South Atlantic Ocean. 2103 GMT on a clear dark night. "The first thing noticed was the formation of a bright patch of white light in the general area between Rasalhague and Alphecca. Gradually a dark eye formed in the centre of the patch in which shortly afterwards a very bright object appeared like a star of magnitude -2 . After one or two seconds this object appeared to undergo a tremendous explosion and became a large bright orange gaseous fireball, which appeared to be hurled earthwards directly down the observer's line of sight, growing constantly larger and larger. One witness described the fireball as resembling rolling orange smoke. The ball then ceased to increase in size, giving the impression that it had stopped. Its orange colour rapidly gave way to rainbow colours which gradually gave way to white and faded in brilliance until all that remained were several patches of luminous white light, although these were impressive in their own right."

... Sourcebook Project Sourcebook Subjects The Big Bang As An Illusion That the universe began with the Big Bang is now so ingrained in our thinking that we almost never search for plausible alternatives. Perhaps the Big Bang is just a facade that diverts us from theories that better explain the observed characteristics of the universe. A trio of American and British astron omers (B .J . Carr, J.R . Bond, W.D . Arnett) are exploring the possibility that the cosmos began with a generation of very massive stars rather than the debris of the Big Bang. These huge stars would have had masses 100 or so times that of the sun. By virtue of the much higher pressures and temperatures at their cores, they would have burnt up their fuel inventories much faster than sun-sized stars. Thus they would have burnt themselves out long ago, probably surviving as black holes. Such an ancient generation of massive stars can explain four puzzling features of the universe: (1 ) The amount and character of the background microwave radiation. (2 ) The identity of the "missing mass" needed to hold the universe together (i .e ., the relict black holes). (3 ) The primordial abundance of helium. (4 ) The near-absence of heavy elements in the universe. Although the success of this hypothesis is far from total, it might help wean us away from the Big Bang.

Genuine Azilian pebbles seem to have been carefully selected for size and shape. Most are oval or oblong and may be up to 8 centimeters long, 3 centimeters wide, and one centimeter thick. Over a thousand have been found around Europe. They have been considered primitive art, markers for prehistoric games, and possibly early forms of notation. Claude Couraude has analyzed the markings and concluded that particular combinations of signs recur frequently; the same for certain numbers of dots. There are 16 simple types of signs (dots and lines) but only 41 of the many possible combinations have been found. Evidence supports the existence of some sort of 'syntax.' Couraud speculates that some sort of cyclic notation is involved, perhaps lunar in nature, like some of the markings found on bones from the same general period.

When examined in detail, these lobes turn out to be quite different in size, shape, and intensity. In particular, very bright regions on one lobe often correspond to gaps or regions of low brightness on the other. So striking are these asymmetries that astronomers think that these huge, tremendously energetic systems are ejecting material first from one side then the other. Somehow, one side of the galaxy or quasar communicates with the other, which may be many light years away, and coordinates a flip-flop action. How and why radio galaxies and quasars should flip-flop is a major mystery. (Anonymous; "Flip-Flop Radio Jets?" Sky and Telescope, 68:506, 1984.) Comment.

A preliminary analysis by Michael Mumma, of Goddard Space Flight Center in Maryland, and his colleagues. indicated that processes analogous to optical pumping in laboratory lasers were taking place and led to the coining of the term 'natural lasers.' Now, Deming and colleagues from the Goddard team have taken new observations of emission from Mars and Venus at wavelengths near 10 micrometers. and modelled them to show that stimulated emission -- the effect which makes lasers so powerful -- accounts for up to seven per cent of the total emission. This is not a large amplification factor by laboratory standards, particularly for a CO2 laser. But, the authors speculate that the sheer size of the natural lasers could make them useful tools in the future for communicating with distant civilizations beyond our own planetary system." The atmospheres of Mars and Venus are almost pure CO2 . The CO2 molecules are excited by the absorption of energetic solar photons; then, thermally emitted photons at about 10 micrometers from lower reaches of the atmosphere collide with the excited molecules, stimulating them to emit another 10-micrometer photon, thus doubling the number of photons. This is typical laser action. Deming and Mumma speculate that the natural laser action existing in the Martian atmosphere could be intensified and focussed into an intense beam of infrared radiation of enormous power by placing two large mirrors in orbit, creating a space-borne analog of a laboratory laser.

(3 ) Earth-moon accretion as a double planet . The compositions of the earth and moon are too different. This article concludes that the resolution of the problem of lunar origin must await our return to the moon for more scientific exploration. (Rubin, Alan E.; "Whence Came the Moon?" Sky and Telescope, 68:389, 1984.) An article in Science also discusses the classical theories of lunar origin and quickly disposes of them for the above reasons. However, a fourth theory makes an appearance, which we might call the Big Splash Theory. The idea is that a Mars-sized object (1 /10 the earth's mass) made a grazing collision with the earth when the solar system was more heavily populated with debris. This collision vaporized the projectile's rocky mantle as well as a similar quantity from the earth. This material was flung into orbit by the force of the impact and the expanding hot gases. Beyond the Roche Limit, the expelled debris coalesced into the moon. This fourth theory is now seriously considered by planetary scientists who -- so far -- have found no serious defects.

Two such cells abut the parasitic filament. The small black circles are parasitic cell nuclei which, when confronted with a red alga cell, become wrapped in small "conjuctor cells" which are then somehow transferred to the host cell on the right. The actual transfer involves the formation on the host cell wall of a sort of dimple called a "secondary pit connection." (Why this forms is not known.) Once inside the host cell, the parasite nucleus and/or the cytoplasm transferred with it dramatically reprograms host cell operations. The host cell shifts into highgear food production, enlarging up to twenty times its normal size. The host cell wall thickens, its nuclei (large black circles) and chloroplasts multiply.

The scaling up involved no high technology; in fact, even angular measurements were avoided. Instead of removing stones to make the lines, as the Nazcans did, lime was applied. The whole figure was laid out and limed in just a few man-hours. Then, from an aircraft at 1,000 feet, photos were taken. Lo and behold, a very convincing replica of the Nazca condor appeared on the prints. Still unanswered, though, is why anyone would want to make such huge drawings.

Although the ash gravitationally settles out within weeks, the aerosols spread around the globe and can remain suspended in the stratosphere for years. Because solar radiation is easily absorbed and backscattered by the volcanic particles, a haziness in the sky and a dimming of the Sun and Moon are produced. Very dense and widespread dry fogs occur, on the average, once every few centuries. The sizes and intensities of some of the largest of them before the modern scientific era have been estimated by several indirect methods. The densest and most persistent dry fog on record was observed in Europe and the Middle East during AD 536 and 537. Despite the earliness of the date, there is sufficient detailed information to estimate the optical depth and mass of this remarkable stratospheric dust cloud. The importance of this cloud resides in the fact that its mass and its climatic consequences appear to exceed those of any other volcanic cloud observed during the past three millenia.

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.

"It is concluded that on five occasions during the interval 20,000-14,000 years BP, cosmic dust mass concentrations in the solar system rose by one and two orders of magnitude above present day levels. Moreover if the particles found in these ice core samples are indicative of the particle size distribution which prevailed in the interplanetary medium at that time, then it may be concluded that the space number density of submicron sized particles must have uncreased by a factor of 105 or more. During these times the light transmission properties of the solar system would have been significantly altered resulting in major adverse effects to the earth's climate. Thus it is quite possible that these dust congestion episodes were responsible for the abrupt climatic variations which occurred toward the end of the last Ice Age."

The clear favorite among the four contending hypotheses was the earth-impact scenario, which may be stated as follows: "Near the end of the Earth's accretion, after its core had formed and while the growing planet was still molten, an object at least the size of Mars smashed into it at an oblique angle. The cataclysm put large quantities of vaporized or partially vaporized impactor and Earth into orbit. The primitive Moon formed from that material." Conferees turned thumbs down on the theory that the moon was captured by the earth. Still not ruled out are the double-planet hypothesis (earth and moon accreted in their present configuration) and the fission-from-earth theory. (Taylor, G.

From force of habit, he scanned the woods, his spotlight punching through black walls of rain. And there in the beam was one of the strangest creatures he had ever seen. About the size and shape of a dog, it was covered with stripes that ran from its shoulders across its back to its thick, rigid, tail. "The animal stood still as the startled ranger counted the stripes, then it nonchalantly gave an enormous jaw-stretching yawn. But when the ranger reached for his camera, the creature faded into the undergrowth, leaving nothing but a rank smell. It also left a trail of excitement, for the bizarre beast looked exactly like a Tasmanian tiger -- also called a thylacine or Tasmanian wolf -- an animal thought to have been extinct nearly 50 years ago." Hundreds of people claim they have spotted the Tasmanian tiger since the last captive died in 1936, but we have no good photos or other "proofs." Mediaman Ted Turner has offered a prize of $100,000 for "verifiable evidence" that the Tasmanian tiger still lives.

In fact, to a crystallographer, these crystals are the equivalent to ESP in psychology. All the rules of crystallography insist that icosahedral crystals should not exist. One scientist reacted in this way: "All my training has been with the assumption that crystals are periodic. Now, almost everything has to be reexamined."

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 the repulsion."

There he showed how quasars and so-called "superluminary" astronomical sources might emit light with a spectrum that evolves as it travels through space. Scientists have always assumed that once light left its source its spectrum remained unchanged. But Wolf shows how spectral changes are "sort of coded into the light due to correlations in the source." Meanwhile, two of Wolf's colleagues have backed up his theory in the lab. The consequences of Wolf's work would in effect shrink the universe, because objects would not be as far away as we now calculate from their redshifts. The size of the universe might contract "by a factor of 100 or more," says Wolf.

The Iowa group thinks that the holes or spots are created by meteors hitting the upper atmosphere because the spots follow the same time distribution as meteors. For example, they are more frequent during the well-known meteor showers. The theory is that the dark spots are formed when ice associated with the meteors is turned into water vapor, which reacts with the atmospheric oxygen producing the dayglow, in effect removing temporarily part of the light source. So far, everything seems relatively nonanomalous. But when quantities are calculated, though, jaws begin to drop. The sizes of the spots imply that the average meteor involved weighs 10 kilograms, mostly ice and far larger than has been thought. In fact, they may be characterized as small icy comets; that is, compositionally like the dirty snowballs that comets are now thought to be, but much, much smaller.

Biologists, including Darwin himself, have long puzzled over this. Stephen Jay Gould in a recent article explores a currently favored way of circumventing the negligible additional survival value of half a wing, or even 90% of a wing. This solution (? ) maintains that protowings were not "intended" for flight at all but were developed initially as aerodynamic stabilizers, thermoregulatory systems, sexual attractors or other functions requiring large areas. Gould describes the experiments of Kingsolver and Koehl in which protowings were modelled and tested for their thermoregulatory and flight values. Surprisingly, there was a sharp transition, as the size of the protowing increased, from good thermoregulation but poor flight capability to the reverse -- good flight capability and poor thermoregulation.

After hatching, the young cuckoos grow much faster than the young of the host species. Soon the cuckoo is able to eject the host's young from the nest and get all the food brought by the parents. Actually, the cuckoo is so aggressive in this business of parasitization that, when it finds a host nest with eggs so far along in incubation that parasitization is impractical, it destroys the whole nest. This usually forces the host birds to lay fresh eggs, giving the cuckoo a chance to parasitize the nest. The most remarkable thing about cuckoo parasitism is the birds' ability to match the eggs of the host species in size, spottedness, background color, and darkness. The eggs of all five species commonly parasitized in Britain are much smaller than a bird the size of the cuckoo would normally lay; but the cuckoo still manages to lay eggs of just the right size. When the bona fide eggs of the five parasitized species are placed side-by-side with the mimics layed by the cuckoos, the matches are uncanny - except in the case of the dunnock, which the cuckoo doesn't try to mimic at all.

Kyte et al have now provided additional details on meteoritic debris they first described in 1981. On the floor of the southeast Pacific, about 1400 kilometers west of Cape Horn, about 5 kilometers down, they found high concentrations of iridium in Upper Pliocene sediments about 2.3 million years old. Since the proposed projectile hit in very deep water, no crater was dug out. What did survive is called an "impact melt." This is debris rich in noble metals, such as iridium, and contains particles typical of a low-metal mesosiderite. Some 600 kilometers of the ocean floor received this debris. Kyte and his associates estimate the size of the impacting object at at least 0.5 kilometers in diameter. No biological extinctions are correlated with the 2.3 -million-year date, but there appears to have been a major deterioration of climate at about this time. There was a shift in the marine oxygen isotope records and, more obvious, the creation of the huge loess (sandy) deposits in China. What the impact may have done is to vaporize enough water into the atmosphere to increase the earth's albedo, reflecting sunlight back into space, lowering the average temperature, and thus triggering the Ice Ages.

For example, large nets have been destroyed and horses going down to the lake to drink have disappeared! (Anonymous; "Giant Fish Reported in China," ISC Newsletter, 5:7 , Autumn 1986.

Scientists have long known from laboratory experiments that various colors of light can affect stem size, root structure and other aspects of plant growth. But they have remained largely in the dark about the potential practical benefits of the phenomenon. "Using colored mulch to bathe plants in reflected light of certain hues, the South Carolina group (Clemson University) has begun to explore what colors plants prefer in agricultural growing conditions. Last year, for example, the group found that tomatoes grown with red mulch -- made with plastic sheets painted red -- had 20% higher yields than those with black mulch. Preliminary results this year show that potatoes and bell peppers grow best with white mulch...." (Anonymous; "Plants' Colors," Wall Street Journal, September 16, 1987. Cr. J. Covey.) Comment. Many questions arise here, but we'll take only three: (1 ) How do plants sense colors? (2 ) How do different colors mediate growth differently? (3 ) Is all this explicable in terms of evolution?

" ! ?Photographs of Comet Bradfield taken on October 10, 1987, show an odd kink in its tail that does not appear on photos taken the nights before and after. This kink was shaped like a backwards "? ". Kinks in the tails of comets are well known phenomena. A comet's tail is electrically charged, and it flaps in the solar wind like a flag on a gusty day. So why run this observation up the anomaly flagpole? First of all, the Bradfield kink is 10 million kilometers long; second, it appeared and disappeared in a matter of hours. Both size and speed-of-formation are difficult to explain in terms of existing solar-wind velocity and the shifting interplanetary magnetic field. (Anonymous; "Did Anyone Photograph This Comet?"

A good-sized chunk of earth or "divot" had been neatly excised intact from the ground and deposited some 73 feet away. (see drawing.) One would think that nature would play only one such bizarre prank, but a remarkably similar occurrence also took place in 1887. A third example of this most curious phenomenon has been resurrected from one of the Middle Ages chronicles: "822 A.D .: 'In the land of the Thuringians, near a river, a block of earth 50 ft. long, 14 ft. wide, and 1 ft. thick, was cut out, mysteriously lifted, and shifted 25 ft. from its original location.' Royal Frankish Annals." (Carolingian Chronicles. W. Scholz, translator, Ann Arbor, 1972. Cr. E. Murphy) Reference.

... (From: Encyclopedia Americana) Just before the turn of the century, two leaders of the Theosophical movement, Annie Besant and C.W . Leadbeater, decided to collaborate on Goal 3 and investigate the micro-structure of matter. They eschewed the physics laboratory, preferring instead ESP. S. Phillips has now summarized their discoveries in a compact little paper. He concludes as follows: "This article has presented a few examples of the many correlations between modern physics and psychic descriptions of sub-atomic particles published over seventy years ago. Scientists and laypersons alike may find it difficult to believe that Besant and Leadbeater could in some way unknown to science describe the structure of objects at least as small as atomic nuclei, which are about one ten-thousand-billionth of an inch in size. But they cannot in all sincerity dismiss the Theosophists' claims as fraudulent for the obvious reason that they finished their investigations many years before pertinent scientific knowledge and ideas about the structure of sub-atomic particles and the composition of atomic nuclei became available to make fraud possible in principle. "Nor can critics plausibly reject their claim to possess micro-psi powers at its face value and interpret, alternatively, their observations as precognitive visions of future ideas and discoveries of physics. If they had been merely looking into the future, they might reasonably, have been expected to describe atoms or atomic nuclei or both, not more exotic objects formed from two nuclei. The Rutherford-Bohr model of the atom was formulated after they had finished most of their work on MPAs. Yet none of ...

Science Frontiers ONLINE No. 64: Jul-Aug 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Libyan Desert Glass Pieces of Libyan Desert Glass weighing as much as 16 pounds are found in an oval area measuring approximately 130 by 53 kilometers. The clear-to-yellowish-green pieces are concentrated in sand-free corridors between north-south dune ridges. The origin of this immense deposit of glass has been attributed by some to ancient nuclear explosions and alien activities, but investigating scientists have always been satisfied with a meteor-impact hypothesis. A recent study (abstract below) also opts for this explanation, although no one has found a crater of suitable size or other supporting evidence. "Libyan Desert Glass (LDG) represents 1.4 x 109 g of natural glass fragments scattered over about 6500 km2 of the western Desert of Egypt. We made a systematic study (employing INAA, microprobe and mass spectrometry techniques) of several varieties of LDG and locally associated sand and sandstone to provide insight into the nature and formation of these enigmatic glass fragments. These studies indicate that: Although the LDG has restricted major element compositions (97.98 wt% SiO2 ; 1-2 wt % Al2 O3 ) their trace element contents (ppm) (Fe, 490-5200; Co, 0.2 -1 .2 ; Cr, 1.2 -29 and Sc. 0.462.5 ) vary by as much as a factor of 5 to 30. The LDG fragments exhibit a factor of ...

... No. 59: Sep-Oct 1988 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Nereid: grotesque shape or two-faced?Nereid, a satellite of Neptune, is peculiar in several ways: Its orbit is retrograde and highly elliptical (1 .4 x 9.7 million kilometers) Its brightness changes by a factor of four as it rotates Its diameter, according to M.W . and B.E . Schaefer (Nature, 333:436, 1988) is thought to be at least 660 kilometers. None of these facts taken alone is anomalous, but (2 ) and (3 ) taken together seem incompatible. If the large brightness changes are due to a highly irregular shape, Nereid's 660-kilometer size is too large, because astronomers agree that gravitational forces will sphericize all objects larger than 400 kilometers. On the other hand, if Nereid is two-faced, like Saturn's moon Iapetus (it's carbon-black on one side, light-colored on the other), astronomers are again faced with trying to explain how such a large solar-system object can acquire so much carbonaceous material on one side only. Also, Nereid's eccentric, retrograde orbit surely hints at a history of capture or orbit disruption. (Weisburd, S.; "Neptune's Nereid: Another Mysterious Moon," Science News, 133:374, 1988.
