Halton Arp, an energetic opponent of the standard cosmological view, points out that quasars are socializing in disgracefully large numbers in one region of the sky. In the direction of the so-called Local Cluster of galaxies, between redshifts 1.2 -2 .5 , there are roughly four times as many quasars per unit volume as in the other parts of the sky. This unexpected clumping of quasars affects a region 1,3000 million light years in diameter and 4.875 million light years deep, a rather substantial chunk of the cosmos. Arp's discovery places astronomy in a no-win situation. Either the distribution of quasars is too clumpy for current theory or the redshift/distance law is wrong. Neither situation makes astronomers very happy. (Anonymous; "Quasars and Quasi Quasars," New Scientist, p. 20, May 17, 1984.) From Science Frontiers #34, JUL-AUG 1984 . 1984-2000 William R.

New varieties of the culprit -- called a calicivirus -- have since turned up in diverse hosts: whales, cats, snakes and even primates. To reach such a variety of hosts, they either jump from organism to organism, Smith proposes, or they escape from bubbles popping on the ocean surface, waft ashore and enter a food chain. If he is right, the seas may be a bottomless reservoir for viruses -- and our attempts to combat diseases on land may be nullified by legions of new strains waiting to come ashore.

Sepkoskiand and D. Raup, two researchers at the University of Chicago, have drawn up graphs showing the numbers of families of marine organisms that have vanished from the fossil rec ord over the eons. From this overview of manifest mass extinction emerged a puzzling and potentially profound pattern. Roughly every 26 million years over the last 250 million years, the number of extinctions jumped well above the background level. Some cyclic phenomenon seems to have been killing off life forms on a systematic basis. But no natural 26-million-year cycles are known although meteors and comets are favored causes of mass extinctions these days, they display no such cyclic period. (Simon, C.; "Pattern in Mass Extinctions," Science News, 124:212, 1983.) Comment. Instead of looking outward to astronomical catastrophism, perhaps we should look inward. The earth itself may undergo cyclic paroxysms; or life might undergo intrinsic phases of decline and rejuvenation. Periodic events in the evolutionary time scale. The 300-million-year cycle shown involves alternations between "icehouse" conditions (O ) and "greenhouse" conditions (G ). These may be due to changes in heat convention within the earth.

Few scientists have contemplated the possibility of life forms prospering at temperatures well beyond 100 .

It was obviously a highly advanced culture, technologically and socially. But it was dated at 400-800 AD; and for this period in South American history these accomplishments did not seem out of line. Recently, though, additional evidence of this civilization was discovered beneath a datable volcanic ash. The new dates for this civilization are 600-1 ,500 BC, putting it about 1,000 years ahead of Maya and Inca achievements. The "digs" show further that this culture was frequently beset by devastating outbursts of volcanic activity, which often rendered large areas of land uninhabitable. Rather than suppressing this remarkable culture, Donald Lathrap, a University of Illinois archeologist, says: "Those disasters pushed people from the region and led to upward leaps in social evolution..."

An equivalent situation would prevail in the brain if all sensory pathways and cells had fixed duties and memories to handle. If the portion of the brain dedicated to speech were damaged, as in a stroke, it could never repair itself. This dogma is now being challenged. A pertinent line of brain research is now underway at the Coleman Laboratory of the University of California in San Francisco, where Michael Merzenich and his associates are studying the brains of monkeys. "Merzenich's findings challenge a prevailing notion that most sensory pathways in the nervous system are 'fixed' or 'hardwired' by the maturation of anatomic connections, either just before or soon after birth. They also address the puzzling question of what forces may be at work when stroke victims partly recover. Do 'redundant copies' of skills exist outside the damaged regions, or is physical damage within the brain repaired over time? Or can old skills be newly established in different, undamaged brain regions." Apparently the brain should really be compared with a reprogrammable computer. Perhaps the brain even stores duplicates of critical "programs"; i.e ., skills. Merzenich's findings go even farther.

Well, we don't have any more contradicting data (of which there is plenty), but we do have: (1 ) A new theory which shows how noncosmological redshifts can occur; and (2 ) Laboratory demonstrations of "spectral noninvariance" that show how a non-Doppler component can be added to light's redshift. The physicist behind this new research is E. Wolf, at the University of Rochester. His theoretical work was re-ported in the March 3l, 1986, issue of Physical Review Letters. There he showed how quasars and so-called "superluminary" astronomical sources might emit light with a spectrum that evolves as it travels through space. Scientists have always assumed that once light left its source its spectrum remained unchanged. But Wolf shows how spectral changes are "sort of coded into the light due to correlations in the source." Meanwhile, two of Wolf's colleagues have backed up his theory in the lab. The consequences of Wolf's work would in effect shrink the universe, because objects would not be as far away as we now calculate from their redshifts. The size of the universe might contract ...

R. Lynds, of Kitt Peak National Observatory, estimates that the arcs are as luminous as 100 billion suns. The nice circularity of the arcs is perplexing; and it is stated that nothing like them has been reported before. The arcs might be incandescent gas, but many astronomers opt instead for swaths of bright young stars. Spectroscopic tests will decide this point. It has been difficult to conceive of an origin for the arcs. Are they blast waves or the results of tidal action between galaxies? No one knows, for all suggestions seem flawed.

Zwicky proposed that the redshifts astronomers observed in the spectra of celestial objects might not be due to universal expansion but rather to "tired light." In other words, the wavelengths of the photons entering our telescopes are redshifted because they have lost energy through interactions with matter en route to earth. The "tired light" theory was eclipsed by the esthetically appealing concepts of the Big Bang and Expanding Universe. But not everyone has forgotten Zwicky's tired light. P. LaViolette has: ". .. compared the tired light cosmology to the standard model of an expanding universe on four different observational tests and has found that on each one the tired-light hypothesis was superior.

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.

Perhaps there are inhomogeneities on a different, more basic level -- matter vs. antimatter. According to one popular theory, the universe began with equal amounts of matter and antimatter. If so, where did all the antimatter go? We assume we observe a universe that is virtually 100% matter. Of course, we cannot really tell for certain because an antimatter galaxy would appear to us just like a galaxy composed of ordinary matter. The only clues revealing substantial pockets of antimatter would be the annihilation radiation produced where matter and antimatter regions rubbed against one another. The two types of matter always annihilate one another in bursts of very distinctive radiation. Well, there seems to be at least one region of antimatter near the center of our galaxy. The HEOS3 satellite and ballon-borne instruments have pinpointed a source of 511 kev gamma rays that can come only from a spot where electrons and positrons are mutually annihilating each other. (The positrons are antimat-ter analogs of electrons.) This region of mutual destruction is about 1013 kilometers across. Is it a pocket of antimatter left over after the Big Bang that a sea of surrounding matter is finally wiping out, or is it newly created antimatter in the vicinity of a black hole? No one knows. The mystery has deepened with the discovery that the intensity of the annihilation radiation varies with ...

Since our terrestrial neutrino detectors register only electron-neutrinos, we may really be seeing only a fraction of the total number of neutrinos being emitted by the sun.

The answer might be YES; and then all of astronomy and our entire view of the universe and its history would have to be reformulated. (Tifft, William G., and Cocke, W. John; "Quantized Galaxy Redshifts," Sky and Telescope, 73:19, 1987.) Redshift differences for double galaxies. Instead of following the expected distribution (dotted line), they tend to fall into bins separated by 72-km/sec. From Science Frontiers #50, MAR-APR 1987 . 1987-2000 William R. Corliss ...

In early 1976, a tagged individual from Chaska, Minnesota, was indeed found among a huge cluster in Mexico. Also, a few butterflies tagged in the northern states have turned up in Texas, well on their way to Mexico. (Urquhart, Fred A.; "Found at Last: The Monarch's Winter Home," National Geographic Magazine, August 1976. Cr. B. Ickes) Comment. So, it seems that A.M .

... Issues This Issue Sourcebook Project Sourcebook Subjects The kensington stone: a mystery not solved It is safe to say that the great majority of professional archeologists consider the Kensington Stone, with its runic inscription, to be a hoax. E. Wahlgren's 1958 book bears the title: The Kensington Stone: A Mystery Solved. This title reflects the professional attitude, although not the disdain, even contempt, with which academics now view this controversial artifact. Two major challenges to the authenticity of the Kensington Stone are: (1 ) Its use of Arabic number placement: that is, decimal placement, and (2 ) Its use of the symbol for 10. Professional archeologists and epigraphers maintain that genuine runic inscriptions did not use these Arabic innovations. In the present article, R. Nielsen, University of Denmark, demonstrates with actual, well-established runic inscriptions that the above criticisms are without foundation. Such notation and convention were employed. In fact, the use of Arabic innovations actually supports the authenticity of the Kensington Stone. (Nielsen, Richard; "The Arabic Numbering System on the Kensington Rune Stone," Epigraphic Society, Occasional Publications, 15:47, 1986.) Reference.

... Sourcebook Subjects Monarch Migration An Illusion "The epic autumn migration of the eastern monarch butterfly to wintering grounds in Mexico, where millions cluster on trees in semi-dormancy to await spring, has become known as one of the standard 'wonders of nature' in the decade since the Mexican winter clusters were found." There are, however, some flies in this ointment: Monarchs tagged in the north have never been found in the Mexican clusters. Fall-fattened monarchs can store only enough energy for a flight of about 200 miles -- far too short, unless they refuel along the way (no one knows if they do or not); and The monarchs seen in Mexico are almost always in pristine condition and show no wing wear or tattering. A.M . Wenner, University of California at Santa Barbara, thinks that the "appearance" of mass migration reported frequently from many locales may just be due to a curious fall habit of the monarchs. It seems that widely scattered individuals begin to fly into the wind, and the wind concentrates and channels them to local roosts where they spend the winter. In other words, there is no long distance migration at all. (Rensberger, Boyce; Washington Post, September 15, 1986. Cr. J. Judge) From Science Frontiers #49, JAN-FEB 1987 . 1987-2000 William R.

... 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.

... Archaeology sets the Nazca lines in perspective and adds some new observations. First, Aveni deflates their mystery a bit. You do not have to be in an airplane to appreciate the lines; most can be viewed from ground level, even better from nearby foothills. Although there are some 1,300 kilometers of lines and about 300 geometric figures, their construction did not really involve much labor or special engineering skills. Even so, the Nazca lines are remarkable, and we really do not know for certain why they were etched on the Peruvian pampa. In his early research on the Nazca lines, Aveni noted their strong similarity to the ceque system of 41 imaginary lines radiating outwards from the Inca's Temple of the Sun, at Cuzco -- the "navel" of the Inca universe. ". .. the ceque system was a highly ordered hierarchical cosmographical map, a mnemonic scheme that incorporated virtually all important matters connected with the Inca world view." Could the Nazca lines have been a forerunner of the ceque system? Aveni also noticed that the Nazca lines and geometrical figures were closely related to watercourses. Also, many of the lines definitely functioned as footpaths. It was also apparent that the animal figures, which were laid down much earlier than the line systems, were not related conceptually to the line scheme. Aveni concluded: ". .. whatever the final answer may be to the mystery of the Nazca lines, this much is certain: the pampa is not a confused and meaningless maze of lines, and it was no more intended to be viewed ...
