Green St. Elmo's fire was glowing on the aerials. "At about 2310 it was also noted that the lever extending about 18 cm over the ship's starboard bridge wing to position a deck light was also radiating light. This light was a pale violet glow extending in 'spokes' of 10 cm in length from the round end of the lever which was about 3 cm in diameter. "There were six individual and uniform spokes shot through with brighter purple and white bolts resembling lightning. Over the noise of the wind a sharp crackling and hissing sound could be heard coming from the phenomenon. "The seaman was called to have a look at the light, he attempted to touch it but the light receded as his finger approached within 3 cm of it.

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.

No noise was heard and it looked like an artificial satellite, except for the direction of its motion. Its brightness, color and angular velocity reminded me of the old Echo artificial satellite from the 1960s. The object disappeared from sight during the few seconds it took me to call two persons to participate in the observation. It was not apparent how the object had disappeared from view since there were no sources of obscuration evident. Having become puzzled by this observation I continued watching that same region of sky from time to time. "About fifteen minutes later (22:45 local time) and more or less in the same region where the bright light had been observed I spotted a faint luminous object moving slowly toward the zenith. During the first few seconds of observation it had the appearance of a luminous thread, oriented perpendicular to its direction of motion. However, as it approached the zenith, I could see that it was in fact a group of at least 30 lights distributed in a broad, symmetrical V-configuration, reminiscent of a boomerang. Three members of my family who were with me also observed the group of lights. "Each individual light of the group looked like a star of third or fourth magnitude; the color was a pale white similar to a neon light, with a slight tint of yellow.

Of course, we recognize that whales and other cetaceans also seem to "talk" to one another, and that other animals employ their sense of smell for relaying messages. But most of us do not realize that lowly fireflies congregate to communicate en masse, with untold thousands of individuals cooperating in huge synchronized light displays. In reading some of the descriptions of these great natural phenomena, one recalls the light displays used to communicate with the aliens in the movie Close Encounters of the Third Kind . J. Buck has been studying flashing fireflies for over half a century. In fact, his first review paper was published in 1938. Buck has now brought that paper up to date in the current Quarterly Review of Biology with a 24page contribution. It is difficult to do justice to this impressive work in a newsletter. Our readers will have to be satisfied with a mere two paragraphs, in which Buck summarizes some of the incredible synchronies. "More than three centuries later Porter observed a very different behavior in far southwestern Indiana in which, from the ends of a long row of tall riverbank trees, synchronized flashes '. .. began moving toward each other, met at the middle, crossed and traveled to the ends, as when two pebbles are dropped simultaneously into the ends of a long narrow tank of water ...

Flashes of light were seen in the bow wave and the ship's wake, appearing to be both on the surface and slightly below. This type of display is rather common, but another, much rarer phenomenon was also present: In 1880 off the Malabar Coast of India, a vessel was engulfed in great waves of light floating above the sea. "At the same time as the above form of bioluminescence, there seemed to be a second type but it was difficult to pinpoint the source. The effect was that the atmosphere around the ship and extending to the horizon had some form of faint white illumination not provided by the light in the water, which was black apart from the previously described flashes. On the other hand, there was no obvious source in the sky either, which although virtually cloudless was very dark, and certainly darker than the atmosphere at the level of the ship. The only conclusion that the observers could come to was that this was a faint example of (to quote The Marine Observer's Handbook ), 'luminescence in the air a few feet above the sea surface when there is no light in the water'. This form lasted for about 30 minutes, whereas the bright flashes continued for ...

These are the rays that penetrate to the greatest depths in the sea. This adaptation to blue light means that deepsea fish have evolved visual pigments different from those of surface fish and land animals. Visual pigments are complex chemical compounds, and one must suppose that many, many random mutations took place before deepsea fish were able to manufacture visual pigments different from their relatives living near the surface. (Or did deepsea fish come first?) But there is more to this story. Many dwellers in the black abysses generate their own light. They sport bioluminescent organs so they can be seen by others of their own species and, in addition, illuminate prey for easier capture. In another remarkable example of evolutionary convergence, these bioluminescent organs emit light spectrally matching the eye sensitivity of deepsea fish! So far, though, this story is not any more amazing that many others woven into evolution's fabric. But suppose that a deviant species of deepsea fish upset this cosy status quo by evolving visual pigment and bioluminescent organs operating in a part of the electromagnetic spectrum that other deepsea fish could not perceive. It would be as if this species had radar but the others did not! Well, three genera of dragon fish do ...

Most Bigfoot reports come from the Pacific Northwest. Nevertheless, enough Bigfoot sightings, hearings, and footprints have accumulated in the Rockies for the Denver Post to print a lengthy review of the Bigfoot phenomenon. The article identifies three Colorado hotspots: (1 ) Leadville, where the Little Creek Monster was reported as early as the 1880s; (2 ) the southern San Juan Mountains; and (3 ) Pike National Forest.

The Java Sea. "At 0210 LMT I witnessed the start of a bioluminescent display. My first impression was that the ship was being 'attacked' on all sides from different directions by pulsing light-bands. A dull 'strobe-light' effect flashed through a mist, giving the bands a dirty white to gray colouration which was not a 'smooth' colour, but rather grainy in appearance. The bands were about 2 m wide and about 2 m apart and moving at speed. At first it was difficult to discern whether or not the bands were in the water or just above the surface, as no form of reflection or distortion was visible off the hull. In the end, I decided that the effect must be waterbourne if only because nothing was visible in the vessel's wake. "The most intense activity was observed on the starboard side of the ship where the phenomenon appeared to stretch as far as the horizon. At this stage, it did not appear localized, just a mass of high-speed interacting bands of light. The effect is shown in the first sketch. As is usual on an 'all aft' ship, you become 'deaf' to the constant background noises, but I gradually became aware that the pulses of light seemed to match those of the main engine's throb, that is, about two per ...

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 ...

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 ...

When a recent photo of the "Face" taken by the Mars Global Surveyor (MGS) was published far and wide in the science press, we thought the matter had finally been settled. The photo showed a strange hill obviously sculpted by natural forces. No question about it; there was not a soupcon of artificiality. But it now seems that if you look at the "Face" at other lighting angles and process the same data in different ways, the "Face" reappears looking more artificial than ever. T. Van Flandern elaborates: The MGS spacecraft took a high resolution photo of the "Face on Mars" in April 1998. That image suffered from four handicaps: a low viewing angle; a low sun angle from the direction of under the "chin"; an almost complete lack of contrast; and enough cloudiness to scatter most of the light and eliminate shadows. To add to these difficult circumstances, JPL-MIPL [Jet Propulsion Laboratory-Mission Image Processing Laboratory] personnel, apparently judging that the controversy over artificiality would not be ended when the actual photo was released, processed the image through two filters having the effect of flattening and suppressing image details. This step is documented at a JPL web site. Here we ...

The curious glows recently remarked at these vents (SF#87) have stimulated much speculation as to the potential role of these glows in the origin of life: "The history of hydrothermal activity predates the origin of life, and light in the deep sea has been a continuous phenomenon on a geological time scale and may have served either as a seed or refugium for the evolution of biological photochemical reactions or adaptations."

A famous flare example was observed and reported in 1900 by A.E . Douglass, at the Lowell Observaory. The popular press quickly announced that the Martians were signalling us. Actually, this assumption was quite understandable because in those days the newly discovered Martian "canals" were in everyone's thoughts. Most scientists, however, rejected the signal notion preferring to attibute the flare to the specular reflection of sunlight from snowy peaks on Mars. But they were wrong, too. Close-up inspection by modern spacecraft has revealed no snowy peaks or large bodies of water on Mars that might mirror the sun. But another possibility has now come to the fore. The Martian flares could be reflections of sunlight from flat, hexagonal crystals of water ice in the thin Martian clouds; the same crystals that create some of the solar halos and sun dogs seen on earth. That this sort of specular reflection does occur was demonstrated on June 7, 2001, when a flare was actually photographed in the area of Edom Promontorium. The photography was possible because scientists had been watching this spot intently -- with cameras at the ready -- because a well-observed flare had occurred at this location in 1954, and ...

Then skeptical scientists like Hayden and Beckmann, will rest easier. But suppose the east and west velocities of light are different? Then Special Relativity would collapse.

Fairall has reported an "impossible" physical situation -- a strong scientific anomaly. It seems that a Seyfert galaxy (a very low-luminosity quasar) emits forbidden spectral lines that vary in intensity about every 30 minutes. It is not the "forbidden" character of the spectral likes that disturb the astronomers. (" Forbidden" simply means "improbable" in spectroscopy!) Rather, it is the half-hour variations that pose the dilemma. This is because most astronomers are convinced that the said forbidden lines are emitted by regions of the quasar that are 100-10,000 light years across. A disturbance or physical change leading to a variation in intensity, even travelling at the speed of light, could not begin to move across this huge region in half an hour. Yet, the changes in intensity seem to be there, inferring a physical change that travels perhaps a million times faster than physics permits. Variations in intensity decades long would be acceptable, but half an hour is out-of-the-question!

"The bottom of the rim was about 20 feet off the ground, and had doubtless a few moments before destroyed our house as it passed. The interior of the funnel was hollow; the rim itself appearing to be not over 10 feet in thickness and, owing possibly to the light within the funnel, appeared perfectly opaque. Its inside was so slick and even that it resembled the interior of a glazed standpipe. The rim had another motion which I was, for a moment, too dazzled to grasp. Presently I did. The whole thing was rotating, shooting past from right to left with incredible velocity. "I lay back on my left elbow, to afford the baby better protection, and looked up.

A group of researchers, led by oceanographers from the University of Washington, detected faint light during an expedition to the Juan de Fuca Ridge. The ridge and the vents, 300 km off the coast of British Columbia, follow an underwater fault formed by the junction of the Juan de Fuca and the Pacific tectonic plates...John Delaney, leader of the expedition, described the glow as a 'flame-like light' that seems to emanate from the super-heated water emerging from the thermal vents, 2200 meters below the surface...'The source of the light is still unclear,' said Joe Cann, a geologist from the University of Newcastle in Britain. The scientists suspect that the water itself is glowing." The water temperature is so high -- 350 C -- that bioluminescence is unlikely. The presence of the glow does, however, imply that photosynthesis is still possible in these sunless depths. Life forms do congregate around these vents. A curious shrimp found in the area where the glow was noted is eyeless but does possess photoreceptors on its back!

My wife and her mother were sitting in the yard with me and they saw them also.

About 3:00 A.M ., two young women were driving in a semi-rural area. Fog made visibility poor. It began to rain -- a brown jelly-like slime that smeared the windshield. A rotten-egg odor pervaded the area. The car engine stopped, and the two began to walk to find assistance. After 50 yards, they encountered millions of small rays of "lightning" flashing everywhere. They were 2-3 feet long and reached high into the sky. Looking back toward the car, they saw a reddish fluorescent glow with streams of light coming down from the sky to the glowing region. Grass and weeds along the roadside were standing straight up and glowing. Deep-red lines of light were seen dancing on the road. They returned to the car, and it felt hot to the touch! Soon, clouds moved in and the display was over. The authors of this article personally investigated this event within a few days of its occurrence. They found the two witnesses obviously very shaken, but believe that the accounts are fresh and unadulterated.

Such now seems to be a limited view. There is light at the bottom of the ocean! "Of particular interest is the potential for deep-sea vents and subsurface environments to support geothermally (rather than solar-) driven photosynthesis. Recent work on ambient light conditions at hydrothermal vents indicates that the photon flux generated by thermal radiation of 350 C water should be sufficient to sustain lowlevel photosynthesis, and there is at least one report of a faculative phototroph isolated from water samples taken near a deep-sea vent." A particularly important implication of this undersea light source is that the evolution of photosynthesis need not have been dependent upon the existence of life on land. Also, hydrothermal vents could have served as refuges for photosynthesizing life forms down the geological eons when: (1 ) ocean surfaces were ice-covered; (2 ) the terrestrial surface was exposed to deadly levels of radiation, as when the ozone layer was destroyed; and (3 ) when volcanism or dust from meteor impacts blackened the skies.

Tewkesbury, England. On this day, two remarkable observations were made a few seconds apart. Even so, one cannot be certain that the first caused the second. For the first observation, there were two witnesses. Both saw lightning strike a low-flying USAF jet. Mrs. E. Shobli wrote the following account: "Two forks of lightning came from the clouds in front of the plane, converged on it and gripped it. The tail end of the plane became illuminated -- vapours came from its end and formed into a bright, dense mass. I thought I was witnessing damage to the plane. The light continued to separate from the plane, downwards like a flare. It appeared as yellow, lit-up gases. These seemed to take shape, becoming brighter and denser, and then move downwards in the same direction as the plane (south). About two seconds after disappearing behind the roof there was an ear-splitting explosion. To my relief the plane reappeared unscathed." At the time of the lightning strikes, the jet was passing over a factory, where a fork-lift driver saw a dazzling blue-white ball bounce along the factory roof and enter the building.

It was a soft white light, almost strobe-like in character that pulsed irregularly. The light was bright enough to illuminate the wheelhouse deckhead and seemed to emanate from below the water, almost as if something was shining a spotlight upwards, shimmering and twirling: psychedelic projections of the 1960s were brought to mind.

From California, A. Hastings writes: "I also had an experience with 'Sparks on the Beach' as in SF#104/4 . This was on the Pacific Ocean Beach at San Gregorio, south of San Francisco, several years ago. I was walking on fairly wet sand, just above the tide line. As I stepped, the sand around my feet lit up with small bright dots of phosphorescence. I would not have said that the color was blue, but it could have been like blue-white, like the star Rigel. I found that if I stepped hard or stamped my foot, the lights flashed brighter and the lit area went out farther from my foot. I could see the movement expanding out. After a stamp or two, they did not light up as much. I assumed that this was caused by some organism that lit up when it felt pressure, and 'wore out' after it had done this a few times -- a refractory period probably occurred." (Hastings, Arthur; personal communication, March 21, 1996) Comment. This is probably a pressureinduced biological phenomenon, but we have no idea what kind of organism produces the lights.

Collectively, they record many meteor showers and fireballs; all quite respectable astronomical objects. But sometimes fuzzy, rapidly moving luminosities appear, as in the following paragraph written by J.S . Gallagher: "Diffuse luminous objects moving at angular velocities similar to those of meteors were observed during over 200 hours of meteor watching in 1991. They fell in three broad categories: arcs, patches, and 'meteors' similar in appearance to comet comas. Though I at first dismissed the possibility of their being related to meteors, I reconsidered this relation after eliminating other possible causes such as reflections from aircraft lights and tricks of vision. Their meteor-like behavior suggested that perhaps these events might be caused by clouds of exceedingly small meteoroids, visible only because of their numbers and compact grouping. Because such a formation would be unlikely to be maintained long in space, it appeared necessary that the particles involved must have maintained some weak physical contact until just prior to becoming visible. Perhaps some type of 'cosmic dust bunny,' disrupted by air resistance, might be the cause of these events." These moving patches of light also resemble the "auroral meteors" cataloged under GLA3 in Lightning, Auroras, Nocturnal Lights.

It came again, louder, just as a curtain of green light swept the entire width of the sky from north to south. Each time green flushed the sky, the bells rang, the sound softening to a gentle tinkle as the light died." (Hasselstrom, Linda; "Night of the Bells," Readers Digest , p. 185, April 1992. Cr. J.B . Dotson.) Comment. Note the correlation of the sound with the green portion of the aurora. July 29, 1990. On Coll Island in Centennial Lake, 120 kilometers west of Ottawa. Watching an auroral display, L.R . Morris heard the sound of the aurora: "It was a faint but distant windlike sound; which, by process of elimination, could not be accounted for by any phenomenon other than the aurora." (Anonymous; "Auroral Sounds," Sky & Telescope , 83:105, January 1992. Cr. D. Snowhook.) Comment. Auroras have been heard for centuries, but they "shouldn ...

And now comes a striking confirmation: 'The Great Wall.'" The Great Wall is the largest known structure in the universe at present, having superceded sundry superclusters and clusters of superclusters. The Wall is a "thin" (15 million-light-year) sheet of galaxies 500 million light years long by 200 wide; and it may extend even farther. It is emplaced some 200-300 million light years from earth. It helps outline contiguaous parts of vast "bubbles" of nearly empty space. Both the Wall and the adjacent voids are just too large for current theories to deal with. All popular theories have great difficulties in accounting for such large inhomogeneities. To illustrate an important observable -- the 2.7 K cosmic background radiation -- which is usually described as the afterglow of the Big Bang, ar gues for a very smooth, uniform distribution of galaxies. Great Walls are definitely anomalous. M.J . Geller, codiscoverer of the Great Wall with J.P . Huchra, remarked: "My view is that there is something fundamentally wrong in our approach to understanding such large-scale structure -- some key piece of the puzzle that we're missing."

Knoxville, Tennessee. "Conditions: Clear sky (no clouds, but a slight haze). Waning moon was approx. 60 above the horizon, air temperature 33 F. "I came out of the house about 6:25 AM to perform a task and, being an amateur astronomer, I looked up at the sky to see what was visible. I noticed the crescent of the waning moon appeared as a double crescent. My eyes kept trying to resolve it into a single image, but it wouldn't resolve. I then looked at several other light sources (radio tower, porch light, & street light) and determined that my vision was probably fine, as these objects appeared as single images. Looking back at the moon, it still appeared as a double image. I covered the right eye and I still saw a double image. I did the same with the left eye and got the same results. I then held out my right arm and extended my thumb to cover one crescent. I saw only one image that way. I moved my thumb and the image was again doubled. I concluded that I was viewing refracted images of the moon. "Conditions prevented continuous observation, but I was able to return approximately every five minutes. By 6:55 AM the sky was brightening and there was only a single lunar crescent. ...

... People are scouring the old literature and pouring over aerial photos for pre-1980 examples. Theories abound, especially those invoking extraterrestrials! We have room here for only a few brief items. Scorched earth in Xenia, Ohio. A hired hand of Gene Eck was harvesting a field of soybeans when he came upon a circle of flattened plants -- bent but not broken -- some 80 feet in diameter. Inside this circle was a 40-foot-diameter ring of burnt stubble. Within the ring was a patch of undisturbed foxtail 14 feet in diameter. The soybean circle was a half mile from the nearest road; no tracks led into it. (Williams, Nat; Illinois Agri-News, November 9, 1990. Cr. R.A . Ford) Column of light in Wiltshire. During the summer of 1990, teams of English ob servers scanned the cereal fields at night. At 2:30 AM, on July 25, R. Fla-herty, an experienced wildlife photographer, saw a single shaft of light descending from high in the sky toward a Wiltshire wheat field. Flaherty's view of the field itself was cut off by a ridge, so he could provide no further data. When morning came, as you probably surmised, the field displayed flattened wheat -- not the run-of-the-mill circles, but a scroll of sorts and even a triangle with rounded corners.

Science Frontiers ONLINE No. 69: May-Jun 1990 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Megawalls Across The Cosmos "The universe is crossed by at least 13 vast 'walls' of galaxies, separated by about 420 million light years, according to a team of British and American researchers. The walls seem to be spaced in a very regular way that current theories of the origin of the universe cannot explain." "Walls" of galaxies emerge when galaxy separation distance is plotted against the number of galaxies possessing specific separation distances. (128 million parsecs = 420 million light years). The astronomers have collected observations of galaxy redshifts along a linear "borehole" through the universe 7 billion light years long centered on the earth. If the redshifts are assumed to be measures of distance (as mainstream thinking demands), one gets the clumping effect seen in the accompanying illustration. (Henbest, Nigel; "Galaxies Form 'Megawalls' across Space," New Scientist, p. 37, March 19, 1990.) Comment. Not mentioned in the above article are the papers by W.G . Tifft on quantized redshifts. (See SF#50, for example.) It will be interesting to learn if "boreholes" pointed in other directions will encounter the same megawalls. If they do, the earth will be enclosed by shells of galaxies, much as some elliptical galaxies are surrounded by shells of stars. Wouldn't it be hilarious if the earth were at the center of these concentric ...

Science Frontiers ONLINE No. 120: Nov-Dec 1998 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Acoustical "vision" underwater When we (and all eyed animals) see an object, we are detecting light reflected from that object. When underwater, though, our vision is limited because light does not travel far. Sound, however, does; and sound is reflected from objects just as light is. This is of course the basis of underwater sonar, in which a sound source replaces the sun or a diver's floodlight. But even without an active sound source, the ocean is full of sound. Waves, rain, and the sounds made by marine animals create a background of noise that "illuminates" objects, not directly, but from the environment in general. Using only this enveloping background sound, it is possible to create acoustical images of objects. "Vision" of this sort is equivalent to "facial vision" in blind humans, who can hear objects using the environmental sound reflected from them. J. Potter and his colleagues at the National University of Singapore have constructed an array of underwater microphones that detects "slices" of the acoustical environment around it. When processed by a computer, images of objects emerge by virtue of the background noise reflected from them. This group has also estimated the ability of dolphins to detect and process background noise. They suggest that dolphins should be able to "see" objects at least 25 feet away without even using their active sonar; that is, ...

... particle will instantaneously determine the state of the other." (Ref. 2) This particular spooky aspect of quantum mechanics was demonstrated 15 years ago over a distance of just a few meters. Many physicists had expected (probably "hoped") that this "mysterious link" between separated particles would weaken with distance. But this quantum-mechanics effect does not conform to "common-sense" expectations! Now it seems that one particle of an "entangled pair" knows instantaneously what its mate is doing, possibly even if it is located on the other side of the universe. More quantum-mechanics spookiness is seen in "tunneling" phenomena, such as that mentioned in AR#3 , where a Mozart symphony zipped through a barrier at 4.7 times the speed of light. Physicists do acknowledge these counter-intuitive quantummechanics effects, but they are not comfortable with them. Some, on the other hand, embrace them. The late physicist H. Pagels maintained that quantum mechanics is a sort of "code" that ties together everything in the cosmos. He explained all this in his book The Cosmic Code . (Ref. 3) References Ref. 1.
