Scientists have postulated that these comets, which orbit relatively close to the sun, originally came from the far-distant Oort Cloud on parabolic (non-returning) orbits around the sun. Perturbations by the planets, notably Jupiter, deflected them into the tighter orbits we see today. The problem is that the number of parabolic comets entering the inner solar system from the Oort Cloud of comets (located at the outermost fringes of the solar system) is 100 times too small to account for the existing population of short-period comets. M.E . Bailey believes this discrepancy can be removed if the Oort Cloud possesses a massive inner core of comets. (Bailey, M.E .; "The Near-Parabolic Flux and the Origin of Short-Period Comets," Nature, 324:350, 1986.) Reference. The Oort Cloud of comets is an entrenched part of astronomical dogma.

With these caveats, they reproduce an Indian tradition originally set down by Judge James Swan back in 1888: "' A long time ago,' said my informant, 'but not at a very remote period, the water of the Pacific flowed through what is now the swamp and prairie between Waatch village and Neeah Bay, making an island of Cape Flattery. The water suddenly receded leaving Neeah Bay perfectly dry. It was four days reaching the lowest ebb, and then rose again without any waves or breakers, till it had submerged the Cape, and in fact the whole country, excepting the tops of the mountains at Clyoquot. The water on its rise became very warm, and as it came up to the houses, those who had canoes put their effects into them, and floated off with the current, which set very strongly to the north.'" The authors of the present article wonder if the above could be an account of a massive tsunami!

As usual with such remarkable ancient structures, the overzealous have proposed antigravity devices, stone-softening agents, and similar wild notions. In truth, as J.

Protzen has spent many months in Inca country experimenting with different methods of shaping and fitting the same kinds of stones used by the Incas. He found that quarrying and dressing the stones were not problems at all using the stone hammers found in abundance in the area. Even the precision-fitting of stones was a relatively simple matter. The concave depressions into which new stones were fit were pounded out by trial and error until a snug fit was achieved. Protzen's first-hand experience is impressive and convincing. Certainly he required no radical solutions. The problems that Protzen was not able to solve to his satisfaction involved the transportation and handling of the large stones.

As they observed the Space Shuttle streak across the sky, "they both heartd an unmistakable 'swishing noise' as it passed south of their rural Galveston County home. The sonic boom came several minutes later -- but the swishing sound occurred simultaneously with the visual apparition....Ben graphically described the sounds as 'like a skier coming down a slope,' but with a rapid fluctuation in loudness, 'about two or three hertz.' Jeannette compared the faint sound to the noise made by a fast boat as it slaps across waves on a choppy lake. 'But there was no motor noise,' she added, 'just a sound like repeated puffs of air through your mouth.'" Oberg points out that the mysterious Space Shuttle sounds are basically the same as the anomalous swishes and whizzes attributed by some to meteors.

Tifft and Cocke begin their article with this sentence. Wisely, they followed with the tale of how vehemently the quantization of the atom was resisted earlier in this century. They were wise because without such a reminder to be open-minded, many astronomers would automatically toss their article in the wastebasket! In fact, when Tifft's first paper on redshift quantization appeared in the Astrophysical Journal, the Editor felt constrained to add a note to the effect that the referees: "Neither could find obvious errors with the analysis nor felt that they could enthusiastically endorse publication." Even today, after much more evidence for redshift quantization has accumulated, scientific resistance to the idea is extreme. We shall now see what all this fuss is about. Tifft first became suspicious that the redshifts of galaxies might be quantized; that is, take on discrete values; when he found that galaxies in the same clusters possessed redshifts that were related to the shapes of the galaxies. The obvious inference was that the redshifts were at least partly dependent upon the galaxy itself rather than entirely upon the galaxy's speed of recession (or distance) from the earth. Then, he found more suggestions of quantization. The redshifts of pairs of galaxies differed by quantized amounts (see figure). More evidence exists for galactic quantization, but ...

The focus of a 1987 paper in Scientific American, by C.H . Nelson and K.R .

The pits range from 1-10 meters in length, 0.5 -7 meters in width, and 0.1 -0 .4 meters in depth. No known geological processes seem responsible. Farther east, in Nor-ton Sound, methane eruptions from buried organic matter do blow out circular craters; but the elongated pits investigated by Nelson and Johnson are gouged in sand considered too permeable for gas-crater formation. Rather surprisingly, the gray whale has become suspect as a pit excavator. They feed in the area of the pits; and the pits, before enlargement by currents, are just the size of the whales' mouths. The whales apparently dredge up sediment and, with their baleen, strain out amphipods (shrimp-like crustaceans) from the sand. The coexisting narrow furrows turn out to be the work of walruses digging for clams. (Nelson, C.

Leave comfortable earth for a moment and consider the immense, cold clouds of gas and dust swirling between the stars and galaxies. At near-absolute-zero, sunless and waterless, these clouds hardly seem the womb of life. Yet, there may be found the atoms necessary to life -- H, C, O, N, etc -- and in profusion. Collisions of cosmic rays can promote the synthesis of fairly large molecules. We have already detected molecules as complex as formaldehyde in the interstellar medium. But surely the immensely more complicated molecules of biology cannot be synthesized near absolute zero. This may not be true either because at extremely low temperatures the quantum mechanical phenomenon of "tunnelling" becomes important. To achieve molecular synthesis, repulsive barriers must be overcome. The warm temperatures in that terrestrial pond can provide the extra kinetic energy to climb over these barriers. In cold molecular clouds we must look elsewhere. The laws of quantum mechanics state that there is always a very low probability that atoms and molecules can tunnel through repulsive barriers -- no need to climb over them via thermal effects. "Specifically, entire atoms can tunnel through barriers represented by the repulsive forces of other atoms and form complex molecules even though the atoms do not have the energy required by classical chemistry to overcome ...

Now, in a strange turn-about, a creationist writer is using evolutionary theory to infer a very short history for the formation where geologists want a good deal of time. We quote from the conclusion of J.R . Meyer: "If any group of animals were ever going to undergo significant degrees of evolution from parent stock and obtain resultant speciation, surely the Kaibab squirrel would be one of the more likely candidates. Supposedly isolated from their neighbors for hundreds of thousands of generations over a period of at least several million years, and significantly violating virtually every restriction of the Hardy-Weinberg equilibrium for the non-evolving population, these organisms, even by creationist standards, should have undergone significant and detectable changes. In reality all they show are moderate changes, primarily in two coat color characteristics for part of their population. To make things even worse, this species is known to have a highly variable coat-color polymorphism throughout its range. Thus, even the differences displayed appear to be easily accounted for by several mutations and a slight change in gene frequency for one or two loci, all occurring in a limited period of ...

Stanley, one of the proponents of punctuated evolution. Either fate or the mysterious forces of seriality seemed to be saying that it is now time to broach the subject of the quantization of life itself. The reader can blame Stanley only for the stimulus and his discussions of speciation and the discontinuous (quantized?) fossil record. (Campbell, Neil A.; "Resetting the Evolutionary Timetable," BioScience, 36:722, 1986.) Comments. When we suggest quantization in biology, two phenomena come to the fore: 1. The obvious splitting of life into well-defined states -- the species -- as defined morphologically and/or by the genetic code; and 2. The gaps in the fossil record, which imply a frequent lack of transitional forms from one species to another. As Stanley asserts repeatedly in his interview, the fossil record is actually quite good in many places, despite the long-voiced claims of the gradualists that transitional forms do not exist merely because of the deplorable state of the fossil record. In physics the analogous phenomena would be: (1 ) The chemical elements and their isotopes (or an atom's energy levels); and (2 ) The lack of transitional forms. Straining the analogy still further, the evolution ...

As with most of the plumes, movement of the vapor does not correspond to wind direction. Volcanic activity and natural methane gas releases are considered unlikely explanations.

If further surveys confirm a bubbly universe, the "conventional explanations for the evolution of large-scale structure in which gravity played a dominant role may have to be modified or abandoned." To explain the bubbles, a new scenario has Big Bang #1 creating a population of uniformly distributed, extremely massive stars, which eventually burned out and exploded in a crescendo of supernovas.
