Astronomers, it seems, prefer different scenarios. C. Chyba and C. Sagan, in a major review article in Nature, see a two-fold problem: (1 ) identifying the source of the raw materials; and (2 ) identifying the source(s ) of energy required for the synthesis of complex organic chemicals. First, they point to the steady drizzle of tiny, organic-rich particles drifting down to earth from cometary debris. These particles, which even carry spacesynthesized amino acids down to the earth's surface, seem likely chemical precursors of life. However, the atmosphere is also a potential source of prebiotic chemicals -- providing energy sources are available. Chyba and Sagan suggest as sources: lightning, ultraviolet radiation, and the shock energy derived from meteorite/asteroid/comet impacts. Together these energy sources, especially ultraviolet light, might synthesize thousands of tons of complex organic compounds each year.

Such have been spotted on the moon, and it is unlikely the earth escaped such bar rages. Of course, older terrestrial craters are harder to identify due to the ceaseless geological activity here on earth. In the first 1996 number of Geophysical Research Letters, M.R . Rampino and T. Volk describe a possible swath of meteoric devastation across the North American Midwest. "Eight circular geologic structures ranging from about 3 to 17 km in diameter, showing evidence of outwarddirected deformation and intensive brecciation, lie within a linear swath stretching about 700 km across the United States from southern Illinois through Missouri to eastern Kansas. Based on their similar geological characteristics and the presence of diagnostic and/or probable evidence of shock, these structures, once classified as 'crypto volcanic' or 'cryptoexplosion' structures, are more confidently ascribed to hypervelocity impact. No other similar occurrence of aligned features is known, and we calculate the probability of a chance alignment to be less than 10- 9 ." The craters are all roughly the same age: 310-330 million years. Rampino and Volk suspect they were formed all at once by a string of asteroids or comets.

At present, over 120 hotspots are recognized by geophysicists -- and they are not distributed randomly about the globe. In fact, many seem to be diametrically opposite one another, as described by M.R . Rampino: "The observed number of antipodal hotspot pairs depends on the maximum allowable deviation from exact antipodality, At a maximum deviation of 700 km, 26% to 37% of hotspots form antipodal pairs in the published lists examined here, significantly more than would be expected from the general hotspot distribution. Two possible mechanisms that might create such a distribution include: (1 ) symmetry in the generation of mantle plumes; and (2 ) melting related to antipodal focusing of seismic energy from large-body impacts."

P.J . Boston et al have investigated one possible Martian ecosystem: "We have reexamined the question of extant microbial life on Mars in light of the most recent information about the planet and recently discovered nonphotosynthetic ecosystems on Earth -- deep sea hydrothermal vent communities and deep subsurface aquifer communities. On Mars, protected subsurface niches associated with hydrothermal activity could have continued to support life even after surface conditions became inhospitable.

The Copernican Principle, in particular, leads to all sorts of profound prophecies. The Copernican Primciple states that the earth does not occupy a special place in the cosmos. To this we add Darwinism, which asserts that, in the realm of biology, human origin is not special either; i.e ., we enjoy no special place among life forms. Building upon these two general "beliefs," J.R . Gott, III, proceeds to estimate the longevities of various observables, such as the lifetime of a particular species. What follows is a long, highly technical computation of various probabilities, such as the evolution of intelligent life in the universe. All this (and there is a lot of it) leads to the following: "Making only the assumption that you are a random intelligent observer, limits for the total longevity of our species of 0.2 million to 8 million years can be derived at the 95% confidence level. Further consideration indicates that we are unlikely to colonize the Galaxy, and that we are likely to have a higher population than the median for intelligent species." Why won't we colonize the Galaxy? Not because we are not able to, Gott says, but because " ...

But now, Russian scientist A. Sher and two colleagues claim that a dwarf version of the wooly mammoth survived on Wrangel Island, 120 miles off the Siberian coast until about 3,700 years ago. The Wrangel Island dwarf mammoths stood only about 2 meters high and weighed 2 tons. The British mammoth expert, A. Lister, said he was not really surprised at this discovery, because many islands supported dwarf versions of mainland animals during the Ice Ages. (Crenson, Matt; "A Mammoth Discovery," Dallas Morning News, p. 22A, March 25, 1993. Cr. L. Anderson. Also: Bower, B.; "' Dwarf' Mammoths Outlived Last Ice Age," Science News, 143:197, 1993.)

A burnt bone and a geometrical structure certainly suggest the work of an intelligent creature, as does the site's great distance from the surface. Torches would have been a necessity that far in. That 47,600-year figure, though, presents a problem. The first Cro-Magnons didn't filter into western Europe until about 35,000 BP. According to the accepted anthropological schedule, only those subhuman Neandertals inhabited that part of France in 47,600 BP. So, we must conclude that the Neandertals knew well the sophisticated use of fire. They also had enough curiosity to venture deep into the earth, where for some unknown purpose they piled together an enigmatic structure. All this also seems to require more information transfer than possible with a few "ughs"! (Balter, Michael; "Cave Structure Boosts Neandertal Image," Science, 271:449, 1996) There is always the possibility that those mysterious Cro-Magnons, who seem to have appeared out of nowhere, got to western Europe ahead of schedule. They are probably the artists who made those 31,000-year-old cave paintings at Grotte Chauvet in southern France. Even though of slighter build and smaller brains, the Cro-Magnons are thought to have quickly replaced the Neandertals. Complicating the picture is abundant fossil evidence of so-called "archaic" Homo sapiens in Europe commencing some 500, ...

Even so, careful searches with ground-based telescopes found nothing visible in the direction of the burst. Scientist B. Dingus remarked: "It's clear that it is unique event that liberates more energy in a few seconds than any other process in the Universe." Gamma-ray bursts remain one of the outstanding mysteries of astronomy. The depth of the mystery is underscored by the belief that the gamma rays must be confined to a narrow beam by their sources, rather than being emitted in all directions. No one knows how this focussing might be accomplished. Also, since we detect only those bursts that happen to be aimed at the earth (at a rate of about one per day), there should be a colossal number of bursts that we are unaware of.

Now, an exchange of letters in a creationist journal gives us the opportunity to present a few facts about a giant bone bed of terrestrial vertebrate fossils: the Karoo Supergroup of southern Africa. The point being discussed by the creationists is the source of the estimated 800 billion vertebrate fossils contain ed in the Karoo deposits. Whence this astronomical number of mainly swampdwelling reptiles? And whence the immense volume of sandstones and shale that contains their bones? The Genesis Flood model favored by creationists requires that all 800 billion animals be drowned at the same time and swept into South Africa and fossilized. But, they ask themselves, could the entire earth ever have supported so many swamploving reptiles at the same time? Is the Flood model threatened?

The same report mentions extensive underground rivers, but it has taken over 2300 years and the development of statistical methods to suggest a connection among fluid pressure, earthquakes, and geophysical luminosities. Many of the sightings are treated as mystical experiences, depending on local cultural values. In Denver and Rangely, Colorado, and Attica, New York, these sightings correlate with earthquakes and injection of fluid into the earth for waste disposal or secondary oil recovery. In the New Madrid, Missouri, area, luminosities are highly correlated with flooding on the Mississippi River and tend to occur 9 months after high water. Enough luminosities, and radio emissions in the ULF band, are observed weeks to months before earthquakes to suggest that they be tested as a possible forecasting tool for the select places where they occur. The pattern of occurrence may delineate the progress of tectonic strain and so indicate the direction or even location of a future epicenter. Fluid moving through developing cracks may be the source of electrical energy which powers the EQL. A number of potential mechanisms should be considered, involving tectonic strain, exoelectron emission, streaming potential, EM excitation of water droplets, and the fault zone as an EM waveguide."

Day presented a paper that: Itemized the many important ways n which Mars differs from the other inner planets and moons; Proposed a mechanism that might lave created these stark differences; and Identified the earth as the most likely perpetrator of this celestial catastrophism. Day's abstract follows: Mars has surface features that are not seen on inner planets or moons. These are hemispheric asymmetries, idiosyncratic surface fracturing, localized vulcanism, altitude differences, chains of pits, and the nature of dry river-like channels. Other features include extensive loss of an early atmosphere and liquid water. There is interest in the lower-altitude northern region, with its surface formed after the period of heavy bombardment, as a possible ocean basin. The evidence for this is very sparse: no river deltas, no river networks, little debris at the ends of the catastrophic flow channels. The surface is consistent with the stripping anticipated by a Roche-limit encounter. The low-density Martian moons appear to be unconsolidated material of higher density; they appear to be from low-gravity aggregation of that part of the Martian debris that went into orbit as a short-lived ring. A Roche-limit encounter is invoked as a reasonable hypothesis to explain these features. Earth, Mars' nearest planetary neighbor, may have ...

New finds of tektites have expanded the strewn field of these Australasian tektites to include part of China. It now appears that about 30% of the earth's area was subjected to this stony bombardment. It is inescapable that the Australasian-tektite fall was a major event in the earth's history. But where are other signs of this great catastrophe? The present consensus holds that the Australasian tektites originated when a large celestial body slammed into our planet somewhere in Southeast Asia. The energy of the impact splashed droplets of molten rock into the atmosphere, where they were shaped aerodynamically and then fell as tektites. The extent of the immense Australasian-tektite strewn field implies a hard-to-miss crater about 100 kilometers in diameter. Yet, despite the geological recency of the event and despite much geological surveying, no convincing crater has been discovered. (SF#115) So, we have abundant evidence of a terrestrial event encompassing much of the planet but no "smoking crater"! The mystery deepens when one realizes that whatever cataclysm sent the Australian tektites aloft may have been comparable in magnitude to the impact that extinguished the dinosaurs (and other fauna) some 65 million years ...

Using rock samples brought up from submerged Pacific sea-mounts, they find that the earth's magnetic poles shifted 15-20-deg about 84 million years ago. The north magnetic pole was not slowly drifting, it was lurching. It took just a couple million years to shift 700 miles or more; that's more than ten times the rate of continental drift. The earth from afar must have seemed to be a disturbed top---on a geological time scale, of course! What could have perturbed the earth? One suggestion blames a sudden shifting of the planet's mass distribution, some sort of subterranean indigestion, like a subducted ocean plate suddenly plunging through into the lower mantle. (Kerr, Richard A.; "Did the Dinosaurs Live on a Topsy-Turvy Earth?" Science, 287:406, 2000.) The biological consequences of such a sudden tilting could have been severe. The event -- known as rapid true polar wander -- may have been accompanied by worldwide volcanic upheavals and reorganization of tectonic plates that would have played havoc with anything living in the Late Cretaceous period, 65 million to 99 million years ago.

Their trace impurities are believed to accurately record the earth's climate over the last several hundred thousand years. The temporal accuracy of this record is based upon the assumption that these impurities have not migrated vertically from where they were deposited. This assumption is now under severe stress with the discovery of anomalous diffusion within ice plus a phase phenomenon called "premelting," both of which result in the transport of the climate-marking impurities far from their original layer of deposition.

The smaller ones are completely consumed. A few bigger ones reach earth and are renamed "meteorites." So far, all of this is well-understood. But when meteors begin to burn up much above 100 kilometers, a problem arises. The air there is normally much too thin to cause incandescence and burn-up. Observational anomalies are abundant. Two Leonid fireballs were seen glowing at 160 kilometers by Japanese scientists. In 1998, a Dutch team in China detected bright Leonids at 200 kilometers! In addition, some Russian reentering space-craft began glowing well above 100 kilometers. ANAL is a solid phenomenon. Of course, the density of the upper atmosphere does increase somewhat when solar activity is high. Atmospheric gravity waves can also cause the atmosphere to bulge out. But these effects are inadequate to explain all observations. R. Spalding, at Sandia National Laboratories, ventures that ions in the upper atmosphere are electrostatically attracted to meteors and create light when they collide with them. A. Ol'khovatov suggests that "plasma instabilities" may be involved.

According to this scenario, once the shock of the asteroid impact released the methane from its icy prison, it rose to the surface of the oceans in a world-wide burp. Methane, unfortunately for the dinosaurs and many other life forms, is highly flammable. Lightning could have ignited it almost immediately if it was concentrated enough. A colossal firestorm might have then enveloped the entire planet. The whole atmosphere could have been afire. This, according to B. Hurdle and colleagues at the Naval Research Laboratory, who speculate that the dinosaur hegemony may ended suddenly in flames rather than in a long, drawn-out whimper.

Ten million years after the dinosaurs may have roasted in a global firestorm, another methane burp may have erupted from the oceans. This burp was slower and did not ignite but was just as lethal. It filled with atmosphere with a highly effective green-house: methane. The result was a pulse of global warming; as seen in a 5-7 -deg C increase in the temperature of ocean-bottom water during that period. Biological evidence for the event occurs in the skeletons of marine animals that litter the ocean sediments laid down in that lethal period.

The other two could be volcanic say the skeptics. It will take an expedition to Chad to clarify things. (Kerr, Richard A.; "Impact Craters All in a Row?" Science, 272:33, 1996) A final comment -- at last! All impactcrater chains are relevant to the claim of H.R . Shaw that even the earth's largest impact structures are found in swathes (chains). In his wonderfully heretical book Craters, Cosmos, and Chronicles: A New Theory of the Earth, Shaw mentions several such swathes. One of his chains includes Chicxulub (beneath Yucatan), Manson (Iowa), Avak (Alaska), and three more in Russia.

In the five years that have transpired, Galileo has radioed back voluminous data about Jupiter itself and its four large Calilean satellites. 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. Europa probably possesses an ocean, and Callisto might also. Only one of Jupiter's large satellites, Ganymede, boasts a magnetic field. In fact, Ganymede is apparently the only satellite in the solar system to display an intrinsic, dipole magnetic field like the earth's . Although Ganymere's magnetic field is like that produced by a permanent bar magnet, its core is much too hot for permanent magnetism. Again like the earth, Ganymede's field is theorized to be generated by the convection of electrically conducting liquid in its core -- a dynamo of sorts. 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.

Science Frontiers ONLINE No. 134: MAR-APR 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Missing Planets In Globular Clusters If you lived on a planet circling a star in a globular cluster, you would see a night sky ablaze with thousands of stars all brighter than the brightest in the earth's sky. This is because globular clusters contain tens of thousands of stars all compressed into 5-25 parsecs -- they are much more tightly packed than those in the Milky Way in general. In fact, though, you would have to observe this blazing sky from a spaceship, because diligent searches have not detected any planets in any of the many globular clusters. In 1999, a team of 24 astronomers used the Hubble Space Telescope to search for planets in the cluster named 47 Tucanae. Their method was to look for dark planets crossing the bright disks of the cluster's stars. After patiently watching 34,000 stars, they came up empty-handed. For some unknown reason, planets never formed around the stars in 47 Tucanae -- or in any other globular clusters checked so far. Are globular clusters in general different from the rest of the Milky Way? Possibly, see below. (Anonymous; "No Globular Planets?" Astronomy, 28:34, October 2000. Anonymous; "Planets Come Up Missing in a Globular Cluster," Sky & Telescope, 104:23, October 2000.) Answer. Globular clusters are peculiar in several additional ways. For example, the ...
