This cataclysmic event is also blamed (by some, at least) for the apparent sudden biological extinctions recorded on these pages of the fossil record. In this setting, the authors of this paper calculate the effects on the earth of a 10-kilometer-diameter object impacting at about 20/km/sec. Do the theoretical results jibe with the geological and paleontological data? Very definitely. Crater ejecta rich in extraterrestrial material would be blasted to an altitude of 10 km, where winds would insure global distribution. In terms of biological stress, the 10-km projectile would transfer 40-50% of its kinetic energy to the atmosphere, creating a heat pulse that could raise global temperatures 30 C (50 F) for several days. Many large animals might well succumb to such a temperature transient. In addition, the protective ozone layer might be blown away by shock waves and not reform for a decade.

John P. Bagby has studied this problem for over 20 years, publishing several hotly debated papers during this period. His latest contribution summarizes evidence supporting his contention that the earth has captured chunks of space debris, some of which have disintegrated, some of which are still in orbit amidst tons of artificial-satellite debris. The supporting observations have come from optical surveillance programs, tracking networks, radio-propagation anomalies, and (most interesting to the anomaly collector) old reports of bright objects near the sun (especially the August 1921 object) and the curious group of retrograde objects that passed over Germany in 1880.

Mainstream geologists write these sandhills off as eolian (wind-carried) deposits laid down during the late Pleistocene. Hansen, however, along with geological iconoclast A. Kelly, demur. The Nebraska sanhills, they aver, were actually deposited by a wall of water sweeping down across the continent from the north -- very likely the consequence of an impact of a large asteroid.

Until astronomical catastrophism became more fashionable in recent years, the so-called "dust-veil" event of 536 AD was blamed on a huge volcanic eruption. Work by M.G .L . Baillie now casts doubt upon interpretation. "Now tree-ring data, published by Professor Mike Baillie of Queens University of Belfast, has brought catastrophes almost into modern times. The tree rings show that in the mid 530s -- just about the time civilisation on Earth suffered a sharp setback -- there was a sudden decline in the rate of tree growth which lasted about 15 years. Clearly, something dramatic had happened. "There are two possibilities: a huge volcanic eruption or a collision between the Earth and a solid object: an asteroid or comet. Ice-cores drilled from Greenland show no evidence of large-scale volcanic activity at that time, so Professor Baillie and others now believe a cosmic impact is more likely. The result would have been to throw up a huge veil of dust and debris, cooling the Earth and producing widespread crop failures." (Anonymous; "Raining Death and Dark Ages," London Times, July 27, 1994. Cr. A.

The terrestrial ages (times since arrival on earth) measure between 1,000 and 700,000 years, implying that the Antarctic ice sheet may be at least 700,000 years old. This is unfortunate for several proposed scenarios of recent catastrophism, which envision an iceless Antarctica. At least 20 amino acids appear in the more than 40 carbonaceous chondrites picked up with sterile equipment. These meteorites are dated as 4.5 billion years old, or 1 billion years older than the earliest terrestrial life found in the rocks.

Kerr reviews several recent studies of fossil bryozoans and snails. Some of these painstaking dissections of the fossil record were carried out by scientists initially committed to Darwinian gradualism. Even these researchers have been forced to acknowledge that much biological evolution proceeds not in minute steps but by large jumps or saltations. Such abrupt speciation is tough enough to explain, but even more daunting are those species untouched by change over millions, even hundreds of millions of years. Indeed, the major characteristic of the fossil record and, therefore, earth life as a whole, has been stasis rather than speciation, despite all manner of asteroid impacts and climatic traumas. Nevertheless, many biologists think that species are somehow frozen in time by environmental forces that keep them from straying from their little niches. This being so, paleontologist D. Jablonski, University of Chicago, asks: If stability is the rule, how do you get large-scale shifts in morphology? How do you get from funny little Mesozoic mammals to horses and whales?

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."

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).

He has gone so far as to say that our planet boasted rings on 16 separate occasions in the past 2800 years. "Kaare Rasmussen of the National Museum in Copenhagen carried out a survey of all reports of meteorite falls, fireballs and showers of shooting stars from 800 BC to 1750 AD. He then carried out a statistical analysis of the data. He discovered that there were many distinct periods of intense activity." Rasmussen found that the active periods, during which he believes a ring existed about the earth, began with a peak of high meteoritic activity as the ring formed, as a consequence of the earth's capture of a comet or asteroid. This was typically followed by a decrease of activity indicating ring stability. Finally, the ring broke up as its particles were decelerated by the earth's upper atmosphere, leading to another peak of activity. Thus, the plot of me-teorite activity is U-shaped, as in the figure, with the bottom of the U a bit higher than the normal background. (Gribbin, John; "Will the Earth's Rings Return?"

In the currently accepted theory of solar-system formation, all of the planets and their satellites condensed from a primordial disk of dust sur rounding the just-formed sun. The planets closer to the solar inferno lost more of their easily vaporized constituents due to the sun's heat. The cooler, outer planets were able to retain large amounts of ices. In this scenario, we would expect Mercury to be rich in iron and rocks. This seems to be the case, but it has too iron to fit the theory. Astronomers have tried to save the theory by supposing that a large asteroid sideswiped Mercury tearing off part of its outer layer of lighter rocks, leaving the heavier iron core untouched. The theory doesn't say what happened to the debris from this colossal collision. As for Mercury's magnetic field, it is small, only 1% that of the earth. But where does it originate? All of the other planets with magnetic fields (earth, Jupiter, Saturn, Neptune, and Uranus) rotate rapidly and are believed to have molten interiors, allowing fluid dynamos to form.

Such bacteria are today found in boreholes as deep as 500 meters, in thermal springs, and around deepsea vents.

It is not possible to tidally evolve into a synchronous rotation without passing through a chaotic zone. For irregularly shaped satellites this chaotic zone is attitude-unstable and chaotic tumbling ensues. This episode of chaotic tumbling probably lasts on the order of the tidal despinning timescale. For example, the Martian satellites Phobos and Deimos tumbled before they were captured into synchronous rotation for a time interval on the order of 10 million years and 100 million years, respectively.

There is no pattern, gamma-ray bursters seem to be evenly distributed in all directions. This is not what the astronomers expected, and the implications of this isotropy are staggering. Gamma-ray bursts emanate from highly localized unseen sources. They may last for a few milliseconds or stretch out for several minutes. The energy in the bursts ranges over 26 orders of magnitude. The rise-times of the bursts are so short that the sources can only be a few hundred kilometers across. Before the accompanying map appeared, most scientists thought that the bursters were nearby, probably in the disk of the galaxy, and were due to asteroids being digested by neutron stars or possibly neutron-star quakes. If such were so, the bursters would be concentrated in the plane of the galaxy (the Milky Way), which clearly they are not. Another theory places the bursters in a distant spherical halo about our galaxy. But, in this case, the bursters would have to be much more energetic than astronomers care to contemplate. In fact, if they exist in a galactic halo, we should also be able to detect the bursters in our neighboring galaxies -- but we do not!

They suggest that the body which collided with Earth 65 million years ago and left the telltale iridium residue may have been organic-rich, perhaps like a C-type asteroid or a comet. Such a possibility has interesting implications for the extinction and related atmospheric effects, and supports the idea that impact events could have supplied the Earth during a much earlier period with the raw materials for organic chemical evolution." Actually, the above quotation is pretty much in line with present mainstream thinking. Perhaps so, but Bada and Zhao identified two troubling anomalies.

But in Donnelly's day, all geologists were uniformitarians and wedded to glacial theory. Donnelly's "age of fire and gravel" was really a succession of Ice Ages. Quite a difference in mechanism! Glacial theory, however, has difficulty in explaining apparent glaciations during periods when the earth was supposed to be very warm. Nor does it account easily for glacial-like debris in equatorial regions. With the current ascendancy of "impact geology," some brave geologists are reinterpreting supposed glacial deposits in terms of sheets of ballistic ejecta from the impacts of comets and/or asteroids. Modern estimates of terrestrial cratering suggest that 10% of our planet's surface could be covered by 10+ meters of ejecta, and 2% by 200+ meters. Now that's a lot of ejecta! (Rampino, Michael R.; "Tillites, Diamictites, and Ballistic Ejecta of Large Impacts," Journal of Geology, 102:439, 1994.) Comment. The Ice Ages won't be melted completely away by such reinterpretations. Nor will I. Donnelly ever get any credit for his research and vision. But we are making progress.

... of Siberia. All consist mostly of basalt lava flows; those on continents include minor quantities of rhyolite, and variable amounts of sediment. All seem to have appeared suddenly, within plates. No consistent context of plate interactions explains them. We suggest that large lava plateaus are indeed terrestrial maria." Alt et al go on to show that these lava plateaus seem to have initiated continental rifts and hotspot tracks where none existed before. A reasonable inference is that these plateaus are the consequence of the impacts of large meteorites. This is particularly the case with the Deccan Plateau, which is agedated as synchronous with the Cretaceous-Tertiary Boundary event, with its legacy of worldwide iridium deposits and the wholesale extinction of life. The paper concludes with: "It therefore appears that random encounters with vagrant asteroidal objects play an important role in setting the course of plate tectonic events. The earth does not control its own agenda." (Alt, D., et al; "Terrestrial Maria: The Origins of Large Basalt Plateaus, Hotspot Tracks and Spreading Ridges," Journal of Geology, 96:647, 1988.)

... Science Frontiers ONLINE No. 87: May-Jun 1993 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The earth: a doubly charmed planet In SF#85, we learned that the evolution of advanced life forms on earth may have depended upon the protective influences of Jupiter and Saturn. These two giant planets can gravitationally deflect potentially devastating asteroids and comets away from the earth. It seems now that we are doubly lucky! Computer runs demonstrate that the presence of our large moon has stabilized the earth's spin axis down the eons. Presently, the earth's spin axis makes an angle of 23.5 with the plane of the earth's orbit (its "obliquity"). The well-known result is our yearly procession of seasons. Without the steadying effect of the moon, however, the earth's obliquity would probably have swung chaotically over much larger values. Such extreme changes would have been inimical to the development of life, particularly advanced life. As a case in point, the polar axis of Mars, with only two tiny moons to dampen its spin excursions, seems to have gone through many wild swings, as indicated in the figure. What deadly climatic changes must have wracked our sister planet! (Touma, Jihad, and Wisdom, Jack; "The Chaotic Obliquity of Mars," Science, 259: 1294, 1993.

... a decade ago. Its composition and fused crust suggest an extraterrestrial -- origin probably Mars. Space scientists think ALH 84001 was blasted off the Martian surface by an impacting body 14-18 million years ago, based upon its exposure to cosmic rays while circling the sun, edging ever closer to earth. The composition of ALH 84001 tells us curious facts about its place of origin. First, it contains carbonate minerals deposited by water. Second, the carbonate grains are banded, implying the parent rock formation was washed by water more than once. Third, and most interesting, chemists have found traces of molecules called PAHs, based on interconnected benzene rings. Three sources have been proposed for these PAHs: Terrestrial contamination Prebiotic activity on the planet of origin PAH-bearing comets and/or asteroids impacting the parent planet. Terrestrial contamination has always been a problem in analyzing meteorites, but great care has been taken in recent years, especially with the Antarctic lode of meteorites. In view of these precautions, it seems rather likely that somewhere "out there" life is brewing. (Anonymous; "A Chip Off the Old Mars," Sky and Telescope , 90:12, July 1995.)
