As readers of Science Frontiers have long been aware, the New World was not new to many ancient voyagers. A review of the Conference in the New York Times gave wide exposure to some of these controverted pre-Columbian contacts: 5000-year-old pottery found in coastal Peru bears an uncanny resemblance to pottery made in Japan during the same period. How could the Japanese have reached Peru circa 3000 BC? Easy! Storms could have blown fishermen into the trans-Pacific current. (See "Current Treads" item under GEOPHYSICS.) The Zuni Indians of New Mexico may have been influenced by Japanese voyagers in the Thirteenth Century, as suggested by their distinctive blood chemistry, language, and culture. 700-year-old temple art from India reveals detailed depictions of ears of corn, which was supposedly unknown outside the Americas until after Columbus. Jewish refugees from the Roman Empire may have somehow reached eastern Tennessee, if the famous Bat Creek Stone really bears an ancient Hebrew inscription. The grave in which the stone was found has been carbon-dated between 32 and 769 AD. (Wilford, John Noble; "Case for Other Pre-Columbian Voyagers," New York Times , July 7, 1992 ...

Science Frontiers ONLINE No. 4: July 1978 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects A New Cosmic Heresy Often the simplest of observations will have the most profound consequences. 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?"

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.

... One's first inclination is to attribute such detonations to supersonic aircraft and missles, but the U.S . military immediately denied they were to blame. Seismic noises come to mind next, but the frequent failure to register the events on seismographs suggested an atmospheric phenomenon. The National Enquirer (January 24, 1978) rather predictably linked the booms to UFOs. In the federal government, the Naval Research Laboratory (NRL) was assigned the task of tracking down the booms. In March, NRL reported that all of the 183 detonations they investigated were due to supersonic aircraft. That seemed to end the matter -- just as the Condon Report signalled the demise of UFOs!! The booms had an interesting side effect: they triggered urgent requests for the two Strange Phenomena sourcebooks from several universities, think-tanks, and intelligence agencies. There may be more to this than meets the ear. For more information, see Walter Sullivan's articles in the new York Times of January 13 and 19, 1978.

In February, reports of this type increased markedly, including observations of general restlessness and agitation of the larger animals, such as cows and horses. Rats now appeared as if drunk. Chickens refused to enter their coops and geese frequently took to flight. Chinese scientists seem convinced that such animals behavior might help predict some of the larger earthquakes.

Two amusing examples are: The size of a planet is roughly the geometric mean of the size of the universe and the size of the atom; and The mass of man is the geometric mean of the mass of a planet and the mass of the proton. Less hilarious is the observation that the age of the universe is of the order of the quotient of the electron time scale and the gravitational fine structure constant; and that only at the present time are physical conditions in the universe favorable to the existence of life-as-we-know-it! The surprising number of coincidences that have been identified suggests that we exist and are aware of the universe around us only when certain coincidences prevail among physical constants.

The two separating membranes will dissove and the cell contents will mix. The once-independent and widely different cell nuclei will fuse, forming a single hybrid cell with a common membrane. Even more astonishing, this totally new biological entity will often divide and produce an endless line of the new hybrid. As might be expected, some hybrids do not remain true and revert to one or the other of the original species. Although cell fusion has been observed only under laboratory conditions, it seems to represent a near-universal cell phenomenon that might be realized rarely under natural conditions. The implications for the history of life are far-reaching. For example, the mitochondria in human cells that help our bodies use oxygen to obtain energy may well be descendants of bacteria that once fused with primitive cells. The same may be true for the chloroplasts in plant cells. (Thomas, Lewis; "Cell Fusion: Does It Represent a Universal Urge to 'Join Up'?" Science Digest, 86:52, December 1979.) Comment.

Unfortunately for the Expanding Universe, some redshift measurements indicate a quadratic rather than linear relationship between redshift and distance. I.E . Segal's chronometric theory of the cosmos, however, does predict a quadratic relationship. In Segal's theory redshifts are due to the gravitational slowing of light rather than any gereral expansion of the universe. Even if most astrophysicists are finally persuaded that the quadratic relationship is real, they will be loath to abandon the philosophically appealing Expanding Universe. Not only is the Expanding Universe consistent with Relativity but it states unequivocally that the earth (and man) does not occupy a preferred place in the universe.

In recent years, the so-called Hubble Constant has been used to determine the distances of the farthest observable galaxies and, by assuming that they are near the periphery of the expanding universe, obtaining the age of the cosmos by dividing distance by the speed of light. Until this current challenge, the age of the universe was generally taken as about 20 billion years. The "old" Hubble Constant, however, was determined from the measurements of the distances to rather close galaxies and then assuming that the Constant thus derived held for the entire universe. The new yardstick reaches farther out into space. It is based upon the observation that the broadening of galaxy's 21-centimeter radio emission depends upon its rate of rotation, plus the belief that the rate of rotation is proportional to its brightness! This "new" Hubble Constant is 95 kilometers/second/ megaparsec, which translates into an age of only 10 billion years for the universe. Both the 10-billion-year and 20billion-year camps claim strong supporting evidence for themselves and also point to serious difficulties in the opposing method. The stage is thus set for a delightful controversy. (Hartline, Beverly Karplus; "Double Hubble: Age in Trouble," Science, 207: 167, 1979.) ...

The Big Bang scenario allows for uniform, universal expansion but certainly no general rotation. P. Birch, the author of this article, puts his finger on the problem in his abstract: "This would have drastic cosmological consequences, since it would violate Mach's principle and the widely held assumption of large-scale isotropy." (Birch, P., "Is the Universe Rotating?" Nature, 298:45l, 1982.) Comment.

One of its companions is a galaxy so dense that it appears to be a star. This compact object sports a circular shadow and seems to be silhouetted against the central galaxy NGC-1199. Arp's analysis of the absorption ring seems to prove that the compact galaxy is in front of the central galaxy. This would normally be permissible, but here the central galaxy has a redshift of 2,600 km/sec compared to 13,300 km/sec for the galaxy in front of it. This is astounding because the farther away an object is, the greater its redshift is supposed to be. (Arp, Halton M.; "NGC-ll99," Astronomy, 6:15, September 1978.) Comment.

Was the venerable Law of Conservation of Mass/Energy violated? Big Bangers loftily dismiss such questions as "nonsense." Narlikar follows with some observational problems of the Big Bang: There seem to be objects in the universe that are older than the Big Bang age of the universe (9 -13 billion years); Quasar redshifts used to support the Big Bang theory may arise from the general expansion of the universe; The microwave background radiation of 3 K, which was gleefully embraced by Big Bangers as an echo of their version of creation, is actually of the same energy density as starlight, cosmic rays, etc., and need not have anything to do with the Big Bang; and The Big Bang Theory and General Relativity assume a constant G (the gravitational constant), but some recent lunar orbit measurements suggest that G is slowly decreasing!

(His experiment was inconclusive.) Today, in most scientific edu-cation and practice, it is customary to assume that mathematics is not only a faithful mirror of the real world but that it can actually lead us to new insights into reality. Unfortunately, two facts mar this idealistic picture. Mathematics itself contains contradictions and does not have a solid foundation; that is, it is "impure." Some portions of reality seem to confound mathematics; for example, Einstein found Riemannian geometry and tensor analysis imperfect for formulating the Theory of Relativity. Despite this disappointment, Einstein maintained his belief that God does not play dice with the universe. Some more recent scientists suggest that God not only plays dice but throws them where they cannot be seen! Despite the acknowledged deficiencies, it is clearly more than a stroke of luck that mathematics describes so much of reality so accurately. And here is the spooky part of the whole business. In formulating their web of logic, mathematicians make many more or less "artistic" decisions that are colored by reality and their expectations of reality. To illustrate, "symmetry" is a human passion that reality may disdain.

Tipler published a comment in Physics Today entitled, "Extraterrestrial Beings Do Not Exist." A key element of his argument was that the first intelligent civilization would inevitably colonize the entire universe with themselves or their self-reproducing (von Neumann) machines. Since we can detect neither kind of colonist, we must be the first and only intelligent civilization. Essentially Tipler was criticizing the prevailing notion that, from a statistical point of view, there must be many other civilizations among the numberless stars and galaxies. Tipler's thoughts evoked a richly provocative group of letters, some of which were published in the March 1982 issue of Physics Today along with a closely related article by Ornstein. Ornstein tackled the problem of estimating the probability that intelligent life would evolve on other planets from a biologist's perspective. Whereas some physical scientists have set this probability at about 1.0 , Ornstein inclines toward 10-9 , believing that intelligent life is probably unique to the earth.

Jeffries' analyses seem to indicate that the genes now coding for these hemoglobin chains are almost identical to those existing in human ancestors some 500 million years ago. Two curious facts have cropped up, however. First, about 200 million years ago, these genes were modified very slightly and relocated to entirely different chromosomes. Second, 95% of the DNA associated with these genes is "junk" -- with no known use. Why did nature conserve junk for 500 million years?

Yet, this boy has virtually no brain; his cortex measures only a millimeter or so thick compared to the normal 4.5 centimeters. Although the deeper brain structures may carry on much of the body's work, the cortex is supposed to be a late evolutionary development that gave humans their vaunted mental powers and superiority over the other animals. If the cortex can be removed with little mental impairment, what is it for in the first place? (Lewin, Roger; "Is Your Brain Really Necessary?" Science, 210:1232, 1980.) Comment.

In fact, more recent experiments have served only to accentuate the anomaly. Researchers at Stanford University have been magnetically suspending superconducting niobium spheres in a modern version of Millikan's oil-drop experiment. With the niobium spheres thus suspended, their net electrical charges can be measured. The trouble is that several of the spheres have fractional electrical charges -- + 1/3 or -1 /3 electronic charges. For decades the charge on the electron was supposed to be the basic, indivisible natural unit of electrical charge. In 1964, however, theorists began muddying the waters with talk of new fundamental constituents of matter called quarks, which could possess 1/3 or 2/3 electron charges. No one really expected that quarks, if they existed at all, would be floating around free. But the niobium balls tell us that not only are quarks free but that we could have detected them with relatively simple experiments decades ago if we had not been so blinded by the idea of integral electronic charges.

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.

Doppler measurements of galaxy rotations made by Vera C.

Astronomers suppose that this anomalous rotation may be due to halos of undetected burntout stars and/or gas fringing the galaxies.

Kirshner et al carefully measured galactic redshifts in three widely separated regions of the sky and found almost no galaxies in the redshift velocity interval 12,000 to 18,000 km/sec in all three areas. One interpretation of this huge gap is that the initial post-Big-Bang distribution of matter in the universe was unexpectedly lumpy.

If these two ratios are truly equal, then G must decrease with time. Beyond the unstable feeling one gets, there is nothing in physics or cosmology to discourage a belief in time-varying gravity. Indeed, some as-tronomical data weakly support the idea. It is geophysics, though, where one finds strong evidence. Measurements of the decreasing length of the day and the expansion of the earth give about the same value for a decreasing G -- after other contributing factors have been eliminated.

The reasons are several: The observed universe is extremely homogeneous, even though theory says that distant parts of the universe could never have been causally connected; No satisfactory explanation exists for the density fluctuations that had to occur for galaxies to be formed; and The universe seems to be flat, not curved, and the Big Bang does not explain why. Paul Steinhardt and Andreas Al-brecht, at the University of Pennsylvania, have developed a radically different Big Bang -- a two-stage one, with hot and super-cooled states. The three objections listed above are neatly disposed of in the new version, but at the cost of a radically new view of the cosmos. The "new" universe is about 10100 times as big as the 12 billion light years assigned to the cozy universe we used to know -- and it is presumably correspondingly older.

Perhaps the Big Bang is just a facade that diverts us from theories that better explain the observed characteristics of the universe. A trio of American and British astron omers (B .J . Carr, J.R . Bond, W.D . Arnett) are exploring the possibility that the cosmos began with a generation of very massive stars rather than the debris of the Big Bang. These huge stars would have had masses 100 or so times that of the sun. By virtue of the much higher pressures and temperatures at their cores, they would have burnt up their fuel inventories much faster than sun-sized stars. Thus they would have burnt themselves out long ago, probably surviving as black holes. Such an ancient generation of massive stars can explain four puzzling features of the universe: (1 ) The amount and character of the background microwave radiation. (2 ) The identity of the "missing mass" needed to hold the universe together (i .e ., the relict black holes). (3 ) The primordial abundance of helium.

This string exists only in closed loops of infinite strands. Such string in loop form could have seeded galaxies and even black holes of solar mass. But these are not the major reasons why astronomers like the string hypothesis. It turns out that this bizarre string can tie the universe together gravitationally; that is, provide the long-sought 'missing mass.' The so-called 'missing-mass problem' is two-fold: Astronomers cannot see, with eye and instrument, enough mass to keep the universe from expanding indefinitely.

This paper calls attention to several of these intimations of a real world beyond the natural order. Examples are the complex state functions in configuration space of quantum mechanics, the singularity at the birth of the universe, the anthropic principle, the role of chance in evolution, and the unaccountable fruit fulness of mathematics for physics. None of these examples touch on the existence or activity of God, but they do suggest that external reality may be much richer than the natural world which it is the task of physics to describe." Pollard then elaborates: Example 1. Quantum mechanics, a mathematical formulation of reality, has been extraordinarily successful in describing and predicting many things in the microscopic world. Pollard notes that quantum mechanics contains no hint of God per se and possesses no numinous quality, but its great complexity and multidimensionality provide evidence for "the reality of the transcendent order in which the natural universe is embedded."

Instead of developing celestial mechanics based on gravitation and laws of motion, as we have done, they were content with numerical algorithms; that is, ways of computing a desired result. Their astonishingly accurate predictions of Venus, solar eclipses, and other astronomical phenomena evolved from cycles of numbers advancing each day like interlocking gear teeth.

They give additional examples of order arising from disorder in astronomy (spiral galaxies, superclusters), from chemistry (Belousav-Zhabotinsky reactions), and biology (embryonic development). Again and again, they ask why order persists on increasing when the Second Law of Thermodynamics seems to demand more disorder. Throughout the article, the Tuckers employ the card-shuffling analogy.

"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.

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.

This smacks of scifi tales of electrolife and Hoyle's Black Cloud. From Science Frontiers #24, NOV-DEC 1982 . 1982-2000 William R. Corliss ...

"On January 14, 1983, I observed a perfectly round black orb crossing the sun. It started at 17h 54m 23s Universal Time and ended at 17h 54m 26s Universal Time and lasted three seconds. On a projected solar disk with a diameter of 18 centimetres, the object had a diameter of one-half centimeter." (Lohvinenko, Todd; "A Mysterious Object," Royal Astronomical Society of Canada, National Newsletter, 77:L19, 1983.) Comment. This object traveled too fast to be an intramercurial planet; too slowly for a meteor. Path taken by the black spot cross the face of sun.

Science Frontiers ONLINE No. 35: Sep-Oct 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Immune System As A Sensory Organ John Maddox, the editor of Nature, has written a remarkable editorial on psychoimmunology; that is, the science of the brain's effects on the body's immune system. It is basically a running commentary on new discoveries that are helping us to understand this poorly appreciated relationship. Maddox begins by mentioning the 20-plus-year collection compiled by Professor G.W . Brown, University of London, of life-events that affect the health of outwardly normal people. Typical life-events are the death of a spouse, imprisonment, personal bankruptcy, etc. Everyone seems to recognize -- if only through anecdotes -- that mental states affect health, but how this brain-body link is maintained is hard to pin down. D. Maclean and S. Reichlin (Psychoneuroimmunology, 12: 475, 1981.) have reviewd some of the possible connections. One potential link is through the interaction of the hypothalamus on the pituitary. The pituitary is a source of materials that influence the immune system. Maddox lists several specific candidates, and then observes: "The more radical psychoimmunologists talk as if there is no state of mind which is not faithfully reflected by a state of the immune system." So far, not too radical! But then Maddox comes to an article by J.E . Blalock, University of Texas (Journal of Immunology, 132: ...

... Science Frontiers ONLINE No. 37: Jan-Feb 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Why aren't the martian craters worn down?The preceding, almost-Lowellian vision of a watery Mars is quite different from what the Mariner and Viking spacecraft tell us about the planet's present condition. Wind rather than water is now the main erosional force. The sand dunes and drifts, the wind-shadows behind rocks, and the sand-blasted surfaces all attest to the desertification of Mars. Ronald Greeley, of Arizona State University, and his colleagues have simulated Martian winds in a special wind tunnel at NASA's Ames Research Center. Using spacecraft-measured wind velocities and patterns, they tried to duplicate the Martian erosional environment. The results were a surprise. They implied that the Martian surface should be worn down by wind-driven sand and dust at rates up to 2 centimeters per century. But at that rate, the Martian craters, which are estimated to be hundreds of millions of years old, would have been worn level long ago. The researchers are now wondering what is wrong with their simulation. They venture that the Martian sand may not be "normal," or perhaps the eroding particles do not travel as fast as they figured. (Anonymous; "The Windblown Planet Mars," Sky and Telescope, 68:507, 1984.) Comment. Another interpretation is that Mars has not been desert-like for as long as presently believed. Reference. The subject of ...

Science Frontiers ONLINE No. 35: Sep-Oct 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Mind Before Life For some years S.W . Fox, at the Institute for Molecular and Cellular Evolution, University of Miami, has been experimenting with possible precursors of life. So-called "microspheres" are hot items in Coral Gables these days. Fox and his colleagues make microspheres by preparing a heated stew of various amino acids. These amino acids form long polymer chains spontaneously. Then, when water is added and the mixture reheated (or processed in some other way), the polymers organize themselves, again spontaneously, into spheres a few microns in diameter. Each sphere consists of a two-layer membrane with residual material trapped inside. Although thicker, the microsphere membrane is very similar to the lipid bi-layer enclosing normal living cells. The relatively stable microspheres could, in theory, have formed sheltered environments for the evolution of the more complicated parts of living cells. The microspheres absorb sunlight and, with the addition of this energy, display some of the electrical characteristics of biological neurons, like those in the brain. The implication is that some components of "mind" may have existed in the very earliest life forms. (Peterson, Ivars; "Microsphere Excitement," Science News, 125:408, 1984.) Comment. Two comments here: First, the word "spontaneous" is customarily employed when describing how atoms unite to form molecules and molecules combine into polymers, which then gather ...
