Flood legends, geomagnetic reversals, tektites, paleoclimatology, salinity crises, and other familiar standbys of the catastrophists force P.

He shows that the earth rotates slowly and that, even with the stabilizing equatorial bulge, our planet is rather sensitive to outside forces. It is, he says, like a tippe top or magic top; a 8,000-mile-diameter top that turns over repeatedly in response to external influences.

There is no such obvious explanation for radio propagation problems during lunar eclipses. Nevertheless, we have the following observation by L.M . Nash: "During 1978/79, I was stationed on Diego Garcia (U .S . Naval base in the Indian Ocean). I was an amateur radio operator then, and one night there was a total (or near total) eclipse of the moon. I was in contact with a station in Utah, on the 15 meter (21.0 to 21.45 MHz) band. When the eclipse started, the Utah station faded out, and all I heard was a sizzling, crackling noise across the entire 15-meter band. This started and ceased within the duration of the eclipse. I then reestablished contact with the Utah station, who was still on the same frequency talking to a friend of his. When I asked him what happened, he stated that my signal had just disappeard."

Normal galaxies seem to have masses of about 1011 times that of the sun. The unthinkable assumption suggests that every 108 years or so, these ordinary, unassuming galaxies become supermassive (about 1013 solar masses) for several million years. When the core of a galaxy becomes supermassive, its stars are tugged into tight new orbits. The subsequent switching off of the supermass allows the galaxy to expand outwards again. The author claims to have found just such expansion effects among the globular clusters in our own galaxy. His data are striking and quite convincing. The notorious "missing mass" problem of cosmology disappears with the cyclic supermass assumption because the time-averaged mass of each galaxy will be much higher than that observed in its normal enervated state. Doesn't this sudden temporary appearance of mass violate the laws of physics? No, says the author, physicists habitually assume a superfluid, superconducting vacuum state, which is the ultimate source of all mass-energy, when they develop their theories of fundamental particles. If particle physicists can (and must) evoke such magic, so can astronomers. (Clube, Victor; "Do We Need a Revolution in ...

Monarch butterflies, however, are mere insects, with tiny brains (navigation-data processors) and not much in the way of the environment sensors and internal clocks required for long-distance migration. Yet, some of these colorful insects manage to flutter up to 4,000 kilometers from the eastern U.S . and Canada to their wintering grounds in Mexico. How do they do this? S.M . Perez et al have now shown that monarch butterflies are equipped with a sun compass; that is, they chart their courses by noting the sun's changing azimuth. This feat requires not only the measurement of solar azimuth but also reference to an internal clock. Humans cannot do this without artificial instruments. Furthermore, even on cloudy days, migrating monarchs fly in the proper direction (generally south-southwest). Apparently, they also have evolved a backup navigation system, perhaps a geomagnetic compass. (Perez, Sandra M., et al' "A Sun Compass in Monarch Butterflies," Nature, 387:29, 1997.) Comment.

Be that as it may, there is something puzzling about the northern plains. We now have information from the Mars Global Surveyor (MGS), now orbitting the red planet, that the low-lying northern plains are much flatter than thought. For thousands of kilometers, they are smooth on a scale of hundreds of meters. This is flatter than the lava flows of the lunar maria; flatter than the smoothest central Sahara. These startling data come from the MGS's laser altimeter that can measure elevation of the terrain below it with 10meter accuracy averaged over the beam width of 150 meters. The only known terrain in the entire solar system that can match this flatness is the abyssal, sediment-filled floor of the South Atlantic. Hmmm! Does this imply that the northern plains of Mars were once an ocean floor? That's the favorite interpretation today.

Frank and J.B . Sigwarth that the earth is bombarded daily by 30,000 house-size icy comets. If such bombardment has really been occurring, scientists would have to rethink the origins of the earth's oceans, terrestrial life, and the formation of the solar system. No wonder the icy-comet hypothesis is strongly challenged! Three of the more interesting points made by this group of papers are as follows: Our moon could not escape the icy-comet bombardment. Roughly 1,000 craters 50 meters in diameter and splashes of debris 150 meters in diameter must occur each. There is no evidence that the moon is thus afflicted. Comets also carry the noble gases argon, krypton, and xenon. These gases should accumulate in the atmosphere as the comets disintegrate. The amounts of these gases actually measured are 10,000 times less than those the postulated bombardment would produce. The icy comets should break up near the earth and produce clouds of ice crystals. Sunlight reflected from such 30-ton clouds would be brighter than Venus and easily visible before they disperse. Such objects are rarely seen, implying that small icy comets do not exist in the numbers claimed. Preceding this series of five ...

Even if the patient observer is rewarded by a green flash, he may really have been deceived, for there are "false" green flashes. A. Young, San Diego State University, reported at a recent meeting of the American Astronomical Society on a peculiar type of optical illusion that can afflict observers of the setting sun. It seems that the intense red light of the sun near the horizon can bleach the red-sensitive receptors in the retina so that an intent observer becomes temporarily color blind to red. When this happens, the observer sees the yellow part of the dispersed solar spectrum as being green (yellow minus red = green). The true green flash may never have appeared at all.

The successes of this model have been tempered by the fact that it also implies that Saturn's rings are very young. "Theorists would have no problem with a broad, featureless disk surviving the 4.5 billion years since the early days of the solar system, but features such as spiral density waves are clear evidence that satellites, including the profusion of small ones found near the rings, are draining angular momentum from the rings.

The bands are initially faint and jumbled; but as totality approaches, they become more organized, their spacing decreases to a few centimeters, and their visibility improves. After totality ends the bands can reappear and become progressively fainter and more disorganized until they disappear. "Shadow bands seem to move perpendicularly to their length, but this is only an illusion. It stems from a lack of features that allow the eye to track motion along the length of the bands." Codona explains the shadow bands as basically a twinkling effect involving the thin solar crescent just before and after totality. The twinkling is created by turbulence only tens or hundreds of feet above the ground. The eclipse shadow bands, like so many other "well-explained" phenomena, display idiosyncracies that do not dovetail well with theory.

This string exists only in closed loops of infinite strands. Such string in loop form could have seeded galaxies and even black holes of solar mass. But these are not the major reasons why astronomers like the string hypothesis.

These natural satellites have turned out to be a disparate bunch. Three have iron cores, but Callisto breaks the mold with an unusual core of mixed ice and rock.

Although Ganymere's magnetic field is like that produced by a permanent bar magnet, its core is much too hot for permanent magnetism.

All well and good, but Ganymede is so small that it should have cooled off billions of years ago thereby freezing its metallic core. So then, whence its magnetic field? One way out of this box it to suppose that about a billion years ago Ganymede was circling Jupiter in an orbit that took it much closer to this ponderous planet. Then, Jupiter's powerful gravitational field would have gently ...

The other Big-Bang basher featured in Scientific American is H. Alfven, a Nobel-Prize winner in physics. Alfven postulates a universe dominated by electromagnetic forces, which he believes to be more important in shaping the cosmos than gravitation. His electromagnetic theory disallows any universe smaller than 1/10 the diameter of our present universe, thus excluding the Big Bang's point origin. Electromagnetic forces can account for all types of galaxies without resorting to the infamous "missing mass." Alfven can even account for the cosmic microwave background. Furthermore, Alfven's theories are supported by observations of solar-system plasma and magnetic fields. NASA's T.E .

Purrington's reconstruction of sight lines along the avenues, using his assumed center, does not support the idea that the avenues were solstice markers. Brecher and Haag responded in the second paper that their viewing center is 100 meters from Purrington's . With this change. they claim good fits for two of the avenues as solstice markers. One of the two remaining avenues turn out to mark the setting of Canopus, the second brighest star in the sky. Even the unassigned last avenue has astronomical significance; it marks the setting of Gamma Draconis, a second-magnitude star, which the ancients employed as a nocturnal hour hand as it swung around the pole star.

Somehow, the rotating magnetic field interacts with the particles making up the rings, forcing density or reflectivity changes that we see as transitory spokes. It is not yet clear how this magnetic tune is played. (Proco, C.C ., and Danielson, G.E .; "The Periodic Variation of Spokes in Saturn's Rings," Eos, 63:156, 1982.) Comment.

Slabinski of the Communications Satellite Corporation claims that there are three separate errors in P. Warlow's theoretical analysis of terrestrial pole-flipping due to the gravitational torques created by a passing celestial body. With these errors corrected, the earth is 200 times less sensitive to pole-flipping. Slabinski does not believe that any known solar system object could turn the earth end-for-end if it passed by. This item proclaims that the discovery of Warlow's errors is a serious blow to Velikovskian catastrophism. (Anonymous; "Fatal Flaw in Pole-Flipping Theory," New Scientist, 92:433, 1981.) Comment. We shall now wait for a rebuttal by Warlow and/or the Velikovskians. The flipping torques depend, of course, upon the mass and distance of the perturbing body. Whatever the outcome, the reality of astronomical and terrestrial catastrophism depends upon terrestrial geology, the testimony of history and myth, and other sources. Update. Over a decade has passed and no rebuttal by Warlow has been seen. We must, therefore, consider his hypothesis highly questionable. From Science Frontiers #19, JAN-FEB 1982 . 1982-2000 William R.

Science Frontiers ONLINE No. 19: Jan-Feb 1982 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Rims Of Galaxies Spin Too Fast According to the physical laws governing orbital motion in a central force field, like that of our sun, distant objects should rotate more slowly than those closer to the central mass. Thus, the outer planets of the solar system swing around the sun more slowly than the earth and the other inner planets. Astronomers always expected that the stars rotating around the massive hubs of the galaxies would obey these laws in a like manner. No such luck! Doppler measurements of galaxy rotations made by Vera C. Rubin and her colleagues, at the Carnegie Institution, indicate that most stars out near the galactic rims rotate just as fast or faster than those closer to the hub. Astronomers suppose that this anomalous rotation may be due to halos of undetected burntout stars and/or gas fringing the galaxies. Such halos would dis-tort the inverse-square-law field, permitting the observed anomalous rotation. (Anonymous; "Fast-Spinning Galaxies," Science Digest, 89:18, November 1981.) Comment. No one has yet discovered these hypothetical halos of mass. The universe seems to be full of "missing mass." An unpopular alternative would be the admission that Newton's Law of Gravitation does not hold on the galactic scale. From Science Frontiers #19, JAN-FEB 1982 . 1982-2000 William R. Corliss ...

These magnetic perturbations resembled those following nuclear atmospheric explosions. The Tunguska object left no smoky trail like many fireballs, but rather irridescent bands that looked like a rainbow. Following the "explosion," at least part of the object continued on in the same direction but veered upwards. [Meteors sometimes skip out of the atmosphere on trajectories like this.] Although the Tunguska event occurred on June 30, 1908, optical anomalies appeared all across northern Europe as early as June 23. These included mesospheric, silvery clouds, very bright nights, colorful twilight afterglows [something like those following the Krakatoa eruption], and remarkably intense and long-lasting solar halos. Some of these effects persisted until late July. Neither craters nor meteoric debris have been discovered so far, despite assiduous searches. The explosion created a shock wave that leveled 2150 km2 of taiga and a flash that singed about 200 km2.
