Bubble Magnets
Nov 05, 2009

Astronomers say that exploding bubbles of magnetic energy might have helped form galaxy clusters.


A little over fifty years ago, before space shuttles, before the Hubble Space Telescope, and before satellite technology, electricity in space was not considered. Because the first teams of space scientists were "steely eyed missile men" with backgrounds in aeronautics and chemical fuel reactions, when evidence for electric current flow around Earth was found it was called a "radiation belt."


Although Kristian Birkeland had conducted experiments almost fifty years before the first science package was launched into Earth orbit, electricity remained unfamiliar to researchers conditioned to think in terms of gravity and mass. They had no concept of charged particles generating filamentary structures that could interact and create energetic phenomena—Birkeland's terella research and his study of Earth's aurorae were forgotten.


That lack of familiarity continues today when moving charged particles from the Sun are called a “wind” instead of an electric current. Charged particles impinging on a planet or a moon are referred to as a “rain” instead of an electrical discharge. Ionized particles moving within a helical magnetic field are called "jets of hot gas" instead of field-aligned flows of electricity. When abrupt changes in the density and speed of charged particles are observed, those changes are called a “shock wave” instead of a double layer. Birkeland continues to fret from beyond the pale.


Magnetic fields in space can be detected more easily than electric currents, so modern astronomers think that the fields are fragments left over from the Big Bang. They write a blank check based on that conclusion to explain how the primordial structures that make up the universe were formed. An analysis of data from the Chandra X-ray Observatory seems to indicate that "bubbles" over 60,000 light years in diameter are slowly percolating out of galaxy clusters. Within this cosmic fizz are supposed to be intense magnetic fields that are released when the bubbles burst. Research teams speculate that the fields detected in remote galaxy clusters are caused by the bursting bubbles.


Galaxy clusters are thought to be made of individual galaxies embedded in hot gases and dark matter, so astronomers were surprised to find the bubbles, or cavities, within the overall x-ray emissions detected by Chandra. Inside most of the cavities are bright radio sources that could be caused by the explosion of highly energetic particles, but the cause of the explosions and the source of the particles is not known.


Even so, according to Brian McNamara from Ohio University: "We've known for the past 15 to 20 years that magnetic fields exist [in galaxy clusters], but we didn't understand how they got there. This could be a viable mechanism."


The fact that moving charges constitute an electric current and that those currents generate magnetic fields has been known since the days of Michael Faraday. However, since "perception is reality," as the saying goes, a lack of knowledge means a lack of vision. As previously stated, charged particles in motion constitute an electric current and that current is wrapped in a magnetic field. As more charged particles accelerate in the same direction the magnetic field gets stronger. That is a familiar idea to electrical engineers, but when astronomers find magnetism in space they are mystified. They resort to ironic ideas about galaxy-wide voids with magnetic fields frozen inside them.


Another fact that is not considered when attempts are made to explain structure in the universe (or smaller-scale planetary examples) is that for charged particles to move, they must move in a circuit. Hannes Alfvén, the father of plasma cosmology, identified several interacting circuits in the Earth's magnetosphere. One of those circuits forms the polar aurorae due to electric current effects linking the Sun with our planet's charged environment.


On the largest scale of all, the universe, larger energetic events are not explained by reference to local conditions. The effects of an entire circuit—which may encompass clusters of galaxies—must be considered. For this reason, while the consensus scientific worldview only permits isolated galactic "islands" in space, the Electric Universe hypothesis emphasizes connectivity with a vast network of electrically active "transmission lines." That spatial wiring is composed of Birkeland currents.


Loops and filaments suddenly expand and explode, throwing off massive bubbles of plasma that can accelerate to near light-speed. Jets from opposite poles of a galaxy end in energetic clouds emitting copious radio and x-ray frequencies. These are facts based in plasma science and not the traditional theories of gas kinetics, gravity, or particle physics. Astrophysicists see magnetic fields, but they do not perceive the underlying electricity, so they are at a loss to explain them.

Plasma behaves in unfamiliar ways. Its similarities to hot gas are overshadowed by its differences. It is habitual perception that makes it difficult to see plasma as something different. By breaking free from a priori assumptions, the unfamiliar behavior of plasma will become familiar and astronomers will perceive a new universe.

SPECIAL NOTE - **New Volumes Available:
We are pleased to announce a new e-book series THE UNIVERSE ELECTRIC. Available now, the first volume of this series, titled Big Bang, summarizes the failure of modern cosmology and offers a new electrical perspective on the cosmos. At over 200 pages, and designed for broadest public appeal, it combines spectacular full-color graphics with lean and readily understandable text.

**Then second and third volumes in the series are now available, respectively titled Sun and Comet, they offer the reader easy to understand explanations of how and why these bodies exist within an Electric Universe.

High school and college students--and teachers in numerous fields--will love these books. So will a large audience of general readers.

Visitors to the site have often wondered whether they could fully appreciate the Electric Universe without further formal education. The answer is given by these exquisitely designed books. Readers from virtually all backgrounds and education levels will find them easy to comprehend, from start to finish.

For the Thunderbolts Project, this series is a milestone. Please see for yourself by checking out the new Thunderbolts Project website, our leading edge in reaching new markets globally.

  Thunderbolts of the Gods

  Follow the stunning success of the Electric Universe in predicting the 'surprises' of the space age.  
  Our multimedia page explores many diverse topics, including a few not covered by the Thunderbolts Project.  

Authors David Talbott and Wallace Thornhill introduce the reader to an age of planetary instability and earthshaking electrical events in ancient times. If their hypothesis is correct, it could not fail to alter many paths of scientific investigation.

Professor of engineering Donald Scott systematically unravels the myths of the "Big Bang" cosmology, and he does so without resorting to black holes, dark matter, dark energy, neutron stars, magnetic "reconnection", or any other fictions needed to prop up a failed theory.

In language designed for scientists and non-scientists alike, authors Wallace Thornhill and David Talbott show that even the greatest surprises of the space age are predictable patterns in an electric universe.
