... doubts permitted; here the Book of Science is closed! It was like a breath of fresh air to read this sentence in Sky and Telescope: "Scientists are still unable to confirm the existence of even a single black hole, despite a widespread belief that such things should, and indeed must, exist." This single sentence won't change anything, because everyone is comfortable with black holes. They are part of the (often false) reality that the media smothers us with. Actually, there are two places where black holes "might" dwell, based upon the anomalous behavior of matter around these regions: (1 ) at the centers of some galaxies, including our own Milky Way; and (2 ) as unseen components of some close double stars, where the mass of the unseen companion is too great for it to be an ordinary neutron star. W. Kundt and D. Fischer, at Bonn University, have recently concluded that the second possibility is better explained without resorting to black holes. For example, a neutron star with a massive accretion disk might suffice. As for black holes at the centers of galaxies, with masses of several million suns, gravitationally sucking in surrounding matter and careless spaceships - well, they are possible. Unfortunately, galac-tic centers are too far away and obscured by dust for us to be certain what lies at their cores. Black holes are really only surmise; although they make good copy!

Three individuals were monitoring nearby fields for crop-circle phenomena. Instead, they observed a strange, but possibly related, luminous mass. R.L Goold described it in the following words: "Suddenly, at 2.55 a.m ., birds began singing which heightened our alertness and made us check wrist watches. It was soon quiet again, but at 3.00 a.m ., almost exactly, I spotted a tube of light to the northeast descending vertically beneath a cloud in that part of the sky. Most of the remainder of the sky was clear and starry. The tube extended steadily in length as we watched, and its milky-white colour seemed to be due to a self-luminoscity like one might expect from the electrical effect known as plasma. As it came down against the black sky and neared the ground, the tube began to broaden, and branched out to give two opposed arms, as indicated in the drawing, forming a design in the air with rounded ends. Then the tube dissipated from the top downwards, and disappeared into the horizontal arms which themselves proceeded towards the ground out of sight beyond the hill peaks. No noise was heard. The whole phenomenon lasted about six seconds." The trio of observers used their fingers held at arm ...

The rock mass subsequently launched from the cliff and free-fell ballistically an estimated 550 m before impacting approximately 30 meters from the base of the cliff in the Happy Isles area of the valley floor in Yosemite National Park...This rock fall was well recorded by 3 UC Berkeley (BDSN) and Caltech (TERRAscope) broadband seismographic stations and 15 shortperiod seismographic stations (operated by the USGS in Menlo Park and the University of Nevada, Reno).

Females of these species usually survive to breed a second and even third year. The poor males, however, succumb due to "elevated levels of free corticosteroids in the blood and associated disease such as hemorrhagic ulceration of the gastric mucosa, anemia, and parasite infestation." In short, they seem programmed to die after mating, like the male octopus. And one wonders why evolution has wrought this mass die-off. In their studies of marsupial mice, C.R . Dickman and R.W . Braithwaite have extended the phenomenon to two new genera: Dasyurus and Parantechinus . They have also found that the phenomenon is a bit more complex. First, in P . apicalis, the male die-off occurs in some populations and not others. In D. hallucatus , the die-off may occur in the same population in some years and not others. Furthermore, the females of this species may on occasion all die off, too -- but after giving birth, of course.

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.

Already this maverick planet is drifting off the orbit predicted just 10 years ago using the best data and solar-system models. All of the outer planets, in fact, confound predictions to some degree. In addition, some long-period comets have anomalous orbits. Astronomers have been aware that something was wrong for decades and anticipated finding a trans-Neptunian planet large enough to perturb the outer solar system. The discovery of Pluto did not help matters; it is much too small. The most popular explanation of the orbital anomalies relies on a large, still-undetected planet, possibly 3-5 times the mass of the earth, swinging sround the sun at some 80-100 Astronomical Units. But many have searched and no one has found anything. Planet-X , as it is often called, is just another bit of "missing mass." Thomas C. Van Flandern and Robert Harrington propose that all the obvious orbital damage in the outer solar system is the result of a single encounter between Neptune and another body, call it Planet X if you wish, that was passing through the outer reaches of the solar system.

"Clusters of galaxies can eject members by a gravitational slingshot process, with one galaxy after another being accelerated through the dense centre of the cluster and fired out into the Universe at large. If this happens, the ejected galaxies are moving at more than the escape velocity from the system, so estimates of the total mass in the system based on the assumption that all the galaxies are in bound orbits will be incorrect" (Anonymous; "Expanding Clusters Confuse Astronomers," New Scientist, p. 13, March 2l, 1985.)

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.

Furthermore, the fossils now coming to light in the Gobi sandstones are not only abundant but also preserved with great fidelity. For example, at Ukhaa Tolgod, paleontologists are excavating the planet's largest assemblage of fossil vertebrates from the end of the Cretaceous Period (71-75 million years ago). In 1993, about 1,000 fossils representing 20 species of mammals and reptiles were collected. Amazingly, these bones were not disarticulated, scattered about, or severely worn. It was obvious that the Ukhaa Tolgod animals had been very suddenly engulfed by a "tidal wave" of sand. It was a catastrophic event of some sort. But what kind of catastrophes occur on desolate, riverless deserts? Wind is always blowing sand about and dunes creep along in deserts, but healthy animals easily avoid burial. Of course, there are rare, sudden downpours even on the Gobi. But one would expect this rain to be quickly absorbed by the sand. Intrigued by the evidence of unexpected catastrophism in the Gobi, scientists from the American Museum of Natural History first took a look at Nebraska's strange Sand Hills.

Under the broiling Egyptian sun, dust devils launched themselves naturally every few minutes from a tented camp near the airfield where Swinn taught. Curiously, the devils often were born in pairs; a big one followed by a modest little chap following behind by 100-150 yards. The devils ranged from just a foot or so in diameter to 500 yards and more. The giants were majestic masses of swirling sand that moved along at leisurely paces. These appeared harmless enough, but stepping through the outer wall into the vortex sucked the air out of the lungs. "Outside our hangar there is a large stretch of wind-sheltered concrete which becomes intensely hot. In this area, close to the foot of the hangar, one can start up one's own little devils on occasions by a quick sweep of a signalling bat (which is shaped like a large ping-pong bat) from shoulder level in circular and downwards direction to a point almost touching the ground; one must step rapidly back or the vortex that is set up is spoilt.

Now we find that Florida doesn't even belong to North America; it is an interloper, an "exotic terrane." How does one know this? Three facts hint that Florida doesn't belong: When pre-Cenozoic land masses are fitted together, assuming the truth of continental drift, an awkward overlap arises that suggests that Florida was not always where it is today; The latest paleomagnetic measurement of Florida's Paleozoic latitude is consistent with it being part of Gond wanaland rather than at its present latitude; Radiometric dating of zircons retrieved from a core extracted from Northern Florica yield an age of 16501800 million years. There are no known source rocks in the southeastern U.S . that old; Africa and South America are likely sources of such zircons.

"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." Whence these interplanetary dust clouds? The author of this article ruled out terrestrial volcanism (an insufficient source of iridium) and encounters with asteroids and cometary tails (too infrequent to account for the long periods of high dust levels).

Smitt in his Scandanavian Fishes (1895) says that eels knot themselves together in bunches 'up to a fathom in circumference' and are seen rolling along the stream beds, or, strangely, resting in this position. On 17 August 1935, fishery scientist J.C .

Ob-viously the Principle of Superposition is contradicted in such situations. Two possible explanations exist for these inverted strata: (1 ) The dating of the rocks is incorrect; or (2 ) Geological forces somehow slid the older rocks over the top of the younger rocks. Few mainstream scientists give any thought to the first possibility because it implies that evolution did not proceed as presently envisioned. (Rocks are often dated by their fossil contents.) So, geologists are left with the problems of sliding great masses of rock over rough surfaces for great distances. Sketch of the forces acting upon a thrust block being pushed by a wedge-shaped driver Low-angle thrust faulting is not a trivial geological process. To illustrate, the Lewis Overthrust in Montana and adjacent Canada involves the shoving of a block of old strata hundreds of feet thick, hundreds of miles long, over younger rock for a distance of possibly 50 miles. In contemplating such overthrusts, one immediately comes face to face with the Mechanical Paradox. Brief-ly, given the coefficient of friction between the layers of rock, the weight of the thrust block, and the mechanical strength of the rock being pushed, it can be shown that pushing the thrust block at the rear edge will crush it long before it begins to slide.

The tiny, often-illustrated teardrop- and button-shaped tektites clearly seem to have been formed when an extraterrestrial object smashed into the earth, melted terrestrial rock and soil, and splashed the fluid droplets over thousands of kilometers of Australia and Southeast Asia. Solidifying in flight, these par-ticles fell by the millions. Aerodynamically sculpted Australasian tektite But another type of tektite is also found in Southeast Asia. These are the layered or Muong-Nong tektites, which are not aerodynamically sculptured. They come instead in large, irregular masses, 3-20 centimeters thick, weighing up to 24 kilograms. Their layered appearance is thought to result from flow and stirrings as they solidified in small pools of melted rock and soil splashed from nearby impact craters. These irregular chunks of solidified melt could not have traveled great distances like their streamlined brothers. They lie at most only a few crater diameters from their parent craters. Since layered tektites are found over an area 800 x 1140 kilometers in extent, and they are not far-travelers, Southeast Asia must have been peppered with many small cosmic projectiles 700,000 years ago (the disputed age of the event).

... ideas (perhaps "speculations" is a better word) that was recently unleashed by L. Smolin in the journal Classical and Quantum Gravity (9 :173). At stake here is the very nature of Nature herself. We begin with the notion of anthropic cosmology, in which the physical constants of the universe are identified as having just the "right" values to allow the existence of stars, planets, carbon compounds, and the other ingredients of human life. (Just why this state of affairs prevails is a question rarely addressed!) Adherents of anthropic cosmology hold that our "human-friendly" universe is just one of many universes populating a larger metauniverse. These "other" universes are thought to have different values of the fundamental physical constants (viz., the mass of the proton) and, in consequence, wildly different forms of life. In nonhuman universes, there could even be entities for which our word "life" is inadequate. The second idea is that of an oscillating universe. In this concept, universes expand just so far and then collapse back into the "singularities" (i .e ., black holes) from which they arose. Then, Phoenix-like, they bounce back and reexpand into new universes -- ones with slightly different physical constants. These rebounding universes are in a sense mutated universes, which have been slightly modified during the physical trauma of collapsing into singularities. Now comes a stimulating thought. The most abundant sort of universe occupying the metauniverse will be that type that generates the most new black holes ...

Two of many cosmoseisms felt during the meeting in Poland are recorded below: "Halton Arp, Max-Planck Institute for Astrophysics, spoke about his "Variable Mass" cosmology. He pointed out the need for cosmologies to explain why quasar redshifts cluster near 0.3 , 0.6 .. ., with the grouping just below z = 1.2 dominating all others; and why certain classes of stars have significant excess redshifts. He also pointed out the inconsistency that local galaxy groups seem to have velocity dispersions of less than 100 km/s , while distant groups seem to have members with dispersions up to 1000 km/s . "Jack Sulentic spoke about multiple redshifts seen in some quasars and AGNs. Line profiles come in all types; symmetric, double-peaked, and asymmetric. Relative shifts are both toward the red and the blue. Arguments against an accretion disk/black-hole model were reviewed. Apparently a non-Doppler redshift-blueshift mechanism is needed. For example, one broad line (in 1404+ 28) shifts back and forth by 1000 km/s relative to another narrow H-line, with an average offset of 2000 km/ ...

Being so weighty they strongly perturb the orbits of comets, deflecting many away from the inner solar system, where we reside. Calculations by G. Wetherill, at the Carnegie Institution, reveal that if Jupiter and Saturn were only 15 times the mass of the earth, the earth would have been devastated every 100,000 years by giant comets, instead of about every 100,000,000 years, as indicated by the geological record. Under such intense bombardment, it would probably have been difficult for advanced life forms to develop.

In fact, we really must, because 1987A is more than usually anomalous. The newspapers have oohed and aahed about this rare opportunity scientists have to study a nearby supernova. However, instead of getting closer to a final understanding of supernovas, 1987A seems to be confounding the theorists. No one can determine which star, if any, blew up. The 12th magnitude star Sanduleak -69 202 was first fingered, for it is located in the proper spot. But it is still there, apparently unchanged, as is a still fainter companion. The problem is that if 1987A really originated with an even fainter star, such a star would not have enough mass to go supernova. Part of 1987A's spectrum, its luminosity evolution, and precursory neutrino burst all indicate a Type-II supernova. Unfortunately, its ultraviolet spectrum is that of a Type-I supernova. Also anomalous are its high rate of evolution and low luminosity (only magnitude 4.5 instead of the predicted 2 +. Japanese apparatus located in a deep mine near Kamioka detected a burst of neutrinos about 22 hours before 1987A flared into the visible spectrum. This fits Type-II supernova theory, but the Mont Blanc equipment detected a neutrino burst just 4.6 hours before the flare-up.

A logical question is: Can life forms and/or chemical precursors of life be transported thus across the far reaches of the solar system? Can one planet infect another ballistically? An analysis by M.K . Wallis and N.C . Wickramasinghe is rather warm towards this idea: "The mass of escaping ejecta from the presumed 10-km comet that caused the 180-km Chicxulub crater, with a radius of roughly 10 km and 1 m deep, amounted to ~300 Mm3 , of which one third may have been rock and 10% higher-speed ejecta that could have transited directly to Mars. It may have taken 10 Ma to impact Mars but...the probability is not exceedingly low but 0.1 -1 %. "The survival and replication of microorganisms once they are released at destination would depend on the local conditions that prevail. Although viability on the present-day Martian surface is problematical, Earth-to-Mars transfers of life were feasible during an earlier 'wet' phase of the planet, prior to 3.5 Ga ago.

On July 26, 1983, Io suddenly brightened by about 50% for just under 2 minutes. The "flash" represented an emission of energy of some 1028 ergs, which is equivalent to the impact on the satellite of an ice mass 5-kilometers in diameter moving at 60 km/sec. This collision interpretation is encouraged by the 1994 impacts of cometary fragments on Jupiter proper. In the case of Io, however, there is another possibility: electrical arcing. Io's volcanoes are prodigious spewers of metallic sodium, and T. Gold has speculated that colossal arcs may occur in this conducting environment as Io cuts through Jupiter's magnetic field. (See Science Frontiers #10. (O 'Brien, Roger; "Has Jupiter Flashed Before?" British Astronomical Association, Journal, 104:6 , 1994.) Comment.

Frank and his associates at the University of Iowa have speculated that the earth is continuously and copiously bombarded by small, icy comets. Not just a few now and then, but a steady rain so intense that over geological time some major geological consequences must ensue. (See SF#44.) Some observers commented that surely these scientists have thrown away their careers by suggesting something so ridiculous. But the data are there -- in the form of dark spots on satellite images of the earth's dayglow -- and late results continue to support this far-out interpretation, ridiculous or not. "The mass of these objects is estimated at about 108 gm each, and the total flux is about 107 small comets per year. If this flux is representative of the average flux over geologic time, then the water influx is sufficient to fill the Earth's oceans. The fluxes of these objects are also large for all the planets outside the orbit of Earth. Considerations of thermal stability imply that the fluxes of comets that impact Venus are considerably less. The outer giant planets may be significantly heated relative to solar insolation by the small-comet impacts. For example, the total energy input due both to solar insolation and comet impacts may be similar for Uranus and Neptune. Thus it is possible that the temperatures of these two planets are similar, even though Neptune is farther from the Sun ...

That is, did two clouds of debris simultaneously collect and coalesce into two rough spheres, which then began orbiting about a common center of gravity? Or, perhaps the earth and moon were once a single mass that ultimately fissioned due to the gravitational tugging of a passing massive object. If either of these scenarios were correct, earth and moon would have similar bulk compositions. This, however, does not seem to be the case. The abundance and distribution of iron on the moon's surface, as measured by the lunar probe Clementine , indicates that the moon is richer than the earth in refractory (high meltingpoint) compounds. The moon, therefore, almost certainly originated elsewhere, contrary to what most astronomers have longbelieved. Given the constraints of celestial mechanics, the most likely hypothesis postulates a colossal impact involving protoearth and the interloping protomoon. After considerable havoc, the two battered spheres settled down into their present configuration. Thus expire the two most popular theories of the moon's origin.

"The rule actually used supposes that the question whether each point in a newly added layer will (or will not) be occupied by a galaxy is mostly determined by the occupancy of the five nearest neighbors in the previous layer, but for good measure, there is a random variable to introduce an element of white noise to the system. To make the process a little more interesting, the determination whether a new site is occupied depends on whether a number characteristic of that site, and calculated by simple arithmetic from the corresponding number for the five nearest neighbors in the preceeding layer, exceeds an arbitrarily chosen number."

Quoting the final paragraph: "Intermittent natural gas blowouts from hydrate-associated gas accumulations, therefore, might explain some of the many mysterious disappearances of ships and planes -- particularly in areas where deep-sea sediments contain large amounts of gas in the form of hydrate. This may be the circumstance off the southeast coast of the United States, an area noted for numerous disappearances of ships and aircraft."

The largest "nugget" of nearly pure copper comes from Lake Superior and weighs almost 46 tons! But the Corocoro mines are rich in another way; copper "pseudomorphs." In copper pseudomorphs, copper ions insidiously invade crystals of other minerals and assume their shapes. Copper pseudomorphs of aragonite, a form of CaCO3 , are common. Aragonite sometimes occurs as short, tabular, hexagonal prisms, as shown in the sketch. Under the water table, in a copper-rich area, copper ions in solution "attack" aragonite crystals. First, they oust and replace the outer layers of CaCO3 , gilding the aragonite crystal with a thin layer of pure copper. Then, they work inwardly and eventually usurp the whole crystal and take on its shape. Even stranger are those hexagonal crystals that are pure aragonite in the top half and pure copper in the bottom half. Mineralogists speculate that these formed along the edge of the water table.

(SF#60/160) The subject then was the strange mesmerizing effect electrical equipment has on ants. They dote on airport runway lights, household electrical meters, and in particular electrical relays, where they congregate en masse. Now, a decade later, we discover that they are also not adverse to exploring microwave ovens -- even when they are turned on! We cannot explain the attraction of electrical relays, but we do know how ants survive in humming microwave ovens. It is because the microwaves inside the oven form standing waves. Energy is high in some areas -- ants would fry there -- and weak elsewhere. Ants seem to be able to find these lowenergy refuges and survive very nicely -- perhaps on the food you were planning to consume! (Anonymous; "Them!" New Scientist, p. 109, July 31, 1999. Comment. You can map you microwave's standing waves by filling a flat tray with marshmallows. A pattern of toasted and untoasted marshmallows will appear post-zapping.

Science Frontiers ONLINE No. 27: May-Jun 1983 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Great Balls Of Snakes Most garter snakes in the northern states spend the winter in communal dens below the frost line. Some dens host as many as 10,000 to 15,000 redlined garter snakes, which emerge en masse in the spring. Although garter snakes cannot survive freezing temperatures, they apparently do not congregate in such enormous numbers to keep warm, for sexually immature garter snakes commonly hibernate alone. Big concentrations of sexually mature garter snakes seem to be part of the reproduction strategy of the species. In the big aggregations, males usually outnumber females by 50-1 . As each female emerges in the spring, she is immediately mobbed by dozens of males. So-called "mating balls" of up to 100 males and a single female are formed. Naturalists commonly explain the wintering concentrations and mating balls as clever schemes evolved to maximize reproduction with minimum expenditure of energy. This article accepts this theme uncritically. (Lynch, Wayne; "Great Balls of Snakes," Natural History, 92:65, April 1983.) Comment. Evolutionists tend to "explain" facts in a circular fashion; that is, only the most efficient reproducers (or "fittest") survive, therefore those that survive must be the best reproducers. While the garter snake strategy has some advantages in terms of getting male and female together, things may have gone too far. For example, one communal den was flooded, ...

... Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A Real Death Star As reported in SF#31, the geological record seems to show that widespread biological extinctions have occurred about every 26 million years. Coupled with this is Walter Alvarez's recent observation that terrestrial impact craters 10kilometer-diameter and up have been blasted out episodically -- every 28.4 million years on the average. This figure is close enough to 26 million years to impel some astronomers to search for a periodic source of cosmic projectiles. R.A . Muller and M. Davis, at Berkeley, think they have found one. They postulate that the solar system is really a double-star system. Our sun's companion star has only about 0.1 solar mass and is so faintly luminous that we have not found it visually. It does, however, now cruise along its orbit some 2.4 light years away. But it will be back! In fact, it returns every 26 million years to jostle the Oord Cloud of comets that hovers on the fringe of the solar system. This nudging periodically sends a large shower of comets careening around the inner solar system. The earth intercepts one or more of these projectiles each visit and -- bang -- we have new craters and another biological catastrophe. (Anonymous; "A Star Named George," Scientific American, 250:66, April 1984.) Comment, Ho hum! Still another cometary impact scenario. Ignatius Donnelly was pretty convincing in this matter a century ago. ...

... well above 100 kilometers where the atmosphere is too thin -- essentially a good vacuum -- to cause frictional heating and consequent vaporization. We mentioned this conundrum briefly in SF#125. We now have the scientific details at hand concerning the supporting observations made during the November 1998 Leonid bombardment. The observations were made by an international team in China. Photographic cameras were employed as well as an all-sky TV camera equipped with an image intensifier. All photographed meteors began to visibly burn up below 130 kilometers, but the TV camera consistently picked up the same meteors at higher altitudes. Both sets of cameras recorded the same final burn-up heights. The most startling observation was a meteor that the TV camera detected at roughly 200 kilometers altitude. The highest observed Leonid meteor with initial mass of about 1 kg started radiating at an altitude of almost 200 km. The origin of meteor radiation at such high altitudes is still not well understood and more detailed observations will be needed, including near-infrared spectroscopy. (Spumy Pavel, et al; "Atmospheric Behavior and Extreme Beginning Heights of the Thirteen Brightest Photographic Leonid Meteors...," Meteoritics and Planetary Science, 35:243, 2000. Cr. R. Spaulding) Comment. As in SF#125, we must add that sounds are sometimes heard emanating from these anomalously high meteors, even though there is no air in which sound can he propagated.
