51. In the Dark on Matter [Thunderbolts Website]
... 21, 2006 In the Dark on Matter (This TPOD first appeared on 2-28-06) Since there is no experimental or observable evidence that dark matter exists, is it just a prop for the beleaguered big bang theory? This highly speculative construct is now combined with one just as fabulous --dark energy --to shore up current cosmological dogma. In the 1930s, astronomers Fritz Zwicky and Sinclair Smith were puzzled by the motions they observed within the Virgo and Coma galactic clusters. Everything seemed to be moving too fast to be held in place by gravity. So they conjectured that something they could not see was exerting a gravitational effect on these clusters. But most astronomers were only marginally impressed. In the 1970s, however, astronomers began to examine the rotational motions of spiral galaxies such as our own Milky Way. The rotational speeds of the stars that make up spiral galaxies are far too great, they said: At such speeds the constituent stars should be flying apart. So astronomers, accustomed to thinking only in terms of gravity, calculated how much additional matter was required ...
52. The Ever-Elusive "Dark Energy" [Thunderbolts Website]
... (the shift of spectra from distant objects in space toward the red end of the light spectrum). Astronomers view redshift as a reliable indicator of the speed at which an object is moving away from the observer. The result of this interpretation is the now-famous “expanding universe”. Applying assumptions that once seemed obvious, the redshifted objects in space must mean that the universe is growing larger, as the distances between observed objects grows ever greater. Another foundational principle is that of an electrically neutral, gravity-driven universe. And if gravity is the controlling force, then it follows that distant objects ’ velocities of recession, set in motion by the big bang, are slowing down — an inescapable consequence of gravity. In fact, this too was once a foundational assumption of the big bang theory. But the astronomers ’ confidence was shattered when it was realized from the study of a particular class of supernovae, that something was dreadfully wrong. It appeared that the “expansion” of the universe was not slowing down at all. The troublemakers were the “ ...
53. Electrical Birthing of Stars [Thunderbolts Website]
... minus 240 Celsius). Traditional theory says that millions of years will pass before the cloud has collapsed sufficiently to “ignite the nuclear fusion” of a new star. Investigators had not anticipated anything comparable to the events they observed. Extremely high energies were at work, strong enough to produce X-rays — something that could never occur in an inactive and diffuse cloud in space:“ The detection of X-rays from the cold stellar precursor surprised astronomers,” states a report by SPACE.com. “The detection of X-rays this early indicates that gravity alone is not the only force shaping young stars," said Kenji Hamaguchi, a NASA-funded researcher at the Goddard Space Flight Center. The gravity-driven universe is, of course, the bedrock of popular cosmology. Now it has failed another test. “The observations reveal that matter is falling toward the core 10 times faster than gravity could account for,” the report states. According to Michael Corcoran of NASA Goddard, a co-author on the report, "The X-ray emission shows that forces appear to be accelerating matter to high ...
54. Gravity And Going Around In Ellipses [Science Frontiers Website]
... Science Frontiers ONLINE No. 35: Sep-Oct 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Gravity And Going Around In Ellipses We thought that our readers might like to know that the force of gravity apparently has no significant effect on circumnutation. Now circumnutation is the result of an "impressively ubiquitous mechanism" in all elongating plant organs. More simply, it is the elliptical weaving motion seen in the tips of growing leaves, shoots, flower stalks, branch roots, etc. In a 4- to 5-day-old sunflower seedling, the ellipse traced is 6-8 millimeters long and takes about 110 minutes. The ellipses result from differ-ential growth in the elongating plants. No one knew whether the force of gravity played a role in circumnutation until some sunflower seedlings were flown on Spacelab 1. Zero-g did not affect circumnutation at all.

55. A Tornado in Space (2) [Thunderbolts Website]
... plausible answers. What force is capable of producing high-energy jets spanning light-years? And by what means are these jets confined to a narrow stream across such distances? Jetting stars, now observed by the hundreds, find no comfortable place in the lexicon of traditional astronomy. The only known force that can prevent a stream of gas from rapidly dispersing in the vacuum of space is magnetism, and only electric currents can generate a magnetic field. But early in the twentieth century, the community of astronomers had already settled on the idea that gravity and inertia rule the heavens. Having constructed a simple and secure vision of the cosmos, they were not eager to entertain a more exotic force except as an inferior consideration, a footnote to a mathematically elegant “big picture” of the cosmos. The enigma is highlighted by the top picture above: 1500 light-years from Earth lies “Herbig Haro 111”, displaying a jet 12 light-years long with charged particles accelerated to speeds approaching 500 kilometers per second. The finely filamentary and knotted jet spans three times the distance from the ...
56. Expanding Uncertainty about the Hubble Constant [Thunderbolts Website]
... precisely opposite things. The first astronomer studied a bright eclipsing binary star system in the nearby spiral galaxy M33. He measured with state-of-the-art instruments the stars ’ orbital period and apparent brightness. He calculated the stars ’ masses, and then their absolute luminosities, and then their distance. His result was 3 million light-years instead of the 2.6 million that had been accepted. One can presume that his measurements were accurate, at least to within 6%. But the assumptions that he took for granted were entirely erroneous: He assumed that gravity was the only force holding the stars in their orbits. Without this assumption, he would have been unable to calculate their masses. But in the past century, we discovered that the Law of Gravity loses its jurisdiction outside the Solar system: stellar jets and rings don ’ t obey it, globular clusters don ’ t obey it, galactic arms don ’ t obey it, galactic jets don ’ t obey it, galaxies in clusters don ’ t obey it. (To save their belief in the Law, astronomers ...
57. A Flickering “Black Hole” [Thunderbolts Website]
... Hole” Astronomers claim that a celestial object called GRO J1655 hides a black hole. But why does its surrounding plasma flicker 450 times a second? Because the black hole is “rotating very rapidly,” astronomers say. Astronomers tell us that the “microquasar” at the center of GRO J1655 is seven times as massive as our Sun. It cannot be seen because it is a black hole formed from the collapse of an old star, now sucking in matter from surrounding space. Guided by nothing more than Einstein's view of gravity, the astronomers “know” it is there because of the energetic radiation and jets issuing from a very small region of space. To derive the mass of a black hole, mathematicians divide the apparent energy from it by the puny gravitational force, which is almost zero compared to any other force, arriving at something just this side of an “infinite concentration” of mass. The escape velocity from such an object is greater than the speed of light. Therefore, neither particles nor radiation of any kind (including light ...

... it into consideration, Thornhill showed us on film how an electric arc can create, in a piece of clay, precisely the sort of corkscrew cratering that we find on the Moon and Mars, and how electrical discharges carve 'riverbeds' like that of the Colorado at the Grand Canyon. We were also shown pictures of the Sun with various features like the sunspots which don't make sense under orthodox astrophysical laws that stipulate that the Sun is a dynamo. Whereas conventional astronomers are still searching for a way of unifying electricity, magnetism and gravity (I heard one say the other day that gravity cannot be brought together with the two others but didn't have the courage to say, 'Yes it can'!), Velikovsky suggested that gravity would be found to be an electrical effect, though he had no model to propose. Ralph Sansbury meanwhile theorised that electrons have an internal substructure and that these sub-particles move much faster than the speed of light and create the effects that we know as magnetism and gravity. Thornhill follows his lead and treats electric charge and instantaneous electrostatic ...
59. Gravity Anomaly Ripples Centered In Canada [Science Frontiers Website]
... Science Frontiers ONLINE No. 20: Mar-Apr 1982 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Gravity Anomaly Ripples Centered In Canada When scientists recently examined gravity anomaly data for North America, strange circular ripples appeared to surround a point near Hudson Bay. These ripples seem to have spread out like those from a pebble dropped into a pond, but here the ripples are actually ancient density variations in the earth's crust, now covered over by thick sediments. One hypothesis is that a 60-90 kilometer meteorite smashed into the earth some 4 billion years ago, wrinkling the young surface for several thousand kilometers in all directions around a colossal crater. Magma welling up in the crater solidified creating the nucleus of the North American continent. It is quite possible that the other continents began their existences in this way-- meteor impact. The gravity data that led to this hypothesis have been available for some time but apparently no one ever looked at them with continental patterns in mind. (Simon, C.; "Deep Crust ...
60. Stability and Dimensions of the Polar Configuration [Aeon Journal $]
... . Thus s e< (17V e /4) 1/3 m s /m e= (9100km) ms/me. Let m s /m e= 100n, where 1 <= n <= 5 (so Saturn's mass may range between that of present Saturn and that of present Saturn+ Jupiter, with allowance for ejective mass at the close of the Golden Age (2)). Then s e /n <= 910,000 km, and the acceleration at Earth due to Saturn's gravity was >= 4.8/n cm/s 2, or 0.50-0.10% of Earth's surface gravity. The effect of the stabilizing induced D'p on the axial component of force and so on the equilibrium position of planet p is treated in the Appendix. The present low magnetism of Venus indicates that in the magnetic model of the polar configuration it has a much smaller magnitude of ferromagnetic core volume Vv than Earth's V e. So its Saturnocentric distance sv is small although the ratio ms/mv would, like that of Earth, ...
