In addition to the hypothesized solid inner core, the fluid outer core, and the encapsulating solid mantle, there seems to be continentsized inhomogeneities in the vicinity of the mantle and the outer core. The anomalous seismic signals can be interpreted as huge blocks of different composition and/or temperature. T.H . Jordan, from MIT, ventures: ". .. that what they have mapped are 'continents' on the core-mantle boundary. 'What we've seen is something really incredible,' he says. According to Jordan, the anomalies are analogous to continents on the surface of the earth, because they can't be accounted for by temperature variations but must reflect some compositional change as well. These features 'represent the scum or slag that sits up on the outer core boundary, just as continents sit on the outer surface of the earth,' he says." Some have even speculated that these subterranean chunks of debris are pieces of surface continents that were subducted at the plate boundaries long ago. There are, after all, missing pieces in the continental drift jigsaw puzzle. There might even be substantial chunks of asteroids and comets down there waiting, like the Titanic, to be explored by scientific instruments. Can once-subducted continents and ...

Science Frontiers ONLINE No. 9: Winter 1979 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Large, unseen mass is pulling earth toward it Recent measurements of the cosmic microwave background indicate that the earth moves relative to it. New cosmic X-ray data from the satellite Ariel 5 suggests that a large, hitherto unsuspected mass is located in the same direction that the earth is moving. Thus, both X-ray and microwave data could be explained by supposing this mass to be large enough to pull the earth (and our Galaxy) toward it. This mass would have to be about 10 billion light years away and weigh as much as 100 million Galaxies. Such a gigantic blob or inhomogeneity in the universe would be very difficult to explain. As it is, the aggregation of stars into galaxies after the Big Bang remains poorly understood. The bigger the inhomogeneity, the harder it is to account for. The Big Bang should have spread matter out pretty evenly. (Anonymous; "Large Mass May Pull Earth Through Space," New Scientist, 83:21, 1979.)

Two researchers now say the universe is even lumpier, has faster relative motion and shows larger structures than previously believed." N. Bahcall and R. Soneira have been studying the structures and motions of superclusters of galaxies. Each supercluster consists of clusters of clusters of galaxies and contains upwards of hundreds of billions of stars. (Obvious-ly, these are not inconsequential entities!) By analyzing the redshifts of galaxies, Bahcall and Soneira have found that the universe is much more dynamic and inhomogeneous than expected. (1 ) The clusters of galaxies are larger and more extensive. Superclusters can be 500 million light years across -- about 1% of the known universe (2 ) Relative motions within the clusters are as high as 2,000 kilometers per second more than one can account for using gravitational attraction alone. (Kleist; T.; "Lumps, Clumps and Jumps in the Universe," Science News, 130:7 , 1986.) Comment. Before swallowing whole such grand sketches of the cosmos, one should always examine the assumptions. Here, redshifts are assumed to be measures of velocity, which if an expanding universe is assumed, can be converted into distances. Local Group of galaxies, including the Milky Way. and nearby superclusters are all moving ...

... now, astronomers have been haunted by a sense that the universe is controlled by forces they don't understand. And now comes a striking confirmation: 'The Great Wall.'" The Great Wall is the largest known structure in the universe at present, having superceded sundry superclusters and clusters of superclusters. The Wall is a "thin" (15 million-light-year) sheet of galaxies 500 million light years long by 200 wide; and it may extend even farther. It is emplaced some 200-300 million light years from earth. It helps outline contiguaous parts of vast "bubbles" of nearly empty space. Both the Wall and the adjacent voids are just too large for current theories to deal with. All popular theories have great difficulties in accounting for such large inhomogeneities. To illustrate an important observable -- the 2.7 K cosmic background radiation -- which is usually described as the afterglow of the Big Bang, ar gues for a very smooth, uniform distribution of galaxies. Great Walls are definitely anomalous. M.J . Geller, codiscoverer of the Great Wall with J.P . Huchra, remarked: "My view is that there is something fundamentally wrong in our approach to understanding such large-scale structure -- some key piece of the puzzle that we're missing." (Waldrop, M. Mitchell; "Astronomers Go Up against the Great Wall," Science, 246:885, 1989.) Also: Geller, Margaret J., and Huchra, John P.; "Mapping the Universe, ...

... Science Frontiers ONLINE No. 47: Sep-Oct 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Clump Of Antimatter The clumpiness of the universe described above assumed ordinary matter. Perhaps there are inhomogeneities on a different, more basic level -- matter vs. antimatter. According to one popular theory, the universe began with equal amounts of matter and antimatter. If so, where did all the antimatter go? We assume we observe a universe that is virtually 100% matter. Of course, we cannot really tell for certain because an antimatter galaxy would appear to us just like a galaxy composed of ordinary matter. The only clues revealing substantial pockets of antimatter would be the annihilation radiation produced where matter and antimatter regions rubbed against one another. The two types of matter always annihilate one another in bursts of very distinctive radiation. Well, there seems to be at least one region of antimatter near the center of our galaxy. The HEOS3 satellite and ballon-borne instruments have pinpointed a source of 511 kev gamma rays that can come only from a spot where electrons and positrons are mutually annihilating each other. (The positrons are antimat-ter analogs of electrons.) This region of mutual destruction is about 1013 kilometers across. Is it a pocket of antimatter left over after the Big Bang that a sea of surrounding matter is finally wiping out, or is it newly created antimatter in the vicinity of a black hole? No one knows. The mystery has deepened with the discovery that the intensity of the annihilation radiation varies with ...

... the greatest scientific advance of the century, completely ignoring the genetic code, continental drift, nuclear fission, and so on and so on. More sober scientists rejected such extravagant claims. They pointed out that independent confirmation of the fluctuations was yet to come and that, after all, the fluctuations were very small (only some 30 millionths of a K). And which of the many variations of Big Bang was going to be enthroned? Even Nature advised extreme caution, quoting H. Bondi in this regard: ". .. the data in cosmology are so likely to be wrong that I propose to ignore them." (Anonymous; "Big Bang Brouhaha," Nature, 356:731, 1992.) Comment. It is ironical that before astronomers found large-scale inhomogeneities in the cosmos (galactic clusters and superclusters, the Great Wall, etc.), the Big Bangers claimed that the very smoothness of the microwave background proved the reality of the Big Bang. The Big Bang, it seems, is one of those "politically correct" paradigms, which one criticizes at his peril. (Beichman, Arnold; "The Big Bang Censorship," Insight , p. 22, April 13, 1992. Cr. B.
