Supernova 1987A is the closest supernova event since the invention of the telescope. It was first seen in February 1987 in the nearby Magellanic cloud, a dwarf companion galaxy of the Milky Way, and only 169,000 light years from Earth. Close observation since 1987 has now provided proof that supernovae are catastrophic electrical discharges focused on a star.
>> IMAGE CAPTION: The enigmatic and beautiful structure of SN1987A with its three axial rings. The brightening of the equatorial ring is obvious. The two bright stars are just in the field of view and are not associated with the supernova.
A supernova is one of the most energetic events witnessed in the universe. The accepted explanation is that it occurs at the end of a star's lifetime, or red giant stage, when the star's nuclear fuel is exhausted. There is no more release of nuclear energy in the core so the huge star collapses in on itself. If sufficiently massive, the imploding layers of the star are thought to rebound when they hit the core, resulting in an explosion, and the blast wave ejects the star's envelope into interstellar space. The bright equatorial ring is caused by the collision of exploded matter from the star with the remnants of an earlier stellar "wind." The two faint rings are a problem. The best that theorists have been able to manage is to postulate some kind of rotating beam from an assumed supernova remnant, sweeping and lighting up a shell of gas expelled at an earlier epoch. The ad hoc nature of these explanations is obvious.
The detection of a pulsar remnant after some supernovae is explained by the implosion of the stellar core to produce a neutron star. Pulsars emit bursts of radiation up to thousands of times a second. It is believed that a pulsar must be a super-collapsed stellar object that can spin up to thousands of times a second and emit a rotating beam of X-rays (like a lighthouse). Commonsense suggests that this mechanical model is wrong when some pulsars rev beyond the redline, even for such a bizarre object.
A recent example of conventional thinking can be seen on the Chandra website. On August 17, a news story was posted: Supernova 1987A: Fast Forward to the Past.
Recent Chandra observations have revealed new details about the fiery ring surrounding the stellar explosion that produced Supernova 1987A. The data give insight into the behavior of the doomed star in the years before it exploded, and indicate that the predicted spectacular brightening of the circumstellar ring has begun.. The site of the explosion was traced to the location of a blue supergiant star called Sanduleak -69Â 202 (SK -69 for short) that had a mass estimated at approximately 20 Suns.
Subsequent optical, ultraviolet and X-ray observations have enabled astronomers to piece together the following scenario for SK -69: about ten million years ago the star formed out of a dark, dense, cloud of dust and gas; roughly a million years ago, the star lost most of its outer layers in a slowly moving stellar wind that formed a vast cloud of gas around it; before the star exploded, a high-speed wind blowing off its hot surface carved out a cavity in the cool gas cloud.
The intense flash of ultraviolet light from the supernova illuminated the edge of this cavity to produce the bright ring seen by the Hubble Space Telescope. In the meantime the supernova explosion sent a shock wave rumbling through the cavity. In 1999, Chandra imaged this shock wave, and astronomers have waited expectantly for the shock wave to hit the edge of the cavity, where it would encounter the much denser gas deposited by the red supergiant wind, and produce a dramatic increase in X-radiation.
The latest data from Chandra and the Hubble Space Telescope indicate that this much-anticipated event has begun. Optical hot-spots now encircle the ring like a necklace of incandescent diamonds. The Chandra image reveals multimillion-degree gas at the location

Neutrinos get produced when electrons and protons are forced into neutrons via inverse beta decay, which only happens at ridiculous pressures. They can't be produced by electromagnetic processes - they're weak byproducts only.

The crucial evidence for the electrical nature of supernovae must come from experiment and observation. Anthony L.

It was titled Characteristics for the Occurrence of a High-Current, Z-Pinch Aurora as Recorded in Antiquity. [lanl.gov] In it he explained the unusual characteristics of a high-energy plasma discharge. He discussed mega-ampere particle beams and showed their characteristic 56- and 28-fold symmetry. He wrote: "A solid beam of charged particles tends to form hollow cylinders that may then filament into individual currents. When observed from below, the pattern consists of circles, circular rings of bright spots, and intense electrical discharge streamers connecting the inner structure to the outer structure."

Actually, recent models show that the bounce doesn't cause the explosion, since the outward-propagating shockwave stalls at some point within the stellar envelope. The current idea is that the explosion is caused by the neutrinos from the core, that get absorbed by the outer envelope and heat it up to crazy temperatures. Sure, the cross section for an individual neutrino to interact is miniscule; but with so many neutrinos being produced, enough of them interact to cause the explosion.

First, if the story, as it showed up early this morning on
I've seen many replies under this story crying "crackpots!" and "quacks!".
But I haven't read even one yet that suggests some simple principles or facts which can be used to debunk the basic claim of the plasma cosmologists and the Electric Universe proponents: that plasma physics (i.e. electrodynamics as embodied in the behavior of plasmas) is not given enough credit when scietific models and theories that attempt to explain stellar and interstellar phenomenon.
And I am all ears. I studied physics in college and was well on my way towards a B.A. in that discipline when I decided to try my hand as an entrepreneur during the dot-com boom. I think I've developed a fairly sensitive internal "b.s. meter" over the course of my lifetime. And I try to "keep up" in my personal (albeit hobbyist) study of science, with space physics and cosmology being my dominant interests. I read stuff on the "popular science" level and I am also comfortable reading papers of a more technical nature. I self-admittedly have a more philosophical bent in my musing upon these matters, but that is not a variant of the excuse, "I'm not so good at math" -- I am actually fairly competent when it comes to advanced mathematics.
Several weeks ago, I read the story on
On the one hand, you have the plasma physicists/cosmologists that believe that the behavior of stars, galaxies, galactic clusters, etc. are governed not primarily by the gravitational force but rather gravity AND electrodynamics, with electrodynamics dominant in many contexts. And they pretty much stop with that assertion and confine most of their work to exploring it.
The Electric Universe enthusiasts go farther, and are trying to develop an all-encompassing framework in which they see every aspect of the universe (from the subatomic to the intergalactic) and its history as governed by the "Electric Force."
Am I true believer in the so-called "Electric Universe?" No. I actually find members of that end of the spectrum in question to be a bit too eager to engage in polemics, and that doesn't impress me. On the other hand, I will say that I find myself highly sympathetic to the work and claims of plasma physicists like Dr. Anthony Peratt [lanl.gov].
Here's why, in a nutshell: Since I was a little kid I've been fascinated by ideas like black holes, neutron stars, the "big bang," grand unified theories, etc., etc., etc. In fact, it was my reading Timothy Ferris' Galaxies [amazon.com] when I was in the 2nd grade that planted the seeds for my future interest in pursuing physics as a career. I read Hawking's A Brief History of Time [amazon.com] in the 6th grade, "understood" it, and from there began a more rigorous self-directed study into more advanced treatments of physics and mathematic

How are these "catastrophic electrical discharges" occur and funciton?
As I understand the gibbering drivel that poses for the hypothesis of the electric universe, the claim is that the stars become positively charged due to the loss of electrons in a stellar wind. There is then some huge discharge episode that causes the supernove.
Of course, this flies in the fact of everything that is known about stellar winds. In the case of the sun, we know that the wind is electrically neutral, from in situ measur
