... Here are ruins of the greatest temple the Romans ever tried to construct. However, we must focus not on mundane Roman temples but upon a great assemblage of precisely cut and fitted stones, called the Temple today, which the Romans found ready-made for them when they arrived at Baalbek. It was upon this Temple, or stone foundation, that the Romans reared their Temple of Jupiter. No one knows the purpose of the much older Temple underneath the Roman work. J. Theisen has reviewed the basic facts known about the Temple's construction -- and they are impressive, perhaps even anomalous. Being 2,500 feet long on each side, the Temple is one of the largest stone structures in the world. Some 26 feet above the structure's base are found three of the largest stones ever employed by man. Each of these stones measures 10 feet thick, 13 feet high, and is over 60 feet long. Knowing the density of limestone permits weight estimates of over 1.2 million pounds. Some people with impressive engineering skills cut, dressed, and moved these immense stone blocks from a quarry 3/4 of a mile away. A walk to this quarry introduces the observer to the Monolith, an even larger block of limestone: 13 feet, 5 inches; 15 feet, 6 inches; and 69 feet, 11 inches. The Monolith weighs in at over 2,000,000 pounds. In comparison, the largest stones used in the Great Pyramid tip the scales at only 400,000 pounds. Not until NASA moved the ...

... rock that is hard and durable. In nature it sometimes occurs in long prisms of hexagonal cross section. In fact, ancient Micronesians quarried multiton basalt prisms to build their fantastic megalithic complex of 92 artificial islets at Nan Madol. (SF#45) The inhabitants of ancient Mesopotamia had no basalt quarries at hand. Indeed, building stone of any kind was exceedingly scarce. What the Mesopotamians of the second century B.C . did have in abundance was alluvial silt. From this unpromising material they were able to make their pottery, writing tablets, and art objects. However, for grinding grain and engineering structures they needed something harder and stronger. Their innovative solution was: artificial basalt made from silt. They simply melted the silt and let it cool slowly. Sounds simple, but three remarkable intellectual and technical advances were required: The Mesopotamians first had to recognize that silt could be melted. This could not have been obvious in 1000 BC. Next, they had to develop hightemperature (1 ,200 C) smelters that were much larger than those they used for metallurgical purposes. Finally, they had to discover that slow cooling was needed for the growth of large crystals in the cooling melt. (Of course, they had no microscopes to see the crystals. So, it had to have been something learned from experience.) That the Mesopotamians were able to synthesize basalt can be seen at Mashkanshapir about 80 kilometers south of Baghdad. Slabs of this artificial rock -- flat and smooth on one side from the molds -- are abundant. In fact, some ...

Does this mean that the Big Bang, the mainstay of the astronomy we were taught in school, is now being cast aside? After all, the Big Bang does model fairly well three important observations: The apparent expansion of the universe; The 3 K microwave background; and The abundances of the light nuclei. But try as they may, cosmologists have not been able to coax the Big Bang model to explain the large-scale lumpiness and structure of the galaxies and galaxy clusters. One problem with the Big Bang is that it has too many free parameters -- too much theoretical slack. Many cosmologists are now looking for a better model. This better model, to use the words of P. Coles, should be more "exciting" and "stranger," something "perhaps not even based on General Relativity." (Coles, Peter; "The End of the Old Model Universe," Nature, 393:741, 1998.) Questions.

... ancient oil -- and abundant life Geologists usually don't bother looking for oil in very ancient (Precambrian) rocks for two reasons: Conventional wisdom insists that oil is derived almost exclusively from organic matter, and additional conventional wisdom assures us that life was exceedingly scarce on earth billions of years ago. Any oil that was created billions of years ago would have surely been destroyed by intense pressures and high temperatures over the eons. Yet, Precambrian oil in commercial quantities has been found in formations up to 2 billion years old (in Siberia, Australia, Michigan, for example). While some of this oil might have migrated in-to the Precambrian rocks from younger source rocks, some of it does seem indigenous and, therefore, ancient. (SF#48) Now, three Australian scientists (R . Buick, B. Rasmussen, B. Krapez) have discovered tiny nodules of bitumen (lumps of hydrocarbons) in sedimentary rocks up to 3.5 billion years old in Africa and Australia. These bitumen nodules were formed when natural hydrocarbons were irradiated by radioactive isotopes that coexisted in the ancient rocks. Futhermore, these African and Australian rock formations were never severely deformed or subjected to high temperatures. The possibility exists, therefore, that some of the earth's oldest rocks may contain substantial oil reserves. So far, no one has seriously looked for oil in Precambrian rocks because of the two preconceptions noted above. (Palmer, Douglas; "Any Old Oil?" New Scientist, p.22, March 14, 1998.) Comments.

As is often the case, this display began with parallel phosphorescent bands (2 sets) rushing toward the ship at about 40 mph. They were 50-100 cm above the sea surface. The bands then changed into two rotating wheels; then a third wheel formed. All three rotated counterclockwise, with their hubs 300, 300, and 150 meters from the ship. The spokes stretched to the horizon. The display ceased for about 20 minutes and recommenced with four systems of onrushing parallel bands, which soon metamorphosed into four rotating wheels. Radar, visible light (from an Aldis lamp), and engine revolution appeared to have no effect on the spectacle. Next, evenly distributed, circular, flashing patches of brilliant blue-white light appeared all around the ship out to a distance of about 150 meters.

Here the rulers of Cush built some 228 pyramids, three times as many as the Pharaohs managed to pile up! We rarely hear or see anything of these strange, steeply pointed structures. They are usually less than 100 feet high and not as impressive and mysterious as those farther north beyond the Aswan Dam. The Sudanese pyramids are smaller, steeper, and more recent than those to the north in Egypt. The Cushite kingdom's passion for pyramids was probably acquired in the Eighth Century B.C ., when it actually ruled Egypt for a few years until the Assyrians pushed its armies back south in 671 B.C . With them, the Cushites took the pyramid idea, Egyptian art forms, and hieroglyphics. They liked pyramids so well that the Cushite rulers kept on building them until the kingdom's demise in 350 A.D . -- some 2,000 years after the Egyptians had abandoned this form of architecture altogether.

Old Kingdom craftsmen laboriously cut this hard, black, glassy rock into royal sarcophagi and pavements for the mortuary temples at Giza just outside Cairo. To transport the heavy blocks of basalt from the quarry to Giza, the Egyptians built a quay on Lake Moeris, which then had an elevation of 66 feet above sea level and was located 7 ½ miles southeast of the quarry. (The Lake is now much smaller and 148 feet below sea level, indicating a large climate change.) Then, when the Nile flooded and its waters reached a gap in the hills separating the Lake and the Nile, the Egyptians were able to float the blocks of basalt over to the Nile and down to Cairo. Good thinking! But how did they transport the heavy blocks 7 ½ miles from quarry to quay? The answer: What was apparently the first paved road on the planet. This 4,600-year-old engineering feat averaged 6 ½ feet wide and was paved with thousands of slabs of sandstone and limestone, with some logs of petrified wood thrown in. Since the slabs show no grooves, it is thought that the stone-laden sleds moved on rollers.

Also, as it often happens, closing one book opens another and the new one is even harder to close. Below, we present three examples where finality (closed books) seems to be proclaimed too quickly.

Additionally, it is easy to doubt the existence of the ashen light because good explanations are as elusive as the light itself. During the past decade, two scientific nails have also been driven into the ashen-light coffin: Spectrographic studies of the upper atmosphere of Venus do detect some nighttime air glow, but it is much too weak to account for the abundant telescopic observations from earth.

Demonstrating the veracity of this statement are the following three quotations. Increasingly, a picture of interactivity and multifunctionality among genes is emerging that precludes such a simple one-to-one mapping. Furthermore, the genome can exhibit considerable flexibility to adapt when the expression of a particular gene fails, and the interpretation of a mutant phenotype [life form] is also less trivial than it may seen. "Not only are behavioural phenotypes very sensitive to non-genetic influences," writes [R .] Greenspan, "but also the highly interconnected network of the nervous system sets up an additional layer of complexity between the gene and the realization of the phenotype." (Ref. 1) Many genes code for multiple variants of the same protein. And many proteins are modified by adding sugar molecules, which play a big role in determining where proteins go and what they do. What's more, different proteins can join together to carry out completely new functions. (Ref. 2) A group of French biologists, led by Francois Jacob and Jacques Monod showed that the gene's boundaries are fuzzier than had been thought and that genes are not restricted to chromosomes.

A sharp arrow for their qui ver has just appeared in Science. Caterpillar-ant vibrational communication. Some species of caterpillars cannot survive predation unless they are protected by ants. To attract the ants, who just happen to dote on special secretions of the caterpillars, the caterpillars send out vibrational signals across leaves and twigs. In addition to their secretory structures, the caterpillars have also evolved novel vibrators to send out their calls for protection. A few butterfly species from all continents (except Antarctica) have evolved these devices. Looking at this geographical spread, P. J.

Planetary exploration by deep space probes in recent years has shown that the dipole moment of some mag netized planets has a surprisingly large inclination angle with respect to the rotation axis. It is argued that the inclined dipole thus obtained may not be physically realistic. Applying the method we have developed for the source surface magnetic field of the sun (a spherical surface of 2.5 solar radii), it is suggested that the main dipole of the earth and the magnetized planets is actually axial (the magnetic moment is parallel or antiparallel to the rotation axis), and that two or three smaller dipoles near the core surface are responsible for the apparent inclination of the main dipole."

Eruptions of Old Faithful Geyser are generally perceived as extremely regular events, with variation of eruptive interval being attributed to random noise. The governing equations for such a hydrothermal system are highly non-linear, therefore it is reasonable to assume that such systems are capable of operating in regines that display chaotic behavior. Three-dimensional state-space reconstruction of eruption time data provides strong evidence of a strange attractor quite similar to the Rossler attractor. Establishing the system as chaotic indicates that while one can predict eruptive intervals in the short term, long term predictions regarding Old Faithful's eruptive behavior are impossible, no matter how carefully and accurately the system is modeled. The mean eruptive interval of Old Faithful has changed over time. This is consistent with the behavior of a chaotic system, which by definition must be nonstationary in the mean. Seismic activity is believed to be a perturbation shifting Old Faithful into a new chaotic state with a different shape to the strange attractor. A simple non-linear dynamic model of geyser behavior is proposed that leads to chaotic behavior and is consistent with the observations of eruption interval data for Old Faithful."

It was described as a brilliant, yellow green, transparent ball with a fuzzy outline which descended from the base of a towering cumulus over Garn Fawr Mountains and appeared to 'float' down the hillside. Intense light was emitted for about three seconds before flickering out. Severe static was heard on the radio. The object slowly rotated around a horizontal axis, and seemed to 'bounce' off projections on the ground. It was noticed that cattle and seabirds in the immediate vicinity became disturbed."

What also seems likely, according to K. Strier, of the University of Wisconsin, Madison, is that some monkeys regulate their fertility by the judicious consumption of certain plants. Going even farther, K. Glander, Duke University, suggests that howler monkeys control the sex of their offspring through their diets. Glander divides howler monkey females into three groups. In the first are the high-ranking females that predominantly produce male offspring. This 'male-offspring' strategy favors these females because the males they produce tend to become dominant adults that will pass on more of the females' genes than would female offspring, who are limited in the number of infants they can engender in comparison to the males. Similar optimization strategies, according to Glander, induce middleranking females to produce mainly female progeny, and low-ranking females to birth almost all males. These howler monkeys seem to control the sex of their offspring pharmologically by selecting certain plants to eat. These plants, in turn, control the electrical conditions in the females' reproductive tracts to either attract or repel sperm carrying the male Y-chromosomes, which are thought to carry different electrical charges than the X-carrying sperm!

Finally, they chemically force the ants into defensive postures against predatory wasps by spraying them with a mesmerizing substance from special "tentacle organs" near their heads. Why is all this subversive on the part of the caterpillars? It appears that the caterpillars have invaded and undermined the normal ant-plant symbiosis -- a very common, mutually beneficial arrangement. The ants have been seduced into letting the caterpillars feast on the Croton plant, although the ant-plant compact originally required that the ants repel all herbivorous insects.

Unquestionably the brain does rely in part upon the transmission of electrical signals for some of its operations, but it now appears that there is a complementary mode of communication that relies upon chemistry rather than electricity. While the fastest way to transmit signals in the brain seems to be along the neurons and across their points of contact, the synapses, other signals may travel -- a bit more slowly -- by what is termed "volume transmission." Volume transmission is like broadcasting radio waves in three dimensions, except that in the brain the radio waves are replaced by the diffusion of chemical signals. L.F .

Stellar aberration, discovered nearly three centuries ago by Bradley, was immediately recognized as a phenomenon owing to the velocity of the earth in its orbit around the sun. Einstein provided an explanation of aberration in his famous 1905 paper using his new relativity theory, and his explanation remains essentially without modification in many modern textbooks. Herein, we show that his explanation is very much in disagreement with measurement. (Hayden, Howard C.; paper to be published in Galilean Electrodynamics , vol. 4, no. 5, 1993.) A Comment. The essence of Prof. Hayden's main argument is that, if stellar aberration depended on the relative velocity between source and observer (as Einstein maintained), then each component of a spectroscopic binary star would have drastically different stellar aberration, contrary to observation.

The "real" subterranean world turned out to be quite different from that inferred from both surface indications and the seismic and electrical probing of the depths. Three specific surprises are worth mentioning: Temperatures in the drill hole rose far faster than predicted. The expected boundary (" suture") between two old tectonic plates thought to exist at 3 km according to surface geology had not yet appeared at 7.5 km. Most interestingly, crevicular structure (crevices and pores) existed at almost all depths, even though theory said they could not because of intense pressures. And these voids were filled with fluids. P. Keher, a KTB scientist, was amazed at what the drill found: "When I started 25 years ago, the idea was that the deeper you go into the crust, the drier it gets."

... from kimberlite pipes. Diamonds are never pure carbon; they always contain some nitrogen and boron. Occasionally, they harbor tiny radioactive impurities; usually alpha-particle emitters in the uranium-238 decay chain. Alphas emitted by these impurities have well-defined energies and penetrate the diamond matrix only so far. If one examines a diamond with a high-power microscope (say, at 100 x), one can see concentric rings surrounding the impurities. These dark radiohalos or "pleochroic" halos have specific radii and can be used to identify the radioisotopes that produced them. So far, so good; but: "The fact that fully formed, optically visible internal radiohalos in diamonds are now presented casts a considerable shadow over current theories of diamond genesis." Actually, the radiohalos pose three challenges to diamond-genesis theory. Problem 1. The half-lives of the halo-creating radioisotopes are measured in thousands of years rather than the billions prescribed for crystallization. In fact some of the half-lives are only minutes or days long. M.H . Armitage comments: "How could these halos become imprinted if the formative cooling processes involved require such lengthy intervals?" Problem 2. The radioactive impurities producing the radiohalos are very tiny -- about 2-4 micrometers in diameter -- and are highly concentrated. Armitage continues: "What is most difficult to understand is that many of these inclusions and impurities have much lower melting and boiling points than the diamonds in which they are found." Why did the impurities fail to disperse as the higher- ...

... 000-BP barrier across the Bering Strait, establishment archeologists have erected another barrier which researchers cross at their peril. This time, the line is drawn at L'Anse aux Meadows, in Newfoundland, where a Viking presence has been officially acknowledged. Any Viking innuendoes south of this point in North America are verboten. The Spirit Pond Inscription Stone, 10-line side. Nevertheless, tantalizing Viking traces are found along the New England coast and, even more anomalously, in interior North America. One of these traces is the famous and infamous Spirit Pond Insciption Stone, found in Maine. It is covered with Norse runes. This inscribed stone was found by W. Elliott in May 1971, while he was paddling around Spirit Pond in a little rubber boat. Actually, Elliott discovered three stones with markings, but here we attend only to the so-called Inscription Stone. It bears ten lines on one side and six on the other. (See illustration.) Since Spirit Pond is well south of the Viking "barrier," the Inscription Stone has been declared a hoax, like the even-more-infamous Kensington Stone. But this classification has not deterred out-of-the-mainstream archeologists from studying it. After all, the Viking "barrier" was once located in Greenland! S. Carlson, in the latest issue of the NEARA Journal, has endeavored to translate the Inscription Stone. To her, it tells of a sudden storm and fearful Vikings trying to save their ship from "the foamy arms of Aegir, angry god of the ...

... swept past 951 Gaspra at a distance of 1600 kilometers, snapping photographs as it went. J. Veverka et al report below on what the photos showed: "We report the discovery of grooves in Galileo high-resolution images of Gaspra. These features, previously seen only on Mars' satellite Phobos, are most likely related to severe impacts. Grooves on Gaspra occur as linear and pitted depressions, typically 100-200 m wide, 0.8 to 2.5 km long, and 10-20 m deep. Most occur in two major groups, one of which trends approximately parallel to the asteroid's long axis, but is offset by some 15 , the other is approximately perpendicular to this trend. The first of these directions falls along a family of planes which parallel three extensive flat facets identified by Thomas et al. The occurrence of grooves on Gaspra is consistent with other indications (irregular shape, cratering record) that this asteroid has evolved through a violent collisional history." (Veverka, J., et al; "Discovery of Grooves on Gaspra," Icarus, 107:72, 1994.) Comment. The pits along Gaspra's cracks, as on Phobos, suggest the violent expulsion of gases. Where could these gases have come from? "Sandblows" are sometimes formed during terrestrial earthquakes as natural gases and other fluids are squeezed out of the earth's porous outer crust. Could Gaspra harbor primordial methane? If so, is it biogenic or abiogenic? Reference. An entire chapter on the anomalies of asteroids can be found ...

... Project Sourcebook Subjects Plane Weirdness Made Plain In SF#93, under the title: "Just Plane Weird," we questioned the long-term persistence of trailing vortices from aircraft wingtips. Could such vortices actually maintain their integrities for several minutes and thus produce the curious tubes of misty air and flapping sounds observed at the end of the Los Angeles airport runway? The answer seems to be YES, as confirmed below: "Wingtip vortices have a core diameter of 20 to 40 feet and, as they trail behind each wingtip, remain approximately two wingspans apart. Why don't they enlarge in radius and dissipate? The rapid acceleration at the outer edge of the vortex produces low pressure in the core, and this pressure differential creates enough centrifugal force to hold the system tightly together for three to seven minutes. After that, friction takes its course, breaking these stubborn twisters apart into mere turbulence." The rest of this article deals with how light aircraft can avoid these sometimes deadly horizontal "twisters." (Manningham, Micah D.; "Wake Turbulence," Private Pilot , p. 69, June 1994. Cr. W.A .

... controllable lucid dreams are the general rule. If you can't seem to get into lucid dreaming, apply to the Lucidity Institute, where you can purchase a Nova-Dreamer machine for $275. Thus armed, you can enter that Never-Never Land anytime you want. But how does one know he or she is dreaming lucidly? There is a simple test that is not only strange but probably anomalous. During your dream find a shop or traffic sign, even a dollar bill or newspaper. Then, find a word of four or more letters. Look away, and then look back. If the word has changed when you look back, you are in a lucid dream. For reasons unknown, the brain centers controlling lucid dreaming cannot consistently process words of more than three letters!
