We introduce here a remarkable theory of terrestrial catastrophism that seems to be supported by evidence that is equally remarkable. One of the authors of this theory (RBF) is identified as a nuclear scientist at the Lawrence Berkeley Nuclear Laboratory. The second author (WT) is a consultant. The authors' credentials seem so good that we must take a close look at their extraordinary claims concerning a natural phenomeon that they believe reset radiocarbon clocks in north-central North America and -- potentially -- elsewhere on the planet. We will be most interested in the reception accorded these claims by the scientific community. The claims. In the authors' words: Our research indicates that the entire Great Lakes region (and beyond) was subjected to particle bombardment and a catastrophic nuclear irradiation that produced secondary thermal neutrons from cosmic ray interactions. The neutrons produced unusually large quantities of 239Pu and substantially altered the natural uranium abundances (235U/238U) in artifacts and in other exposed materials including cherts, sediments, and the entire landscape. These neutrons necessarily transmuted residual nitrogen (14N) in the dated charcoals to radiocarbon, thus explaining anomalous dates. Some North American dates may in consequence be as much as 10,000 years too young. So, we are not dealing with a trivial phenomenon! Supporting evidence. Four main categories of supporting evidence are claimed and presented in varying degrees of detail ...

... Whitesides, at Harvard, has dumped large quantities of millimeter-size iron balls into a plastic dish and then spun a bar magnet under the ensemble with startling results. The balls swarm around inside the plastic dish as the magnet rotates. At first the swarm is disordered. But after a minute, it breaks up into a set of concentric rotating rings. Within each ring, the balls follow one another along precise tracks, as if hugging the rim of an invisible roulette wheel. Soon the balls in each track are perfectly equidistant. Finally, one ball in each ring comes to a dead stop. The other balls in each track line up behind the leader in a tiny arc, even though the magnet is still whirling away below. Example 2. In water, large, fatty molecules (phospholipids) are observed to self-assemble into double layers with their water-loving bonds pointing outwards. This sort of structure closely resembles that of the biological membranes so vital to terrestrial life. This potentially biologically useful structure self-assembles! It seems that on the mesoscopic scale, under certain conditions, ensembles of particles (e .g ., iron balls and large molecules) may snap into "dominant states" that exhibit unexpected properties. In this context Nobelist R. Laughlin remarks: The discoveries that matter are the grand surprises that occur when matter organizes itself. Of course, the question has always been whether something "special" or "vital" has to be done to an ensemble of molecules to confer life upon it. In his Darwin's Black Box ...

They have to be because life is conferred by the flow of information. We all learn how the nervous system carries a heavy traffic of electrical signals, but we hear less about chemical signals, and they are more important. Chemical signalling molecules help cells learn what is going on around them so that they can make decisions concerning metabolism, division, and even whether to die not not. This is mainstream biochemistry, although there is much here yet to be learned. A signalling medium that still survives well off the mainstream is the old idea that information is carried from cell to cell via electromagnetic radiation. Yes, we mean mitogenetic radiation--the infamous M-rays of the 1920s and 1930s. During this period about a thousand technical papers were published on mitogenetic radiation -- mostly in Russian. The champion of mitogenetic radiation was A.G . Gurwitsch. He claimed that fundamental biological functions, such as cell division, were communicated via ultraviolet light. Although a few other researchers said they detected mitogenetic radiation, most could not replicate Gurwitsch's work. Mitogenetic radiation was thereafter subjected to the "cold-fusion" treatment; it was one of those things that "wasn't so"! In a recent article in the Journal of Scientific Exploration, R. Van Wijk tries to reignite interest in "bio-photons" that carry "bio ...

Life may have originated and prospered on the multitude of sun-less aggregations of matter drifting through the void, some doubtless quite close to us. Myriad nomadic planets may be roaming our Galaxy free from the clutches of parent stars. Two teams of astronomers think they have detected 25 of these free-floating planets, and say there could be hundreds of millions of them wandering the Milky Way. These free-floaters or "drifters" were created when small clouds of gas and dust coalesced under gravity's urging. If such collapsing clouds were less than 80 times Jupiter's mass, they would not be able to sustain nuclear reactions and become long-lived stars. Many would be-come "brown dwarfs." Still smaller aggregations -- less than 14 Jupiters -- would never shine at all. These would remain warm for a while as they dissipated the gravitational energy that created them. Such small objects would be temporarily detectable by infrared telescopes. Hundreds of such infrared "point sources" turn up in sky surveys. These are the only "drifters" we can detect. "Drifters" that have already cooled off are certainly out there by the hundreds of millions. (Muir, Hazel; "The Drifters," New Scientist, p. 14, April 1, 2000.) Comments.

Human beings certainly seem irreducible; and some proteins are so large and complex that one is unsure that physics is up to the task of explaining these tangled structures consisting many hundreds of atoms. Some of these doubts have been relieved by recent advances in protein chemistry. It appears that the different types of protein folds, which number in the thousands, can be classified and sorted into distinct structural families -- just like the much simpler crystals of salt, quartz, galena, etc fall into orderly classes. The clear implication is that protein folds and, by extension via further research, the protein molecules themselves, are also natural and reducible just like the salt crystals. If proteins are natural, perhaps even more complex biological forms are also, and so on up the complexity ladder to viruses (which often look like crystals through the microscope), bacteria, and even (gasp!) mammals. This is, of course, reductionism in the extreme. But the successes with protein folding have led two New Zealand biochemists to speculate as follows: If it does turn out that a substantial amount of higher biological form is natural, then the implications will be radical and far-reaching. It will mean that physical laws must have had a far greater role in the evolution of biological form than is generally assumed. And it will mean a return to the pre-Darwinian conception that ...

In other words, consciousness is something "special" that makes us more than automatons. Other animals may be automatons, but not us! D. Jones speculates in Nature that if consciousness is a definite, inheritable characteristic, it must have had survival value for it to have evolved. It then follows that consciousness must be en-coded somewhere in our genes. Only a single gene may be enough, for consciousness seems to be an uncomplicated phenomenon. Why? Because just a few simple molecules, such as those found in anesthetics, can disable it completely without affecting other bodily functions. Eventually, Jones continues, the gene (or small number of genes) responsible for consciousness will be identified. Then, we can determine for certain if any of the lower animals are also conscious. We think chimps and dolphins might be, but we're not really sure until we see if they have the necessary genes. In fact, the old-time behaviorists could be right, and all the other animals really are merely automatons. That would definitely make us "special"!

There is simply not enough helium escaping from earth's crust to account for the heat flowing outwards from our planet's core. You see, most of the earth's internal fires are fueled by the radioactive decay of uranium and thorium. The heat produced by these disintegrations eventually makes its way to the surface where we can measure it. but the helium (4He) created by the radioactive decay of the uranium and thorium is mostly missing. The discrepancy is large, and scien tists are confronted with the possibility that we are wrong about either the source of the earth's heat or the facts of nuclear physics. You can bet it will not be the latter. We are confident that helium atoms cannot change their type like those solar neutrinos!

"He says his cold-fusion cell produced excess heat at an average rate of 100 watts for months at a time. That's up to 40 times more power than he was putting into the cell, and more power per unit volume (of palladium) than is generated by a fuel rod in a nuclear reactor. " Takahashi has made several modifications in his cold-fusion cell. Rather than palladium rods, he employs small sheets. In addition, surmising that cold-fusion phenomena might prosper better under transient conditions, he varies cell current.

But galaxy NGC4138, 50-million light years away, defies this common-sense expectation. M.

There are even computer models being developed, based on a branch of mathematics called "dynamical systems," that describe how this all happens - spontaneously, of course. (Waldrop, M. Mitchell; "Spontaneous Order, Evolution, and Life," Science, 247:1543, 1990.) Comment. When water molecules spontaneously cluster together to form a snowflake, with all its symmetry and order, science explains the process in terms of the properties of water molecules. The same must be true when molecules merge to form life forms. But ...

Approximately 10-10 seconds after the Big Bang, the force laws changed discontinuously as the universe cooled. Some models of the cosmos predict that another such phase change may occur when photons suddenly acquire mass. Grone and Sher have sketched the effects on terrestrial civilization: "The most dramatic effect would be the elimination of all static electric and magnetic fields over a range greater than 1 cm, and the elimination of all electromagnetic radiation with frequencies smaller than a few hundred gigahertz. We have shown that there would be relatively little impact on atomic structure and on solar radiation. The absence of electrostatic fields would force a redesign of current power plants (to use smaller solenoids); the absence of radio and television waves would force a much greater use of cables. The elimination of solar and geomagnetic fields would have a significant meteorological impact. The potential ly most devastating effect could be on the propagation of neural impulse along motor neurons; it appears that the effects might be small, but they do depend on the precise value of the photon mass."

First, a tad of background: Great meteor impacts and tektite events seem to have occurred nearly simultaneously with deep-cutting biological extinctions and reversals of the earth's magnetic field.

The stimulus in this case is the morethan-a -decade-old inability of astronomers and physicists to explain the missing solar neutrinos.

Such finds have forced hydrologists to question their traditional belief that deep aquifers were devoid of life. But it was not clear whether these bacteria were native residents of the aquifers or just contaminants from the world above, living solely within the wells. Moreover, no one had established how the bacteria were affecting the environment, if at all." Experiments have now shown that these subterranean bacteria are indigenous and are important to groundwater chem istry. The bacteria feed on organic molecules and display a curious propensity for metabolizing the carbon-13 isotope rather than carbon-12.

Science Frontiers ONLINE No. 47: Sep-Oct 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Earth's womb Three recent items indicate that scientists are now recognizing how the earth's crust is tailor-made for biochemical reactions of great variety and complexity. First, E.G . Nisbet explains how subsurface hydrothermal systems are ideal places to make biochemical products, particularly in the light of the discovery that RNA molecules can extrude introns and then behave like enzymes. "The most likely site for the inorgan ic construction or an RNA chain, which would have occurred in the Archaean, is in a hydrothermal system. Only in such a setting would the necessary basic components (CH4 , NH3 , and phosphates) be freely available. Suitable pH (fluctuating around 8) and temperatures around 40 C are characteristic of hydrothermal systems on land. Furthermore, altered lavas in the zeolite metamorphic facies, which are rich in zeolites, clays and heavy metal sulphides, would provide catalytic surfaces, pores and molecular sieves in which RNA molecules could be assembled and contained. If the RNA could then replicate with the aid of ribozymes and without proteins, the chance of creating life becomes not impossible but merely wildly unlikely." The article concludes with a statement that self-replicating molecules synthesized in hydrothermal systems would be pre-adapted to "life" in the open ocean if they "learned" to surround themselves with bags of lipids. (Bag of lipids = a membrane.) (Nisbet, E.G .; " ...

Some very suggestive evidence has turned up that giant nuclei are being formed with atomic weights and numbers approximately double those of the colliding nuclei. The words "giant nuclear molecule" and "giant di-nuclear system" are being bandied about. Two nuclei of uranium-238 might, for example, unite for 10-19 second in a supernucleus. As the author of this article says, "What is going on?" (Silver, Joshua; "Giant Nucleus at Darmstadt?" Nature, 315:276, 1985.) From Science ... #40, JUL-AUG 1985 . 1985-2000 William R. Corliss ...

... Science Frontiers ONLINE No. 39: May-Jun 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Anomalous Anomalons Anomalons are fragments of atomic nuclei that interact with other nuclei more readily than expected. They seem to represent a previously unknown and highly reactive state of nuclear matter. Not all physicists can find them experimentally; and far from all believe they exist. Until now, only large nuclear fragments have been found to be anomalons. But some Indian physicists working in the USSR have bombarded carbon-12 nuclei with carbon-12 nuclei and found anomalously active alpha particles in the debris from the collisions. Not all of the alphas were anomalous, which makes the situation all the more mysterious. Just what makes a law-abiding alpha particle (a combination of two protons and two neutrons) into a highly reactive anomalon? (Anonymous; "More Anomalous Nuclear Fragments," Science News, 127:105, 1985.) Comment. This is the first case of very small anomalons. There does not seem to be much one could do to something as simple as an alpha particle to make it more reactive. From Science Frontiers #39, MAY-JUN 1985 . 1985-2000 William R. Corliss ...

Science Frontiers ONLINE No. 46: Jul-Aug 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Halley's comet infected by bacteria?" Halley's comet is coated with organic molecules. Two astronomers working with the Anglo-Australian Telescope, David Allen and Dayal Wickramasinghe, have found strong evidence in an infrared spectrum of the comet, taken two weeks ago. The spectrum, spanning the wavelengths 2-4 micrometres, shows a prominent feature centred at 3.4 micrometres which the two astronomers attribute to emission by carbon-hydrogen bonds in a solid." Chandra Wickramasinghe (Dayal's brother) states that the emissivity of Halley's comet matches exactly the emissivity of bacteria as observed in the laboratory. This observation supports the Hoyle-Wickramasinghe suggestion that comets transport life forms around the universe. Of course, more conservative scientists contend that rather complex organic molecules can be synthesized in space abiogenically. These molecules might account for the observations. (Chown, Marcus; "Organics or Organisms in Halley's Nucleus," New Scientist, p. 23, April 17, 1986.) Comment. This article seems to be accompanied by a bit of scientific revisionism. In response to this discovery, one English scientist remarked that these results, ". .. only confirm what everyone has always suspected." Now, it is true that comets have long been termed "dirty snowballs" but until very recently no one has maintained that comets are covered with dark, organic sludge. Reference. In category ...

... military sensitivity was, and still remains, a mystery." (McKenna, Daniel L., and Walker, Daniel A.; "Mystery Cloud: Additional Observations," Science, 234:412, 1986.) Evidently the mystery cloud mentioned above is only one in a long series: "Large icy clouds, similar to plumes of gas that rise over volcanoes, have appeared over islands along the coast of the Soviet Union during the past several years, baffling experts, who cannot explain what they are or what causes them. "The clouds dissipate in a few hours vanishing as mysteriously as they appear. "Among the plumes are a series of massive clouds that during the past four years have periodically swelled over Novaya Zemlya, the Arctic island long used by the Soviets for nuclear weapons tests. "However, there appears to be no correlation between the clouds and known Soviet tests, which are usually detected by Western governments. Further, non-governmental scientists said the 200-mile-long plumes appear to be many times larger than the largest conceivable nuclear explosion could produce." A NOAA satellite detected a large plume coming from the Arctic Ocean near Bennett Island, north of the Soviet Union, in 1983. Three distinct sources were found; one on the island and the other two about 9 miles offshore on the ice-covered ocean. This plume was 6 miles wide, 155 miles long, and 23,000 feet high.
