Its claim to fame is a very short period of rotation -- only 685 seconds. In just a shade over 11 minutes, a neutron star orbits a white dwarf, according to present thinking. The orbit diameter is only 1/7 the radius of our sun, which implies the stars themselves are also small. 4U1820-30 is the shortest-period binary ever found -- so short that astronomers are looking for other explanations. Another curious fact mentioned in this item is that X-ray binaries are much more common in globular clusters than elsewhere in the universe. What is so different about globular clusters?

Webb has called attention to a fascinating feature of the solar system. "If one calculates the total energy and the total angular momentum of the planets, the numbers turn out to be very nearly the same as those of a single planet having a mass essentially the same as the total mass of all the planets, and orbiting the sun in an orbit which is near the present-day center of mass of all the planets. The possibility that the solar system was once a binary star (or is in the process of becoming one) needs to be examined more closely."

... is "larger than our purpose." Perhaps he should have written "times", for the various portions of the universe we can see through our telescopes may be moving along different "time lines" -- on different schedules, so to speak. According to W.G . Tifft, we may have to replace our concept of one-dimensional time with three-dimensional time if we are to explain some pressing cosmological anomalies. Redshift differences of double galaxies. The horizontal axis is the redshift difference in kilometers/second. The vertical axis is the number of pairs having a given redshift difference. It all began about 1970 OTL (Our Time Line!), when Tifft showed that the redshifts of galaxies are quantized. To illustrate, the diagram indicates that the redshifts of binary galaxies tend strongly to cluster at 72 and 72/3 kilometers/ second. One would certainly not expect ponderous galaxies to orbit one another in a quantized fashion. It is almost as if binary galaxies emulate those dumbbell-shaped molecules that can spin around only at specific frequencies! Can the mechanics of the very large (galaxies) be quantized like the very small (atoms and molecules)? Tifft obviously thinks so: "Quantization, it seems, is a basic cosmological phenomenon. It must reflect some master plan." The Finnish physicist, A. Lehto, has proposed such a plan. "The new cosmology pictures the uni-verse as a set of timelines splaying outwards from a common origin in three-dimensional time. The "time" that we measure is related ...

... light years apart on the matter of parapsychology. The letter writing commenced after Anderson wrote a column in the December 1990 issue of Physics Today entitled "On the Nature of Physical Law." Here he recommended the categorical dismissal of all anomalous observations that might tear apart the fabric of science. Although Anderson did not name Jahn specifically, it was obvious to Jahn that his work was the primary target. Jahn's response was a long letter summarizing the stupendous quantity of data he and his colleagues have amassed on psi effects. "We have in hand several prodigious data bases, acquired over 12 years of continuous, intensive experimentation, that clearly establish the existence, scale and primary correlates of certain anomalous influences of human consciousness on a variety of physical systems and processes. In our Microelectronic Random Binary Generators experiment, 95 selected human operators attempted to shift the output distribution means to either higher or lower values than the chance mean, in accordance with their prerecorded intentions. In 3 850 000 experimental sequences of 200 binary samples, the overall results were that means in high intensity runs exceeded means in low intensity runs by 4.38 sigma. (The probability of chance occurrence of this outcome is less than 6 x 10-6 .) Jahn also reviewed the results of other types of psi experiments which also produced positive results. Replying to Jahn, Anderson admitted that he indeed had Jahn in mind when he wrote his original article. "What my piece actually said was within my competence as a theorist, which is to make logical connections, and the logical point I made is ...

Science Frontiers ONLINE No. 103: Jan-Feb 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Einstein's nemesis: di herculis DI Herculis is an 8th-magnitude eclipsing binary about 2,000 light years from earth. These two young blue stars are very close -- only one fifth the distance from earth to our sun. They orbit about a common center of gravity every 10.55 days. So far, no problem! The puzzle is that, as the two stars swing around one another, the axis of their orbit rotates or precesses too slowly. General relativity predicts a precession of 4.27 /century, but for DI Herculis the rate is only 1.05 /century. This does not sound like a figure large enough to get excited about, but it deeply troubles astronomers. D. Popper, an astronomer at UCLA, says: "The observations are pretty clear. I don't think there's any question there's a discrepancy and, frankly, it is an important one and it's unresolved." Accentuating the challenge to general relativity is the discovery that a second eclipsing binary, AC Camelopardalis, also violates general relativity in the same way. It seems that wherever gravitational fields are extremely strong and space-time, therefore, highly distorted, general relativity fails. Ironically, it was a very similar sort of astronomical observation that helped make general relativity a pillar of the scientific edifice early in the 20th. century. The orbit of Mercury precesses a ...

... truths of nature. To set the stage, we quote a paragraph from said article: "There is, however, a serious problem with black holes, one that leaves some scientists skeptical about their existence. The overarching mystery lies hidden at a hole's center. Einstein's general theory of relativity predicts that we will find there an object more massive than a million Earths and yet smaller than an atom -- so small, in fact, that its density approches infinity. The idea of any physical quantity becoming infinite flies in the face of everything we know about how nature behaves. So there is good reason to be skeptical that such a nasty thing could happen anywhere at all." Among the observations that hint at the reality of black holes are the X-ray binaries. In a typical X-ray binary, prodigious, flickering fluxes of X-rays reveal the presence of an ultradense star and an orbiting companion. The rapid orbital motion of the companion star tells us that the central X-ray star has a mass of more than three suns. General Relativity assures us that such a star can only collapse further to form a black hole. Therefore, black holes must exist. J. McClintock, the author of this article, does not buy this reasoning. General Relativity, he says, has been shown to be valid so far only in weak gravitational fields, not in the very powerful gravitational fields of an X-ray star.

A nearby binary star, Geminga, has a period of this length. It seems that the 160-minute oscillation of the sun is far too long to be a solar pressure wave, and external forces could conceivably be involved. This article also mentions "the throbbing earth" reported in SF#30, an effect which may result from gravitational waves emanating from the center of our galaxy.

The observational technique used resembles that employed in the discovery of the now-famous rings of Uranus. Briefly, the star being observed blinks out not once in a clean-cut fashion but in a complex scenario that may indicate the presence of a second body. To illustrate, during the 1975 occultation of a star by the asteroid Eros "all sorts of people saw things," meaning secondary events or extra dimmings. Another kind of supporting evidence comes from the light curve of 44 Nysa, which closely resembles that of an eclipsing binary star. (Anonymous; "Asteroids with Moons?" Science News, 114:36, 1978.)

... of Scientific and Technical Terms ) An Abstract. Stellar aberration, discovered nearly three centuries ago by Bradley, was immediately recognized as a phenomenon owing to the velocity of the earth in its orbit around the sun. Einstein provided an explanation of aberration in his famous 1905 paper using his new relativity theory, and his explanation remains essentially without modification in many modern textbooks. Herein, we show that his explanation is very much in disagreement with measurement. (Hayden, Howard C.; paper to be published in Galilean Electrodynamics , vol. 4, no. 5, 1993.) A Comment. The essence of Prof. Hayden's main argument is that, if stellar aberration depended on the relative velocity between source and observer (as Einstein maintained), then each component of a spectroscopic binary star would have drastically different stellar aberration, contrary to observation.

... 3/4 -inch polystyrene spheres cascaded down through an array of 330 nylon pegs into 19 bins. According to chance a Gaussian distribution of spheres should be found in the bins. The operators were asked to mentally try and skew the distribution to the right or left, or construct a baseline, as with the REG. Once again, there was statistically significant evidence of a mental influence. Jahn's group also engaged in remoteviewing experiments, in which subjective factors were suppressed as far as possible. An excerpt from the report's Abstract summarizes this phase of the work nicely: "Quantitative analysis of a large data base of remote perception experiments reveals similar departures from chance expectation of the degree of target information acquired by anomalous means. Digital scoring techniques based on a spectrum of 30 binary descriptors, applied to all targets and perceptions in the experimental pool, consistently indicate acquisition of substantial topical and impressionistic information about remote geographical locations inaccessible by known sensory channels." In some trials, the percipient was asked to describe the remote scene even before the location was selected or visited!

In other words, isolated digits of pi can be quickly calculated should an urgent need arise. P.B . Borwein et al, at Simon Fraser University, announced this "curious" discovery in October 1995. This is the equation mathematicians use in calculating isolated digits of pi. Innuendo aside, there is something more than "curious" here. It seems that the formula works only for hexadecimal (base-16) digits of pi. These can be easily converted into binary (base-2 ) digits. Strangely, it does not work at all for our familiar decimal (base-10) digits of pi. Not to worry though! Y. Kanada and colleagues, at the University of Tokyo, have now computed pi to 4,294,960,000 decimal digits. But, they have found a puzzling asymmetry. In the first 4 billion digits, the decimal digit 6 occurs 400,033,035 times, but 2 shows up only 399,965,405 times! Shouldn't all ten digits appear with the same frequency?
