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.

Here, the sediments are riddled with methane hydrate. Why all this fuss over fizzy ice, and what is the connection between methane hydrate and pockmarks? The methane hydrate deposits represent immense accumulations of methane -- probably far more natural gas than geologists have found on the continents. Sea-bed pockmarks are thought to be formed when methane gas is explosively vented, perhaps when methane hydrate -- very unstable stuff -- suddenly decomposes. Offshore booms and mistpouffers (SF#73*) are often heard in the areas where pockmarks are common. Rich clusters of methane-dependent life forms surround methane seeps. The quantity of buried organic matter required to create all the offshore methane is staggering. Where did it all come from and how did it come to be buried at such great depths? Could some of the offshore methane be abiogenic?

The question asked in the article is whether science has missed something in its description of the origin and development of life. Just what makes molecules coalesce into cells and humans? The answer given is: spontaneous self-organization ! In other words, there is no guiding external force. Molecules do this spontaneously. There are even computer models being developed, based on a branch of mathematics called "dynamical systems," that describe how this all happens - spontaneously, of course. (Waldrop, M.

Static-universe models fit the data better than expanding-universe models. The microwave "background" makes more sense as the limiting temperature of space heated by starlight than as the remnant of a fireball. Element-abundance predictions using the Big Bang require too many adjustable parameters to make them work. The universe has too much largescale structure (interspersed "walls" and voids) to form in a time as short as 10-20 billion years. The average luminosity of quasars must decrease in just the right way so that their mean apparent brightness is the same at all redshifts, which is exceedingly unlikely. The ages of globular clusters appear older than the universe. The local streaming motions of galaxies are too high for a finite universe that is supposed to be everywhere uniform. Invisible dark matter of an unknown but non-baryonic nature must be the dominant ingredient of the entire universe. The most distant galaxies in the Hubble Deep Field show insufficient evidence of evolution, with some of them apparently having higher redshifts (z = 6-7 ) than the faintest quasars. If the open universe we see today is extrapolated back near the beginning, the ratio of the actual density of matter in the universe to the critical density must differ from unity by just one part in 1059.

Does this mean that the Big Bang, the mainstay of the astronomy we were taught in school, is now being cast aside?

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.

Preliminary study shows that those individuals who begin to explore their EEs and question conventional answers may undergo a series of similar developmental, predictable, humanizing, and transformative stages of expanding conscious awareness, which we call the Exceptional Human Experience Process (EHE Process).

... the quantization of the atom was resisted earlier in this century. They were wise because without such a reminder to be open-minded, many astronomers would automatically toss their article in the wastebasket! In fact, when Tifft's first paper on redshift quantization appeared in the Astrophysical Journal, the Editor felt constrained to add a note to the effect that the referees: "Neither could find obvious errors with the analysis nor felt that they could enthusiastically endorse publication." Even today, after much more evidence for redshift quantization has accumulated, scientific resistance to the idea is extreme. We shall now see what all this fuss is about. Tifft first became suspicious that the redshifts of galaxies might be quantized; that is, take on discrete values; when he found that galaxies in the same clusters possessed redshifts that were related to the shapes of the galaxies. The obvious inference was that the redshifts were at least partly dependent upon the galaxy itself rather than entirely upon the galaxy's speed of recession (or distance) from the earth. Then, he found more suggestions of quantization. The redshifts of pairs of galaxies differed by quantized amounts (see figure). More evidence exists for galactic quantization, but this should give the reader a feeling for the conceptual disaster waiting on the wings of astronomy. Can galaxies, like atoms and mole cules, posses quantized states? And do the findings of Tifft and Cocke undermine the redshift-distance relationship?

What cancer cells need most, if they are to grow, is sustenance, as normally provided by blood vessels. Obligingly, even though it could lead to their own demise, the tissues surrounding the cancer will grow new blood vessels to supply the killer in their midst. It has now been discovered that some particularly aggressive cancers, some melanomas, for example, can grow without the help of nearby subverted tissue. They can manufacture their own blood vessels which carry nourishment to malignant cells deep in the cancers. These self-made blood vessels differ from normal vessels in their lack of endothelial cells. They are also organized in distinctive patterns of loops around clusters of cancer cells. Normal blood vessels tend to be arranged more randomly Although they originate in specialized tissues, such as the prostate gland, the cells in aggressive cancers become unspecialized. In a sense, they revert to embryonic cells that can then become any kind of cell, such as those in blood vessels. Cancer cells are atavistic -- throwbacks to the womb.

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.

Astronomers have hitherto been content to attribute these clumped ages to collisions among the meteorites' parent bodies - the asteroids - which ply periodic orbits. However, S. Perlmutter and R.A . Muller, at Berkeley, point to the apparent 26- to 30-million-year periodicities of three terrestrial phenomena: Biological extinctions in the fossil record, Magnetic field reversals, and Terrestrial-crater ages. Could there be a connection between the clumped meteorite ages and these terrestrial phenomena? Perlmutter and Muller propose that all of these phenomena are the consequence of periodic storms of comets that invade the inner solar system from the direction of the Oort Cloud of comets that purportedly hovers at the fringe of the solar system.

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.

Normal galaxies seem to have masses of about 1011 times that of the sun. The unthinkable assumption suggests that every 108 years or so, these ordinary, unassuming galaxies become supermassive (about 1013 solar masses) for several million years. When the core of a galaxy becomes supermassive, its stars are tugged into tight new orbits. The subsequent switching off of the supermass allows the galaxy to expand outwards again. The author claims to have found just such expansion effects among the globular clusters in our own galaxy. His data are striking and quite convincing. The notorious "missing mass" problem of cosmology disappears with the cyclic supermass assumption because the time-averaged mass of each galaxy will be much higher than that observed in its normal enervated state. Doesn't this sudden temporary appearance of mass violate the laws of physics? No, says the author, physicists habitually assume a superfluid, superconducting vacuum state, which is the ultimate source of all mass-energy, when they develop their theories of fundamental particles.

Given sufficient processing, ordinary sand that is merely "noisy" when shaken can be made to "sing." Singing sand has a unique infrared signature: a broad band stretching from 3,700 to 2,800 cm-1 . This is probably due to clusters of water molecules in an amorphous silica layer on the surfaces of the sand grains. Taking a clue from the infrared spectrum, Goldsack et al shook commercially available silica gel in a bottle and heard the familiar tones of singing sand! Their conclusion is that for sand to sing the particles must be coated with naturally (or artificially) created silica gel. (Goldsack, Douglas E., et al; "Natural and Artificial 'Singing' Sands," Nature, 386:29, 1997. Also: Cohen, Philip; "Desert Dunes Sing Silica's Song," New Scientist, p. 17, March 8, 1997.) Comment. The fundamental mystery survives. Goldsack admits no insights as to exactly how muscial sands find their "voices." The subject ...
