In the many videos shot aboard the Space Shuttle s, we are treated to tools, even gently oscillating globules of water, floating aimlessly in midair. Even stranger are the effects of microgravity on humans and other life forms. Astronauts, for example, when they first arrive in orbit, sometimes perceive their world to be upside-down regardless of their orientation. Their nervous systems were apparently thrown for a loop when the force of gravity was cancelled out. These illusions disappear later in the mission. Speaking of loops, consider the medaka. This fish is the only vertebrate to have mated and laid eggs that developed into offspring in microgravity. Said offspring are doomed to lives of somersaulting swimming.

... The Big Bang hypothesis requires this abandonment of common sense. Both mathematicians and cosmologists instinctively hate singularities. The latter have been trying to exorcise theirs for years. Recently, S. Carneiro, a Brazilian physicist, proposed a way to get rid of this natal singularity but retain the expanding universe. First, he assumes that the universe has been around for an indefinitely (infinitely?) long time, thereby eliminating the problem of origin. Furthermore, this universe was rotating. About 11 billion years ago this spinning universe was transformed into the expanding universe we see today via that clever cosmologists' ploy called a "vacuum phase transition." Carneiro shows how the rotation of the universe-as-a -whole was converted into overall expansion in a paper submitted to the journal Classical and Quantum Gravity . But even if all of Carneiro's equations check out, angular momentum still had to be conserved somehow during the phase transition. Simple! The angular momentum of the universe-as-a -whole was transferred to the spins of all the individual planets, stars, and galaxies. In fact, the angular momentum of each astronomical entity, according to Carneiro, is proportional to its (mass)1 .7 . This turns out to be pretty close to the astonishing, still-unexplained observation that the angular momentums of planets, stars, and galaxies are proportional to their (masses)2 .

(SF#112, 114, 118, and earlier) Although some other data supported Frank's theory, many scientists scoffed. After some mildly acrimonious debate, a consensus decided that the spots on the satellite photos were merely instrument artifacts. Any lingering doubts as to Frank's house-size snowballs or "icy minicomets" impacting our atmosphere have been dispelled by a radar search by S. Knowles and his colleagues at the Naval Research Laboratory. Using the Naval Space Surveillance System's powerful radar, their scans of the upper atmosphere detected nothing resembling giant snowballs. According to Frank's estimates of the flux of incoming minicomets, the radar should have seen 800-5 ,000 of them. If Frank responds, we'll let you know.

But we don't hear much about this celestial music anymore; rather, "dances of the spheres" are in vogue. If only gravity and Newton's Laws ruled celestial motion, there would be no general solution to the hoary "three-body problem. But in the three special configurations illustrated, three bodies of equal mass can be shown to be stable. The third, the figure-of-eight, was not discovered until 1993 by C. Moore. Although mathematicians can prove it is stable, R. Montgomery admits: There is no understanding of why the orbit is stable, from either a physical or mathematical point of view. Certainly no figure-eight orbits have ever been observed in the cosmos so far, but who knows?. The situation becomes really bizarre when more than three equal masses are considered. A few of the many stable, but manifestly weird, configurations are also illustrated here. These are among the simplest. To illustrate, C. Simo has found a stable choreography for 799 bodies cavorting happily and stably together in space. And he was using only his laptop!

Discovered February 10, 1999 by an automated, asteroid-hunting telescope in New Mexico, the object's official name is 1999 CG9. Its orbit is nearly circular and 9 million kilometers farther away from the sun than the earth. Its year is 1.09 earth years. "The object's orbit is extremely unusual. Comets and asteroids that cross the earth's orbit normally have eccentric orbits. There is only one asteroid-like object, called 1991 VG, that has an similar orbit to that of earth. When it was discovered eight years ago, astronomers thought it might be a spacecraft that had escaped the earth's gravity." However, newly discovered 1999 CG9 is much too large to be a wayward piece of space hardware. The best guess is that it is a piece of the moon that was knocked off by an impacting asteroid.

In the telescope these globular clusters are spectacular objects: a million points of light in disciplined motion around a center so closely packed with stars that they cannot all be resolved. Surely such an orderly assemblage of matter should be easy to model, given the laws of celestial mechanics and high-speed computers. No so! Both theory and computer models predict that a few stars may escape a globular cluster during its lifetime of several billion years, but that most will be drawn inevitably inward as the cluster collapses. However, observation, the final arbiter, reveals that globular clusters do not follow this scenario. Indeed, some clusters seem to have collapsed already and are again evolving in a sort of "reincarnated" state that our best theories refuse to predict.

Brownlee, R. Walker, and others: ". .. suggest that interplanetary dust has probably carried organic matter to Earth since the early aeons of the solar system. The complexity of the organic molecules found on these particles has fueled the imaginations of many who ponder the role extraterrestrial matter may have played in the prebiological evolution of organic material on the primordial Earth." Beyond these conjectures, several other things about interplanetary dust particles bother scientists: "' What is surprising,' Walker notes, 'and still not understood, is the fact that the organic molecules we see in the dust particles are ...

Did earth and moon "coaccrete" at the same time? That is, did two clouds of debris simultaneously collect and coalesce into two rough spheres, which then began orbiting about a common center of gravity? Or, perhaps the earth and moon were once a single mass that ultimately fissioned due to the gravitational tugging of a passing massive object. If either of these scenarios were correct, earth and moon would have similar bulk compositions. This, however, does not seem to be the case. The abundance and distribution of iron on the moon's surface, as measured by the lunar probe Clementine , indicates that the moon is richer than the earth in refractory (high meltingpoint) compounds. The moon, therefore, almost certainly originated elsewhere, contrary to what most astronomers have longbelieved. Given the constraints of celestial mechanics, the most likely hypothesis postulates a colossal impact involving protoearth and the interloping protomoon. After considerable havoc, the two battered spheres settled down into their present configuration. Thus expire the two most popular theories of the moon's origin.

The surface of the world ocean departs wildly from a smooth sphere.

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.

Even the Neanderthals knew of it! That's hardly surprising; it's everywhere. Unfortunately, we don't know much more about it than the Neanderthals. Though it seems powerful when you trip and fall, gravity is the weakest of the fundamental four. In a helium nucleus, the force of repulsion between two protons is 1040 times the gravitational attraction between them. Weak though it may be, gravity controls the trajectory of a baseball, the motion of the planets, and the shape of our Galaxy. Physicists describe gravitation with Newton's Law of Gravitation, which incorporates the Gravitational Constant G. Here's where the embarrassment arises. Many other constants of nature, such as the charge on the electron, are known to eight significant figures. We only know G to three. What's worse, modern attempts to refine the measurement of G come up with wildly different answers. Torsion-pendulum experiments in the U.S ., Germany, and New Zealand are far apart in their G-measurements. And physicists are perplexed -- to put it mildly. Of course, G is hard to measure.

Vergano, D.; "New Evidence of Cosmic Architecture," Science News, 150:239, 1996) In a related news item, Mexican scientists have proposed that most of the matter in the universe (that elusive "dark" matter) may exist in the form of particles they dub "dilatons." Dilatons might also explain the formation of the aforesaid galactic shells. "The Mexican researchers have explored a situation in which G [the gravitational constant], instead of becoming fixed after gravity separated from the other forces [after the Big Bang], has continued to oscillate by a few per cent. They have found that the mass of dilatons required to allow G to vary in this way could account for all the Universe's dark matter." A consequence of an oscillating G would be a varying rate of expansion for the universe -- a sort of ebb and flow of the whole cosmos.

... gist of this introduction is that we have here tiny, hard-to-visualize phenomena that are so scientifically important that it is worthwhile trying to understand them. In the first abstruse phenomenon, quantum mechanical effects demonstrate that the laws of classical electromagnetism are flawed. According to the classical view, an electron cruising by an ideal solenoid (a tube with an internal magnetic field but none outside) should be unaffected; that is, the electron should not "feel" the confined magnetic field. But, in the quantum mechanical view, the "presence" of the electron is smeared out so that it penetrates the solenoid, and the electron is affected by the confined field. This has been demonstrated. A Los Alamos scientist, D. Ahluwalia, ventures that an analogous situation prevails with gravity. He notes that General Relativity predicts that a particle (or person) in free fall cannot distinguish this condition (weightlessness) from the situation in a hollow shell of matter, where the gravitational field is cancelled out. A person would feel weightless in both situations. But the strange part arises when one looks at the two situations from the perspective of quantum mechanics; that is, one puts gravity into Shroedinger's equation. Ahluwalia asserts that the particle's (or person's ) gravitational presence is smeared out, just like that of the electron outside the solenoid. In consequence, masses can "feel" their gravitational potential and will behave differently in free fall than when inside a hollow sphere, contrary to what Einstein maintained in his General Relativity.

The fluid contents of fresh eggs, however, will slosh around and prevent top action. O.K .! this is not very curious, so we'll place a hard-boiled egg in a flat pan containing a thin layer of water and give it a spin. Not only does the egg spin on end but a layer of water creeps up the side of the egg. When the water is about half way up the side of the egg it breaks up into droplets and sprays out horizontally like a rotating lawn sprinkler. No mysterious forces are involved, nor are there spooky quantum mechanics effects. The major forces operating are gravity, centrifugal force, and adhesion between the egg surface and the water. As the film of water creeps up the egg, the centrifugal force increases and overcomes the force of adhesion. Then, water droplets spray outward.

Many astronomers are equally disturbed by the recent discovery that all these fleeing stars and galaxies are not being reined in by the force of gravity. In fact, observations of distant supernovas indicate that this exodus of matter is actually speeding up. Some universal repulsive force, it seems, is operating on very large scales of distance. From an unknown somewhere energy is being added to all constituents of the cosmos. The universe is more than a cloud of debris flying away from the Big Bang's Ground Zero.

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. So much rides on this one assumption. The same situation prevails in biology, where everything is founded on the assumption that random mutations and natural selection can together generate any degree of complexity, sophistication, and innovation seen in nature.

In the inner solar system, however, some astronomers are finding "holes" where planets seem to have been ejected by unknown forces. D. Christodoulou, Louisiana State University, found one such "hole" serendipitously. He was studying how the sun and the planets might have condensed from the (hypothesized) cloud of primordial gas and dust. Factoring in gravity, rotation, and magnetic fields, he found the cloud condensing in concentric rings at just the right locations for protoMercury, proto-Venus, and proto-earth. The fourth ring, however, did not correspond to any existing planet, and the position of proto-Mars was off the mark. But the asteroids and outer planets fell rather neatly into place. The implication of these calculations is that some turmoil in the early inner solar system cast out one planet and dislocated Mars. (Hecht, Jeff; "Did Extra Planet Vanish into Outer Space?"

If these two ratios are truly equal, then G must decrease with time. Beyond the unstable feeling one gets, there is nothing in physics or cosmology to discourage a belief in time-varying gravity. Indeed, some as-tronomical data weakly support the idea. It is geophysics, though, where one finds strong evidence. Measurements of the decreasing length of the day and the expansion of the earth give about the same value for a decreasing G -- after other contributing factors have been eliminated. An interesting consequence of all this is that astrophysical theory seems to require that a decreasing G be balanced by increasing mass.

Science Frontiers ONLINE No. 62: Mar-Apr 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects More challenges to newton's law of gravitation Two experiments reported at the 1988 meeting of the American Geophysical Union in San Francisco can be added to the others that question Newton's venerable Law of Gravitation. The abstracts of these papers are short and to-the-point, so we quote them: "We have performed an experimental test of Newton's inverse-square law of gravitation. The test compared accurately measured gravity values along the 600 m WTVD tower near Raleigh, North Carolina, with upward, continued gravity estimates calculated from ground measurements. We found a significant departure from the inverse-square law, asymptotically approaching -547 36 microGal at the top of the tower. If this departure is derived from a scalar Yukawa potential, the coupling parameter is alpha = 0.023, the range is lambda = 280 m, and the Newtonian Gravitational Constant is G = (6 .52 0.01) x 1011 m3 kg-1 s-2 . We do not yet have adequate resolution to discriminate this scalar model from a scalarvector model." (Eckhardt, D.H ., et al; "Experimental Evidence for a Violation of Newton's Inverse-Square Law of Gravitation," Eos, 69:1046, 1988.) "In the late summer of 1987, an ex periment was performed to determine the value of the Newtonian gravitational constant, G, by measuring the ...

... . These lobes do not drift westward like the general field. (Ref. 2) "Core-spot pairs" of magnetic intensity seem to move westward and poleward. In the southern hemisphere, they originate under the Indian Ocean and drift under South Africa into the southern Atlantic. This motion reminds one of sunspot motion, except that sun-spots move equatorward. There may be a connection here. (Ref. 2) The general decrease in the earth's magnetic field over the past few centuries may be due to intensifying core spots, which are magnetized in a sense opposite that of the main field. (Ref. 2) Large, deep earthquakes in 1983 and 1984 produced slow, wavelike changes in the local gravitational field at the surface, as measured by new superconducting gravity meters. The periods were 13-15 hours. (Ref. 2) Gravity and magnetism measurements from satellites show strong, coincident anomalies in the Indian Ocean (3 N 81 E). In fact the whole ocean surface is depressed in this region. To explain these overlapping anomalies, geophysicists suggest that a "valley" 5-10 kilometers deep exists at the coremantle boundary.

... 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. ". .. we presume that Einstein's theory correctly describes strong gravity when we argue that certain X-ray stars are black holes, yet, at the same time, these alleged black holes are the acid test of Einstein's theory of strong gravity." (McClintock, Jeffrey; "Do Black Holes Exist?" Sky and Telescope, 75:30, 1988.) Comment. The long history of science teaches us that all theories are eventually displaced by more accurate, more all-inclusive formulations. Unfortunately, this makes textbook writing difficult.
