Specifically, galaxies 10 billion light years away differ little spectrally speaking from those only a billion light years away. The point is that the distant galaxies should appear 9 billion years younger because their light took that long getting here. They look the same, and that fact could imply: (1 ) Galaxies mature rapidly and do not change much after a billion years; (2 ) Our cosmic time scale is all wrong; (3 ) There was no Big Bang and galaxies may have widely varying ages; or (4 ) None of the above.

... Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Cosmic Death Waves In the language of science, W.M . Napier and S.V .M Clube provide a scenario of cyclic terrestrial catastrophism. Their thesis is that the solar system periodically passes through the regularly spaced spiral galaxy arms every few 107 years. Planetesimals in these arms cra-ter the solar-system planets at these times and also provide the raw materials for new comets, asteroids, satellites, and even planets. Supporting their theory is the repeating history of geological revolutions with the accompanying extinctions and reflowerings of life. A remarkable feature of this paper is a table of shortlived solar-system phenomena (comets and rapidly evolving staellite-and-ring systems). The tenor is one of episodic catastrophism and a rapidly changing solar system; viz., Saturn's rings evolving in only 104 years.

These experiments are not yet conclusive; and if the neutrino mass is not zero, it hardly weighs more than the grin of a Cheshire cat. But taken together, the laboratory results confirm that neutrinos are perplexing particles. Are they different entities or a single species wearing different costumes? The implications of the recent measurements are far-reaching: Physicists believe that there are a billion neutrinos around for each nucleon (proton, neutron, etc.) so that if neutrinos possess just a hint of mass, they will dominate the mass of the universe; and Measurements of solar neutrinos fall short by a factor of three of what theory says the sun should spew out. This discrepancy could be explained if the solar neutrinos change from electron neutrinos to another form during their flight from the sun to earth, for the terrestrial neutrino detectors measure only electron neutrinos.

Accelerator experiments at Berkeley have again focussed attention on those few fragments from nuclear reactions that have unexpectedly short trajectories. About 6% of these fragments travel only about one tenth as far as prevailing physical laws say they should. These anomalously short mean free paths are not new, having first cropped up in 1954, but they have gone unexplained for 26 years. Current speculation is that the anomalous fragments somehow change their identities, making them more susceptible to collision (i .e ., their collision cross sections spontaneously increase by ten times). But no known transformations of matter can do this! Consequently, we are left with the possiblity that some entirely new form of matter exists.

This long, highly technical article is replete with circuit diagrams, photos of shiny equipment, charts, and the complete panoply of modern scientific research. In the section on psychokinesis, we read about Fabry-Perot interferometers, dual thermistors, glow-discharge experiments, Gaussian analog devices, etc. (There is a companion section on remote viewing experimentation!) To round out this overview, the section on historical/philosophical background and the superb bibliography must be mentioned. Although Jahn regards his work as only beginning, he does feel that the early results clearly show the existence of non-chance factors in psychokinesis and remote-viewing experiments.

Williamson has scrutinized the distribution of some 190 faunas with high stratigraphic resolution; that is, he believes he has been able to sketch for the first evolutionary events on a fine time scale. Williamson underlines three important observations: (1 ) Species seemed to arise suddenly, as predicted by the "punctuated evolution" model; (2 ) The formation of new species was accompanied by marked developmental instability in the transitional forms; and (3 ) All lineages were morphologically stable for long periods -- they did not change form! The biological implications of this important study are summarized in the preceding item. (Williamson, P.G .; "Palaeontological Documentation in Cenozoic Molluscs from Turkana Basin," Nature, 293:437, 1981.) Comment. Evolutionists have often bewailed the obvious lack of transitional forms (missing links) in the stratigraphic record. According to Williamson's results, transitional forms would be few in number and display considerable morphological instability.

Evolution thus occurs at DNA and gene (genome) levels, despite what transpires at the organism (phenotype) level. (Doolittle, W.

Specifically, individuals can be commanded to appear and the action controlled to please the dreamer. As Keith Hearne, a dream researcher, remarks with tongue-in-cheek, the entertainment possibilities are endless if lucid dreaming could be induced in everyone! Lucid dreams are so real that the dreamer will sometimes believe that he has awakened and answered questions from the researcher, when nothing like that has happened. Lucid dreaming occurs only during periods of REM (Rapid Eye Movements) sleep. The lucid dream-er, however, can signal the dream researcher that lucid dreaming has begun with agreed-upon eye movements and changes in the rate of breathing. (Hearne, Keith; "Control Your Own Dreams," New Scientist, 91:783, 1981.) Comment. The fact of lucid dreaming encourages many questions. How is it related to out-of-the-body experiences and hallucinations? Pertinent once more is that old philosophical teaser: How do we know that reality is not a dream from which we shall soon awaken?

One type of nomad is a simple ring of DNA called a plasmid.

Plasmids have been discovered in maize, fruit flies, bacteria, and, now, humans -- and healthy people at that. No one is quite sure what these plasmids do.

The subject of this book is "gene-culture coevolution," which infers that human culture is controlled not so much by "free will" as by rapidly changing human genes. The authors propose that as few as 1000 years are sufficient for important genetic shifts. Such shifts might, for example, impel humans to break out of the Middle Ages and bring on the Industrial Revolution. The most controversial facets of the theory are: (1 ) The tight genetic control over human culture with little room for free will; and (2 ) The rapid blossoming of many cultures as genes shift about.

At the time, such results were not so shocking. Indeed, some philosophers had shown that Special Relativity led to undesirable paradoxes, and experiments by Sagnac and Michelson/Gale had cast additional doubt on this aspect of Relativity. Such experiments by Ives and other key scientists suggested that an ether actually did exist and that it could serve as an absolute reference frame. Another implication was that time was an independent entity unaffected by motion and that the infamous Twin Paradox was a fiction. Ives himself believed his work proved that so-called relativistic effects could be easily explained by phenomena appealing more to the common sense, such as the change of a light source's frequency with motion (over and above the Doppler Effect), rather than revamping space-time concepts. In short, Ives thought he had proved Special Relativity untenable experimentally and an un-necessary distortion of science's worldview.

Pollen studies of the core indicate a brief decline of forest pollen about 17,800 BP along with increased sedimentation characteristic of cleared land.

Gould, who conducts a monthly column in Natural History reviews the sad history of Goldschmidt and his villification by the scientific establishment. Goldschmidt saw the fossil record as woefully inadequate to justify the assumption of gradual evolution of one form into another. Intermediate forms between separate species do not seem to exist in the fossil record and, if they did, they would probably not have been viable creatures. What good is half a wing? Gould believes that Goldschmidt's "hopeful monster" concept will ultimately be dusted off. The key to "macromutation," Gould feels, is not to be found in major gene reorganizations that might produce a whole wing, feathers included, all at once, but rather in changes in the genes that control the development of embryos. Embryos in their early stages are pretty much alike regardless of species. Gould hopes further that the ruling neo-Darwinians will not be so hostile to new ideas and eventually acknowledge Goldschmidt's important work.

The first group lasted 10 seconds, with a 15-second quiescent period before the second group. The second group lasted about 5 seconds. About 30 straight parallel, regularly spaced bands appeared during the first observation. Moving steadily, they took 2 seconds each to cross the arc of contact.

Two questions must be answered: (1 ) Why is the incidence of diabetes mellitus only 8% among American junkfood-eating couch potatoes? Probable answer: natural selection has already modified the American genotype by eliminating those who are supersensitive to diabetes mellitus under conditions of rich diets and sedentary lives.

In fact, "time" then might have been different from "time" now. This sounds like so much physics-speak; but, seriously, during the birth pangs of the universe, there seems to have been what cosmologists call a "phase change," a mysterious moment when the laws of physics suddenly became more complex. You can reasonably ask: "How can supposedly immutable physical laws change?" The answer seems to be that anything can happen when something is being made from nothing! This apparent plasticity in the laws governing the cosmos is suggested by observations of how galaxies in the early universe were distributed. The standard theory for the origin of the universe predicts that clumps of galaxies of all sizes were created early on. This is not what a survey by S. Sarkar et al, at the University of Oxford, found. A split second after the Big Bang, galaxies were organized in structures about 300-million light years across. The standard model of particle physics cannot account for this preferred size. The theorists' recourse is a phase change, a point in time when the warp and woof of the universe changed; that is, change the rules until they fit. (Chown, Marcus; "In the ...

(SF#110) The media have said little about the staggering quantities of methane and higher hydrocarbons locked up in frozen hydrates around the edges of the continents. Actually, the small methane burps are minor problems compared to the catastrophic climate changes that could be forced if just a small portion of the gases frozen under the sea floor were released into the atmosphere. Gas-hydrates are unimpressive when brought to the surface -- just dirty, fizzy ice. However, taken together, they contain more carbon than all the world's oil fields, perhaps much more. Most estimates fall between 1,700 and 11,000 billion tons, but there is one scientist who pegs these cold-storage carbon deposits at 4,100,000 billion tons. In comparison, human releases of carbon to the atmosphere via the burning of wood, gas, coal, and even the collective flatulence of all the planet's animals are trivial. Geological evidence confirms that past climate swings were associated with large injections of carbon into the atmosphere and oceans. A major contributor to these "carbon burps" may be decomposing methane hydrate. Until recently, climatologists have questioned the sizes of gas-hydrate deposits, but cores extracted from the Blake Ridge off the Carolina coast confirm ...

Mainstream scientists always explain NDEs in reductionist terms: they are merely the consequence of physiological changes taking place in the dying person's brain. Parapsychologists are more open-minded. They wonder if being near death breaks down a barrier separating the everyday, objective world from a spiritual one.

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.

A team of Australian astronomers, led by J.K . Webb, has been trying to determine if the famous fine-structure constant of physics has really remained constant throughout the 12-billion years or so of the universe's history. The fine-structure constant is dimensionless and almost exactly equal to 1/137. (Why 137? That's another question!) Anyway, the Australians got a good fix on the constant's value 2 billion years ago by measuring the composition of the nuclear waste produced by the Olko natural nuclear reactors in Gabon, Africa. It hasn't changed since then. The spectra of distant quasars 7 billion years old also signaled no change. But more-distant and, therefore, supposedly older, gas clouds have suggested that a slightly smaller fine-structure constant held sway then. No known experimental error can account for this difference. "If confirmed, would Webb's findings eventually be explained by a deeper theory, vindicating physicists' faith in a uniform nature?

Usually, quakes are confined to the edges of plates where they crunch against neighboring plates. Second, a line of folds 3,000 feet high runs down the center of the plate, as if is being squeezed like an accordion. But they could not identify any geological accordionist. Finally, working backwards in time using paleomagnetic data, they reconstructed plate configurations 11 million years ago. The Indo-Australian plate did not match up with its neighbors of that time period. Royer and Gordon concluded that the Indo-Australian plate really consists of three smaller plates.

Although its shoreline in complex, there is a deep channel about 2 kilometers wide with steep sides running lengthwise along the lake floor. When wind blows across the lake's surface, wind-drag pushes surface water downwind. When the wind stops or changes direction, the piled-up water is freed, and standing waves are set up as the water sloshes back and forth in the lake basin. These waves are called "seiches." Lakes usually have characteristic periods of oscillation. For Lake Champlain, it is 4 hours, with amplitudes measured only in centimeters on the surface of the water. What makes Lake Champlain of more than usual interest is the presence of a second seiche, an internal phenomenon not visible on the surface. In the summer, Lake Champlain is stratified with a thermocline separating a layer of warm surface water from much colder deep water. You can only "see" the thermocline if you lower a thermometer into the water. This thermocline also exhibits seiches, but they are startlingly different from those on the surface.

... Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Gaia as a super-superorganism The Gaia hypothesis states that the earth's environment is maintained suitable for life by life itself. Our climate, atmospheric oxygen level, ocean composition, and similar vital conditions are kept livable by life's waste products, such as the oxygen emissions of plants. That something like Gaia is required is seen in the extreme disequilibrium of the earth's atmosphere compared to the near-equilibrium of the atmospheres of apparently lifeless Venus and Mars. For example, our atmosphere's 21% oxygen, a highly reactive gas, is many orders of magnitude higher than one would expect on a lifeless planet. Furthermore, life-friendly conditions have been maintained for billions of years despite large changes in the sun's output and the traumas of asteroid impacts. T.M . Lenton, writing in Nature, asks a salient question: How has planetary self-regulation (Gaia) been established and maintained by evolution and natural selection which operate on the level of individuals? In other words, evolution tells us that organisms should evolve so as to leave the most progeny not so as to regulate the atmosphere. Lenton answers that there must be feedback loops from the planetary environment that steer the evolution of individuals in the "proper" direction. Lenton goes on to explore some of these many feedback mechanisms; one obscure loop involves the production of dimethyl sulfide by marine phytoplankton. Truly, it is a tangled bank! All of the feedback loops imply that the evolution of life ...

... Sourcebook Subjects Why Are Dreams Always Retrospective?This question and others regarding dreams have been posed by two French researchers in a new book. One of our French readers has summarized some points made in this new book. "Michel Jouvet, a French specialist of dreams, asks the question: Why do cosmonauts never dream about space? Why do they dream only about the Earth? "According to psychologists, the 'day residue' in dreams is rather important. Half of all dreams allude to events of the preceding day; 89% allude to events of the last 120 days. The older the event, the lower the odds that it will reappear during the night. When people wear colored glasses, they begin very quickly to dream in the same color. People who make a complete change of life; for example, by travelling to a faraway place; do not begin to dream about this new place for weeks or months. A Bassari from Senegal, who was resident in Paris for two extended stays, was asked to write down his dreams. Surprisingly, 88% of his dreams occurred in Africa and only 6% in France. This experiment and others like it are discussed at length in the book, but explanations are lacking. Do we really understand anything about dreams?
