Bookshelf The Electric Universe: Slide Presentation & Notes by Wallace Thornhill (KRONIA, Beaverton, Oregon, 1997) Reviewed by Amelia Acheson Thornhill's presentation offers a visual invitation to toss aside the straightjacket of paradigm paralysis and to explore the Solar System from an electric point of view. He covers an enormous range of phenomena, from subatomic particles through stellar evolution, floodlighting our understanding of the universe with insights garnered from mythical symbols, space probes, and the plasma physics lab. As an illustration, let me compare the received explanation re the tail of Halley's Comet with Thornhill's electric account, both presented in light of photographs returned by the ESA spacecraft Giotto in March, 1986. The standard theory has it that: "Comets grow tails only when they get warm enough for ice and dust to boil off...[O]n the [sunward side], jets of gas and dust spurt from active holes in its surface and are illuminated by the sun."[1] Thornhill's electrical theory of the same data reads: "The fly-by of Comet Halley didn't show material being boiled away, instead it showed plasma beams centered on craters facing the Sun. What we saw were circular craters being formed right in front of the Giotto cameras -- producing the same kind of scarring seen on asteroids and moons. That the material was being electrically removed was confirmed by the discovery of x-rays and high energy ions near the nucleus." Thornhill goes on to discuss non-gravitational orbital anomalies, then attacks received opinion which states that a comet is defined by its size and composition. He claims instead that it is the eccentricity of the orbit of a celestial body, moving it into regions of increasing electrical stress, which creates the visible tail. "A planet on such an orbit would put on a spectacular cometary display..." (p. 48.) Thornhill found his motivation to leave the comfortable highway of orthodox astronomy and explore the lonely out-back of a new paradigm in the study of catastrophist mythology. Along the way, he incorporated insights from plasma physics and atmospheric electrical phenomena. The process of synthesizing these viewpoints into a new paradigm involved years of research, but Thornhill summarizes it admirably in a single picture, one so startling that it appears three times in this notebook. The photo in question shows an ancient statue of Zeus, thunderbolt poised in his up-raised hand. But the object called "thunderbolt" isn't the familiar zigzag lightning symbol. Instead, it's a bundle of corkscrew filaments within a football-shaped envelope, a form recognizable today as a plasmoid. The ancient artist, who presumably had no experience in plasma labs, sculpted a likeness that has been meaningless for centuries -- until a replica was produced in modern times by connecting two electrodes in a vacuum to a high-voltage source. Is this a coincidence, or were the thunderbolts of Zeus interplanetary electrical discharges? Thornhill recommends Eric J. Lerner's, The Big Bang Never Happened,[2] as an introduction to the concepts of the electrical universe. I agree, but with a couple of reservations. It should come with a warning: Lerner's political and religious opinions (including, but not limited to, barbs against catastrophism) may be offensive to some readers. In addition, while describing the scalability of plasma phenomena, jumping from events in the lab to similar events in galaxies, his imagination fails him at the stellar scale. Once inside the orbit of Pluto, Lerner drops the electric paradigm for the more conventional gravitational Solar System and nuclear powered Sun. This -- the electric Solar System -- is precisely the arena that Thornhill's notebook covers. Thus, Thornhill challenges us to drop the accepted view of the Sun as an isolated fusion factory and think of it as a focal point of galactic electrical energy. He tells us: "...although it is true that a plasma is a good conductor, it is very limited in its ability to carry current. So, if the rate of charge separation within the galaxy exceeds the capability of the plasma threading the spiral arms to carry it, the plasma will be under constant stress and current will flow continuously, powering the stars within it." (p. 28.) In defense of this outrageous claim, Thornhill points out that stellar electrical discharges provide a simple explanation for solar phenomena that have baffled the atomic energy paradigm. Among these mysteries are: Where did all the neutrinos go if the Sun is fusion-powered? Why is the corona so much hotter than the surface of the Sun? Why do the outer layers of the Sun rotate faster than the inner? Why does the solar wind accelerate as it gets farther from the Sun? And what are sunspots, anyway? Thornhill's presentation compares close-ups of sunspots to Birkeland currents -- the distinctive twisted filaments that plasmas form because of their long-range attraction and close-range repulsion. He speculates that sunspot activity, as well as the size and color of a star, are functions of the strength of the galactic plasma field the star is embedded in. In this viewpoint, even gravity becomes a variable, dependent on the electrical field in which an object is orbiting. Of course, no new theory can stand without predictions against which it can be tested, and Thornhill's predictions are no less outrageous than the rest of his theory. For example: "...there are no supermassive stars. The masses of close orbiting stars, where plasma sheaths touch, are incorrectly deduced from gravitational forces alone...I believe there are no such things as neutron stars...[and] we are left with none of the necessary precursors to the infamous black-hole...[T]hey are an unnecessary fiction required simply because astronomers consider gravity to be the only force driving the cosmos. An infinitely weak force requires an infinite concentration of mass to create the energetic events witnessed in deep space. The mathematical necessity does not make it real." (p. 32.) The questions packed into the seven pages from 25 to 32 of Thornhill's notebook titled "What is the Sun?" are enough to inspire many volumes of research. But Thornhill goes on for another 70 pages, describing how the electrical paradigm affects our understanding of the rest of the Solar System. At every scale, on every planet, satellite, asteroid and comet, he finds evidence to support an electrically driven system, one involved in recent turmoil. He compares discharges in the high-voltage lab to lightning scars on golf courses to lava tubes in Hawaii to sinuous rilles on the Moon. He finds that these enormous scars on the Moon, called rilles, have more in common with lightning scars than with collapsed lava tubes, which is the conventional astronomical explanation. On Mars, Thornhill claims that Valles Marineris, the gash across the face of the planet which the North American Indians called Scarface, is an example of a cathode discharge, like the lightning scars on a golf course. He interprets Olympus Mons, the biggest "volcano" in the Solar System, as an anode discharge, a giant "blister," comparable to fulgamites found on lightning conductors after a strike. When it comes to Venus, Thornhill displays photographs of unique arachnoid, or spider web, patterns of craters and rilles, along with on-channel cratering and parallel channels terminating in craters. All are characteristic of electrical discharges. Astronomers haven't yet agreed with catastrophists that Venus is young, but they now refer to its pristine appearance as "recently resurfaced." Thornhill's theory replaces the impact model of crater formation with an electrical discharge model for a majority of the craters in the Solar System. In defense of this viewpoint, he points out that most craters are round, whereas impact craters would more likely be elliptical. They appear in lines along the bottom of, and parallel to, sinuous rilles on many celestial bodies. Often, the craters on asteroids and the smaller moons are so large that if they were formed by impact the entire body would have been destroyed. (Mars' moon, Phobos, appears in one photograph as an illustration of this point.) When I first saw Thornhill's original slide presentation on which this notebook is based, one slide stood out for me as the most dramatic moment of the entire show. Near the end of the lecture (p. 91 in the notebook), the room was buzzing with side conversations. Without waiting for the whispers to die down, Thornhill projected his next picture. Someone gasped, and I turned to look. On the screen I saw twenty-one comets stretched out in a celestial shish kebab, one that remained coherent (the few off-line bodies actually moved continuously into straighter alignment) for a full two-earth-year-long orbit. Until I saw that slide, my view of the Saturn thesis was darkened by the skeptical thought: "Sure, catastrophism is probable. Even the electrical nature of the cosmos is beginning to make sense. But who in their right mind, no matter what the ancient sources state, could accept the concept of celestial bodies strung out in a coherent line?" But this slide wasn't a cave artist's interpretation from the dim reaches of myth. It was a photograph taken through a telescope in 1994: Comet Shoemaker-Levi 9. An observer looking toward Jupiter from any one of the outer bodies would have seen the others centered on Jupiter, their cometary tails layered into a cosmic mountain or tree. Emotionally, Thornhill's presentation was the event that, for me, changed the polar configuration from an interesting interpretation of mythology to an astronomical possibility. In addition, Thornhill has given me the richness of a new paradigm through which to view the universe. But Thornhill isn't asking for followers, only for objectivity. He thus sums up the notebook with: "...it is up to you to decide whether what I am presenting is merely science fiction -- or the beginnings of the science of the third millennium of the present era. If the latter, it is a far richer science which has no rigid disciplinary boundaries and encompasses all of human experience. That is the kind of science I would wish for my grand-children."
