[/quote] What do you mean IF, it simply is a state of matter... Heat something enough and you will break the bonds and create free electrons and turn any matter into plasma or just use ionizing radiation. http://public.lanl.gov/alp/plasma/TheUniverse.html Plasma is by far the most common form of matter known. Plasma in the stars and in the tenuous space between them make up over 99% of the visible universe and perhaps most of that which is not visible. On earth we live upon an island of "ordinary" matter. The different states of matter found on earth are solid, liquid, and gas. We have learned to work, play, and rest using these states of matter. Sir William Crookes, an English physicist, identified another, more fundamental, state of matter in 1879. In 1929, Nobel Laureate Irving Langmuir gave this state a name, plasma. He borrowed the term from medical science because the matter with which he worked resembled life itself. It formed cells through bifurcation and often acted in a complicated and unpredictable manner. Plasma is defined as an assemblage of charged particles called electrons and ions that react collectively to forces exerted by electric and magnetic fields. [b]Given its nature, the plasma state is characterized by a complexity that vastly exceeds that exhibited in the solid, liquid, and gaseous states. Correspondingly, the study of the physical and especially the electrodynamical properties of plasma forms one of the most far ranging and difficult research areas in physics today.[/b] From spiral galaxies to controlled fusion, this little-known state of matter, the fundamental state, is proving to be of ever greater significance in explaining the dynamics of the universe and in harnessing the material world for the greatest technological result. http://plasmauniverse.info/ubiquitous.html#what [/quote] [quote:Anonymous Coward 619959:MV8xNjAxNTU2XzI5RUYzQzE1] "Cosmic dust can, in the presence of plasma, create formations known as plasma crystals. An international team of researchers published a study in the Aug.14, 2007, issue of the New Journal of Physics (PDF here http://iopscience.iop.org/1367-2630/9/8/263/pdf/1367-2630_9_8_263.pdf, abstract here http://iopscience.iop.org/1367-2630/9/8/263) that indicates that these crystals may be more sophisticated than anyone realized. In simulations involving cosmic dust, [b]the researchers witnessed the formation of plasma crystals displaying some of the elementary characteristics of life -- DNA-like structure, autonomous behavior, reproduction and evolution."[/b] http://www.metafilter.com/80344/All-these-worlds-are-yours-except-Europa-Attempt-no-landing-there When plasma comes into contact with a dust cloud, dust particles gather an electric charge by sucking up electrons from the surrounding plasma. This core of electrons in turn pulls in positively charged ions, forming plasma crystals. In the scientists' simulations, which were performed on the International Space Station and in a zero-gravity environment at a German research facility, the plasma crystals sometimes developed into corkscrew shapes or even the double-helix shape of DNA. These helix-shaped crystals retain an electric charge and show what the researchers called a self-organizing ability. "So they form DNA-like shapes, reproduce, pass on their structure or genetic code, "eat" plasma, evolve and die." http://science.howstuffworks.com/weird-life.htm "Complex plasmas may naturally self-organize themselves into stable interacting helical structures that exhibit features normally attributed to organic living matter." http://iopscience.iop.org/1367-2630/9/8/263 [/quote] :spock: "Its life Captain, but not as we know it." [/quote] Ironic isn't it, all this time we're searching for life in the universe and the visible universe is 99.9% plasma. The search for life needs to be renamed to the search for life like us. There is no set definition of what life is just some guidelines and plasma meets them all. [/quote]

Discovered by a German astronomer in 1950, the Biermann process predicts that a magnetic field can spring up spontaneously from nothing more than the m
otion of charged particles. Plasma, or charged particle gas, is abundant in space.
Scientists believe that large clouds of gas collapsing into galaxies sent elliptically shaped bubbles of shockwaves through the early universe, touching off flows of electric current in the plasma of the intergalactic medium.
Anyone who has built an electromagnet in middle school science class is familiar with this concept, Drake said.
"If you can make current flow, you make a magnetic field," Drake said.
The question in astrophysics was what could have generated the current. This experiment demonstrated that such asymmetrical shockwaves could do the job.

It's about time they began to take plasma cosmology seriously and stop believing in the creation myth that is the standard theory of the big bang.
