"I regard the failure to find a clear 'vector of progress' in life's history as the most puzzling fact of the fossil record. But I also believe that we are now on the verge of a solution, thanks to a better understanding of evolution in both normal and catastrophic times. We need a twotiered explanation for patterns (or non-patterns) in the history of life." The first tier of explanation involves the theory of punctuated equilibrium, as championed by Gould and Eldredge. Gould says he once thought that punctuated evolution would be sufficient to explain all of life's development, but that now a second tier seemed required; namely, a general theory of mass extinction or what catastrophism does to life and its development.

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?" Sky and Telescope, 68:389, 1984.) An article in Science also discusses the classical theories of lunar origin and quickly disposes of them for the above reasons. However, a fourth theory makes an appearance, which we might call the Big Splash Theory. The idea is that a Mars-sized object (1 /10 the earth's mass) made a grazing collision with the earth when the solar system was more heavily populated with debris. This collision vaporized the projectile's rocky mantle as well as a similar quantity from the earth. This material was flung into orbit by the force of the impact and the expanding hot gases. Beyond the Roche Limit, the expelled debris coalesced into the moon. This fourth theory is now seriously considered by planetary scientists who -- so far -- have found no serious defects.

New cosmic X-ray data from the satellite Ariel 5 suggests that a large, hitherto unsuspected mass is located in the same direction that the earth is moving. Thus, both X-ray and microwave data could be explained by supposing this mass to be large enough to pull the earth (and our Galaxy) toward it. This mass would have to be about 10 billion light years away and weigh as much as 100 million Galaxies. Such a gigantic blob or inhomogeneity in the universe would be very difficult to explain. As it is, the aggregation of stars into galaxies after the Big Bang remains poorly understood. The bigger the inhomogeneity, the harder it is to account for.

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 ...

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.

... Project Sourcebook Subjects Problems At The Rim Of The Solar System Neptune is an undisciplined member of the solar system. No one has been able to predict its future course accurately. 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.

Soft, exposed parts, such as the ears and genitals, were apparently removed with surgical precision. Some corpses seemed bloodless. Local papers blamed satan worshippers and UFO occupants. This paper analyzes the 1974 mutilation "flaps" in South Dakota and Nebraska, with special attention to the rapid rise and equally rapid decline of public interest as measured by newspaper coverage. In the opinion of the author, these two episodes are classic cases of mild mass hysteria, similar to the occasional crazes of automobile window-pitting. In all cases where university veterinarians examined the corpses, the mutilations were ascribed to small predatory animals. The veterinarians also pointed out that blood coagulates in a couple days after death, accounting for the frequent "bloodless" condition. With such expert reassurances, the "mass delusions" subsided quickly. Cattle mutilation flaps are thus seen by the author as episodes when people interpret the mundane in bizarre new ways, due perhaps to cultural tensions. It is noted, however, that expert veterinarians examined only a few of the dozens of mutilations, and that some people rejected the above commonplace explanations.

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.

... to an old (534-millionyears-ago) crustal slippage, whereas Hapgood was talking about a cataclysm within the last 10,000 years or so. Nevertheless, it would have been nice to see Hapgood's earlier work acknowledged. Four features of this "new" proposal make it more palatable than Hapgood's to today's geologists and geophysicists: Two of the "new" authors, J. Kirschvink and D.A . Evans, are at the prestigious California Institute of Technology, while Hapgood was a PhD-less history professor at Keene State College. Status is important when theorizing. Kirschvink et al propose a scientifically acceptable mechanism for the onset of rapid crustal slippage. They visualize a huge chunk of the seafloor suddenly foundering and thereby changing the planet's mass distribution. This imbalance caused the continents to shift rapidly in order to restore the smooth rotation of the earth around its spin axis. Within a period of 15 million years, they envisage, the continents had slipped about 90 . Part of what is now North America moved from the South Pole to near the Equator. Evidence for this huge shift is seen in measurements of the earth's magnetic field frozen in the rocks. In other words, Kirschvink et al used the methods of paleomagnetism. The "new" crustal slippage is really only accelerated continental drift (a dominant and well-established paradigm) and not the more radical notion of the entire outer layer of crust slipping over the earth's mantle like a greased onion skin. Nor is the proposed process anything like poleflipping ...

Dilatons might also explain the formation of the aforesaid galactic shells. "The Mexican researchers have explored a situation in which G [the gravitational constant], instead of becoming fixed after gravity separated from the other forces [after the Big Bang], has continued to oscillate by a few per cent. They have found that the mass of dilatons required to allow G to vary in this way could account for all the Universe's dark matter." A consequence of an oscillating G would be a varying rate of expansion for the universe -- a sort of ebb and flow of the whole cosmos.

Ahluwalia, ventures that an analogous situation prevails with gravity. He notes that General Relativity predicts that a particle (or person) in free fall cannot distinguish this condition (weightlessness) from the situation in a hollow shell of matter, where the gravitational field is cancelled out. A person would feel weightless in both situations. But the strange part arises when one looks at the two situations from the perspective of quantum mechanics; that is, one puts gravity into Shroedinger's equation. Ahluwalia asserts that the particle's (or person's ) gravitational presence is smeared out, just like that of the electron outside the solenoid. In consequence, masses can "feel" their gravitational potential and will behave differently in free fall than when inside a hollow sphere, contrary to what Einstein maintained in his General Relativity.

Similar tests on the media-hyped Martian meteorite ALH 84001 yielded the same carbon ratios. Pillinger remarked: "These results offer the strongest support yet for the hypothesis that life once existed on the planet." So far so good, but EETA 79001 conveys two additional facts -- both very tantalizing: (1 ) This meteorite was blasted off the Martian surface only about 500,000 years ago; and (2 ) It probably came from a different hemisphere than ALH 84001.

... The Terrestrial Conveyor Belt According to plate tectonics, the earth's continents are being transported -- very slowly -- on a subterranean conveyor belt of sorts. Although plate tectonics, nee continental drift, was ridiculed 50 years ago, it has been very successful in accounting for many geological phenomena. The theory is rarely challenged these days, but there are anomalies out there. "According to the simple plate-tectonic theory, the age of oceanic lithosphere is zero at a spreading oceanic ridge and increases with distance from the ridge. Thus the lithosphere of the central Atlantic, which current palaeogeographical reconstructions assure us began to open no earlier than 120 million years ago, has zero age at the Mid-Atlantic Ridge and, supposedly an age of about 120 million years close to the land masses of Africa and South America at the appropriate latitude. Yet, Bonatti and others (Nature, v. 380, p. 518, 1996) have now recovered samples of 140-million-year-old pelagic limestones not even from the edges of the Atlantic but right in the middle of the ocean, close to the ridge.

(Ref. 2) Adding to these problems are nagging doubts about General Relativity, which underpins black-hole theory. Recently, some theorists have shown that General Relativity requires that two bodies of approximately equal size not attract one another! (Ref. 2) Despite all these qualms, black holes have become a fixture of astronomy because they promise to explain the incredibly powerful energy sources seen in the cores of galaxies. Do astronomers really observe black holes? The answer is: MAYBE. And even if YES, there are not nearly enough of them to satisfy theory. To illustrate, according to present theory, when stars weighing in at less than three solar masses collapse, they become neutron stars; if larger, the stars turn into small black holes. Theoretically, there should be one small black hole for every three neutron stars. But with some 500 neutron stars already pin-pointed, only 3 "possible" small black holes have been given votes of confidence; namely, Cyg X-1 , LMC X-3 , and AD 620-00. All objects previously proclaimed to be small black holes have instead turned out to be neutron stars.

Did earth and moon "coaccrete" at the same time? 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.
