# Electrically Driven Stars and Galaxies: Wallace Thornhill's Birkeland Currents in the Electric Universe

In the vast theater of the cosmos, what if the light of stars and the majestic spiral arms of galaxies are not primarily the result of internal nuclear fires and gravitational collapse alone? What if they are instead illuminated and organized by invisible rivers of electric current flowing through the plasma that fills interstellar and intergalactic space?

This is the compelling vision explored by the late Wallace Thornhill (1942–2023), an Australian physicist and one of the principal voices of the Electric Universe (EU) theory, developed in close collaboration with David Talbott through the Thunderbolts Project. Far from fringe speculation, their work builds on the established foundations of plasma physics and the pioneering insights of scientists like Kristian Birkeland and Nobel laureate Hannes Alfvén. It invites us to look at familiar astronomical phenomena through a different lens—one where electromagnetism, the strongest long-range force in the universe, plays the dominant role in cosmic structure and energy.

Let us explore these ideas openly, as Thornhill encouraged: with curiosity, attention to laboratory plasma experiments that scale across 14 orders of magnitude to cosmic sizes, and a willingness to question long-held assumptions.

## The Plasma Cosmos and the Discovery of Birkeland Currents

Over 99.9% of the visible matter in the universe exists in the plasma state—the fourth state of matter, consisting of ionized gas where electrons and ions move freely. Unlike neutral gas, plasma is an excellent conductor of electricity and responds dramatically to electromagnetic fields. It can self-organize into filaments, double layers, and complex structures under the influence of electric currents and the magnetic fields those currents generate.

Kristian Birkeland, the Norwegian physicist working in the early 20th century, proposed that Earth's auroras were powered by electric currents flowing from the Sun. His laboratory "terrella" experiments (small magnetized spheres in vacuum chambers) replicated auroral-like displays. For decades, this was dismissed, but satellite measurements in the 1970s and later missions like NASA's THEMIS confirmed the existence of "magnetic ropes"—twisted bundles of electric current connecting the Sun and Earth. These are now called **Birkeland currents**.

*Paired plasma filaments twist into ropes under their own magnetic fields. Parallel currents attract, forming the helical structures observed from Earth's auroras to cosmic scales.*

Birkeland currents are field-aligned plasma filaments. Because a current generates a magnetic field that encircles it (Ampère's law), parallel currents attract each other, causing the filaments to twist into rope-like or helical structures—often appearing as pairs or bundles. These currents can transport enormous amounts of energy over vast distances with remarkable efficiency. In space, where densities are low, they can persist in a "dark mode"—carrying current and delivering power without emitting visible light until conditions (higher density or current) cause them to glow.

Hannes Alfvén, whose work on magnetohydrodynamics earned a Nobel Prize, championed plasma cosmology. He demonstrated that many cosmic phenomena could be replicated in laboratory plasma experiments and scaled up. Alfvén warned that ignoring electric currents in space would lead models astray. Thornhill and Talbott extended this into a broader synthesis they called the Electric Universe.

## Stars as Foci in Galactic Electrical Circuits

In the standard astrophysical model, stars are self-gravitating spheres of plasma powered by thermonuclear fusion in their cores. Gravity provides the pressure to sustain fusion; the energy diffuses outward over millions of years. This model has explained much, yet it has also required adjustments for observations like the coronal heating problem (the Sun's outer atmosphere is millions of degrees hotter than its surface), the acceleration of the solar wind, and historical neutrino flux discrepancies.

Thornhill's perspective, building on earlier ideas from Ralph Juergens, offers a different picture: **stars are not isolated power plants but loads or focal points in much larger galactic electrical circuits.**

### Birth of a Star

Stars form within molecular clouds along networks of Birkeland current filaments. As predicted by Alfvén and observed spectacularly by the Herschel Space Observatory, these filaments often appear as long, relatively uniform "strings of pearls" or threads where young stars are strung like beads. The mechanism is the **Z-pinch**: the azimuthal magnetic field generated by the axial current compresses the plasma radially inward. Matter is drawn toward the filament axis through processes like Marklund convection, concentrating material until densities and temperatures allow a star to ignite.

*Young stars align along a plasma filament in a molecular cloud, like beads on a string. The Z-pinch effect of Birkeland currents concentrates matter, as predicted by plasma cosmology and observed by Herschel.*

Once formed, the star does not sever its connection to the current. The galactic Birkeland current continues to thread through or around it, delivering energy. The filament feeding the star may remain in dark mode— invisible to our telescopes—yet still supplies the power that sustains the star's luminosity and activity. In this view, stars are more like streetlights along a cosmic power line than self-contained furnaces.

### The Electric Sun

For our own Sun, Thornhill and colleagues describe an "Electric Sun" model. The Sun sits within a larger galactic circuit. Electric currents flow into the heliosphere, creating a complex plasma environment with double layers and sheaths. The visible photosphere is interpreted as the luminous surface of a plasma discharge or double layer, not the top of a convective zone overlying a fusion core. The corona, with its million-degree temperatures and dynamic structures (loops, prominences, flares), is powered directly by electrical activity and particle acceleration in the surrounding plasma—explaining the "coronal heating paradox" naturally.

Sunspots, flares, and the solar cycle itself become understandable as oscillations and instabilities in the electrical circuit rather than purely magnetic or convective phenomena. The model predicts behaviors consistent with observations of charged particle flows, synchrotron radiation in certain contexts, and interactions at the heliopause (such as those mapped by IBEX and Voyager, which showed no traditional bow shock but features more aligned with electrical boundaries).

Critically, this does not necessarily eliminate fusion entirely in all layers or contexts, but repositions it: the primary energy input sustaining the star's output comes from the external galactic current. The star is a focus where energy is concentrated and radiated.

This framework elegantly accounts for why stars often appear aligned along filaments, why young stellar clusters show rapid variability (changing electrical loads), and why stellar properties can be more uniform across different masses than pure fusion models might suggest in isolation.

*In the Electric Sun model, our star is sustained by incoming currents from the larger galactic circuit rather than solely by internal fusion. Double layers and sheaths in the surrounding plasma power the corona and activity.*

## Galaxies: Organized by Intergalactic Currents

If stars are lit by galactic currents, galaxies themselves are nodes or organizing centers within even larger intergalactic Birkeland current networks.

*Spiral arms, magnetic fields, and jets trace electric currents on galactic scales. Galaxies form and light up at pinches and nodes within the vast network of intergalactic Birkeland currents.*

Spiral galaxy arms frequently align with regions of enhanced radio emission and magnetic fields—signatures consistent with current-carrying filaments. The rotation curves of galaxies (flat velocities at large radii) have long been attributed to invisible dark matter halos. In the EU view, electromagnetic forces and the tension or dynamics within plasma filaments and pinches can contribute significantly to the observed dynamics, potentially reducing reliance on unseen mass.

Active galactic nuclei, relativistic jets, and radio lobes—dramatic outflows from galaxy centers—are reinterpreted as powerful electrical discharges and plasma pinches rather than (or in addition to) purely gravitational accretion onto supermassive black holes. The energy source is the larger cosmic circuit.

On the largest scales, the "cosmic web" of filaments connecting galaxy clusters, revealed by redshift surveys and simulations, matches the expected morphology of a vast network of Birkeland currents. Galaxies form and light up at the intersections or pinches within this web.

Thornhill emphasized the scalability: laboratory plasma phenomena—Z-pinches, double layers, filamentation, critical ionization velocity—repeat across vastly different scales. What we see in a plasma focus device or aurora can inform what happens in a planetary nebula, a star, or a galaxy.

## Successful Predictions and the Appeal of Simplicity

One strength Thornhill highlighted is the theory's predictive track record in certain areas:

- Filamentary star formation and "strings of pearls" structures, confirmed by Herschel.
- Specific features of the heliosphere and its interaction with the interstellar medium (IBEX ribbon/hotspots interpretable as filament interactions; absence of a strong mechanical bow shock).
- Electrical explanations for planetary nebulae morphologies, supernova remnant features, and cometary phenomena.

The model strives for conceptual economy: fewer invisible entities (dark matter, dark energy, primordial singularities in some interpretations) and greater reliance on known physics tested in laboratories. It returns cosmology to a more empirical, engineering-like approach—"how does nature actually do this?"—rather than purely mathematical constructs.

Of course, the Electric Universe remains outside the mainstream consensus. It faces challenges in quantitative detail, integration with general relativity on large scales, and full accounting for all observations (such as the cosmic microwave background or Big Bang nucleosynthesis). Thornhill and the Thunderbolts community have engaged these points, often arguing that plasma and electrical effects have been underappreciated or misinterpreted.

For our purposes here, we do not need to resolve the debate. The value lies in the exploration itself—the willingness to consider that the universe may be more electrically alive and interconnected than the gravity-centric picture suggests.

## A Closing Reflection

Standing under a starry sky, it is humbling to consider that the pinpricks of light we see may be sustained not only by ancient fires deep within but by ongoing flows of electric power through cosmic filaments—Birkeland currents linking star to star, galaxy to galaxy, in a grand, dynamic web.

Wallace Thornhill's work invites us to reclaim a sense of wonder and interconnectedness in our cosmology. Whether these ideas ultimately complement, modify, or challenge the standard model, they remind us that science advances through bold questions and open-minded examination of nature's clues.

What if the universe is, at its heart, electric?

The currents are there. The question is whether we choose to see them.
