England. We quote from a London cable to the New York Times. "Several nights through the week were marked by strange atmospheric effects which Dr. Norman Lockyer of the South Kensington Solar Physics Laboratory believes to be a display of the aurora borealis, though personally I have not observed any colored streamers. "Following sunsets of exceptional beauty and twilight effects remarkable even in England, the northern sky at midnight became light blue, as if the dawn were breaking, and the clouds were touched with pink, in so marked a fashion that police headquarters was rung up by several people, who believed a big fire was raging in the north of London." (Anonymous; "Like Dawn at Midnight," New York Times, July 5, 1908. Cr. M. Piechota) Comment. Actually, all of northern Europe saw a succession of very bright nights beginning June 30, 1908. It was even possible to take photographs at midnight. The cause was not the aurora borealis but rather the Tunguska Event (Siberian Meteor) of June 30, 1908. Of course, Western Europe did not know what had happened in Siberia for years. Terrestrial dust from the Tunguska Event that was blasted into the upper atmosphere or perhaps particulate matter accompanying the impacting object (probably a comet) was apparently the cause of the nightime airglow.

Does this mean that the Big Bang, the mainstay of the astronomy we were taught in school, is now being cast aside? After all, the Big Bang does model fairly well three important observations: The apparent expansion of the universe; The 3 K microwave background; and The abundances of the light nuclei. But try as they may, cosmologists have not been able to coax the Big Bang model to explain the large-scale lumpiness and structure of the galaxies and galaxy clusters. One problem with the Big Bang is that it has too many free parameters -- too much theoretical slack. Many cosmologists are now looking for a better model. This better model, to use the words of P. Coles, should be more "exciting" and "stranger," something "perhaps not even based on General Relativity." (Coles, Peter; "The End of the Old Model Universe," Nature, 393:741, 1998.) Questions.

Science Frontiers ONLINE No. 109: Jan-Feb 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Too Much Order In The Early Cosmos Astronomers are becoming accustomed to the idea that many nearby galaxies are concentrated in spherical shells separated from one another by about 400 million light years. This onion-skin geometry is inferred from the fact that galactic red shifts cluster around specific values; that is, they are quantized. Since red shifts are held to be proportional to distance in the expanding universe paradigm: Voila! We have shells! This evidence of nearby cosmic order does not seriously disturb cosmologists, because in the nearby galaxies we are seeing that portion of the universe that is billions of years old. In other words, nearby there has been enough time for some degree of order to have evolved out of the primordial chaos of the Big Bang. Now though, "deep" surveys of galaxies, looking much farther back in time, still show clustered red shifts -- not the expected increasing chaos required by theory. Although the surveys are incomplete, astronomers are discomfited by this early lumpiness. Their theories say that there was not enough time for galaxies to organize themselves into sheets, shells, and skeins. If further "deep" probings of the cosmos confirm this redshift clustering, we may need a new evolutionary scenario. Good bye Big Bang and expanding universe!

In some 200 hours of observation along the Norwegian coast, there were nine clear-cut cases where auroral arcs lined up northsouth directly above the coastline. These alignments lasted 5-10 minutes. L. Frank (of icy-comet notoriety) confirmed this effect with observations from NASA's Polar satellite. Sometimes auroral arcs aligned themselves parallel to the Greenland coast for hundreds of kilometers. Auroral arcs that fanned out east-to-west seemed to hit a barrier when they reached the Greenland coastline; they seemed to be deflected by it, even though the coast was more than 100 kilometers beneath them.

Once we learn how to measure neutrinos really well, we can start looking for intelligent signals impressed upon them by advanced extraterrestrial civilizations. W. Simmons and colleagues at the University of Hawaii at Manoa point out that neutrinos are much better than electromagnetic waves for galaxy-wide communication. They are not blocked by dust nor are they smeared out by ionized gas. Any civilization clever enough to colonize the entire galaxy would want to send out neutrino signals if only to keep clocks in far-flung star systems synchronized. Simmons et al calculate that a neutrino detector containing a cubic kilometer of seawater could probably detect neutrino signals from artificial sources located within 3,000 light years of earth. A detector that might be able to do this is being installed in the ocean off the Hawaiian Islands. Naturally, it has an acronym: DUMAND = Deep Underwater Muon and Neutrino Detector.

Sustained winds blowing over the large areas of ice generated enough horizontal force to propel the ice sheets with their cargos of rocks.

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

... 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 it exists there. In other words, our philosophical expectation of symmetry in the universe-as-a -whole is incorrect. The universe on the average is evenly split between left- and right-handed molecules, but there are "islands" or "pockets" which are left- or right-handed. Earth life is one of these "islands." Given the chance, amino acids and other organic molecules would exist evenly split, but physical phenomena, such as circularly polarized light, tip the scales -- to the left, in the case of terrestrial life. But that would mean that some physical phenomena are not symmetrical!

Indeed, a commentary in Nature by C.A . Murray begins as follows: "Larsen and Grier, on page 230 of this issue [Ref. 2], show that two similarly charged polymer spheres suspended in water can attract each other when they are several diameters apart. This surprising result casts some light on a tricky theoretical many-body problem that has been swept under the rug for a century, and it has implications for colloids in nature and in industrial processes." (Ref. 1) Exactly what happens is not yet clear. This counter-intuitive phenomenon occurs in a many-body situation, where screening charges are established between the like-charged spheres. Although Coulomb's Law states that like charges repel one another, the presence of screening particles complicates the picture, as do the van der Waals dipole interactions. The microscopic situation may be murky, but there is no doubt on the macroscopic level that unexpected attractive forces are operating. For example, when sub-microscopic, electrically charged latex spheres are suspended in water, one would expect a homogeneous colloidal soup. Instead, the tiny, charged spheres pull themselves together in patchy, but ordered arrays. These metastable groupings of spheres are called "crystallites." Theorists are not certain what is going on.

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.

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.

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 ...

We formally classify this item under GEOPHYSICS because scientists are still pondering how these glows are created.

Abstract. The big bang theory postulates that the entire universe originated in a cosmic explosion about 15 billion years ago. Such an idea had no serious constituency until Edwin Hubble discovered the redshift of galaxy light in the 1920s, which seemed to imply an expanding universe. However, our ability to test cosmological theories has vastly improved with modern telescopes covering all wavelengths, some of them in orbit. Despite widespread acceptance of the big bang theory as a working model for interpreting new findings, not a single important prediction of the theory has yet been confirmed, and substantial evidence has accumulated against it. Here, we examine the evidence for the most fundamental postulate of the big bang, the expansion of the universe. We conclude that the evidence does not support the theory, and that it is time to stop patching up the theory to keep it viable, and to consider fundamentally new working models for the origin and nature of the universe in better agreement with the observations." This paper's author, T. Van Flandern, dismisses quickly two pillars of the Big Bang; i.e ., its supposed predictions of the cosmic microwave background and the abundances of light elements in the universe: "The big bang made no quantitative prediction that the "background" radiation would have a temperature of 3 degrees Kelvin (in fact its initial prediction was 30 degrees Kelvin); whereas Eddington ...

Does theory require black holes? In 1939, R. Oppenheimer and H. Snyder showed on paper that a massive star could collapse and create a black hole, assuming the correctness of stellar theories and General Relativity. Initially, scientists were skeptical about black holes because of their bizarre properties: They emit no light and inhale unwary starships. Black holes are also singularities, and singularities make scientists nervous. In the black-hole singularity, thousands of stars are swallowed and compressed into an infinitesimally small volume. (Ref. 1) This grates against common sense. The philosophical uneasiness about black holes is worsened by the discovery that they: ". .. threaten the universe with an irreversible loss of information, which seems to contradict other laws of physics." (Ref. 2) Adding to these problems are nagging doubts about General Relativity, which underpins black-hole theory. Recently, some theorists have shown that General Relativity requires that two bodies of approximately equal size not attract one another!

An astronaut standing on the moon watching the spot where the sun is about to rise would see first of all two well-recognized phenomena: the solar corona (even though the solar disc is still well below the horizon) and the zodiacal light (sunlight reflected from interplanetary dust). In addition, the astronaut would detect a glow along the horizon itself, as in the illustration. Since the moon is virtually airless, there should be none of those gas molecules and suspended dust particles that cause the sunsets and sunrises that we admire so much here on earth. Still, there must be something suspended above the moon's surface to scatter light from the sun still located just below the horizon.

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.

Fraser noticed that some trees in the dark woods glowed spectacularly in the car's headlights -- almost as if they were covered with snow. Obviously snow was out of the question. Instead, the glow was some form of reflection from dew-covered leaves, and only from certain species of trees at that. "Later nocturnal expeditions with a powerful flashlight (a proceeding that aroused dark suspicions in at least one local gamekeeper) showed that it favoured only certain types of conifer and a few shrubs such as the yew and rhododendron. The explanation lies in the contact angle of the droplets on the leaves: as this rises above 90 degrees or so, the proportion of light from the car's headlamps that is reflected back towards the occupant increases, and for angles above 140 degrees, the retroreflection becomes spectacular.

Why don't they enlarge in radius and dissipate?

We have already reported on the mysterious light flashes (SF90) and radio emissions (SF#94). Now, we record similar, possibly intimately related flashes of energy in a different portion of the electromagnetic spectrum. "Detectors aboard the Compton Gamma Ray Observatory have observed an unexplained terrestrial phenomenon: brief, intense flashes of gamma rays. These flashes must originate in the atmosphere at altitudes above at least 30 kilometers in order to escape atmospheric absorption and reach the detectors." The energies of the gamma rays in the flashes are very high. They are typical of the braking radiation (Bremsstrahlung) from 1,000,000 electron-volt electrons. Since most of the gamma flashes originate over regions where thunderstorms are frequent, it is tempting to associate them with lightning. Ordinary lightning, however, is not energetic enough to generate the gamma flashes and, of course, it does not occur above 30 kilometers altitude anyway. G.J . Fishman et al, who reported on this new phenomenon in Science, speculate that some hitherto unrecognized, high altitude electrical discharges occur high above areas hosting thunderstorms. Possibly, upwardly directed lightning (" rocket lightning") is involved in all three of the newly found flashes in the radio, optical, and gamma portions of the electromagnetic spectrum. (Fishman ...

... "Contemporary neuroscience suggests the existence of fundamental algorithms by which all sensory transduction is translated into an intrinsic, brain-specific code. Direct stimulation of these codes within the human temporal or limbic cortices by applied electromagnetic patterns may require energy levels which are within the range of both geomagnetic activity and contemporary communication networks. A process which is coupled to the narrow band of brain temperature could allow all normal human brains to be affected by a subharmonic whose frequency range at about 10 Hz would only vary by 0.1 Hz." (Ref. 1) Second, Jahn sees a remarkably similar information channel, but of a cryptic nature, connecting humans to the environment in PEAR's psychokinesis and remoteviewing experiments. In describing his model of this information channel, Jahn writes: "Like physical light (energy) and elementary particles (mass), consciousness (information) enjoys a wave/ particle duality that allows it to circumvent and penetrate barriers and to resonate with other consciousnesses and with appropriate aspects of the environment. Thereby it can both acquire and insert information, both objective and subjective, from and to its resonant partners." (Ref. 2) The immense body of empirical data amassed by Jahn's PEAR laboratory certainly suggests the existence of an allpervading information-transfer medium that is independent of space and time. Persinger relies upon a different corpus of research: neurological experiments as well as scores of his own studies of the effects of the geomagnetic environment upon human perception and consciousness. Both Jahn and Persinger write of information flow. The ideas of brain matrices and resonances ...

... Sourcebook Project Sourcebook Subjects "BLUE JETS" EMITTED UPWARD FROM TOPS OF THUNDERCLOUDS Geophysicists have recently recognized that something very strange transpires above thunderclouds. First, there is the phenomenon we have called "rocket lightning" in our books and newsletters. Scientists now call these upwardly directed discharges "sprites." (SF#84) The sprites are short-duration red flashes in the ionosphere, sometimes with bluish tendrils extending down into the thunderclouds. Second, there are the newly recognized "blue jets," a new class of upward discharges. This phenomenon is detailed in a paper by E.M . Wescott et al. Here is their abstract: "Initial observations of as newly documented type of optical emission above thunderstorms are reported. "Blue jets," or narrowly collimated beams of blue light that appear to propagate upwards from the tops of thunderstorms, were recorded on B/W and color video cameras for the first time during the Sprites94 aircraft campaign, June-July 1994. The jets appear to propagate upward at speeds of about 100 km/s and reach terminal altitudes of 40-50 km. Fifty-six examples were recorded during a 22-minute interval during a storm over Arkansas. We examine some possible mechanisms. but have no satisfactory theory of this phenomenon." (Wescott, E.M ., et al; "Preliminary Results from the Sprites94 Aircraft Campaign: 2. Blue Jets," Geophysical Research Letters, 22:1209, 1995.) Comment. The blue jets may be related to other controversial phenomena that suggest surface-to- ...

... the presence of a "global control element" that turns the pigment-secreting cells on and off in the correct order -- something like a computer-controlled loom! "Given this generating mechanism, some shell patterns are easy to understand. A series of vertical stripes -- that is, stripes running perpendicular to the growing edge -- implies a static distribution of pigment secreting cells in the mantle margin. Where a cell or group of cells is permanently turned on, there is a dark stripe of pigment, and where the cells are dormant, there is an unpigmented space. The complementary pattern -- horizontal stripes, parallel to the growing edge -- results from a temporal rather than a spatial oscillation. All the secretory cells turn off and on in synchrony, so that light and dark bands are left behind on the surface of the shell as the growing edge moves on." All well and good, but some seashells have intricate patterns that require modellers to imagine traveling waves of excitation, oscillating chemical systems, signals that travel faster than chemical diffusion, and longrange synchrony employing a "global control element." These patterngenerating schemes are clever and rather successful on the theoretical level. Indeed, the seashell modellers are rather smug about their accomplishments. (Hayes, Brian; "SpaceTime on a Seashell," American Scientist, 83:214, 1995.) Comment. The seashell modellers, of course, do not have to explain how or why "global control elements" evolved. The biological rendering of "long-range synchrony" is left unexplained. ...

... 1725, returning to milky-white patches before eventually disappearing at 1730." (Watson, M.M .; "Bioluminescence," Marine Observer, 65:59, 1995.) Bioluminescent displays often possess mixed geometries. In this illustration, both moving bars and rotating spoked wheels are noted. Location: East Indian Archipelago. Time: 1959. May 23, 1994. Equatorial Atlantic. Aboard the m.v . Taunton enroute to Richards Bay. "At 0550 UTC the vessel was passing through an area of thunderstorms with moderate to heavy rain and the nearest area of lightning was about 4 n. mile away when the Chief Officer went onto the bridge to observe some bioluminescence. At this point he noted that the hairs of his arms and moustache were glowing with a bluish light although no tingling or any other sensation was felt. A check of the vessel's aerials revealed no traces of 'St Elmo's fire' and the observer seemed to be the only object affected. The glow disappeared once he retreated to the wheelhouse but reformed when he went outside again but without the same intensity." "What was noticeable was that the bioluminescence was only seen at the same times as the St. Elmo's fire, and the observer was left wondering whether it appeared in response to a heavy static charge in the air." (Nicholls, G.; "Bioluminescence," Marine Observer , 65:69. 1995.) Comments. We see in the first account remarkable changes in patterns and colors, all in the same display. ...
