Yet another WTF moment in science? Cosmic rays don't necessarily come from Supernova?
Edited on Tue Aug-30-11 03:48 PM by HysteryDiagnosis
Why am I not surprised? Because this was predicted by people who look through the correct end of the telescope.

“The mechanism for the acceleration of cosmic rays needs to be completely revised,” says Piergiorgio Picozza, a physicist at the University of Rome Tor Vergata in Italy. Picozza is a co-author of a March 3 paper in Science detailing the new observations of the Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics, or PAMELA, instrument.

Cosmic rays aren’t actually rays. They’re fast-moving particles that carry an extraordinary amount of energy and continuously bombard the Earth from every direction. The most popular explanation for the origin of these particles points to shock waves created by far-off supernovas, one of the few phenomena in the cosmos powerful enough to impart such energy.

According to that explanation, known as the diffusive shock acceleration mechanism, clouds of charged gas rush outward during a supernova and generate strong magnetic fields. These magnetic fields could accelerate charged particles to tremendous speeds and eject them into space.

Orbiting hundreds of kilometers above Earth, the PAMELA detector spent three years collecting cosmic ray particles; mostly nuclei of hydrogen and helium with energies ranging from a billion to a trillion electron volts, which is comparable to the energy of protons in the biggest particle accelerator in the United States.

1. I'm not sure I see the conflict here. Cosmic "rays" were never
rays of anything. They've always been particles. And their origins are only a theory. Why is it odd that other sources are being sought? Can you explain?

2. Until they look at the role of z-pinch in light years long plasma currents they won't find
the answer. And the people who consider me an idiot should see just how many idiots there are reading at this site, all over the globe at all hours of the day.

Although exploding stars (supernovae) are misapprehended to be kinetic events involving shock waves and rebound phenomena, interpreting them as the points where cosmic Birkeland currents create "z-pinch" vortices brings everything into focus. Magnetic fields have been detected in space. Those fields are thought to be generated by electric currents flowing through and around galaxies along light-years long "transmission lines" called Birkeland current filaments. Magnetic forces constrict the filaments, twisting them around each other and forming z-pinch compression zones. What are called "double layers" by plasma physicists form in the stellar circuit.

Nobel prize winner Hannes Alfvén described a double layer as, "... a plasma formation by which a plasma—in the physical meaning of this word—protects itself from the environment. It is analogous to a cell wall by which a plasma—in the biological meaning of this word—protects itself from the environment."

In an Electric Universe, there is another mechanism for cosmic ray acceleration and that is the "exploding" double layer, first described by Irving Langmuir in 1929. A double layer forms in plasma when electric current flows through it.

3. Oh, I should have known. Never mind.
Woo.com

Why do I bother?

4. Yes, why do you bother? You have doubts, therefore you bother. n/t

5. Exactly.
This poster has LONG been known for invading the science forum with "Electric Universe" claptrap.

6. Can I just pull you up on something?
"And their origins are only a theory"

You ought to know better than to phrase it that way when discussing science. "Only a hypothesis", surely?
