Physicists have maintained for over a century that the Second Law of Thermodynamics guarantees that our universe with run down one day and that life must cease. This cold reductionist view is seconded by recent evidence that protons, long con sidered immortal, may after all decay. The consequences of proton decay are even more dismal than the dire predictions of thermodynamics: "Perhaps the most disturbing piece of speculation to come out of theoretical physics recently is the prediction that the whole universe is in decay. Not only do living things die, species go extinct, and stars burn out, but the apparently immutable protons in the nucleus of every atom are slowly dissolving. Eventually -- in more than a quadrillion years -- nothing will be left of the universe but a dead mist of electrons, photons, and neutrinos." (Flam, Faye; "Could Protons Be Mortal after All?" Science, 257:1862, 1992.) The death of memory. With increasing entropy and decaying protons on their minds, it comes as no surprise that physicists likewise believe that when one dies, that's it . An afterlife is impossible. How do physicists conclude this? In a letter to the American Journal of Physics, J. Orear proffered an interesting sort of "proof": "One such proof: human memory is stored in the circuitry of the brain and after death ...

Heckman, of the University of Maryland, has ordained that the apostles of noncosmological redshifts must now recant. He and his colleagues believe that they now have the most convincing demonstration to date that quasar redshifts are of cosmological origin; that is, the larger the redshift, the faster the quasar is receding and the farther away it is. "Availing themselves of the extraordinary new imaging and spectroscopic capabilities of charge-coupled-device (CCD) detectors, they have measured the redshifts of 19 nebulous objects that appear to be companion galaxies of 15 relatively low-redshift quasars. Observing at the Kitt Peak 4-meter telescope, they have determined that, in 18 of these 19 cases, the apparent companion has a redshift very close to that of the quasar. While Burbidge, Arp and their partisans may argue that quasars are so peculiar that they can generate redshifts of unknown origin, this position becomes difficult to maintain for companion galaxies that otherwise look perfectly ordinary." H. Arp and G. Burbidge, chief among those ordered to recant, are not convinced. Arp points to many cases where bridges of luminous material connect high-redshift quasars with low redshift galaxies. Also, the clustering of quasars around nearby galaxies supports the nearness of quasars. As Burbidge has observed, if: ". .. just one large redshift is not due ...

Moliner, a neurologist, has written a curious yet provocative article for New Scientist. It is really a not-too-subtle attack on the Anthropic Principle, Darwinism, and science's insistence that the universe must be purposeless. He notes first that most proponents of the Anthropic Principle postulate that, in the beginning (whatever that was!), many different universes may have been created. The only one we observe is the one offering just the right combination of properties for evolving life and, especially, humankind. If this or that physical constant had been a tad different, humans would not have evolved. Even though humans obviously did evolve, it was all purposeless -- just the way atoms and molecules happened to combine. This outlook fits right in with Darwinism, for almost all Darwinists also see evolution as purposeless. It was blind chance that gave us the capabilities to build aircraft and tunnel into opposite sides of a mountain and meet in the middle. Moliner is highly skeptical that such amazing, "cooperative, adaptive" talents could have come about in an unbiased, purposeless universe. Suppose, he asks, vipers were philosophically minded. They might look at their marvelously complex fangs with the canals inside, a nearby poison gland, a poison storage reservoir with special ducts leading to the fangs, a fang-erection mechanism, a set of muscles to squeeze ...

Getting external funds is impossible unless one can show that your university has enough confidence in the idea to support it financially.

"Suddenly you realize that there is a far more serious problem. The current scientific system is based on the assumption that there is no such thing as a radically new idea.

Because humans "expect" symmetry in nature, it is taken for granted that everything else in the universe is split equally between leftand right-handed molecules. Earth life is just a fluke -- or is it? On September 28, 1969, organic-rich stones fell in Victoria, Australia. This was the Murchison meteorite, and it may carry a message. Over a decade ago, M.H . Engel and B. Nagy reported that the organic molecules in the Murchison meteorite were not split 50:50 between left- and right-handed versions. So contrary to expectations was this finding that most scientists assumed that the analysis was contaminated by terrestrial organic molecules. Now, M.H . Engel and S.A . Macko have refined the analytical techniques and apparently avoided any taint of contamination. Their conclusion: the Murchison amino acids still lean to the left. From all this arise several intriguing possibilities: Life on earth started split evenly between left- and right-handed amino acids, but was nudged to the left by the influx of organic-laden meteorites like the Murchison. Terrestrial life actually originated elsewhere in the universe where much matter is left-handed, including life, if ...

The American archeological establishment has been very skeptical about such claims, but now the 12,000BP barrier seems to be collapsing. The turning point may have occurred at a recent meeting at the University of Maine's Center for the Study of the First Americans. The skeptics were bombarded by radiocarbon dates, tools, hearths, and bones from the Monte Verde site in Chile. Some previouslyunbelieving archeologists are now ready to admit dates around 13,000 BP for Monte Verde. (Lewin, Roger; "Skepticism Fades over Pre-Clovis Man," Science, 244:1140, 1989.) Comment.

(Anonymous; "Massive, Dark Galaxy Found in Void," Astronomy, 15:75, September 1987.) The same discovery is dealt with, in a more technical way, in Nature. A revealing paragraph from the Nature article follows: "Although Malin 1 could be a unique case there is in fact a significant body of circumstantial evidence to suggest otherwise. Our present knowledge of the galaxy population is so biased by a single insidious selection effect that it is entirely possible that Malin 1 is just the first example of a class of such low-surface-brightness giant galaxies that forms a significant constituent of the universe." The "selection effect" mentioned is a consequence of the very bright sky that confronts astronomers. Astronomical interest and instrumentation have focussed on those astronomical objects that are bright. In truth, the universe may be full of "icebergs and crouching giants." (Disney, Michael, and Phillipps, Steven; "Icebergs and Crouching Giants," Nature, 329:203, 1987.) Comment.

This fact does not mean that it is easy to understand. In fact, there are eight competing "interpretations" of quantum mechanics, none of which is completely convincing. No wonder, because quantum mechanics implies four characteristics of the universe that are seriously at odds with our everyday experience: The quantization of the properties of matter; The probabilistic nature of physical measurements; Entanglement; that is, the mysterious instantaneous connection of objects and processes across immense distances; and Superposition; for example, an electron is both here and there until we look at it! A. Zeilinger, University of Vienna, advances the idea that we can truly understand quantum mechanics only when we discover an underlying principle -- something akin to the concept of energy which led to the quantification of the laws of thermodynamics. (Incidentally. we only think we know what energy is, but it is a human construct and is not a physical dimension like mass or distance.) Zeilinger asserts that the underlying principle of quantum mechanics is the quantization of information. Every inquiry science makes into the nature of the universe, says Zeilinger, can be reduced to a yes-or-no question; i.e ., a 1 or 0. To a scientist, nature is really like a person on a ...

It interacts with Normal Matter (us and our instruments) only through its gravitational pull. The Mirror-Matter concept has been around since the 1950s because physicists needed (and still need) "something" that balances the universe -- which if you haven't noticed is asymmetrical. To illustrate this cosmic "deformity," note that Normal-Matter neutrinos always spin in the same direction, when half should spin one way and half the other way if the universe is symmetrical. However, the existence of Mirror-Matter neutrinos spinning the other way would redress things, making the universe "perfect" -- at least as far as human aesthetics are concerned. (Other entities might yearn for asymmetry, who knows?) Anyway, Mirror Matter is defined as being palpable and could also be that "missing mass" or "dark matter" that astronomers need to explain why spinning galaxies do not fly apart. Mirror Matter could also account for some mysterious terrestrial phenomena such as that unaccountable lack of a significant crater in Siberia, where the 1908 Tunguska blast leveled a huge forest but hardly disturbed the ground. Recently, Mirror Matter has been invoked to explain the ups and downs of terrestrial biodiversity. R. Foot and Z. Silagadze propose that the 26-millionyear periodicity ...

In some situations, though, the increase in disorder (entropy) in one part of the universe can create order elsewhere. For example, if you add tiny plastic spheres of two sizes to salty water, you will not get a uniform mixture. Instead the larger spheres will pack together into tightly ordered crystaline shapes (representing more order) while the smaller spheres become more disordered. It is like watching cream unstir itself from coffee. It smacks of magic, but it is all within the laws of thermodynamics. This strange "force" exerted by entropy may explain some puzzling biological phenomena, such as the expulsion of nuclei from mammalian red blood cells before they enter the bloodstream as sacks of hemoglobin. The idea being that the increasing entropy of the proliferating hemoglobin molecules (analogous to the smaller spheres) is maximized when the nuclei (large spheres) are squeezed out of the cells altogether. (Kestenbaum, David; "Gentle Force of Entropy Bridges Disciplines," Science, 279:1849, 1998.) Comments.

A team of seven astronomers first measured the velocities of the elliptical galaxies relative to the earth. Next they subtracted out the velocities of universal expansion and, lastly, the velocity of the earth relative to the 3 K cosmic background radiation. These subtractions enable us to determine how the 390 elliptical galaxies move relative to the cosmic background radiation -- which is about the best fixed reference frame we can come up with. For roughly 50 million parsecs in all directions from earth, the clusters and superclusters of galaxies are streaming through the cosmos in a group. What's more, they lie in and move parallel to a fairly well-defined plane. Just what this coordinated motion means in terms of the origin and evolution of the universe is anyone's guess.

His philosophical objcections to the Big Bang are powerful: "For one thing, the implication is that there was an instant at which time literally began and, so, by extension, an instant before which there was no time. That in turn implies that even if the origin of the Universe may be successfully supposed to lie in the Big Bang, the origin of the Big Bang itself is not susceptible to discussion." The Big Bang, Maddox says, is no more scientific than Biblical creation! The scientific objections involve space, time, the curvature of space.

A wider search undoubtedly would have netted many more, because dark matter is worrying a lot of astronomers. Observations of visible matter, the only kind we can see directly, suggest that most of the universe is, in fact, composed of dark matter. This conclusion comes mainly from the belief that something unseen (dark matter) is tugging on visible matter, making it do things the laws of motion say it should not do. All visible bodies, therefore, seem to be careening about in a dense cloud of unseen, unknown masses. These might be dark, Jupiter-sized objects, black holes, and/or some exotic forms of matter. We must choose between the reality of dark matter or admit that something is awry with our laws of gravitation and motion when they are applied on a cosmological scale Now, let us examine those four darkmatter items from the recent literature: D. Lin, a University of California astronomer, has shown that the Large Magellanic Cloud that orbits around our own galaxy (the Milky Way) is being torn apart (" cannibalized") by the powerful gravitational pull of a dense cloud of dark matter surrounding the Milky Way.

She says, "The stakes in this dispute are high, indeed. If directed mutations are real, the explanations of evolutionary biology that depend on random events must be thrown out.

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.

Gompertz, an actuary, crafted an empirical law stating that mortality rates increase exponentially with age. Later analyses of census records indicated that the situation was not quite as bad as Gompertz had supposed. Nevertheless, the death rate does increase with age; but we might be able to do something about it. Immortality might be achievable -- if we take recent medfly studies seriously. "Growing old does not increase your immediate risk of dying -- at least, if you are a fruit fly. The chances of a Mediterranean fruit fly ( Ceratitis capitata ) dying on a particular day reaches a peak and then declines, according to James Carey of the University of California at Davis and James Vaupel of Duke University, North Carolina, and Odense University in Denmark. Their results contradict the notion that the death rate rises with age in all species." The upshot is that there may be no genetic limit to an individual medfly's lifetime.

But, as just reported by Koo and Krone, the phenomenon is also seen with optical instruments. The red shifts are not entirely due to the Doppler Effect and the recessional velocities of galaxies.

He adds: "There are a lot of fundamental assumptions we base our model on that may be wrong." A leading Big-Bang basher in H. Arp, of whom we have written frequently in SF. We will therefore not pursue his sort of bashing any further here. It is sufficient to say that Arp's doubts about the red-shift/distance relationship continue to receive support through observations of the heavens and in the lab. The other Big-Bang basher featured in Scientific American is H. Alfven, a Nobel-Prize winner in physics. Alfven postulates a universe dominated by electromagnetic forces, which he believes to be more important in shaping the cosmos than gravitation. His electromagnetic theory disallows any universe smaller than 1/10 the diameter of our present universe, thus excluding the Big Bang's point origin. Electromagnetic forces can account for all types of galaxies without resorting to the infamous "missing mass." Alfven can even account for the cosmic microwave background. Furthermore, Alfven's theories are supported by observations of solar-system plasma and magnetic fields. NASA's T.E .

Many cosmologists advance the socalled Anthropic Principle, which states that the physical constants of nature are honed to just the right values to make life possible. If the charge on the electron were a little less or the properties of carbon a bit different, life could not exist. The Anthropic Principle seems to imply that the universe was designed for earth life. But "design" is a bad word these days. It is redolent of purpose and a supernatural being. Suppose, though, that the Anthropic Principle is correct but only in our part of the cosmos and only for a little while. If the constants of nature are not really constant, life could be just a transitory phenomenon, flaring up here and there wherever conditions are ripe and the Anthropic Principle reigns. The cosmos as-a -whole might be lurching toward other goals or, perhaps, toward nowhere in particular. Enough philosophy! 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.

Bahcall said of the discovery that the very early universe was already partitioned by colossal walls of galaxies hundreds of millions of light years long. That walls of galaxies exist is not a new idea, but finding that they existed shortly after the Big Bang is highly disconcerting to most astronomers. How did these walls form so early? Why hasn't the force of gravity modified the basic structure of the cosmos over the billions of years that followed the Big Bang? The astronomical quandry is this: If the very early universe looks pretty much the same as today's universe, the implication is that mass, the source of gravitational sculpting, is scarce. But this is at odds with the cosmic expansion rate which implies a much higher density of matter. (Appenzeller, Tim; "Ancient Galaxy Walls Go up; Will Theories Tumble Down?" Science, 276:36, 1997.) Comment. The existence of galaxy walls, like so many astronomical constructs, depends upon the assumption that the red shifts of galaxies are proportional to their recessional velocities and, additionally, their distances and ages. So much rides on this one assumption. The same situation prevails in biology, where everything is founded on the assumption that random mutations and natural selection can together generate any degree of complexity, sophistication, and innovation seen in nature.

Burbidge, an astronomer at the University of California at San Diego. Her assertion echoes what Arp has been proclaiming for years. (AR#3 ); namely that some redshifts are not due to the Doppler effect and an expanding universe. Since redshift is the major cosmological yardstick, the whole fabric of modern cosmology would become unwoven if redshifts cannot be used to measure distances reliably. We bring this subject up once more because Burbidge claims that some newly discovered quasar pairs cast additional doubt on redshift distance measurements. For example, she, along with Arp and Y. Chu, point to the quasar pair flanking the galaxy named Arp 220 (one of Arp's earlier discoveries). Quasars are very energetic sources of visible light, radio waves, and X-rays. The problem with Arp-220's flanking quasars is that they have much greater redshifts than the galaxy that seems to be situated in between them and likely at the same distance. Is this just a chance association, and the quasars are really much farther away than the galaxy -- as suggested by their high redshifts? Most astronomers believe this must be the case, but Burbidge and, of course, Arp, doubt it. They point to 10 other galaxies nearby that are also straddled by quasar pairs with higher redshifts.

Unless you have been comatose the past several years, you must know that the entire outlook of science is in flux. The words "chaos" and "complexity" are the current buzz words. They betoken, finally, the formal recognition by science that nature is frequently: Unpredictable (as in weather forecasting beyond a few days) Complex (as in any life form) Nonlinear (as in just about all real natural phenomena) Discontinuous (as in saltations in the fossil record) Out-of-equilibrium (as in real economics) Eroding fast are the philosophical foundation stones of the clockwork universe: the idea that nature is in balance, that geological processes are uniformitarian, that life evolved in small, random steps, and that the cosmos is deterministic.

Spaceships are always whisking off into hyperspace. But can we prove that more than three spatial dimensions exist? Shu-Yuan Chu, University of California at Riverside, has shown theoretically that in a five-dimensional world (4 of space, 1 of time) electric charge need not be conserved. This opens up an experimental avenue to test for an extra spatial dimension. For background, recall that physicists originally maintained that mass and energy had to be conserved separately. Then, Einstein came along to show that mass and energy could be interchanged, via E = mc2 , but that they had to be conserved together. In Shu-Yuan Chu's five-dimensional universe mass and charge can be interchanged, but their sum must be conserved. In other words, there exists an E = mc2 equivalent for mass and charge in five dimensions. We could look for this extra spatial dimension by looking for a particle that can be converted into another particle with the same mass+ charge, but made up of a different combination of mass and charge. If such reactions exist, we may be able to explore hyperspace in fact rather than in science fiction. (Gribbin, John; "Can Electric Charge Be Destroyed?" New Scientist, p. 16, October ...

Of course, we cannot really tell for certain because an antimatter galaxy would appear to us just like a galaxy composed of ordinary matter.

It has long been a cornerstone of modern science, to say nothing of man's cosmic outlook, that the earth attends a modest star that shines in an undistinguished part of a run-of-the-mill galaxy. Life arose spontaneously and man evolved on this miscellaneous clump of matter and now directs his own destiny without outside help. This cosmic model is supported by the Big-Bang and Expanding Universe concepts, which in turn are buttressed by the simple observation that astronomers see redshifts wherever they look. These redshifts are due, of course, to matter flying away from us under the impetus of the Big Bang. But redshifts can also arise from the gravitational attraction of mass. If the earth were at the center of the universe, the attraction of the surrounding mass of stars would also produce redshifts wherever we looked! The argument advanced by George Ellis in this article is more complex than this, but his basic thrust is to put man back into a favored position in the cosmos. His new theory seems quite consistent with our astronomical observations, even though it clashes with the thought that we are godless and making it on our own. (Davies, P.C .W .; "Cosmic Heresy?"

Among the many maverick items in his catalog are objects that seem physically related but have radically different redshifts. Examine for instance the illustration, which shows the large galaxy NGC 7603 (possessing a supposed recessional velocity of 8,700 km/sec) and its smaller companion at the end of the filament, which recedes at the much higher velocity of 16,900 km/sec. According to the Theory of the Expanding Universe, the greater the recessional velocity (as measured by the red or Doppler shift), the farther away the object is. But Arp's many examples of physically connected galaxies with wildly different redshifts suggest that some of the disparities in redshifts may actually be due to the related objects flying apart from each other. In the illustration, the small companion might have been "shot out" of its parent galaxy at high velocity by some unappreciated galactic gun.

One reads virtually nothing on the subject today, despite some encourageing developments. In a panel discussion at the University of Utah, J. Bockris stated that Japan has organized a fusion institute where more than 80 scientists are "rapidly moving forward to develop cold fusion." Bockris himself has achieved positive cold-fusion results in his lab at Texas A&M . Another panel member, R. Huggins from Stanford, who has also replicated Utah's cold fusion results, remarked that several other U.S . labs have achieved excess power levels of 10-30 watts/cc. (Anonymous; Access to Energy , p. 4, October, 1989. Cr. P.F . Young) Despite positive results like those mentioned above, a recent report in Nature, by scientists at Cal Tech and the University of California, states emphatically that they can find no excess heat, neutrons, gamma rays, tritium, or helium in their cold-fusion experiments.

... as if it were not there. A very, very few, however, are captured in huge, fluidfilled tanks built by physicists. These trapped ghostly particles tell tales we do not yet fathom. We have mentioned the solar-neutrino problem before (SF#46/84, for example). It is one of science's more perplexing and enduring mysteries. Even the most modern, sophisticated neutrino detectors count only about one-third the number of neutrinos that the sun "should" be sending in our direction -- according to our best theories on the nuclear reactions simmering away in the solar core. To this classical neutrino problem has been added the discovery that the solar neutrino flux varies in ways difficult to explain. P. Sturrock and G. Walther, at Stanford University, scrutinized 20 years of data from a detector deep in the Homestead Mine in South Dakota and find that the neutrino flux seems to peak every 21.3 days, varying as much as 30% to 100%. It may be that the sun's fusion "engine," long thought to run steadily and smoothly, sputters in a cyclic fashion? If an automobile engine did this, we would take it to the garage! (Holden, Constance; "More Neutrino Mystery," Science, 273:1663, 1996.) The problem deepens: The first 102 days of neutrino data from Japan's new Super-Kamiokande detector suggest that the solar neutrino flux is greater at night than during the day, and that it also varies during the year.

Just as the 150-million-year-old Archaeopteryx fossil is being reinstated as the earliest known bird after considerable controversy, along come two crowsize skeletons that are not only 75 million years older than Archaeopteryx but also more birdlike, according to the paleontologists who discovered them. The Washington, D.C .- based National Geographic Society, which funded the work, announced this week that Sankar Chatterjee and his colleagues at Texas Tech University in Lubbock found the 225-million-year-old fossils near Post, Tex." (Weisburd, S.; "Oldest Bird and Longest Dinosaur," Science News, 130:103, 1986.) Chatterjee has named the new fossil Protoavis. "Protoavis seems certain to reopen the long-running controversy on the evolution of birds. In particular whether the common ancestor of birds and dinosaurs was itself a dinosaur. Protoavis, from the late Triassic, appears at the time of the earliest dinosaurs, and if the identification is upheld it seems likely that it will be used to argue against the view of John Ostrom of Yale University that birds are descended from the dinosaurs. It also tends to confirm what many paleontologists have long suspected, that Archaeopteryx is not on the direct line to modern birds. It is in some ways more reptilian than Protoavis, and the period between the late Jurassic Archaeopteryx and the world-wide radiation of birds in ...

The conclusion of this highly theoretical paper is that, even in these "islands of hope," life and the order it requires cannot survive indefinitely if it is restricted to solid substances. But, ". .. it stands as a challenge for the future to find dematerialized modes of organization (based on dust clouds or an e- e+ plasma?) capable of self-replication. If radiant energy production continues without limit, there remains hope that life capable of using it forever can be created."

The universe of voles -- small, mouse-like rodents -- is one of odor. They communicate with one another and navigate through their world of grass and vegetation by laying down trails of scent-laden urine. The world of kestrels -- eaters of voles -- is one of sight. Now, voles are hard to see in the grass far below a hunting kestrel, but evolution has come to the aid of the kestrels by giving them the capability to see in the ultra-violet portion of the spectrum. Can it be only coincidence that the urine trails of the voles happen to absorb ultra-violet light strongly? Kestrels can see these trails as dark streaks in the grass below and zero in on their prey. Finnish scientists, led by E. Korpimaki at the University of Turku, have demonstrated the above ultraviolet connection by somehow acquiring enough vole urine to lay out artificial trails in voleless areas. Sure enough, hunting kestrels were attracted to the experimental site and searched and searched the artificial vole highways -- volelessly. (Aldous, Peter; "Vole's Urine Is Their Downfall," ...

Tifft, an astronomer at the University of Arizona, has maintained for some two decades that the redshifts of the galaxies do not fall on a smooth curve as one would expect. Instead, Tifft asserts, redshifts are bunched at intervals of 72 kilometers/second and at onehalf and one-third that value. Mainstream astronomers insist that redshifts be interpreted as Doppler shifts due to the expanding universe. Quantized redshifts just don't fit into this view of the cosmos, for they imply concentric shells of galaxies expanding away from a central point -- earth! Even though more recent redshift data have supported the notion of quantized redshifts, cosmologists find them undigestible, even pathogenic. But replication and non-replication are the essence of science, so B. Guthrie and W.M . Napier, at the Royal Observatory at Edinburgh, undertook another study. They selected 89 nearby spiral galaxies that had not been incorporated in any of the previous surveys. These galaxies had very accurately measured redshifts and were distributed all over the celestial sphere. "As expected, the galaxies' redshifts showed a smooth distribution. Clearly, no quantization was being introduced by the radio telescopes or the data reduction process. But after Guthrie and Napier corrected each redshift to account for the Earth's motion around the center of the Milky Way -- a different correction for each location in the sky -- out popped ...

For example, a recent issue of Discovering Archeology debunked them at great length and rather testily to boot. This broadside was followed by a devastating review of T.D . Dillehay's The Settlement of the Americas: A New Prehistory in the magazine Natural History. The reviewer for Natural History, A.C . Roosevelt, a respected anthropologist at the University of Illinois, targets the Cactus Hill site, in Virginia (SF#130). This dig, she says, is characterized by "inconsistent dates, vague stratigraphy, and inadequate artifact samples that disqualify them from scientific acceptance." Even Dillehay's monumental work at Monte Verde, Chile, does not survive the review unscathed. In fact, the claimed pre-Clovis sites, according to Roosevelt, do not yield sound, consistent radiocarbon dates earlier than 11,500 B.P . She will, however, entertain Bering Strait crossings as early as 12,000 B.P ., but not a microsecond earlier. (Roosevelt, Anna Curtenius; "Who's on First?" Natural History, 109:76, July-August 2000.)
