Once again, comets seem to be the culprits. C.F . Chyba has examined the lunar impact record and derived an estimate of the total mass of objects impacting the moon during the (hypothetical) period of heavy bombardment 3.8 to 4.5 billion years ago. This allowed him to calculate the mass influx for the earth during this period. His conclusion: if only about 10% of the incoming mass consisted of comets (mostly ice), the earth would have acquired all its ocean water. (Chyba, Christopher F.; "The Cometary Contribution to the Oceans of Primitive Earth," Nature, 330:632, 1987.) Comment. Frank claims that the earth today is continually bombarded by small icy comets, which down the eons may have kept the ocean basins full. So, we have two possible extraterrestrial sources of oceans -- both of a cometary nature. It was only yesterday that the idea of ice surviving in outer space was ridiculed; no one even dreamed that our oceans could be composed of space ice!

A strong consensus has these small, drop like glassy bodies originating when meteors smash into the earth, liquifying themselves and some of the surface rocks. The resulting liquid droplets solidify in flight and when they descend form "strewn fields" hundreds, even thousands, of miles in extent. The main argument has been over whether the actual impact craters giving rise to the tektites might actually be on the moon instead of the earth. Looking over the literature, one sees that this debate has been characterized by much invective and scientific infighting. Today, most scientists concur that some tektite strewn fields are definitely associated with specific, although distant, meteor craters on the earth's surface. Unfortunately, the large separations of craters and strewn fields add a circumstantial flavor to the evidence. However, some tektite-like objects are to be found in the immediate vicinities of terrestrial craters, but not in far-flung strewn fields; viz., the Aouelloul Crater in Mauritania, and the Zhamashin Crater in the USSR. Another example has now come to light: the Lonar Lake Crater, a 50,000-year-old impact crater, in the Deccan flood basalts in India.

... Martian water disappeared 2 billion years earlier? One line of thought maintains that "fluvial" does not mean "pluvial," and that Martian water has come from below rather than as rain from the atmosphere. Both fluvial episodes, in this view, occurred when something caused the Martian crust to release huge quantities of stored water. Hydrothermal activity is mentioned as a possibility. (Eberhart, J.; "The Martian Atmosphere: Old Versus New," Science News, 135:21, 1989.) Comment. Another speculation is that immense quantities of Martian water are tied up in methane hydrate and is released when the ambient temperature is somehow increased or perhaps by seismic activity.

Diffusionists seize upon all manner of artifacts to prove that peoples of the various continents made frequent contacts among themselves long before the European exploration of the planet. In the latest issue of Archaeoastronomy (dated 1984 but published in 1986), C.R . Wicke analyzed the rabbit-in-themoon motif. "Representations of a hare or rabbit on the moon are found in the art of ancient China and in Pre-Columbian Mexico. Mythologies of both areas also place a rabbit on the moon.

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.

A third discontinuous ring seems to be indicated by the reanalysis of some 1968 occultation data. Astronomer Bill Hibbard, at the University of Arizona, speculates that the three separate arcs of material orbiting Neptune are "trying to decide whether to become a satellite."

First, at least within certain large classes of lunar craters, internal origin (i .e ., some form of volcanism) predominates over impact; this result raises questions about the reality of the 'era of violent bombardment.'Second, the origin of tektites by meteoric impact on the earth cannot be reconciled with physical principles and is to be abandoned. The only viable alternative is origin by lunar volcanism, which implies the following: continuance of (rare) explosive lunar volcanism to the present time; existence of silicic lunar volcanism and of small patches of silicic rock at the lunar surface; a body of rock in the lunar interior, probably at great depth, which is closely similar to the earth's mantle and which contains billions of tons of volatiles, probably including hydrogen; and the origin of the moon from the earth after the formation of the earth's core."

... based astronomers watch for occultations or dimmings of stars as they pass behind the rings. This seems straightforward enough in theory, but the occultations have been perplexing in practice. First, one member of a closely spaced double star will be occulted normally by the rings but its companion won't . Second, some terrestrial observatories will record an occultation but another a few thousand miles away will not. Such experiences have led to the hypothesis that the rings are discontinuous; that is, they are arcs rather than complete rings. Why should Neptune's rings be different from those of the other major planets? On speculation maintains that the arcs are the consequence of one or more recently satellites. Another hypothesis, by J.J . Lissauer, has the arcs gravitationally shaped and maintained by two moons, one of the shepherd type (as with Saturn's rings), the other at a Lagrangian point in the arc's orbit. (Kerr, Richard A.; "Neptune's Ring Arcs Confirmed," Science, 230:1150, 1985. Also: Lissauer, Jack J.; "Shepherding Model for Neptune's Arc Ring," Nature, 318:544, 1985.) Comment.

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.

Cole thinks that astronomers might have more success in explaining the origin of the solar system if they considered it a system of five large bodies of star stuff (light elements), each surrounded by its own retinue of high density satellites (the sun's four satellites would be the inner planets). In effect, then, we would have a quintuple star system in which only one member (the sun) collected enough star stuff to make it to incandescence. The four, large, outer planets would be merely failed stars. The advantages of this change of perspective are threefold: (1 ) All five central bodies are now compositionally similar as a class, (2 ) In each of the five systems, the angular momentum of the central body is greater than that of its satellites, whereas in the unitary solar system the angular momentum of the nine planets is much greater than that of the sun -- an embarrassing anomaly.

(Here, "fresh" means post-mare formation.) Such an origin would seem to favor random distribution of these craters. "However, it appears that the distribution of these large, fresh craters is far from random, contrary to what would be expected if their mechanism of formation was by impact. Even the most casual observer of the Moon cannot help but note that the maria contain very few large craters. The more experienced observer will take note of several apparent anomalies. Six magnificent post-mare craters are almost fortuitously located immediately adjacent to mare regions, these being Langrenus, Theophilus, Cavelerius, Aristoteles, Aristarchus, and Copernicus" The author of these observations then buttresses them with a statistical analysis, which indicates a strong, nonrandom distribution of all of these fresh craters. Apparently, the volcano-meteorite controversy is not completely settled after all these years. (Kitt, Michael T,; "Anomalous Distribution of Large, Fresh Lunar Craters," Strolling Astronomer, 31:22, 1985.) Comment.

Yet, there is no agreement as to its mode of origin. One might say that planetary scientists have just about thrown in the towel on the three major theories of lunar origin. Two recent articles attest to this discouraging situation. A Sky and Telescope article provides an excellent review of all three theories, indicating the reasons why each fails to convince a majority of scientists. The theories and the primary reasons for their rejection are: (1 ) Fission from earth . Lack of sufficient angular momentum in the earthmoon system and the fact that the moon does not orbit in the plane of the earth's equator. (2 ) Gravitational capture . The capture of such a large object in a nearly circular orbit is considered too improbable. (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?"

Anorthosite is also present -- a type of rock found on the earth and moon but not ordinary meteorites. The implication is that ALHA 81005 was blasted off the moon by a comet or big meteorite.

One hypothetical scenario has the primitive moon surrounded by many moonlets 60 miles and larger in diameter, plying equatorial orbits that are unstable. As the moonlets' orbits decayed, some crashed into the moon's equatorial regions, blasting out a band of huge craters. The force of the impacts also caused the lunar crust to slide over the still-liquid core by as much as 90 . When the next group of moonlets crashed, they gouged out a new belt of craters and shifted the crust still more. Magnetic measurements of lunar rocks tend to confirm that the lunar crust did indeed shift by large angles -- several times. (Anonymous; "Did the Moon Have Moonlets?"

Dodwell has analyzed the observational records com-piled for the many gnomons erected all over the civilized world during the past 4,000 years. Gnomons are vertical markers that cast shadows from which the local latitudes can be computed. (All one needs are the measurements of the shadow lengths on the longest and shortest days of the year.) The earth's tilt or obliquity-of-the-ecliptic may also be calculated from gnomon data -- and therein lies the anomaly. The tilt of the earth's axis is supposed to vary cyclically between 22 and 24.5 over a period of some 40,000 years due to the pulls of the moon, the sun, and the planets on the earth's equatorial bulge... Tilt angles computed from ancient gnomon observations deviate markedly from the theoretical curve.

In addition, there are unexplained perturbations in the orbits of earth satellites, peculiar periodicities in the sunspot cycle, and equally puzzling regularities in earthquake frequency. Infrared detectors have also picked up unidentified objects in the sky. These anomalies might all be explained by the existence of a large, dark planet with several moons -- or, if the mystery object turns out to be very far away, by a very large, dark stellar companion of our sun with its own system of planets.

... Science Frontiers ONLINE No. 9: Winter 1979 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Moon-like craters in the north sea floor During the exploitation of the North Sea oil fields, geophysicists made detailed surveys of sea-floor topography with seismic instruments called boomers. They were startled to discover thousands of elliptical craters or pockmarks in the sediments. The craters are 30-330 feet across, 6-25 feet deep, and located in water about 500 feet deep. The long axes of the craters point roughly in the same direction; and the craters tend to be arranged in lines. The authors suggest that escaping subsurface gases and fluids may have formed the unusual structures. The possibility was underscored on July 30, 1978, when a very large eruption of sediment was detected by sonar. (McQuillin, Robert, and Fannin, Nigel; "Explaining the North Sea's Lunar Floor," New Scientist, 83:90, 1979.) Comment. The North Sea is a prime habitat of mistpouffers (sea-associated booming sounds). There might be a correlation here between natural-gas eruptions and these strange booming sounds. Also, the crude similarity of these sea-floor craters to the Carolina Bays should not be passed over. Reference. All types of unusual craters are cataloged in Section ETC in: Carolina Bays, Mima Mounds. For ordering information, visit: here . From Science Frontiers #9 , Winter 1979 . 1979-2000 William R.
