plasma presence
Hi
I have some questions and I hope someone have time to answer them and not only indicate a link
Is the plasma in the "empty" space omnipresent ?
That is, is there no place in space where plasma does not exist ?
Is plasma allways organised in doubel layers ?
Double layers are supposed to make the plasma stable. What is the reason for that ?
What is forcing the double layers to take such a form ?
R

Re: plasma presence
Short answer: yes. All of the observable universe consists of, by observation and extrapolation, partly or fully ionized matter, all of which behaves according to plasma principles (depending on rate of ionization). A small percentage of ionziation triggers plasma behaviour in a gas.rickard wrote:Is the plasma in the "empty" space omnipresent ?
It depends on plasma temperature, ionization, bulk dynamics, as well as electric and magnetic influences, which plasmas responds strongly to. Filamentation and cellular structures are overall typical characteristics of plasmas.rickard wrote:Is plasma allways organised in doubel layers ?
Some links though. This site contains some good information and images of astrophysical plasma and various types of double layers:rickard wrote:Double layers are supposed to make the plasma stable. What is the reason for that ?

Also check out Infogalactic for a better-than-Wikipedia coverage on the plasma subject:

Last but not least, check out the Essential Guide to the Electric Universe, where one can dig into various relavant categories (hereby plasmas and double layers):

Re: plasma presence
Thanks a lot for the answer.
And the links you provided where very informative and useful

Re: plasma presence
Hi again
One more question
If the "empty" space is filled with plasma, how does that influence the speed of light from the stars ?
Why does the plasma form double layers ?
According to Alfvén the plasma forms "cell" structures. Is the plasma alive ?

Re: plasma presence
Siggy did a great job answering your posts. I would simply add that even the mere presence of cosmic rays means that space is actually filled with plasma and there is no such thing as 'empty' space.rickard wrote:Hi again

The net influence on light IMO is seen in photon redshift. Light always travels at C, but photons experience inelastic scattering, and they lose some of their momentum in the presence of EM and temperature gradients. Photons are constantly traversing and bumping into EM field gradients in space, and transferring some of their momentum to the plasma in space, which is why the Hubble distance relationship is observed.

Redshift isn't caused by metaphysical nonsense like "space expansion', dark energy or inflation. It's caused by the ordinary (and lab demonstrated) loss of momentum to the plasma medium through which the photons must pass.

Re: plasma presence
My questions where not about the origin of redshift. But your reflection that light decrease in speed as a result of its passage through the plasma seems as an interesting explanation. But how does that fit with Halton Arps "intrinsic redshift" ?Michael Mozina wrote:Siggy did a great job answering your posts.
