European Southern Observatory, La Silla, Chile. Using the 3.6 -meter reflector and a photoelectric detector, astronomers recorded the occultation of a star by Uranus. The currently recognized rings of Uranus were duly noted as they dimmed the star's light, but so did seven other "objects." Observers at Las Campanas and Cerro Tololo, who were also monitoring the occultations, did see the seven extra occultations of the star. Clouds and faulty equipment have been ruled out. No one knows what caused the anomalies, (Anonymous; "More Mysteries of Uranus' Rings," Solar System Today, 3:56, 1981.) From Science Frontiers #17, Fall 1981 . 1981-2000 William R. Corliss ...

Science Frontiers ONLINE No. 17: Fall 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Was there really a big bang?Narlikar says, "Maybe not," and proceeds to tick off observational evidence against it. He begins, however, by pointing out the philosophical impasse encountered as Big Bang proponents look backward to time = 0 and earlier. Where did the matter/energy of the Big Bang come from? Was the venerable Law of Conservation of Mass/Energy violated? Big Bangers loftily dismiss such questions as "nonsense." Narlikar follows with some observational problems of the Big Bang: There seem to be objects in the universe that are older than the Big Bang age of the universe (9 -13 billion years); Quasar redshifts used to support the Big Bang theory may arise from the general expansion of the universe; The microwave background radiation of 3 K, which was gleefully embraced by Big Bangers as an echo of their version of creation, is actually of the same energy density as starlight, cosmic rays, etc., and need not have anything to do with the Big Bang; and The Big Bang Theory and General Relativity assume a constant G (the gravitational constant), but some recent lunar orbit measurements suggest that G is slowly decreasing! (Narlikar, Jayant; "Was There a Big Bang?" New Scientist, 91:19, 1981.) Comment. Perhaps the most disturbing aspect of the whole Big Bang business is the contempt with which theory supporters dismiss all objections. ...

... in helium-atom clusters Because spheres can be packed snugly together in certain configurations, one would expect the atoms of inert gases, such as helium, to cluster together in similar tightly packed groups. The numbers of spheres or atoms in these geometrically and energetically favored clusters are termed "magic." One would expect, for example, the number 13 to be magic because this would be the number of spheres fitting tightly into a 20-sided solid. Sure enough, when clusters of helium atoms are "weighed" with a mass spectrometer, the number 13 is strongly favored; so are 19, 25, 55, 71, 87, and 147. Some of these experimentally derived magic numbers can be predicted theoretically, but others were surprises. Some theoretical magic numbers did not turn out to be magic in reality; notably 7, 33, and 43. Clearly nature has other criteria for "magickness" than the physicists.

... separate developments of eyes among disparate terrestrial organisms may infer some unrecognized directing factor in evolution that would force him to revise his estimate upwards drastically. On the other hand, those 15 eyes might indicate a common, but still undiscovered, eye-possessing ancestor far back along evolution's track. The fossil record might be mute on this matter because eyes are soft tissues that are rarely preserved or perhaps because many eyes were jettisoned because the organisms didn't need them, as cave dwellers are wont to do with surprising rapidity. Some of the letters responding to Tipler questioned whether an intelligent civilization would be stupid enough to build self-reproducing von Neumann machines for galactic exploration. Wouldn't it be far more fun to go in person rather than by proxy? And, some pointed out, von Neumann machines would be ravenous consumers of energy and materials and might turn on man as an unnecessary competitor. Machines are not immutable. Space radiation and other environmental factors might alter computer programs and memories to drastically affect the behavior and objectives of such machines. Actually, as one letter writer observed, the earth has already been invaded by a self-reproducing, energy-hungry machine with exploratory tendencies -- man!

... ". .. how did the surrounding rocks crystalize rapidly enough so that there were crystals available ready to be imprinted with radiohalos by alpha-particles from Po218 ? This would imply almost instantaneous cooling and crystallization of these granitic minerals -- and we know of no mechanism that will remove heat so rapidly; the rocks are supposed to have cooled over millennia, if not tens of millennia." In coalified wood dated as older than 200 million years, the ratio between U238 and Pb206 should be low. It is actually very high. "Thus ages of the entire stratigraphic column may contain epochs less than 0.001% the duration of those now accepted and found in the literature." Diffusion calculations insist that Pb in zircon crystals found in deep granite cores at 313 C should diffuse out of the crystals at the rate of 1% in 300,000 years. No loss of Pb can be detected at all. Therefore, the granite must be younger than 300,000 years. (Gentry, Robert V.; "Creationism Discussion Continued," Physics Today, 35: 13, October 1982.) Comment.

... maverick items in his catalog are objects that seem physically related but have radically different redshifts. Examine for instance the illustration, which shows the large galaxy NGC 7603 (possessing a supposed recessional velocity of 8,700 km/sec) and its smaller companion at the end of the filament, which recedes at the much higher velocity of 16,900 km/sec. According to the Theory of the Expanding Universe, the greater the recessional velocity (as measured by the red or Doppler shift), the farther away the object is. But Arp's many examples of physically connected galaxies with wildly different redshifts suggest that some of the disparities in redshifts may actually be due to the related objects flying apart from each other. In the illustration, the small companion might have been "shot out" of its parent galaxy at high velocity by some unappreciated galactic gun. (Arp, Halton C.; "Related Galaxies with Different Redshifts?" Sky and Telescope, 65:307, 1983.) Comment. Left unsaid in Arp's article is the possibility that redshifts are not good measures of distance. If they are not, doubt is cast on the Theory of the Expanding Universe and the reality of the Big Bang itself. Some astronomers, according to news items in scientific publications, have heard enough about discordant redshifts and would rather see scarce telescope time used for other types of work! Reference.

... and even ancient Peruvian balloon technology. The fact of the matter is that archeological evidence is pretty convincing that the Nazca Indians constructed the lines about 500 A.D . But did they have extraterrestrial help or use some advanced technology? The author of the subject article, with the help of a few friends, answered these questions quite convincingly -- in the negative -- in the summer of 1982. Using sticks and string, they scaled up a small copy of the famous Nazca "condor" into a 440-foot replica of the real thing on a Kentucky landfill. 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. (Nickell, Joe; "The Nazca Drawings Revisited: Creation of a Full-Sized Duplicate," Skeptical Inquirer, 7:36, Spring 1983.) Comment. While some of the animal figures and arrays of lines may have had ritual or archeoastronomical purposes, others seem too complex for such simple explanations. Of course, to the Nazca Indians the purpose was probably simple and obvious. Reference. Much more on the Nazca lines appears in our Handbook: Ancient Man. ...

... minutes. It is not the "forbidden" character of the spectral likes that disturb the astronomers. (" Forbidden" simply means "improbable" in spectroscopy!) Rather, it is the half-hour variations that pose the dilemma. This is because most astronomers are convinced that the said forbidden lines are emitted by regions of the quasar that are 100-10,000 light years across. A disturbance or physical change leading to a variation in intensity, even travelling at the speed of light, could not begin to move across this huge region in half an hour. Yet, the changes in intensity seem to be there, inferring a physical change that travels perhaps a million times faster than physics permits. Variations in intensity decades long would be acceptable, but half an hour is out-of-the-question! The author of this referenced comment in Nature believes that the observational procedures employed must be at fault. (Gaskell, C. Martin; "Spectra That Defy Explanation," Nature, 304:212, 1983.) Comment. This possible anomaly is closely related to the so-called superluminal velocities also observed in quasars, in which physical effects seem to travel faster than light. Apparently something is very wrong in our model of a quasar, or our distance scale, or even our basic physics. From Science Frontiers #29, SEP-OCT 1983 . 1983-2000 William R. Corliss ...

... solar companion (MSC), he discovered that the perihelia of the outer planets (orbital points closest to the sun) were being disturbed with an average period of 11.2 years. This is almost exactly the sunspot period. This serendipitous finding caused Bagby to wonder whether some common influence was causing not only the sunspot cycle and those perturbations in outer-planet perihelia but also cyclic volcanic and seismic activity on earth. Some correlations indeed do indicate a sun-earth link of some sort. Bagby suggests two possibilities: (1 ) Mutual resonance effects between the planets, (2 ) The effects of a massive solar companion. (Bagby, John P.; "New Support for the Planetary Theory of Sunspots," privately circulated paper, 1983.) Comment. Even "farther out" is the thought that gravitational waves or some unrecognized influence from the galaxy or beyond causes the whole solar system to "ring."

... new eruption theory assuming the minor bodies of the Solar System to have formed in explosions of the massive ice envelopes saturated with electrolysis products on distant moon-like bodies of the type of Ganymede and Callisto." (Drobyshevski, E.M .; "Combustion as the Cause of Comet P/Halley's Activity," Earth, Moon, and Planets , 43:87, 1988. Cr. L. Ellenberger.) Drobyshevski's combustion theory assumes a "local" origin (within the solar system) for Halley. But measurements of the ratio of carbon-12 to carbon-13, made during the 1986 flyby, produced a ratio of 65:1 . This compares to 89:1 for solar system material. The 65:1 ratio, it turns out, is more typical of interstellar material. This datum seems to place Halley's birthplace somewhere outside the solar system. (Weiss, R.; "Carbon Ratio Shows Halley May be Alien," Science News, 135:214, 1989.) As if all this were not bad enough, calculations of the amount of matter expelled from Halley and incorporated in known meteor streams allow an estimate of Halley's residence time in the inner solar system. (One has, of course, Halley's present mass, but must estimate its original mass!) The conclusion is that Halley has spent only 23,000 years in its present orbit!

... Project Sourcebook Subjects The Great Wall Of The Incas The Inca's ability to build with stone is well-known. But one of their most ambitious projects is rarely mentioned in the literature and is poorly investigated in the field. Probably no more than 150 miles in length, it cannot compare with China's Great Wall. Still, it is built at altitudes of 8,000-12,000 feet in extremely rugged terrain. It runs along high ridges and is studded with stone forts at strategic intervals. Even though the Inca Wall is only a few feet high, it would certainly slow down a force charging up precipitous terrain at two miles altitude. The true extent and condition of the Inca Wall is not accurately known. Only a few easily accessible sections have been checked out. The theory is that the Incas built it to discourage invasions by lowland Indians. Like all Great Walls, it seems to have met with only small success. (Paddock, Franklin K.; "The Great Wall of the Inca," Archaeology, 37:62, July/ August 1984.) Comment. The Great Wall of the Incas is located in Bolivia. There is another Great Wall in Peru that seems to have been built by the Chimu people, perhaps to defend themselves against the Incas! The Chimu Great Wall averages 7 feet in height and reaches 20-30 feet where it crosses gullies. Also incompletely explored, it may run some 60 miles.

... photographs for some 50 kilometers. The material making up the strata is clearly different from that of the valley walls. After the layers were deposited, they were deeply eroded by some event in Martian history that seems related to the formation of the great outflow channels associated with Valles Marineris. The author of this American Geophysical Union paper concludes: "The morphology and history of the sediments are consistent with deposition in standing bodies of water early in Martian history." (Nedell, Susan S., and Squyers, Steven W.; "Geology of the Layered Deposits in the Valles Marineris, Mars," Eos, 65:979, 1984.) Comment.

... like a balloon? Hugh Owen answers in this way: "The geological and geophysical implications of such Earth expansion are so profound that most geologists and geophysicists shy away from them. In order to fit with the reconstruction that seems to be required, the volume of the Earth was only 51 per cent of its present value, and the surface area 64 per cent of that of the present day, 200 million years ago. Established theory says that the Earth's interior is stable, an in ner core of nickel iron surrounded by an outer layer that behaves like a fluid. Perhaps we are completely wrong and the inner core is in some state nobody has yet imagined, a state that is undergoing a transition from a high-density state to a lower density state, and pushing out the crust, the skin of the Earth, as it expands."

... my mother in the living room, both facing the windows. There was a very loud peal of thunder and a loud crack, rather like the little explosion of a Christmas cracker greatly magnified. I was at the sink, close to the window, on the ledge of which stands an electric Corvette water heater, plugged in but not switched on. Beside me, about four feet from the ground and two feet to the left of me, at the moment of the crack, there appeared for a second or so, electric blue flashes, six to eighteen inches in length coming from a white centre. I felt nothing, but was startled. There was no damage to the water heater or anything else. Just as I exclaimed at the blue flashes, I heard my mother cry out and ran to her in the living room. She was sitting in a chair about ten feet from the window, under which stands the television set, plugged in but not switched on. About eight feet from the floor and four feet in front of the double-glazed window (i .e . between the television and the fireplace, but not quite over or opposite either), appeared an orange fireball, rather smaller than a football, with straight lines of orange light, varying from about one to two feet in length coming from it in all directions.

But a colony of a million army ants is a sophisticated "super-organism." The colony carries out its legendary raids and can even keep nest temperatures constant to within a degree. An army ant colony seems en dowed with an intelligence far beyond that of any individual ant. N.R .Franks speculates thus: "It seems that intelligence, natural or artificial, is an emergent property of collective communication. Human con-sciousness itself may be an epiphenomenon of extraordinary processing power. Although experts prefer to avoid simplistic definitions of intelligence, it seems clear that all intelligence involves the rational manipulation of symbolic information. This is exactly what happens when army ants pass information from individual to individual through the 'writing' and 'reading' of symbols, often in the form of chemical messengers or trail pheromones, which act as stimuli for changing behavior patterns." During its 20-day stationary phase, an army ant colony scatters about 14 foraging raids directed 123 apart. The heavy line indicates the colony's path during the nomadic phase. In the body of his article, Franks describes two remarkable capabilities of an army ant colony: time-keeping and navigation. The outward manisfestation of time-keeping is in the precise timing of the colony' ...

... phenomenon, in the view of many active in the field, is a spectacular new form of lattice-induced nuclear energy whose mechanism is still poorly understood -- as the mechanism of low-temperature superconductivity was for decades. That the nuclear products that have been found so far are incommensurate (by conventional theory) with the non-chemical-magnitude excess energies simply means that the results have to be explained by new physical mechanisms." Of opposite polarity were remarks by J.R . Huizenga, author of the debunking book: Cold Fusion: The Scientific Fiasco of the Century : "In contrast to Mallove's declaration that cold fusion is a "spectacular new form of lattice-induced nuclear energy," I conclude that there is no persuasive evidence to support this far-out claim. Instead, cold fusion as a nuclear process producing watts of excess heat is more likely than not to be an example of pathological science." Of historical interest in this collection of correspondence in Physics Today was S. Bashkin's mention of the 1926 experiments of F. Paneth. His results were essentially identical to those of S. Pons and M. Fleischmann that began the present cold fusion furor. Paneth detected helium after passing an electrical current through hydrogen-laden palladium! But he later retracted his conclusions.

Continuing our SF#105 analogy between geofacts and biological organisms -- both supposedly products of random processes and subsequent selection -- we ask how long it would take for enough random mutations to accumulate, in the proper order (as with the geofact flake scars) to evolve a new species, with the help of natural selection (corresponding to Guidon et al sorting out their flaked stones)?

... a platypus-like creature lived long before the Age of Mammals. These early platypusses had teeth in the adult phase, whereas their modern relatives replace their baby teeth with horny plates -- another innovation. Therefore, far from being a hodgepodge of parts left over from bird and reptile evolution, the platypus has actually pioneered several zoological features. Very curious is the fact that the platypus is in many ways like the beaver -- a very, very distant relative both in distance and position on the Tree of Life. Both platypus and beaver are furry, aquatic creatures with webbed feet and a large, flat tail. We have saved the strangest part for the end! Platypusses, being Monotremes (one-enders) have a common vent for waste and reproduction. Beavers, it turns out, are among the very rare placental mammals that (like the birds) possess a cloaca -- a common vent for urine and excrement. (Hoffman, Eric; "Paradoxes of the Platypus," Scientific American, 264:18, March 1991.) Comment.

... phenomena. Neither article mentioned the work of the other! Both groups of scientists processed massive quantities of earthquake records to form "seismic images" of structures deep in the bowels of the earth. (The technique is called "seismic tomography.") Both groups have discerned huge slabs of crust that were once on the planet's surface but were subsequently thrust (" subducted") down under the continents. These slabs are now hundreds of kilometers below the surface, and they have dragged water along with them. In fact, their water inventories may rival today's surface oceans; they may even have been surface oceans themselves millions of years ago before they descended into the infernal regions. Only a few years ago, all geologists maintained that all water in subducted slabs was squeezed out of the rocks by immense pressure and later reappeared at the surface as volcanic steam. Deep ocean #1 . G. Nolet and A. Zielhuis, Princeton seismologists, report a huge reservoir of water about 900 kilometers under present-day Europe.

... grow near Chaco Canyon today. There is no consensus as to where all these trees were felled. S. Durand, an archeologist from Eastern New Mexico University, Portales, has developed a technique for identifying the sources of logs. He tries to match trace elements in the Chaco Canyon logs with those in living trees in today's forests. The different bedrocks underlying the various forests supply different quantities of such trace elements as barium and manganese. Preliminary results suggest that the early building period in Chaco Canyon, circa 900 AD, employed trees from many different sites. During the peak building period a century later, all logs used carried the same concentrations of trace elements and, therefore, probably came from the same forest. Durand's next step is to locate this forest and figure out how the builders of Chaco Canyon, the Anasazi, managed to tote the logs, some weighing 600 pounds, 50 miles or more.

... lake. Where did all these species come from, considering that their little islands were bone dry just a century ago? Goldschmidt writes: "Cichlids that inhabited these exposed rocks would have suffocated, unless they had already left for wetter climes. Yet today, species that do not exist anywhere else can be found near almost every rocky island. From an orthodox point of view, the most plausible explanation for this is quite surprising: many color forms as well as biological species developed over a period of less than two hundred years." This is certainly explosive speciation -- real biological punctuation! But, perhaps as water levels fell, the original cichlids found refuges in surviving pools and then repopulated the lake when the waters rose. But is it reasonable to believe that they all sorted themselves out so perfectly that many species are found nowhere else in the lake? The probability seems high that cichlid speciation has been very rapid -- too rapid, one would think for random mutation and the slow feedback of natural selection to accomplish this daunting task in just a century or two. Might there not be some additional nonsupernatural factor at work? (Goldschmidt, Tijs; Darwin's Dreampond , Cambridge, 1996, p. 125.) From Science Frontiers #110, MAR-APR 1997 . 1997-2000 William R.

Wilder to have a look for himself. After all, when the conservative Wall Street Journal admits to being "baffled," there must really be something to the phenomenon! Spook Hill is located on a section of road in Lake Wales, Florida. Here, at Spook Hill, the road "seems" to slope downhill, but yet cars in neutral apparently roll up the incline. Wilder, a member of the Tampa Bay Skeptics, made several pertinent observations during his investigation: "( 1 ) Although the phenomenon is striking when one approaches Spook Hill from one direction, if one gets out of the car and looks back, it is quickly apparent that one's senses have been deceived. Because the illusion fails when one looks in the opposite direction, the road has been made one-way, so that tourists will not be disappointed! "( 2 ) A storm drain is positioned at the true low point of the road, and cars seem to roll up to the drain. Water, in its gravitational wisdom, knows where to go!
